AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
1044 PM MDT SUN OCT 13 2013

.UPDATE...
ISSUED AT 1043 PM MDT SUN OCT 13 2013

STORMS HAVE WEAKENED SOME AT MID EVENING OVER THE PANHANDLE.
HOWEVER...MUCH OF THE EASTERN PANHANDLE IS STILL BEING AFFECTED
BY THUNDERSTORMS. THE STORMS SHOULD CONTINUE TO WORK THEIR WAY
EAST AND BE EAST OF THE CWA BY 06Z. MEANWHILE...SHOWERS
CONTINUE TO SLOWLY INCREASE OVER AREAS WEST OF THE LARAMIE RANGE.
THAT AREA SHOULD SPREAD EAST THROUGH EARLY MONDAY MORNING AND
OVER THE REST OF THE CWA AS THE STORM SYSTEM MOVES EAST AND OVER
THE CWA. SIGNIFICANT LIFT IS CURRENTLY OCCURRING OVER CARBON
COUNTY WITH THUNDERSTORMS INCREASING. SNOTEL OBSERVATIONS WOULD
INDICATE THAT THE SNOW LEVEL WEAS DOWN TO ABOUT 8500 FEET AS OF
04Z. THE SNOW LEVEL SHOULD LOWER THE REST OF TONUGHT AND MONDAY
MORNING TO ABOUT 6500 FEET AS THE COLD AIR SPREADS EAST WITH THE
STORM SYSTEM. MADE SOME MAINLY MINOR ADJUSTMENTS TO THE FIRST
PERIOD IN A RECENT UPDATE.

UPDATE ISSUED AT 723 PM MDT SUN OCT 13 2013

SOME THUNDERSTORMS HAVE FORMED OVER SOUTHEAST WYOMING SINCE 0030Z.
THE STRONGEST WAS JUST MOVING NORTHEAST OF KCYS AT 0115Z. THAT STORM
PRODUCE A PERIOD OF HEAVY RAIN...LIGHTNING AND EVEN SMALL HAIL.
TRIED TO INCLUDE THE STORMS IN A RECRNT YPDATE.

UPDATE ISSUED AT 627 PM MDT SUN OCT 13 2013

SOME SHOWERS CONTINUE OVER THE WEST PART OF THE CWA AT 00Z. THE
TEMPERATURES HAVE BEEN SLOWLY COOLING OVER THE HIGHER ELEVATIONS
AND SNOW SHOWERS MAY BE POSSIBLE AT ELEVATIONS ABOVE 10000 FEET
CURRENTLY. PREVIOUS FORECAST LOOKS ON TRACK FOR NOW AND ONLY MINOR
CHANGES MADE IN A RECENT UPDATE.

&&

.SHORT TERM...(TONIGHT THROUGH TUESDAY)
ISSUED AT 249 PM MDT SUN OCT 13 2013

THE RETURN TO COLDER AND MORE UNSETTLED CONDITIONS WILL BE MARKED
EARLY IN THE UPCOMING WEEK AS A TROUGH OF LOW PRESSURE SWINGS
THROUGH THE AREA. SATELLITE PIX EARLY THIS AFTERNOON DEPICT THIS
LARGE AMPLITUDE TROUGH BOTTOMING OVR THE GREAT BASIN...WITH A
DEVELOPING BAROCLINIC LEAF AHEAD OF IT OVR CENTRAL WYOMING. SFC
ANALYSIS CLEARLY SHOWED LEE-CYCLOGENESIS UNDERWAY WITH GENERAL
PRESSURE FALLS OVR THE UPSTREAM CENTRAL ROCKIES. REGIONAL RADARS
HAVE BEEN SLOW TO RETURN ANYTHING THUS FAR...BUT EXPECT THAT TO
CHANGE THROUGH THE REMAINDER OF THE AFTERNOON AS MID-LEVEL TEMPS
COOL WILL THE APPROACH OF THE TROUGH. LIFTED INDICES FALL TO
AROUND -2 OR -3C ALONG WITH 300-600 J/KG OF SBCAPE. THE RESULT
WILL BE FOR CONVECTION TO EXPAND TONIGHT. SNOW LEVELS WILL BEGIN
AT AROUND 10 KFT EARLY THIS EVENING AND WILL SLOWLY FALL FROM
NORTHWEST TO SOUTHEAST LATE TONIGHT/MONDAY MORNING AS THE COLDER
AIR IS PULLED SOUTH. SNOW WILL MAINLY BE OVER THE SNOWY/SIERRA
MADRES THIS EVENING...BUT WILL DESCEND TO THE WESTERN
FLOORS/VALLEYS BETWEEN MIDNIGHT AND SUNRISE. AREAS EAST OF THE
LARAMIE RANGE WILL REMAIN RAIN THROUGH THE OVERNIGHT HOURS. BY
DAYBREAK...EXPECT ONLY LIGHT ACCUMULATIONS ACROSS LOWER ELEVATIONS
OF CARBON/ALBANY COUNTIES. BEST SYNOPTIC LIFT PER QG FIELDS IS
BETWEEN THE 06Z-15Z TIME FRAME...SO HAVE CONTINUED THE TREND OF
INCREASING PRECIPITATION CHANCES THEN. SNOW LEVELS WILL CONTINUE
TO FALL THROUGH THE DAY ON MONDAY. THUS EXPECT AN EVENTUAL MIX
WITH AND/OR CHANGE OVER TO SNOW FOR EASTERN PLAINS LOCATIONS ABOVE
ABOUT 5 KFT BY MONDAY AFTERNOON. ELEVATIONS BELOW 5 KFT IS
EXPECTED TO REMAIN RAIN THROUGH THIS ENTIRE EVENT. BY LATE MONDAY
AFTERNOON...PRECIPITATION CHANCES WILL WANE AS LARGE SCALE
SUBSIDENCE ENSUES BEHIND THE DEPARTING TROUGH. AS FOR SNOWFALL
TOTALS...EXPECT 5 TO 10 INCHES OF SNOW TO FALL OVER THE
SNOWY/SIERRA MADRES WITH 4 TO 8 INCHES ACROSS MAINLY THE NORTHERN
SLOPES OF THE NORTHERN LARAMIE RANGE. ALTHOUGH A MARGINAL EVENT ON
THE ACCUMULATION SIDE...HAVE OPTED TO ADD THE NRN LARAMIE RANGE
ZONE TO THE WINTER WEATHER ADVISORY WITH THE FAVORABLE NORTHERLY
LOW LEVEL FLOW. LOWER ELEVATIONS WEST OF THE LARAMIE RANGE WILL
LIKELY SEE GENERALLY UP TO A COUPLE OF INCHES. MUCH OF THE AREAS
OUT ON THE EASTERN PLAINS WILL NOT SEE ANY ACCUMULATION...ALTHOUGH
UP TO AN INCH WILL BE POSSIBLE FROM CHEYENNE TO DOUGLAS.

THE OTHER CONCERN WITH THE EVENT WILL BE THE STRONG NORTHWEST WINDS
THAT WILL DEVELOP ON MONDAY. PROGS SO FAR CONTINUE TO PAINT LESS
VALUES COMPARED TO THE EVENT LATE LAST WEEK. SO WOULD EXPECT MOST
AREAS OUT ON THE EASTERN PLAINS TO SEE 45 TO 55 MPH WIND GUSTS EARLY
MONDAY AFTERNOON. AGAIN...WILL NEED TO WATCH THIS CLOSELY AS ANY
INCREASE IN THE GUIDANCE OUTPUT WOULD PUSH US INTO HIGH WIND
CRITERIA.

WINDS WILL DECREASE SOME MONDAY NIGHT...BUT WILL REMAIN BREEZY
ESPECIALLY OVER THE WESTERN NEBRASKA PANHANDLE. SHOWERS WILL LINGER
AS WELL...MAINLY OVER THE MOUNTAINS AS WELL AS EAST CENTRAL WYOMING.
LOW LEVEL THERMAL TROUGH WILL BE CENTERED OVER THE AREA ON TUESDAY...
WHICH WILL BE THE COLDEST DAY OF THE UPCOMING WEEK. H7 TEMPERATURES
OF AROUND -10C WILL ONLY YIELD HIGHS IN THE 30S WEST OF THE LARAMIE
RANGE AND 40S EAST.

.LONG TERM...(TUESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 239 PM MDT SUN OCT 13 2013

SOME MODEL SPREADS STILL PRESENT LATER THIS WEEK...WITH THE GFS
TRENDING SLIGHTLY IN FAVOR OF THE ECMWF. THE ELONGATED UPPER TROUGH
OVER THE CENTRAL ROCKIES/PLAINS SHIFTS SOUTHEAST TUESDAY NIGHT AND
WEDNESDAY...REPLACED BY A TRANSITORY SHORTWAVE RIDGE. THIS RIDGE
WILL BRING A BRIEF RESPITE FROM THE COOL AND INCLEMENT PATTERN
WITH DRY AND MILDER CONDITIONS WEDNESDAY THROUGH THURSDAY MORNING.
THE MODELS MAINTAIN A HIGH AMPLITUDE EASTERN PACIFIC RIDGE LATER
IN THE WEEK...WITH AN AMPLIFYING UPPER TROUGH DIGGING SOUTH ALONG
THE FRONT RANGE THURSDAY THROUGH FRIDAY. A COLD FRONT WILL SURGE
SOUTHEAST FROM THE CANADIAN PRAIRIES THROUGH THE REGION BY THURSDAY
MORNING. UPSLOPE NORTH TO NORTHEAST LOW LEVEL FLOW WITH DYNAMIC
LIFT FROM UPPER TROUGH WILL BRING WIDESPREAD PRECIPITATION TO THE
CWA...BEGINNING ACROSS NORTHERN COUNTIES THURSDAY MORNING AND
SPREADING INTO THE SOUTHERN COUNTIES DURING THE AFTERNOON. IT WILL
BE BREEZY WITH GUSTY NORTHWEST WINDS...ESPECIALLY FOR THE PLAINS.
COOLER TEMPERATURES THURSDAY NIGHT AND FRIDAY...WITH 700MB
TEMPERATURES LOWERING TO -9 TO -11C. TROUGH AND UPPER LIFT EXITS
SOUTHEAST OF THE CWA FRIDAY NIGHT WITH DRIER NORTHWEST FLOW ALOFT
DOMINATING FOR THE WEEKEND. 700MB TEMPERATURES REBOUND TO -1 TO 2C
WITH HIGHS INTO THE 50S SUNDAY.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z MONDAY EVENING)
ISSUED AT 1043 PM MDT SUN OCT 13 2013

CLOUD BASES WILL LOWER THE REST OF TONIGHT AND MONDAY MORNING
OVER THE CWA. MVFR CEILINGS AND VISIBILITIES IN RAIN AND SNOW
WERE ALREADY PRESENT IN MANY LOCATIONS. THOSE CONDITIONS WILL
BECOME WIDESPREAD EARLY MONDAY MORNING WITH PERIODS OF IFR

KNOTS OVER AREAS EAST OF THE LARAMIE RANGE ON MONDAY AND MONDAY
NIGHT.

.FIRE WEATHER...
ISSUED AT 249 PM MDT SUN OCT 13 2013

NO FIRE WEATHER CONCERNS THIS WEEK AS AN AREA OF LOW PRESSURE BRINGS
A RETURN TO COLDER AND UNSETTLED CONDITIONS EARLY IN THE WEEK. AREAS
WEST OF THE LARAMIE RANGE WILL LIKELY SEE ACCUMULATIONS FROM THIS
SYSTEM WITH 5 TO 10 INCHES EXPECTED TO FALL OVER THE SNOWY/SIERRA
MADRE RANGES. NORTHWEST WIND GUSTS OF 45 TO 55 MPH CAN BE EXPECTED
FOR AREAS EAST OF THE LARAMIE RANGE ON MONDAY AS WELL. TUESDAY WILL
