Area forecast discussion, Apr 30, 5:51 PM CDT, 2 hours 54 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN 551 PM CDT FRI APR 30 2010 .UPDATE... UPDATED TO INCLUDE 00Z AVIATION DISCUSSION BELOW. && .DISCUSSION... SHORT TERM TRENDS INDICATE SIG SEVERE WEATHER HAS ENDED OVER WEST CENTRAL WISCONSIN. THUNDER THREAT WILL REMAIN OVER THE AREA INTO THE EVENING AS UPPER TROUGH STILL MEANDERING NORTH ACROSS THE EASTERN DAKOTAS. POCKET OF INSTABILITY REMAINS OVER THE FAR EAST AND UNDER UPPER LOW. THIS COLD POOL MAY YET CLIP THE FAR NORTHWEST PORTION OF THE CWA THIS EVENING. OTHERWISE...ACTIVITY SHOULD WANE PRETTY MUCH BY SUNSET. DIURNALLY DRIVEN SHOWERS POSSIBLE ACROSS THE FAR NORTHERN CWA SATURDAY AND SUNDAY AS UPPER LOW COLDER TEMPERATURES ALOFT REMAINS OVER THE NORTHERN PORTION OF THE AREA. COOLER TEMPERATURES AND MORE CLOUDS FOUND THAT REGION DURING THE PERIOD. LONGER TERM REMAINS TROUBLESOME AS AMPLIFIED WEATHER PATTERN FLATTENS AS JET STREAM LIFTS NORTH ACROSS THE NORTHERN CONUS AT LEAST EARLY IN THE PERIOD. LOOKS LIKE THE BEST POTENTIAL WITH FRONT MOVING THROUGH LATE TUESDAY NIGHT AND WEDNESDAY AND AGAIN LATER THU NIGHT AND FRIDAY AS A WEATHER SYSTEM TRAVELS SOUTH OF THE AREA. THICKNESS/85H TEMPERATURES CONTINUE TO COOL AND CLOSE TO CRITICAL RAIN/SNOW LEVELS BY LATER FRIDAY. && .AVIATION.../00Z TAF ISSUANCE/ MAIN AVIATION CONCERN THROUGH THE FORECAST PERIOD WILL BE STRONG WINDS DURING THE DAY ON SATURDAY AS VERY STEEP LAPSE RATES DEVELOP ACROSS THE AREA ALLOWING FOR 30+KT WINDS TO BE MIXED DOWN THROUGH THE DAY. PRIOR TO THAT... THE CURRENT SHRA ACTIVITY OVER THE AREA SHOULD SETTLE DOWN QUICKLY THIS EVENING OVER MOST OF THE AREA... WITH PERHAPS A FEW SHRA STICKING AROUND LONGER OVER THE NORTHERN PORTION OF THE AREA WHERE DEEPER MOISTURE AND LARGE SCALE FORCING PERSIST FOR A BIT LONGER. ELSEWHERE... THE LOSS OF DIURNAL HEATING WILL ALLOW FOR THE SHRA TO END AND SKIES TO GENERALLY SCATTER OUT THROUGH THE EVENING HOURS. THE UPPER LEVEL COLD POOL WILL MOVE CLOSER TO THE AREA ON SATURDAY... ALTHOUGH THE HEART OF IT WILL BE OFF TO THE NORTHWEST. HOWEVER... THERE WILL BE A SUFFICIENT COMBINATION OF COLD AIR ALOFT AND SURFACE WARMING ALONG WITH DECENT BOUNDARY LAYER MOISTURE TO PRODUCT BKN CU ACROSS THE AREA AS THE DAY UNFOLDS. ALTHOUGH THESE CEILINGS COULD INITIALLY BE AROUND 3K FT AGL... THEY WILL QUICKLY LIFT AND BE VFR BY AFTERNOON. WINDS WILL PICK UP DRAMATICALLY DURING THE MORNING... WITH SOUTHWEST WINDS SUSTAINED ABOVE 15KT ACROSS THE ENTIRE AREA BY MID MORNING... AND PERHAPS ABOVE 20KT BY AFTERNOON... WITH GUSTS AOA 30KT LOOKING LIKELY WITH SOME GUSTS NEAR 40KT OVER THE TYPICALLY WINDY AREAS. KMSP... A FEW SHRA COULD LINGER FOR THE VERY FIRST HOUR OR SO OF THE FORECAST PERIOD... THEN EXPECT CLOUDS TO SCATTER OUT THROUGH THE EVENING... WITH TIMING DIFFERENCES OF AN HOUR OR TWO POSSIBLE FROM WHAT IS FORECAST. TIMING ON THE WIND INCREASE TOMORROW SHOULD BE CLOSE TO FORECAST TIME FRAME... WITH GOOD CONFIDENCE ON FORECAST SPEEDS... ALTHOUGH THEY MAY EVEN BE A BIT UNDERDONE... SO LATER FORECASTS WILL NEED TO KEEP AN EYE ON THAT POSSIBILITY. && .MPX WATCHES/WARNINGS/ADVISORIES... MN...NONE. WI...NONE. && DWE/TRH
