VERY HOT AND DRY CONDITIONS WILL CONTINUE THROUGH EARLY NEXT WEEK AS AN INTENSE HEAT WAVE BUILDS OVER THER REGION. PERIODIC AFTERNOON BREEZES CAN BE EXPECTED BUT NO LARGE SCALE STRONG WINDS ARE FORECAST. DAILY MIN RH VALUES IN THE SINGLE DIGITS ARE LIKELY OUTSIDE OF THE HIGHEST ELEVATIONS, WITH MINIMAL OVERNIGHT RECOVERY. ...DISCUSSION FROM LAXFWFSGX... THE LONG-DURATION PERIOD OF HOT AND DRY WEATHER ACROSS SOUTHERN CALIFORNIA WILL AID IN A PERSISTENT DOWNWARD TREND IN BOTH DEAD AND LIVE FUEL MOISTURE. THE LOW HUMIDITY COMBINED WITH GUSTY SEA BREEZE WINDS WILL BRING ELEVATED TO NEAR CRITICAL FIRE WEATHER CONDITIONS EACH AFTERNOON AND EVENING. THE MARINE LAYER WILL KEEP AREAS NEAR THE COAST COOLER WITH HIGHER HUMIDITY. AS EVIDENCED BY THE RECENT KITCHEN, MCCAIN, AND NUMEROUS OTHER FIRES, LOCAL GRASS FUELS ARE CURED AND VERY AVAILABLE TO BURN. THE PRIMARY FACTORS LIMITING ANY MORE CRITICAL FIRE WEATHER POTENTIAL ARE A LACK OF STRONG WINDS (OUTSIDE OF THE TYPICAL DIURNALLY-DRIVEN WINDS) ANY GIVEN DAY, AS WELL AS LIVE FUEL MOISTURE. LIVE FUEL MOISTURE WILL, HOWEVER, BE STEADILY DROPPING/DRYING OUT AS WE HEAD THROUGH THE WEEKEND AND INTO EARLY NEXT WEEK. THIS WILL INCREASE THE ABILITY OF LARGER FUELS LIKE BRUSH, CHAPARRAL, AND TREES TO BURN. ENERGY RELEASE COMPONENTS ARE STEADILY TRENDING UPWARD TOWARD THE 40TH PERCENTILE AND EXPECTED TO APPROACH THE 45TH-50TH PERCENTILE NEXT WEEK. ...DISCUSSION FROM PHXFWFPSR... DRIER CONDITIONS WILL CONTINUE TO FILTER INTO THE REGION THROUGH THURSDAY LEAVING ONLY SLIGHT CHANCES FOR SOME SHOWERS AND MAYBE A WEAK THUNDERSTORM ACROSS THE EASTERN ARIZONA HIGH TERRAIN THIS AFTERNOON. RAIN CHANCES WILL GENERALLY COME TO AN END ALTOGETHER STARTING THURSDAY. AS CONDITIONS CONTINUE TO DRY OUT, HOTTER TEMPERATURES ARE EXPECTED WITH EXCESSIVE HEAT SPREADING EASTWARD THROUGH MUCH OF ARIZONA. MINRH VALUES ACROSS THE LOWER DESERTS WILL FALL TO AROUND 15% TODAY, WHILE HIGHER TERRAIN AREAS EAST OF PHOENIX SEE 20-25%. EVEN LOWER RHS ARE EXPECTED THURSDAY INTO FRIDAY. WINDS WILL FOLLOW DIURNAL TRENDS, OCCASIONALLY GUSTING TO 20 MPH DURING THE AFTERNOON HOURS. THE COMBINATION OF THE VERY HOT AND DRY CONDITIONS WILL LEAD TO AN INCREASED FIRE DANGER THREAT. ##################################################################### ## ## ## AFTER REVIEWING THE FWF DISCUSSIONS (ABOVE) - COMPLETE ## ## THE DISCUSSION (BELOW) FOR THE ECCDA FORECAST ## ## WHEN DONE CLICK TRANSMIT, PRODUCT SENT AS KVEFFWLVEF ## ## ## ##################################################################### ECC027-041500- SAN BERNARDINO ECC DISPATCH- DISCUSSION FOR SAN BERNARDINO ECC DISPATCH 149 PM PDT WED JUL 3 2024 VERY HOT AND DRY CONDITIONS WILL CONTINUE THROUGH EARLY NEXT WEEK AS AN INTENSE HEAT WAVE BUILDS OVER THER REGION.
