Lake Effect Snow Forecast

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

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.
