AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
258 AM CDT FRI SEP 14 2007

.DISCUSSION...
COLD FRONT HAS PASSED THROUGH THE REGION AND IS NOW SOUTH IN
MISSOURI. A COUPLE OF SECONDARY FRONTS REMAIN UPSTREAM IN ADVANCE OF
A LARGE AREA OF CANADIAN HIGH PRESSURE AND WILL BRING EVEN COOLER
AND DRIER AIR TO THE STATE. HIGHS TODAY WILL BE QUITE COOL WITH
HIGHS IN THE 50S AND 60S. CLOUDS OVER THE NORTH WILL HOLD READINGS
DOWN AND IF THE CLOUDS PERSIST A MAJORITY OF THE DAY...IT WILL KEEP
HIGHS BELOW FORECAST AND PAVE THE WAY FOR A HARD FREEZE TONIGHT. THE
AREA OF HIGH PRESSURE WILL BE CENTERED OVER THE STATE BY 06Z
TONIGHT. CURRENT READINGS UNDER THE SYSTEM OVER THE WRN DAKOTAS AND
MONTANA ARE IN THE UPPER 20S TO LOWER 30S. GENERALLY HAVE THESE
VALUES FOR FORECASTED LOWS BY SATURDAY MORNING FOR ALL LOCATIONS
EXCEPT THE FAR SOUTH CENTRAL AND FORECASTED RECORD LOW TEMPERATURES
FOR MOST OF THE AREA. HAVE NOT GONE QUITE AS COLD AS THE COLDEST
GUIDANCE. GUIDANCE RAN A LITTLE COLD WITH TUESDAY NIGHTS CANADIAN
HIGH AND WITH PLENTIFUL LIVE VEGETATION AND RELATIVELY WARM SOIL
TEMPERATURES THAT MAY BE THE CASE AGAIN TONIGHT. WILL BE ISSUING A
FROST ADVISORY FOR ALL COUNTIES THAT ARE HALF OR MORE COVERED WITH
FORECASTED LOWS OF 34 DEGREES OR BELOW. AN UPGRADE TO A FREEZE
WARNING IS LIKELY OVER PORTIONS OF THE NORTH BY THE DAY SHIFT...WHO
WILL HAVE A BETTER HANDLE ON TODAYS HIGHS AND CLOUD TRENDS.

STRONG WARM ADVECTION WILL COMMENCE ON SATURDAY AS THE HIGH PRESSURE
SLIDES TO THE EAST...THOUGH THIS WILL NOT TRANSLATE TO THE SURFACE
INITIALLY. THE THETA-E ADVECTION ALONG WITH THE LEFT EXIT REGION OF
THE UPPER LEVEL JET SHOULD PROVIDE ENOUGH FORCING FOR SHOWERS AND A
FEW THUNDERSTORMS OVER SOUTH CENTRAL IOWA BY SATURDAY AFTERNOON AND
EVENING WITH MORE ISOLATED ACTIVITY TO THE NORTH. HIGHS INTO THE 70S
ARE EXPECTED ON SUNDAY THOUGH THE NAM IS SUGGESTING A BROKEN LAYER
OF CLOUDS AS MOISTURE POOLS IN ADVANCE OF AN APPROACHING WARM FRONT.
IF THIS TREND CONTINUES...HIGHS MAY NEED TO BE TWEAKED DOWN. MUCH
WARMER ON MONDAY WITH HIGHS IN THE 80S AS THE WARM FRONT SLIDES TO
THE NORTH. THE NEXT CHANCE FOR UNSETTLED WEATHER IS BY TUESDAY AND
WEDNESDAY AS THE NEXT SYSTEM ARRIVES.

&&

.AVIATION...14/06Z
THE COLD FRONT IS NEARLY OUT OF CENTRAL IOWA ALONG WITH THE FRONTAL
BAND OF LOW TO MID LEVEL CLOUD COVER.  VFR DECK OVER MN MAY EDGE
INTO THE NORTHERN TAF SITES SO A TEMPO GROUP WAS ADDED FOR A BROKEN
MID LEVEL DECK.  SKC BY MORNING WITH INCREASING NW WIND AFT 12Z.
SOME GUSTINESS WILL OCCUR OVER THE TAF SITES THROUGH 20Z.
