NWS Salt Lake City, UT wrote its last area forecast discussion before the first event at Jul 4, 2:15 PM MST, 3 hours 45 minutes earlier.
UTAH AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SALT LAKE CITY UT 315 PM MDT WED JUL 4 2001 SYNOPSIS...HOT...DRY HIGH PRESSURE ALOFT OVER UTAH WILL MOVE SLOWLY EAST OF THE STATE THROUGH FRIDAY. THE RESULTANT SOUTHERLY FLOW WILL BRING MOISTURE AND AN INCREASING THREAT OF THUNDERSTORMS THROUGH THE END OF THE WEEK. DISCUSSION...UPPER RIDGE FIRMLY POSITIONED OVER UTAH STILL PROGGED TO DRIFT EAST INTO THE PLAINS STATE BY THE END OF THE WEEK. THIS CHANGE WILL OPEN UP THE INTERMOUNTAIN REGION TO A MORE SOUTHERLY FLOW ALOFT FRIDAY THROUGH AT LEAST SATURDAY. ADEQUATE MOISTURE ALONG WITH ANY WEAK SHORTWAVES EMBEDDED IN THIS FLOW COULD BRING A MARKED INCREASE IN CONVECTION EITHER OF THESE DAYS. DIFFERENTIAL HEATING APPEARS TO BE THE PRIMARY TRIGGER FOR CONVECTION THIS AFTERNOON. DOPPLER RADAR DOES SHOW WIDESPREAD CONVECTION OVER THE CENTRAL MOUNTAINS...WITH A FEW STRONG CELLS NOTED IN THE MIX. SUSPECT AS WITH MOST CONVECTION OF THIS TYPE THAT IT WILL GO TO BED QUICKLY AFTER SUNSET. QUESTION OVER THE NEXT COUPLE OF DAYS WILL BE IF SOME DYNAMIC SUPPORT WILL MATERIALIZE TO FOCUS CONVECTION. THURSDAY MAY TURN ON MUCH LIKE TODAY...BUT AS THE FLOW TURNS MORE SOUTHERLY FRIDAY AND SATURDAY WILL LOOK FOR INCREASED THREAT THOSE TWO DAYS. DEEP LAYER MOISTURE NOT EXPECTED...SO SPOTTY HEAVY PRECIP THE BEST THAT CAN BE EXPECTED FOR NOW. THE CENTER OF THE UPPER HIGH STILL EXPECTED TO MIGRATE BACK TO THE WRN STATES BY THE MIDDLE OF NEXT WEEK. IN TRANSITION WILL LOOK FOR A LITTLE BIT OF DIURNAL MOUNTAIN CONVECTION SUNDAY...THEN AGAIN TUESDAY AND/OR WEDNESDAY. TEMPS...WHICH SHOULD HAVE 'COOLED' BACK TO NEAR NORMAL THIS WEEKEND SHOULD POP BACK UP TO THE HOT AND DUSTY RANGE NEXT WEEK. SLC 2334 CDC 3555 CONGER .SLC...NONE.
