Area forecast discussion, Jul 14, 4:00 PM CDT, 2 hours 13 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DULUTH MN 400 PM CDT TUE JUL 14 2003 THERE ARE NO SIGNIFICANT FORECAST PROBLEMS. HIGH PRESSURE SHOULD CLEAR SKIES TONIGHT AND KEEP THEM CLEAR EARLY WEDNESDAY. A TROUGH APPROACHES FROM THE NORTH LATE WEDNESDAY. THE WAVE MODELS...WHICH WE AGREE WITH...ARE FASTER WITH THIS FEATURE. THERE IS NO SIGNIFICANT RIDGING ALOFT FOR THE COOL AIR TO BUCK... VORTICIES RISE...TENDING TO PUT CYCLONIC CURVATURE AHEAD OF THE TROUGH...SO THERE SHOULD BE NO REASON FOR THE TROUGH TO BE SLOW. SO...WE BRING THUNDERSTORMS INTO THE NORTH LATE WEDNESDAY AND MAINTAIN THEM ACROSS OUR AREA THROUGH THE NIGHT...AT THE CHANCE LEVEL...WEDNESDAY NIGHT. SPC GIVES OUR WHOLE AREA A SLIGHT RISK OF SEVERE WEDNESDAY...BUT WE NOTE THAT THE STABILITIES ARE LOWER FROM NORTH-CENTRAL MN WESTWARD. IF THE SLOWER GRID MODELS ARE CORRECT WITH THE TROUGH...THUNDERSTORMS MAY NOT REACH OUR AREA UNTIL AFTER MAXIMUM DAYTIME HEATING IS OVER...MITIGATING SEVERE WEATHER. WITH LITTLE MOISTURE AVAILABLE...WE DO NOT EXPECT MUCH RAINFALL. AFTER THE PASSAGE OF THE TROUGH...MID-RANGE MODELS INDICATE A STRONG HIGH BUILDING INTO THE AREA AND ESTABLISHING ITSELF OVER COLD LAKE SUPERIOR. RISING HEIGHTS AND A LACK OF LOW LEVEL WARM ADVECTION SUGGEST THAT THIS PATTERN CHANGE WILL INDEED OCCUR. THE FIRST SUCH HIGH BUILDS IN THURSDAY...THE GRID MODELS ARE MORE ENTHUSIASTIC ABOUT THIS AND THEY ARE USUALLY MUCH BETTER IN HANDLING THESE LAKE SUPERIOR AND HUDSON BAY SITUATIONS. A WEAK TROUGH MAY TRY TO CROSS THE AREA SATURDAY...BUT WITH HIGH HEIGHTS...HIGH AND RISING STABILITY IN THE COLUMN...AND LOW LEVEL MARITIME AIR...WE DON/T EXPECT THE TROUGH TO MAKE MUCH DIFFERENCE. ANOTHER LAKE SUPERIOR HIGH...ANCHORED BY THE UNSEASONABLY COLD WATER...SHOULD AGAIN ESTABLISH ITSELF SUNDAY. WITH THIS PATTERN...WE TENDED DRY AFTER WEDNESDAY NIGHT AND LOWERED THE TEMPERATURES...ESPECIALLY FOR AREAS ANYWHERE NEAR THE BIG LAKE WHERE THE WINDS WILL STOP TENDING TO BE FROM THE WEST AND BEGIN TO FRESHEN OUT OF THE NORTHEAST...ESPECIALLY DURING AFTERNOONS. .DLH...NONE.
