Area Discussion for San Joaquin Valley/Hanford, CA
Hide HelpNOTE: mouseover dotted underlined text for definition
FXUS66 KHNX 032105 AFDHNX
Area Forecast Discussion National Weather Service Hanford CA 205 PM PDT Thu Oct 3 2024
KEY MESSAGES
1. Dry conditions and well above average temperatures will prevail through the week. There is a 70 to 90 percent chance of triple digit heat across much of the San Joaquin Valley on Thursday and a 30 to 80 percent chance of triple digit heat across much of the San Joaquin Valley on Friday.
2. A Heat Advisory remains in effect for the San Joaquin Valley, West Side Hills, and Sierra Foothills through 11 PM PDT Friday.
3. Low afternoon humidity will occur across many locations along with poor to moderate overnight recoveries in the mountains and desert.
4. The Climate Prediction Center's 6-10 and 8-14 day temperature outlooks show a 50 to 70 percent chance for above average temperatures across the region.
DISCUSSION
Satellite loops show sunny skies prevailing over the interior of central California this afternoon. A large area of high pressure extends from the eastern Pacific to the Desert Southwest region.
This pattern produced high temperatures around 15 to 18 degrees above climatological averages across the San Joaquin Valley on Wednesday. In fact, record high maximum temperatures were broken in Merced, Madera, Fresno, and Hanford yesterday. Expect similar temperatures this afternoon with more records likely to be set.
Probability of exceedance for 102 degrees in the SJ Valley today are generally from 55 to 85 percent. An upper trough moves over the Pacific Northwest on Friday while the high pressure focuses over the Four Corners region. Temperatures are forecast to lower a degree or two on Friday with a small reduction in moderate to major heat risk coverage. The Excessive Heat Advisory remains in effect through Friday. The PoE for 102 degrees lowers to around 20 to 40 percent on Friday while the PoE for 100 degrees is from 60 to 80 percent.
Temperatures nudge down another degree or two both Saturday and Sunday. Widespread moderate heat risk persists while the major heat risk coverage continues to decline. The PoE for 100 degrees lowers to 35 to 65 percent on Saturday and 25 to 55 percent on Sunday. Gradual synoptic cooling will occur through next week as an upper trough over the eastern Pacific approaches the coast.
Most areas will stay below the century mark beginning on Monday but will remain several degrees above climatological averages.

VFR conditions will prevail across the Central CA Interior over the next 24 hours.
