Area forecast discussion, Jun 17, 3:27 PM CDT, 5 hours 57 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
327 PM CDT SUN JUN 17 2007

.SHORT TERM...TONIGHT THROUGH WEDNESDAY NIGHT
STRONG CAPPING AND CLEARING SKIES HAVE ALLOWED CAPES TO CLIMB PAST
3000 J/KG IN THE SOUTH CENTRAL PART OF THE STATE. AN APPROACHING
SURFACE FRONT IN THE WESTERN PART OF THE STATE WILL LIKELY
GENERATE A LINE OF SEVERE THUNDERSTORMS OVER CENTRAL NORTH DAKOTA
LATER THIS AFTERNOON. MY SOUTHEASTERN COUNTIES ARE TOTALLY
SATURATED FROM RECENT RAINFALLS OF 2 TO 5 INCHES...SO ANY
THUNDERSTORM WILL POSE A FLASH FLOODING HAZARD. FOR THIS REASON I
WILL ISSUE A FLASH FLOOD WATCH FOR MY SOUTHEAST COUNTIES.

ONCE THE FRONT CLEARS MY FORECAST AREA LATER TONIGHT THE WRAP
AROUND UPPER COLD POOL MY DESTABILIZE THE POST FRONT AIRMASS ENOUGH
FOR SOME THUNDERSHOWERS MONDAY AFTERNOON.

WINDS WILL ALSO BE STIFF ON MONDAY AND A WIND ADVISORY WILL LIKELY
BE NEEDED. ILL LET THE NEXT SHIFT TAKE CARE OF THAT DETAIL.

TUESDAY AND WEDNESDAY WILL BRING AN UPPER RIDGE OVER THE NORTHERN
PLAINS...HOWEVER WEAK RIPPLES AND A TYPICAL LATE JUNE AIRMASS BEGS
A CHANCE OF THUNDERSTORMS. BUT SINCE TIMING...LOCATION AND
COVERAGE ARE IN DOUBT WILL LEAVE IT DRY FOR NOW.

.LONG TERM...THURSDAY THROUGH SUNDAY...
LONG RANGE MODELS IN GOOD OVERALL AGREEMENT. PROGRESSIVE UPPER LEVEL
FLOW PATTERN ONCE AGAIN SETTING UP OVER THE EXTENDED FORECAST
PERIOD. THE UPPER LEVEL RIDGING OVER THE NORTHERN PLAINS IS SHORT
LIVED AS ANOTHER UPPER LEVEL TROUGH MOVES INTO THE PACIFIC
NORTHWEST/NORTHERN ROCKIES. ACTIVE SOUTHWEST FLOW ALOFT OVER OUR
REGION ALONG WITH SURFACE BOUNDARIES GALORE WILL INCREASE THE
POTENTIAL FOR AN ACTIVE THUNDERSTORM PERIOD OVER THE FIRST SEVERAL
DAYS OF ASTRONOMICAL SUMMER. HAVE SLIGHT CHANCE POPS THROUGH THE
LONG TERM AS A RESULT UNTIL DETAILS BECOME MORE CLEAR.

SOUTHERLY MOISTURE AND WARM AIR ADVECTION...ALONG WITH THE
EVAPOTRANSPIRATION MOISTURE FACTOR...WILL LIKELY BRING WARM AND
HUMID DAYS THURSDAY THROUGH THE WEEKEND.

&&

.AVIATION...
A COLD FRONTAL BOUNDARY NOW LOCATED JUST EAST OF DIK AND WEST OF ISN
WILL CONTINUE TO SLIDE EAST THIS AFTERNOON AND EVENING. SCT TSRA ARE
EXPECTED TO DEVELOP AS THIS FRONTAL BOUNDARY MOVES INTO VERY
UNSTABLE AIR OVER SOUTH CENTRAL NORTH DAKOTA...THEN ADVECT EAST
EARLY THIS EVENING. SOME OF THESE STORMS WILL LIKELY BE SEVERE WITH
MVFR-IFR CIGS AND VIS. LARGE AREA OF MVFR-IFR CIGS AT 700-2000FT AGL
OVER THE NORTH IS EXPECTED TO LIFT LATER THIS EVENING BEHIND THE
FRONT. BY 00-02Z THE COLD FRONT AND ANY ASSOCIATED THUNDERSTORMS
WILL BE EAST OF THE FORECAST AREA. BEHIND THE FRONT
INITIALLY...STRONG WEST TO NORTHWEST WINDS OF 25 KNOTS OR A BIT MORE
WILL BLOW FOR 1-2 HOURS BEFORE DIMINISHING. WINDS ARE EXPECTED TO
RE-INCREASE BY TOMORROW MID-MORNING...NORTHWEST SUSTAINED AT 20-25
KTS AND GUSTS OF 30-35 KTS...AND PERSIST THROUGH MUCH OF THE DAY. IN
ADDITION FOR TOMORROW...ANOTHER SURFACE TROUGH WILL SLIDE ACROSS
SOUTH CENTRAL CANADA...WITH MVFR CIGS IN -SHRA OVER MUCH OF WEST AND
CENTRAL ND...WITH THE NORTHERN PART OF THE CWA SEEING THE BEST
CHANCE AT THIS SCENARIO.
