AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
330 AM CDT THU APR 23 2009

.DISCUSSION...
UPPER RIDGE MOVING OVHD AND SHOULD PUSH INTO GREAT LAKES REGION
TODAY AS TROF DIGS ALONG WEST COAST...PHASED WITH HIGH LATTITUDE
VORTEX NEAR H.BAY. THIS WILL FORCE STRONG LLVL THERMAL RIDGE INTO
HIGH PLAINS INCLUDING SANDHILLS AND NORTH CENTRAL NEBRASKA. THIS
WILL SERVE TO WARM TEMPS WELL ABOVE NORMAL INTO THE MID AND UPPER
80S WITH 90 PROBABLY NOT OUT OF REACH IN VTN AREA...AND ADD THE
INSTABILITY NEEDED FOR FIRES TO POSSIBLY REACH EXTREME GROWTH
POTENTIAL. SEE FIRE DISCUSSION BELOW. HOT DRY CONDITIONS LOOK TO
LIMIT TSRA POTENTIAL AND WILL KEEP DRY FORECAST ATTM WITH NAM AND
NAM KF KEEPING THINGS JUST OFF TO THE NORTHWEST. ALL EYES ARE ON
FRONT JUST NOW MOVING INTO NORTHERN ROCKIES/NW HIGH PLAINS AS GTF
HAS DROPPED FROM 71 AT 00Z TO 34 AT 07Z BEHIND FROPA...AND LOWER 20S
JUST UPSTREAM. THIS COLD AIR SEEMS TO HAVE ENOUGH MOMEMTUM TO FORCE
FRONT SOUTHWARD EVEN WITH FAIRLY STRONG SW FLOW ALOFT AND TIMING
STILL FAIRLY SIMILAR TO LAST NIGHT. THIS BRING FRONT DOWN INTO FAR
SOUTHERN CWA BY MID AFTERNOON WHERE LEE INDUCED CYCLONE ACROSS
NORTHEAST COLORADO LOOKS TO HANG FRONT. LOOKS LIKE EXTREME SOUTHWEST
NEBRASKA MAY REACH INTO 80S AGAIN ON FRIDAY AND THIS WILL AGAIN PUT
THIS AREA IN FIRE RISK WITH STRONGER WINDS AND LOW RH ANTICIPATED
AHEAD OF FRONT. CONVECTION...POSSIBLY STRONG LOOKS VERY POSSIBLE
ALONG FRONT TOMORROW AFTERNOON. NAM AND WRF KF SHOWING THIS JUST
EAST OF CWA WHERE DRY LINE BULGES ALONG COLD FRONT CREATING TRIPLE
POINT. SEEMS AS IF STORMS FORM NEAR THIS BOUNDARY WITH STRONGLY
BACKED EASTERLY FLOW AT SFC JUST NORTH OF FRONT...ISOLATED TORNADOES
COULD BE POSSIBLE. STRONGEST INSTABILITY IN WARM SECTOR DEFINITELY
ACROSS CENTRAL EASTERN NEB. POPS HAVE ACCOUNTED FOR TS ALONG FRONT
AND WILL LEAVE AS IS WITH TEMPS RANGING FROM MID 50S IN THE
NORTHWEST TO MID 80S FAR SOUTHEAST BY MID/LATE AFTERNOON. CONTINUE
TO BACK OFF TEMPS SAT INTO SUNDAY WITH MODELS STILL TRENDING COLDER.
COULD REALLY SEE TEMPS SATURDAY STRUGGLE OUT OF MID 40S NORTHERN
HALF OF CWA....BUT FOR NOW HAVE UPPER 50S SOUTH...UPPER 40S NORTH.
PCPN THREAT CONTINUES TO LOOK MAINLY ACROSS NORTHERN CWA AND POINTS
FARTHER NORTH THROUGH SATURDAY EVENING AS MAIN ENERGY AND MID LEVEL
MOISTURE CONTINUE TO RIDE IN SW FLOW ACROSS WY ROCKIES INTO SOUTH
DAKOTA. CONCERN WITH PTYPE EARLY SAT MORN HOWEVER SREF SHOWING
MIXTURE OF RA/SN/IP IN PLUMES FOR VTN BUT NAM COLDER THAN GFS ATTM.
INTRODUCED MIX IN FAR NW WHERE LLVL PROFILE COOLER IN BUFKIT AND
MORE SUPPORTIVE OF MIX OR CHANGE OVER. BEST PCPN CHANCES LOOK TO BE
SAT NIGHT AS MAIN UPPER TROF MOVES OVER ROCKIES AND MID LEVEL FRONTO
BAND SETS UP ACROSS PANHANDLE. PROFILE SLIGHTLY WARMER IN THE LOWER
LEVELS AND HAVE KEPT LIQUID PCPN IN FOR NOW...AND WILL CONTINUE TO
MONITOR THIS UNCERTAINTY. COOL TEMPS SUNDAY INTO FIRST OF NEXT WEEK
BEFORE NEXT TROF DIGS INTO NW AND PUSHES HIGHER THICKNESSES INTO
PLAINS FOR MIDWEEK.

&&

.FIRE WEATHER...
CRITICAL FIRE CONDITIONS NOT A SLAM DUNK THIS AFTERNOON BUT ENOUGH
INGREDIENTS SEEM TO BE PRESENT TO PLACE NORTHERN CWA IN HEADLINES.
MODELS HAVE NOT HAD HANDLE ON AFTERNOON RH DROPS PAST FEW DAYS AND
BELIEVE RH LEVELS IN THE LOWER TEENS LIKELY FROM PANAHNDLE AND FAR
SOUTHWEST WILL INTO SANDHILLS...WITH NEAR 20 PERCENT IN FAR NORTH
CENTRAL ZONES. RECOVERY STILL LOW AT VTN THIS MORNING. MINUS RMS
MEMBERS...SREF 2M RH PLUMES ALSO HINTED AND THE LOW RH LEVELS OVER
CWA. AS MENTIONED PATTERN RECOG SHOWS RIDGE OVHD AND LLVL THERMAL
RIDGE IN PLACE SO INSTABILITY IN PLACE FOR RAPID FIRE GROWTH
POTENTIAL. MIXING SHOULD BE H7-H6 AND WITH STRONGER H7 WINDS
INDICATED NORTH OF I-80 BY MID AFTERNOON...MOMENTUM XFER SHOULD
ALLOW SOME WIND GUSTS OVER 25 MPH CREATING NEEDED CRITICAL
CONDITIONS FOR RFW TO VERIFY. FUEL STATUS MAPS SHOW FAVORABLE
CONDITIONS AS WELL AND 1 HOUR FUEL BETWEEN YESTERDAYS LOW RH READING
AND TODAYS MAX TEMPS SHOULD BE IN READY TO BURN STATE.

&&

.AVIATION...
    UNRESTRICTED CEILING AND VISIBILITY WILL CONTINUE THROUGH EARLY
FRIDAY. FORECAST SOUNDINGS INDICATE THAT MIXING WILL BE TO NEARLY
600 MB. THEREFORE...BY EARLY AFTERNOON...WIND IN NORTH CENTRAL
NEBRASKA WILL BE 240-260/15-20G25KT. THIS IS REFLECTED IN THE KVTN
TAF. SLIGHTLY LOWER WIND IS EXPECTED IN KLBF...10-12KT WITHOUT MUCH
GUSTINESS.
