Area forecast discussion, Jul 10, 5:43 PM MDT, 40 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
543 PM MDT WED JUL 10 2013

.UPDATE...
ISSUED AT 542 PM MDT WED JUL 10 2013

THUNDERSTORMS SO FAR HAVE NOT BEEN AS WIDESPREAD OR INTENSE AS
EXPECTED AS OF 2315Z. STRONGEST STORMS WERE LOCATED OVER FAR
NORTHERN GOSHEN AND WEST CENTRAL SIOUX COUNTIES. POTENTIAL STILL
EXISTS FOR ADDITIONAL STRONG STORMS OVER THE PANHANDLE AND NEARBY
PARTS OF WYOMING THROUGH THE EVENING...WITH THE MOIST AND UNSTABLE
ATMOSPHERE. IN A RECENT UPDATE HAVE INCREASED POPS OVER THE
NORTHERN PANHANDLE FOR THE EVENING AND ADJUSTED POPS ELSEWHERE.

&&

.SHORT TERM...(THIS EVENING THROUGH FRIDAY NIGHT)
ISSUED AT 158 PM MDT WED JUL 10 2013

A FEW SHOWERS AND STORMS ONGOING OVER AND JUST EAST OF THE LARAMIE
RANGE EARLY THIS AFTERNOON. EXPECT THIS TO GRADUALLY INCREASE
THROUGH LATE THIS AFTERNOON AS IT MOVES EAST AND SOUTHEAST. EXPECT
THE ACTIVITY TO CLEAR THE CWA EARLY THIS EVENING. A FEW STORMS
COULD BE SEVERE WITH GOOD SHEAR AND INSTABILITY IN
PLACE...ESPECIALLY OVER THE SOUTHERN PANHANDLE.

DRIER AND VERY WARM/HOT CONDITIONS EXPECTED THURSDAY AS AN UPPER
RIDGE MOVES ACROSS THE REGION WITH TEMPERATURES LIKELY TOPPING
OUT AROUND 100 OVER PARTS OF THE PANHANDLE. ISOLATED CONVECTION
NOT OUT OF THE QUESTION OVER THE PLAINS BUT WILL MAINTAIN SILENT
POPS FOR NOW. THE UPPER RIDGE WILL SIFT EAST AND TILT SW-NE
THURSDAY NIGHT AND FRIDAY LEAVING A MORE SWLY FLOW ALOFT OVER THE
AREA. THIS WILL ADVECT SOME INCREASED MOISTURE BACK ACROSS THE CWA
AND WITH ANY RIPPLES IN THE FLOW SHOULD SEE SOME INCREASE IN
MAINLY LATE DAY CONVECTION FRIDAY INTO FRIDAY EVENING.
TEMPERATURES A BIT COOLER FRIDAY DUE TO LOWER 700MB TEMPS BUT
STILL VERY WARM OVERALL.

.LONG TERM...(SATURDAY THROUGH WEDNESDAY)
ISSUED AT 300 PM MDT WED JUL 10 2013

ALL MODELS SHOW THE STRONG UPPER LEVEL HIGH REMAINING OVER THE
CENTRAL GREAT PLAINS THROUGH THE WEEKEND...AND LIKELY BUILDING
NORTH AS WELL. THIS GENERAL PATTERN WILL ALLOW SUBTROPICAL
MOISTURE TO MOVE NORTHWARD OVER THE ROCKYS AND REMAIN OVER THE
AREA POSSIBLY INTO EARLY NEXT WEEK AS THE RIDGE FLATTENS A BIT.
LLVL INSTABILITY AND HIGH PW/S OVER 1.00 INCH TO 1.50 INCHES WILL
RESULT IN AFTERNOON/EVENING SHOWERS AND THUNDERSTORMS OVER MOST OF
THE AREA BOTH SATURDAY AND SUNDAY. THUNDERSTORMS WILL DEVELOP OVER
SOUTHEAST WYOMING EARLIER IN THE AFTERNOON AND THEN MOVE EASTWARD
INTO WESTERN NEBRASKA LATER IN THE AFTERNOON OR IN THE EVENING. A
FEW STRONG TSTORMS ARE POSSIBLE EAST OF THE LARAMIE RANGE...BUT
0-6KM SHEAR APPEARS TO BE MINIMAL ON SATURDAY...AND MAYBE MODERATE
ON SUNDAY. THE GEM AND ECMWF APPEAR TO BE MORE
AGGRESSIVE...SHOWING THE POSSIBILITY OF HEAVY RAIN WITH VERY SLOW
STORM MOTION THIS WEEKEND. INCREASED POP BETWEEN 30 TO 60 PERCENT
ACROSS THE AREA...HIGHEST OVER THE MOUNTAINS.

FOR NEXT WEEK...THE GFS SHOWS THE UPPER LEVEL HIGH RETROGRADING
WESTWARD WHICH WILL RESULT IN HIGHER SUBSIDENCE ALOFT OVER THE
EASTERN PLAINS. THIS MAY ENOUGH TO LIMIT TSTORM DEVELOPMENT EAST
OF I25...WITH SHOWERS AND TSTORMS CONTINUING OVER THE HIGHER
TERRAIN OF SOUTHEAST WYOMING. ECMWF STILL SHOWS THIS HIGH FURTHER
EAST WITH TSTORM ACTIVITY MORE WIDESPREAD ACROSS THE FORECAST
AREA. KEPT POP BETWEEN 10 TO 20 PERCENT FOR NOW EAST OF THE
LARAMIE RANGE DUE TO UNCERTAINTY WITH THE POSITION OF THE UPPER
LEVEL HIGH. MAX AND MIN TEMPERATURES WILL REMAIN WELL ABOVE NORMAL
THROUGH THE WHOLE FORECAST PERIOD...WITH HIGHS IN THE MID TO UPPER
80S WEST OF THE LARAMIE RANGE...AND 90S ELSEWHERE.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY AFTERNOON)
ISSUED AT 542 PM MDT WED JUL 10 2013

VFR CONDITIONS WILL CONTINUE OVER THE CWA THROUGH FRIDAY. PATCHY
LOW CLOUDS AND FOG MAY BE POSSIBLE ALONG AND JUST EAST OF THE
SOUTHERN LARAMIE RANGE BETWEEN 08Z AND 15Z. SOME THUNDERSTORMS
WILL CONTINUE OVER THE EAST PART OF THE CWA THROUGH 05Z. THEN
AFTER A DRIER DAY THURSDAY...MORE LATE DAY STORMS CAN BE EXPECTED
FOR FRIDAY. BRIEF MVFR CEILINGS AND VISIBILITIES IN RAIN WILL BE
POSSIBLE WITH THE ACTIVITY.

&&

.FIRE WEATHER...
ISSUED AT 158 PM MDT WED JUL 10 2013

NO CONCERNS EXPECTED AS WEATHER ELEMENTS ARE EXPECTED TO REMAIN
NON-CRITICAL OTHER THAN SOME LOW AFTERNOON RELATIVE HUMIDITIES
OVER PARTS OF SOUTHEAST WYOMING ON THURSDAY. WIDELY SCATTERED
SHOWERS AND THUNDERSTORMS WILL OCCUR INTO THIS EVENING MAINLY OVER
SOUTHEAST PARTS OF THE CWA...WITH MORE WIDESPREAD ACTIVITY IN THE
AFTERNOONS AND EVENINGS FRIDAY INTO EARLY NEXT WEEK AS SOME
MONSOONAL-TYPE MOISTURE MOVES ACROSS THE REGION.
