Lake Effect Snow Forecast

sean@visualastronomy.com (Sean Welton) — Thu, 20 Nov 2008 21:51:00 +0000

The NWS has issued a lake effect snow warning for tonight (11-20-08). According to the NWS, some areas of Geauga county could receive over a foot of snow by Saturday. Sounds like it could get real bad close to the lake, maybe including thundersnow!

From the NWS:

Statement as of 3:42 PM EST on November 20, 2008

... Lake effect snow warning remains in effect until 4 am EST Saturday...

A lake effect snow warning remains in effect until 4 am EST Saturday.

Lake effect snow will continue to develop and spread inland across the area. The snow will be heavy at times tonight... Friday and Friday night... eventually tapering off during the day Saturday. Rumbles of thunder are also possible especially within a few miles of the Lake Erie.

Snow accumulations are expected to be heaviest during the event from eastern Cuyahoga County... east across Inland Lake... northern Geauga and northern Trumbull counties.

Accumulations will reach up to 6 inches tonight and then as much as 8 inches Friday and Friday night where squalls persist.

By Saturday afternoon some of the higher elevations of Geauga County could see between 1 and 2 feet of snow...

We're Back!

Okay, so it took way longer to get back to this blog than I had expected! I got kind of caught up taking care of my other blog, Visual Astronomy, which has really taken off as of late. What I've learned while tweaking that blog will be applied here.

So I'll be starting articles and posts back up here pretty soon!

Enjoy!

Slight Convective Risk

sean@visualastronomy.com (Sean Welton) — Fri, 01 Aug 2008 17:33:00 +0000

Today's SPC convective outlook indicates that we could be in for some strong storms today. We'll see how it turns out, as strong daytime heating will make our atmosphere pretty unstable. All we need is something to kick it all off, which is possible.

Technical SPC Mesoscale Discussion:

ANOTHER CORRIDOR OF SEVERE STORM DEVELOPMENT APPEARS POSSIBLE ACROSS PARTS OF IL/IND/OH THROUGH LATER AFTERNOON AHEAD OF THE CONVECTION DEVELOPING FARTHER NORTH WITH THE AMPLIFYING SHORT WAVE TROUGH. AN AXIS OF STRONG TO LOCALLY EXTREME INSTABILITY EXISTS OVER THESE AREAS ALONG A RESIDUAL WEAK STATIONARY FRONTAL ZONE. WHILE LARGE SCALE ASCENT WILL BE WEAKER ACROSS THESE AREAS...THERE MAY BE SUFFICIENT HEATING AND PERSISTENT LOW LEVEL CONVERGENCE TO AID STORM INITIATION IN THIS VERY UNSTABLE REGIME. AS FARTHER NORTH...SHEAR WILL INCREASE WITH TIME...AND EVENTUALLY...STRONGER FORCING WILL DEVELOP ACROSS THIS ZONE AS WELL. EXPECT STORMS MAY CONTINUE TO ORGANIZE IN THIS CORRIDOR THROUGH THE EVENING HOURS WITH SOME POSSIBILITY OF A BETTER ORGANIZED MCS FORMING. AMPLIFYING PATTERN SUPERIMPOSED ON THE POSSIBLE MCS SUGGESTS THE THREAT FOR DAMAGING WIND EVENT MAY INCREASE INTO THE LATE EVENING ACROSS PARTS OF IND/OH...AND PERHAPS SOUTH ACROSS THE OH RIVER.

Storms Dissipate and Weaken

It appears that the storms mentioned in today's NWS mesoscale discussions did not hold up after all. Click the following picture to see them dissipate shortly after moving into Ohio.

Finally, Some Drier Weather

sean@visualastronomy.com (Sean Welton) — Mon, 14 Jul 2008 21:51:00 +0000

For most of this week, Ohio will be under a high pressure system, meaning that the weather will most likely be pretty nice. No appreciable rain is expected throughout the Ohio valley, and temperatures should be rather warm, too. Finally, the area might get a chance to dry out a little bit from all the recent rain!

NAM model forecast for Tuesday July 15th, 2008. Note the large open area over Ohio. This is the high pressure system.

July 8, 2008 Severe Thunderstorm Pictures

sean@visualastronomy.com (Sean Welton) — Wed, 09 Jul 2008 01:34:00 +0000

Today, a rather strong squall line moved through Youngstown. At first I thought this storm was going to fizzle out and disappear before it even got here, so I wasn't paying much attention to it. I went out to put my car away and saw the storm had actually started looking decent, so I checked the radar and went out to get some pictures. The following photos show the gust front and shelf cloud passing over Youngstown, at approximately 6 PM EDT.

The shelf cloud approaching.

The shelf cloud passing overhead.

Roiling clouds seen after the passing of the shelf cloud.

More of the same clouds.

After these images were taken, I checked the radar again, and to my surprise, there was a tornado vortex signature (TVS) Southwest of Youngstown! This can be seen in the radar capture below. A TVS does not indicate the presence of a tornado; it merely shows that there is strong rotation in the storm. I tried to get a better view to my South, but ended up getting caught in the rain, so I didn't get any more pictures. At this point, the NWS warnings were playing on the radio, and the rain was getting to be quite torrential. I decided I was going to get out of there so that my car did not get dented by any hail, since the storm was indicated to be producing penny-sized hail. The TVS did not verify and there were no reports of funnel clouds in the Youngstown area.

Tornado Warning Issued for Toledo, 7-8-08

sean@visualastronomy.com (Sean Welton) — Tue, 08 Jul 2008 19:02:00 +0000

This tornado warning was issued for Toledo by the National Weather Service at 2:48 PM EDT, 7/8/08.

The National Weather Service in Cleveland has issued a

* Tornado Warning for...
Lucas County in Northwest Ohio...

Amazing Up Close Tornado Video!

sean@visualastronomy.com (Sean Welton) — Thu, 03 Jul 2008 02:17:00 +0000

I recently found this closeup video of a tornado while browsing the Eastern US Weather Forums. This isn't in Ohio, nor is it even in the US. Oddly enough, this happened near Stockholm, Sweden! In this video, a man in a car takes a nearly direct hit from a tornado! Watch closely around 1:20, that is where this video gets really interesting!

NOTE: This is not my video. I don't even know the person that took this video ;)

4th of July Forecasts

sean@visualastronomy.com (Sean Welton) — Thu, 03 Jul 2008 01:15:00 +0000

Current forecasts are calling for chances of rain and thunderstorms on Independence Day across Ohio. Most areas in Ohio are expecting a 60-70% chance of thunderstorms. The further South into the state of Ohio you go, the higher these chances will become. Sure would be nice if these storms missed us.

Powerful Storm in Northern Ohio

sean@visualastronomy.com (Sean Welton) — Thu, 03 Jul 2008 00:58:00 +0000

About a half-hour before I am writing this, a powerful storm moved through Toledo. Currently the storm is still moving Eastward, and will be upon Cleveland shortly. This storm has a very sharply defined "bow echo", the curved red region in the radar shown below. Bow echoes typically mark the region where air (and rain) are exiting the storm at high velocities. A member of a regional forum has clocked wind speeds near and potentially above 60 MPH in lower Michigan. This is a dangerous storm, if you must be outdoors, think safe.

Can You Find the Jet Stream?

sean@visualastronomy.com (Sean Welton) — Wed, 25 Jun 2008 16:11:00 +0000

Can you find the jet stream in this satellite image from today? I'll give you a hint.. Its the giant curved cloud...

IR satellite, 11:30 EDT, 6-25-08

Pretty neat, huh? Looks like the winds aloft are not only pulling off cloud material from the main storm in Indiana, but also popping up new storms along that line. According to the GFS model, wind shear picks up dramatically across this line, so there may be some storm action today!

Storms Possible Later This Week

sean@visualastronomy.com (Sean Welton) — Tue, 24 Jun 2008 16:23:00 +0000

Starting on Thursday, June 26, Ohio is under at least a slight risk of convective thunderstorms. Thursday's outlook states that we will be under a "slight" risk. The day is expected to produce severe weather across most of the Central and Midwestern US.

Convective outlook for Thursday, June 26. Issued 6/24/08 0744Z.

Friday and Saturday could turn out to be even stormier for the Ohio valley, as the SPC has already marked them on their Day 4-8 outlook. This means there is at least a 30% chance that Ohio will get some severe weather. Moist and unstable air, combined with moderate wind shear could support some organized severe storms capable of producing heavy rain and damaging winds.

Convective outlook for Thursday, June 26. Issued 6/24/08 0854Z.

Some Recent Thunderstorms Pictures

sean@visualastronomy.com (Sean Welton) — Mon, 23 Jun 2008 23:16:00 +0000

Lately, we've had a lot of thunderstorms, so I figured I would share some pictures I had taken of them.

This is a picture of a gust front we had come through Ashtabula, OH on June 21, 2008. I was at an open house and saw this. I told my friend, "Its about to get real windy", and sure enough, in about a minute, we had 20-30 mile per hour winds!

This is a view of the same gust front in Ashtabula, OH on June 21, but seen as it passed overhead.

Some low clouds I saw today (June 23, 2008) in Youngstown, OH. There were some pretty strong storms all across Ohio, but (to the best of my knowledge) none of them were tornadic.

The same low clouds in Youngstown, with a wider field of view.

More Rain, Thunderstorms

sean@visualastronomy.com (Sean Welton) — Mon, 23 Jun 2008 22:30:00 +0000

More thunderstorms are on their way across Ohio as I type this (6-23-08 3:30 PM EST). Several of the isolated cells have been severe thunderstorm warned, although it doesn't appear that anything is spinning yet. We've got enough wind shear for some of these cells to become organized, but the region's low to moderate instability is not seeming to really kick these into high gear yet. Either way, most of Ohio is going to get some rain.

Severe Thunderstorms 6-22-08

sean@visualastronomy.com (Sean Welton) — Sun, 22 Jun 2008 19:41:00 +0000

Currently in Youngstown, we are under a severe thunderstorm watch, as is a good portion of Ohio. Akron is currently tornado warned, after Cleveland radar picked up a tornado vortex signature. I would expect this to be upgraded within the next few hours, as indicated by this mesoscale discussion from the SPC:

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 593 CONTINUES.

ISOLATED SEVERE STORMS CAPABLE OF LARGE HAIL AND DAMAGING WINDS WILL CONTINUE ACROSS WW THIS AFTERNOON.

SCATTERED STRONG TO POTENTIALLY SEVERE TSTMS ARE IN PROGRESS AS OF 1915Z WITH THE MOST CONCENTRATED ZONE OF ACTIVITY FOCUSED WITHIN A LOW-LEVEL CONFLUENCE ZONE FROM NEAR CAK WWD TO SE OF FDY. 18Z ILN SOUNDING IS REPRESENTATIVE OF AMBIENT INFLOW ENVIRONMENT WITH STEEP LOW-LEVEL LAPSE RATES AND MODEST BOUNDARY LAYER MOISTURE... CONTRIBUTING TO SBCAPES OF 1000-1500 J/KG. THE PRESENCE OF AROUND 30 KT OF DEEP LAYER SPEED SHEAR SHOULD CONTINUE TO SUPPORT A FEW ORGANIZED STORMS CAPABLE OF DAMAGING WINDS AND SOME HAIL.

Expect some severe weather today, with chances of hail and high, possibly damaging winds. I'll try to post some pictures/video later tonight.

First Day of Summer 2008

sean@visualastronomy.com (Sean Welton) — Fri, 20 Jun 2008 18:21:00 +0000

Today (June 20, 2008) was the first official day of Summer in 2008. Officially speaking, Summer begins on the day that the sun is the farthest North in the sky. The following are the days surrounding this event.

June 17, 2008 - Earliest Sunrise of 2008
June 20, 2008 - Longest Day of 2008; First day of Summer 2008

Slight Severe Weather Risk - 6-21-08

sean@visualastronomy.com (Sean Welton) — Fri, 20 Jun 2008 14:14:00 +0000

According the the National Weather Service's Storm Prediction Center (SPC), Ohio will be under a slight risk of severe thunderstorm activity during June 21, 2008. Shown below is the current (as of 6-20-08 0800Z) SPC Day 2 convective outlook.

SPC Convective Outlook for 6-21-08

As stated in the outlook,

AFOREMENTIONED REINFORCING SHORTWAVE TROUGH AND AN ASSOCIATED WEAK COLD FRONT WILL SHIFT EAST/SOUTHEAST OVER THE MIDWEST ON SATURDAY. A ROUGHLY WEST-EAST ORIENTED AXIS OF 60S F SURFACE DEWPOINTS AND MODERATE INSTABILITY WILL EXIST ALONG/AHEAD OF THE SURFACE FRONT. TSTMS SHOULD INCREASE IN COVERAGE ESPECIALLY ACROSS THE OHIO VALLEY SATURDAY AFTERNOON...WITH SOMEWHAT MORE ISOLATED STORMS EXPECTED WESTWARD ACROSS THE CORN BELT/MIDDLE MO VALLEY AREAS. RELATIVELY STEEP LAPSE RATES AND MODERATE INSTABILITY OF 1500-2000 J/KG...ALONG WITH LARGELY UNIDIRECTIONAL WIND PROFILES WITH VERTICAL SHEAR AROUND 30 KT /0-6 KM/...SUGGEST MAINLY MULTICELL CLUSTERS CAPABLE OF DAMAGING WINDS AND SEVERE HAIL SATURDAY AFTERNOON AND EVENING.

Eastern OH Severe Outlook 6-16-08

sean@visualastronomy.com (Sean Welton) — Mon, 16 Jun 2008 15:38:00 +0000

According to the SPC mesoscale discussion #1416, there is the potential for severe weather to occur in the extreme Eastern end of Ohio. Most of the activity should occur in Pennsylvania and New York, but Eastern Ohio may see scattered cells popping up this afternoon. Text from MD #1416:

THUNDERSTORMS ARE EXPECTED TO INTENSIFY OVER PARTS OF WESTERN NY/PA BEFORE 17Z...THEN DEVELOP EASTWARD TOWARD SOUTHERN NEW ENGLAND DURING THE EARLY AFTERNOON. A WATCH IS LIKELY TO BE ISSUED IN THE NEXT COUPLE OF HOURS. VISIBLE SATELLITE IMAGERY SHOWS STRONG HEATING OCCURRING OVER WESTERN NY/PA...WHERE TEMPERATURES ARE WARMING INTO THE 70S. MODIFIED 12Z BUF SOUNDING SUGGESTS AIRMASS IS VIRTUALLY UNCAPPED ALREADY...WITH FURTHER HEATING ANTICIPATED THROUGH THE EARLY AFTERNOON. THUNDERSTORMS ARE EXPECTED TO DEVELOP RELATIVELY SOON AS NOSE OF MID LEVEL JET OVERSPREADS AREA AND CONVERGENCE STRENGTHENS ALONG COLD FRONT AND LAKE BREEZES. MUCAPE VALUES OF 1500-2000 J/KG AND STEEP MID LEVEL LAPSE RATES WILL YIELD RATHER STRONG UPDRAFTS AND THE THREAT OF LARGE HAIL. ALSO...SUBSTANTIAL DRY AIR ALOFT...STEEP LOW LEVEL LAPSE RATES...AND STRONG WESTERLY FLOW AT MID LEVELS WILL PROMOTE DAMAGING DOWNBURSTS IN STRONGER CELLS.

In plain English, this means that afternoon heating will cause the air to become unstable. That is, the air near the ground will become warm, while the air aloft will stay relatively cool. This will make the warmer air want to rise, and create updrafts, which lead to storm development. Those in the affected areas should monitor their local news stations and/or weather radios.

Cooler Weather Ahead

sean@visualastronomy.com (Sean Welton) — Mon, 16 Jun 2008 14:09:00 +0000

This upcoming week (June 15-21) is forecast to be much cooler than last week. Friday, June 20, looks to be the warmest day, with a high of only 76* F. Temps will be in the 60*'s all week. Although it might seem a little cool, it might be nice after a week of record highs. It is also forecast that there will be a good bit of rain all week.

Thunderstorms in Columbus

sean@visualastronomy.com (Sean Welton) — Thu, 12 Jun 2008 22:42:00 +0000

Columbus is currently (6-12-08 6:45PM) experiencing an isolated thunderstorm. This thunderstorm has been warned as a severe thunderstorm, and according to the radar, is producing small hail. Looks like a decent isolated cell so far. We'll see where it goes, and if we get anything here in Youngstown. Funny, I'm almost tempted to drive West a bit...

Base reflectivity, 0.5 * elevation angle radar image over Columbus, Ohio, 6-12-08.

June 12 Convective Outlook

sean@visualastronomy.com (Sean Welton) — Thu, 12 Jun 2008 13:57:00 +0000

The National Weather Service's Storm Prediction Center (SPC) issued this convective outlook for Friday June 12, 2008. This convective outlook depicts the possibility of severe thunderstorms. As you can see below, most of the Midwest and Ohio are included in the "SLGT" region, meaning there is a slight risk of severe thunderstorms, including heavy rain and hail.

SPC Day 2 Convective Outlook. Valid 6-13 1200Z to 6-14 1200Z

According to the SPC forecast:

LARGE SCALE LIFT ASSOCIATED WITH APPROACHING SHORTWAVE TROUGH AND 40-50 KT LOW LEVEL JET/LOW LEVEL WARM ADVECTION SHOULD SUSTAIN SLIGHTLY ELEVATED MCS FROM SERN KS INTO WRN MO EARLY FRIDAY MORNING. MUCAPES AROUND 1500 J/KG AND EFFECTIVE SHEAR NEAR 30 KT MAY SUPPORT AN ISOLATED SEVERE THREAT. HOWEVER...THESE STORMS ARE LIKELY TO BE MAINTAINED ENEWD INTO THE OH VALLEY AS STRONG DIFFLUENCE...ASSOCIATED WITH RIGHT ENTRANCE REGION OF JET MAX... SPREADS FROM SRN MO NEWD INTO THE OH VALLEY.

Current forecasts are calling for a 15-30% probability of severe thunderstorms.

More Storms in Ohio

sean@visualastronomy.com (Sean Welton) — Tue, 10 Jun 2008 02:58:00 +0000

As I'm writing this, at about 11 PM on June 9, another system of storms is approaching Youngstown, and is already rolling through most of northern Ohio. They aren't currently forecasted to be severe, so these mainly linear storms shouldn't be a problem other than some potential heavy rainfall. They are quite impressive looking though, as you can see in the following image of the storms as of approximately 9:45 PM.
