SCTD LIGHT SHOWERS NOTED ON RADAR EARLY THIS MORNING OVER THE SE PART OF THE CWA BUT RECENT TREND HAS BEEN FOR THEM TO DECREASE. EXPECT A LULL IN THE PCPN THIS MORNING THEN MORE WIDESPREAD SHOWERS AND THUNDERSTORM ACTIVITY EXPECTED THIS AFTERNOON AS SFC WINDS ACQUIRE A MORE EAST OR SOUTHEASTERLY FLOW WHICH WILL TRANSPORT HIGHER MOISTURE VALUES OVER THE CWA EAST OF THE MTNS AS WELL AS ENHANCE SHEAR SOMEWHAT. WEAK IMPULSES RIDING OVER THE CWA WILL HELP TO KICK THINGS OFF THIS AFTERNOON WITH ACTIVITY LIKELY PERSISTING THROUGH MUCH OF THE NIGHT AS INSTABILITIES HOLD. A FEW STRONG TO SEVERE STORMS POSSIBLE MAINLY OVER THE PANHANDLE THIS AFTERNOON INTO EARLY THIS EVENING AS WELL. MORE OF THE SAME TUESDAY AS PATTERN CHANGES LITTLE WITH MONSOONAL MOISTURE CONTINUING TO STREAM ACROSS THE AREA. SOME HEAVY RAINFALL A DECENT POSSIBILITY OVER THE NEXT COUPLE DAYS WITH TUESDAY LOOKING THE BETTER BET AS PRECIPITABLE WATER VALUES INCREASE TO NEAR 1.5 INCHES EAST OF THE MTNS.

MOISTURE DOES NOT APPEAR TO BE AS PLENTIFUL FOR THIS PORTION OF THE FORECAST AS THAT OF TODAY AND TUESDAY. PRECIPITABLE WATER VALUES LOWER SOME AND ARE GENERALLY BETWEEN ONE HALF INCH AND ONE INCH. THE MID AND UPPER LEVEL MOISTURE PLUME WILL GENERALLY BE OVER THE SOUTHEAST HALF OF THE CWA FOR WEDNESDAY THROUGH SUNDAY. THE ECMWF CONTINUES TO PLACE THE PLUME FURTHER WEST THAN THE GFS. A SCATTERED COVERAGE OF MAINLY AFTERNOON AND EVENING THUNDERSTORMS SHOULD BE THE RESULT EACH DAY. BUT WITH LESS MOISTURE AVAILABLE...THE ACTIVITY SHOULD BE LESS WIDESPREAD AND PRODUCE LIGHTER RAINFALL AMOUNTS. GUSTY SOUTHWEST WINDS WILL AFFECT THE AREAS ALONG AND WEST OF THE LARAMIE RANGE DURING THE DAYTIME HOURS EACH DAY. && .AVIATION...12Z TAF ISSUANCE... SHOWERS AND LATE DAY THUNDERSTORMS WILL AFFECT THE CWA THROUGH TUESDAY. SOME OF THE STORMS WILL BE STRONG AND WILL HAVE MVFR CEILINGS AND VISIBILITIES IN RAIN ASSOCIATED.

NO BIG CONCERNS ANTICIPATED THROUGH THE EARLY PART OF THE WEEK WITH DECENT CHANCES FOR MAINLY AFTERNOON AND NIGHTTIME SHOWERS AND THUNDERSTORMS AS MONSOONAL MOISTURE CONTINUES TO RIDE OVER THE REGION. FUELS REMAIN MOSTLY GREEN AND NON CRITICAL AND ADDITIONAL RAINS WILL KEEP THEN THAT WAY FOR A WHILE TO COME. && .HYDROLOGY... FLOOD WARNINGS EARLY THIS MORNING CONTINUE FOR THE UPPER NORTH PLATTE RIVER AT SARATOGA AND SINCLAIR AND THE LARAMIE RIVER AT LARAMIE. ALL OF THOSE GAGE SITES ARE EXPECTED TO DROP BELOW FLOOD STAGE LATER TODAY. THE GENERAL TREND ON ALL RIVERS AND STREAMS IN THE CWA WILL BE SLOWLY FALLING WATER LEVELS THROUGH THIS NEXT WEEKEND AND BEYOND. MONSOONAL MOISTURE WILL CONTINUE TO RESULT IN LATE DAY THUNDERSTORMS ESPECIALLY THROUGH TUESDAY. THE ACTIVITY WILL BE LESS WIDESPREAD AND PRODUCE LIGHTER RAINFALL AMOUNTS OVER THE SOUTHEAST HALF OF THE CWA WEDNESDAY AND THROUGH THE UPCOMING WEEKEND.
