AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
154 PM CST THU FEB 22 2007

.SYNOPSIS...
IT APPEARS THE ARCTIC AIR HAS DRIFTED A LITTLE FARTHER SOUTH AND EAST
THROUGH THE MISSOURI BASIN AND INTO NCNTL NEB THAN ANTICIPATED
EARLIER. DEVELOPING SFC LOW PRESSURE OVER THE NRN INTERMOUNTAIN
REGION WILL MAINTAIN A SFC BOUNDARY ACROSS THE MISSOURI BASIN AND
PERHAPS EVEN FARTHER SOUTH. THE 12Z MAV GUIDANCE HAS RESPONDED BY
FCSTING MUCH COOLER TEMPS (3-5F) ACROSS NCNTL ZONES FOR SATURDAY.
THIS INCREASES THE PROBABILITY OF FREEZING RAIN FROM BROKEN BOW
NORTH AND EAST. THIS IS A STORM TYPICAL PATTERN.

SOUTHEAST RETURN FLOW WILL CONTINUE TONIGHT AND INCREASE THROUGHOUT
THE DAY FRIDAY.

A WINTER STORM WATCH WILL BE ISSUED FOR PARTS OF WESTERN AND NCNTL
NEB.

&&

.DISCUSSION...
TONIGHT-FRIDAY NIGHT...SELY WINDS WILL STRENGTHEN. THE NAM...GFS
AND GUIDANCE ALL INDICATE FOG...STRATUS FORMATION TONIGHT AND THE
NAM SHOWS FREEZING DRIZZLE COULD DEVELOP THROUGH 15Z. THIS IS VERY
CONSISTENT WITH DEEP PLAINS CYCLOGENESIS EVENTS.

THUNDERSTORMS ARE POSSIBLE FRIDAY EVENING AS THE THE SFC LOW DROPS
THROUGH THE WRN HIGH PLAINS AND DEEPENS DRAGGING THE 850 MB COLD
FRONT SOUTH. THE COMBINATION OF STRONG WARM AIR ADVECTION AHEAD OF
THE LOW...DEEPENING MOISTURE AND SYNOPTIC SCALE LIFT APPEARS TO BE
FAVORABLE FOR STORMS TO DEVELOP. OFTEN TIMES STORMS WILL FIRE RIGHT
ALONG THE 850MB COLD FRONT WHICH WILL ALSO BE THE RAIN SNOW IN THIS
CASE PRODUCING THUNDER SNOW.

SATURDAY-SUNDAY...MODELS CONTINUE TO CONVERGE ON A SFC LOW DEEPENING
TO NEAR 988MB ACROSS NRN KS AND TRACKING EAST AT 15 MPH ON SATURDAY
THROUGH NORTHERN KS. THE GENERAL CONSENSUS OF THE UKMET...NAM...GFS
AND ECMWF ARE WINTER STORM CONDITIONS WILL DEVELOP LATE FRIDAY NIGHT
AND CONTINUE SATURDAY AND SATURDAY NIGHT ACROSS PARTS OF WESTERN AND
NCNTL NEB. THE UKMET IS THE SLOWER AND SHOWS WINTER STORM CONDITIONS
STILL UNDERWAY ACROSS THE NERN ZONES SUNDAY MORNING. THE NAM AND THE
GFS ARE FASTER EXITING THE STORM BY 12Z SUNDAY. THE WATCH WILL BEGIN
AROUND 3 AM SATURDAY MORNING AND CONTINUE ACROSS PARTS OF THE FCST
AREA UNTIL 9 AM SUNDAY MORNING. THIS IS THE MIDDLE OF ALL THE MODELS
WHICH VARY THE STORM EXITING BETWEEN 12Z SUNDAY AND 18Z SUNDAY.

QPF VALUES RANGE FROM 1/2 TO 1 INCH IN THE UKMET TO 1 1/2 INCHES IN
THE GFS WITH THE NAM SHOWING LOCALLY AMOUNTS RANGING FROM NEAR ZERO
TO 1 3/4 INCHES. THE OFFICIAL FCST USES THE CONSERVATIVE UKMET QPF
WHICH PRODUCES 4 TO 8 INCHES OF SNOW. THIS IS A SLIGHT INCREASE OVER
THE PREVIOUS FCST AND IS WETTER THAN THE HPC GUIDANCE. SNOWFALL
AMOUNTS ASSUME A RAIN/FREEZING RAIN/SNOW LINE FORMS AND SOME OF THE
QPF FALLS AS RAIN BEFORE CHANGEOVER TO SNOW. WE ALSO HAVE HIGH LIQUID
CONTENT COURTESY OF THE EL NINO 3.4 REGION OF THE PACIFIC AND THE
GULF OF MEXICO. H7 TEMPS WARMER THAN -10C SO THE STORM HAS LESS THAN
PRIME THERMODYNAMICS FOR SNOW GROWTH. IT IS QUITE POSSIBLE LATER FCST
WILL INCREASE THE FCST SNOWFALL AMOUNTS CONSIDERABLY BUT THIS IS THE
FIRST FCST THAT HAS SHOWN ANY MODEL CONSENSUS IN FCST QPF.

WINDS HAVE BEEN FAIRLY CONSISTENT IN THE NAM ALTHOUGH THE MAV
GUIDANCE IS ABOUT 3-4KTS STRONGER THAN THE MET SATURDAY AFTN. WITH
THE 15 MPH STORM MOTION SPEED...THE WEAKER NAM WINDS ARE FAVORED
BUT THESE SPEEDS MAY NEED TO BE INCREASED IF THE MAV GUIDANCE
CONTINUES TO TREND HIGHER. AND IF THE MODELS CONTINUE TO TREND COLDER
PARTS OF THE FCST AREA MAY NEED TO BE PLACED UNDER A BLIZZARD WATCH.
SIMILARLY...COOLER MAV TEMPS HAVE BEEN BLENDED INTO THE FCST FOR
SATURDAY WHICH PLACES HIGHS IN THE LOWER 30S WITH A FEW MID 30S
SOUTHWEST.

MONDAY-TUESDAY...RECOVERY DAYS WITH WEAK WARM AIR ADVECTION.

WEDNESDAY-THURSDAY...MODEL SOLNS OF THE GFS AND ECMWF APPEAR TO
SUGGEST ANOTHER VERY STRONG STORM SYSTEM WILL TRACK THROUGH THE
CNTL PLAINS. 20 POP FOR RAIN OR SNOW HAVE BEEN INTRODUCED DURING THE
TIME FRAME. LATER FCSTS WILL RAISE THIS PROBABILITY IF MODELS
CONTINUE TO ADVERTISE THIS FEATURE.

&&

.AVIATION...
VFR CONDITIONS THE REST OF THE AFTERNOON AND INTO TONIGHT. THEN
AREAS OF MVFR STRATUS AND FOG WILL DEVELOP OVER SOUTHERN AREAS AND
LIFT NORTHWARD DURING THE EARLY MORNING HOURS TOMORROW. AS
TEMPERATURES FALL DURING THE LATE NIGHT HOURS...PATCHY DRIZZLE OR
FREEZING DRIZZLE MAY ALSO DEVELOP. MVFR STRATUS WILL BE SLOW TO LIFT
TO VFR DURING THE LATE MORNING AND EARLY AFTERNOON HOURS TOMORROW.

&&

.LBF WATCHES/WARNINGS/ADVISORIES...WINTER STORM WATCH LATE FRIDAY
NIGHT THROUGH SUNDAY MORNING ZONES 024-025-035>037-056-069>071.

1010 PM CST THU FEB 22 2007 /910 PM MST THU FEB 22 2007/

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

.DAY ONE...TONIGHT.

ABUNDANT LOW LEVEL MOISTURE WILL FLOW INTO WESTERN AND NORTH
CENTRAL NEBRASKA OVERNIGHT. WIDESPREAD FOG IS POSSIBLE AFTER
MIDNIGHT. VISIBILITIES MAY BE REDUCED TO UNDER A MILE AT TIMES.
PATCHY FREEZING DRIZZLE IS ALSO POSSIBLE LATE TONIGHT...ALTHOUGH
ICE ACCUMULATION IS EXPECTED TO BE MINIMAL...EVEN A LITTLE ICE CAN
CREATE SLICK CONDITIONS.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.

FOG WILL BURN OFF BY LATE MORNING ACROSS THE OUTLOOK AREA. ON
FRIDAY AFTERNOON...A POTENT UPPER LEVEL LOW PRESSURE SYSTEM WILL
LIFT NORTHEAST FROM THE DESERT SOUTHWEST INTO THE SOUTHERN
ROCKIES. AS THIS SYSTEM PUSHES EAST OF THE SOUTHERN ROCKIES FRIDAY
EVENING...IT WILL COMBINE WITH ABUNDANT GULF MOISTURE...LEADING TO
SCATTERED THUNDERSTORMS. AT THIS TIME...THE BEST CHANCES FOR
WIDESPREAD THUNDERSTORMS IS EAST OF A LINE FROM SPRINGVIEW...TO
ARNOLD...TO EUSTIS. WEST OF THIS LINE...ISOLATED TO SCATTERED
THUNDERSTORMS ARE EXPECTED. NO SEVERE WEATHER IS ANTICIPATED AT
THIS TIME.

A COLD FRONT WILL BEGIN TO WORK THROUGH WESTERN AND NORTH CENTRAL
NEBRASKA OVERNIGHT FRIDAY NIGHT. RAIN SHOWERS...WILL GRADUALLY MIX
WITH FREEZING RAIN BEFORE CHANGING OVER TO SNOW BY EARLY SATURDAY
MORNING. WIDESPREAD ACCUMULATING SNOWS ARE LIKELY ACROSS MOST OF
WESTERN AND NORTH CENTRAL NEBRASKA. THE GREATEST THREAT FOR SNOW
TOTALS GREATER THAN 6 INCHES IS EAST OF A LINE FROM VALENTINE...TO
CHAPPELL. IN ADDITION TO SNOW...STRONG NORTHERLY WINDS...GUSTING
TO 45 MPH WILL PRODUCE CONSIDERABLE BLOWING AND DRIFTING OF
SNOW...AND AT TIMES NEAR BLIZZARD LIKE CONDITIONS.

PERSONS PLANNING TRAVEL ACROSS WESTERN AND NORTH CENTRAL NEBRASKA
THIS WEEKEND SHOULD CONTINUE TO CLOSELY MONITOR THE LATEST
FORECASTS AND STATEMENTS.

WEATHER CONDITIONS ARE EXPECTED TO IMPROVE ON SUNDAY AS THE WINTER
STORM MOVES EAST OF THE AREA. HOWEVER...ANOTHER POTENTIALLY MAJOR
WINTER STORM IS EXPECTED TO MOVE ACROSS THE PLAINS ON WEDNESDAY
AND THURSDAY. ADDITIONAL SIGNIFICANT SNOWFALL IS POSSIBLE. AS IS
THE CASE WITH ANY WINTER STORM...THE TRACK AND STRENGTH OF THE
STORM IS KEY TO WHERE AND WHEN THE HEAVIEST SNOW WILL FALL. AT
THIS TIME THE TRACK IS STILL UNCERTAIN...AND PERSONS SHOULD
CONTINUE TO MONITOR THE LATEST FORECAST AND STATEMENTS.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED THROUGH TONIGHT.
