AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
334 AM CDT WED JUL 25 2007

.DISCUSSION...
VORT THAT HELPED INDUCE THE SEVERE STORMS OVER LAC QUI PARLE AND
YELLOW MEDICINE COUNTIES NOW NEAR IVANHOE AND MOVING SLOWLY SSW.
STILL SOME LIGHT RETURNS OVER PARTS OF YELLOW MEDICINE COUNTY.
THIS FEATURE HAS HAD A LONG HISTORY...BEING OVER SE MT SUNDAY
EVENING...PASSING ACROSS ND ON MONDAY AND THEN DROPPING SOUTHWARD
ACROSS WESTERN MN ON TUESDAY. WILL LET FSD AND OAX HAVE SOME FUN
WITH IT TODAY. FOG BEGINNING TO DEVELOP ACROSS THE NORTHERN AND
EASTERN CWA ATTM AND WILL CARRY SOME IN THE 12Z-14Z GRIDS THIS AM.
OVERALL...FORECAST REMAINS ON TRACK. GFS/NAM STILL IN GOOD
AGREEMENT ON THE FROPA THURSDAY NIGHT WITH HIGH PRESSURE FOR THE
WEEKEND. SEVERAL ITEMS OF INTEREST FROM NOW UNTIL THE FROPA.
FIRST...WILL BE ISSUING A HEAT ADVISORY FOR THE FAR WESTERN CWA
FOR THIS AFTERNOON. HEAT INDICES OF 105 TO 107 FORECAST. LATER
SHIFTS WILL HAVE TO KEEP AN EYE ON THE TWIN CITIES FOR HEAT
RELATED ISSUES FOR THURSDAY. CONCERN IS THAT LOW LEVEL THERMAL
RIDGE WILL BE OVER THE AREA IN THE AFTERNOON AND IF CLOUDS/SHOWERS
ARE NOT AROUND...TEMPERATURES IN THE MID 90S ARE LIKELY WITH DEW
POINTS IN THE LOWER 70S. FOR NOW...HAVE MSP FORECAST AT 93
TOMORROW WITH A DEW POINT OF 73. HEAT INDEX COMES OUT TO 103. NEXT
ISSUE REVOLVES AROUND THE UPPER LOW SPINNING OVER OH. FEATURE
STILL PROGGED BACK TO WESTERN LOWER MI BY THURSDAY MORNING. 4KM
WRF NMM SHOWING SOME SHOWER AND THUNDERSTORM ACTIVITY APPROACHING
KEAU THURSDAY MORNING FROM THE EAST. STAYED DRY THINKING ACTIVITY
WILL REMAIN JUST OFF TO THE EAST. MOST SERIOUS ISSUE IS THE
POTENTIAL FOR FLOODING THURSDAY EVENING SOMEWHERE FROM THE METRO
AREA THROUGH SOUTH CENTRAL MN AND OVER INTO WEST CENTRAL WI. GFS
PRECIPITABLE WATER VALUES NOW PROGGED AT 2.3 INCHES IN THE EVENING
WITH A 6 HOURLY INCREASE OF 0.69. WE KEEP SEEING A SIGNAL IN THE
QPF THE PAST TWO NIGHTS FOR A LARGE AMOUNT OF RAIN. 850-300MB
THICKNESS IS QUITE DIFFLUENT OVER AND TO THE SOUTH OF THE TWIN
CITIES THURSDAY EVENING. ALSO...INTERACTION BETWEEN THE RIGHT
ENTRANCE REGION OF THE JET TO OUR NORTH AND A JET SEGMENT ON THE
WEST SIDE OF THE UPPER LOW OVER MI CREATES A LARGE AREA OF
DIFFERENTIAL LAYER DIVERGENCE OVER THE EASTERN CWA. TWO CHANGES
MADE IN THE GRIDS FOR THIS SCENARIO. POPS RAISED INTO THE 60 TO
65 PERCENT RANGE AND HEAVY RAIN WORDING INSERTED. CANT RULE OUT
HAIL AND WIND THREAT AS WELL...BUT MAIN CONCERN IS THE POTENTIAL
FOR SEVERAL INCHES OF RAIN FALLING IN A SHORT AMOUNT OF TIME.
