038 FXUS66 KHNX 250824 AFDHNX Area Forecast Discussion National Weather Service Hanford CA 124 AM PDT Wed Sep 25 2024 .KEY MESSAGES... 1. Dry conditions and warmer than average temperatures prevail for the next several days. 2. A minor cooling trend will take place today and Thursday, and temperatures warm back up on Friday and Saturday. 3. Low afternoon humidity will occur, even with the slight moderation in temperatures today and Thursday, in many locations along with poor to moderate overnight recoveries in the mountains and desert. && .DISCUSSION... A dry southwest flow will be aloft today with high pressure slightly weakening due to a shortwave trough passing over Northern California. High temperatures today will lower to the mid to upper 90`s at the warmest locations and slightly lower into Thursday. The probability of highs reaching at least 95 degrees for this afternoon is around 30 to 60 percent at locations mainly south of Fresno County while higher for the Kern County desert. Triple digits are unlikely in our forecast area today, except in the Indian Wells Valley, or Ridgecrest/Inyokern, where there is up to a 20 percent chance. Otherwise, expect another warm, dry today and for the next several days. Another warming trend is in store for Friday and Saturday due to the ridge of high pressure rebuilding. The probabilities of readings at or above 95 degrees rise a bit, at least in the Central Valley, including around 40 to 65 percent chance on Friday and 50 to 80 percent chance on Saturday. There is a decent probability for a return of triple digits towards northeastern Kern County on Friday and Saturday (about 40 to 60 percent). Much lower chances for readings in the mid-90`s occur Sunday into Monday, however, the likelihood rebounds on Tuesday and next Wednesday, just in time for October. The ridge will once again strengthen by the middle of next week, so expect at least one more minor warmup. The warm, dry pattern continues through the foreseeable future, while relative humidity will be low in the afternoons along with poor to moderate overnight recoveries in the mountain and desert areas. Winds will be generally light with some local afternoon breezes over some of the ridgetops. && .AVIATION...VFR conditions will prevail across the central CA interior over the next 24 hours. && .AIR QUALITY ISSUES...
