AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
609 PM CDT TUE AUG 7 2012

.AVIATION...00Z TAF. WILL KEEP TEMPO MENTION OF THUNDERSTORMS
GOING AT THE TERMINAL FOR FOR A FEW HOURS AS THIS ACTIVITY
ASSOCIATED WITH AN UPPER LEVEL WAVE SHIFTS THROUGH THE REGION.
OTHERWISE...DRY WEATHER WITH VFR CONDITIONS EXPECTED...WITH
VARIABLE WINDS EARLIER ON...BEFORE SWITCHING TO THE NORTHWEST BY
LATE TOMORROW MORNING.

&&

.PREV DISCUSSION... /ISSUED 337 PM CDT TUE AUG 7 2012/

SHORT TERM...TONIGHT THROUGH WEDNESDAY.  FOCUS IS ON CONVECTIVE
POTENTIAL TONIGHT.  THE PATTERN ALOFT FEATURED AN UPPER RIDGE OF
HIGH PRESSURE EXTENDING FROM THE DESERT SOUTHWEST NORTHWARD ACROSS
THE ROCKIES.  ALONG THE EASTERN PERIPHERY OF THE RIDGE...NORTHWEST
FLOW WAS IN PLACE ACROSS THE CENTRAL PLAINS...WITH EMBEDDED
SHORTWAVE TROUGHS TRANSLATING SOUTHEAST THRU THE FLOW.  THIS
ACTIVITY HAS GENERATED SHOWERS AND STORMS TODAY AND AS AN UPSTREAM
WAVE NEAR THE NEB/SD STATE LINE TRANSLATES SOUTHEAST THIS
EVENING...ADDITIONAL CONVECTIVE DEVELOPMENT IS POSSIBLE HEADING INTO
THE EVENING.  SPC MESOANALYSIS INDICATES MLCAPES AROUND 2000 J/KG
AND LIMITED SHEAR...WITH SREF FORECAST PARAMETERS INDICATING SIMILAR
VALUES INTO THE EVENING.  IN THIS ENVIRONMENT...WE MAY
INTERMITTENTLY EXPERIENCE A STRONG TO MARGINALLY SEVERE STORM INTO
THE FIRST PART OF THE EVENING THEN TSTM CHCS DIMINISH HEADING INTO
TONIGHT.

A MORE PRONOUNCED SHORTWAVE TROUGH TRANSLATES SOUTHEAST ALONG THE
MISSOURI RIVER LATE TONIGHT AND WEDNESDAY WITH A FRONTAL BOUNDARY
SWITCHING WINDS NORTHERLY WEDNESDAY. DRIER AIR ADVECTS IN BEHIND
THE BOUNDARY WITH DPS DROPPING INTO THE 40S AND 50S. THE BOUNDARY
REACHES OUR SOUTHAST ZONES BY LATE AFTN WITH 12Z NAM AND 4KM SPC
WRF SUGGESTING AN OUTSIDE CHC FOR CONVECTION IN VCNTY OF BOUNDARY.
CONFIDENCE IN DEVELOPMENT IS NOT HIGH BUT SOMETHING TO KEEP AN EYE
ON.

REGARDING TEMPERATURES...LOW TEMPERATURES TONIGHT WILL AVERAGE IN
THE 60S IN A SIMILAR AIRMASS FROM THE PAST COUPLE OF NIGHTS. THE WARM
AIRMASS REMAINS IN PLACE ON WEDNESDAY WITH H85 TEMPS IN THE UPPER
20S CELSIUS. FORECAST SOUNDINGS INDICATE MIXING WELL ABOVE THIS IN
THE DRY AIRMASS AND EXPECT TEMPS TO CLIMB TO THE 90S FOR HIGHS.

FIRE WEATHER...RELATIVE HUMIDITY VALUES DROP TO THE LOW 20TH
PERCENTILE IN OUR WESTERN ZONES WEDNESDAY AFTERNOON AS DPS LOWER
AND TEMPS RISE...AND WINDS LOOK TO REMAIN JUST BELOW HEADLINE
CRITERIA. FOR NOW WILL JUST MENTION ELEVATED FIRE CONCERN IN HWO.

LONG TERM...WEDNESDAY NIGHT THROUGH TUESDAY.

AS THE UPPER LEVEL RIDGE CONTINUES TO AMPLIFY OVER THE COLORADO
ROCKIES REGION THROUGH THE SHORT TERM...AN UPPER LEVEL TROUGH WILL
CONTINUE TO DEEPEN OVER THE EASTERN HALF OF THE CONUS. THROUGH MUCH
OF THE MID TERM PERIOD...THE PLAINS REMAIN JUST ON THE WESTERN
PERIPHERY OF THE DEEPENING TROUGH AXIS...AND THUS MOST OF THE UPPER
LEVEL SHORT WAVES REMAIN EAST OF THE PLAINS. AT THE SURFACE...A
BROAD AREA OF HIGH PRESSURE WILL SINK ACROSS MUCH OF PLAINS REGIONS
INTO THE GREAT LAKES REGIONS THROUGH FRIDAY...WITH THE SURFACE RIDGE
AXIS SLOWLY SHIFTING EAST. NORTH WINDS CAN BE EXPECTED AHEAD OF THE
SURFACE RIDGE...BEFORE TURNING EASTWARD AS THE SURFACE HIGH SINKS
ACROSS THE UPPER MISSISSIPPI RIVER VALLEY. COOLER AIR WILL SLIDE
SOUTH WITH THE SURFACE HIGH...SLIDING ACROSS THE PLAINS FROM THE
EAST. WITH COOLER 850 TEMPERATURES RANGING IN THE MID TO UPPER
TEENS...HIGH TEMPERATURES ROUGHLY 5 DEGREES BELOW NORMAL CAN BE
EXPECTED. THUS...WENT WITH LOW TO MID 80S ACROSS MUCH OF THE CWA
WITH A FEW UPPER 80S ACROSS NORTH CENTRAL KANSAS BOTH THURSDAY AND FRIDAY.
WITH THE PLAINS SITUATED BETWEEN THE UPPER LEVEL SYSTEMS...A DRY
FORECAST IS EXPECTED THROUGHOUT THE MID TERM.

LOOKING TOWARDS THE LONG TERM PERIOD...THE UPPER LEVEL TROUGH WILL
SLOWLY DRIFT ACROSS THE OHIO RIVER VALLEY WHILE THE RIDGE BREAKS
DOWN ACROSS THE SOUTHWEST. A FEW UPPER LEVEL PERTURBATIONS WILL
LIKELY SLIDE THROUGH THE DAKOTAS DURING THE LONG TERM...WITH
POSSIBLE CHANCES FOR PRECIPITATION EXPECTED. BEGINNING SATURDAY
NIGHT...ONE SUCH WAVE WILL SLIDE ACROSS SOUTH DAKOTA...WHILE A
SURFACE LOW DEVELOPS OVER THE FRONT RANGE. MODELS REMAIN INCONSISTENT
THROUGHOUT THE LONG TERM ON PLACEMENT AND TIMING OF POPS...BUT AT
LEAST EXPECT SOME CHANCE FOR POPS IN THE PERIOD. DECIDED TO CONTINUE
WITH ALLBLEND POPS LEAVING SLIGHT TO CHANCE MENTION IN FRIDAY NIGHT
THROUGH SATURDAY...AS THE UPPER LEVEL WAVE AND DECENT POSITIVE
VORTICITY ADVECTION PER THE GFS SOLUTION SLIDES EASTWARD ACROSS THE PLAINS.

TOWARDS THE END OF THE PERIOD...A SECONDARY UPPER LEVEL TROUGH WILL
BEGIN TO DEEPEN ALONG THE WESTERN COAST...THUS SHIFTING THE UPPER
LEVEL RIDGE EASTWARD. ALTHOUGH MODELS TRY TO INDICATE SOME RIDGING
OVER THE PLAINS...NUMEROUS SHORT WAVES WILL LIKELY RIDE ALONG THE
UPPER PERIPHERY...COMBINED WITH SURFACE LOWS ALONG THE FRONT
RANGE...LIKELY GENERATING SOME CHANCES FOR POPS BY MIDWEEK. WHILE
DECIDED TO CONTINUE WITH ALL BLEND POPS IN THE PERIOD...CONFIDENCE
IS NOT HIGH REGARDING TIMING AND LOCATION OF POPS. AS THE GFS
SOLUTION SUGGESTS A MORE DAY TIME EVENT...WHILE THE ECMWF SUGGESTS A
MORE MONDAY NIGHT SOLUTION.

AS FOR TEMPERATURES IN THE LONG TERM...FAIRLY NORMAL TEMPERATURES
RETURN TO THE FORECAST AREA WITH ROUGHLY UPPER 80S TO LOWER 90S
EXPECTED.
