Area forecast discussion, Apr 8, 1:54 PM CST, 7 hours 36 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI 254 PM CDT SUN APR 8 2001 FORECAST FOCUS ON PRECIPITATION CHANCES TONIGHT THROUGH MONDAY NIGHT. ONLY COMPLETE MODEL WE HAVE THIS RUN IS THE NGM. OTHER MODELS ARE COMING IN VERY SLOWLY AND IN PIECEMEAL FASHION. DUE TO THIS FACT HAVE RETAINED MUCH OF THE OLD FORECAST AND RELIED ON SPC FOR SOME INSIGHT INTO PRECIPITATION CHANCES TONIGHT THROUGH MONDAY NIGHT. SPC PUTS SOUTHERN WISCONSIN IN SLIGHT RISK FOR SEVERE WEATHER TONIGHT WITH A DEVELOPING MCS NEAR KANSAS CITY THIS EVENING IN RESPONSE TO AN UPPER LEVEL DISTURBANCE CURRENTLY OVER OKLAHOMA EVIDENT ON VISIBLE/WATER VAPOR IMAGERY. MCS PREDICTED TO FIRE OFF THIS DISTURBANCE AND MOVE EAST-NORTHEAST TONIGHT WITH THE MEAN FLOW. MCS WILL AFFECT SOUTHERN WISCONSIN TONIGHT WITH THE BEST CHANCE FOR SEVERE WEATHER OVER EXTREME SOUTHERN WISCONSIN WITH WIND DAMAGE BEING THE PRIMARY CONCERN. THE TAIL END OF THE MCS MAY AFFECT OUR CWA INTO THE EARLY MORNING HOURS SO WILL KEEP CHANCES IN FOR THE MORNING. DEPENDING ON WHERE THE BOUNDARIES LIE ON MONDAY WILL DETERMINE WHERE CONVECTION FIRES OFF TUESDAY AFTERNOON. NGM PROGS LOW PRESSURE TO APPROACH SOUTHERN WISCONSIN MONDAY AFTERNOON WHICH WILL FIRE OFF MORE CONVECTION. AGAIN WILL KEEP THE PREVIOUS FORECAST FOR THIS PERIOD. TUESDAY WILL BE RELATIVELY QUIET AS A LOW DEVELOPS OVER THE SOUTHERN PLAINS. COULD SEE SOME ELEVATED CONVECTION LATE TUESDAY NIGHT NORTH OF THE WARM FRONT AS THE FRONT MAKES ITS WAY NORTHWARD. IN THE FAR TERM THE FRONT SHOULD SIT OVER OUR AREA ON WEDNESDAY WITH THE CHANCE FOR CONVECTION ALL DAY. COULD SEE SOME SHOWERS ON THURSDAY AS THE LOW DEEPENS AND MOVES THROUGH NORTHERN WISCONSIN. LOW HAS MANY CHARACTERISTICS OF YESTERDAYS LOW...WITH THE CHANCE FOR SOME WINDY CONDITIONS DURING THE DAY. ALTHOUGH IT IS IN THE EXTENDED PERIOD...IT DEFINITELY BEARS WATCHING IN THIS VERY ACTIVE WEATHER PATTERN. A RIDGE WILL BRING QUIET WEATHER ON FRIDAY WHILE SATURDAY AND SUNDAY COULD SEE SHOWERS DUE TO A SERIES OF LOWS MOVING THROUGH OUR AREA. .MKX...NONE. KURIMSKI
