AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
338 AM CDT WED OCT 22 2008

.SYNOPTIC...
UPPER TROF HAS BEEN DIGGING DOWN THE ROCKIES TONIGHT WITH 120KT+ JET
DROPPING DOWN THE WESTERN SIDE OF THE TROF. WATER VAPOR SHOWING PV
LOBE ASSOC WITH JET...ON THE NOSE OF WHICH CONVECTION HAS BEEN
SUSTAINED WELL INTO THE EARLY MORNING HOURS. SFC ANALYSIS HAS SHOWN
THE LOW HAD PROGRESSED FROM SE COLORADO INTO CENTRAL KS THE PAST 8
HOURS. GOES DPI SHOWING STRONG MOISTURE FEED FROM TX GULF COAST INTO
PLAINS AND THIS IS HELPING TO FEED THE CONVECTION. 1040 HIGH IS
MOVING INTO NORTHERN ROCKIES AND THIS TIGHTENING GRADIENT IS
BEGINNING TO INFLUENCE SFC WIND SPEEDS.

.DISCUSSION...
VERY COMPLICATED FORECAST IN STORE TODAY WITH CHALLENGES TO
TIMING...TYPE AND AMOUNT OF PRECIPITATION OVER THE NEXT 36 HOURS OR
SO...THEN MIX IN SOME WIND JUST FOR FUN. WILL HAVE PLETHORA OF
HEADLINES TO COVER THIS COMPLEX SCENARIO WITH CONFIDENCE LOW IN
CHANGE OVER HAD TO KEEP WIND HIGHLIGHTS FOR THE DAYTIME WITH WINTER
HEADLINES TO KICK IN TONIGHT. ONE BIG CONCERN ATTM IS THE VERY
SHALLOW WARM AIR LAYER AT SFC IN BUFKIT SOUNDINGS THAT COULD EASILY
BE OVERCOME BY DYNAMIC COOLING THROUGH THE DAY. ALL INDICATION ARE
THAT WET BULB TEMPS FROM SFC TO LOWER PBL WILL REMAIN WARM ENOUGH
THAT PCPN WILL HAVE A CHANCE OF REMAINING LIQUID AND THIS IS BACKED
UP BY TOP DOWN METHOD...BUT THICKNESS VALUES IN H85-H7 LEVEL EASILY
SUPPORTS A CHANGE OVER TO SNOW. TEMPERATURES UPSTREAM ATTM ARE NOT
FALLING...IN FACT SOME PLACES GAINED A FEW DEGREES IN THE PAST HOUR
AS WINDS ARE INCREASING. LASTLY WARM GROUND TEMPS FROM
RAINFALL...TIME OF YEAR AND RECENT WARM WEATHER MAY HAMPER ACCUMS
UNTIL HEAVIER BAND OF PCPN CAN GET ESTABLISHED. BELIEVE THIS AREA
WILL BE OVER PORTIONS OF SW AND CENTRAL NEB WHERE WE HAVE DECIDED TO
INITIATE WINTER STORM WARNING BEGINNING THIS EVENING. PIECE OF
WESTERN UPPER JET WILL RE-FORM ON FRONT SIDE OF UPPER LOW DURING THE
EVENING HOURS AND THIS CYCLONICALLY CURVED JET LOOKS TO HELP INDUCE
A MID LEVEL FRONTO BAND OVER SANDHILLS WITH THE WARM SIDE
CIRCULATION EXTENDING NEAR A HAYES CENTER TO ARNOLD LINE THEN MOVING
SOUTHEAST THROUGH THE NIGHT. X-SECTIONS INDICATE FAVORABLE
INSTABILITY OVER FRONTO BAND AND STRONG AGEO CIRCULATION LIFTING
MOISTURE THROUGH DENDRITIC LAYER SO WOULD EXPECT A DECENT BAND OF
MODERATE TO HEAVY SNOW IN THIS AREA OF TROWAL. THIS SNOWFALL SHOULD
BE WET WITH TEMPS NEAR FREEZING AND DO NOT EXPECT MUCH BLOWING OR
DRIFING WITH THIS WET SNOWFALL. WINDS WILL BE QUITE STRONG IN
COMBINATION WITH THIS SNOWFALL AND WAS A BIG FACTOR IN PUSHING
WARNING WESTWARD...WHERE ACCUMS COULD BE SIGNIFICANTLY LESS BUT
WINDS HIGHER CREATING HAZARDOUS DRIVING CONDITIONS. AS UPPER LOW
WOBBLES EARLY THURSDAY TROWAL LOOKS TO BE PUSHED NORTHWARD ALONG
WITH ASCENT AND INSTABILITY SHOW FRONTO BAND MAY LIFT BACK NORTH
INTO SANDHILLS FOR ADDITIONAL ACCUM SO WARNING IS TAKEN UP TO
HIGHWAY 2...AND ADVISORY NORTH OF THIS. AS FOR SNOW TOTALS THINK 4-8
WOULD BE THE GENERAL COVERAGE...HOWEVER IF FRONTO BAND SETS UP
STRONGER COULD SEE SOME TOTALS APPROACHING A FOOT. SYSTEM SHOULD
BEGIN TO WIND DOWN THURSDAY EVENING AS QG LIFT BEGINS TO WEAKEN WITH
DRY WEATHER THROUGH REMAINDER OF FCST. MADE SOME TWEAKS TO
TEMPS...ESPECIALLY WITH EXPECTED SNOW COVER...AND PROBABLY NOT LOW
ENOUGH IN THESE AREAS IF WE GET SIG ACCUMS. LOOKS TO BE A DECENT
WARMUP IN SNOW FREE AREAS WITH RIDGE GETTING SQEEZED INTO AREA AHEAD
OF NEXT STRONG SYSTEM AND BACK DOOR FRONT SAT NIGHT WITH COOL DOWN
SUNDAY INTO EARLY NEXT WEEK PROABLE.

&&

.AVIATION...
AN INTENSE STORM SYSTEM WILL IMPACT THE KLBF
TERMINAL...AND TO A LESSER DEGREE AT THE KVTN TERMINAL...OVER THE
NEXT 24 HOURS. NORTHERLY WINDS WILL INCREASE TO 30 TO 40 KTS TODAY
AND PERSIST THROUGH 12Z THURSDAY. RAIN SHOWERS ARE LIKELY TODAY AT
BOTH TERMINALS WITH MVFR CEILINGS EXPECTED. CONDITIONS WILL
DETERIORATE THIS EVENING AS WINTRY WEATHER IMPACTS WESTERN AND
NORTH CENTRAL NEBRASKA.

MODERATE TO HEAVY SNOW IS LIKELY TONIGHT AT THE KLBF TERMINAL.
FREQUENT VISIBILITIES UNDER A MILE AND IFR CEILINGS ARE LIKELY. IN
ADDITION TO SNOW...STRONG NORTHERLY WINDS WILL PRODUCE BLOWING
SNOW...WHICH WILL REDUCE VISIBILITIES FURTHER.

FOR THE KVTN TERMINAL...LIGHT SNOW IS POSSIBLE TONIGHT...WITH
PERIODIC VISIBILITIES BETWEEN 1 AND 3 MILES AND MVFR CEILINGS.
