AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
304 AM MDT WED JUN 11 2008

.SHORT TERM...TODAY THROUGH THURSDAY NIGHT...
MAIN UPPER LOW CENTER IS LOCATED ACROSS WEST CENTRAL MONTANA...
WITH SECONDARY SHORTWAVE ENERGY ACCELERATING EASTWARD THROUGH
CENTRAL IDAHO EARLY THIS AM. SURFACE COLD FRONT ASSOCIATED WITH
THE MAIN UPPER LOW HAS PUSHED SOUTH INTO CENTRAL COLORADO. THE
MAIN BAROCLINIC CLOUD BAND AND ASSOCIATED PRECIP...WHICH HAS BEEN
VERY SLOW MOVING OVER THE PAST 3 TO 4 HOURS...HAS SET UP FROM NE
UTAH THROUGH THE WRN DAKOTAS. THIS BAND LINES UP PRETTY WELL WITH
THE 600MB FRONT. THE FRONTAL INVERSION HAS MADE IT TO A DEPTH OF
ABOUT 10 KFT PER KCYS VAD. 3-HOUR ISALLOBARIC PRESSURE RISES ON
THE ORDER OF 4 TO 8 MB HAVE BEEN EFFICIENT IN CREATING STRONG SURFACE
WINDS EARLY THIS AM. CONTEMPLATED A WIND ADVISORY FOR THE
PANHANDLE FOR A FEW HOURS EARLY THIS MORNING...BUT WITH ONLY A FEW
SITES SURPASSING CRITERIA CURRENTLY...BEST PRESSURE RISES OVER
THEM NOW...AND WEAKENING ANTICIPATED...WILL HOLD OFF. MODELS
SUGGEST THAT BAROCLINIC BAND AND ASSOCIATED PRECIPITATION WILL
BECOME FRACTURED AND WEAKEN OVER THE NEXT 3 TO 6 HOURS AS THE
SECONDARY SHORTWAVE APPROACHES FROM THE WEST. SO...HAVE KEPT MOST
AREAS DRY THIS AM...WITH THE EXCEPTION OF NORTHERNMOST ZONES AND
THE HIGHER TERRAIN. BY THIS AFTERNOON...SLIGHTLY NEGATIVE LIFTED
INDICES AND CAPE VALUES OF AROUND 200 TO 300 J/KG BENEATH THE MID-
LEVEL THERMAL TROUGH...WILL COMBINE WITH THE SECONDARY SHORTWAVE
TO PRODUCE A FEW ISOLATED SHOWERS ACROSS THE CWA. THE DOWNSLOPE
COMPONENT WILL LIMIT COVERAGE. CONVECTION WILL LINGER THROUGH THE
EVENING...BEFORE DISSIPATING SHORTLY AFTER SUNSET. AFTERNOON HIGH
TEMPERATURES WILL BE AROUND 20 DEGREES COOLER TODAY WITH HIGHS IN
THE 50S WEST...AND 60S EAST. ANOTHER ROUND OF ISOLATED AFTERNOON
AND EVENING CONVECTION IS ANTICIPATED AGAIN ON THURSDAY...BUT
COVERAGE WILL CONTINUE TO BE LIMITED. A DRIER AIR MASS WILL BEGIN
TO MOVE IN BEGINNING THURSDAY NIGHT. A FEW DEGREES OF WARMING WILL
OCCUR ON THURSDAY...BUT TEMPERATURES WILL CONTINUE TO BE
UNSEASONABLY COOL.

.LONG TERM...FRIDAY THROUGH WEDNESDAY...
MAIN BELT OF WESTERLIES LOOKS TO RETREAT A LITTLE NORTHWARD BY
SATURDAY AS UPPER LOW LIFTS NORTHEAST OVER WESTERN ONTARIO WITH
GENERAL WNW UPPER FLOW OVER THE CWA THROUGH THE WEEKEND INTO EARLY
NEXT WEEK. EXPECT MAINLY DRY WEATHER ACROSS THE CWA AS INSTABILITY
AND BETTER MOISTURE REMAIN WELL EAST OF THE CWA THROUGH THE
WEEKEND. SOME INDICATION OF MOISTURE RETURN UP THE HIGH PLAINS
EARLY NEXT WEEK BUT UPPER RIDGING WILL BEGIN TO BUILD OVER THE
ROCKY MTNS WHICH MAY CAP CONVECTION AT LEAST TO SOME DEGREE.
TEMPERATURES WARMING UP SOME ON SATURDAY THEN NEXT COOL FRONT
EXPECTED TO PASS ACROSS SATURDAY EVENING AS SHORTWAVE SCOOTS
ACROSS THE NORTHERN ROCKIES INTO THE NORTHERN PLAINS BY SUNDAY
MORNING. SFC HIGH SETTLES OVER THE REGION SUNDAY NIGHT AND MONDAY
THEN MOVES AWAY TUESDAY ALLOWING FOR SOME RETURN FLOW.

.AVIATION...
STRONG NORTHWEST WINDS THIS MORNING...WILL TURN MORE WESTERLY AND
REMAIN STRONG THIS AFTERNOON. THIS WILL CREATE TURBULENCE IN AND
AROUND THE HIGHER TERRAIN. OTHERWISE...POCKETS OF LOWER CLOUDS AND
MVFR CIGS WILL BE POSSIBLE FOR A TIME THIS MORNING...BUT MOST
TERMINALS WILL EXPERIENCE VFR CONDITIONS. ANOTHER DISTURBANCE WILL
BRING ISOLATED SHOWERS TO THE AREA TODAY...BUT EXPECT CONDITIONS
TO CONTINUE TO BE VFR THROUGH TONIGHT.
