AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
354 AM CDT FRI MAY 8 2009

.DISCUSSION...
COLD FRONT IS DIVING SOUTH ACROSS S DAKOTA THIS MORNING...WITH A
WEAK SURF LOW SPINNING OVER THE SOUTHERN PANHANDLE. SURF LOW
PROVIDING ENOUGH LIFT TO INITIATE SOME LIGHT SHOWERS AND A STRIKE
EVERY NOW AND THEN OVER NE CO. THE NEAR ZONAL FLOW TRACKS SHOWERS
TO THE EAST ACROSS SOUTHWEST NEBRASKA. MEANWHILE FURTHER NORTH
AHEAD OF AN ADVANCING COLD FRONT ARE SOME SCT SHOWERS...ALTHOUGH
SHOWING A DIMINISHING TREND OVER THE PAST HOUR.

MAIN CONCERNS ARE WINDS AND POPS TODAY AND ON AND OFF CHANCES FOR
SHOWERS OVER THE WEEKEND AND THE WARM UP TO START NEXT WORK WEEK.

FOR TODAY...SURF LOW WEAKENS BRINGING AN END TO SHOWERS IN THE
SOUTHWEST EARLY THIS MORNING. COLD FRONT WILL TREK SOUTHEAST
ACROSS THE AREA THIS MORNING/AFTN...DRAGGING SOME COOL CANADIAN
AIR WITH IT. A HIGH WILL BUILD IN BEHIND THE COLD FRONT...N TO NW
WINDS PICK UP. MOS GUIDANCE AND MODEL WINDS SHOWING LITTLE
AGREEMENT TO WIND SPEEDS TODAY. NAM/MET HAS MUCH WEAKER WINDS THAN
THE GFS/MAV...WHICH ARE CLOSE TO ADVISORY. HAVE HEDGE TOWARDS
STRONGER WINDS...AS SEEING SOME SUPPORT FROM LATEST RUC. AS FOR
THE SHOWERS...N CENTRAL TO SEE THE BEST CHANCE FOR SHOWERS TO HOLD
TOGETHER. HIGHS TODAY ALSO ON THE TRICKY SIDE AS SOME POCKETS OF
CLEARING ALREADY DEVELOPING OVER THE PANHANDLE. THIS SUGGEST THAT
WE MAY SEE MORE SUN THAN PREVIOUSLY THOUGHT. THIS WILL HELP WARM
UP TEMPS A FEW DEGREES. STILL EXPECT HIGHS TO TOP OUT ABOUT 10
DEGREES BELOW YESTERDAY...IN THE UPPER 50S N TO MID 60S SOUTH.

OVERNIGHT INTO SATURDAY LOOKING DRY AS HIGH PRESSURE BRINGS
SUBSIDENCE ACROSS THE AREA. SAT MORN TO START OUT CHILLY AND MAY
SOME FROST IN THE NORTHWEST. DURING THE DAY...STILL GOING TO BE
COOL...CLOSER TO SEASONAL WITH HIGHS IN THE 60S. SHORT LIVED DRY
SPELL AS HIGHS SLIDES ON TO THE SOUTHEAST AND RETURN SE FLOW TO
BRING UPSLOPE LIFT. COMBINE WITH NOCTURNAL LL JET AND A RETURN OF
POPS IS NEEDED BY SATURDAY NIGHT. ANOTHER TROF TO CROSS THE AREA
ON SUNDAY WITH A BETTER CHANCE OF PRECIP DURING THE
DAY...LINGERING INTO THE NIGHT.

WEAK RIDGING TO START THE WEEK WITH HIGHS SOARING BACK INTO THE
70S FOR MONDAY AND TUESDAY. GFS IS A LITTLE FAST WITH SECONDARY
PUSH OF COLD AIR ON TUESDAY...HOWEVER ONLY NUDGE DOWNWARD A LITTLE
AS SHREF IS A LITTLE SLOWER/WARM. ACTIVE PATTERN CONTINUES FOR THE
WEEK WITH THE TRAIN OF DISTURBANCES TO CROSS THE PLAINS. COMBINED
WITH THE LL JET AND MAY SEE SOME ISOLD SHOWERS DEVELOP WITH EACH
PASSING WAVE. MORE ON THIS IN LATER FORECASTS.

.AVIATION...
GENERALLY VFR.

THE AREA OF RAIN AND THUNDERSTORMS ACROSS SOUTH DAKOTA EARLY THIS
MORNING IS EXPECTED TO MOVE IN A GENERALLY EAST DIRECTION BRUSHING
THE NEBRASKA BORDER. ISOLD POCKETS OF IFR WILL OCCUR WITH
THUNDERSTORMS ALONG THE SRN FLANK. THIS DISTURBANCE SHOULD CLEAR THE
FCST AREA BY 12Z.

THE RAIN ACROSS SOUTHWEST NEBRASKA APPEARS TO BE ANCHORED AND COULD
LAST THROUGH MID MORNING PERHAPS. ALTHOUGH VFR IS EXPECTED IN THIS
AREA OF UNSETTLED WEATHER...LOCALLY IFR CONDITIONS WILL DEVELOP IN
ISOLATED THUNDERSTORMS ACROSS SOUTHWEST NEBRASKA. THESE STORMS
APPEAR TO BE BECOMING MORE ISOLATED AND COULD EXIT THE AREA BY 12Z.

OTHERWISE A COLD FRONT WILL DROP THROUGH WESTERN AND NORTH CENTRAL
NEBRASKA THIS MORNING PRODUCING SCT-BKN030-050 CEILINGS. FLIGHT
CONDITIONS WILL IMPROVE THIS AFTERNOON WITH NEARLY CLEAR SKIES
TONIGHT.
