AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
302 PM CDT THU AUG 14 2008

.DISCUSSION...
UPPER LEVEL LOW ACROSS EASTERN MONTANA THURSDAY AFTERNOON IS
EXPECTED TO DIVE TO THE SOUTH AND WEST OVERNIGHT. BEST CHANCES FOR
LATE AFTERNOON AND EVENING THUNDERSTORMS APPEARS TO BE WEST OF I-29.
AS THE EVENING WEARS ON...EXPECT THUNDERSTORMS TO DECREASE IN AREAL
COVERAGE...THOUGH A FEW LIGHT SHOWERS COULD CONTINUE WEST OF THE
JAMES RIVER VALLEY OVERNIGHT DUE TO WARM AIR ADVECTION ALOFT.
INSTABILITY THIS EVENING APPEARS TO BE SOMEWHAT LIMITED...SO ANY
SEVERE THREAT WOULD BE VERY ISOLATED IN NATURE. FLOW SHOULD BE
RELATIVELY WEAK...BUT PREDOMINANT NORTHEAST WINDS SHOULD DRAW DRIER
AIR INTO THE REGION.  HAVE SIDED WITH LOWS IN THE MID AND UPPER 50S
ACROSS SOUTHWEST MINNESOTA/NORTHWEST IOWA...WHILE AREA FURTHER TO
THE WEST REMAIN IN THE LOWER 60S DUE TO CLOUD COVER.

FOR FRIDAY...MODELS STILL TRENDING UPPER LEVEL SUPPORT FARTHER SOUTH
WITH DRY AIR INTRUDING FROM THE EAST AND NORTHEAST. WITHOUT MUCH
INSTABILITY...THE LOSS OF MOISTURE WILL TAKE THE CHANCE FOR
RAINFALL FARTHER SOUTH. SO WENT AHEAD AND INCLUDED LOW POPS FOR JUST
THE SOUTHWESTERN QUARTER OF THE CWA AND BY FRIDAY NIGHT JUST GOING
WITH AN ISOLATED POTENTIAL OVER THE FAR SOUTH. HIGHS ON FRIDAY WILL
BE VERY NICE...RANGING FROM THE MID 70S TO LOWER 80S. WITH THE DRY
AIR AND WEAK FLOW IN FRIDAY NIGHT MOST LOCATIONS WILL FALL INTO THE
50S.

THE WEEKEND LOOKS LIKE IT SHOULD STAY DRY AS COOL AND STABLE AIR
REMAINS IN PLACE AND ANY UPPER LEVEL SUPPORT REMAINS TO THE
SOUTHWEST OF THE AREA. THE MODELS ARE HINTING AT A FEW WEAK IMPULSES
DROPPING THROUGH MAINLY SW MN SATURDAY SO AN ISOLATED SHOWER NOT
COMPLETELY OUT OF THE QUESTION...BUT COVERAGE SHOULD BE LOW.
TEMPERATURES WILL MODERATE CLOSER TO NORMAL WITH LOWS MAINLY IN THE
50S TO LOW 60S AND HIGHS FROM THE UPPER 70S TO UPPER 80S.

IN THE LATTER PERIODS(MON-THU)...MAIN CHALLENGE WILL BE FIGURING OUT
JUST WHERE THE UPPER LOW WILL END UP. THE 0Z AND 6Z GFS AS WELL AS
THE 0Z ECMWF AND 0Z GFS ENSEMBLE ALL IN PRETTY GOOD AGREEMENT TODAY
ON TAKING UPPER LOW INTO KS ON MONDAY...THEN FASTER FLOW DEVELOPS
ACROSS THE NORTHWEST U.S. AND SHOULD AID IN LIFTING THIS LOW TO THE
NORTH TUESDAY INTO WEDNESDAY. THESE TWO DAYS SHOULD PROVE TO BE OUR
BETTER CHANCES FOR RAIN AND THUNDERSTORMS...BUT THE CHANCES COULD
CONTINUE THROUGH THE END OF THE WEEK AS POTENTIALLY MUCH MORE
UNSTABLE AIR SETS UP THURSDAY AND A RELATIVELY STRONG WAVE MOVES
INTO THE NORTHERN PLAINS THURSDAY NIGHT INTO FRIDAY. TOO FAR OUT TO
GET EXCITED ABOUT BUT COULD END UP WITH A DECENT PATTERN FOR SEVERE
WEATHER LATE IN THE WEEK.

&&

.AVIATION...
SCATTERED THUNDERSTORMS ARE EXPECTED MAINLY ALONG AND WEST OF I-29
THIS EVENING.  VISIBILITIES WITHIN THE THUNDERSTORMS MAY BRIEFLY
FALL BELOW 5SM...OTHERWISE VFR CONDITIONS ARE EXPECTED TO PREVAIL AS
HIGH PRESSURE BUILDS INTO THE UPPER MIDWEST.

&&

.FSD WATCHES/WARNINGS/ADVISORIES...

SD...NONE.
MN...NONE.
IA...NONE.
NE...NONE.
