AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
935 PM CDT WED JUN 6 2007

.UPDATE...
UPDATED THE FORECAST FOR TIMING AND LOCATION OF CONVECTION...AS WELL
AS TO ALLOW THE WIND ADVISORY TO EXPIRE.

00Z OAX SOUNDING CONTINUE TO SHOW A STRONG CAPPING INVERSION...
HOWEVER FORCING FOR ASCENT IS VERY STRONG THROUGHOUT MUCH OF THE
TROPOSPHERE AS A RESULT OF THE DEEP UPPER AND SURFACE LOW.  DRYLINE
WAS ANALYZED FROM JUST WEST OF MC COOK TO NEAR AINSWORTH...AND
SEVERE CONVECTIVE LINE IS ALONG OR A FEW MILES EAST OF DRYLINE.
CELL MOTION IS NORTHEAST AROUND 50 KNOTS WITH LINE MOTION ENE AT
25-30 KNOTS.  THIS PUTS THE LEADING EDGE INTO KNOX COUNTY.  FOR
DETAILS ON SEVERE POTENTIAL...SEE THE RECENT WARNING DECISION UPDATE
FROM OAX...OMAAWUOAX.

OTHERWISE SOME DECOUPLING HAS TAKEN PLACE AS WIND GUSTS ARE SLOWLY
LOWERING.  SOME CONCERN FOR INCREASING GUSTS WITH 70 KNOT LOW LEVEL
JET AND THE SURFACE LOW DEEPENING TO 975 MB.  HOWEVER MOST SITES ARE
ALREADY BELOW ADVISORY CRITERIA...AND IT DOES NOT LOOK LIKELY THAT
SITES WILL BE ABLE TO MAINTAIN SUSTAINED 30 MPH WINDS THROUGHOUT THE
NIGHT.

&&

.DISCUSSION...
PREVIOUS DISCUSSION
FORECAST CONCERNS CENTER AROUND STRONG WINDS THIS EVENING AND TIMING
OF STORMS TONIGHT.

ALL OF THE CWA APPEARS TO BE IN THE WARM SECTOR AT 19Z WITH STRONG
SOUTH WINDS ACROSS THE AREA. WIND GUSTS IN THE 40-50 MPH RANGE EARLY
THIS AFTERNOON AND EXPECT THE WINDS TO CONTINUE INTO THE EVENING.
12Z GFS BUFKIT DATA HAS WIND GUSTS DIMINISHING AFTER 03Z ALTHOUGH
SUSTAINED STILL IN THE 20-30KT RANGE. WILL LEAVE ADVISORY EXPIRATION
AT 03Z FOR NOW AND LET EVENING SHIFT EXTEND IF NECESSARY.

NEXT QUESTION WILL BE TIMING OF STORMS INTO THE AREA TONIGHT.
VISIBLE SATELLITE SHOWING CONVECTION DEVELOPING OVER WY IN LINE WITH
LATEST SPC DISCUSSION. IF THINGS DEVELOP AS EXPECTED...LOOKS LIKE
A LATE NIGHT EARLY MORNING EVENT FOR THE CWA AS LINE DEVELOPS IN THE
WEST AND APPROACHES THE AREA TOWARD MIDNIGHT. SOME LINGERING POPS
FOR THE EASTERN CWA THURSDAY MORNING THEN DRY AND COOLER AFTER THAT
INTO FRIDAY. NEXT CHANCE OF RAIN RETURNS TO THE AREA SATURDAY NIGHT
WHICH IS IN LINE WITH CURRENT FORECAST. PRIMARY CHANGE IN THE
EXTENDED PERIOD WAS TO TREND TOWARD WARMER TEMPERATURES SUNDAY AND
BEYOND AS UPPER RIDGE BUILDS AHEAD OF NEXT WESTERN TROUGH.   DF

&&

.AVIATION...

STRONG LOW LEVEL WINDS WILL BE THE PRIMARY AVIATION CONCERN THROUGH
EVENING...THEN CHC OF TSRA.  FBY PROFILER SHOWING 65KTS ON THE LOWER
LEVEL WNDS.  OAX VWP HAS 40KTS AT 2K FT.  BUFKIT SOUNDINGS SHOW
STRONG S WINDS THRU THE EVENING AND HAVE MENTIONED STRONG WND GUSTS
IN THE TAFS AND SFC WNDS IN THE TWBS.  TSRA WILL BE POSSIBLE IN THE
OFK AREA BY LATE EVENING AND OVERNIGHT AT OMA/LNK.  HAVE PROBS IN VS
LIKELY DUE TO UNCERTAINTY AND COVERAGE.  CZ
