Area forecast discussion, May 23, 2:00 PM CDT, 2 hours 44 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
200 PM CDT WED MAY 23 2001

FORECAST CHALLENGES FOR NEXT FEW DAYS ARE CHCS FOR RAIN AND TEMPS
WITH UPPER LEVEL LOW XPCTD TO SINK INTO IL.

LATEST SFC ANALYSIS INDICATED A LOW IN XTRM NE IA...WITH A
TROF/SECONDARY CDFNT FROM XTRM WRN IL INTO ERN KS. THIS WAS
COMBINING WITH DIFFERENTIAL HTG AND COLD ADVECTION ALOFT TO PRODUCE
SHRA/TSRA IN ILX FORECAST AREA. THIS CONVECTION IS XPCTD TO PERSIST
INTO THE EVENING HOURS...BEFORE DISSIPATING A FEW HOURS AFT DARK.

THE UPPER LOW...CENTERED IN XTRM SE MN ACRDG TO THE WATER VAPOR
LOOP...WILL DRIFT SE INTO NW IL BY TOMORROW MORNING. THIS WILL LEAD
TO A WIDESPREAD BKN-OVC SKY COVER...ESPECIALLY IN NW PARTS OF THE
FORECAST AREA. ENOUGH BREAKS IN THE CLOUDS SHOULD RESULT IN THE
DEVELOPMENT OF SHRA/TSRA DURING THE AFTN-EVE ALONG AND SE OF I-55.
TEMPS WILL BE A BIT COOLER TOMORROW THAN THE PAST COUPLE OF DAYS
WITH MID 50S NW TO THE LWR 60S SE.

THE MODELS ARE CONSISTENT IS PROJECTING THAT THE UPR LOW WILL WOBBLE
AROUND IN NRN IL/SRN WI/NW IND FRIDAY INTO ERLY SUNDAY. THIS WOULD GIVE
CENT/SE IL MOSTLY CLOUDY CONDITIONS AND DAILY CHCS FOR SHWRS/T-STORMS
PRIMARILY DURING THE AFTN-ERLY EVE HOURS. AM XPCTG TEMPS TO BE A BIT
WARMER ON FRIDAY AND SAT IN THE 60S...BUT STILL WELL BELOW SEASONAL
NRMLS.

AN UPR TROF IS XPCTD TO APPCH THE WEST COAST AND COME ONSHORE LATE
SUNDAY. THIS SHOULD HELP GIVE THE CLOSED LOW A PUSH TO THE EAST...
PUTTING CENT/SE IL IN ANTICYCLONIC FLOW IN THE LOW LEVELS BY MONDAY.
WILL CONTINUE THE TREND KEEPING THE WX DRY WITH A WARMING TREND ON
MEMORIAL DAY AND INTO MIDWEEK.
