.SHORT TERM...(TONIGHT THROUGH MONDAY NIGHT)
ISSUED AT 248 PM MDT SAT SEP 13 2014

SHOT OF COLD AND SNOW BUT A MEMORY NOW AS PLEASANT LATE SUMMER
WEATHER WILL HOLD ACROSS THE CWA THROUGH EARLY NEXT WEEK.
TEMPERATURES WILL BE MILD SUNDAY AND MONDAY AS A WEAK SFC BOUNDARY
HOLDS GENERALLY ALONG THE HIGHER TERRAIN. A MINOR REINFORCING SHOT
OF COOLER AIR WILL PUSH DOWN THE PLAINS LATE SUNDAY BUT HAVE
LITTLE EFFECT ON MAXS FOR MONDAY. MODELS HINT AS A BIT OF MOISTURE
REACHING UP TO AROUND THE COLORADO BORDER AREA SUNDAY AFTERNOON
WITH A WEAK IMPULSE PASSING ACROSS THUS HAVE OPTED TO ADD SOME LOW
SHOWER POPS MAINLY AROUND THE SRN MTNS SUNDAY AFTERNOON. MAY NEED
TO NUDGE THOSE TO THE EAST LATER SUNDAY BUT FOR NOW WILL KEEP POPS
VERY LOW IN THAT AREA. DRY AGAIN MONDAY. SOME LOW CLOUDS AND
PATCHY FOG COULD DEVELOP OVER PARTS OF THE SRN PANHANDLE AND MAYBE
EVEN EXTREME SE WY LATE SUNDAY NIGHT IF ENOUGH MOISTURE COMBINES
WITH UPSLOPE FLOW.


.LONG TERM...(SUNDAY NIGHT THROUGH SATURDAY)
ISSUED AT 248 PM MDT SAT SEP 13 2014

A QUIT PERIOD OF WEATHER THROUGH THE LONG TERM FORECAST AS AN
UPPER LEVEL RIDGE WILL BE IN CONTROL OF WEATHER CONDITIONS. THE
RIDGE WILL SLOWLY BUILD NORTH WHILE SPREADING INTO THE ROCKIES
THROUGH MID WEEK. TEMPERATURES WILL BE BACK TO NORMAL AND EVEN
ABOVE NORMAL FOR MANY PLACES WEDNESDAY AND THURSDAY. HIGH
TEMPERATURES SHOULD RANGE FROM THE MID TO UPPER 70S FOR AREAS WEST
OF THE LARAMIE RANGE...WHILE 80S WILL BE COMMON IN THE EAST. COULD
EVEN SEE A FEW 90 DEGREE READINGS INTO THE NEBRASKA PANHANDLE.
CHANCES FOR PRECIPITATION WILL BE NEARLY NONEXISTENT THROUGH
THURSDAY WITH DRY AIR AND BROAD SCALE SUBSIDENCE IN PLACE. NOT
UNTIL FRIDAY IS THERE A CHANCE FOR PRECIPITATION ACROSS MUCH OF
THE AREA. GFS AND ECMWF BOTH SHOWING A TROUGH PUSHING INTO THE
WESTERN CONUS WITH SHORTWAVE ENERGY BREAKING DOWN THE BACKSIDE OF
THE SYNOPTIC SCALE RIDGE FRIDAY. GIVEN THE AMPLIFIED WEATHER
PATTERN THIS UPCOMING WEEK...WOULD NOT BE SURPRISED TO SEE ANOTHER
DRY WARM FRIDAY WITH THE TROUGH HOLDING OFF UNTIL FRIDAY NIGHT OR
SATURDAY.
