AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
255 AM CST SUN JAN 17 2016
.SHORT TERM...
233 AM CST
THROUGH MONDAY...
THE MAIN FORECAST CONCERNS THROUGH THE SHORT TERM PERIOD WILL BE THE
DANGEROUS WIND CHILLS ACROSS THE AREA THROUGH MONDAY MORNING. AS FOR
HEADLINES...WE HAVE ISSUED A WIND CHILL ADVISORY FOR THE ENTIRE AREA
TONIGHT INTO MONDAY MORNING...AND WILL KEEP THE WIND CHILL ADVISORY
FOR MY NORTHERN AREAS GOING THROUGH NOON MONDAY.
DEEPER COLD IS GRADUALLY ADVECTING OVER THE AREA EARLY THIS
MORNING...WITH TEMPERATURES LIKELY TO FALL NEAR...OR EVEN BELOW ZERO
IN SOME AREAS BY DAYBREAK. ADDITIONALLY...A COUPLE OF MID-LEVEL PV
ANOMALIES...CURRENTLY SHIFTING SOUTHEASTWARD WITHIN THE SOUTHERN
PERIPHERY OF A LARGER SCALE UPPER LOW OVER THE UPPER MIDWEST...WILL
MOVE OVER THE AREA EARLY THIS MORNING. LARGER SCALE FORCING FOR
ASCENT ASSOCIATED WITH THIS FEATURE...IN COMBINATION WITH A
MESOSCALE BAND OF STRENGTHENING FRONTOGENESIS SHOULD SUPPORT AN AREA
OF LIGHT SNOW EARLY THIS MORNING...MAINLY FOR AREAS SOUTH OF I-80.
CURRENT RADAR IMAGERY AND AREA OBSERVATIONS INDICATE LIGHT SNOW
ONGOING ACROSS SOUTHERN IOWA...WITH A FEW FLURRIES NOW INTO CENTRAL
ILLINOIS. THIS AREA OF SNOW LOOKS AS THOUGH IT WILL DEVELOP EASTWARD
INTO CENTRAL ILLINOIS OVER THE NEXT SEVERAL HOURS...AND THIS COULD
RESULT IN SOME MINOR ACCUMULATIONS OF A DUSTING ACROSS MY SOUTHERN
COUNTIES. OTHERWISE...THE MAIN SNOW MAKER FOR THE NEXT FEW DAYS WILL
BE THE LAKE EFFECT SNOWS...WHICH SHOULD REMAIN FAVORED ALONG THE
EASTERN SHORES OF LAKE MICHGAN. HOWEVER...SOME MINOR SNOW
ACCUMULATIONS ARE POSSIBLE ACROSS NORTHERN PORTER COUNTY...AS SOME
INTERMITTENT SNOW SHOWERS IMPACT THAT AREA.
OTHERWISE...THE BITTERLY COLD TEMPERATURES AND WIND CHILLS WILL BE
THE MAIN CONCERN FOR THE REST OF THE AREA THROUGH MONDAY. WIND
CHILLS AS OF THIS WRITING ARE ALREADY DROPPING INTO THE TEENS BELOW
0 ACROSS MUCH OF FAR NORTHERN ILLINOIS...AND THIS WILL CONTINUE TO
BE THE CASE THROUGH THE DAY TODAY...AND ESPECIALLY TONIGHT...WHEN
WIND CHILLS OF 20 TO 25 BELOW ARE LIKELY AREA-WIDE. AS FOR THE
HEADLINES...WE DECIDED TO TAKE THE CURRENT ADVISORY AREA ACROSS FAR
NORTHERN ILLINOIS...WHICH WAS ORIGINALLY SET TO EXPIRE AROUND MIDDAY
TODAY...AND EXTENDED IT THROUGH MIDDAY MONDAY. WHILE WIND CHILLS
COULD WARM ABOVE -20 DURING THE AFTERNOON TODAY...IT WOULD ONLY BE
FOR A COUPLE HOURS. THEREFORE...RATHER THAN ENDING THE ADVISORY FOR
THIS AREA...THEN HAVING TO REISSUE LATER THIS AFTERNOON...WE FELT IT
PRUDENT TO JUST CONTINUE IT AS ONE LONG ADVISORY. ELSEWHERE...WIND
CHILLS REALLY DONT LOOK TO DROP TO -20 UNTIL THIS EVENING.
THEREFORE...AREAS MAINLY ALONG AND SOUTH OF I88...WILL NOT BE IN A
WIND CHILL ADVISORY UNTIL LATER THIS EVENING THROUGH MIDDAY MONDAY.
EITHER WAY THOUGH...IT WILL BE A VERY COLD COUPLE OF DAYS AREA-
WIDE.
KJB
&&
.LONG TERM...
253 AM CST
MONDAY NIGHT THROUGH SATURDAY...
AFTER ANOTHER COLD NIGHT MONDAY NIGHT...A WARMING TREND WILL
COMMENCE ON TUESDAY INTO WENDESDAY AS THE FLOW TURNS SOUTHERLY AGAIN
ON THE WESTERN PERIPHERY OF SURFACE HIGH...WHICH WILL SHIFT OVERHEAD
MONDAY NIGHT. THIS SHOULD ALLOW HIGH TEMPERATURES TO RETURN TO
NEAR THE SEASONAL AVERAGES LATER IN THE WEEK.
ONCE THE MAIN UPPER LOW SHIFTS OVER THE NORTHEASTERN COAST OF THE
U.S. ANOTHER MID LEVEL DISTURBANCE IS FORECAST TO QUICKLY SHIFT OVER
THE REGION TUESDAY NIGHT INTO WEDNESDAY. WITH ISENTROPIC UPGLIDE
EXPECTED TO INCREASE AHEAD OF THIS DISTURBANCE...A LIGHT
ACCUMULATING SNOW EVENT STILL LOOKS LIKE A DECENT POSSIBILITY OVER
THE AREA. OVERALL...IT DOES NOT APPEAR TO BE A BIG EVENT...BUT A 1
TO 3 INCH EVENT IS CERTAINLY POSSIBLE GIVEN THE THERMO PROFILE WILL
LIKELY STILL FAVOR A HIGHER LIQUID TO SNOW RATIO.
FOLLOWING THIS QUICK MOVING SYSTEM...MODEL AND ENSEMBLE GUIDANCE IS
IN GOOD AGREEMENT WITH ANOTHER MID-LEVEL SYSTEM DIGGING OVER THE
SOUTHERN PLAINS AROUND THE THURSDAY TIMEFRAME. GIVEN WHAT APPEARS TO
BE A STRONG SYSTEM SETTING UP OVER THE NORTHEAST PACIFIC DURING THIS
PERIOD...THE RAPID AMPLIFICATION OF A DOWNSTREAM UPPER RIDGE IS
LIKELY OVER THE WESTERN CONUS. THIS WESTERN CONUS RIDGE WILL THEN
LIKELY FAVOR THE SOUTHERN PLAINS DISTURBANCE TO SHIFT EASTWARD
ACROSS THE SOUTHERN CONUS THROUGH LATE WEEK. BECAUSE OF THIS...IT
APPEARS THIS STORM SYSTEM MAY REMAIN FAR ENOUGH TO THE SOUTH TO
MISS THE AREA. HOWEVER...IN SPITE OF THIS...THE SYNOPTIC SURFACE
PRESSURE PATTERN COULD FAVOR A NORTH-NORTHEASTERLY WIND INTO
NORTHERN ILLINOIS LATER IN THE WEEK AS HIGH PRESSURE BUILDS IN
OVER THE MIDWEST. IF THIS WERE TO OCCUR IT COULD SUPPORT SOME LAKE
EFFECT SNOW SHOWERS INTO NORTHEASTERN ILLINOIS. WITH THIS IN MIND
I DID LEAVE SOME LOW END POPS IN LATER IN THE WEEK TO COVER THIS
POSSIBILITY.
