AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
317 PM CDT FRI OCT 5 2012

.DISCUSSION...
A FRONTOGENETICALLY FORCED SNOW BAND CONTINUES TO DRIFT SLOWLY
EAST SOUTHEAST ACROSS THE SANDHILLS THIS AFTERNOON. THIS AREA OF
SNOW SHOULD CONTINUE MOVING EAST SOUTHEAST AND WEAKEN AS THE
THERMAL FORCING RELAXES.

ANOTHER ROUND OF SNOW IS FORECAST TO DEVELOP ACROSS SWRN NEB AND
THE PANHANDLE LATE TONIGHT THROUGH EARLY SATURDAY AFTN. THIS IS
BASED ON THE CONSENSUS OF THE 12Z GFS...WRF...NAM...GEM AND 00Z
ECM. HOWEVER THE LATEST RADAR AND RAP/HRRR SOLNS ARE SUGGESTING A
MORE EASTERLY TRACK OF THE DISTURBANCE...CURRENTLY OVER MT...WHICH
COULD PRODUCE SNOW ACROSS NCNTL NEB. THE 18Z NAM IS IN EXCELLENT
AGREEMENT WITH THE GEMREG KEEPING THE BEST FORCING AND SNOW
SOUTHWEST AND ITS NOT UNUSUAL FOR THE RAP AND HRRR TO BE OFF BUT
THE RADAR TRENDS ARE OF CONCERN. A QPF BLEND OF THE MODELS ABOVE
AND A 10 TO 1 RATIO PRODUCE 1 TO 2 INCHES OF SNOW ACROSS THE FAR
WEST AND SOUTHWEST SO NO WINTER WEATHER ADVISORY WILL BE NECESSARY
ASSUMING BRIDGES AND ROAD SURFACES DONT CROSS THE FREEZING MARK
OVERNIGHT.

THE CLOUD COVER BUILDING IN AHEAD OF THIS DISTURBANCE LEAVES A
NARROW WINDOW FOR FREEZING TEMPERATURES ACROSS LINCOLN COUNTY.
OTHER AREAS WEST REMAIN OVERCAST AND AREAS NORTH AND EAST HAVE
ALREADY HAD A FREEZE.

SKIES SHOULD CLEAR OUT BY EARLY SATURDAY EVENING WITH WINDS
BECOMING LIGHT WEST OVERNIGHT. LOW PRESSURE WILL BEGIN DROPPING
SOUTH THROUGH CANADA. A BLEND OF NAM AND MET GUIDANCE WITH NAM12 BIAS
CORRECTION PRODUCED LOWS IN THE TEENS IN SOME AREAS SUNDAY
MORNING. HIGHS REBOUND INTO THE 50S SUNDAY AFTERNOON AS WEST WINDS
CONTINUE. LOWS IN THE 20S FOLLOW MONDAY MORNING WITH HIGHS AROUND
70 MONDAY AFTERNOON. WEST WINDS WILL CONTINUE THROUGH THIS PERIOD
AS LOW PRESSURE MOVES SLOWLY EAST THROUGH MANITOBA AND
SASKATCHEWAN.

TUESDAY THROUGH FRIDAY. UPPER FLOW SHOULD TRANSITION FROM
NORTHWEST FLOW ALOFT AT THE START OF THE PERIOD...TO SOUTHWEST
FLOW ALOFT TOWARD THE END OF THE WEEK AS A LARGE UPPER LEVEL LOW
PRESSURE SYSTEM PUSHES EAST OVER THE DESERT SOUTHWEST. MODELS
AGREE SOMEWHAT THAT THIS UPPER LEVEL LOW PRESSURE SYSTEM WILL
EVENTUALLY MOVE NORTHEAST TOWARD AND ACROSS OUR AREA NEXT WEEKEND.
THIS IS JUST BEYOND THE FORECAST PERIOD...AND ANY PRECIPITATION
ASSOCIATED WITH THIS SYSTEM WOULD BE BEYOND FRIDAY...SO DRY
WEATHER IS CURRENTLY BEING FORECAST THROUGH FRIDAY.
OTHERWISE...HIGH TEMPERATURES WILL STAY MOSTLY IN THE 60S...WITH
PERHAPS ONLY 50S BY FRIDAY BEHIND A COLD FRONT. THIS FRONT SHOULD
BECOME STATIONARY JUST TO OUR SOUTH LATER FRIDAY AND THEN
POTENTIALLY MOVE BACK NORTH THROUGH THE AREA DURING THE WEEKEND AS
A WARM FRONT. WILL CONTINUE TO MONITOR THE POTENTIAL SYSTEM FOR
NEXT WEEKEND.

&&

.AVIATION...
AREAS OF MVFR CEILINGS CONTINUE ACROSS PORTIONS OF SOUTHWEST AND
WESTERN NEBRASKA. THESE ARE EXPECTED TO LIFT...AND BY EARLY
EVENING MOSTLY JUST A MID LEVEL CLOUD DECK IS EXPECTED. ANOTHER
SYSTEM WILL MOVE SOUTHEAST ACROSS THE AREA AFTER 06Z
SATURDAY...WITH CEILINGS LOWERING TO MVFR AND POSSIBLE LIGHT SNOW
WEST OF A LINE FROM KIML TO KOGA TO KAIA. SFC WINDS WILL BE LIGHT
THROUGH THE PERIOD.

&&

.FIRE WEATHER...
FIRE DANGER WILL BECOME VERY HIGH SUNDAY AND MONDAY AFTERNOON.
MODEL CONSENSUS AND BIAS CORRECTED DATA SUGGESTED RH BETWEEN 15
AND 20 PERCENT WITH WINDS GUSTING TO NEAR 25 MPH BOTH DAYS.

.LBF WATCHES/WARNINGS/ADVISORIES...FREEZE WARNING FROM 10 PM THIS
EVENING TO 10 AM CDT SATURDAY FOR NEZ059.
