AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
358 PM CDT MON MAY 12 2014

.SYNOPSIS...
ISSUED AT 355 PM CDT MON MAY 12 2014

A WINTER PATTERN IS UNDERWAY FEATURING A HIGH LATITUDE
BLOCK OVER ALASKA...SPLIT FLOW ACROSS THE PACIFIC NORTHWEST AND
NORTHWEST FLOW DOWN THROUGH CANADA ORIGINATING NORTH OF 60N. THIS
PATTERN SHOULD LAST THROUGH SATURDAY WITH A RETURN TO NORMAL
TEMPERATURES SUNDAY AND ABOVE NORMAL TEMPERATURES MONDAY WITH A
CHANCE OF THUNDERSTORMS.

THE FORECAST CONCERNS TEMPERATURES AND CHANCES FOR SHOWERS AND
THUNDERSTORMS.

&&

.SHORT TERM...(THIS EVENING THROUGH TUESDAY)
ISSUED AT 355 PM CDT MON MAY 12 2014

AT 19Z WATER VAPOR IMAGERY SHOWED AN UPPER LEVEL TROUGH FROM WESTERN
MANITOBA THROUGH THE WESTERN PLAINS INTO COLORADO...WHILE A WEAK PV
ANOMALY COULD BE PICKED OUT MOVING NORTHEAST THROUGH CENTRAL
NEBRASKA. COLD AIR WAS WELL IN PLACE ACROSS THE NORTHERN AND CENTRAL
PLAINS ASSOCIATED WITH THE UPPER LEVEL TROUGH AS 850MB TEMPERATURE
READINGS WERE IN THE SINGLE DIGITS ACROSS THE DAKOTAS...MUCH OF
NEBRASKA AND THE WESTERN HALF OF KANSAS. WESTERN NEBRASKA WAS AT THE
CENTER OF THE COLD AIR...WITH THE 12Z READING AT -1C. AT THE
SURFACE...HIGH PRESSURE WAS NOTED OVER COLORADO...WITH THE SURFACE
LOW AND ASSOCIATED COLD FRONT FROM IOWA DOWN INTO EASTERN OKLAHOMA.
A TIGHT PRESSURE GRADIENT AND STRONG WINDS JUST ABOVE THE SURFACE
BROUGHT STRONG NORTHERLY WINDS THROUGH THE DAY. ALSO...THE BAND OF
MID LEVEL FRONTOGENETICAL FORCING CONTINUES TO WEAKEN THROUGH THE
MID AFTERNOON HOURS...WHICH IS BEING REFLECTED BY THE RADAR IMAGERY
AS ECHOES HAVE BEEN STEADILY DIMINISHING OVER THE LAST SEVERAL HOURS.

FOR TONIGHT...AS THE FRONTOGENETIC FORCING CONTINUES TO WEAKEN...AS
WILL THE PRECIPITATION. EXPECTING IT TO SLOWLY TREND DOWNWARDS
THROUGH THIS EVENING. TEMPERATURES ARE NOW IN THE UPPER 30S
AREA-WIDE AND WITH THE INTENSITY OF THE PRECIPITATION
DWINDLING...RAIN WILL BE THE PRECIPITATION TYPE FOR THE REMAINDER OF
THE EVENT. THESE TRENDS ARE REFLECTED IN THE CURRENT FORECAST GRID
SET.

THE PRESSURE GRADIENT WILL BE WEAKENING THIS EVENING AS WELL SO WILL
EXPECT A STEADY DECLINE IN WINDS THIS EVENING. HOWEVER THERE WILL
REMAIN ENOUGH OF A GRADIENT TO HAVE WINDS OF 7-11KTS THROUGH THE
OVERNIGHT HOURS. CLOUDS WILL BE THINNING TONIGHT AND WITH THE COLD
AIR IN PLACE ANY CLEARING WILL HELP TO DROP TEMPERATURES TO NEAR OR
BELOW FREEZING LEVELS. WITH THE WINDS...NOT EXPECTING DRASTICALLY
COLD TEMPERATURES BUT 29-35 DEGREES CERTAINLY LOOKS PLAUSIBLE AS
CURRENT TEMPERATURES ARE ONLY IN THE UPPER 30S TO LOW 40S. ALTHOUGH
IT HAS BEEN BELOW NORMAL IN TERMS OF TEMPERATURES LATELY...THE AREA
IS NOW OFFICIALLY IN THE GROWING SEASON AND WITH TEMPERATURES
EXPECTED TO DROP TO NEAR OR BELOW FREEZING WILL BE ISSUING A FREEZE
WARNING FOR AREAS ALONG AND WEST OF HIGHWAY 83 TONIGHT.

TUESDAY...UPPER LEVEL FLOW OVER THE ROCKIES AND HIGH PLAINS BECOMES
NEARLY MERIDIONAL IN THE WAKE OF THE SLOWLY DEPARTING TROUGH THAT
HAS BEEN IMPACTING THE AREA FOR THE LAST COUPLE DAYS. THIS WILL LEAD
TO WARMING TEMPERATURES HOWEVER HIGHS WILL STILL BE 10 TO 15 DEGREES
BELOW CLIMO GIVEN THAT H85 TEMPS ARE STILL ONLY 3C TO 7C OVER THE
CWA BY 00Z WEDNESDAY. KEPT MENTION OF POPS FOR THE EASTERN PANHANDLE
AND SOME OF OUR NORTHERN ZONES AS AN SHORTWAVE TROUGH ROTATES AROUND
THE LOW PRESSURE CENTER IN SOUTHWEST ONTARIO. QG FIELDS INDICATE
PREDOMINATELY SINKING AIR WHICH SHOULD HELP SUPPRESS THE SPATIAL
EXTENT OF MOST ACTIVITY...ALONG WITH LIMITED MOISTURE AND
INSTABILITY. HAVE LEFT AS SLIGHT CHANCE -RA FOR NOW.

.LONG TERM...(TUESDAY NIGHT THROUGH MONDAY)
ISSUED AT 355 PM CDT MON MAY 12 2014

TUESDAY NIGHT THROUGH THURSDAY...THE NAM AND GFS ARE SHOWING A SHOT
OF MIDLEVEL FRONTOGENESIS THURSDAY WHICH SHOULD BE SUFFICIENT TO
POOL MOISTURE AND MOISTURE UP THE LOWER LEVELS FOR LIGHT MEASURABLE
RAINFALL. ALTHOUGH THE LOCATION OF THIS RAIN VARIES IN THE MODELS
THERE IS ENOUGH AGREEMENT FOR SCATTERED SHOWERS THURSDAY. THE PTYPE
IS RAIN. THE NAM SUGGESTS THERE MIGHT BE ENOUGH COLD AIR EARLY
THURSDAY MORNING FOR WET SNOW ACROSS SHERIDAN COUNTY BUT THE MODEL
DOMINANT ICON IS RAIN AND THAT IS WHAT WILL BE FORECAST. THE GEM
NHEM MODEL DID NOT COME SO THE FORECAST USES THE NAM AND GFS. THE
09Z SREF DID NOT SHOW PCPN SO THAT SOLN WAS NOT INCLUDED. MEANWHILE
THE 12Z ECM HAS A BIG BLOB OF PCPN WEDNESDAY BUT NO FRONTOGENESIS
AND VERY LITTLE CLOUD COVER SO THAT SOLN WAS DISCARDED ALSO. THE ECM
SUGGESTS THE NEXT COLD FRONT WOULD ARRIVE WEDNESDAY VS THE SLOWER
GFS AND NAM SOLNS.

MIN TEMPERATURES WEDNESDAY MORNING SHOULD FALL BELOW FREEZING ALONG
AND WEST OF HIGHWAY 83 WITH LIGHT FROST ALONG HIGHWAY 183. THE MIN
TEMPERATURE FORECAST THURSDAY MORNING IS WARMER OWNING TO THE
INCREASE IN CLOUD COVER. A WEAK COLD FRONT WILL BE BACKING INTO THE
FCST AREA WHICH WOULD PROVIDE LESS THAN IDEA RADIATION CONDITIONS.
LIGHT NORTHWEST WINDS AND NEARLY CLEAR SKIES ARE EXPECTED WEDNESDAY
MORNING SO THIS SHOULD BE THE COLDEST MORNING.

OTHERWISE HIGH TEMPERATURES SHOULD RISE INTO THE UPPER 50S TO LOWER
60S BOTH DAYS. H700 MB TEMPERATURES HOVER AT -4C TO -10C BOTH DAYS
AND THURSDAY WOULD BE SLIGHT COOLER NORTH WITH THE FRONT BACKED.

THURSDAY NIGHT THROUGH MONDAY...THE MODELS SHOW ANOTHER LONG WAVE
TROF DROPPING INTO THE WRN U.S. SUNDAY. BOTH THE GFS AND ECM SHOW
SUFFICIENT INSTABILITY AND SHEAR FOR SEVERE WEATHER MONDAY. A CHANCE
OF THUNDERSTORMS ARE IN THE FCST FOR MONDAY.

UNTIL THEN THE FCST AREA WILL BE PLAGUED BY COLD AIR ALOFT AND
OCCASIONAL BOUTS OF MIDLEVEL FRONTOGENESIS WHICH WOULD SUPPORT
ISOLATED SHOWERS AND THUNDERSTORMS. THE GFS AND ECM SUGGEST THE BEST
CHANCE FOR RAIN WOULD BE SATURDAY WITH A DEVELOPING WARM FRONT. THIS
FRONT WOULD MOVE EAST AND AFFECT THE ERN ZONES SUNDAY.

THE TEMPERATURE FORECAST REVOLVES AROUND THE PROGRESS OF A CANADIAN
HIGH PRESSURE SYSTEM WHICH WILL SLOWLY SPREAD THROUGH THE UPPER
MIDWEST AND THE PLAINS. A GRADUAL WARMING TREND IS EXPECTED AS THIS
AIR MODIFIES AND WARMS. HIGHS IN THE UPPER 50S TO LOWER 60S
FRIDAY...60S SATURDAY...70S SUNDAY AND MONDAY.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z TUESDAY AFTERNOON)
ISSUED AT 1242 PM CDT MON MAY 12 2014

CONDITIONS WILL BE IMPROVING THROUGH THE REMAINDER OF THE
AFTERNOON AS THE SNOW AND RAIN MOVES OUT OF THE AREA LEADING TO
RISING CEILINGS AND IMPROVING VISIBILITIES ACROSS ALL OF WESTERN
AND NORTH CENTRAL NEBRASKA. THERE WILL BE SEVERAL MORE HOURS OF
SNOW...MAINLY FOR AREAS BETWEEN HIGHWAY 83 AND HIGHWAY 183. WINDS
WILL STAY STRONG THROUGH LATE AFTERNOON THEN WILL BE DIMINISHING
THROUGH THE EARLY EVENING HOURS. FOR TONIGHT AND TUESDAY...VFR
CONDITIONS ARE EXPECTED...AND WHILE WINDS WON/T COMPLETELY DROP
OFF TONIGHT...SPEEDS OF 6 TO 11KTS ARE LIKELY. THEN TUESDAY
MORNING AS THE BOUNDARY LAYER MIXES...THE WINDS WILL INCREASE WITH
SPEEDS OF 15-20KTS WITH GUSTS TO 25-30 KTS BY 18Z. WINDS WILL
CONTINUE TO BLOW FROM THE NORTHWEST THROUGH THE PERIOD.
