Severe Thunderstorm Warning 124, NWS Hastings, NE

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
600 PM CDT SUN JUL 15 2007

.AVIATION...00Z TAF ISSUANCE...THUNDERSTORMS IN CENTRAL NEBRASKA
WILL CONTINUE TO DRIFT SOUTHEAST. EXPECT THEM TO BE IN THE KGRI
AREA AROUND 02Z. THESE STORMS WILL PRODUCE SOME BRIEF HEAVY RAIN
AND SOME GUSTY NORTHWEST WINDS. WINDS AT KODX GUST TO 35 KTS AT
00Z SO HAVE INCLUDED SOME GUSTS TO AROUND 40 KTS AT KGRI. STORMS
SHOULD BE PAST AROUND 04Z WITH VFR CONDITIONS TO FOLLOW. EXPECT A
SURFACE BOUNDARY TO PASS THROUGH THE AREA IN THE MORNING AND TURN
THE WINDS TO THE NORTH.  KISNER

.PREV DISCUSSION... /ISSUED 213 PM CDT SUN JUL 15 2007/

SHORT TERM...TONIGHT THROUGH 12Z TUESDAY. CONCERN FOR THIS PERIOD
IS IF STORMS ARE GOING TO FIRE THIS AFTERNOON AND EVENING. UPPER
WAVE COMING DOWN FROM SD WILL HAVE FAIRLY GOOD ATMOSPHERE TO WORK
WITH. MLCAPES ARE 3000+ AND CIN IS NEAR ZERO. SURFACE TEMPS GETTING
NEAR CONVECTIVE TEMPS...SO NEXT FEW HOURS WILL BE INTERESTING TO SEE
WHERE THE CU FIELD SETS UP AND HOW THINGS PROGRESS. HAVE INCLUDED
ALL OF NEBR ZONES WITH A CHANCE/SLGT CHANCE FOR STORMS THIS EVENING
WITH BEST CHANCES IN NORTHERN AREAS. AGREE WITH NEIGHBORING
OFFICES THAT THERE WILL BE A CHANCE FOR SOME STORMS MAKING IT INTO
NORTHERN KANSAS AND HAVE EXPANDED SLIGHT CHANCES INTO KS ZONES. ONCE
WE LOOSE MAX HEATING...EXPECT MOST ACTIVITY TO DROP OFF QUICKLY.

NEXT QUESTION IS IF WE GET THE SURFACE FRONT TO MOVE INTO THE AREA
AS PROGGED BY THE NAM MODEL. THIS WOULD TURN OUR WINDS TO THE EAST
AND CUT AFTERNOON HEATING OFF. THE GFS HOLDS THE FRONT TO THE NORTH
WHICH WILL ALLOW FOR FULL HEATING.  GIVEN THAT WE ARE IN NORTHWEST
FLOW AND THESE WAVES CONTINUE TO COME OVER THE TOP OF THE RIDGE...
CAN SEE THE FRONT MAKING IT INTO THE AREA AND WILL FORECAST
WINDS/TEMPS ACCORDINGLY.

LONG TERM...12Z TUESDAY THROUGH SUNDAY. FORECAST CONCERNS INCLUDE A
COUPLE DIFFERENT CHANCES FOR THUNDERSTORMS...AND POSSIBLE COOL DOWN
WITH FRONTAL PASSAGE LATER IN THE WEEK.

THE OVERALL PATTERN DURING THE EXTENDED PERIOD ISN/T LOOKING QUITE
AS BENIGN AS IT WAS 24 HOURS AGO. NORTHWEST FLOW ALOFT PREVAILS OVER
THE REGION AT THE BEGINNING OF THE PERIOD WITH THE UPPER RIDGE AXIS
STILL TO THE WEST OVER THE ROCKIES. THE LAST COUPLE RUNS OF THE NAM
AND GFS HAVE INDICATED AN EMBEDDED SHORTWAVE SLIDING ACROSS ON
TUESDAY...SO DECIDED TO INSERT SOME SLIGHT CHANCE POPS TO ACCOUNT
FOR THIS. ALSO COOLED TEMPS SOME GIVEN EXPECTED CLOUDS AND POSSIBLE
PRECIP WITH THE WAVE...ALONG WITH A SOUTHEAST SURFACE WIND WHICH
ISN/T REAL CONDUCIVE FOR GREAT WARMING. THE UPPER RIDGE AXIS TRIES
TO SHIFT EASTWARD OVER THE PLAINS DURING THE MID TO LATE WEEK
PERIOD...BUT MODELS DIFFER ON THIS SCENARIO WITH SOME SHIFTING IT
EAST AND OTHERS HOLDING IT BACK OVER THE ROCKIES THEREBY KEEPING US
IN A MORE ACTIVE NORTHWEST FLOW REGIME WITH OCCASIONAL SHORTWAVES
DROPPING THROUGH. NEVERTHELESS...THE NEXT BEST OPPORTUNITY FOR
THUNDERSTORMS LOOKS TO COME THURSDAY NIGHT. MODELS HAVE COME INTO
MUCH BETTER AGREEMENT IN BRINGING A BACKDOOR COLD FRONT INTO THE AREA
THURSDAY NIGHT AS AN UPPER WAVE SWINGS THROUGH THE GREAT LAKES. HAVE
INSERTED PRECIP CHANCES THURSDAY NIGHT WITH THE FRONT MOVING
THROUGH...AND COOLED TEMPS FRIDAY INTO THE WEEKEND BEHIND THE FRONT.
PRECIP CHANCES FRIDAY AND BEYOND DEPEND ON HOW FAR SOUTH THE FRONT
PUSHES...WHICH IS A GOOD QUESTION AT THIS POINT. CURRENT INDICATIONS
ARE THAT IT WILL PUSH FAR ENOUGH SOUTH TO SHOVE PRECIP SOUTH OF THE
FORECAST AREA SO HAVE GONE DRY FRIDAY AND BEYOND...BUT IF IT ENDS UP
STALLING FURTHER NORTH...POPS MAY EVENTUALLY NEED TO BE EXTENDED
BEYOND THURSDAY NIGHT.

GID WATCHES/WARNINGS/ADVISORIES...
NE...NONE.
KS...NONE.
