AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
300 AM CDT WED AUG 25 2004

.DISCUSSION...CONVECTION ONCE AGAIN MAKING ITS WAY THROUGH FORECAST
AREA EARLY THIS MORNING. ADDITIONAL CONVECTION DEVELOPING TO THE
WEST OF FORECAST AREA. WILL HAVE TO HAVE SOME POPS AT LEAST THROUGH
PART OF THE MORNING TO COVER THIS.

EXPECT THERE TO BE CLEARING EARLY TODAY AND WITH A GOOD AMOUNT OF
SUN TEMPERATURES WILL WARM WELL TODAY. SURFACE TROUGH CONTINUES TO
SIT OVER THE AREA TODAY AND TONIGHT BEFORE FINALLY MOVING EAST ON
THURSDAY. WITH SOME LINGERING MOISTURE YET THIS AFTERNOON AND
EVENING ISOLATED THUNDERSTORMS COULD DEVELOP ALONG THIS TROUGH IN
THE EASTERN PART OF THE FORECAST AREA.

A WEAK SHORT WAVE MOVES THROUGH THE PLAINS ON THURSDAY. EVEN THOUGH
THE SURFACE FRONT IS IN THE VICINITY WILL LEAVE THE FORECAST DRY.
EVEN THE USUALLY WET GFS IS FAIRLY DRY AND FEEL THAT THE LOWER
LAYERS WILL BE DRY ENOUGH THAT THERE WILL NOT BE PRECIPITATION.

AN UPPER LEVEL TROUGH MOVES ONTO THE WEST COAST...PROGRESSING ACROSS
THE ROCKIES AND MOVING INTO THE PLAINS. AHEAD OF THE TROUGH A COUPLE
OF SHORT WAVES MOVE INTO THE PLAINS FRIDAY AND SATURDAY. A SURFACE
LOW PRESSURE SYSTEM DEVELOPS IN THE SOUTHERN PLAINS WITH HIGH
PRESSURE IN THE NORTHERN PLAINS. A FAIRLY STRONG EAST/NORTHEAST
SURFACE GRADIENT SETS UP STARTING THURSDAY NIGHT. WITH THE
UPSLOPE...ENOUGH MOISTURE AND UPPER LEVEL SUPPORT EXPECT THAT THERE
WILL BE SHOWERS AND THUNDERSTORMS MUCH OF THE DAY. TEMPERATURES WILL
ALSO BE COOLER DUE TO THE CLOUDS AND NORTHEAST WINDS.

THE HIGH PRESSURE TO THE NORTH WILL SINK SOUTHWARD SATURDAY AND
SUNDAY. THIS WILL KEEP TEMPERATURES DOWN MOSTLY FOR SATURDAY...BUT
TO A LESSER EXTENT ON SUNDAY.

EARLY NEXT WEEK A BROAD RIDGE BUILDS BACK UP IN THE WESTERN U.S.
THIS WILL BRING A WARMING TREND AFTER THE COOL WEEKEND.
