$$What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Twin Cities, MN wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 21, 3:07 PM CDT, 1 hour 46 minutes earlier.
Area forecast discussion, Aug 21, 3:07 PM CDT, 1 hour 46 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN 307 PM CDT WED AUG 21 2013 .SYNOPSIS... ISSUED AT 305 PM CDT WED AUG 21 2013 EARLY AFTERNOON WATER VAPOR IMAGERY TOGETHER WITH THE GFS 21.12 500MB HEIGHTS AND WINDS SHOWED AN AREA OF ZONAL FLOW ALONG THE INTERNATIONAL BORDER ON THE POLEWARD SIDE OF THE MONSOONAL RIDGE WHICH WAS SANDWICHED BETWEEN TWO CUTOFF LOWS. THE EASTERN LOW LOCATED OVER THE OHIO RIVER VALLEY WAS BECOMING MORE OF A PROGRESSIVE OPEN WAVE...WHILE THE WESTERN LOW WAS SPINNING UP THE CALIFORNIA COAST. && .SHORT TERM...(THIS EVENING THROUGH THURSDAY) ISSUED AT 305 PM CDT WED AUG 21 2013 A COLD FRONT WILL DRIFT EAST AND SOUTH OF THE CWA THIS EVENING WITH MUCH DRIER AIR SPREADING IN FOR THURSDAY. THE FRONT WILL LIKELY HANG UP FOR A TIME LATE TONIGHT AND EARLY THURSDAY JUST SOUTH OF MN AS A WEAK WAVE OF LOW PRESSURE MOVES EASTWARD ALONG THE FRONT. THEREFORE... KEPT SOME SMALL POPS OVERNIGHT AND EARLY THURSDAY MORNING ALONG I-90. HAVING SOME POPS IN ACROSS THE FAR SOUTH OVER NIGHT RESULTED IN MORE CLOUDINESS IN THE GRIDS ALONG WITH LOW TEMPERATURES A FEW DEGREES HIGHER IN THE FAR SOUTH. CONDITIONS OVERNIGHT WILL BE MUCH DIFFERENT ACROSS CENTRAL MN AND ADJOINING AREAS OF WEST CENTRAL WI WHERE DEW POINTS ARE FORECAST TO REACH INTO THE MIDDLE 40S WITH LOW TEMPERATURES IN THE LOWER TO MIDDLE 50S. OTHER THAN THE SMALL CHANCE FOR PRECIPITATION IN THE FAR SOUTH EARLY ON THURSDAY... A VERY PLEASANT DAY IS IN STORE AS HIGH PRESSURE BUILDS OVER THE REGION. VERY DRY AIR IS INDICATED WITH LOWER TO MIDDLE 40 DEGREE DEW POINTS COVERING CENTRAL MN...THE TWIN CITIES AND WEST CENTRAL WI BY MID AFTERNOON. USED SEVERAL BIAS CORRECTED GUIDANCE PRODUCTS FOR THE HIGH TEMPERATURE ON THURSDAY... WHICH PUSHED HIGHS UP A FEW DEGREES WITH AROUND 80 TO THE LOWER 80S EXPECTED. AFTERNOON HUMIDITY LEVELS SHOULD DROP INTO THE 25 TO 30 PERCENT RANGE ALONG AND NORTH OF THE I-94 CORRIDOR WITH 30 TO 40 PERCENT TO THE SOUTH. .LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY) ISSUED AT 305 PM CDT WED AUG 21 2013 AT THE START OF THE PERIOD THE COLD FRONT THAT PUSHED THROUGH THE REGION ON WEDNESDAY WILL HAVE PROGRESSED SOUTHWARD ACROSS IOWA...AND THIS WILL BE THE FOCUS FOR LINGERING THUNDERSTORMS THURSDAY EVENING. KEPT MN/WI DRY THURSDAY NIGHT AND FRIDAY WITH THE MAIN FORCING FOR PRECIP CONFINED TO THE SOUTH ALONG THE BOUNDARY. BY FRIDAY NIGHT THE FRONTAL BOUNDARY WILL LIFT NORTHWARD AS A WARM FRONT...AND H850 THETA_E ADVECTION WILL SPREAD ACROSS THE UPPER MIDWEST AND BE THE FOCUS FOR NOCTURNAL CONVECTION IN CONCERT WITH A WEAK H500 SHORTWAVE THAT IS PROGGED TO RIDE THE PERIPHERY OF THE MONSOONAL RIDGE AND MOVE ACROSS THE DAKOTAS FRIDAY NIGHT. H925 WINDS AND MOISTURE TRANSPORT OF THE NAM12 21.12 SHOW A 40KT LOW LEVEL JET...WITH 500 GM/KGS OF MOISTURE TRANSPORT. THESE HIGH VALUES ARE SUPPORTED BY THE GFS 21.12...WHICH HAS 35KTS AND 450 GM/KGS. IN ADDITION...PWATS WILL INCREASE TO 1.5 - 1.9 INCHES. HOWEVER...AS THE EVENING PROGRESSES THE THERMAL GRADIENT BECOMES INCREASINGLY PARALLEL WITH THE SOUTH SOUTHWESTERLY WINDS. IN ADDITION NOSE OF THE H925 JET IS IN SOUTHERN CANADA. WITHOUT LOW LEVEL CONVERGENCE OR ISENTROPIC ASCENT IT WILL BE DIFFICULT TO GET DEEP CONVECTION SOUTH OF A LINE FROM MADISON...THROUGH MINNEAPOLIS...AND EAU CLAIRE. INSTEAD THE WARM AIR ADVECTION WILL LIKELY JUST ESTABLISH A CAPPING INVERSION THAT WILL SUPPRESS CONVECTION AND BRING NEAR RECORD HEAT FOR NEXT WEEK. ON SATURDAY H850 TEMPS OF 20+C SPREAD ACROSS THE REGION AND LINGER THROUGH THE END OF THE FORECAST PERIOD IN CONJUNCTURE WITH 500MB 590DM HEIGHTS. BOTH THE GFS/GEM/ECMWF 21.12 BRING ANOTHER SHORTWAVE AROUND THE RIDGE AXIS ON SUNDAY...AND AGAIN ON TUESDAY...BUT THESE SHOULD BE NORTH OF THE CWA. THEREFORE HAVE TRIMMED OF POPS ACROSS THE SOUTH AS THE STRETCH OF DRY WEATHER WILL CONTINUE. PROVIDED THAT THE CONVECTION DOES REMAIN TO THE NORTH...THE THERMAL PARAMETERS DESCRIBED ABOVE WILL PROMOTE SURFACE TEMPS IN THE LOW TO MID 90S THROUGH THE MIDDLE OF NEXT WEEK. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z THURSDAY AFTERNOON) ISSUED AT 120 PM CDT WED AUG 21 2013 PRIMARY CONCERNS FOR THIS ISSUANCE ARE THE CHANCE FOR THUNDERSTORMS...AND THE CHANGING WIND DIRECTION ASSOCIATED WITH THE COLD FRONT CURRENTLY MOVING ACROSS THE FA. LOW LEVEL MOISTURE WILL ALSO IMPACT CEILINGS THIS AFTERNOON ALONG AND BEHIND THE FRONT. WINDS HAVE ALREADY TURNED QUICKLY NORTH NORTH AND WEST OF THE METRO AREA...AND THE THUNDERSTORM CHANCES THERE HAVE DIMINISHED. THIS AREA WILL CONTEND WITH MVFR CIGS FOR THE NEXT FEW HOURS. TO THE SOUTH AND EAST OF THE METRO...SCATTERED THUNDERSTORMS WILL CONTINUE...WITH EAU CLAIRE HAVING THE BEST CHANCE TO SEE THUNDERSTORMS LATER THIS AFTERNOON. BY TONIGHT...THE FRONT WILL CLEAR THE AREA AND WINDS WILL ALL TURN TO MORE OF A NORTHERLY FLOW...BEFORE NORTHEAST BY TOMORROW. DEW POINT TEMPERATURES WILL SIGNIFICANTLY LOWER TONIGHT WHICH WILL THWART FOG CHANCES ACROSS THE AREA. KMSP...FRONT IS CLEARING THE AIRFIELD AT THIS TIME...SO THE WIND WILL SHIFT QUICKLY TO NORTHWEST WITHIN AN HOUR TWO...AND CONTINUE TO TURN THIS EVENING TO NORTH...THEN NORTHEAST BY THE OVERNIGHT HOURS. MVFR CIGS WILL CONTINUE FOR A SHORT TIME THIS AFTERNOON...BUT THUNDER CHANCES HAVE REALLY DIMINISHED AND THE AIRFIELD WILL LIKELY NOT SEE ANY THUNDER. VFR CONDITIONS WILL PREVAIL THROUGH TOMORROW ONCE THE MVFR CIGS MOVE ON THIS AFTERNOON. /OUTLOOK FOR KMSP/ THU...VFR. NE WIND 5 KTS. FRI...VFR. SCHC OF SHRA/TSRA. SE WIND 5 TO 10 KTS. SAT...VFR.
