AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
256 PM CDT MON SEP 6 2010

.SYNOPSIS...

WOW...WHAT A DIFFERENCE A DAY MAKES. TEMPERATURES AS OF 3 PM CDT ARE
RUNNING 30 TO 40 DEGREES COOLER THAN YESTERDAYS READINGS THIS TIME. A
VIGOROUS UPPER LEVEL TROUGH OF LOW PRESSURE CONTINUES TO LIFT ACROSS
SRN SD ATTM. THIS FEATURE FORCED A COLD FRONT THROUGH THE FORECAST
AREA EARLIER THIS MORNING RESULTING IN STRONG NORTHWESTERLY WINDS
LIGHT RAIN SHOWERS AND MUCH COOLER TEMPERATURES. THE UPPER AIR
PATTERN THIS MORNING WAS INDICATING THE BEFORE MENTIONED TROUGH
EXTENDING FROM ERN MT INT NERN COLORADO. ANOTHER SHORTWAVE WAS
TRAVELING DOWN THE PACIFIC COAST OF CANADA AND A PERSISTENT CLOSED
LOW WAS PRESENT OVER SRN PORTIONS OF HUDSON BAY. HIGH PRESSURE WAS
ANCHORED OVER THE GULF OF MEXICO AND THE WESTERN ATLANTIC.

&&

.DISCUSSION...

SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT...NEAR TERM FORECAST
CHALLENGES DEAL WITH TEMPERATURES TONIGHT...PARTICULARLY FROST
POTENTIAL IN THE EASTERN PANHANDLE AND PLATTE RIVER VALLEYS. THE
LATEST MET GUIDANCE HAS COME IN COOLER THIS MORNING WITH 32 DEGREES
FOR LBF...28 FOR AIA...31 FOR CDR AND 33 FOR OGA. THE MAV GUIDANCE
IS SLIGHTLY WARMER...HOWEVER LIGHT WNW DRAINAGE WINDS...HIGH
PRESSURE OVHD AND DRY AIR WILL FAVOR TEMPS MORE TOWARD THE MET
GUIDANCE FOR TONIGHT. ATTM...DO NOT SEE ANY REASON TO DEVIATE FROM
THE MET GUIDANCE WHICH WILL NECESSITATE A FROST ADVISORY...ROUGHLY
FOR THE PANHANDLE AS WELL AS KEITH AND LINCOLN
COUNTIES...PARTICULARLY IN THE PLATTE RIVER VALLEY WHERE COLD
DRAINAGE WILL BE MOST PRONOUNCED. IF 32 DEGREES IS REACHED FOR LBF
TUESDAY MORNING...IT WOULD BEAT THE RECORD LOW OF 35 SET BACK IN
1898. AFTER 98 ON SUNDAY...ITS HARD TO BELIEVE WE ARE LOOKING AT
RECORD LOWS TONIGHT. WELCOME TO FALL.

ON TUESDAY...WINDS WILL QUICKLY SHIFT TO THE SOUTH AS HIGH PRESSURE
MOVES EAST. DECENT WAA WILL COMMENCE AS RIDGING BUILDS ACROSS THE
CENTRAL CONUS AND THE EXITING COLD FROPA FROM EARLIER TODAY LIFTS
NORTH AS A WARM FRONT. MOISTURE WILL INCREASE AS WELL TUESDAY NIGHT
AS THE REMNANTS OF HERMINE LIFTS NORTH INTO THE SRN PLAINS. FOR
WEDNESDAY THROUGH THURSDAY...THE FORECAST REMAINED UNCHANGED WITH
PRECIPITATION CHANCES CONTINUING. SWRLY FLOW ALOFT...AND ABUNDANT
LOW LEVEL MOISTURE WILL BE FAVORABLE FOR THUNDERSTORMS. MID LEVEL
WARM AIR ADVECTION WILL AID IN INITIATION WEDNESDAY NIGHT...FOLLOWED
BY A STRONG MID LEVEL DISTURBANCE THURSDAY AND THE UPPER LEVEL
TROUGH TRACKING ACROSS THE NORTHERN PLAINS ON FRIDAY. HIGHS WILL
GENERALLY BE IN THE 80S WITH LOWS IN THE 50S AND LOWER 60S THANKS TO
THE LOW LEVEL MOISTURE.

LONG TERM...FRIDAY THROUGH MONDAY...GOOD MODEL CONSISTENCY NOTED
THIS MORNING WHICH LENDS BETTER CONFIDENCE IN THE OUTER PERIODS.
MAIN CHANGE WAS TO EXTEND PRECIPITATION CHANCES INTO FRIDAY EVENING
BASED ON THE SLOWER TIMING OF AN EXITING TROUGH OF LOW PRESSURE
FRIDAY NIGHT. FOR FRIDAY...A SURFACE TROUGH OF LOW PRESSURE WILL
TRACK ACROSS THE FORECAST AREA WITH AN H5 TROUGH EXPECTED TO MOVE
THROUGH THE AREA 6 TO 12 HOURS LATER. AM EXPECTING THE SURFACE
TROUGH TO LIGHT UP WITH CONVECTION FRIDAY AFTERNOON AS IT TRACKS
INTO 60+ DEW POINTS ACROSS THE CENTRAL AND ERN CWA. THIS ACTIVITY
WILL LIFT ACROSS THE EASTERN CWA FRIDAY EVENING EXITING THE AREA
LATER FRIDAY NIGHT. WESTERLY WINDS AND MUCH DRIER AIR WILL FILTER
INTO THE AREA BEGINNING SATURDAY WITH SLIGHTLY COOLER TEMPS AND
WESTERLY WINDS. THE H5 PATTERN WILL REMAIN ZONAL THROUGH THE END OF
THE PERIOD WHICH WILL FAVOR DRY CONDS AS LOW LEVEL MOISTURE REMAINS
OFF TO THE EAST OF THE FORECAST AREA. HIGHS WILL BE IN THE UPPER
70S/LWR 80S WITH LOWS IN THE 40S/50S WHICH IS SEASONAL FOR THIS TIME
OF YEAR.

&&

.AVIATION...

NORTHWEST WINDS CONTINUE TO BLOW AT 20 TO 35 KTS THROUGH THE EARLY
EVENING HOURS. GENERALLY VFR CONDITIONS WITH POCKETS OF MVFR CIGS
LINGER EARLY TONIGHT...THEN GIVE WAVE TO CLEAR SKIES. HIGH PRESSURE
WILL THEN BUILD INTO THE REGION BY MORNING WITH LIGHT NORTHWEST
WINDS AND COLD TEMPS. THESE COLD TEMPS WILL RESULT IN AREAS OF FROST
BY EARLY MORNING...ESPECIALLY ON GRASS RUNWAYS IN FAVORED LOW LYING
AREAS OF THE NEB PANHANDLE AND THE PLATTE RIVER VALLEY. VFR
CONDITIONS CONTINUE TOMORROW WHILE WINDS SLOWLY BACK TO THE SOUTH. &&
