AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
327 AM CDT WED AUG 26 2015

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 323 AM CDT WED AUG 26 2015

THE MAJORITY OF THE NEXT 24 HOURS WILL REMAIN FAIRLY QUIET WITH THE
CONTINUED PRESENCE OF THE UPPER LEVEL RIDGE BUILDING ALONG THE FRONT
RANGE. AT THE SURFACE...LOW PRESSURE ALONG THE FRONT RANGE WILL AIDE
IN A TIGHTENED PRESSURE GRADIENT AND INCREASED WARM AIR ADVECTION
ACROSS THE AREA. HIGH TEMPERATURES SHOULD BE SLIGHTLY WARMER THAN
YESTERDAY WITH 80S TO MID 90S FOR FORECAST HIGHS. SOUTH SOUTH EAST
BREEZES WILL ALSO INCREASE UNDER THE PRESSURE GRADIENT WITH GUSTS
APPROACHING 20 KTS AT TIMES.

A PATTERN CHANGE IS IN STORE BY WEDNESDAY NIGHT...AS AN UPPER LEVEL
DISTURBANCE ROUNDING THE TOP OF THE RIDGE APPROACHES THE CENTRAL
PLAINS. THIS SYSTEM WILL EJECT THE SURFACE LOW ACROSS THE
PLAINS...WHICH WILL GENERATE A LOW LEVEL JET OVERNIGHT INTO THURSDAY
MORNING. WHILE THE NOSE OF THE LOW LEVEL JET REMAINS NORTH OF THE
FORECAST AREA. IT REMAINS CERTAINLY POSSIBLE SOME SHOWER AND
THUNDERSTORM ACTIVITY COULD CREEP INTO NORTHEASTERN ZONES OF THE
FORECAST AREA. SEVERE WEATHER IS NOT EXPECTED.

.LONG TERM...(THURSDAY THROUGH TUESDAY)
ISSUED AT 323 AM CDT WED AUG 26 2015

AN UPPER LOW MOVES OVER AND BREAKS DOWN THE RIDGE ACROSS THE AREA ON
THURSDAY. A SURFACE LOW ON THE HIGH PLAINS WITH A COLD FRONT TO THE
SOUTH MOVES TOWARD THE FORECAST AREA THURSDAY MORNING. THERE IS A
SMALL CHANCE FOR A FEW THUNDERSTORMS MAINLY NORTH IN THE FORECAST
AREA DURING THE MORNING. DURING THE AFTERNOON AND EVENING THE FRONT
MOVES THROUGH MUCH OF THE FORECAST AREA WITH THUNDERSTORM CHANCES
INCREASING THROUGH THE AFTERNOON AND BEST DURING THE EVENING HOURS.
THERE IS SURFACE CAPE OF OVER 4000 J/KG DURING THE AFTERNOON AND
EARLY EVENING...THEN DROPS OFF DURING THE EVENING HOURS. MODELS HAVE
CLEARED MUCH OF THE THUNDERSTORMS OUT OF THE AREA BY FRIDAY
MORNING...BUT THERE IS A LITTLE BIT OF WRAP AROUND THAT COULD CLIP
THE NORTHEAST DURING THE MORNING.

BY FRIDAY AFTERNOON THERE IS A SURFACE HIGH THAT SETTLES INTO THE
AREA THROUGH SATURDAY NIGHT BEFORE MOVING TO THE EAST SUNDAY AND
SUNDAY NIGHT. TEMPERATURES WILL REMAIN ON THE COOLER SIDE FOR FRIDAY
BUT START TO WARM BACK UP AGAIN ON SATURDAY. DURING THE PERIOD AN
UPPER LEVEL RIDGE BUILDS BACK INTO THE WESTERN CONUS.

THE NEXT UPPER LEVEL WAVE AND SURFACE COLD FRONT WILL APPROACH THE
AREA ON TUESDAY. THE MODELS WEAKEN THE UPPER LEVEL WAVE AS IT MOVES
INTO THE PLAINS...BUT WILL KEEP A SLIGHT CHANCE FOR THUNDERSTORMS
FOR MUCH OF THE AREA.

.AVIATION...(FOR THE 06Z KGRI/KEAR TAFS THROUGH 06Z EARLY
THURSDAY MORNING) ISSUED AT 1223 AM CDT WED AUG 26 2015

WHILE VFR CONDITIONS ARE EXPECTED THROUGHOUT MUCH OF THE TAF
PERIOD...A CHANGE IN THE WEATHER PATTERN IS FORECAST WEDNESDAY
NIGHT INTO THURSDAY. FOR THE TAF PERIOD...THE UPPER LEVEL RIDGE
WILL CONTINUE TO DOMINATE THE AREA...WHILE A SURFACE LOW CONTINUES
TO BUILD ALONG THE FRONT RANGE. AS A RESULT SOUTHEASTERLY WINDS
WILL INCREASE WEDNESDAY AFTERNOON WITH GUSTS POSSIBLY APPROACHING
20 KTS AT TIMES. TOWARDS THE END OF THE PERIOD..BY WEDNESDAY
NIGHT AN UPPER LEVEL DISTURBANCE WILL BEGIN TO SWING INTO THE
REGION...GENERATING A LOW LEVEL JET OVERNIGHT. PRECIPITATION
CHANCES WILL INCREASE NORTH OF THE TAF SITES...BUT IT IS POSSIBLE
LOWERED CEILINGS MAY BE NECESSARY WEDNESDAY NIGHT. IN
ADDITION...THE NIGHT TIME INVERSION COMBINED WITH THE LOW LEVEL
JET COULD PRODUCE SOME WEAK LOW LEVEL WIND SHEAR WHICH WILL NEED
TO BE MONITORED.
