Area forecast discussion, Jun 3, 3:05 PM CDT, 1 hour 55 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND FORKS ND 305 PM CDT SUN JUN 3 2012 .SHORT TERM...TONIGHT THROUGH WEDNESDAY FORECAST CHALLENGES INCLUDE LOW-END PRECIPITATION CHANCES LATE THIS AFTERNOON AND EVENING...FOLLOWED BY TEMPERATURES THROUGH MID-WEEK. GFS/NAM/ECMWF/GEM ARE IN GOOD AGREEMENT AND WILL CONTINUE TO USE A BLENDED SOLUTION FOR THIS FORECAST PACKAGE... BUT PREFER RAP/HRRR/SPC 4 KM WRF FOR NEAR TERM CONVECTIVE TRENDS. SURFACE BOUNDARY IS LOCATED ALONG A LINE FROM CANDO TO JUST EAST OF BISMARCK. SPC MESOANALYSIS SHOWS 1500 TO 2000 J/KG OF SURFACE BASED CAPE WITH NO CIN ALONG THIS AXIS...BUT LOW-MID LEVEL DYNAMIC FORCING/SHEAR IS VERY WEAK. CU FIELD ALONG BOUNDARY MAY STILL PRODUCE A FEW ISOLATED SHOWERS AND THUNDERSTORMS ALONG NOSE OF 300 HPA JET STREAK...BUT WITH NO RADAR ECHOES...WILL TRIM POPS BACK INTO THE 20 TO 40 PERCENT RANGE LATE THIS AFTERNOON. SPEED OF BOUNDARY IS ALSO A BIT SLOWER THAN PREVIOUSLY ADVERTISED...SO WILL ADD 20 POPS ALONG AND EAST OF THE VALLEY IN THE 00 TO 03 UTC PERIOD. ELSEWHERE...LINGERING LIGHT RAIN SHOWERS ACROSS NORTHWEST MN WILL MOVE EAST AND OUT OF THE FORECAST AREA NO LATER THAN MIDNIGHT. ADDITIONAL RAINFALL AMOUNTS WILL BE MINIMAL.

DESPITE CLEARING SKIES AND LIGHT WIND...NIGHTTIME LOWS WILL BE IN THE 50S WITH SURFACE TO 850 HPA LAYER TEMPERATURES FROM +16 TO +18 C. MONDAY THROUGH WEDNESDAY...AN UPPER LEVEL RIDGE WILL BUILD ACROSS THE NATION/S MID-SECTION AS AN OMEGA BLOCKING PATTERN TAKES SHAPE WITH BOOKEND TROUGHS ACROSS THE PACIFIC NORTHWEST AND NEW ENGLAND. SURFACE HIGH PRESSURE WILL DOMINATE THE NORTHERN PLAINS AND WITH LARGE SCALE SUBSIDENCE...EXPECT DRY CONDITIONS THROUGH TUESDAY NIGHT AND MOST OF WEDNESDAY. DID INTRODUCE A 20 POP WEST OF THE VALLEY ON WEDNESDAY AS PROMINENT SHORT-WAVE ROTATES AROUND PACIFIC NORTHWEST TROUGH...BUT THINK MAJORITY OF ASSOCIATED PRECIPITATION WILL REMAIN SOUTH AND WEST OF THE FORECAST AREA. EXPECT LITTLE DAY TO DAY VARIATION IN TEMPERATURES THROUGH MID- WEEK AS THERMAL PROFILES ARE STAGNANT. HIGHS WILL CLIMB INTO THE UPPER 70S TO LOWER 80S AND LOWS WILL BOTTOM OUT IN THE 50S TO LOWER 60S. OVERALL...A VERY PLEASANT BEGINNING TO THE FIRST FULL WORK WEEK IN JUNE. .LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY MODELS INITIALIZED WELL AND REMAIN IN GENERAL AGREEMENT SO STAYED WITH A BLENDED SOLN FOR THIS FORECAST. LITTLE CHANGE EXPECTED TO THE UPPER LEVEL PATTERN AS IT IS EXPECTED TO REMAIN FAIRLY STAGNANT WITH THE RIDGE REMAINING OVER THE NRN PLAINS. SOME WEAKENING OF THE RIDGE IS EXPECTED...ALLOWING FOR INCREASED CHANCES OF -RW/TRW...WITH TEMPS STAYING NEAR TO ABOVE SEASONAL NORMS. && .AVIATION... VFR CONDITIONS EXPECTED WITH CONTINUED CLOUDINESS ACROSS THE AREA AND PERSISTING THRU THE TAF PERIOD. SOUTHERLY WINDS WILL SLOWLY BECOME WESTERLY OVERNIGHT AFTER FRONTAL PASSAGE. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...NONE. MN...NONE. && ROGERS/HOPKINS
