AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN 332 PM CDT MON JUL 22 2013 .SHORT TERM...(THIS EVENING THROUGH TUESDAY) ISSUED AT 311 PM CDT MON JUL 22 2013 AMPLE INSTABILITY AND WIND SHEAR VALUES LATE THIS AFTN ACROSS PORTIONS OF WC WI WILL LEAD TO AN ISOLD SVR STORM. OTHERWISE...MUCH DRIER AIR WILL SURGE SOUTHEAST ACROSS THE UPPER MIDWEST WITH DEW POINTS ALREADY LOWERING INTO THE 50S IN WC/CENTRAL MN AS OF 3 PM. THIS AIR MASS WILL HOLD OVER THE AREA THRU TUESDAY AFTN WITH TEMPS 5 TO 10 DEGREES BELOW NORMAL FOR LATE JULY. .LONG TERM...(TUESDAY NIGHT THROUGH MONDAY) ISSUED AT 311 PM CDT MON JUL 22 2013 WEST/NORTHWEST FLOW DEVELOPING ALOFT WILL PLAY HAVOC ON THE SPD OF SHRTWV/S ACROSS THE NORTHERN PLAINS AND UPPER MIDWEST WED/THU. ALTHOUGH MODELS HAVE LEAN WEAKER ON A MCS TYPE PRECIPITATION EVENT LATE TUESDAY NIGHT/WED...THERE REMAINS ENOUGH CONSISTENCY TO INCREASE TO HIGH END CHC POPS...ESPECIALLY ACROSS WC MN WHERE BETTER WAA AND MOISTURE ADVECTION EXISTS TUE NIGHT/WED MORNING. TYPICALLY...THESE TYPE OF SYSTEM BEGIN TO DECAY BY LATE MORNING AS THE CAPS STRENGTHENS. HOWEVER...ANY LEFTOVER BOUNDARIES WITH THIS MCS WILL LEAD TO MORE AFTN/EVENING DEVELOPMENT. BY LATE THU/EARLY FRIDAY A STRONGER FRONTAL BOUNDARY WILL MOVE ACROSS THE UPPER MIDWEST. TIMING AND OVERALL MOISTURE AVAILABILITY REMAINS IN QUESTION. HOWEVER...THE ENERGY ASSOCIATED WITH THIS SYSTEM LOOKS IMPRESSIVE ENOUGH TO WARRANT CONTINUED CHC POPS. ONCE THIS SYSTEM MOVES OFF TO THE E/SE...A VERY COOL TEMPERATURE REGIME WILL DEVELOP. HIGHS SAT/SUN WILL LIKELY BE 10 DEGREES BELOW NORMAL WITH DEW POINTS LIKELY IN THE UPPER 40S TO LOWER 50S. USING THE STANDARDIZED ANOMALIES ON 50H/85H TEMPS/HEIGHTS REMAIN 1 TO 2 UNITS BLW AVERAGE FOR LATE JULY. NOT UNTIL EARLY NEXT WEEK DOES ANY SIGNS OF 80S RETURN TO THE UPPER MIDWEST. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z TUESDAY AFTERNOON) ISSUED AT 1245 PM CDT MON JUL 22 2013 THE COLD FRONT NOW EXTENDS FROM ROUGHLY SIOUX FALLS...TO THE WESTERN TWIN CITIES METRO...TO JUST SOUTHEAST OF DULUTH. SO FAR...THE FRONT IS JUST MANAGING TOWERING CUMULUS CLOUDS WITH CLOUDS BASES NEAR 3000 FT IN MOST LOCATIONS. A BRIEF PERIOD /1-3 HOURS/ OF MVFR CEILINGS IS POSSIBLE WITH THE COLD FRONT. WE ARE ALSO SEEING SOME SHOWERS DEVELOP IN NORTHWEST WI...BUT MINNESOTA AND WESTERN CENTRAL WI REMAIN STORM FREE AT THIS POINT. KEAU HAS THE BEST CHANCE FOR THUNDER. WE NOW THINK STORMS WILL MISS ALL THE OTHER TAF SITES BESIDES KEAU. KMSP... THE COLD FRONT /WITH A WIND SHIFT TO THE W-NW/ PASSED BY THE OFFICE HERE IN CHANHASSEN AT ABOUT 1245 PM...SO IT WILL BE AT THE AIRPORT WITHIN 30 MINUTES OR SO. GIVEN THAT THE STORM ACTIVITY HAS BEEN SUPPRESSED UP UNTIL NOW...WE THINK THERE IS NOT ENOUGH TIME TO DEVELOP STORMS BEFORE THE COLD FRONT PASSES THROUGH. STORM CHANCES LOOK BETTER 50-75 MILES EAST OF THE AIRPORT. COULD HAVE LINGERING STRATO CU WITH A SCT-BKN 2500-3500 FT DECK LATE THIS AFTERNOON OR EARLY EVENING...BUT THE MORE WIDESPREAD CLOUDS SHOULD REMAIN IN NORTHERN/WESTERN MN. NO AVIATION WEATHER CONCERNS TOMORROW. /OUTLOOK FOR KMSP/ TUE/TUE NIGHT...VFR. WINDS N 5 TO 10 KT. WED...VFR. CHANCE OF SHRA/TSRA LATE NIGHT. WINDS S 5 KT. THU...CHC SHRA/TSRA.
