SOUTH CENTRAL NEBRASKA/NORTH CENTRAL KANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
225 PM CDT THU JUL 26 2001

MAIN CONCERN THIS PACKAGE IS THUNDER CHANCES.

WATER VAPOR SATL PIX THIS AFTERNOON SHOWS A RATHER POTENT VORT MAX
NEAR THE GREAT BASIN. WITH TIME THIS ENERGY SHOULD RUN UP AND OVER
THE HIGH PRESSURE RIDGE SITUATED OVER THE CENTRAL PLAINS. MOISTURE
THOUGH REMAINS AMPLE FLOWING FROM THE SUB-TROPICS. AT THE SURFACE A
STALLED FRONTAL BOUNDARY EXTENDED FROM NORTHERN OKLA TO JUST OFF
THE NEW ENGLAND COAST. NORTH OF THE BOUNDARY HIGH PRESSURE WAS
SITUATED NEAR THE GREAT LAKES WITH A TROF OF LOW PRESSURE
BEGINNING TO SLIDE THRU THE DAKOTAS.

STORMS APPEAR LIKELY TO AFFECT OUR AREA SOMETIME AROUND MIDNIGHT.
AT THAT TIME THE MID LEVEL WAVE...MOST PRONOUNCED AROUND 700MB
APPROACHES THE CWA. OMEGA VALUES SIGNIFICANTLY INCREASE AS THE WAVE
MOVES THRU AN AREA OF STRONG DPVA...AIDED BY FAVORABLE UPPER LEVEL
DIVERGENCE AND MID LEVEL WAA. MODEL QPF HIT THE AREA HARD...BUT
GREATEST PCPN CHANCES WILL PROBABLY BE OVER NRN SECTIONS OF THE
CWA. THE WAVE MOVES QUICKLY THRU THE CWA...SO EXPECT SOME LINGERING
CONVECTION DURING THE MORNING HOURS FRIDAY.

AFTERWHICH THE ETA APPEARS TO INTRODUCE SUBSIDENCE/MID LEVEL Q-VECTOR
INTO THE NEB CWA LATE FRIDAY THRU FRIDAY NIGHT. SO EXPECT CLOUDS TO
DISSIPATE QUICKLY. SOUTH THOUGH...THE ETA HINTS AT MORE CONVECTION
TO FIRE FRIDAY NIGHT OVER OUR KS CWA AND ACTUALLY SUGGEST QPF
AMOUNTS NEAR 6 INCHES OVERNIGHT. THE NGM AND THE AVN ALSO SUGGEST
ACTIVITY TO BE SOUTH...BUT THEIR QPF AMOUNTS LOOK MUCH MORE
REASONABLE THAN THE ETA. SO SMALL POPS OVER OUR KS CWA IS PROBABLY
JUSTIFIED.

MADE SOME MAJOR CHANGES TO THE EXTENDED. HAVE DECIDED TO PULL PCPN
CHANCES ENTIRELY AND BUMP UP TEMPS. THE LATEST AVN RUN REALLY
DIDN'T SHOW ANYTHING TOO COMPELLING TO JUSTIFY LEAVING PCPN CHANCES
GOING THRU WEDNESDAY. ALSO WITH RIDGING FORECAST TO AMPLIFY...HAVE
RAISED TEMPS.

.GID...NONE.
