UPDATED: Major Servere Weather Outbreak Possible Thursday

[Galvan]

A fall Severe Weather outbreak is possible throughout much of the area Late Wednesday and Thursday.

Weather Models suggest that an intensifying low pressure system is going to assemble over the Plains, as this happens air will be drawn aloft powerful jet stream leads to strengthening southerly winds which by Thursday are to be stacked vertically tens of thousands of feet through the atmosphere above Chicago. The howling flow—whistling through Chicago airspace at 60+ m.p.h. only 2,000 ft. above ground—sweeps 70°+ warmth and moist 65°+ dew point air into the area and is likely to feed waves of showers and t-storms. It’s beyond that point at which there is the greatest concern for severe weather.


Heres what to expect Thursday:

Very High Winds, Damaging Hail, Very Heavy rainfall flooding rainfall and possible Tornadoes.

I will keep an eye on this weather system and give updates when needed.

The Storm Prediction Center has placed the whole Chicago area in a Moderate Risk for Severe Storms Thursday.

Well, you might be a little disappointed, the Severe stuff probably wont be here until Mid-day tomorrow.

UPDATED:

The National Weather Service has issued an advisory for our area:


Severe thunderstorms likely Thursday afternoon...

An intensifying storm system currently in the plains will surge
northeast into the mid and upper Mississippi River valley
Thursday. Strengthening winds will draw moisture from the Gulf and
help destabilize the area tonight. Showers and thunderstorms
should start developing tonight as the first wave rotates through
the area as a warm front. These first storms are not likely to be
severe considering the time of day and weaker available energy.

Behind this first wave... storms should subside to showers in the
morning hours tomorrow. The second wave however will arrive with
the cold front driving east across the Mississippi River several
hours after sunup. If skies break open in the mid to late
morning hours... solar heating will add energy to an already vigorous
looking system. These storms will arrive in the early afternoon
into north central Illinois and finally clear northeast Illinois
and Northwest Indiana in the early to mid evening.

Strong downbursts to 70 mph are possible with these storms Thursday
afternoon and evening. Large damaging hail are also probable. If
not threatening enough... a few tornadoes are also possible.

Residents and businesses in northern Illinois and Northwest
Indiana should begin preparing now for this significant bout of
severe weather. Gather valuables and your weather radio and keep
tuned to TV and radio to keep abreast of this developing severe
storm threat.

Too bad where I am its just going to rain nonstop for a day and a half. Probably up to 2 inches of rain in about 24 hours though. That should be exciting.

[DejaVuGurl1203]

Yay

[Aero737]

Too far easy, too far east, too far east..

[Galvan]

A TORNADO WATCH IS IN EFFECT FOR NORTHEAST ILLINOIS AND NORTHWEST
INDIANA THIS EVENING.

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS TONIGHT ACROSS PARTS
OF THE OUTLOOK AREA...GENERALLY EAST OF A GARY TO KANKAKEE TO
GIBSON CITY LINE. THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS TO
INCLUDE THE REST OF THE OUTLOOK AREA.

[Galvan]

Im not sure its going to be too far east.

Especially with the WW out for the Chicago Metro area.

[DejaVuGurl1203]

We had two storms, it was interesting. The second one brought us lots of hail pounding against the windows. Probably the first time I've seen hail in a long time.

[Trailblazer Tony]

Well, this morning during my 1.5 mile walk to Kinkos to print out (about 4am) for class, i was hit with some powerful winds and LOTS of rain (which made for a very soggy and horrible morning). This evening was even better with some hail, strong winds, lots of rain, and an enormous and BRIGHT rainbow over the city. Quite a cool experience, i took quite a few pics, if you want them, PM me.

Thanks Mike for the updates throughout!

[rct2wizard360]

Tru dat Amber.

First time I've seen hail in around 5-6 years.

[cycamps]

[rich12_16]

[Danhockey04]

Had to go chase my car cover yesterday after the wind blew it off the Fiero, but otherwise nothing really bad here.
