ON SATURDAY...ALONG WITH TEMPS IN OVERCAST/RAINY CONDITION.
PRESENTLY HAVE A STRONG COLD FRONT SURGING INTO THE FAR WESTERN
DAKOTAS FROM MONTANA THIS MORNING. BOUNDARY SHOWS UP WELL ON
REGIONAL 88D MOSAIC. WINDS BEHIND THIS FRONT ACROSS EASTERN
MONTANA HAVE BEEN EASILY EXCEEDING WIND ADVISORY CRITERIA WITH 3
HOURLY PRESSURE TENDENCIES ON THE ORDER OF 6 TO 9MB AND EXPECTING
THAT TREND TO PERSIST INTO FAR NORTHWESTERN FA DURING MORNING
HOURS. REGIONAL 88D MOSAIC ALSO DETECTING SOME ELEVATED SHRA/TSRA
RETURNS. SATELLITE IMAGERY REVEALS QUITE A SUBSTANTIAL ACCAS FIELD
HAS DEVELOPED IN THE PAST 3 HOURS ACROSS THE WESTERN DAKOTAS AND
THE NEBRASKA PANHANDLE.
BASED OFF OF COLLABORATION WITH SURROUNDING WFOS AND 55KTS RIGHT
ABOVE THE SURFACE AS DEPICTED BY ABR VAD WIND PROFILE...ELECTED TO
ISSUE A WIND ADVISORY FOR THE JAMES RIVER VALLEY AND POINTS EAST
FOR THIS MORNING THROUGH MID-DAY...AS WELL AS FOR CORSON AND DEWEY
COUNTIES OF NORTH CENTRAL SODAK IN THE POST COLD FRONTAL
NORTHWESTERLY SURFACE WINDS.
THE TIMING/PLACEMENT WOES CONTINUE BETWEEN THE GFS AND THE NAM-
WRF. CONTINUITY AND MODEL CONSENSUS LEANED ON THE GFS FOR DETAILS
FOR THIS FORECAST PACKAGE. MINOR ADJUSTMENTS MADE TO WX/POP GRIDS
DURING THE DAY ON FRIDAY TO INTRODUCE LOW END CHANCE POPS ACROSS
THE WESTERN FA ASSOCIATED WITH IMPRESSIVE BAND OF 850 TO 600HPA
FRONTOGENESIS THAT SETS UP ACROSS WESTERN/CENTRAL SOUTH DAKOTA
UNDERNEATH 60 TO 80KT UPPER LEVEL JET. ALSO ADJUSTED POPS UPWARD
FRIDAY NIGHT INTO SATURDAY ACROSS THE EASTERN FORECAST AREA WHERE
DEFORMATION ZONE SETS UP BY LATE FRIDAY NIGHT AND THEN EVOLVES
INTO TROWAL ON SATURDAY WHILE WEATHER SYSTEM UNDERGOES
CYCLOGENESIS. A QUICK LOOK AT THE 305K ISENTROPIC SURFACE /APPX
700-650HPA/ REVEALS PERSISTENT UPSLOPE FLOW PATTERN ACROSS THE
EASTERN FA IN SUPPORT OF INCREASED POPS DURING THAT TIMEFRAME.
LOW LEVEL CAA ENSUES TODAY ACROSS THE FA...SPREADING WEST TO EAST
BEHIND STRONG COLD FRONT. COOLER 850HPA TEMPS COMBINED WITH
EXPECTED PROLONGED CLOUDINESS ACROSS THE AREA FRIDAY THROUGH
SATURDAY...RESULTED IN MAX T TRENDING DOWNWARD ON SATURDAY INTO

SWINGS.
.LONG TERM...SUNDAY THROUGH WEDNESDAY
STILL SOME DIFFERENCES IN THE LONG RANGE MODEL SOLUTIONS...AND LIKE
THE PAST SEVERAL DAYS...HAVE OPTED TO STICK WITH THE GFS FOR THIS
FORECAST. A CLOSED UPPER LOW WILL BE OVER IOWA EARLY SUNDAY...WITH A
WEAKER SURFACE REFLECTION OF IT OVER IOWA AND SOUTHERN MINNESOTA.
THE UPPER LOW BEGINS TO PUSH EAST DURING THE DAY AND THE SURFACE LOW
GETS PUSHED TO THE SOUTHEAST AS HIGH PRESSURE SPREADS SOUTHWARD OVER
THE PLAINS. WILL KEEP A SMALL POP IN THE FAR EASTERN CWA SUNDAY TO
ACCOUNT FOR SOME LINGERING SHOWERS. THE SURFACE HIGH SPREADS FURTHER
SOUTHWARD ON MONDAY TO ENCOMPASS MUCH OF THE PLAINS REGION. A WESTERN
RIDGE/EASTERN TROUGH PATTERN DEVELOPS IN THE UPPER LEVELS AND
REMAINS THROUGH THE END OF THE PERIOD. THEREFORE...FROM SUNDAY NIGHT
ON LOOKS TO BE DRY.
COOLEST TEMPS OF THE PERIOD WILL OCCUR ON SUNDAY AND MONDAY IN THE
EASTERN CWA AS THAT REGION LOOKS TO REMAIN UNDER QUITE A BIT OF
CLOUD COVER ON THE WEST SIDE OF THE EXITING LOW PRESSURE SYSTEM.
SHOULD SEE MORE SUN TUESDAY AND WEDNESDAY WITH JUST SOME FAIR
WEATHER CU POSSIBLE EACH AFTERNOON IN ASSOCIATION WITH THE SURFACE
HIGH. H85 TEMPS REBOUND FROM THE SINGLE DIGITS EARLY IN THE
PERIOD...BACK TO THE MID TO UPPER TEENS FROM MONDAY AFTERNOON
THROUGH WEDNESDAY.
