Wyoming Fire Weather Zone 289

.DISCUSSION...

...YELLOWSTONE NP AND TETON DISPATCH AREAS (INCLUDES FIRE WEATHER
ZONES 140...414...415...AND 416)...

EXPECT WARMER AND DRIER WEATHER TODAY WITH RIDGING BUILDING ACROSS
THE AREA. THERE COULD STILL BE ISOLATED SHOWERS AND THUNDERSTORMS
THIS AFTERNOON AND EVENING BUT THESE SHOULD BE CONFINED TO THE
HIGHER ELEVATIONS. AN APPROACHING SHORTWAVE WILL BRING ANOTHER
CHANCE OF SHOWERS AND THUNDERSTORMS WEDNESDAY AFTERNOON AND
EVENING...SOME OF WHICH COULD BE QUITE STRONG. WINDS WILL TURN MORE
SOUTHERLY TODAY THROUGH WEDNESDAY.

...RAWLINS DISPATCH AREA (INCLUDES FIRE WEATHER ZONES 277...278...
AND 279)...

ANY SHOWERS WILL END EARLY THIS MORNING WITH MAINLY DRY WEATHER FOR
THE BALANCE OF THE DAY. WINDS WILL ALSO BE LESS THAN YESTERDAY AND
MAINLY FROM THE WEST AND SOUTHWEST.  A FEW THUNDERSTORMS WILL THE
RETURN TO THE AREA WEDNESDAY ALONG WITH A GUSTY SOUTHERLY WIND.

...CODY DISPATCH AREA (INCLUDES FIRE WEATHER ZONES 275...276...
282...283...285...286...287...288...AND 289)...

WINDS WILL DECREASE TODAY AND TEMPERATURES WILL REBOUND AS A RIDGE
BUILDS INTO THE AREA. RELATIVE HUMIDITY WILL BE LOWER...BUT STILL
ABOVE NORMAL FOR THIS TIME OF YEAR. THERE COLD STILL BE AN ISOLATED
SHOWER OR THUNDERSTORM OVER THE HIGHER ELEVATIONS OF THE MOUNTAINS.
ANOTHER DISTURBANCE WILL MOVE TOWARD THE AREA FOR WEDNESDAY AND
BRING ANOTHER CHANCE OF AFTERNOON AND EVENING SHOWERS AND
THUNDERSTORMS...SOME OF WHICH COULD BE LOCALLY STRONG.

...CASPER DISPATCH AREA (INCLUDES FIRE WEATHER ZONES 280...281...
285...289...AND 300)...

ANY SHOWERS SHOULD END EARLY THIS MORNING WITH THE BALANCE OF THE
DAY RELATIVELY WARM AND DRY WITH ONLY A SLIGHT CHANCE OF SHOWERS
OVER THE HIGHER ELEVATIONS. RELATIVE HUMIDITY WILL BE LOWER...BUT
STILL ABOVE NORMAL FOR THIS TIME OF YEAR. ANOTHER DISTURBANCE WILL
MOVE TOWARD THE AREA FOR WEDNESDAY AND BRING ANOTHER CHANCE OF
AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS...SOME OF WHICH
COULD BE LOCALLY STRONG.

...THUNDERSTORMS IMPLY STRONG GUSTY AND ERRATIC WINDS...
...HAINES INDEX IS HIGH LEVEL HAINES BOTH DAY AND NIGHT...
