AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
233 AM CST SUN DEC 31 2006

.SYNOPSIS...
EXTREME EASTERN PORTIONS OF THE CWA HAVE BEEN AND ARE CONTINUING
TO GET HAMMERED FROM THE DEFORMATION ZONE OVERNIGHT. 00Z MODELS
WERE TOO FAR EAST. WILL NOT BE SURPRISED IF SOME AREAS RECEIVED 6
INCHES OR MORE OF NEW SNOW WITH THIS FROM FRONTIER COUNTY
NORTHEAST THROUGH SOUTHEASTERN CUSTER...GARFIELD...WHEELER AND
EASTERN HOLT COUNTIES. WILL SEE WHAT MORNING REPORTS BRING. WATER
VAPOR PLACES THE MAIN UPPER LOW OVER THE RED RIVER AREA NORTH OF
KDFW WITH A SECONDARY UPPER LOW NEAR THE NE ND/MB BORDER. MSAS
PLACES THE SURFACE LOW AT 8Z EAST OF KFNB.

&&

.DISCUSSION...
STORM SYSTEM TRECKS TO THE NORTHEAST TODAY AND IS OVER THE GREAT
LAKES BY MIDNIGHT. THIS LEAVES THE CWA IN THE WINDY WAKE OF THE
SYSTEM. H85 WINDS AND BL WINDS INDICATE WIND ADVISORY CRITERIA BY
AFTERNOON ACROSS THE EASTERN ZONES. WILL BE BREEZY/WINDY ACROSS
THE CENTRAL AND SOUTHWEST. BLOWING SNOW WILL BE A
PROBLEM...ESPECIALLY ACROSS AREAS THAT RECEIVED FRESH SNOWFALL
OVERNIGHT. WILL GO WITH A BLOWING SNOW ADVISORY WHERE FRESH SNOW
HAS FALLEN...AND A WIND ADVISORY WITH AREAS OF BLOWING SNOW
WORDING INCLUDED FOR THE REST OF THE 26KT PLUS AREA. WILL EXPIRE
THE WINTER STORM WARNING FOR HOLT/GARFIELD/WHEELER COUNTIES AT
12Z...AND CANCEL REMAINING WINTER WEATHER HEADLINES WITH THE
ZONES. IF SNOW BAND MAKES IT INTO BOYD COUNTY WILL NOT DROP THAT
AREA FROM THE WARNING YET. MAIN CONCERN IS THAT IF SNOW DOES NOT
DECREASE AS THE NAM/GFS INDICATE...OR SLIDE FAR ENOUGH TO THE
EAST...A CONTINUATION OF THE WARNING MAY BE NEEDED FOR
HOLT/GARFIELD/WHEELER COUNTIES. IR FOR NOW IS NOT SHOWING ANY
SIGNS OF WEAKENING. IR HOWEVER DOES HAVE MAINLY CLEAR SKIES ACROSS
WESTERN ZONES AND POINTS WEST. THE NEXT INTRUSION OF CLOUDS IS
WITH THE BATCH APPROACHING WESTERN WY. GENERALLY DID NOT MAKE MANY
CHANGES TO THE REST OF THE SHORT TERM FORECAST. GUIDANCE LOOKS
MUCH TOO WARM AND HAVE MAINTAINED THE GOING COLD BIASED TEMPS.

IN THE EXTENDED...H5 LOW STILL PROGGED BY THE MODELS TO DROP
THROUGH THE SOUTHWEST CONUS MIDWEEK. ECMWF IS FURTHER
NORTH...TAKING IT TO THE SOUTHEAST CORNER OF NM WEDNESDAY
EVENING. THIS STILL LOOKS TOO FAR SOUTH OF THE AREA TO RESULT IN
ANY WEATHER ACROSS THE CWA...BUT STRONG MOISTURE ADVECTION FROM
THE GULF WILL BE THERE SO WILL HAVE TO LOOK FOR A SLOWER OR MORE
NORTHERLY TRACK. BEYOND THIS SYSTEM...WILL LOOK TO THE PACIFIC FOR
MOISTURE AS A COLD FRONT WILL RACE THROUGH TOWARD THE END OF THE
WEEK. COULD BE SOME STRONG WINDS WITH THE SYSTEM AND A QUICK SHOT
OF SNOW...ESPECIALLY ACROSS THE NORTH. THICKNESSES DROP DOWN INTO
THE 520S SO A COLD START TO NEXT WEEKEND.

&&

.AVIATION...
    THE UPPER LOW WILL BE SLOW MOVING OUT OF THE CENTRAL PLAINS...
BUT THE SUBSIDENCE BEHIND THE UPPER TROUGH SHOULD CONTINUE CLEARING
THE CLOUDS. AS A RESULT...LOW INSTRUMENT CONDITIONS WILL GRADUALLY
LIFT THIS MORNING EAST OF AINSWORTH SO THAT...BY 18Z...THEY SHOULD
NO LONGER AFFECT TWEB ROUTE 098. STILL...MARGINAL VISUAL
METEOROLOGICAL CONDITIONS WILL PROBABLY PERSIST THROUGH 20Z. FOR THE
AREA WEST OF AINSWORTH...OGALLALA...AND IMPERIAL...UNRESTRICTED VFR
IS LIKELY IN ROUTES 264...274 AND THE WESTERN HALF OF ROUTE 098.
    FOR THE TERMINAL FORECAST AT VTN AND LBF...THE MARGINAL CEILING
IS EXPECTED TO SCATTER OUT BY 10Z AS CLEARING CONTINUES IN THE
SUBSIDENCE AREA.

&&

.CLIMATE...
KLBF HAS RECEIVED 16.3 INCHES OF SNOW THIS MONTH. WITH NO
ADDITIONAL SNOWFALL EXPECTED...THIS WILL KEEP THE CITY 0.5 INCHES
BELOW THE RECORD FOR THE MONTH.

&&

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF WESTERN AND
NORTH CENTRAL NEBRASKA.

.DAY ONE...TONIGHT.

A MASSIVE WINTER STORM WILL CONTINUE TO IMPACT MUCH OF NORTH
CENTRAL AND PORTIONS OF SOUTHWEST NEBRASKA OVERNIGHT.

MUCH COOLER AIR HAS SETTLED ACROSS MOST OF WESTERN AND
NORTH CENTRAL NEBRASKA. HOWEVER...AREAS OF FREEZING DRIZZLE AND
LIGHT SNOW WILL LINGER IN AREAS GENERALLY EAST OF HIGHWAY 183
OVERNIGHT. IN ADDITION AREAS OF BLOWING AND DRIFTING SNOW WILL
CONTINUE THROUGH AT LEAST TOMORROW AFTERNOON.

THE HEAVIEST SNOWFALL IS EXPECTED MAINLY EAST OF A BROKEN BOW TO
BASSETT TO BUTTE LINE WHERE UP TO 4 INCHES OF NEW SNOW MAY FALL BY
SUNRISE ON SUNDAY. WEST OF THIS LINE...BUT EAST OF HIGHWAY
SNOWFALL AMOUNTS OVERNIGHT SHOULD BE IN THE 1 TO 3 INCH RANGE.

WINDS WILL REMAIN STRONG AT 15 TO 30 MPH AND SIGNIFICANT BLOWING
AND DRIFTING SNOW WILL CONTINUE THROUGH SUNDAY EAST OF HIGHWAY 83.
THESE WINDS WILL COMBINE WITH THE SNOW TO DROP VISIBILITIES TO 1/2 MILE

THIS IS A VERY LARGE AND SOMEWHAT UNPREDICTABLE STORM. THERE IS A
SLIGHT CHANCE THE STORM COULD ESCALATE INTO A BLIZZARD IN SOME
AREAS. THEREFORE TRAVEL IN RURAL AREAS IS GENERALLY NOT ADVISED.

14 INCHES OF SNOW ALONG AND EAST OF A HAYES CENTER THROUGH BASSETT LINE.
