AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
524 AM MDT THU SEP 11 2014

.SHORT TERM...(TODAY THROUGH SATURDAY)
ISSUED AT 306 AM MDT THU SEP 11 2014

AN ACTIVE START TO THE DAY AS THE MUCH ANTICIPATED AUTUMN STORM
SYSTEM HAS FINALLY ARRIVED. WATER VAPOR SATELLITE IMAGERY CLEARLY
SHOWS THE SHARP MIDLVL SHORTWAVE DIVING ACROSS THE INTERMOUNTAIN
WEST AS OF 09Z THIS AM. THE ASSOCIATED SFC COLD FRONT HAS ALREADY
MOVED THROUGH MOST OF THE CWA...BUT THE 00Z H7 ANALYSIS SHOWED THE
COLDER AIR LAGGING CONSIDERABLY WITH THE 0C LINE ALONG THE MONTANA
AND WYOMING STATE LINE. DEEPER COLD AIR HAS MANAGED TO PROGRESS A
LITTLE FURTHER SOUTH OVER THE PAST FEW HOURS WITH SNOW OBSERVED AT
RAPID CITY AND GILLETTE. REGIONAL RADAR MOSAIC SHOWS THE SOUTHERN
EDGE OF THIS PCPN BAND ALONG A DGW TO CDR LINE. SO FAR TEMPS IN
THE 35 TO 40 DEGREE RANGE HAVE KEPT THIS IN THE FORM OF RAIN. WE
SUSPECT LUSK MAY CHANGE OVER SOON AS FCST SOUNDINGS APPEAR TO BE
SUFFICIENTLY COLD BY 12Z. FOG IS THE OTHER NEAR-TERM ISSUE. MOIST
LLVL UPSLOPE HAS BECOME ESTABLISHED ALONG AND EAST OF THE LARAMIE
RANGE. THIS WILL SUPPORT AREAS OF FOG AND WIDESPREAD DRIZZLE THRU
MOST OF THE MORNING. VSBY MAY IMPROVE SLIGHTLY BY AFTN...BUT VERY
LOW STRATUS SHOULD PERSIST ALL DAY IN THIS REGIME.

IT WILL BE A CHILLY ONE TODAY AS SUBSTANTIAL SFC HEATING WILL BE
NEXT TO IMPOSSIBLE WITH PERSISTENT LOW STRATUS AND COLD ADVECTION
ALOFT. THE I-80 CORRIDOR HAS THE BEST CHANCE OF REACHING 50F THIS
AFTN AS THE MODELS HAVE THE BEST H7 CAA HOLDING OFF UNTIL AFTER
21Z THU...OTHERWISE 40S OR EVEN UPPER 30S WILL BE COMMON. PCPN IS
DEFINITELY TOUGH TO GET A HANDLE ON. GFS/ECMWF/NAM ALL ARE IN GOOD
AGREEMENT WITH PCPN INCREASING FROM NORTH TO SOUTH FROM THIS AFTN
THROUGH EARLY FRI AM. THIS WILL MOST LIKELY CHANGE TO SNOW OVER
MOST OF THE CWA BY 00Z-03Z FRI AS H7 TEMPS FALL BELOW -4C PER THE
06Z NAM. GOOD MIDLVL FRONTOGENESIS AND DIVERGENCE IN THE RRQ OF A
110 KT H25 JET STREAK COMBINED WITH MOIST LLVL UPSLOPE FLOW GIVES
CREDENCE TO HIGHER SNOWFALL RATES FOR A SHORT TIME. HOWEVER THIS
IS A VERY PROGRESSIVE SYSTEM WITH THE BEST DYNAMICS CLEARING MOST
OF THE AREA BY 03Z FRI. THINK THIS WILL LIMIT AMOUNTS TO AN INCH
OR TWO ON GRASSY SURFACES...BUT COULD SEE MORE ACROSS THE NORTHERN
TIER OF COUNTIES IF PERMANENT CHANGEOVER OCCURS EARLY ENOUGH. WILL
NEED TO MONITOR FOR A POSSIBLE WINTER WEATHER ADVISORY IF IT LOOKS
LIKE RATES WILL BE HIGH ENOUGH TO GET ACCUMULATION ON ROADS. STILL
CANNOT RULE OUT SOME FREEZING DRIZZLE EARLY TOMORROW MORNING WITH
THE LACK OF SATURATION COLDER THAN -10C ON NAM/GFS BUFKIT SOUNDING
DATA...BUT SFC TEMPERATURES WILL BE MARGINAL.

ISSUED A FREEZE WARNING FOR AREAS WEST OF THE LARAMIE RANGE FROM
MIDNIGHT TONIGHT THROUGH 15Z FRI. THIS IS WHERE CONFIDENCE IS THE
HIGHEST IN A KILLING FREEZE AND WHERE WINTRY PCPN IS VIRTUALLY A
NON FACTOR. THE EASTERN PLAINS ARE ON THE MARGINAL SIDE AS STRATUS
IS EXPECTED TO KEEP OVERNIGHT LOWS FROM FALLING RAPIDLY. PLUS IF
SNOW BANDING DOES OCCUR...WE WANTED TO AVOID ANY CONFUSION WITH
MULTIPLE PRODUCTS SHOULD WINTER ADVISORIES BECOME NECESSARY. FOR
THAT REASON...WILL CONTINUE TO HIGHLIGHT NEAR FREEZING TEMPS IN AN
SPS AND MENTION AREAS OF FROST IN THE NDFD GRIDS. THINGS MODERATE
QUICKLY ON FRI WITH SHORTWAVE RIDGING AND LLVL WAA KICKING IN BY
MID AFTN. LOW CLOUDS WILL PROBABLY HANG AROUND FOR A GOOD CHUNK OF
THE DAY...BUT AM CONFIDENT WE WILL SEE SUNSHINE LATER IN THE DAY
AS FCST SOUNDINGS SUGGEST GRADUAL LLVL DRYING AFTER 18Z. STILL NOT
PARTICULARLY WARM THOUGH WITH SUB-FREEZING TEMPS ALOFT. WARMER AND
DRY FOR SAT BENEATH QUASI-ZONAL FLOW ALOFT AND H7 TEMPS REBOUNDING
INTO THE MID SINGLE DIGITS C.

.LONG TERM...(SUNDAY THROUGH WEDNESDAY)
ISSUED AT 306 AM MDT THU SEP 11 2014

SATURDAY NIGHT...NOT AS COLD AS FRIDAY NIGHT WITH AIRMASS
MODIFICATION AND A LITTLE BETTER LOW LEVEL MIXING.

SUNDAY/MONDAY...SLOW WARMING TREND AS THE AIRMASS CONTINUES TO
MODERATE WITH NO PRECIPITATION DUE TO DRY LOW AND MID LEVELS.

TUESDAY/WEDNESDAY...DRY AND MILD DAYS WITH THE RIDGING ALOFT SLOWLY
ADVANCING OVER OUR COUNTIES...AND DRY LOW AND MID LEVELS MAKING FOR
PRECIPITATION FREE DAYS.

LIKELY ON THURSDAY NIGHT THROUGH FRIDAY MORNING ALONG WITH AN
