AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
1120 AM CDT SUN MAY 23 2010

.DISCUSSION...
THE SFC COLD FRONT IS ALONG A KSUX-KHSI LINE AS OF 16Z...AND HAS
SLOWED IT SE PACE JUST A BIT SINCE 12Z. THE 12Z KLBF RAOB REVEALED
SHALLOW MOISTENING WITHIN THE FRONTAL INVERSION NEAR 800-HPA...BUT
MUCH LESS SIGNIFICANTLY THAN THE 06Z AND 12Z NAM WOULD SUGGEST.
THIS IS REFLECTED IN A 100 MILE WIDE SWATH OF BKN-OVC CIGS BEHIND
THE SFC FRONT...WHICH ARE MAKING THEIR WAY WEST A BIT...BUT ALSO
THINNING SOME WITH TIME. TEMPS AS OF 16Z ARE RUNNING SOME 5-10 F
WARMER THAN THE GOING FCST...WHICH IS INDICATIVE OF THE BETTER-
THAN-EXPECTED INSOLATION. A 75/25 BLEND OF THE 00Z GFS AND 09Z
SREF TEMP FIELDS MATCHES BETTER TO REALITY...AND TAKES THE FCST
AREA WELL INTO THE 70S THIS AFTN AS MODEL SOUNDINGS WOULD SUGGEST.
THE FCST WILL BE UPDATED TO FOLLOW THAT THINKING.

THIS EVENING...THE 09Z SREF AND 12Z GFS REMAIN CONSISTENT IN RAPID
WARM/MOIST AIR ADVECTION CENTERED ON THE I-80 CORRIDOR AS EARLY AS
03Z. PROG SOUNDINGS SUGGEST A NARROW WINDOW FOR SFC-BASED UPDRAFTS
IF RICH LOW LVL MOISTURE /LOWER 60S SFC DEW POINTS/ CAN WORK INTO
THE WARM FRONTAL ZONE BY THAT TIME...SO THAT WILL BE SOMETHING TO
WATCH. EVEN IF THAT DOESN/T HAPPEN THOUGH...THE 50-60KT LLJ WILL
FOLLOW THE ELEVATED INSTABILITY AXIS NORTH WITH A HAIL THREAT
OVERNIGHT. BUT NO MODELS SHOW CONVECTION IN SOUTHWEST NE PRIOR TO
00Z SO WE WILL RETAIN A DRY FCST TODAY.

&&

.AVIATION...
MOST OF WESTERN AND NORTH CENTRAL NE WILL EXPERIENCE VFR CIGS AND
VIS TODAY...THOUGH SOME VFR/MVFR CIGS FROM 2000-6000 FT AGL WILL
EXIST AT TIMES THRU 00Z ALONG AND EAST OF HIGHWAY 83. WINDS WILL
SHIFT AROUND TO THE EAST...AND A WARM FRONT WILL MOVE NORTH TONIGHT.
THIS WILL LIKELY INDUCE TSRA OVER MUCH OF THE AREA...WITH MODERATE
POTENTIAL FOR IFR IMPACTS AT LBF AND/OR VTN.

&&

.HYDROLOGY...
THE NORTH PLATTE RIVER ABOVE LAKE MCCONAUGHY CONTINUED SHOWING
ELEVATED LEVELS. SINCE THE LEVELS ARE NOT DUE TO EXCESSIVE RAINFALL
BUT DUE TO INCREASED RELEASES FROM UPSTREAM RESERVOIRS. SINCE THERE
IS STILL A SLIGHT RISK OF THE STAGE LEWELLEN REACHING THE FLOOD
THRESHOLD...WE WILL NOT TAKE ACTION ON THE CURRENT FLOOD WARNING
UNTIL THE FORECAST SHOWS A CLEAR TREND DOWNWARD. THE CURRENT
FORECAST INDICATES THAT THE LEVEL WILL CREST THIS MORNING AND BEGIN
TO FALL.

&&

.PREV DISCUSSION... /ISSUED 346 AM CDT SUN MAY 23 2010/

DISCUSSION...
MODELS CREATE DISPARITIES THAT LEAD TO DIFFERENT SOLUTIONS IN THE
NEAR TERM FROM POPS...QPF TO TEMPERATURES. FORECAST IS TRENDED
TOWARD THE NAM SOLUTION WHERE FORECAST CHALLENGE IS POPS. THE NAM
IS COOLER TODAY WHERE LESS EXTENSIVE CLOUDINESS WILL RESULT IN
BETTER HEATING AND USED BLEND OF GUIDANCES TODAY AND TONIGHT AS
GUIDANCE SHOWS UP TO A TEN DEGREE SPREAD. THE LARGE SCALE PATTERN
REMAINS THE SAME THROUGH MONDAY WITH TROUGH IN THE WEST AND
RIDGING IN THE EAST. SOUTHWEST FLOW ALOFT CONTINUES TODAY WITH
FRONTAL BOUNDARY TO RETURN NORTH TONIGHT SO LIMITED POPS UNTIL
THIS EVENING. THE CONVECTION DEVELOPS ACROSS FAR SOUTHWEST OUT OF KANSAS
NEAR THE FRONT THIS EVENING. AS THE H85 SOUTHERLY JET STRENGTHENS
TO AROUND 50 KNOTS THE BOUNDARY IS PUSHED NORTH WITH THUNDERSTORMS
TO BECOME ELEVATED OVERNIGHT. THE 06Z RUN IS A BIT DRIER AND MORE
NORTH THROUGH TODAY WITH LOW CONFIDENCE IN HOW THUNDERSTORMS WILL
DEVELOP AS STABLE CONDITIONS EXIST THROUGH 03Z THEN INSTABILITY
INCREASES WITH STORMS THAT DO FORM TO MOVE NORTH QUICKLY.

SUNDAY NIGHT INTO MONDAY THE AREA OF LOW PRESSURE FORMS IN
NORTHEAST COLORADO AND LIFTS NORTHEAST DURING THE EVENING. THIS
APPEARS TO BE THE BEST TIME FRAME FOR ORGANIZED DYNAMICS AS UPPER
LOW REORIENTATES AND LIFTS NORTHEAST THROUGH THE EVENING PUSHING
THE COLD FRONT EAST ACROSS THE FORECAST AREA FROM 00Z TO 06Z. GOOD
SUBSIDENCE IN THE WAKE OF THE EXITING SYSTEM WITH SKY COVER
DECREASED. WINDS WILL BE PROBLEMATIC ON MONDAY AS SYSTEM DEEPENS
TO THE WEST AND PRESSURE GRADIENT INCREASES EAST FOR SURFACE WINDS
TO INCREASE. WIND ADVISORY LIKELY NEEDED AS LAPSE RATES STEEPEN AND
TEMPERATURES CLIMB INTO THE 80S. RAISED POPS ON MONDAY AS SYSTEM
ORGANIZES AND COLD FRONT PUSHES EAST. NO CAP EVIDENT AT 21Z WITH
SUBSTANTIAL SHEAR FOR STORMS AS STRONG COLD FRONT MOVES
ACROSS...EXITING EAST AROUND 06Z.

MONDAY NIGHT THROUGH THURSDAY FEW CHANGES MADE EVOLUTION OF SYSTEM
IN QUESTION TO START DROPPING POPS. GFS LOOKS TO BE HAVING
FEEDBACK PROBLEMS TO MAKE CHANGES BASED ON THIS MODEL.

528 AM CDT SUN MAY 23 2010 /428 AM MDT SUN MAY 23 2010/

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

.DAY ONE...TODAY AND TONIGHT.

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS TONIGHT IN WESTERN
AND NORTH CENTRAL NEBRASKA. THE FRONT IS EXPECTED TO MOVE
NORTHWARD INTO SOUTHERN NEBRASKA TONIGHT. SCATTERED THUNDERSTORMS
ARE EXPECTED WITH THE FRONT...AND THE GREATEST RISK OF SEVERE
THUNDERSTORMS WOULD BE SOUTH OF THE FRONT OR ALONG AND SOUTH OF
INTERSTATE HIGHWAY 80. HAIL IS THE PRIMARY RISK WITH THE
STORMS...THOUGH THERE IS A SMALL CHANCE OF DAMAGING WIND.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.

ACTIVE WEATHER IS EXPECTED TO CONTINUE THROUGH THE WEEK AS FRONTS
MAKE THEIR WAY ACROSS THE CENTRAL PLAINS.

THERE IS A RISK OF SEVERE THUNDERSTORMS AGAIN MONDAY AS THE WARM
FRONT MOVES ACROSS THE NORTHERN PLAINS AND A COLD FRONT INTERCEPTS
THE UNSTABLE AIR LEFT BY THE WARM FRONT. THE GREATEST RISK OF
SEVERE THUNDERSTORMS WILL BE EAST OF STATE HIGHWAY 61 AND NORTH OF
INTERSTATE HIGHWAY 80. WIND PROFILES AND LOW LEVEL INSTABILITY
WILL FAVOR THE DEVELOPMENT OF SUPER CELLS...BUT THE PRIMARY RISK
IS LARGE HAIL AND DAMAGING WIND.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED TONIGHT AND MONDAY.
