AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
349 AM MDT FRI OCT 17 2014

.SHORT TERM...(TODAY THROUGH SUNDAY NIGHT)
ISSUED AT 349 AM MDT FRI OCT 17 2014

THE VERY NICE FALL WEATHER IS EXPECTED TO CONTINUE THROUGH THE
WEEKEND. A WEAK FRONT HAS BACKED ACROSS THE PLAINS AND TEMPS ARE
CHILLY WITH MANY LOCATIONS IN THE LOW-TO-MID 30S. STRATUS IS
CURRENTLY ACROSS CENTRAL SOUTH DAKOTA AND NORTH CENTRAL NEBRASKA.
THE HRRR PUSHES THE LOW CLOUDS INTO THE FAR EASTERN ZONES BY
SUNRISE...HOWEVER BELIEVE IT MAY BE A BIT TOO AGGRESSIVE. A DROP
IN TEMPS OF 5-10 DEGREES WILL BE SEE TODAY ACROSS THE PLAINS WITH
HIGHS GENERALLY IN THE 60S AS OPPOSED TO THE 70S FROM THE PAST FEW
DAYS. HEIGHTS BEGIN TO RISE ON SAT WITH WARM ADVECTION. TEMPS WILL
BE BACK UP INTO THE UPPER 60S TO LOW 70S.  SOUTHERLY WINDS WILL BE
BREEZY DURING THE AFTN OVER THE NEBRASKA PANHANDLE AS PRESSURE
FALLS OCCUR OVER EASTERN MT DURING THE DAY. WEAK SHORTWAVE PUSHES
FROM MT INTO THE NORTHERN PLAINS ON SAT NIGHT. OTHER THAN DRAGGING
A WEAK COOL FRONT OVER THE PANHANDLE ON SUN MORNING...THIS SYSTEM
WILL HAVE VERY LITTLE EFFECT ON THE AREA. UPPER LEVEL RIDGE MOVES
OVERHEAD ON SUN FOR A CONTINUATION OF THE TRANQUIL WEATHER
CONDITIONS.

.LONG TERM...(MONDAY THROUGH THURSDAY)
ISSUED AT 349 AM MDT FRI OCT 17 2014

DRY AND MILD TO START OFF THE EXTENDED FORECAST PERIOD. UPPER
LEVEL RIDGE OVER THE ROCKIES MONDAY WILL BEGIN TO SHIFT INTO THE
PLAINS WITH A TROUGH TO PUSH INTO THE FORECAST AREA BY MID WEEK.
TEMPERATURES MONDAY WILL BE ABOVE NORMAL WITH HIGHS INTO THE 70S
ACROSS MOST OF THE LOWER ELEVATIONS AND 60S INTO THE WEST. TUESDAY
COULD BE VERY WARM FOR THE LATER PORTIONS OF OCTOBER. MAY SEE RECORD
HIGHS OVER MUCH OF THE AREA ASSUMING HIGH CLOUDS ARE NOT TOO
EXTENSIVE AHEAD OF THE UPPER LEVEL TROUGH. CHANCES FOR
PRECIPITATION WILL BE WEDNESDAY BASED ON CURRENT MODEL TIMING.
PRECIPITATION TYPE WILL BE IN THE FORM OF LIQUID...AND THAT MAY
ALSO HOLD TRUE FOR THE MOUNTAINS AS THERE WILL NOT BE MUCH IN THE
WAY OF COLD AIR FROM THIS PACIFIC SYSTEM.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z FRIDAY NIGHT)
ISSUED AT 249 AM MDT FRI OCT 17 2014

PANHANDLE. CURRENTLY WIDESPREAD IFR TO MVFR DUE TO STRATUS OVER
WESTERN SOUTH DAKOTA. THE STRATUS WILL SPILL SOUTH INTO WESTERN
NEBRASKA BY LATE TONIGHT. WINDS WILL BE LIGHT ACROSS THE AREA
THROUGH THE TAF PERIOD.
