NORTHERN GREAT BASIN FORECAST DISCUSSION NATIONAL WEATHER SERVICE ELKO NV 150 PM PDT THU JUL 5 2001 SYNOPSIS...A MOIST SOUTHERLY FLOW WILL CONTINUE ACROSS THE GREAT BASIN. THIS WILL KEEP A RISK OF AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS THROUGH EARLY NEXT WEEK. SHORT TERM...UPPER LEVEL HIGH PRESSURE WILL REMAIN OVER THE ROCKY MOUNTAIN STATES WHILE THE EASTERN PACIFIC TROUGH SPLITS AND REMAINS OFFSHORE BY 48 HOURS. MODELS HAD BEEN TRENDING THIS WAY AND THUS SUPPORTING A CONTINUATION OF DEEP AND MOIST SOUTHERLY FLOW ACROSS CENTRAL AND NORTHERN NEVADA. 12Z SOUNDINGS WERE QUITE WET WITH PRECIPITABLE WATERS OVER AN INCH. MODIFIED FOR AFTERNOON HEATING AND LOCALIZED CONVERGENCE SUGGESTS CAPE IN EXCESS OF 2000 J/KG. MID LEVEL DRYING WAS ALSO OCCURRING FROM THE SOUTHEAST WHICH SUGGESTS FURTHER DESTABILIZATION. SOME STORMS THIS EVENING WILL CONTAIN LARGE HAIL AND LOCALLY HEAVY RAINFALL. FLOW IS STRONG ENOUGH TO PUSH STORMS ALONG SO FLASH FLOOD WILL BE LOCALIZED. MODELS CONTINUE TO SUPPORT MORE OF THE SAME FRIDAY AND SATURDAY ALTHOUGH ADDITIONAL SUPPORT FROM JET DYNAMICS AND ECHO TRAINING COULD PRODUCE MORE OF A FLASH FLOOD THREAT. UPPER JET MOVING INTO THE PACIFIC NORTHWEST IS PROGGED TO BECOME REALIGNED OVER THE NORTHERN ROCKIES WITH NORTHERN NEVADA IN FAVORABLE RIGHT ENTRANCE REGION. ALSO...THE AVN SHOWS ENERGY GETTING CAUGHT UP IN FLOW AND SPREADING NORTHWARD INTO THE GREAT BASIN. WILL CONTINUE WITH HIGH POPS AND NOT ISSUE FLASH FLOOD WATCH AT THIS TIME. THE NGM PLACES BEST CONVECTIVE BANDS OVER EAST CENTRAL WHILE THE AVN/ETA ARE FURTHER NORTH. WILL MENTION A FEW POSSIBLY SEVERE THIS EVENING AND LOCALLY HEAVY RAIN THROUGH FRIDAY. LONG TERM...MEDIUM RANGE MODELS HAVE AGAIN BACKED OFF ANY DRYING TRENDS WITH SPLIT EASTERN PACIFIC FLOW AND ROCKY MOUNTAIN HIGH. A GENERALLY GOOD CONSENSUS AND TRENDS THE PAST FEW DAYS SUGGEST CONTINUING A CHANCE OF THUNDERSTORMS THROUGH THE EXTENDED. HOHMANN .EKO...NONE.
