AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
1243 PM CST WED MAR 4 2015

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 351 AM CST WED MAR 4 2015

THE SNOW ACROSS SOUTHWESTERN NEB IS DECREASING SLOWLY AND
TEMPERATURES APPEAR TO SUPPORT SNOW GROWTH DESPITE THE WEAKENING
LIFT. THE FORECAST CALLS FOR FLURRIES THIS MORNING UNTIL SKIES
CLEAR BY MID MORNING. NORTH...AN UPPER LEVEL COLD POOL WILL BE
MOVING ACROSS NCNTL NEB THIS AFTN. THE NAM WIND AND MOISTURE
FIELDS 700MB AND BELOW SUGGEST SOME LATERAL OR TRANSVERSE
CONVERGENCE WHICH COULD PRODUCE FLURRIES THIS AFTERNOON. THE
BLENDED MODEL QPF EVEN INDICATES SOME SPOTTY VERY LIGHT QPF BUT
GIVEN THE DRY AIR BELOW 800 MB FLURRIES WOULD SEEM TO BE THE MOST
LIKELY MODE.

THE TEMPERATURE FORECAST FOLLOWS THE WARMER RAP MODEL TODAY
SUGGESTING 20S FOR HIGHS IN MOST AREAS. THE RAP WAS ACTUALLY A
BIT TOO COLD WITH THE ARCTIC BLAST MONDAY SO THE WARMER SOLN
MIGHT BE BEST TODAY.

1030 MB ARCTIC HIGH PRESSURE ACROSS ALBERTA AND SASKATCHEWAN WILL
TRACK THROUGH THE UPPER MISSOURI BASIN TODAY AND BE LOCATED OVER
WRN IOWA BY THURSDAY MORNING. WINDS SHOULD BECOME LIGHT AND
VARIABLE THIS EVENING AND THEN LIGHT SOUTHWEST AFTER MIDNIGHT.
THIS IS EXPECTED TO PRODUCE LOWS IN THE SINGLE DIGITS TO NEAR OR
SLIGHTLY BELOW ZERO IN A FEW AREAS ACROSS THE NORTH.

MORE SPRING LIKE TEMPERATURES AND DRY FOR THE LONG TERM PERIOD.
THE LONG WAVE TROUGH THAT HAS BEEN ENTRENCHED OVER THE SW CONUS
OVER THE PAST SEVERAL DAYS WILL FINALLY SLIDE EAST WITH THE
RETURN OF THE WESTERN RIDGE. THE MODELS ARE IN GOOD AGREEMENT

SEE THE FIRST DAY OF WARM AIR WITH ONLY WARMER DAYS TO FOLLOW.
850 MB TEMPS WARM TO AROUND ZERO BY 00Z FRIDAY AND CONTINUE TO
WARM INTO NEXT WEEK. THE ACTIVE WEATHER PATTERN GETS MOVED TO THE
NORTH AND EAST. WILL SEE A FEW NW FLOW CLIPPERS ACROSS THE AREA.
GENERALLY TEMPS HOLD STEADY BEHIND THE CLIPPERS AS AIR MASS
BEHIND EACH WAVE IS PACIFIC. MODEL MOS GUIDANCE IN GOOD AGREEMENT
