AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
329 AM MST FRI MAR 8 2013
.SHORT TERM...TODAY THROUGH SATURDAY NIGHT...
THE WINTER STORM IS STILL ON TRACK TO AFFECT THE CWA TONIGHT THROUGH
EARLY SATURDAY NIGHT. THE MID AND UPPER LEVEL CLOSED LOW WAS NOTED
ON SATELLITE IMAGERY ALONG THE SOUTHERN CALIFORNIA COAST EARLY THIS
MORNING. THE CIRCULATION APPEARED TO BE HEADING MORE EAST SINCE THE
LATE EVENING HOURS. WILL LEAN TOWARD THE MORE CONSISTENT ECMWF WITH
THE STORM...BUT ALL 00Z MODELS ARE TRENDING SLIGHTLY FASTER. THE
UPPER LOW WILL MOVE TO NEAR KLAS BY 00Z AND THEN NEAR THE 4 CORNERS
AREA AT 12Z SATURDAY. THE ASSOCIATED SURFACE LOW WILL CONTINUE TO
DEEPEN OVER SOUTHEAST COLORADO WITH THE SYSTEM NEARLY VERTICALLY
STACKED ON SATURDAY. THE STORM THEN HEADS EAST ON SATURDAY AND BY
06Z SUNDAY WILL BE OVER KANSAS.
PRECIPITATION HAS BEEN DEVELOPING AHEAD OF THE STORM EARLY THIS
MORNING OVER UTAH UNDER THE AREA WITH COLD SATELLITE CLOUD TOPS.
SYNOPTIC LIFT AND MOISTURE INCREASE FROM WEST TO EAST OVER THE
REGION TODAY THROUGH SATURDAY MORNING. STRONGLY DIFFLUENT 300 MB
WIND FLOW WILL BE OVER THE CWA TONIGHT AND SATURDAY MORNING ALONG
WITH MID LEVEL CONVERGENCE AND WARM AIR ADVECTION. THE FORECAST
RAOBS SUGGEST FAIRLY STEEP LAPSE RATES ABOVE THE BOUNDARY LAYER
AND WILL ENHANCE SNOWFALL RATES MAINLY LATE TONIGHT AND SATURDAY
MORNING. PRECIPITATION TYPE WILL START OUT AS RAIN OVER THE LOWER
ELEVATIONS AND THEN SWITCH OVER TO SNOW AS THE NIGHT GOES ON. THERE
COULD EVEN BE SOME FREEZING DRIZZLE OVER THE PANHANDLE FOR A TIME
LATE THIS EVENING THROUGH EARLY SATURDAY MORNING. A FEW LIGHTNING
STRIKES ARE ALSO POSSIBLE THIS AFTERNOON AND EVENING OVER THE
SOUTH PART OF THE CWA.
THE SNOW WILL BE HEAVY AT TIMES MAINLY IN THE AREA SOUTH OF A KLAR
TO KAIA LINE BETWEEN 06Z AND 21Z SATURDAY. INITIAL RAIN AS WELL
AS WARMER GROUND MAY REDUCE SOME OF THE ACCUMULATIONS. IN ANY
EVENT...SIGNIFICANT ACCUMULATIONS OF SNOW WILL BE POSSIBLE OVER MUCH
OF THE CWA TONIGHT AND SATURDAY...ESPECIALLY THE SOUTHEAST HALF.
WILL HAVE AMOUNTS OF 6 TO 10 INCHES OVER THE SOUTHEAST HALF OF THE
CWA AS WELL AS THE SNOWY AND SIERRA MADRE RANGES. LESSER AMOUNTS
ARE EXPECTED OVER THE NORTHWEST PART OF THE CWA. ALONG WITH THE
SNOW WILL BE STRONG NORTHERLY WINDS...MAINLY OVER THE EAST PART OF
THE CWA. GUSTS WILL BE AS HIGH AS 45 MPH WITH 40 TO 50 KNOTS FROM
THE MODELS AT 700 MB. THE TIGHTER SURFACE PRESSURE GRADIENT SEEMS
TO BE SATURDAY AFTERNOON AND EARLY SATURDAY NIGHT...A BIT OFF OF THE
TIMING OF THE HEAVIER SNOWFALL.
THE COMBINATION OF THE SNOW AND WINDS WILL PRODUCE WIDESPREAD
BLOWING AND DRIFTING SNOW...AND POOR TRAVEL CONDITIONS. HAVE
UPGRADED THE WATCHES TO WARNINGS OVER THE SOUTHEAST HALF OF THE CWA
AND ADVISORIES OVER MUCH OF THE NORTHWEST PART OF THE CWA TONIGHT
THROUGH EARLY SATURDAY NIGHT.
CONDITIONS IMPROVE FROM WEST TO EAST LATE SATURDAY AFTERNOON AND
SATURDAY NIGHT AS THE STORM SYSTEM MOVES AWAY.
.LONG TERM...SUNDAY THROUGH THURSDAY...
WARMER WEATHER TO RETURN ON SUNDAY AS UPPER RIDGE SHIFTS ACROSS THE
REGION THOUGH WILL UNDERCUT GUIDANCE DUE TO EXPECTED SNOWCOVER WHICH
SHOULD HOLD TEMPERATURES DOWN SOMEWHAT. MILD AND DRY WEATHER SHOULD
THEN SETTLE IN OVER THE CWA FOR MUCH OF NEXT WEEK AS A GENERALLY
NWLY TO WNWLY UPPER FLOW SETS UP AHEAD OF A BROAD AND RATHER FLAT
UPPER RIDGE OVER THE WESTERN PART OF THE COUNTRY. WEAK IMPULSES
WILL MOVE THROUGH THIS RIDGE AND ACROSS THE REGION BUT MAIN EFFECT
WILL BE TO BRING SOME PERIODS OF INCREASED WINDS MAINLY AROUND THE
MTNS THOUGH NO HIGH WIND THREATS ARE EVIDENT AT THIS TIME.
&&
.AVIATION...12Z TAF ISSUANCE...
AREAS OF IFR CEILINGS AND VISIBILITIES IN FOG WILL STILL BE POSSIBLE
BY 12Z OVER THE PANHANDLE. THOSE CEILINGS WITH IMPROVED VISIBILITIES
COULD PERSIST FOR MUCH OF THE CWA THE REST OF TODAY.
OTHERWISE...VFR CONDITIONS WILL BE OVER THE CWA TODAY...WITH THE
HIGHER MOUNTAIN PEAKS OBSCURED. A STORM SYSTEM WILL INCREASE
MOISTURE OVER THE REGION AND CLOUD BASES WILL LOWER TONIGHT. MVFR
CEILINGS AND VISIBILITIES IN RAIN AND SNOW WILL BE COMMON BY LATE
EVENING...WITH IFR CEILINGS AND VISIBILITIES IN LIGHT SNOW
WIDESPREAD AFTER 09Z. THE IFR CONDITIONS WILL PERSIST THROUGH 21Z
SATURDAY. AFTER THAT TIME...IMPROVEMENT WILL BE NOTED OVER THE WEST
AND NORTH PARTS OF THE CWA AS THE STORM SYSTEM STARTS TO MOVE AWAY.
VFR CONDITIONS WILL RETURN TO THE CWA AFTER 06Z SUNDAY AND PERSIST
THROUGH NEXT WEEK. THE MOUNTAINS WILL BE OBSCURED TONIGHT THROUGH
SATURDAY NIGHT.
NORTHERLY SURFACE WINDS WILL GUST AS HIGH AS 45 KNOTS OVER THE EAST
PART OF THE CWA SATURDAY AND EARLY SATURDAY NIGHT. THOSE STRONG
WINDS WILL HELP TO REDUCE VISIBILITIES DUE TO BLOWING SNOW.
&&
.FIRE WEATHER...
TEMPERATURES WILL BE COOLER TODAY...WINDS LIGHTER AND RELATIVE
HUMIDITY VALUES HIGHER. THEN A STORM SYSTEM WILL MOVE ACROSS THE
CENTRAL ROCKIES AND THEN OVER THE PLAINS TONIGHT THROUGH SATURDAY
NIGHT. THE STORM WILL PRODUCE WIDESPREAD ACCUMULATING SNOW AS
WELL AS STRONG NORTHERLY WINDS. AFTER NEAR TO JUST BELOW NORMAL
TEMPERATURES FOR SUNDAY...WARMER AND DRIER AIR WILL RETURN TO THE
DISTRICT FOR NEXT WEEK AS HIGH PRESSURE IN THE UPPER ATMOSPHERE
MOVES OVER THE ROCKIES.
