AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
601 PM MDT SUN SEP 6 2015

.SHORT TERM...(THIS EVENING THROUGH TUESDAY NIGHT)
ISSUED AT 240 PM MDT SUN SEP 6 2015

THE WEATHER PATTERN WILL TRANSITION TO DRIER ZONAL FLOW OVER THE
NEXT FEW DAYS. SOUTHWEST FLOW ALOFT REMAINS IN PLACE TODAY BUT AS
THE BULK OF THE MID AND UPPER LEVEL MOISTURE HAS SHIFTED EAST OF
THE AREA...CHANCES FOR PRECIPITATION WILL BE LOW THROUGH THE
SHORT TERM PERIOD. A FEW ISOLATED SHOWERS AND THUNDERSTORMS WILL
BE POSSIBLE INTO FAR SOUTHEASTERN PORTIONS OF THE FORECAST AREA
THIS AFTERNOON AND EVENING. AN ELEVATED WARM FRONT OVER THIS AREA
MAY BE JUST ENOUGH TO KEEP CONVECTION FIRING INTO THE LATE NIGHT
HOURS OVER THE WESTERN NEBRASKA PANHANDLE. SEVERE THUNDERSTORMS
ARE NOT EXPECTED TODAY BUT A FEW STRONG WIND GUST MAY OCCUR NEAR
SHOWERS AND THUNDERSTORMS.

LATE TOMORROW AFTERNOON THERE MAY BE ANOTHER CHANCE FOR A FEW
THUNDERSTORMS MAINLY INTO THE NEBRASKA PANHANDLE. MODELS DIFFER
ON HOW MUCH LOW LEVEL MOISTURE WILL BE AVAILABLE FOR THUNDERSTORM
DEVELOPMENT. THE NAM SEEMS A BIT BULLISH WITH SURFACE DEW POINTS
AROUND 60 DEGREES AND MU CAPE VALUES TO AROUND 2500 K/KG NEAR
SIDNEY. THE GFS ON THE OTHER HAND SHOWS MUCH LESS LOW LEVEL
MOISTURE WITH DEW POINTS MAINLY IN THE 40S ACROSS THE NEBRASKA
PANHANDLE WITH MU CAPES AROUND 500 J/KG AND DECREASING BY LATE
AFTERNOON. CONFIDENCE IN EITHER SOLUTION IS LOW. IF THE NAM DOES
VERIFY THEN A FEW SEVERE THUNDERSTORMS WOULD BE POSSIBLE AS 0-6 KM
BULK SHEAR WILL BE PUSHING 50 KTS.

BY TUESDAY DRY WEST TO NORTHWEST FLOW ALOFT WILL BE IN PLACE. DRY
AIR AND DOWNSLOPE FLOW WILL PRECLUDE ANY CHANCES FOR
PRECIPITATION. IT WILL BE SLIGHTLY COOLER TUESDAY WITH HIGHS
MAINLY IN THE 70S. EXPECT BREEZY CONDITIONS ALONG AND WEST OF THE
LARAMIE RANGE WITH RELATIVELY LIGHT WINDS INTO THE PLAINS.

.LONG TERM...(WEDNESDAY THROUGH SUNDAY)
ISSUED AT 245 PM MDT SUN SEP 6 2015

ALL LONG RANGE MODELS SHOW A BENIGN WEATHER PATTERN ACROSS THE
FRONT RANGE INTO NEXT WEEKEND. MODEL SOLUTIONS FOR NEXT SUNDAY
LOOK VERY SIMILAR TO THE FORECAST SOLUTIONS FOR WEDNESDAY THIS
WEEK...SO EXPECT VERY LITTLE CHANGE TO THE OVERALL PATTERN IN THE
NEAR FUTURE. MODELS CONTINUE TO INDICATE A BROAD UPPER LEVEL RIDGE
AXIS REMAINING ACROSS THE FAR WESTERN UNITED STATES AND EASTERN
PACIFIC OCEAN...WITH A LONG WAVE TROUGH OVER EASTERN CANADA AND
EXTENDING SOUTHWARD INTO THE EASTERN UNITED STATES. THIS WILL
RESULT IN DRY NORTHWEST FLOW ALOFT ACROSS WYOMING AND WESTERN
NEBRASKA. WITH THE JET STREAM STAYING NORTH AND EAST OF THE
FORECAST AREA...THE WEATHER WILL REMAIN PRETTY QUIET AS THE STORM
TRACK WILL BE TOO FAR NORTH...AND CONVECTIVE POTENTIAL WILL BE
GREATLY DIMINISHED. A WEAK COOL FRONT IS FORECAST TO PUSH ACROSS
THE HIGH PLAINS ON FRIDAY...WHICH MAY INITIATE A FEW SHOWERS
ACROSS WESTERN NEBRASKA THROUGH FRIDAY EVENING. OTHERWISE...DRY
WEATHER IS EXPECTED INTO THE WEEKEND WITH TEMPERATURES NEAR OR
SLIGHTLY ABOVE NORMAL. HIGH TEMPERATURES WILL RANGE FROM THE 70S
TO LOW 80S...WARMEST OVER WESTERN NEBRASKA WEDNESDAY AND SATURDAY
AFTERNOON.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z MONDAY EVENING)
ISSUED AT 601 PM MDT SUN SEP 6 2015

SHOWERS WITH AN OCCASIONAL LIGHTNING STRIKE OR TWO ARE OCCURRING
ALONG I-25 FROM WHEATLAND TO KCYS...AND UP TO KBFF. SHORT TERM
GUIDANCE SUGGESTS THIS ACTIVITY WILL SHIFT TO THE NORTHEAST
THROUGH THE EARLY EVENING AND OVERNIGHT...BUT EXPECT MINIMAL
IMPACT TO THE TERMINALS FROM THIS ACTIVITY. FURTHER WEST...GUSTY
AND VERY DRY CONDITIONS WILL CONTINUE THROUGH SUNSET BEFORE
DIMINISHING OVERNIGHT. STRENGTHENING MOIST SOUTHERLY FLOW ACROSS
THE PLAINS COULD BRING LOW CLOUDS FROM KCYS TO KAIA AND POINTS
EAST...BUT CONFIDENCE IS FAIRLY LOW THAT CIGS WILL DROP BELOW
VFR. MONDAY SHOULD BE A REPEAT DRY AND BREEZY DAY FOR THE WESTERN
TERMINALS WHILE A FEW ISOLATED TSTMS ARE POSSIBLE ALONG AND EAST
OF THE SOUTHERN LARAMIE RANGE.

&&

.FIRE WEATHER...
ISSUED AT 245 PM MDT SUN SEP 6 2015

GUSTY WEST TO SOUTHWEST WINDS WILL CONTINUE THROUGH THIS AFTERNOON
NEAR AND WEST OF THE LARAMIE RANGE IN SE WYOMING. CRITICAL TO NEAR
CRITICAL FIRE CONDITIONS WILL CONTINUE ACROSS THE AFOREMENTIONED AREA
THROUGH THE AFTERNOON HOURS BUT WINDS WILL QUICKLY SUBSIDE THIS
EVENING WHILE RELATIVE HUMIDITY VALUES WILL RECOVER. SIMILAR
CONDITIONS WILL DEVELOP MONDAY IN THE SAME AREAS WITH HUMIDITY
VALUES DROPPING TO BETWEEN 10 AND 20 PERCENT ALONG WITH WESTERLY
WINDS GUSTING 25 TO 35 MPH.
