AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN 443 PM CDT SAT MAY 26 2007 .DISCUSSION... NEXT SYSTEM IS EVIDENT ON WV IMAGERY AS IT PUSHES ACROSS VANCOUVER ISLAND THIS SUNDAY. THE NAM...GFS AND ECMWF BUILD A SHARP UPPER LEVEL RIDGE OVER THE PACIFIC NORTHWEST IN THE WAKE OF THE SYSTEM MOVING ONSHORE. THIS SERVES TO SLOW THIS FEATURE DOWN SOME AND DIG IT SOUTHWARD AS IT CLEARS THE ROCKIES THROUGH TUESDAY. THIS WILL MEAN LESS SYNOPTIC SCALE FORCING (AS SEEN IN THE 500-300 MB LAYER Q-VECTOR FORCING). ABUNDANT MOISTURE IS FLOWING NORTHWARD ACROSS THE CENTRAL PLAIN STATES IN ADVANCE OF THIS NEXT SYSTEM AND THIS WILL CERTAINLY MEAN MORE UNSTABLE AIR MOVING INTO OUR CWA ON MEMORIAL DAY. HOWEVER...THE STRONGER DEEP LAYER (0-6 KM BULK SHEAR) IS FORECAST TO PUSH TO THE NORTHWEST OF OUR AREA WHICH SHOULD MEAN A LOWER POTENTIAL FOR ROTATING SUPERCELLS EARLY THIS WEEK. DEEP LAYER SHEAR IS NOT EXPECTED TO PICK UP IN OUR CWA UNTIL TUESDAY...AND BY THAT TIME...THE HIGHER CAPE FIELD HAS MOVED OFF TO OUR EAST. THUS...WE WOULD EXPECT GARDEN VARIETY THUNDERSTORMS WITH THIS NEXT SYSTEM. MUCH WARMER CONDITIONS EXPECTED FOR MONDAY AND TUESDAY WITH DEW-POINTS PUSHING BACK INTO THE UPPER 50S AND LOWER 60S...WITH A SUBSTANTIAL COOL DOWN TUESDAY NIGHT THROUGH THE REMAINDER OF THE WORK WEEK. SOMEWHAT WARMER CONDITIONS EXPECTED NEXT WEEKEND...HOWEVER...YOU WOULDNT THINK SO LOOKING AT THE THICKNESS FORECAST FORM THE GFS. && .AVIATION.../FOR 00Z TAF ISSUANCE/ SOME PATCHY MIDDLE AND HIGH CLOUDS OVER THE SOUTHWEST PORTION OF THE FORECAST AREA NEAR KRWF SUNDAY EVENING. DRY WEST-NORTHWEST AIRFLOW AFLOFT WILL CONTINUE TO PROVIDE CLEAR SKIES OVER THE REST OF TAF SITES. UPPER RIDGE MOVES OVER THE WESTERN GREAT LAKES AND WISCONSIN BY MONDAY MORNING. MID LEVEL WARM ADVECTION EXPECTED TO COMMENCE THROUGH THE NIGHT ACROSS MUCH OF THE UPPER MIDWEST AND INTO MEMORIAL DAY. MID LAYER RELATIVE HUMIDITY INCREASES TO 70 PERCENT OVER MUCH OF THE FORECAST AREA. THUS...CLOUDS/CEILING EXPECTED TO EXPAND IN COVERAGE OVER THE TAF SITES DURING THE PERIOD. CEILINGS SHOULD BE BASICALLY AT OR ABOVE 8000 FT AGL. CLOUDS EXPECTED TO THIN OUT DURING THE AFTERNOON IN WESTERN MINNESOTA. && .MPX WATCHES/WARNINGS/ADVISORIES... MN...NONE. WI...NONE. &&
