AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RIVERTON WY 126 PM MDT TUE JUN 22 2010 SHORT TERM...TONIGHT THROUGH FRIDAY STRONG CIRCULATION STILL SEEN ON WATER VAPOR MOVG INTO SERN ID ATTM WITH BAND OF SHOWERS MOVING ACROSS THE WEST AND BEGINNING TO MOVE INTO CENTRAL WYO. INCREASING INSTABILITY AHEAD OF THIS FEATURE IS ALLOWING FOR STRONG THUNDERSTORMS WITH HAIL UP TO NICKEL SIZE REPORTED SO FAR. LAPS ANALYSIS INDICATES HIGHER CAPE EAST OF THE DIVIDE WITH POTENTIAL FOR SVR STORMS IF CAP BREAKS IN THE NEXT COUPLE HOURS. 18Z SOUNDINGS IS VERY UNSTABLE WITH NEARLY 2000 J/KG AND JUST A SMALL CAP. SPC JUST ISSUED A SVR TSTM WATCH FOR MOST OF OUR ERN ZONES THROUGH 8 PM MDT. WEDNESDAY WILL BE DRY AND WARMER WITH A SHORT PERIOD OF RIDGING. THE WARMING CONTINUES INTO THURSDAY WITH A WEAK WAVE PASSING ACROSS THE NORTH. TEMPERATURES WILL BE QUITE WARM WITH 80S TO AROUND 90 EAST OF THE DIVIDE AND MAINLY 70S WEST WITH MIN RH'S TEENS EAST AND SW WITH 20S TO LOWER 30S NORTH AND NW. MORE SIGNIFICANT TROUGH MOVES INTO THE WEST ON THURSDAY AND THEN INTO IDAHO ON FRIDAY ABOUT 6 HOURS SLOWER THAN OUR CURRENT SYSTEM MOVING THROUGH. MAIN ACTION RIGHT NOW WOULD BE THE NW THIRD BASED ON THIS TIMING BUT THIS WILL HAVE TO BE WATCHED.

LONG TERM...FRIDAY NIGHT THROUGH TUESDAY MEDIUM RANGE MODELS ARE IN DECENT AGREEMENT WITH A WEAK TROUGH MOVING ACROSS THE ROCKIES FRIDAY NIGHT/SATURDAY...WITH THE ASSOCIATED COLD FRONT MOVING ACROSS THE FORECAST AREA LATE FRIDAY/FRIDAY NIGHT. THESE FEATURES WILL ENHANCE CONVECTION CHANCES FRIDAY AND SATURDAY...ESPECIALLY OVER THE NORTHWEST AND NORTHERN SECTIONS OF THE FORECAST AREA...BUT ALL OF THE AREA COULD SEE SOME CONVECTION. TIMING/LOCATION DIFFERENCES IN MODELS PROHIBIT HITTING IN ONE AREA REAL HARD AT THIS TIME. WOULD NOT BE SURPRISED TO SEE SOME STRONG/SEVERE CONVECTION WITH THIS SYSTEM AS GFS IS NOW SHOWING A SLIGHTLY UNSTABLE ATMOSPHERE WITH HIGH LEVEL TOTALS BETWEEN 30 TO 35 ESPECIALLY OVER NORTHERN/EASTERN WYOMING. IN WAKE OF THIS WEAK TROUGH...MEDIUM RANGE MODELS ARE TRENDING TOWARD A STRONG RIDGE DEVELOPING OVER THE PLAINS...WITH A STRONG TROUGH OFF THE PACIFIC NORTHWEST/BRITISH COLUMBIA COASTS EARLY NEXT WEEK. THIS SHOULD RESULT IN MAINLY DRY CONDITIONS AND WARMING TEMPERATURES...WITH THE HOTTEST TEMPERATURES SO FAR THIS YEAR POSSIBLE MONDAY AND TUESDAY...AS BOTH THE 00Z ECMWF AND GFS SHOW 700MB TEMPERATURES BETWEEN 15 AND 19 DEG CELSIUS. AVIATION... A BAND OF THUNDERSTORMS WILL BE TRACKING EAST NORTHEAST ACROSS CENTRAL AND EASTERN WYOMING FOR THE REMAINDER OF THIS AFTERNOON. SOME OF THESE STORMS WILL HAVE THE POTENTIAL FOR PRODUCING LARGE HAIL AND DAMAGING WINDS...ESPECIALLY IN THE NORTHERN BIG HORN BASIN...THE BIG HORN MOUNTAINS...JOHNSON AND NORTHEAST NATRONA COUNTIES. EXPECT SCATTERED MVFR AND ISOLATED IFR CONDITIONS WITH THESE STORMS. HIGH PRESSURE SURFACE AND ALOFT WILL BUILD INTO THE AREA LATER TONIGHT FOR VFR CONDITIONS LATER THIS EVENING THROUGH WEDNESDAY. FIRE WEATHER... ANOTHER WEATHER DISTURBANCE WILL MOVE EAST NORTHEAST ACROSS THE AREA INTO THE EVENING HOURS WITH WIDELY SCATTERED TO SCATTERED THUNDERSTORM COVERAGE AND ADDITIONAL SHOWERS.
