Area Forecast Discussion National Weather Service Hanford CA 400 AM PDT Sat Jul 11 2020

SYNOPSIS. A strong ridge of high pressure over the Desert Southwest will bring widespread triple digit heat to the San Joaquin Valley, lower foothills and Kern County desert through Monday. The ridge will weaken some next week but temperatures will remain a little above normal with continued dry weather.

DISCUSSION. Satellite loops show clear skies over the central California interior this morning as anticyclonic flow prevails over the region. A strong ridge of high pressure aloft centered over New Mexico brought widespread triple digit heat to the lower elevations on Friday with max temperatures around 3-5 degrees above normal. The upper ridge will build westward over southern California today bringing further warming to the district. The ridge holds strong through Sunday with perhaps another degree or two of warming. By Monday the ridge is expected to weaken a bit as an upper trough moves over the Northwest. This will lower temperatures slightly, but temps are still expected to be several degrees above normal. These conditions from today through Monday will pose a moderate to high heat risk for the population with Sunday forecast to be the hottest day. A Heat Advisory is in effect for the San Joaquin Valley, the Sierra Nevada Foothills, and the West Side Hills today through Monday. High temperatures are forecast between 100-109 degrees for the SJ Valley and from 95-105 degrees in the adjacent foothills. An Excessive Heat Warning is in effect for the Indian Wells Valley and Kern County Desert today through Monday. High temperatures there are forecast between 104-113 degrees. The hottest areas are forecast to have very high heat risk on Sunday, especially across the Indian Wells Valley. Area rivers and streams might seem very inviting to cool off from the heat, but they can be extremely dangerous too. The waters are still cold and swift and venturing into them can result in drowning or water rescue.

The center of the ridge gets displaced over West Texas Tuesday and remains there the rest of next week. Temperatures lower a few more degrees on Tuesday then little changes through Friday. High temperatures across the SJ Valley look to hover within a couple degrees either side of the century mark next Tues-Fri, around 2-5 degrees above normals for mid July.

Moisture wrapping around the anticyclone could bring a few mid and high clouds at times this weekend, but expect mainly sunny skies to prevail. The models are suggesting a weak disturbance could set up just off the central CA coast on Wednesday and may linger through the end of the week. We could begin to see some afternoon cumulus development over the Sierra Nevada Wednesday, but no thunderstorms are forecast at this time.

AVIATION. VFR conditions will prevail over the central California interior for at least the next 24 hours.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
