SHORT TERM...TODAY THROUGH WEDNESDAY...LATEST WATER VAPOR LOOP
SHOWED A HIGHLY AMPLIFIED UPPER LEVEL PATTERN WITH TROUGHS OVER
THE INTERMOUNTAIN WEST AND NORTHEAST AND RIDGES OVER THE MIDWEST
AND JUST OFFSHORE OF THE PACIFIC COAST. AS FORECAST...A CLOSED
UPPER LOW PRESSURE CENTER FORMED OVER NORTHERN ARIZONA. INFRARED
IMAGERY SHOWED MOST OF THE ENHANCED CLOUD TOPS OVER NORTHERN AND
CENTRAL WYOMING. REGIONAL RADAR AND SURFACE OBSERVATIONS INDICATED
LIGHT SNOW AT CASPER AND RIVERTON...WITH THE PRECIPITATION
SPREADING SOUTHEAST TOWARD RAWLINS AND DOUGLAS. THE STRONG COLD
FRONT WHICH BLEW THROUGH THE CWA SUNDAY EVENING WAS LOCATED ALONG
THE LEADING EDGE OF 3-5 MB/3HR SURFACE PRESSURE RISES...FROM NEAR
FARGO TO NORTH PLATTE THEN SOUTHWEST TO COLORADO SPRINGS.
SUSTAINED NORTH TO NORTHWEST WINDS OF 25 TO 35 MPH WITH GUSTS TO
50 MPH WERE COMMON BEHIND THE FRONT. TEMPERATURES HAVE FALLEN
ABOUT 20-25 DEGREES SINCE THE FRONTAL PASSAGE.
THE 00Z/06Z DETERMINISTIC AND ENSEMBLE MODEL GUIDANCE ARE IN
BETTER AGREEMENT COMPARED TO THE PREVIOUS FEW FORECAST CYCLES.
THE CLOSED UPPER LOW SHIFTS EAST FROM ARIZONA TO NEW MEXICO
TODAY...THEN MEANDERS TONIGHT AND TUESDAY FOLLOWED BY A STEADY
NORTHEASTWARD TREK INTO WESTERN KANSAS ON WEDNESDAY. SURFACE COLD
FRONT SLOWS ITS EASTWARD PROGRESS TODAY WITH THE FORMATION OF A
SURFACE LOW PRESSURE WAVE OVER THE SOUTHERN HIGH PLAINS. UPSLOPE
NORTHERLY LOW LEVEL FLOW...MOISTURE AND MID LEVEL DIVERGENCE WILL
PROVIDE THE CATALYST FOR LIGHT PRECIPITATION TODAY FOR ALL BUT
THE SOUTHEAST PORTION OF THE CWA. WET SNOW MAY ACCUMULATE TO ONE
TO THREE INCHES FOR THE MOUNTAINS THROUGH THIS AFTERNOON. STRONG
COLD AIR ADVECTION COMBINED WITH A TIGHT POST-FRONTAL PRESSURE
GRADIENT WILL GENERATE SUSTAINED NORTH TO NORTHWEST WINDS OF 25
TO 35 MPH GUSTING AS HIGH AS 50 MPH ACROSS SOUTHEAST WYOMING AND
THE WESTERN NEBRASKA PANHANDLE. A WIND ADVISORY REMAINS IN EFFECT
UNTIL 6 PM MDT FOR THE PANHANDLE. IT WILL ALSO BE AS MUCH AS
35 DEGREES MUCH COLDER THAN YESTERDAY WITH HIGHS IN THE 40S TO
MID 50S FOR THE PLAINS WITH UPPER 20S AND 30S FOR THE HIGH
COUNTRY. THE PRESSURE GRADIENT RELAXES THIS EVENING WITH WIND
SPEEDS DECREASING. PRECIPITATION WILL SHIFT SOUTH INTO COLORADO
TONIGHT AS SURFACE HIGH PRESSURE RIDGES INTO WYOMING. AS THE
UPPER LOW AND ITS SURFACE REFLECTION MOVE TOWARD WESTERN KANSAS
ON TUESDAY...MOISTURE WILL SPREAD NORTHWARD INTO EXTREME SOUTHEAST
WYOMING AND THE SOUTHERN NEBRASKA PANHANDLE. A MIX OF LIGHT RAIN
AND SNOW TUESDAY MORNING WILL CHANGE OVER TO RAIN AS TEMPERATURES
RISE INTO THE UPPER 30S AND 40S. THE RAIN AND SNOW WILL LINGER
OVER THE SOUTHEAST PORTION OF THE CWA TUESDAY NIGHT THEN SHIFT
EAST INTO CENTRAL NEBRASKA WEDNESDAY MORNING...WITH DRIER AIR
SPREADING FROM WEST TO EAST ACROSS THE CWA WEDNESDAY AFTERNOON.
LIKEWISE...HIGH TEMPERATURES WEDNESDAY WILL MODERATE TO ABOUT 10
DEGREES ABOVE SEASONAL NORMALS.
LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY...02/00Z GFS AND
02/00Z ECMWF SIMILAR ON THURSDAY SHOWING BROAD SCALE 500 MB
TROUGH OVER THE PACIFIC NORTHWEST WITH DIFFLUENT SOUTHWEST FLOW
ALOFT ACROSS WYOMING. GFS AND ECMWF SIMILAR AGAIN ON FRIDAY WITH
BROAD TROUGH ALOFT OVER THE NORTHERN ROCKIES AND PACIFIC NORTHWEST
AND FAST SOUTHWEST FLOW ALOFT ACROSS OUR COUNTIES. ON SATURDAY...
GFS AND ECMWF DIVERGE WITH ECMWF SHOWING RIDGING DEVELOPING OVER
THE PACIFIC NORTHWEST AND INCREASING 500 MB HEIGHTS OVER SOUTHERN
WYOMING TO 5700 METERS...WHILE GFS CONTINUES WITH BROAD TROUGH
OVER MONTANA AND WYOMING AND 500 MB HEIGHTS NEAR 5580 METERS OVER
SOUTHERN WYOMING... 120 METERS LOWER THAN THE ECMWF. MORE
DIVERGENCE ON SUNDAY...AS THE 02/00Z GFS SHOWS 500 MB TROUGH OVER
MONTANA AND WYOMING WITH 5640 METER 500 MB CONTOUR OVER SOUTHERN
WYOMING...WHILE IN CONTRAST...THE 02/00Z ECMWF SHOWS LOW AMPLITUDE
RIDGING OVER THE PACIFIC NORTHWEST WITH 500 MB HEIGHTS NEAR 5760
METERS OVER SOUTHERN WYOMING...AGAIN 120 METERS HIGHER THAN THE
GFS. BASED ON THE LONGWAVE PATTERN DURING MARCH...FAVOR THE WARMER
AND HIGHER HEIGHTS SHOWN ON THE ECMWF FOR THE WEEKEND. FORECAST
CONFIDENCE IS HIGH FOR THURSDAY AND FRIDAY AND LOW FOR THE WEEKEND
AS THE GFS AND ECMWF ARE STARKLY DIFFERENT SATURDAY AND SUNDAY.
WEDNESDAY NIGHT...TRANSITORY RIDGING ALOFT PREVAILS WITH RETURN
SOUTHERLY FLOW AT LOW LEVELS. DRY LOW AND MID LEVELS AND LIMITED
LIFT...THUS NO PRECIPITATION.
THURSDAY...SOUTHWEST FLOW ALOFT STRENGTHENS...INDUCING SURFACE LOW
PRESSURE TO DEVELOP AND STRENGTHEN OVER EASTERN WYOMING WITH A
THERMAL RIDGE AXIS ACROSS OUR COUNTIES...THUS MILD. STILL NOT
ENOUGH FORCING TO PRODUCE ENOUGH LIFT FOR PRECIPITATION.
FRIDAY...SERIES OF SHORTWAVE TROUGHS ROTATE NORTHEAST ACROSS
WYOMING WITH THE SURFACE LOW REDEVELOPING OVER FAR SOUTHEAST
WYOMING. FRONTAL CONVERGENCE ALONG A LOW LEVEL BOUNDARY FROM
RAWLINS TO DOUGLAS TO CHADRON ALONG WITH SOME LOW AND MID LEVEL
MOISTURE WILL PRODUCE ISOLATED TO SCATTERED AFTERNOON AND EVENING
SHOWERS AND THUNDERSTORMS.
SATURDAY...IF GFS VERIFIES...WILL SEE A COLD FRONTAL PASSAGE EARLY
IN THE DAY WITH A WINDY AND COLDER DAY AS 1000-500 MB THICKNESSES
FALL TO 5430 METERS. IF SOLUTION IS CLOSER TO THE ECMWF WITH HIGHER
HEIGHTS ALOFT...WE WILL HAVE A WARMER LESS WINDY DAY. STILL TOO
EARLY TO TELL.
SUNDAY...WILL BLEND WITH OUR NEIGHBORS AND KEEP IT DRY AS EVEN THE
MORE TROUGH GFS SHOWS LITTLE IF ANY PRECIPITATION DUE TO LIMITED
LOW AND MID LEVEL MOISTURE. BELIEVE THE WARMER AND HIGHER HEIGHT
ECMWF WILL BE CLOSER TO REALITY THAN THE GFS...THUS WOULD NOT BE
SURPRISED IF HIGH TEMPERATURES ACTUALLY ARE IN THE 60S AND 70S.
AVIATION...06Z TAF ISSUANCE...CLOUDS WILL INCREASE AND BASES
LOWER FROM WEST TO EAST OVER THE CWA THE REST OF TONIGHT AS A
PACIFIC COLD FRONT CONTINUES TO MOVE ACROSS THE REGION. THE FRONT
WILL BE THROUGH THE ENTIRE CWA BY 07Z. BEHIND THE FRONT MVFR
CEILINGS AND VISIBILITIES IN RAIN AND SNOW WILL DEVELOP THROUGH
12Z OVER SOUTHEAST WYOMING AND BASES BETWEEN 4 AND 5 THOUSAND FEET
AGL OVER THE PANHANDLE. THE LOWER CONDITIONS WILL CONTINUE THROUGH
AT LEAST MONDAY MORNING. PERIODS OF IFR CONDITIONS WILL ALSO BE
POSSIBLE DURING THAT TIME MAINLY OVER AND WEST OF THE LARAMIE
RANGE. THE SNOW LEVEL WILL BE AROUND 5500 FEET MSL LATER TONIGHT
AND MONDAY MORNING. THE SNOWY AND SIERRA MADRE RANGES WILL BE
OBSCURED THIS EVENING THROUGH EARLY AFTERNOON MONDAY. VFR
CONDITIONS NOW MAY SLOWER TO RETURN TO THE CWA AS THE STORM SYSTEM
MAY MOVE FURTHER NORTH ACROSS COLORADO AND THE CENTRAL HIGH
PLAINS.
AFTER THE FRONTAL PASSAGE...NORTH TO NORTHWEST WINDS WILL GUST
AS HIGH AS 45 KNOTS AND CONTINUE THROUGH MONDAY EVENING.
FIRE WEATHER...STRONG AND GUSTY NORTHWEST WINDS FOLLOWING THE
PASSAGE OF A COLD FRONT SUNDAY NIGHT WILL CONTINUE FOR THE EASTERN
DISTRICT...MAINLY FOR THE EASTERN PLAINS AND WESTERN NEBRASKA
THROUGH THIS AFTERNOON. IT WILL BE MUCH COLDER TODAY COMPARED TO
RECENT DAYS WITH HIGHER RELATIVE HUMIDITIES. THIS WILL MITIGATE
ANY FIRE WEATHER CONCERNS. THERE WILL ALSO BE A CHANCE FOR LIGHT
RAIN AND WET SNOW FOR MUCH OF THE DISTRICT. ONLY MINOR
ACCUMULATIONS ARE FORECAST FOR THE MOUNTAINS...WHERE ONE TO THREE
INCHES WILL BE POSSIBLE. THE PRECIPITATION WILL END LATER THIS
AFTERNOON WITH DRY CONDITIONS TONIGHT. A LOW PRESSURE SYSTEM OVER
NORTHERN NEW MEXICO WILL MOVE SLOWLY NORTHEAST INTO NORTHWEST
KANSAS TUESDAY AND TUESDAY NIGHT. MOISTURE WILL SPREAD FROM SOUTH
TO NORTH INTO FAR SOUTHEAST WYOMING AND THE SOUTHERN PANHANDLE...
WITH PERIODS OF LIGHT RAIN AND SNOW. DRIER AIR WILL FINALLY
OVERSPREAD THE DISTRICT ON WEDNESDAY AS THE LOW PRESSURE SYSTEM
MOVES FURTHER EAST. THE NEXT CHANCE FOR CRITICAL FIRE WEATHER
CONDITIONS MAY BE THURSDAY AND FRIDAY ASSOCIATED WITH THE NEXT
UPPER LEVEL TROUGH AND COLD FRONT.
