Area forecast discussion, Jul 17, 2:11 PM MST, 1 hour 59 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 311 PM MDT THU JUL 17 2008 .SHORT TERM...TONIGHT THROUGH SATURDAY. SCATTERED THUNDERSTORMS WILL CONTINUE THIS AFTERNOON AND INTO THE EVENING AS SHORT-WAVE ENERGY ALOFT MOVES ALONG THE COLORADO AND WYOMING STATE LINE. STRONGEST INSTABILITY WILL BE OVER THE NEBRASKA PANHANDLE...AND MAINLY EAST OF THE FORECAST AREA EVEN THOUGH LOW LEVEL MOISTURE WILL STILL BE ABUNDANT. HOWEVER...THUNDERSTORMS EARLY THIS AFTERNOON HAVE ALREADY BEEN STRONG AND PRODUCING LOCALIZED HEAVY RAINFALL...ACROSS PORTIONS OF THE SOUTHERN NEBRASKA PANHANDLE. INSTABILITY ACROSS THE WEST WILL DECREASE OVERNIGHT AND PRECIPITATION CHANCES WILL DIMINISH THERE...BUT WILL KEEP CHANCES FOR PRECIPITATION IN PLACE OVERNIGHT WITH LOW LEVEL CONVERGENCE AND ABUNDANT LOW LEVEL MOISTURE PRESENT EAST OF THE LARAMIE RANGE. HAVE ALSO ADDED THE MENTION OF PATCHY FOG AND LOW CLOUDS ACROSS MUCH OF THE AREA EAST OF THE LARAMIE RANGE FOR EARLY FRIDAY. ALTHOUGH THE STORM PREDICTION CENTER HAS INCLUDED THE FORECAST AREA IN A SLIGHT RISK FOR SEVERE THUNDERSTORMS FRIDAY...BELIEVE THAT THE SHORT-WAVE ENERGY ALOFT SHOULD ALLOW MOST OF THE SEVERE CONVECTION TO REMAIN OVER NORTHEAST WYOMING. HAVE CONTINUED TO MENTION SCATTERED THUNDERSTORMS IN ALBANY COUNTY AND ALONG AND EAST OF THE LARAMIE RANGE FOR THE LOW LEVEL MOISTURE AND CONVERGENCE PRESENT...WITH LESS SHEAR EXPECTED THAN ACROSS NORTHEAST WYOMING. PRECIPITATION CHANCES WILL MOVE EAST OF THE AREA FRIDAY NIGHT AS MID-LEVEL DRY AIR INCREASES AND THE RIDGE ALONG THE PACIFIC COAST BEGINS TO AMPLIFY. THE UPPER LEVEL RIDGE THEN SHIFTS EAST SATURDAY IN THE WAKE OF A STRONGER UPPER LEVEL SHORT-WAVE ALONG THE CANADIAN BORDER. 700 MB TEMPERATURES INCREASE SIGNIFICANTLY SATURDAY...ALLOWING FOR ASSOCIATED SURFACE WARMING TREND TO TAKE HOLD INTO THE WEEKEND. THIS WILL CREATE AFTERNOON HIGH TEMPERATURES IN THE LOWER 90S FOR MOST LOWER ELEVATION AREAS SATURDAY. MODEL SOUNDINGS INDICATE THE ATMOSPHERE WILL BE EXTREMELY DRY WEST OF THE PERSISTENT SURFACE TROUGH EAST OF THE LARAMIE RANGE...SO WILL JUST LEAVE IN A SLIGHT CHANCE FOR THUNDERSTORMS IN THE NEBRASKA PANHANDLE AND NIOBRARA COUNTY FOR SATURDAY AFTERNOON. .LONG TERM...SATURDAY NIGHT THROUGH THURSDAY... KEPT A FEW TSTMS AT FAR EASTERN PART OF CWA EARLY SATURDAY EVENING. OTHERWISE... CLEARING WILL OCCUR FROM WEST TO EAST AS SYSTEM OVER NORTHERN PLAINS MOVES ON TO THE EAST. AFTER THIS...UPPER RIDGE WILL BUILD BACK OVER THE ROCKIES FOR SUNDAY AND MONDAY BRINGING WARMER TEMPS AGAIN AND MAINLY DRY CONDITIONS. BOTH GFS AND NAM SHOW A LITTLE MOISTURE RETURNING TO SOUTHERN MOUNTAINS OF WY AND EVEN SOME TO NORTHEAST EDGE OF CWA. FOR NOW...HAVE ADDED A LOW POP FOR TSTMS TO THE MOUNTAINS BOTH DAYS. UPPER RIDGE SHIFTS A BIT TO THE EAST AND FLOW ALOFT BECOMES SW TUE THROUGH THU. UPPER HIGH THAT WAS OVER CO ON SUNDAY MOVES INTO SOUTHERN PLAINS STATES BY MIDWEEK. THIS WILL ALLOW MONSOON MOISTURE TO SPREAD NNE INTO OUR CWA... AND HAVE INCLUDED LOW POPS FOR TSTMS OVER SOUTHERN AND PARTS OF EASTERN CWA TUE THROUGH THU. && .AVIATION... VFR CONDITIONS WILL PREVAIL THIS AFTERNOON AND EVENING WITH THE EXCEPTION OF LOCALIZED MVFR NEAR THE STRONGEST THUNDERSTORMS. AREAS OF IFR WILL DEVELOP LATE TONIGHT AS LOW STRATUS CLOUDS AND PATCHY FOG DEVELOP EAST OF THE LARAMIE RANGE. IFR CONDITIONS ARE EXPECTED TO DIMINISH BY AROUND 15Z FRIDAY...WITH LOCALIZED MVFR CONDITIONS AGAIN DEVELOPING NEAR SHOWERS AND THUNDERSTORMS. && .FIRE WEATHER... EXPECT CARBON COUNTY TO EXPERIENCE DECREASING RELATIVE HUMIDITIES AND INCREASING WIND SPEEDS DURING THE AFTERNOON FRIDAY. AT THIS TIME...WIND SPEEDS SHOULD REMAIN BELOW RED FLAG CRITERIA BUT CONDITIONS WILL BECOME MORE FAVORABLE FOR DANGEROUS FIRE GROWTH. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE.
