AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
327 AM MDT SUN MAR 25 2012

.SHORT TERM...TODAY THROUGH TUESDAY NIGHT...
DRY AND WARMER WEATHER EXPECTED TODAY AS HEIGHTS RISE A BIT AHEAD
OF UPPER LOW NOW OFF THE CALIFORNIA COAST. WEAK SFC FRONT ALONG
THE MTNS MAY RETREAT A BIT EAST TODAY BUT NOT MUCH AS SFC
PRESSURES FALL OVER THE HIGH PLAINS LATER TODAY IN ADVANCE OF
UPPER SYSTEM NEARING THE WEST COAST. RAPIDLY CHANGING CONDITIONS
ON THE WAY FOR MONDAY AS UPPER SYSTEM MOVES ONSHORE OVER
CALIFORNIA THIS EVENING THEN EJECTS QUICKLY NORTHEAST MONDAY...
REACHING THE NORTHERN PLAINS MONDAY EVENING. STRONG WINDS EXPECTED
INITIALLY OVER THE WESTERN LOWER ELEVATIONS OF THE CWA AHEAD OF
THIS SYSTEM BY MONDAY AFTERNOON THEN SPREADING EAST INTO THE
EASTERN PLAINS LATE MONDAY AFTERNOON INTO THE EARLY EVENING HOURS
BEHIND A STRONG PACIFIC COLD FRONT THAT WILL SWEEP ACROSS THE
AREA. A RATHER SHORT PERIOD OF HIGH WINDS LOOKS A DECENT BET OVER
MANY AREAS MONDAY AFTERNOON INTO THE EARLY EVENING INITIALLY AS
STRONG SW FLOW AHEAD OF THE FRONT OVER THE WESTERN CWA THEN
TRANSITIONING TO A BORA TYPE EVENT OVER THE EASTERN PLAINS LATER
MONDAY AFTERNOON INTO THE EARLY EVENING HOURS. HAVE POSTED HIGH
WIND WATCHES DUE TO THIS POSSIBILITY. PCPN WILL BE RATHER SPARSE
WITH THIS SYSTEM AS MOISTURE AND INSTABILITY WILL BE LIMITED BUT A
FEW WEAK STORM POSSIBLE OVER THE NORTH PART OF THE CWA MONDAY LATE
AFTERNOON AS GOOD DYNAMICAL FORCING ZIPS NORTHEAST OVER THAT AREA
WITH SOME SHOWERS OVER WESTERN PARTS OF THE CWA. CLEARING OUT
MONDAY EVENING AS UPPER SYSTEM EJECTS NORTHEAST WITH DRY AND
COOLER CONDITIONS FOR TUESDAY AND TUESDAY NIGHT.

.LONG TERM...WEDNESDAY THROUGH SUNDAY...
CRITICAL FIRE WEATHER CONDITIONS WILL BE THE PRIMARY CONCERN FOR
THE LATTER HALF OF THE UPCOMING WEEK AS THE UNSEASONABLY WARM
TEMPERATURES AND DRY CONDITIONS PERSIST. INITIALLY...TRANSITORY
RIDGING EMBEDDED WITHIN SOUTHWEST FLOW WILL MOVE OVER THE CWA ON
WEDNESDAY. ALTHOUGH MINIMUM RELATIVE HUMIDITIES WILL DROP TO
CRITICAL THRESHOLDS...PEAK WINDS WITHIN THE BOUNDARY LAYER THAT
MIXES TO AROUND H6 WILL ONLY BE AROUND 18 KNOTS OUT ON THE
CRITICALLY FUELED EASTERN PLAINS. STRONGER WINDS WILL BE AVAILABLE
WEST OF THE LARAMIE RANGE...SO IF FUELS ARE FLIPPED TO CRITICAL
THERE WOULD NEED A HILITE. MUCH OF THE SAME ON THURSDAY WITH DRY
CONDITIONS CONTINUING. WINDS WILL EXPAND EASTWARD AND BE STRONGER
ON THURSDAY AND STILL EXPECT CRITICALLY LOW RELATIVE HUMIDITIES TO
BE IN PLACE. MEDIUM RANGE DETERMINISTIC MODELS BEGIN TO DIVERGE
ON FRIDAY...WITH THE 25/00Z OPERATIONAL ECMWF THE OUTLIER. IT
PROGS A STRONG TROUGH DIGGING INTO THE CENTRAL PLAINS...EVENTUALLY
CLOSING OFF NR KC LATE FRIDAY. NO OTHER MODEL SUPPORTS THIS
SOLUTION...SO FAVORED THE 25/00Z GFS ENSEMBLE AND 24/12Z ECMWF PER
THE HPC EXTENDED DISCUSSION. THIS WILL SET THE STAGE FOR THE
CONTINUED BREEZY TO LOCALLY WINDY...WARM AND DRY CONDITIONS AGAIN
ON FRIDAY AND SATURDAY. SO...WILL NEED TO BE CONCERNED WITH
CRITICAL FIRE CONDITIONS BOTH DAYS. FOR SUNDAY...FLOW WILL
AMPLIFY AS IT BACKS TO THE SOUTHWEST AHEAD OF AN UPPER TROUGH THAT
WILL MOVE INTO THE NORTHERN ROCKIES. FOR NOW...HAVE INTRODUCED
PRECIPITATION CHANCES FOR MAINLY FOR AREAS ALONG AND WEST OF THE
LARAMIE RANGE ON SUNDAY.

&&

.AVIATION...06Z TAF ISSUANCE...
VFR CONDITIONS FOR OUR SOUTHEAST WYOMING AIRPORTS. OF MORE CONCERN
WILL BE HOW THE EASTERLY WINDS WILL IMPACT OUR NEBRASKA PANHANDLE
AIRPORTS EARLY SUNDAY MORNING. MODEL SOUNDINGS SHOWING A MOIST
LOW LEVEL TOWARDS 10Z CONDUCIVE TO FOG/LOW STRATUS DEVELOPMENT.
HAVE ADDED A PERIOD OF IFR/MVFR CONDITIONS IN FOG TO THE WESTERN
NEBRASKA AIRFIELDS AS A RESULT. THIS FOG AND LOW STRATUS SHOULD
BEGIN TO BURN OFF BY AROUND MID-MORNING ON SUNDAY. WINDS WILL
BECOME BREEZY WITH GUSTS OF 20 TO 30 KNOTS AT MOST TERMINALS BY
THIS AFTERNOON.

&&

.FIRE WEATHER...
CRITICAL CONDITIONS SHOULD OCCUR IN A FEW AREAS OF SOUTHEAST WY
THIS AFTERNOON AS MARGINAL WINDS COMBINE WITH LOW AFTERNOON RHS TO
PRODUCE SOME LOCALIZED RED FLAG CONDITIONS. MUCH MORE SIGNIFICANT
EVENT FOR MONDAY AFTERNOON AS POTENT UPPER SYSTEM MOVES QUICKLY
ACROSS THE AREA AND BRINGS STRONG WINDS FOR A TIME. STRONG PACIFIC
COOL FRONT WILL SWEEP ACROSS THE DISTRICTS MONDAY AFTERNOON AND
COMBINED WITH LOW RHS WILL PRODUCE VERY CRITICAL CONDITIONS
ESPECIALLY OVER THE PLAINS. COOLER WITH LESS WIND TUESDAY.
