AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
226 AM MST THU NOV 13 2014
.SHORT TERM...(TODAY THROUGH SATURDAY NIGHT)
ISSUED AT 300 AM MST THU NOV 13 2014
FORECAST CHALLENGES DEAL WITH TEMPERATURES AS ARCTIC AIR REMAINS
IN PLACE...FOLLOWED BY WINDS FRIDAY AND SNOW CHANCES SATURDAY.
CURRENTLY...1044MB SURFACE HIGH OVER CENTRAL WYOMING THIS MORNING.
CLEAR SKIES AND SNOWPACK IN PLACE HAS CREATED VERY COLD
TEMPERATURES. IN FACT...LARAMIE HAS ALREADY BROKEN ITS RECORD LOW
TEMPERATURE OF -14F THIS MORNING. ALLIANCE BROKE THEIR RECORD LOW
OF -9F FOR THIS MORNING AS WELL. GOOD NEWS...WINDS ARE NOT AS
STRONG THIS MORNING WITH THE HIGH OVERHEAD...SO WIND CHILLS ARE
NOT AS BAD AS THEY COULD HAVE BEEN. GENERALLY SEEING -15 TO -25F
AROUND THE AREA...SO WIND CHILL ADVISORY IS PANNING OUT WELL.
START TO SEE WINDS INCREASING THIS EVENING THAT SHOULD BREAK THESE
VERY COLD TEMPERATURES SOME. GFS FORECASTING 700MB WINDS OF 35KTS
BY 06Z TONIGHT AND UP TO 50KTS BY 12Z FRIDAY...PERSISTING INTO THE
AFTERNOON HOURS. CRAIG TO CASPER GRADIENT NOT REALLY SHOWING LOW
LEVEL (850MB) GRADIENTS SUPPORTING HIGH WINDS...BUT 700MB GRADIENT
APPROACHES 60MTRS. MOST LIKELY AREA TO SEE STRONG WINDS WILL BE
THE ARLINGTON ZONE. WENT WITH A HIGH WIND WATCH FOR ARLINGTON FOR
FRIDAY.
NEXT COLD FRONT TO MOVE INTO THE AREA SATURDAY. GFS MOST BULLISH
ON QPF WHILE NAM AND ECMWF ABOUT HALF WHAT THE GFS IS FORECASTING.
STILL THEY ARE ALL IN GOOD AGREEMENT WITH TIMING...SO CONFIDENCE
IS FAIRLY HIGH FOR A WIDESPREAD SNOW EVENT FOR SATURDAY. GOING
WITH THE LESSER QPF AMOUNTS FROM THE NAM AND ECMWF. LOOKING AT
WIDESPREAD 2-4 INCHES FOR SNOWFALL SATURDAY WITH 8-10 INCHES FOR
THE MOUNTAINS. WILL PROBABLY NEED SOME SNOW ADVISORIES ISSUED AS
THE EVENT DRAWS CLOSER. SHOULD THE GFS SOLUTION COME TRUE...MAY
NEED WARNINGS FOR THE MOUNTAINS AND I-80 CORRIDOR.
.LONG TERM...(SUNDAY THROUGH WEDNESDAY)
ISSUED AT 1254 AM MST THU NOV 13 2014
A COLD WEATHER PATTERN SHOULD PERSIST ACROSS THE CWA THROUGH MOST OF
THE EXTENDED FCST PERIOD. MEDIUM RANGE MODELS ARE IN GOOD AGREEMENT
WITH DRY NORTHWEST FLOW ALOFT OVER THE CENTRAL ROCKIES THROUGH EARLY
NEXT WEEK IN THE WAKE OF THE FRONTAL PASSAGE ON SAT. GFS AND ECMWF
BOTH SHOW A GENERAL CYCLONIC FLOW ALOFT WHICH KEEPS H7 TEMPS IN THE
NEGATIVE 12-15 DEG C RANGE THROUGH TUE. THERE MAY ALSO BE SOME FRESH
SNOW FROM THE WEEKEND STORM SYSTEM TO HELP LIMIT HEATING. DECIDED TO
TREND A BIT LOWER ON HIGHS THROUGH TUE GIVEN THE PATTERN. DOWNSLOPE
SURFACE WINDS AND MODEST WARMING ALOFT WILL YIELD A WARMING TREND
THROUGH THE REST OF THE PERIOD...WITH DAYTIME TEMPS FINALLY RISING
ABOVE THE FREEZING MARK ALONG AND EAST OF THE LARAMIE RANGE ON TUE-
THU. LOOKS TO BE A DRY WEATHER PATTERN WITH LITTLE OR NO QPF IN THE
MODELS. BEST CHANCE FOR ANY SNOW SHOWERS WOULD BE IN THE MOUNTAINS
WITH ANY WEAK ENERGY EMBEDDED WITHIN THE FLOW.
&&
.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z THURSDAY NIGHT)
ISSUED AT 1058 PM MST WED NOV 12 2014
VFR CONDITIONS WILL PREVAIL ACROSS THE AREA THROUGH THURSDAY
AFTERNOON WITH GENERALLY LIGHT WINDS. A WEATHER DISTURBANCE
MOVING IN FROM THE WEST WILL PRODUCE LIGHT SNOW SHOWERS AFTER 23Z
FOR THE WYOMING TERMINALS...WITH PERIODS OF IFR CONDITIONS
LIKELY. NEBRASKA TERMINALS SHOULD REMAIN MVFR OR BETTER THROUGH
THIS TIME.
&&
.FIRE WEATHER...
ISSUED AT 1254 AM MST THU NOV 13 2014
MINIMAL FIRE WEATHER CONCERNS WITH FAIRLY WIDESPREAD SNOWPACK IN
PLACE. WILL SEE INCREASING WINDS FOR FRIDAY WITH WESTERLY WINDS
GUSTING IN EXCESS OF 50MPH...ESPECIALLY WEST OF THE LARAMIE RANGE.
NEXT CHANCE FOR WIDESPREAD SNOW LOOKS TO BE SATURDAY WITH SEVERAL
INCHES EXPECTED.
