DISCUSSION
ISSUED AT 125 PM CDT SUN MAR 30 2025
THE LINE OF STORMS WE HAVE BEEN OUTLOOKING HAVE FIRED AND ARE MOVING
EASTWARD ACROSS THE SOUTHERN HALF OF IL THIS AFTERNOON. WE ARE
EXPECTING THESE STORMS TO BE OUT OF THE CWA BY 00Z -- EXITING OUT OF
SOUTHEASTERN IL. ALL HAZARDS ARE STILL EXPECTED THROUGHOUT THE EVENT
AND A TORNADO WATCH (#70) IS IN EFFECT THROUGH 00Z.
MONDAY WILL BE A RELAXED DAY COMPARED TO WHAT HAS BEEN GOING ON.
HIGHS WILL BE IN THE UPPER 40S TO LOW 50S, WITH LOW TEMPERATURES
AROUND 30 DEGREES. TEMPERATURES WILL REBOUND BY WEDNESDAY BACK INTO
THE 70S.
AFTER TODAY'S SEVERE WEATHER, WE ARE WATCHING TUESDAY NIGHT INTO
WEDNESDAY FOR THE NEXT DECENT CHANCE FOR SEVERE WEATHER. SPC HAS US
OUTLOOKED FOR A SLIGHT RISK (LEVEL 2 OF 5) TUESDAY (DAY 3) AND AN
ENHANCED RISK (LEVEL 3 OF 5) WEDNESDAY (DAY 4). THINKING IS THE
OUTLOOK FOR TUESDAY IS FOR OVERNIGHT TUESDAY INTO EARLY WEDNESDAY
MORNING, AS THERE LOOKS TO POTENTIALLY BE TWO ROUNDS OF SEVERE
WEATHER. THE OVERNIGHT ROUND (ASSOCIATED WITH A WARM FRONT)
CURRENTLY DOESN'T LOOK AS IMPRESSIVE AS THE DAYTIME CONVECTION
WEDNESDAY. THE SECOND ROUND WILL BE FIRING ALONG THE PASSING COLD
FRONT AND LOOKS TO BE IN THE AFTERNOON INTO THE EVENING. OUTSIDE OF
THE STORMS, WEDNESDAY LOOKS TO BE ANOTHER WINDY ONE (GUSTS AROUND 30-
35 KNOTS).
OVERALL THE EXTENDED WILL BE AN ACTIVE AND WET PERIOD AND START TO
APRIL, ESPECIALLY FOR SOUTHEASTERN IL. SEVERAL ROUNDS OF
PRECIPITATION LOOK POSSIBLE FOR SOUTHEASTERN IL OVER THE WEEKEND,
INCLUDING A SLIGHT RISK FOR EXCESSIVE RAINFALL ON WEDNESDAY AND
THURSDAY. HIGHS WILL BE IN THE 60S FOR THE ENTIRE CWA THROUGH THE
WEEKEND.
