AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
302 PM CST SAT DEC 20 2008

.SHORT TERM...TONIGHT THROUGH 12Z MONDAY.

FIRST ISSUE TO DEAL WITH WILL BE WIND CHILLS. ORD HAS BEEN MEETING
WIND CHILL ADVISORY ALL DAY AND BEEN HANGING AROUND 2 DEGREES.
VIRTUALLY ALL LOCATIONS IN THE CENTRAL/NORTH CWA ARE IN THE SINGLE
DIGITS GRAND ISLAND IS EVEN GETTING CLOSE TO WIND CHILL ADVISORY
CRITERIA. THERE IS A VERY GOOD CHANCE THAT TEMPERATURES WILL REALLY
TANK TONIGHT. ESPECIALLY CONSIDERING THE FACT WE COULD HAVE A GREAT
DEAL OF THE NIGHT WITH CLEAR SKY AND SNOW ON THE GROUND EVERYWHERE.
WIND DOES LOOK LIKE IT WILL SLACK OFF A BIT TOWARD LATE AFTERNOON
AND EARLY EVENING...BUT COLD AIR ADVECTION...ESPECIALLY IN THE
NORTHEAST CWA WILL HELP BOOST WIND SPEEDS ONCE AGAIN AS THE NIGHT
WEARS ON. POSSIBLE INCREASE IN SKY COVER/FLURRIES TOWARD THE
SOUTHWEST CWA. PERTURBATION SHOWING UP IN THE NORTHERN ROCKIES IS
BEING DETECTED BY SOME MODELS AND COULD SQUEEZE SOME FLURRY ACTIVITY
IN OUR SOUTHWEST AS IT RIDES DOWN INTO OUR NECK OF THE WOOD WITHIN
NORTHWEST FLOW. WENT WITH A WIND CHILL WARNING FOR ROUGHLY THE SAME AREA
AS WHERE THE WIND CHILL WATCH WAS...AND ADDED AN ADVISORY AREA FOR
EVERYWHERE ELSE EXCEPT FOR THE FAR SOUTHWEST WHERE WIND WILL BE
LIGHTEST AND TEMPERATURES GENERALLY A BIT WARMER.

AS WIND PICKS BACK UP ON SUNDAY...THE COLDEST WIND CHILLS WILL OCCUR
EARLY SUNDAY MORNING FOR MANY LOCATIONS. ESPECIALLY IN OUR
NORTHEAST...IT LOOKS LIKE WE COULD CONTINUE TO MEET WIND CHILL
ADVISORY CRITERIA IN THE WIND CHILL WARNING AREA...SO LET THE WIND
CHILL WARNING GO THROUGH 00Z SO THAT THE DAY SHIFT WILL PROBABLY
DOWNGRADE DURING SUNDAY AFTERNOON...AND WIND CHILL ADVISORY GO TIL
18Z WHERE CONDITIONS SHOULD IMPROVE BY AFTERNOON. COULD HAVE SOME
SPOTS  TECHNICALLY STAY IN WIND CHILL ADVISORY LEVEL INTO THE EARLY
EVENING BUT WILL LET THE DAY SHIFT TOMORROW EVALUATE THIS.

SUNDAY NIGHT COULD BE QUITE COLD AS WELL. PLENTY OF COLD AIR WILL
STILL BE AROUND AND WIND WILL BE LIGHTER. SOME LOCATIONS MIGHT WIND
UP COLDER THIS MORNING...BUT WIND CHILLS SHOULD NOT BE A BIG ISSUE
AS THE CENTER OF THE SURFACE HIGH WILL BE NEARBY OR JUST TO THE
EAST...WITH PERHAPS SOME LIGHT RETURN FLOW BEGINNING TO OCCUR.

.LONG TERM...12Z MONDAY THROUGH SUNDAY. MAIN FORECAST CONCERNS WILL
BE CHANCE FOR SNOW MONDAY NIGHT THROUGH TUESDAY NIGHT AND
TEMPERATURES.

A SURFACE HIGH PRESSURE SYSTEM MOVES TO THE EAST ON MONDAY AND WINDS
TURN TO THE SOUTH AND INCREASE. A WEAK SHORT WAVE MOVES THROUGH THE
AREA AND THE CLOUDS WILL INCREASE DURING THE AFTERNOON. A STRONGER
WAVE MOVES INTO THE AREA MONDAY NIGHT. EXPECT THAT THERE COULD BE
SOME LIGHT SNOW IN THE NORTH AHEAD OF A COLD FRONT. THE COLD FRONT
MOVES THROUGH THE FORECAST AREA SOMETIME ON TUESDAY. MODELS HAVE
SOME SLIGHT DIFFERENCES IN THE TIMING BUT GENERALLY ON TUESDAY.
LIGHT SNOW WILL CONTINUE ON TUESDAY AS A REINFORCING WAVE SLIDES
INTO THE AREA. THERE IS A CHANCE FOR SNOW TUESDAY NIGHT IN THE
SOUTHEAST UNTIL THE MAIN UPPER TROUGH MOVES THROUGH THE AREA. LATE
TUESDAY NIGHT A HIGH PRESSURE SYSTEM STARTS TO PUSH INTO THE AREA
AND BRINGS AN END TO THE SNOW AND DECREASES CLOUDS.

ON WEDNESDAY THE HIGH PRESSURE SYSTEM MOVE TO THE EAST AND ONCE AGAIN
WINDS TURN TO THE SOUTH AND INCREASE. THIS TIME THE SOUTH WINDS
ACTUALLY BRING SOME WARM ADVECTION TO THE AREA. TEMPERATURES DO NOT
WARM A LOT ON WEDNESDAY BUT BY WEDNESDAY NIGHT SLIGHTLY WARMER AIR
IS IN PLACE AND ON THURSDAY THE TEMPERATURES ARE WARMER. THE WARMER
AIR LINGERS INTO FRIDAY. A WEAK COLD FRONT MOVES THROUGH THE AREA ON
FRIDAY BUT THIS FRONT IS DRY ACROSS THE FORECAST AREA. THE COLDER
AIR BEHIND THE COLD FRONT STAYS MOSTLY TO THE NORTH OF THE FORECAST
AREA AND TEMPERATURES WILL ONLY COOL A LITTLE FOR SATURDAY.
