AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
317 AM CDT MON JUL 10 2006

.DISCUSSION...MAIN FORECAST CHALLENGE CENTERS AROUND CHANCES OF
PRECIPITATION TODAY AND TONIGHT. KUEX DOPPLER RADAR SHOWING
WIDESPREAD LOW LEVEL CONVECTIVE ACTIVITY OVER SOUTHEAST PORTIONS OF
THE FORECAST AREA WITH A SECONDARY...BUT MUCH SMALLER...CLUSTER OF
ACTIVITY OVER BUFFALO AND DAWSON COUNTIES. AIRMASS IS RATHER
TROPICAL WITH SURFACE DEW POINTS RANGING FROM THE MID 60S TO AROUND
70 DEGREES. THE REMAINDER OF THE AIRMASS IS VERY WARM AND MOIST WITH
FREEZING LEVELS AROUND 17K AND PRECIPITABLE WATER VALUES NOW
EXCEEDING 1.5 INCHES. MOST STORMS THAT ARE DEVELOPING AT THIS TIME
ARE VERY EFFICIENT RAIN PRODUCERS WITH DOPPLER ESTIMATES REACHING UP
TO 2 INCHES IN CERTAIN LOCATIONS...HOWEVER...NO PROBLEMS CURRENTLY
NOTED WITH HEAVY RAINFALL IN THE AREA.

A RELATIVELY COOLER AND WET DAY IS ON TAP FOR TODAY AS PRECIPITABLE
WATER VALUES CONTINUE TO GET PUMPED UP OVER SOUTH CENTRAL NEBRASKA
AND NORTH CENTRAL KANSAS AHEAD OF AN UPPER LEVEL TROUGH APPROACHING
FROM THE FRONT RANGE OF THE ROCKIES. AN EXTREMELY MOIST AIRMASS WILL
BE IN PLACE AS THE UPPER TROUGH AND ASSOCIATED DYNAMICS PASS ACROSS
THE REGION AROUND MIDDAY. MODERATE LOW LEVEL MOISTURE CONVERGENCE
WILL LEND TO THE UPPER DYNAMICS FOR WIDESPREAD SHOWER AND
THUNDERSTORM DEVELOPMENT THROUGHOUT THE DAY. BECAUSE OF THIS...HAVE
GONE WITH LIKELY POPS ALL LOCATIONS WITH CHANCES OF RAIN DECREASING
FROM WEST TO EAST LATE THIS AFTERNOON AS THE MAIN DYNAMICS
ASSOCIATED WITH THE UPPER TROUGH PASS TO THE EAST.
ADDITIONALLY...CONSIDERABLE CLOUD COVER WILL KEEP HIGH TEMPERATURES
DOWN IN THE UPPER 70S TO LOWER 80S.

CHANCES OF PRECIPITATION WILL WIND DOWN OVERNIGHT TONIGHT AS THE
UPPER TROUGH SLOWLY PASSES TO THE EAST AND A DRIER
WEST-NORTHWESTERLY FLOW BEGINS TO DEVELOP OVER THE CENTRAL PLAINS.
HOWEVER...SLIGHT CHANCES OF SHOWERS AND THUNDERSTORMS WILL CONTINUE
INTO TUESDAY MAINLY OVER THE EASTERN FORECAST ZONES. THESE CHANCES
WILL DIMINISH GREATLY IN THE LATE AFTERNOON AND EARLY EVENING HOURS
AS A MUCH MORE SUBSIDENT NORTHWEST FLOW DEVELOPS ALOFT IN RESPONSE
TO HIGH PRESSURE RIDGING OVER THE ROCKY MOUNTAINS. CLEARING SKIES
AND BUILDING HIGH PRESSURE WILL CAUSE HIGH TEMPERATURES ON TUESDAY
TO RISE ABOVE VALUES THAT WILL BE SEEN TODAY.

ON TUESDAY NIGHT...THE UPPER LEVEL RIDGE AXIS WILL PASS ACROSS OUR
AREA AND BRING FAIR SKIES WITH WARMER OVERNIGHT LOW TEMPERATURES. ON
WEDNESDAY...THE UPPER RIDGE AXIS WILL BE JUST TO OUR EAST AND
DAYTIME HIGH TEMPERATURES WILL JUMP A GOOD 10 DEGREES FROM VALUES
SEEN ON TUESDAY. HIGH TEMPERATURES WILL GENERALLY BE IN THE MID TO
UPPER 90S WITH DRY CONDITIONS EXPECTED.
