AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
250 PM CDT SUN AUG 26 2012

.SYNOPSIS...

    AT 19Z...HAND ANALYSIS OF THE MSL DATA SHOWED A FRONT ACROSS
SOUTH DAKOTA FROM ABOUT MOBRIDGE TO NEAR PINE RIDGE. IN NEBRASKA...A
BOUNDARY WAS INDICATED ACROSS THE PANHANDLE WITH SURFACE MOISTURE
CONVERGING ALONG IT. THE SATELLITE DERIVED PRECIPITABLE WATER SHOWED
23-25MM POOLING IN THE AREA OF THE SURFACE TROUGH AND ALSO LIFTED
INDICES OF -3C TO -5C. IN THE VISIBLE IMAGERY...CUMULUS DEVELOPMENT
WAS OCCURRING ALONG THE BOUNDARY FROM PINE RIDGE TO JUST EAST OF
ALLIANCE AND SIDNEY.
&&

.SHORT TERM...TONIGHT THROUGH MONDAY.

    IN WESTERN NEBRASKA...SOME CONVECTION WILL PROBABLY DEVELOP IN
THE FAVORABLE MOISTURE ALONG THE SURFACE TROUGH/DRY LINE OVER THE
PANHANDLE THIS EVENING. WITH SURFACE DEWPOINTS IN THE 50S...THE LOW
LEVEL MOISTURE IS MARGINAL FOR SIGNIFICANT PRECIPITATION. SOME
MENTION OF THUNDERSTORMS IS APPROPRIATE FOR THE PANHANDLE AND THE
WESTERN SANDHILLS THOUGH WE WILL KEEP THE PROBABILITY BELOW 30
PERCENT. WITH THE SURFACE TROUGH CONTINUING OVER THE NEBRASKA
PANHANDLE AND THE CENTER OF THE UPPER HIGH OVER CENTRAL
COLORADO...SOME MENTION OF THUNDERSTORMS WOULD BE APPROPRIATE FOR
THOSE SAME AREAS AGAIN MONDAY.

    IN OTHER AREAS...THERE IS A POSSIBILITY OF FOG AGAIN TONIGHT.
WITH THE LIGHT EAST TO SOUTHEAST WIND AND HIGH SURFACE DEWPOINTS...
CONDITIONS ARE FAVORABLE FOR FOG. THEREFORE...WE WILL INCLUDE PATCHY
FOG IN THE FORECAST FOR CENTRAL AND SOUTHWEST NEBRASKA TONIGHT AND
EARLY MONDAY.

.MEDIUM AND EXTENDED RANGE...MONDAY NIGHT THROUGH SUNDAY.

    AS THE UPPER HIGH CONTINUES TO BUILD TO THE NORTHEAST ONTO THE
CENTRAL PLAINS...THE CHANCES OF PRECIPITATION DECREASE THROUGH THE
REST OF THE WEEK. THEREFORE...A DRY FORECAST IS APPROPRIATE THROUGH
AT LEAST THE END OF THE WEEK WITH VERY WARM TEMPERATURES.
&&

.AVIATION...

    VFR CONDITIONS TO PREVAIL ACROSS MUCH OF THE FORECAST REGION
THROUGH THE TAF FORECAST PERIOD.  MODEL GUIDANCE STILL INDICATES THE
POTENTIAL OF THUNDERSTORM DEVELOPMENT ACROSS THE EASTERN PANHANDLE
OF NEBRASKA LATE THIS AFTERNOON/EVENING.  MODEL SOUNDINGS WOULD
SUGGEST HIGH BASED STORMS CAPABLE OF MARGINAL HAIL...AND STRONG
ERRATIC WIND.  OTHERWISE...MODEL GUIDANCE IS HINTING AT A RETURN OF
GROUND FOG AT THE KLBF TERMINAL FROM 27.09Z-27.15Z...FORECAST
CONFIDENCE OF LOW FOG DEVELOPMENT IS LESS THAN 20 PERCENT...SO WILL
LEAVE OUT FOR NOW.
&&

.LBF WATCHES/WARNINGS/ADVISORIES...NONE.

SHORT THROUGH EXTENDED RANGE...SPRINGER
AVIATION...JACOBS
