Nearly whiteout conditions downtown, worst of the day so far.

The new intern at DVN is stuck at the WFO and will be spending the night and doing the morning balloon launch as well. Welcome to the NWS. :devilsmiley:

Poor guy...or not! He'll have lots of stories to tell years from now.

How many more inches of snow do you think the metro QC area will get?

Incredible observation! Pure awesome!

LOL--gotta love how the observer has to append a CB to the cloud layer for TS reports. Nothing like 100 foot Cumulonimbus bases.

.DISCUSSION...

ISSUED 845 PM CST TUE FEB 1 2011

LOW PRESSURE CURRENTLY JUST WEST OF LAWRENCEVILLE WILL CONTINUE

TO TRACK NORTHEAST INTO CENTRAL INDIANA OVERNIGHT. LOW LEVEL

WARM ADVECTION JUST AHEAD OF THE SURFACE LOW HAS HELPED PUSH

TEMPERATURES ABOVE FREEZING ALONG AND SOUTH OF INTERSTATE 70

WITH MOST OF THE PRECIPITATION NOW IN THE FORM OF RAIN. IN

FACT...THE OOZ ILX SOUNDING INDICATED A SHALLOW WARM LAYER FROM

850 TO 800 MB WITH THAT LAYER WARMING A COUPLE OF DEGREES SINCE

NOON TODAY. FURTHER EAST AND SOUTHEAST...A MORE PRONOUNCED WARM

NOSE NOTED ON RUC FORECAST SOUNDINGS WHICH SUGGESTS FREEZING

RAIN...SLEET AND SNOW WILL CONTINUE ACRS EAST CENTRAL ILLINOIS...

WITH RAIN AND SLEET ACRS THE FAR SOUTHEAST BEFORE IT CHANGES OVER

TO LIGHT SNOW AS THE STORM SYSTEM PULLS AWAY FROM THE AREA.

FURTHER TO THE NORTHWEST OF THE LOW...HEAVY SNOW ACCOMPANIED BY

LIGHTNING AND THUNDER...ESPECIALLY ALONG AND NORTH OF INTERSTATE

74 THIS EVENING...WILL GRADUALLY SHIFT NORTH OF THE AREA AFTER

MIDNIGHT AS THE LOW MOVES AWAY. AS THE LOW APPROACHED SOUTHERN

ILLINOIS EARLIER THIS EVENING ACCOMPANIED BY IMPRESSIVE 3 HOURLY

PRESSURE FALLS...SURFACE WINDS INCREASED DRAMATICALLY WITH REPORTS

OF 45 TO 55 MPH COMMON TO THE NORTH OF THE PRESSURE FALL CENTER.

WE EVEN RECEIVED A REPORT OF A 64 MPH WIND GUST AT ROANOKE AROUND

530 THIS EVENING.

DESPITE A GRADUAL DECREASE IN COVERAGE OF THE PRECIPITATION LATER

TONIGHT...ESPECIALLY SOUTH OF SPRINGFIELD AND TAYLORVILLE...BLIZZARD

MORNING AS STRONG WINDS WILL PRODUCE CONSIDERABLE BLOWING AND

DRIFTING SNOW WITH NEAR WHITE-OUT CONDITIONS EXPECTED. NO CHANGES

TO THE HEADLINES FOR THE OVERNIGHT HOURS.

Good news for those south of I-70 here in IL, rising above freezing will bring an end to the icing in that area.

With these pressure falls it's little surprise we are seeing TSSN across central and northern IL.

Patrick...

Looks like a dry slot sneaking into lower Mi.. Any thoughts. DTX shifting their axis of high precip a tick north. Still think another 6 out of this beast for the city of detroit. Waiting on convective band too..

I have been watching it too....obs in the dry slot have been over 42KT winds and radar shows convective-like cells embedded on it's NW-E flanks....it will be short lived and could pop a flash of lightning. Yeah I think another 6 to 8 inches is about right.

Just what our cement needs, a little bit of epoxy. Gonna need dynamite or 70 degree temps to make a dent in this.

Agreed. I've got the 1/2" or so base layer of sheer ice from last night with 4" or so of sleet on top of it and now another layer of ice to complete the sandwich as the freezing rain has returned. I don't think the Arctic blast the next few days will help matters much!

Anyone from S/E Michigan alive? :D

Meh, I'm here.

Everything about the snowfall has been the same for the past 3 hours (since I last posted). The flakes have gotten a little bigger and the visibilities have gotten a little lower, nothing to really post about.

I'll be sure to post an update when if anything really interesting happens.
