NATIONAL WEATHER SERVICE CHEYENNE WY
1048 PM MDT MON APR 13 2015

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY NIGHT)
ISSUED AT 208 PM MDT MON APR 13 2015

CLEAR AND QUIET WEATHER WILL PERSIST OVER THE CWA OVERNIGHT INTO
TUESDAY MORNING. CHANGES ENSUE DURING THE DAY TUESDAY AS A POTENT
UPPER TROF MOVES OVER THE PACIFIC NW THEN DIGS SOUTHEASTWARD
TUESDAY NIGHT...CLOSING OFF AN UPPER LOW OVER UTAH BY WEDS MORNING.
WARMEST DAY OF THE WEEK WILL BE TOMORROW WITH MAXS REACHING INTO
THE 70S ACROSS MUCH OF THE PLAINS. WINDS WILL BECOME GUSTY OVER
MUCH OF THE CWA BY LATE MORNING AS FASTER MID-LEVEL FLOW MIXES

BELOW HIGH WIND LEVELS. MAY NEED A WIND ADVY FOR THE PANHANDLE
TUESDAY AFTERNOON BUT WILL LET LATER SHIFTS REVIEW THAT.

COLD FRONT WILL SWEEP EAST ACROSS THE CWA LATER TUESDAY NIGHT INTO
EARLY WEDS AS THE UPPER LOW DIGS TOWARDS THE 4 CORNERS AREA WITH
SHOWERS AND MAYBE A FEW STORMS SPREADING INTO FAR WESTERN PARTS
OF THE CWA BY EVENING. COULD BE A FEW HIGH BASED SHOWERS OVER SE
WY BUT DRY AIR SHOULD HINDER MUCH IN THE WAY OF DEVELOPMENT. MUCH
COOLER WEDS WITH RAIN AND SNOW SPREADING ACROSS MUCH OF THE CWA BY
LATE IN THE DAY. ACCUMULATING SNOWS SHOULD STAY CONFINED TO THE
MTNS BUT SOME POSSIBLE OVER THE ADJACENT HIGH PLAINS WEDS NIGHT AS

MODEL DIFFERENCES ARE APPARENT WITH THE 12Z FORECAST CYCLE. THE
MODELS AGREE THAT THE LARGE SCALE SPLIT FLOW PATTERN WILL CONTINUE...
BUT DIFFER ON THE TIMING AND AMPLITUDE OF THE LARGE SCALE FEATURES.
THE LARGE CLOSED UPPER LOW IN THE VICINITY OF THE FOUR CORNERS
REGION IS PROGGED TO SLOWLY WEAKEN AS IT DRIFTS EAST ACROSS THE
SOUTHERN ROCKIES AND PLAINS THROUGH SATURDAY. THE MODELS DEPICT
MOST OF THE PRECIPITATION WITH THIS SYSTEM MAINLY SOUTH OF A
DOUGLAS TO ALLIANCE LINE THURSDAY...GRADUALLY SHIFTING SOUTH INTO
COLORADO THURSDAY NIGHT AND FRIDAY. IT WILL BE COOLER THAN NORMAL
WITH HIGHS THURSDAY IN THE 40S TO NEAR 50. SNOW LEVELS WILL DROP
FROM 7000 FT TO 5500 FT THURSDAY NIGHT. THE SNOWY...SIERRA MADRE
AND SOUTH LARAMIE RANGES MAY RECEIVE A FEW INCHES OF SNOW.

DRIER NORTHERLY FLOW RETURNS WITH THE PASSAGE OF SHORTWAVE UPPER
RIDGE FRIDAY NIGHT AND SATURDAY. THE ECMWF/ENSEMBLE DOES PULL SOME
MOISTURE FROM THE SOUTHERN STREAM UPPER LOW NORTHWARD...PRODUCING
ISOLATED SHOWERS SATURDAY AFTERNOON AND EVENING ALONG AND SOUTH OF
A LARAMIE TO ALLIANCE LINE. THEN THE NEXT NORTHERN STREAM TROUGH
AND ACCOMPANYING COLD FRONT WILL PUSH SOUTHEAST ACROSS THE CWA
SATURDAY NIGHT AND SUNDAY WITH CHANCES FOR SHOWERS ONCE AGAIN.
UNSETTLED WEATHER WILL LIKELY PERSIST THROUGH AT LEAST MONDAY
MORNING WITH SHORTWAVE ENERGY IN NORTHWEST FLOW ALOFT.
TEMPERATURES WILL MODERATE TO NEAR OR SLIGHTLY ABOVE SEASONAL
NORMALS FRIDAY AND SATURDAY...THEN COOL BELOW NORMAL FOR SUNDAY
