AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
417 AM MDT SAT JUL 28 2007

.SHORT TERM...TODAY THROUGH SUNDAY NIGHT...
ANOTHER DAMP DAY IN STORE FOR AREAS ALONG AND EAST OF THE LARAMIE
RANGE TODAY. AREA RAOBS AT 00Z CONTINUE TO INDICATE PWATS OF
AROUND AN INCH WHICH IS ROUGHLY 150 TO 200 PERCENT ABOVE SEASONAL
NORMALS. IN THE MID/UPPER LEVELS...A H5 SHORTWAVE EXTENDED FROM
THE NORTHEAST TO SOUTHWEST CORNER OF WYOMING EARLY THIS MORNING.
THIS FEATURE WAS INTERACTING WITH THE VERY MOIST AIR MASS IN PLACE
TO PRODUCE ONGOING CONVECTION ACROSS THE SOUTHERN NEBRASKA
PANHANDLE. 00Z MODELS HAD QPF FIELDS TOO FAR NORTH INTO ERN ZONES
OF THE CWA. CURRENT SATELLITE TRENDS DEPICT THE LARGE AREA OF
CONVECTIVE PRECIPITATION EXTENDING FROM CHEYENNE COUNTY AND
SOUTHEAST. EVEN THOUGH THE QPF FIELDS WERE DEPICTED POORLY...STILL
HAVE THE RIGHT IDEA IN MOVING THE MCS SLOWLY EAST AND SOUTHEAST
WITH TIME. SO EXPECT RATHER LIMITED CONVECTIVE COVERAGE THIS
MORNING WITH THE EXCEPTION OF THE SOUTHERN NEBRASKA PANHANDLE. LOW
CLOUDS ALSO HANGING IN ACROSS THE CWA. THESE WILL DESCEND INTO
PATCHY FOG THIS MORNING. LOW CLOUDS AND FOG WILL BURN OFF BY MID
MORNING GIVING WAY TO MORE SUNSHINE THIS PM. SOLAR INSOLATION WILL
DESTABILIZE THE ATMOSPHERE ONCE AGAIN THIS AFTERNOON PROVIDING
ANOTHER ROUND OF AFTERNOON AND EVENING THUNDERSTORMS. MODIFIED
SOUNDINGS THIS AFTERNOON AT LOCATIONS EAST OF THE LARAMIE RANGE
INDICATE LIS OF -3 TO -4 AND CAPES OF 800 TO 1000 J/KG.
THUNDERSTORMS MAY BECOME STRONG AS A RESULT...WITH SMALL HAIL AND
WIND GUSTS TO 40 MPH. HEAVY RAIN WILL AGAIN BE A CONCERN AS
AFTERNOON STORM MOTIONS ARE LESS THAN 10 KNOTS. HOWEVER...COVERAGE
WILL BE LESS AS THE AIR MASS AND PWATS DRY THROUGH THE DAY.
SHOWERS MAY LINGER TONIGHT OVER SOUTHEAST ZONES. THE COLUMN WILL
SLOWLY DRY THROUGH SUNDAY AS WELL. HOWEVER...ISOLATED AFTERNOON
AND EVENING CONVECTION WILL STILL BE POSSIBLE IN SOUTHERN AND
SOUTHEAST ZONES. BY SUNDAY NIGHT...THE UPPER HIGH BEGINS TO BUILD
FURTHER INTO WRN ZONES...BRINGING AN END TO PRECIPITATION
POSSIBILITIES SUNDAY NIGHT. TEMPERATURES WILL WARM INTO THE 70S TO
LOW 80S TODAY. WARMEST TEMPERATURES WILL BE FOUND ACROSS NORTHERN
AND WESTERN LOCATIONS WHERE SUNSHINE MINUTES WILL BE GREATEST.
ANOTHER SEVERAL DEGREES OF WARMING WILL OCCUR ON SUNDAY RETURNING
TEMPERATURES TO MORE SEASONAL LEVELS.

.LONG TERM...MONDAY THROUGH FRIDAY...
THE UPPER RIDGE AXIS WILL MOVE OVER THE UPPER GREAT LAKES REGION
ON MON. MONSOONAL MOISTURE WILL BE LIMITED TO CARBON COUNTY...SO
WILL MENTION A SLIGHT CHANCE OF LATE DAY THUNDERSTORMS IN THIS
AREA...WITH DRY CONDITIONS ACROSS THE REST OF THE CWA. THE UPPER
RIDGE WILL GET FLATTENED ON TUES BY AN UPPER TROUGH MOVING ACROSS
SOUTHERN CANADA. THIS WILL ALLOW MONSOONAL MOISTURE TO SPREAD
FARTHER EAST ACROSS THE CWA...SO WILL GO WITH A SLIGHT CHANCE OF
LATE DAY THUNDERSTORMS IN THE VICINITY OF THE LARAMIE RANGE AND
WEST. THE UPPER RIDGE WILL REBUILD ACROSS THE ROCKIES ON WED. A
DISTURBANCE WILL MOVE SOUTHEAST ACROSS THE CWA WED AND A WEAK
FRONTAL BOUNDARY WILL MOVE ACROSS THE AREA. MID LEVEL MOISTURE
WILL INCREASE WITH THE DISTURBANCE AND BOUNDARY. THIS WILL RESULT
IN A SLIGHT CHANCE OF AFTERNOON AND EVENING THUNDERSTORMS ACROSS
MUCH OF THE CWA. THE UPPER RIDGE AXIS WILL MOVE EAST ACROSS THE
CWA THUR...ALLOWING MORE MOISTURE TO MOVE INTO THE AREA FROM THE
SOUTH...RESULTING IN A CONTINUED CHANCE OF LATE DAY THUNDERSTORMS
ACROSS THE FORECAST AREA. THE UPPER RIDGE WILL ONCE AGAIN GET
FLATTENED ON FRIDAY BY ANOTHER UPPER TROUGH MOVING ACROSS SOUTHERN
CANADA. WILL KEEP A SLIGHT CHANCE OF LATE DAY THUNDERSTORMS IN THE
FORECAST FOR MAINLY THE LARAMIE RANGE AND WEST. HIGH TEMPERATURES
WILL BE FROM 3 TO 6 DEGREES ABOVE NORMAL THROUGH THE PERIOD.

&&

.AVIATION...
VFR CONDITIONS WILL PREVAIL WEST OF THE LARAMIE RANGE TODAY. EAST
OF THE LARAMIE RANGE AREA OF IFR CONDITIONS WILL PREVAIL THIS
MORNING IN RAIN SHOWERS AT KSNY...AND LOW CLOUDS AND FOG IN
KCYS...KBFF...AND KCDR. THUNDERSTORMS WILL BE POSSIBLE THIS
AFTERNOON AND EVENING AT TERMINALS EAST OF THE LARAMIE RANGE. LOW
CLOUDS AND FOG CAN BE EXPECTED TO ROLL IN ONCE AGAIN LATER
TONIGHT.
