Area Forecast Discussion National Weather Service Sacramento CA 1235 AM PDT Wed Jun 19 2024

SYNOPSIS
Dry, seasonable weather today with slightly higher relative humidity helped by onshore flow. A warming trend is expected from late week and into the weekend.

Key Points - Generally seasonable temperatures continue through Thursday, much warmer Friday into the weekend.
- Widespread Moderate HeatRisk is expected from Friday through Sunday, with some Major HeatRisk in the foothills and Shasta county on Saturday.

Short-Term Discussion (Today THROUGH Saturday)...
Ensembles and clusters indicate that weak upper level trough will remain over NorCal through Thursday. Trough will weaken and gradually transition into a ridge during the weekend, as upper high strengthens over the Desert Southwest. This will keep Valley high temperatures near normal levels today, warming to slightly above normal Thursday in the 90's, before heating up to well above normal levels from the upper 90's to low 100's Friday and Saturday.

Widespread Moderate HeatRisk is expected to start Friday and will continue through the weekend. Currently probabilities of Sacramento Valley locations (north of Sacramento metropolitan area) reaching at least 100 degrees on Friday are 50 to 90%. From the Sacramento metropolitan area and southward into the northern San Joaquin Valley, chances are generally lower, at 15 to 50% probability.

Outside of the developing heat, winds will generally be light helping to reduce critical fire weather conditions a bit, despite lowering relative humidity Friday and especially Saturday.

.EXTENDED DISCUSSION (Sunday THROUGH Wednesday)...
Desert SW high continues to build NW into NorCal over the weekend resulting in widespread triple digit heat in the Central Valley with 80s to around 102 in the mountains and foothills. Upper low near VRISL early next week will lower heights some over NorCal Mon/Tue with upper 90s to around 102 expected in the Central Valley. Short wave trough progresses east Wednesday allowing high temperatures to warm back up 2 to 4 degrees.

AVIATION
VFR conditions over interior NorCal next 24 hrs. Sfc wind mainly below 12 kts except vcnty of Delta SWly sfc wind 15-25 kts.



STO WATCHES/WARNINGS/ADVISORIES
