.DISCUSSION...
246 PM CST
MAIN FORECAST CONCERNS WILL CENTER AROUND THE CLOUDS AND COLD
TEMPERATURES IN THE SHORT TERM...THEN AN EXTENDED PERIOD OF TRANQUIL
WEATHER WITH SEASONABLE TEMPERATURES AND NO PRECIPITATION THROUGH
NEXT WEEKEND.
CYCLONIC FLOW WITH MID-UPPER TROF...AND CORE OF COLDEST AIR MOVING
ACROSS THE UPPER MISSISSIPPI VALLEY THIS AFTERNOON. SOUTHERN EDGE
OF AN EXTENSIVE STRATO-CU DECK IN RESPONSE TO THIS...IS SHIFTING
EAST ACROSS NORTHERN IA AND IL THIS AFTERNOON. NEAREST REPORTED
FLURRIES HAVE BEEN ACROSS FAR NORTHERN IA INTO WESTERN WI. NOTHING
NOTED CLOSE TO THE IL BORDER. CANT RULE OUT A FLAKE OR TWO NEAR
THE WISCONSIN BORDER LATE AFTERNOON-EARLY EVENING...BUT SEE NO
NEED TO EVEN MENTION FLURRIES IN THE FORECAST. AS UPPER TROF
SHIFTS EAST ACROSS THE GREAT LAKES THIS EVENING...AND
RIDGING/WARMING ALOFT DEVELOPS...CLOUDS SHOULD DISPERSE. AS
CLEARING OCCURS AND WINDS DIMINISH SOME OVERNIGHT...HEAT SHOULD
RADIATE OUT PRETTY WELL...ALTHOUGH WITH SURFACE HIGH STILL SITTING
DWON NEAR STL BY MORNING...THERE MAY BE ENOUGH WIND TO KEEP
TEMPERATURES FROM BOTTOMING OUT TOO MUCH. EXPECT MID AND UPPER
TEENS IN OUTLYING AREAS AND TYPICAL COLD SPOTS...TO MID 20S IN THE
HEART OF THE CITY. EXPECT TEMPERATURES TO MODERATE TUESDAY...BUT
WITH SUCH A COLD STARTING POINT IN THE MORNING...WILL STRUGGLE TO
GET TO AROUND 40 OR LOWER 40S MOST AREAS.
MODELS BRING A WEAK SHORT WAVE THROUGH THE GREAT LAKES AROUND
THURSDAY-THURSDAY NIGHT BUT ONLY EXPECT SOME MID AND HIGH CLOUDS
WITH THIS AS LOWER ATMOSPHERE REMAINS VERY DRY. 12Z EUROPEAN RUN
DEVELOPS A CLOSED UPPER LOW AFTER THE TROF PASSES EAST OF THE
LOCAL AREA...AND EVENTUALLY DEEPENS IT INTO A POWERFUL STORM ON
THE EAST COAST NEXT WEEKEND AND INTO EARLY NEXT WEEK...BUT DRY
QUIET WEATHER TO CONTINUE HERE.
TEMPERATURES WILL BE CLOSE TO NORMAL WEDNESDAY THROUGH THE
WEEKEND WITH LITTLE DAY TO DAY TEMPERATURE CHANGE.
