Hail in Nebraska, May 28, 2005

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
320 AM CDT SAT MAY 28 2005

.DISCUSSION...MAIN PROBLEMS SURROUND THUNDERSTORM CHANCES TODAY AND
TONIGHT ALONG WITH POTENTIAL SEVERE WEATHER.  06Z SURFACE ANALYSIS
SHOWERS RELATIVELY DRY LOW LEVEL AIR ACROSS MUCH OF THE FORECAST
AREA WITH DEWPOINTS IN THE MID 30S TO MID 40S.  MOISTURE IS NOT TOO
FAR AWAY WITH LOWER TO MID 50S DEWPOINTS IN SOUTHERN KANSAS AND
NORTHERN OKLAHOMA.  THE 00Z NAM IS ADVERTISING AN INCREASE IN LOW
LEVEL MOISTURE TODAY ACROSS THE CWFA AS A WARM FRONT BECOMES
ESTABLISHED ACROSS THE AREA.  THERE SHOULD BE ENOUGH INSTABILITY AND
DEEP LAYER SHEAR FOR SOME STORMS TO DEVELOP AND BECOME SEVERE WITH
THE MAIN THREATS LARGE HAIL AND DAMAGING WINDS.  THE LACK OF LOW
LEVEL SHEAR SHOULD MINIMIZE THE TORNADO THREAT...HOWEVER ANY STORMS
NEAR THE LOW LEVEL BOUNDARY WILL HAVE TO STILL BE WATCHED CLOSELY.

THE BETTER CHANCES OF THUNDERSTORMS SHOULD GRADUALLY SHIFT OUT OF
THE CWA LATER TONIGHT AS THE LOW LEVEL JET TURNS MORE
WESTERLY...HOWEVER WILL NOT END THUNDERSTORM CHANCES UNTIL BOTH THE
850 MB AND SURFACE FRONTS PASS ON SUNDAY.  ONE LIMITING FACTOR TO
THE SEVERE WEATHER CHANCES TODAY COULD BE HOW MUCH MOISTURE WILL
ACTUALLY RETURN WITH THE 00Z GFS KEEPING THE DEEPER MOISTURE
CONFINED TO KANSAS AND FAR SOUTHERN NEBRASKA.

THE RIDGE IN THE WESTERN UNITED STATES APPEARS TO STILL BREAK DOWN
BY MONDAY WITH THE LEAD SHORTWAVE ENERGY MAKING IT INTO THE CENTRAL
PLAINS BY TUESDAY.  DECIDED TO ADJUST POPS A BIT ON TUESDAY TO BRING
IN THE RAIN CHANCES EARLIER...OTHERWISE LEFT MOST OF THE EXTENDED
ALONE.
