332 AM MDT SAT JUN 18 2011

.SHORT TERM...TODAY THROUGH MONDAY NIGHT...
SW FLOW WILL OCCUR ALOFT AS AN UPPER TROUGH BEGINS TO DEEPEN OVER
THE WESTERN U.S. A DISTURBANCE IN THE FLOW WILL MOVE ACROSS THE
EASTERN HALF OF THE CWA TODAY. LI/S IN THE NEB PANHANDLE WILL BE
-3 TO -4 IN THE NEBRASKA PANHANDLE BY LATE THIS AFTERNOON WITH
CAPE VALUES OF 1000 TO 1500 J/KG. LI/S IN THE WY PORTION OF THE CWA
WILL BE FROM 0 TO -2 WITH CAPES OF 400-500 J/KG. AGREE WITH SPC
THAT SEVERE STORMS WILL BE LIKELY IN THE NEBRASKA PANHANDLE THIS
AFTERNOON AND EVENING WITH THE MAIN THREAT BEING LARGE HAIL AND
GUSTY WINDS. BRIEF HEAVY RAIN WILL ALSO OCCUR WITH THE STRONGER
STORMS. THUNDERSTORMS WILL ALSO OCCUR ACROSS THE REST OF THE CWA
WITH SMALL HAIL...BRIEF HEAVY RAIN AND GUSTY WINDS WITH THE
STRONGER STORMS.  SW FLOW WILL CONT ALOFT TONIGHT AS THE UPPER
TROUGH CONTS TO DEEPEN OVER THE WESTERN U.S. ON SUN...SW FLOW WILL
CONT AS THE UPPER TROUGH AXIS BEGINS TO MOVE INTO WESTERN WY. THE
ASSOCIATED COLD FRONT WILL BEGIN TO MOVE INTO THE CWA LATE SAT
NIGHT AND WILL BE THROUGH THE AREA BY SUN AFTERNOON. LI/S ON SUN
WILL BE FROM -3 TO -5 IN THE SOUTHERN PH AHEAD OF THE FRONT...AND
FROM 0 TO -3 IN THE WY PORTION OF THE CWA. CAPES WILL BE FROM 1000
TO 1800 IN THE NEB PH SUN AFTERNOON...SO SEVERE STORMS WILL AGAIN
BE LIKELY IN THIS AREA SUN AFTERNOON AND EVENING. THUNDERSTORMS
WILL OCCUR ACROSS THE REST OF THE CWA WITH SMALL HAIL AND BRIEF
HEAVY RAIN LIKELY. THE UPPER TROUGH WILL CONTINUE TO DEEPEN AS
THE AXIS MOVES TO CENTRAL WY SUN NIGHT. ON MON...THE UPPER TROUGH
AXIS WILL MOVE EAST OF THE CWA WITH A DISTURBANCE MOVING ACROSS
THE FORECAST AREA AS IT ROTATES AROUND THE UPPER LOW OVER THE
CENTRAL PLAINS. THIS WILL RESULT IN A CHANCE OF SHOWERS AND
AFTERNOON AND EVENING THUNDERSTORMS FOR THE CWA. FOR MON
NIGHT...CYCLONIC NORTH FLOW WILL BE OVER THE AREA WITH A CLOSED
UPPER LOW DEVELOPING OVER THE CENTRAL PLAINS. HIGH TEMPERATURES
WILL BE FROM 3 TO 5 DEGREES BELOW NORMAL TODAY AND SUNDAY...AND
FROM 10 TO 12 DEGREES BELOW NORMAL ON MONDAY.

.LONG TERM...TUESDAY THROUGH SATURDAY...
00Z MEDIUM RANGE GLOBAL MODELS ARE CONSISTENT IN CARRYING THE
INCREASINGLY VERTICALLY STACKED LOW PRESSURE SYSTEM INTO ERN
NEBRASKA/WRN IOWA DURING THE DAY ON TUESDAY. THE RESULTANT IMPACT
WILL BE FOR GRADUALLY DRYING CONDITIONS FROM WEST TO EAST DURING THE
DAY AS UPPER-LEVEL RIDGING WORKS IN. THE POSITIVELY TILTED RIDGE
AXIS WILL SLOWLY BUILD OVER THE CWA ON WEDNESDAY AND WEDNESDAY
NIGHT. AT THE SFC...THE CORRESPONDING NRN HIGH PLAINS HIGH PRESSURE
WILL BUILD SOUTH WITH TIME ON WEDNESDAY. SO FOR AREAS EAST OF THE
LARAMIE RANGE...BOUNDARY LAYER FLOW WILL TURN FROM NORTHEASTERLY
EARLY IN THE DAY TO SOUTHEASTERLY LATE IN THE DAY. OPTED TO INCLUDE
SOME SHOWER/THUNDERSTORM CHANCES FOR THE HIGHER TERRAIN WEDNESDAY
AFTERNOON/EARLY EVENING AS UPSLOPE FLOW SHOULD BE ABLE TO INITIATE
AT LEAST SOME WEAK CONVECTION. IF CONVECTION IS ABLE TO DEVELOP...
WOULD EXPECT IT TO REMAIN WEAK AS SBCAPES OF 200 TO 400 J/KG WILL BE
ABOUT IT. BOUNDARY LAYER RETURN FLOW WILL STRENGTHEN FURTHER ON
THURSDAY...SO BETTER MOISTURE AND INSTABILITY WILL BE AVAILABLE FOR
AREAS EAST OF THE LARAMIE RANGE. PROGD SOUNDINGS SHOW AREAS OVER THE
WRN NEBRASKA WILL BE CAPPED ON THURSDAY...SO CONFINED CONVECTION
CHANCES TO SOUTHEAST WYOMING...WITH BEST CHANCES ALONG AND EAST OF
THE LARAMIE RANGE. UPPER RIDGE AXIS DRIFTS INTO THE PLAINS ON FRIDAY
AS ANOTHER UPPER LOW TAKES SHAPE OVER THE PAC NW/SW CANADA. THE 00Z
GFS IS A BIT MORE AMPLIFIED THAN THE 00Z ECMWF...BUT IN GENERAL
AGREEMENT WITH ITS PLACEMENT. BOTH MODELS KICK OUT A SHORTWAVE AS
FLOW BECOMES SOUTHWEST AROUND THE UPSTREAM UPPER LOW ON BOTH FRIDAY
AND SATURDAY. INSTABILITIES WILL CONTINUE TO INCREASE AS RETURN FLOW
CONTINUES TO ADVECT BETTER BOUNDARY LAYER MOISTURE NORTH ALONG THE
FRONT RANGE. EVEN THOUGH PROBABLY ON THE HIGH SIDE...THE 00Z GFS
DEPICTS CAPE VALUES IN EXCESS OF 2000 J/KG OVER THE WRN NEBRASKA
PANHANDLE ON BOTH FRIDAY AND SATURDAY AFTERNOON. SO...WOULD EXPECT
THESE TWO DAYS TO PROVIDE THE NEXT CHANCE FOR SEVERE WEATHER FOR THE
EASTERN PLAINS. AFTER A COOLER DAY ON TUESDAY...H7 TEMPERATURES WILL
CLIMB TO AROUND 10C BY WEDNESDAY AND 15C FOR THURSDAY THROUGH
SATURDAY. SO AFTERNOON HIGHS IN THE 60S ON TUESDAY WILL CLIMB INTO
THE 70S FOR WEDNESDAY...AND INTO THE 80S FOR THURSDAY THROUGH
SATURDAY.

&&

.AVIATION...12Z TAF ISSUANCE...
AFTER A QUIET VFR MORNING...EXPECT CLOUDS TO THICKEN AS SHOWERS
AND THUNDERSTORMS DEVELOP BY THIS AFTERNOON AND EVENING. THE BEST
CHANCE TO SEE THESE THUNDERSTORMS WILL BE AT AIRFIELDS EAST OF THE
LARAMIE RANGE. IN FACT...A FEW OF THESE THUNDERSTORMS MAY BECOME
STRONG TO SEVERE CONTAINING HAIL AND DAMAGING WINDS ACROSS
NEBRASKA AIRPORTS. CIGS/VSBYS MAY BE REDUCED BRIEFLY WITHIN THESE
THUNDERSTORMS TO THE MVFR CATEGORY. HOWEVER...WITH LIMITED
CONFIDENCE ON CONVECTIVE TIMING AND COVERAGE...WILL KEEP TAF SITES
IN VFR WITH VCTS...UNTIL SPECIFICS BECOME CLEARER.

&&

.FIRE WEATHER...
NO FIRE WEATHER CONCERNS AT THIS TIME DUE TO FIRE DANGER IN THE
LOW CATEGORY AND EXPECTED WETTING RAIN ACROSS THE DISTRICT THROUGH
SUNDAY NIGHT.

&&

.HYDROLOGY...
RAINFALL FROM A QUARTER INCH TO LOCALLY OVER AN INCH IS PREDICTED
FOR THE CWA TODAY THROUGH MONDAY...WHICH MAY FURTHER AGGRAVATE THE
ONGOING FLOODING CONCERNS. FLOOD WARNINGS REMAIN IN EFFECT FOR THE
UPPER NORTH PLATTE RIVER DUE TO SNOW MELT AND RUNOFF FROM THE SIERRA
MADRE AND SNOWY RANGES. THE RATE OF SNOW MELT WILL DECREASE SLIGHTLY
TODAY THROUGH TUESDAY AS MOUNTAIN TEMPERATURES WILL BE COOLER.
