AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
326 AM CST SUN DEC 14 2008

.DISCUSSION...

FORECAST CHALLENGE IN THE NEAR TERM FOCUSES ON THE ARCTIC AIR AND
IMPACTS. THE ARCTIC FRONT IS THROUGH THE FORECAST AREA WHERE NORTHWEST
WINDS ARE INCREASING USHERING THE COLDER AIR SOUTH WHILE THE 08Z
3 HOUR PRESSURE RISES WERE ON THE ORDER OF 9 MBS ACROSS THE SOUTHWEST.
AREAS OF LIGHT SNOW CONTINUE ACROSS PORTIONS OF THE SANDHILLS
WITH THE RADAR MOSAIC SHOWING RETURNS MOVING FROM THE SOUTHWEST
TO NORTHEAST. GOOD FRONTOGENETICAL FORCING IS EXPECTED TO SHIFT
SOUTHEAST BEYOND 18Z AT WHICH TIME SNOWFALL SHOULD DIMINISH INTO
THE AFTERNOON FROM NORTHWEST TO SOUTHEAST.

TODAY THE ARCTIC HIGH WILL RIDGE FURTHER SOUTHEAST AS THE LOW
PRESSURE SYSTEM LIFTS NORTHEAST TOWARD THE GREAT LAKES.
UNIDIRECTIONAL WINDS FROM THE SFC TO H85 WILL RESULT IN STRONG
WINDS THROUGHOUT THAT WILL CREATE SOME BLOWING SNOW TO THE NORTH
WHERE SNOW ACCUMULATION UP TO 5 INCHES MAY OCCUR IN AREAS NORTH
OF HIGHWAY 20 EAST TO VALENTINE THEN IN AREAS NORTH OF THE
NIOBRARA RIVER EAST TO LYNCH AND MONOWI. A BLIZZARD WARNING
REMAINS IN EFFECT FOR THE AREA WITH VALENTINE ASOS RECORDING 1/4SM
+SN AT 0839Z. STORM TOTAL SNOW ACCUMULATIONS WILL BE HINDERED BY
THE WINDS AS BLOWING SNOW WILL CREATE SOME DRIFTS THAT MAY BE
OBSERVED ACROSS THE FAR NORTH. AS THE MAIN FORCING SHIFTS
SOUTHEAST TODAY SNOWFALL AMOUNTS WILL TAPER OFF TO AN INCH OR LESS
FOR THE FAR SOUTHWEST. A BUFFER ZONE REMAINS WITH A WINTER WEATHER
ADVISORY IN EFFECT UNTIL 6 PM THIS EVENING AND WIND ADVISORY IN
EFFECT FOR MUCH OF THE SOUTH CENTRAL AND SOUTHWEST. TEMPERATURES
ARE ALREADY DROPPING ACROSS THE MAP FOR EARLY MORNING DAYTIME
HIGHS WITH TEMPERATURES EITHER STEADY OR FALLING INTO THE
AFTERNOON.

TONIGHT THE COLDER AIR WILL CONTINUE TO SPILL ONTO THE PLAINS WITH
ANY CLEARING TO LEAD TO RAPID DROPS IN TEMPERATURES. OVERNIGHT
SUBZERO TEMPERATURES AND STRONG GUSTY NORTHWEST WINDS WILL CREATE
CRITICAL WIND CHILL VALUES FOR MOST AREAS NORTHEAST OF A LINE FROM
ANTIOCH IN SHERIDAN COUNTY TO OCONTO IN CUSTER COUNTY WITH A WIND
CHILL ADVISORY POSTED FROM 6 PM TONIGHT TO NOON MONDAY. THE COMBINATION
OF COLD AIR AND GUSTY WINDS WILL DRIVE WIND CHILL VALUES DOWN WITH
READINGS FROM 20 BELOW TO 30 BELOW ZERO THAT CAN BE LIFE
THREATENING IF CAUGHT OUTDOORS FOR A PROLONG PERIOD. PRECAUTIONS
SHOULD BE TAKEN TODAY TO MOVE LIVESTOCK THAT MAY BE IMPACTED BY
THE EXTREMELY COLD AIR.

LITTLE CHANGE IN THE PATTERN IS EXPECTED THROUGH TUESDAY WHEN
THERE WILL BE ANOTHER CHANCE FOR SNOW AS A SYSTEM LIFTS OUT OF THE
SOUTHWEST. AS SURFACE WINDS TURN TO THE SOUTHEAST TEMPERATURES
WILL CLIMB ABOVE SUBZERO TEMPERATURES ACROSS THE NORTH BUT NO
SIGNIFICANT WARMING EXPECTED THROUGH THE EXTENDED PERIOD.

&&

.AVIATION...

MVFR CONDITIONS ARE EXPECTED TO CONTINUE OVER ALL OF WESTERN AND
NORTH CENTRAL NEBRASKA TODAY WITH INTERMITTENT IFR CONDITIONS CIGS
AT BOTH KVTN AND KLBF AND VISIBILITIES AT KVTN. STRONG NORTHWEST
WINDS 25 TO 35 MPH WITH GUSTS TO NEAR 50 MPH WILL INTENSIFY WITH
MIXING ACROSS NORTH CENTRAL NEBRASKA THIS MORNING.
