.AVIATION...00Z TAF ISSUANCE
LATEST RADAR LOOP WAS SHOWING SHOWING THE SHOWERS AND
THUNDERSTORMS GRADUALLY DIMINISHING ACROSS AREAS ALONG AND WEST OF
THE LARAMIE RANGE. MEANWHILE...EAST OF THE LARAMIE RANGE...CLUSTERS
OF THUNDERSTORMS CONTINUE TO DEVELOP WHICH IS PRODUCING GUSTY
WINDS BETWEEN 40 AND 50 MPH. THE THUNDERSTORM OUTFLOW BOUNDARY
SHOULD CONTINUE TO PUSH EAST THROUGH BANNER AND KIMBALL COUNTY
DURING THE NEXT HOUR OR SO. IT WILL BE INTERESTING TO SEE HOW FAR
EAST THIS BOUNDARY PROPAGATES THIS EVENING. IF IT DOES CONTINUE TO
PUSH EAST IT MAY TRIGGER A FEW ISOLATED SHOWERS AND STORMS AS IT
ENCOUNTERS POCKETS OF INSTABILITY. FURTHER NORTH...THE INSTABILITY IS A
LITTLE BETTER ALONG WITH MORE 0-6KM SHEAR. THIS AREA MAY SEE SOME
STRONGER STORMS. THE CHADRON TAF SITE WILL CERTAINLY NEED TO BE
WATCHED AS THE STORM ACROSS SIOUX COUNTY PUSHES EAST-NORTHEAST.

OTHERWISE...THE CONVECTION SHOULD BEGIN TO DIE AFTER SUNSET...WITH
MORE SCATTERED SHOWERS AND THUNDERSTORMS DEVELOPING TOMORROW
AFTERNOON.

UPDATE...
WE HAVE SENT A QUICK UPDATE TO RAISE THE PRECIPITATION CHANCES
THIS EVENING. LATEST RADAR LOOP WAS SHOWING SCATTERED TO NUMEROUS
SHOWERS AND THUNDERSTORMS CONTINUING TO DEVELOP OVER AREAS ALONG
AND WEST OF THE LARAMIE RANGE. THIS CLUSTER OF SHOWERS AND STORMS
WILL PERSIST THROUGH THE EARLY EVENING BEFORE DIMINISHING. FREQUENT
LIGHTNING WILL BE THE ONE OF THE COMMON THEMES FROM THESE STORMS
WHICH MAY START FIRES. IN ADDITION...THE STORMS WILL PRODUCE GUSTY
ERRATIC WINDS WHICH MAY CAUSE ANY FIRE STARTS TO SPREAD QUICKLY.

PREV DISCUSSION... /ISSUED 315 PM MDT SAT JUL 21 2012/

SHORT TERM...TONIGHT THROUGH MONDAY NIGHT...CURRENT KCYS RADAR
LOOP SHOWS SHOWERS AND TSTORMS DEVELOPING OVER THE HIGHER TERRAIN
OF THE LARAMIE RANGE AND SNOWY RANGE THIS AFTERNOON. OBSERVATIONS
SHOW A WEAK COOL FRONT LOCATED ALONG THE NORTHERN LARAMIE RANGE
FROM JUST NORTH OF DOUGLAS EASTWARD TO SOUTH OF ALLIANCE
NEBRASKA. THIS FRONT IS SLOWLY DRIFTING NORTHWARD THIS AFTERNOON
AND MAY BECOME THE FOCUS OF STRONGER THUNDERSTORMS THIS EVENING.
HOWEVER...MOISTURE IS LIMITED SINCE MOST OF THE DEEPER MOISTURE IS
FURTHER WEST ASSOCIATED WITH THE MONSOON FLOW AROUND THE STRONG
UPPER LEVEL HIGH TO OUR SOUTHEAST. CAN NOT RULE OUT A FEW STRONGER
TSTORMS ACROSS FAR EASTERN WYOMING AND NORTHWEST NEBRASKA
PANHANDLE THROUGH LATE THIS EVENING. THE PRIMARY THREAT FROM
TSTORMS WILL BE HEAVY RAINFALL AND STRONG GUSTY WINDS. ISOLATED
TO WIDELY SCATTERED TSTORMS ARE EXPECTED OUTSIDE OF THIS AREA AS
WELL...BUT THEY SHOULD REMAIN RATHER WEAK WITH MAINLY LOCALLY
HEAVY RAINFALL AND OCCASIONAL LIGHTNING.

HIGH PRESSURE ALOFT WILL REMAIN SOUTHEAST OF THE REGION THROUGH
SUNDAY AND MONDAY...SO DO NOT EXPECT MUCH CHANGE TO THE CURRENT
WEATHER PATTERN INTO EARLY NEXT WEEK. AFTERNOON AND EVENING
SHOWERS AND TSTORMS WILL CONTINUE EACH DAY WITH WARMER THAN NORMAL
TEMPERATURES. HOWEVER...THERE WILL BE A GREATER CHANCE OF
WIDESPREAD RAINFALL ACROSS THE FORECAST AREA COMPARED TO TODAY AS
THE HIGH SHIFTS EASTWARD...ALLOWING MORE SUBTROPICAL MOISTURE TO
MOVE INTO THE EASTERN PORTION OF THE FORECAST AREA. INCREASED POP
AROUND 60 TO 70 PERCENT OVER THE MOUNTAINS...WITH POP BETWEEN 30
TO 50 PERCENT FOR THE LOWER ELEVATIONS INCLUDING THE HIGH VALLEYS
WEST OF THE LARAMIE RANGE. SOME LOCATIONS MAY RECEIVE BETWEEN A
QUARTER TO HALF INCH OF RAINFALL FROM THESE STORMS ALONG WITH
GUSTY WINDS. HIGH TEMPERATURES WILL REMAIN IN THE UPPER 80S TO
MIDDLE 90S OVER SOUTHEAST WYOMING WITH HIGHS BETWEEN 95 TO 105
OVER WESTERN NEBRASKA.

LONG TERM...TUESDAY THROUGH FRIDAY NIGHT...
UPPER LEVEL RIDGE WILL TO FLATTEN TUESDAY AND WEDNESDAY AS THE
CENTER OF THE UPPER LEVEL HIGH SHIFTS INTO THE SOUTHEAST CONUS. THE
FLATTENING RIDGE WILL ALLOW A WEAK COLD FRONT TO SHIFT ACROSS THE
AREA LATE TUESDAY AND TUESDAY NIGHT...BRINGING DRYER AND SLIGHTLY
COOLER AIR INTO THE FORECAST AREA. HIGH TEMPERATURES SHOULD BE
SEVERAL DEGREES COOLER ACROSS THE NEBRASKA PANHANDLE BY WEDNESDAY
BUT HIGH WILL STILL BE IN THE LOWER TO MID 90S.

DRYER AIR WILL DECREASE THE CHANCES FOR THUNDERSTORMS THROUGH MUCH
OF THE EXTENDED FORECAST PERIOD. BEST CHANCE FOR THUNDERSTORMS WILL
BE TUESDAY AS THE COLD FRONT INTERACTS WILL MONSOONAL MOISTURE.
STILL A FEW DAYS OUT...BUT BASED ON SLOW MOVING UPPER LEVEL FLOW AND
PRECIPITABLE WATER ABOVE 1 INCH HEAVY RAIN MAY BE A CONCERN TUESDAY
AFTERNOON EAST OF THE LARAMIE RANGE. CHANCES FOR THUNDERSTORMS WILL
LINGER WEDNESDAY AFTERNOON ACROSS THE PANHANDLE AS AN UPPER LEVEL
JET STREAK PROVIDES LIFT...BUT MOISTURE WILL BE LIMITED TO KEEP ANY
THUNDERSTORM ACTIVITY ISOLATED.

UPPER LEVEL RIDGE WILL AGAIN BEGIN TO BUILD ACROSS THE WESTERN CONUS
LATE THIS WEEK AND INTO THE WEEKEND. GFS AND ECMWF IN RELATIVE GOOD
AGREEMENT ALTHOUGH THE ECMWF DOES KEEP THE RIDGE AXIS SLIGHTLY
FARTHER WEST. GFS ENSEMBLE RUNS WERE CLOSELY CLUSTERED GIVEN 5 TO 7
DAYS IN THE FUTURE. RIDGE WILL ALLOW TEMPERATURES TO ONCE AGAIN PUSH
WELL ABOVE NORMAL WITH HIGHS FROM THE UPPER 80S AND 90S WEST AND
90S TO AROUND 100 EAST. CHANCES FOR PRECIPITATION WILL BEGIN TO
INCREASE BY LATE IN THE WEEK AS MONSOONAL MOISTURE RETURNS ON THE
BACKSIDE OF THE RIDGE.

AVIATION...18Z TAF ISSUANCE...
MAINLY VFR ACROSS THE FORECAST AREA THROUGH THE PERIOD WITH THE
EXCEPTION OF THUNDERSTORM ACTIVITY. SCATTERED AFTERNOON
THUNDERSTORMS OVER HIGHER ELEVATIONS OF WYOMING THIS AFTERNOON
WITH ISOLATED THUNDERSTORMS INTO LOWER ELEVATIONS. ISOLATED
THUNDERSTORMS EXPECTED IN THE NEBRASKA PANHANDLE LATE AFTERNOON
AND EVENING. GUSTY WINDS WILL ACCOMPANY THESE THUNDERSTORMS WITH
WIND GUSTS OF UP TO 50 MPH POSSIBLE. THUNDERSTORMS WILL WEAKEN
SHORTLY AFTER SUNSET...WITH JUST SOME MID/UPPER LEVEL CLOUDS AND A
FEW SHOWERS PERSISTING OVERNIGHT.

FIRE WEATHER...FIRE WEATHER CONCERNS WILL REMAIN LOW THROUGH NEXT
WEEK AS A PERSISTENT WEATHER PATTERN CONTINUES OVER THE AREA.
STRONG HIGH PRESSURE WILL REMAIN OVER THE CENTRAL ROCKIES/CENTRAL
PLAINS...ALLOWING SUBTROPICAL MOISTURE TO PUSH NORTHWARD ACROSS
THE AREA. EXPECT A DAILY THREAT OF THUNDERSTORMS THROUGH AT LEAST
WEDNESDAY WITH WETTING RAINS POSSIBLE. THE BEST CHANCE FOR WETTING
RAINFALL WILL LIKELY BE SUNDAY AND MONDAY EVENING.
