NWS Twin Cities, MN wrote its last area forecast discussion before the first event at Aug 12, 2:11 PM CST, 5 hours 14 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN 311 PM CDT SAT AUG 12 2006 .DISCUSSION... IN THE SHORT TERM...TONIGHT THROUGH TUESDAY 12Z WATER VAPOR SUGGESTED THAT THE INITIALIZATION OF THE 500 MB TROUGH IN THE PACIFIC NORTHWEST WAS TOO FAR EAST ON THE NAM...CLOSER TO THE 12Z GFS INITIALIZATION. ESSENTIALLY BIASED FORECAST TOWARD THE GFS FOR THE ENTIRE SHORT TERM PACKAGE. THAT HAVING BEEN SAID...USED THICKNESS DIFFLUENCE FROM THE NAM AND GFS FOR TIMING MOST SIGNIFICANT PRECIPITATION TONIGHT INTO SUNDAY NIGHT. ALSO...GAVE A LOT OF CONSIDERATION TO THE SREF PROBABILITY OF GREATER THAN .25 INCH IN A 6 HOUR PERIOD. IN THE TONIGHT PERIOD...THERE IS AN AREA OF 850 MB THETA E ADVECTION ACROSS MUCH OF THE MN PORTION OF THE CWA...ERGO THE POPS...THOUGH SMALLER THAN THOSE TO THE NORTHWEST. NAM AND GFS SOUNDINGS VIEWED IN BUFKIT DEPICTED LONG SKINNY CAPES...A HEAVY RAIN SIGNAL...ACROSS WEST CENTRAL MN TONIGHT INTO SUNDAY MORNING. THE PRESENCE OF THE SUBTROPICAL MOISTURE PLUME FURTHER SUGGESTS ONLY MODEST ELEVATED INSTABILITY BUT AN ABUNDANCE OF MOISTURE...INDEED PRECIPITATABLE WATER VALUES EXCEED 150 PERCENT OF NORMAL MOST AREAS TONIGHT INTO SUNDAY. SO DID MENTION HEAVY RAIN IN WEST CENTRAL MN. HOWEVER...THE 3 HOURLY FLASH FLOOD GUIDANCE FOR THIS DROUGHTY PART OF MN IS CLOSE TO 4 INCHES...AND THE SOIL TYPE IS SANDY LOAM ACCORDING TO OUR NEIGHBORING RFC...THEREFORE HELD OFF ON A FLASH FLOOD WATCH. MAIN CONCERN WOULD BE IF EXCESSIVE RAINFALL RATES OCCUR OVER THE URBAN AREAS OF WEST CENTRAL MN. OF COURSE...THE NUMBER OF URBAN AREAS IN WEST CENTRAL MN IS SMALL. WITH THE PASSAGE OF THE UPPER TROUGH BY 12Z MONDAY...THE DRY WEATHER RETURNS FOR MONDAY THROUGH TUESDAY. LOWERED MAXIMUM TEMPERATURE FORECASTS FOR SUNDAY AND MONDAY BASED ON A MIX OF MOS NUMBERS. ALSO...CLOUDS ON SUNDAY...AND COOLER TEMPERATURES ALOFT MONDAY...SHOULD SUPPORT THESE LOWER HIGHS. LONGER TERM...TUESDAY TONIGHT THROUGH SATURDAY FIRST HALF OF EXTENDED LOOKS ON TRACK WITH FLUSHING OF MOISTURE AND CLOUDS AND A PERIOD OF NICE WEATHER THROUGH WEDNESDAY. SYNOPTIC PATTERN SUGGESTS RETURN FLOW ON BACKSIDE OF RIDGE ON WEDNESDAY EVENING PROMPTING CHANCE FOR SHOWERS DEVELOPING OVERNIGHT. TIMING OF TSTMS BEYOND THURSDAY IS RISKY AND CHOSE NOT TO REMOVE POP CHANCES FOR FRI. COULD BE A FRONT STALLED OVER CWA AT THE END OF THE WEEK AS MODELS IN GENERAL AGREEMENT ABOUT NEARLY ZONAL FLOW OVER UPPER MIDWEST. NO REASON TO FUSS WITH TEMPERATURES AT END OF FORECAST PERIOD AS THEY ARE CLOSE TO SEASONAL VALUES. && .MPX WATCHES/WARNINGS/ADVISORIES... MN...NONE. WI...NONE. && NAISTAT/CME
