ABOVE NORMAL TEMPERATURES AND DRY CONDITIONS WILL CONTINUE THROUGH SATURDAY, WITH MINIMUM AFTERNOON HUMIDITIES IN THE SINGLE DIGITS AND POOR OVERNIGHT RECOVERIES. WIND GUSTS OF 15 TO 25 MPH WILL BE COMMON DURING THE AFTERNOONS. MOISTURE WILL BEGIN TO INCREASE ON SUNDAY WITH INCREASING SHOWER AND THUNDERSTORM CHANCES TO START THE WEEK. CONDITIONS WILL FAVOR DRY THUNDERSTORMS INITIALLY BUT DEEPER MOISTURE IS LIKELY AS THE WEEK GOES ON. ...DISCUSSION FROM LAXFWFSGX... VERY DRY FOR THE DESERTS INTO THE MOUNTAINS THROUGH FRIDAY WITH LOWEST HUMIDITY FALLING TO AROUND 6 TO 10 PERCENT EACH DAY AND MODERATE OVERNIGHT RECOVERIES. SUBTLE COOLING OCCURS BY THIS WEEKEND. THE FLOW ACROSS THE AREA BECOMES SOUTHEASTERLY FOR SUNDAY INTO MUCH OF NEXT WEEK ALLOWING FOR AN INFLUX OF MONSOONAL MOISTURE AND HIGHER HUMIDITY FOR ALL AREAS. DURING THIS PERIOD, WE CAN EXPECT DAILY CHANCES FOR SHOWERS AND THUNDERSTORMS OVER THE MOUNTAINS, DESERTS AND LOCALLY INTO THE FAR EASTERN VALLEYS EACH AFTERNOON AND EVENING. ...DISCUSSION FROM PHXFWFPSR... GUSTY THUNDERSTORM OUTFLOW WINDS FROM THE EAST, ALTHOUGH TO A LESSER EXTENT COMPARED TO PREVIOUS DAYS, OVER THE FAR EASTERN DISTRICTS WILL BE THE MAIN FIRE WEATHER CONCERN THROUGH FRIDAY. OTHERWISE, AFTERNOON HUMIDITY LEVELS WILL GENERALLY FALL IN A 10-20% RANGE WITH THE UPPER END OF THE RANGE OVER EASTERN DISTRICTS. OVERNIGHT RECOVERY WILL GENERALLY RANGE BETWEEN 30-60%, WITH THE UPPER END OF THE RANGE OVER THE IMPERIAL VALLEY AND THE EASTERN DISTRICTS. ##################################################################### ## ## ## AFTER REVIEWING THE FWF DISCUSSIONS (ABOVE) - COMPLETE ## ## THE DISCUSSION (BELOW) FOR THE ECCDA FORECAST ## ## WHEN DONE CLICK TRANSMIT, PRODUCT SENT AS KVEFFWLVEF ## ## ## ##################################################################### ECC027-101430- SAN BERNARDINO ECC DISPATCH- DISCUSSION FOR SAN BERNARDINO ECC DISPATCH 122 PM PDT THU JUL 9 2026 ABOVE NORMAL TEMPERATURES AND DRY CONDITIONS WILL CONTINUE THROUGH SATURDAY, WITH MINIMUM AFTERNOON HUMIDITIES IN THE SINGLE DIGITS AND POOR OVERNIGHT RECOVERIES.

A warmer and drier airmass setting up across the region will persist through early next week. While we are not expecting extreme heat, fuels will continue to dry out. In addition, mid-to- upper level monsoonal moisture surge from the south brings the potential for high based thunderstorms Sunday and Monday. This is a low confidence, low probability but potentially high impact scenario if we see elevated convection develop over the Bay Area and Central Coast. Any elevated thunderstorms that do develop could lead to dry lightning and gusty, erratic outflow winds. Remain aware of the thunderstorm potential through the weekend into the beginning of next week. ...Discussion from SFOFWFEKA... Clear, dry, and hot weather will continue for interior valleys this afternoon through Friday. A large ridge of high pressure building over the region will push temperatures up into the mid to upper 90s. At the same time, humidity levels during the day will drop quite low into the teens and 20s. This dry air will quickly dry out the brush and grass in the forests, which increases the fire danger. Winds will stay mostly light and follow normal daily patterns, blowing gently up the mountain slopes in the afternoon. The immediate coast will be protected from this heat by a cool, damp layer of ocean clouds and fog, which will allow for excellent humidity recovery overnight. Looking ahead to next week, we are tracking a stronger heatwave inland, along with a small chance of moisture moving up from the south that could bring a risk of lightning to the northeastern mountains. ##################################################################### ## ## ## Complete a discussion for each ECCDA segment below ## ## When done click transmit, product sent as KMTRFWLMTR ## ## ## ##################################################################### ECC010-100900- St Helena ECC Dispatch- DISCUSSION FOR Marin and Sonoma and Napa Counties 155 PM PDT Thu Jul 9 2026 A warmer and drier airmass setting up across the region will persist through early next week.
