AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
340 AM CDT WED AUG 20 2008

.SHORT TERM...TODAY THROUGH FRIDAY NIGHT...
FORECAST CONCERNS/HIGHLIGHTS IN THE SHORT TERM PERIOD WILL FIRST
FOCUS ON WARM TEMPERATURES EXPECTED AGAIN TODAY AND THURSDAY...THEN
A BIG COOL DOWN FOR FRIDAY. ALSO CONTINUED WINDY TODAY AND THURSDAY
MAINLY SOUTH CENTRAL AND EAST...THEN GUSTY WESTERLY WINDS DEVELOPING
THURSDAY NIGHT INTO FRIDAY AREA WIDE. ATTENTION THEN SHIFTS TOWARDS
OUR CONVECTIVE CHANCES STARTING OUT LATER TODAY WEST AND CONTINUING
TONIGHT THROUGH THURSDAY NIGHT...AND PERHAPS INTO FRIDAY DAYTIME.
DETAILS BELOW. MODELS ARE GENERALLY IN PRETTY DECENT AGREEMENT SO
WILL ONCE AGAIN UTILIZE A BLEND WITH A FEW TWEAKS HERE AND THERE.

CURRENTLY...AN UPPER LEVEL S/WV TROUGH IS LIFTING NORTHEAST ACROSS
WESTERN MONTANA AND INTO ALBERTA AHEAD OF A SIGNIFICANT UPPER LEVEL
LOW NOW OFF THE BRITISH COLUMBIA COAST. A LEE SIDE SURFACE TROUGH
REMAINS OFF TO OUR WEST ACROSS THE NORTHERN HIGH PLAINS OF MONTANA
AND SASKATCHEWAN. AS A RESULT THE PRESSURE GRADIENT REMAINS TIGHT
ACROSS THE DAKOTAS WITH SOUTHEASTERLY WINDS AROUND 15 TO 25 MPH THIS
EARLY MORNING AT MOST OBSERVING SITES. MOSTLY CLEAR WEST AND PARTLY
CLOUDY CENTRAL AND EAST AS SOME MID LEVEL CLOUDS ARE DEVELOPING DUE
TO A STRONG NOCTURNAL LOW LEVEL JET STRETCHED ACROSS THE CENTRAL
DAKOTAS.

ANOTHER WARM AND BREEZY DAY TODAY AS THE SFC TROUGH IS SLOW
TO MOVE EAST AND CONTINUES TO STRENGTHEN...CONSTRICTING THE PRESSURE
GRADIENT EVEN MORE ACROSS THE CENTRAL DAKOTAS. THUS EXPECTING
STRONGER WINDS LATER THIS MORNING AND AFTERNOON SOUTH CENTRAL AND
EAST BUT MUCH LIGHTER WEST DUE TO THE POSITION OF THE SFC TROUGH
ALONG THE NORTH DAKOTA/MONTANA BORDER. THIS WILL HELP ALLEVIATE FIRE
WEATHER CONCERNS FOR TODAY WITH NO HEADLINES NEEDED AS OUR LOWEST
PERCENT RH VALUES WILL COINCIDE WITH WINDS 5 TO 15 MPH. HAVE
INTRODUCED SLIGHT CHANCES OF LATE AFTERNOON THUNDERSTORMS WEST
CENTRAL AND NORTHWEST AS 700MB CAA LOOKS TO WEAKEN THE CAP HERE. THE
SURFACE TROUGH AXIS ALSO IN THE SAME GENERAL VICINITY AND SHOULD
HAVE NO PROBLEM REACHING CONVECTIVE TEMPS LATER IN THE DAY. ANY RATE
THOUGHT AT LEAST SLIGHT CHANCE POPS ARE WARRANTED.

AS MENTIONED...STRONGEST WINDS WILL BE LOCATED SOUTH CENTRAL AND
SOUTHEAST LATER THIS MORNING AND AFTERNOON...AND WILL BE SUSTAINED
AROUND 25 TO 30 MPH WITH A FEW GUSTS BETWEEN 35-40 MPH POSSIBLE.
THUS FELT IT PRUDENT TO GO WITH A WIND ADVISORY HERE FROM 15Z THIS
MORNING UNTIL 01Z THIS EVENING.

CONVECTIVE CHANCES CONTINUE TONIGHT MAINLY WEST AND NORTH CENTRAL AS
THE SFC TROUGH SLOWLY MOVES INTO FAR WESTERN ND...AND WHERE FLOW
ALOFT TRANSITIONS TO MORE SOUTHWESTERLY AND BEST 0-6KM SHEAR
RESIDES. HOWEVER...ANOTHER STRONG NOCTURNAL LOW LEVEL JET DEVELOPS
AGAIN TONIGHT ACROSS NORTH AND SOUTH DAKOTA...THIS TIME WITH
MUCAPE VALUES OF AROUND 400 J/KG IN PLACE (LITTLE TO NO ELEVATED
CAPE PRESENT CURRENTLY). HAVE BEEN BURNED BEFORE UNDER THIS
SCENARIO SO WILL THROW IN ISOLD THUNDER CHANCES ACROSS THE
MAJORITY OF THE CWA FOR TONIGHT.

YET ANOTHER DAY OF WARM AND WINDY CONDITIONS ON THURSDAY (TEMPS IN
THE 90S AND STRONG SOUTHERLY WINDS SOUTH CENTRAL AND EAST) AS THE
SURFACE TROUGH SLOWLY INCHES EASTWARD ACROSS THE WESTERN DAKOTAS.
ANOTHER WIND ADVISORY WILL LIKELY BE NEEDED. KEPT SLIGHT CHANCE
POPS THURSDAY DAYTIME ALONG AND BEHIND THE TROUGH AXIS/SFC COLD
FRONT (WEST AND NORTH CENTRAL) AS WE LOOK TO BE STRONGLY CAPPED IN
THE WARM SECTOR (SOUTH CENTRAL AND SOUTHEAST). THE STRONG CLOSED
UPPER LOW MOVES INTO SOUTHERN SASKATCHEWAN AND NORTHEASTERN
MONTANA LATER THURSDAY EVENING...EJECTING THE SFC TROUGH EASTWARD
AND PUSHING A STRONG COLD FRONT WEST TO EAST ACROSS NORTH DAKOTA
THROUGH THE OVERNIGHT HOURS. KEPT HIGHEST POPS NORTHWEST AND NORTH
CENTRAL THURSDAY NIGHT WHERE THE GREATEST MID/UPPER LEVEL DYNAMICS
OF THE CLOSED UPPER LOW WILL TRACK. STRONG TO SEVERE CONVECTION IS
VERY POSSIBLE BUT WILL AGAIN HOLD OFF ON MENTIONING THIS WITHIN
THE ZFP AND CONTINUE TO STRONGLY WORD IN THE HWO.

CONTINUED CHANCES OF PRECIPITATION FRIDAY DAYTIME AS THE UPPER LOW
TRACKS ACROSS SOUTH CENTRAL CANADA...BUT THE MAIN STORY WILL BE THE
AFFECTS OF THE STRONG COLD FROPA FROM THURS NIGHT. MUCH COOLER WITH
HIGHS MAINLY IN THE 70S ON FRIDAY BEHIND THE STRONG COLD
FRONT...ALONG WITH GUSTY WESTERLY WINDS ACROSS MUCH OF THE FORECAST
AREA (THESE WINDS ALREADY DEVELOP ACROSS THE WEST THURSDAY NIGHT). A
WIND ADVISORY AGAIN LOOKS LIKELY WITH PEAK GUSTS EXPECTED TO BE UP
TO AROUND 35 - 40 MPH...THIS TIME ENCOMPASSING THE MAJORITY OF
WEST AND CENTRAL ND.

.LONG TERM...SATURDAY THROUGH WEDNESDAY...
RIDGING DEVELOPS SATURDAY THROUGH MONDAY WITH A WARMING TREND AND
DRY WEATHER. H85 TEMPS PEAK ON MONDAY CONSEQUENTLY GIVING HIGH
TEMPERATURES AROUND 90/LOWER 90S OVER MOST OF OUR CENTRAL AND
WESTERN FORECAST REGION. A COLD FRONT WILL MOVE THROUGH THE AREA ON
TUESDAY CREATING A SLIGHT CHC OF SHWRS/TSTMS. PATTERN BECOMES
ZONAL/COOLER BEHIND THIS SYSTEM WEDNESDAY WITH ANOTHER UPPER TROUGH
TO PASS THROUGH LATER IN THE WEEK.

&&

.AVIATION...VFR CONDITIONS CONTINUE TODAY. AFTER 21Z...KISN/KDIK
STAND THE RISK OF AN ISOLATED SHOWER/THUNDERSTORM. WITH CLOUD BASES
FAIRLY HIGH UP AROUND 10KFT TO 12KFT INITIALLY...WOULD ANTICIPATE
STRONG DOWNDRAFT WINDS ASSOCIATED WITH EVAPORATIVE COOLING BENEATH
THE CLOUD BASE...AT LEAST UNTIL THE CLOUD BASES LOWER TO AROUND
8KFT. ISOLATED GUSTS COULD REACH 50KT OR MORE UNDER THE STRONGEST
DOWNDRAFT. ELSEWHERE...WINDY SOUTH WINDS OF 20 TO 35 MPH WILL
COMMENCE TODAY UNDER MOSTLY SUNNY CONDITIONS. STRONGEST WINDS WILL
BE BETWEEN KBIS AND KJMS AND AREAS SOUTH.

&&

.BIS WATCHES/WARNINGS/ADVISORIES...
WIND ADVISORY FROM 10 AM THIS MORNING TO 8 PM CDT THIS EVENING
FOR NDZ022-023-025-035>037-046>048-050-051.
