Area forecast discussion, Jun 13, 10:45 AM MST, 1 hour 9 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RIVERTON WY 1145 AM MDT THU JUN 13 2013 .SHORT TERM...THURSDAY THROUGH SATURDAY NIGHT THE SEVERE WEATHER OF YESTERDAY HAS ENDED. HOWEVER IT DOES NOT LOOK LIKE WE ARE OUT OF THE WOODS COMPLETELY YET. RADAR DOES SHOW SOME SHOWERS AND EMBEDDED THUNDER ACROSS EASTERN IDAHO AND INTO NORTHWESTERN WYOMING IN ASSOCIATION WITH YET ANOTHER SHORTWAVE AND A JET STREAK PROVIDING SOME LIFT. ORIENTATION OF THE SHOWERS AND THUNDERSTORMS MAY BE A BIT DIFFERENT TODAY AS A COLD FRONT SLOWLY MOVES ACROSS THE AREA AHEAD OF AN APPROACHING TROUGH. THE NAM DOES SHOW A SURGE OF MOISTURE MOVING IN OUT OF UTAH. WATER VAPOR IMAGERY ALSO SHOWS A SURGE OF MOISTURE WITH A BIT MORE JET ENERGY SO WE HAVE ADDED SOME LATE MORNING AND AFTERNOON CONVECTION TO SOUTHERN WYOMING OVER TO AROUND CASPER. FURTHER NORTH...THE ATMOSPHERE IS A BIT MORE CAPPED SO THE SHOW MAY BE LATER THERE. HOWEVER...THIS WILL ALLOW FOR MORE EXPLOSIVE DEVELOPMENT OF ANY THUNDERSTORMS. WITH UPPER LEVEL DIFLUENCE AND STILL SOME GOOD DIRECTIONAL SHEAR SOME STRONG THUNDERSTORMS ARE ONCE AGAIN POSSIBLE...MAINLY ACROSS PORTIONS OF JOHNSON COUNTY AND ACROSS THE BIG HORN RANGE TO THE BIG HORN BASIN WHICH IS WHERE THE DEEPEST MOISTURE AND SHEAR CONTINUE TO PRESIDE. THE MAIN THREATS ONCE AGAIN WOULD BE LARGE HAIL AND DOWNBURST WINDS. THE THREAT OF STORMS SHOULD TAPER OFF LATER AT NIGHT AS DRIER AIR MOVES IN FROM THE WEST. THE OTHER THREAT TODAY WILL BE WIND. PROBABLY NOT HIGH WIND CRITERIA...ALTHOUGH THERE COULD BE SOME GUSTS TO 40 TO 50 MPH...MAINLY ACROSS SOUTHERN WYOMING AND NORTH INTO PORTIONS OF FREMONT AND NATRONA COUNTIES WITH THE TIGHTENING PRESSURE GRADIENT AHEAD OF THE COLD FRONT. QUIETER AND COOLER WEATHER WILL BE THE RULE FOR FRIDAY AS A COOLER AIR MASS MOVES INTO MOST OF WYOMING. PRECIPITABLE WATERS DROP SIGNIFICANTLY TO UNDER 0.5 FOR MOST AREAS TOMORROW SO THE CHANCE OF CONVECTION WILL BE MUCH LESS. AN APPROACHING TROUGH WILL LIFT TO THE NORTH AND FLATTEN OUT BUT MAY BE CLOSE ENOUGH TO TOUCH OF AN ISOLATED SHOWER OR THUNDERSTORM ACROSS FAR NORTHERN AREAS BUT MOST AREAS WILL BE MAINLY DRY. SATURDAY ALSO LOOKS TO BE A MAINLY QUIET DAY WITH NEAR NORMAL TEMPERATURES AS RIDGING BEGINS TO BUILD TO THE WEST OF WYOMING ONCE AGAIN. ONE POSSIBLE SMALL FLY IN THE OINTMENT MAY BE SOME DEEPER MOISTURE TRYING TO SNEAK INTO FAR EASTERN PORTIONS OF THE COUNTY WARNING AREA. THIS COULD TOUCH OFF A STRAY SHOWER OR THUNDERSHOWER BUT WE WILL KEEP THE FORECAST DRY FOR NOW. .LONG TERM...SUNDAY THROUGH THURSDAY AT THE START OF THIS PERIOD...AN UPPER RIDGE OF HIGH PRESSURE WILL BE CENTERED NEAR THE CONTINENTAL DIVIDE DOWNSTREAM OF AN UPPER LOW OFF THE NW COAST...AROUND 45N 135W. THIS UPPER PATTERN WILL PROGRESS SLOWLY THROUGH THIS PERIOD WITH UPPER LOW PUSHING ONTO NW COAST TUESDAY NIGHT AND UPPER RIDGE SHIFTING INTO THE PLAINS. UPPER LOW THEN IS EXPECTED TO SHEAR NE UP BACKSIDE OF RIDGE ACROSS THE NORTHERN ROCKIES ON THURSDAY. CONTINUED OVERALL DRY CONDITIONS ACROSS SOUTH AND CENTRAL WYOMING WILL RESULT IN HEIGHTENED FIRE WEATHER CONCERNS. ON SUNDAY...MOISTURE AND SLIGHT INSTABILITY WILL LIE ALONG AND NORTH OF A STATIONARY FRONTAL BOUNDARY ACROSS THE NORTH AND EAST...WITH ISOLATED AFTERNOON/EVENING THUNDERSTORMS NORTH OF THIS BOUNDARY...AND DRY WEATHER WITH SEASONABLY MILD WEATHER ACROSS THE CENTRAL AND SOUTH. ON MONDAY...SURFACE HIGH PRESSURE BUILDING INTO THE PLAINS WILL RESULT IN AN EASTERLY FLOW BRINGING IN BETTER MOISTURE AND INSTABILITY/CHANCES FOR AFTERNOON AND EVENING THUNDERSTORMS...MAINLY ACROSS NATRONA AND JOHNSON COUNTIES. TUESDAY AND WEDNESDAY...A DRY AND WARM SW FLOW WILL PREVAIL ACROSS MOST OF THE AREA...BREEZY TO WINDY CONDITIONS ALONG WITH INCREASING FIRE WEATHER CONCERNS ACROSS THE SOUTH AND CENTRAL. ISOLATED THUNDERSTORMS WILL BE POSSIBLE ACROSS THE NORTH. THURSDAY...COLD FRONTAL PASSAGE. COOLER HIGH TEMPERATURES WITH A CONTINUED SLIGHT CHANCE OF THUNDERSTORMS ACROSS THE NORTH. && .AVIATION.../18Z ISSUANCE/ HIGH BASED SHOWERS AND THUNDERSTORMS WILL BE A THREAT THIS AFTERNOON FOR ALL TERMINALS IN THE FORECAST AREA SOUTH OF A KJAC TO KCPR LINE...WITH POSSIBLE BRIEF SEVERE WINDS IN EXCESS OF 50 KTS POSSIBLE THROUGHOUT THE AFTERNOON AND THROUGH THE EVENING PERIOD. STORMS NORTH OF THIS LINE WILL BE ABLE TO ATTAIN STRONGER CHARACTERISTICS WITH BRIEF BUT VERY STRONG TO SEVERE ERRATIC WINDS AND GS POSSIBLE ALONG WITH BRIEF MVFR/IFR CONDITIONS. && .FIRE WEATHER... A COUPLE OF UPPER LEVEL DISTURBANCES WILL SWING UP THROUGH THE REGION TODAY WITH THE POSSIBILITY OF PRODUCING SOME STRONGER STORMS ACROSS THE NORTHERN QUARTER OF WYOMING. THE CHANCE OF THUNDERSTORMS MAY MOVE FURTHER SOUTH TODAY ALTHOUGH STORMS SHOULD BE ISOLATED IN THESE AREAS. GUSTY WEST TO SOUTHWEST WINDS WILL CONTINUE ACROSS THE FAVORED AREAS IN THE SOUTHWESTERN WIND CORRIDOR. EXPECT A QUIETER AND COOLER DAY ON FRIDAY AFTER THE PASSAGE OF A COLD FRONT. && .RIW WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...HATTINGS LONG TERM...AEM AVIATION...BRAUN FIRE WEATHER...HATTINGS
