Area forecast discussion, Jul 22, 2:17 PM CDT, 3 hours 52 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
217 PM CDT SUN JUL 22 2012

.SHORT TERM...TONIGHT THROUGH TUESDAY NIGHT...

FORECAST HIGHLIGHTS IN THE SHORT TERM PERIOD WILL BE CHANCES FOR
THUNDERSTORMS SOUTH THIS AFTERNOON/TONIGHT/MONDAY MORNING...AND
WEST INTO CENTRAL MONDAY NIGHT. MODELS IN DECENT AGREEMENT SO WILL
USE A BLEND.

CURRENTLY...SFC HIGH PRESSURE BUILDING INTO THE NORTHERN PLAINS
FROM SOUTHERN CANADA. CHANCES FOR THUNDERSTORMS WILL BE FOCUSED
ALONG A LINGERING FRONTAL BOUNDARY NEAR THE NORTH DAKOTA/SOUTH
DAKOTA BORDER AREA TODAY/TONIGHT...SUPPORTED BY A MID LEVEL S/WV
IMPULSE LIFTING ACROSS THE CENTRAL ROCKIES AND INTO THE DAKOTAS
LATE TODAY INTO THE OVERNIGHT. STRONG TO SEVERE STORMS WILL BE
POSSIBLE WITH PLENTY OF EFFECTIVE SHEAR AND MUCAPE. WHILE A FEW
OBS SITES HAVE HIT 100 HI...OVERALL TREND IS SFC DEWPOINTS
DROPPING WITH DRY AIR ADVECTION AND A NORTHWEST MIXING WIND
ACCOMPANYING PRESSURE RISES. THUS NO HEAT HEADLINES WILL BE
ISSUED.

COOLER AND DRIER FOR MONDAY WITH SURFACE HIGH PRESSURE OVER NORTH
DAKOTA. LINGERING STORMS ACROSS THE SOUTH IN THE MORNING WITH THE
AFOREMENTIONED IMPULSE ADVECTING EAST ACROSS NORTHERN SOUTH
DAKOTA. PRECIPITATION SHOULD MOSTLY DISSIPATE BY THE AFTERNOON.

NEXT CHANCE OF THUNDERSTORMS WILL MOVE INTO WESTERN NORTH DAKOTA
MONDAY NIGHT...POSSIBLY DEVELOPING INTO CENTRAL PORTIONS OF THE
STATE LATE. WILL KEEP THE HIGHER POPS WEST WITH SLIGHT CHANCES
CENTRAL.

.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY...

TUESDAY/TUESDAY NIGHT LOOK TO BE THE MOST ACTIVE PERIODS IN TERMS OF
POTENTIAL FOR SEVERE WEATHER. SPC HAS THIS HIGHLIGHTED AS WELL. THIS
IS IN TANDEM WITH AN UPPER LEVEL LOW MOVING ACROSS SOUTHERN CANADA
PROVIDING FOR LARGE SCALE ASCENT AND AN ASSOCIATED SURFACE COLD
FRONT BEING THE FOCUS FOR LOW LEVEL CONVERGENCE. MOISTURE AND
INSTABILITY WILL ALREADY BE IN PLACE. IT APPEARS THAT THE BEST
THREAT FOR SEVERE WEATHER WOULD RESIDE IN THE WEST AND FAR SOUTH
TUESDAY DURING THE DAY TUESDAY...THEN SHIFTING EAST TUESDAY NIGHT.
SHOWERS AND THUNDERSTORMS SHOULD LINGER IN THE JAMES RIVER VALLEY
THROUGH WEDNESDAY MORNING. A DRIER/COOLER/MORE STABLE NORTHWEST FLOW
DEVELOPS IN THE WEST WEDNESDAY AND SPREADS EAST WEDNESDAY AFTERNOON
INTO THURSDAY. H85 TEMPS WILL BE TRENDING DOWNWARD THROUGH THURSDAY
AND FRIDAY RANGING FROM +16C IN THE NORTH TO +20C SOUTHWEST. SURFACE
TEMPS WILL RESPOND TO THIS WITH HIGHS IN THE UPPER 70S NORTH TO MID
80S FAR SOUTH. ALTHOUGH MOST AREAS WILL BE DRY THURSDAY...THE NORTH
CENTRAL WITH STILL BE UNDER THE INFLUENCE OF THE UPPER LOW/WRAP
AROUND MOISTURE AND HAVE CONTINUED WITH A SLIGHT CHANCE OF
SHOWERS/THUNDERSTORMS. FRIDAY LOOKS TO BE A VERY NICE DAY WITH DRY
AND PLEASANT CONDITIONS. A COUPLE OF WEAK DISTURBANCES ARE THEN
FORECAST TO MOVE THROUGH SATURDAY NIGHT INTO SUNDAY PRODUCING A
SLIGHT CHANCE FOR SHOWERS/THUNDERSTORMS.

&&

.AVIATION...VFR CEILINGS AND VISIBILITIES ARE EXPECTED UNTIL 09Z
MONDAY. THEREAFTER...AN AREA OF IFR TO MVFR CEILINGS WILL MOVE INTO
KMOT BY 09Z MONDAY...AND GIVE A GLANCING BLOW OF SCT TO POSSIBLY BKN
MVFR CEILINGS AT KISN AND KJMS AFTER 09Z. DO THINK THAT KMOT WILL
RECEIVE THE BEST CHANCE FOR IFR CEILINGS WHILE SCT MVFR CEILINGS ARE
MORE LIKELY AT KISN/KJMS. IN ADDITION...AN AREA OF SHOWERS AND
THUNDERSTORMS WILL MOVE INTO SOUTHWEST NORTH DAKOTA AFTER 09Z MONDAY
AND MAINLY AFFECT KDIK. HAVE DECIDED TO USE A VCTS AT KDIK BEGINNING
AT 11Z MONDAY AND MONITOR AS THE THUNDERSTORMS DEVELOP.
