LOT regarding tomorrow and tomorrow night

THURSDAY WILL START OUT NICE BUT DO NOT BE DECEIVED. PVA AND H5

HEIGHT FALLS LEADING STRONG SHORT WAVE TROUGH AS IT ARRIVES IN UPPER

MIDWEST THURSDAY MORNING WILL CAUSE RAPID DEEPENING OF SURFACE LOW

PRESSURE OVER NORTHERN GREAT LAKES...WITH A STRONG COLD FRONT

SWEEPING TOWARD CWA. OUT AHEAD OF FRONT...WSW FLOW AND H85 TEMPS

WARMING TO LOW TO MID TEENS WILL ALLOW FOR TEMPERATURES TO REACH

UPPER 60S FAR NORTH...LOW 70S CHICAGO AND WEST...AND MID AND A FEW

UPPER 70S FAR SOUTH BY EARLY AFTERNOON. DEWPOINTS WILL RISE TO THE

50S TO AROUND 60 DEGREES...LEADING TO THE DEVELOPMENT OF MINOR

INSTABILITY. AS FRONT APPROACHES...DESPITE MEAGER

INSTABILITY...DYNAMICS WILL BE QUITE IMPRESSIVE. STRONG H5 HEIGHT

FALLS AND PVA RESULT IN OFF THE CHARTS OMEGA NOTED ON BUFKIT

SOUNDINGS. STAYED CLOSED TO PREVIOUS FCST WITH PRECIP FORECAST FOR

TOMORROW...WITH SCATTERED SHOWER ACTIVITY AND HIGHEST POPS EAST.

BROADENED ISOLATED THUNDER MENTION TO MOST OF CWA DUE TO

IMPRESSIVE DYNAMICS...BUT AT THIS POINT THINK SEVERE POTENTIAL IS

LOW.

AFTER FRONT SWEEPS THROUGH REGION BY MID AFTERNOON...FOCUS QUICKLY

TURNS TO STRONG NORTHWEST WINDS. STRONG LOW PRESSURE TRACKING ACROSS

NORTHERN LOWER MICHIGAN BY THURSDAY EVENING WILL CAUSE RAPID

TIGHTENING OF PRESSURE GRADIENT...WITH SOME ISALLOBARIC COMPONENT

POSSIBLE AS WELL. STRONG CAA...AS H85 TEMPERATURES CRASH FROM THE

TEENS TO MID SINGLE DIGITS...WILL STEEPEN LOW LEVEL LAPSE RATES AND

LEAD TO MIXING TO AT LEAST 900 MB. MODEL SOUNDINGS SHOW 40 KT +

WINDS NOT FAR OFF THE DECK MID AFTERNOON THROUGH THURSDAY NIGHT FOR

MUCH OF AREA...WHICH SHOULD EASILY MIX DOWN. THUS HOISTED WIND

ADVISORY FROM 21Z THURSDAY TO 10Z FRIDAY FOR ALL BUT SOUTHERN TIER

OF COUNTIES

holy smokes..18z NAM is a bit faster regarding the 850mb jet max coming south tomorrow evening. Has a wide area of 60kt winds and a max of 75kts around MSN tomorrow night at 0z.

If we can mix some of that down with or without the showers there could be some gusts over 50mph I would imagine. If a strong trop fold accompanies the potential deep mixing there could be some very strong gusts. Gonna be interesting to watch.

I already think we will have gusts to 50mph even if we don't mix to 850mb but we'll see.

I'd love to see a cold air funnel... I know it would be fairly anti-climatic, but cool none the less. I had never even heard about them untill I moved out here.

First mention of snow for the season by NWS CLE:

ONCE THE FRONTAL BOUNDARY MOVES EAST...COLD AIR ADVECTION WILL BEGINTO TAKE PLACE. THE COLD AIR ADVECTION WILL LINGER INTO THE WEEKENDAS 1000 TO 500 MB THICKNESSES DROP DOWN TO AROUND 540 SATURDAY ANDSATURDAY EVENING. 850 MB TEMPERATURES WILL DIP TO -3 TO -4 CSATURDAY INTO SUNDAY. AT THIS POINT...SINCE THE LAKE IS SO WARMYET...I THINK THERE IS A MUCH GREATER CHANCE THAT WE WILL NOT SEETHE FORMATION OF SNOW GRAINS JUST YET. SO WILL LEAVE THE MENTION OFSNOW OUT OF THE FORECAST FOR NOW. HOWEVER...I CANT RULE OUT ANISOLATED FEW SNOW GRAINS IN THE HIGHEST ELEVATIONS TO THE EAST.

Another tornado has been confirmed in Indiana by IND. This one occurred early Monday morning and was rated an EF1. I think a Severe Thunderstorm Warning was issued for this one.

"A small brief tornado occurred in northwest Jennings County early Monday morning, September 26. The tornado began at approximately 12:33 AM EDT around 6 miles west of North Vernon along County Road 700 West between County Roads 150 North and 300 North. The tornado destroyed a pole barn and damaged 2 homes before lifting around 12:34 AM EDT. The path was approximately a half mile long and 75 yards wide. Based on the damage, the tornado was rated an EF1 on the Enhanced Fujita scale with winds estimated near 100 mph.

This same storm also produced straight line wind damage, knocking down trees, near St. Paul in northwest Decatur County at 12:55 AM EDT and also golf ball size hail in New Castle around 1:30 AM EDT."
