UPDATE. Updated POPs, sky, and weather for the mountain areas through early this evening. Also updated air quality issues section.

SYNOPSIS. Hot afternoon highs the next couple of days with a chance of afternoon thunderstorms over the Sierra Nevada crests each day. Rollercoaster temperature pattern Friday through the rest of the forecast period as a significant cooling trend occurs this weekend followed by a rebound in high temperatures next week.

DISCUSSION. Updated sky cover, as well as chances of showers/thunderstorms through early this evening, or around sunset and winds through Thursday evening. Based on latest data, including radar and high resolution models, showers and isolated thunderstorms could develop just about anywhere over the Kern County mountains northward to the Sierra Nevada, including Yosemite.

PREV DISCUSSION. /issued 112 PM PDT Wed Jun 3 2020/

DISCUSSION. Afternoon high temperatures are expected to surge today as upper level heights increase as a ridge of high pressure builds west. Latest GOES satellite imagery reveals mostly clear skies over the valley that will aid in solar heating, so expect widespread afternoon highs today to top the century mark, with some of the lower elevations hitting up to 103-104 degrees. With the increase in afternoon highs, a Heat Advisory will take effect at 2 PM this afternoon and will continue through 7 PM Thursday. Bubbling cu present over the Tulare County Mountains currently, which may be represent the greatest chance for afternoon thunderstorms as instability increases over the Sierra Nevada. Similar pattern to be expected tomorrow, except a few degrees warmer. Afternoon highs are forecast to generally range from 103 to 106 degrees across the valley, with a slight chance of showers and thunderstorms over the high Sierra by afternoon.

Upper low that has been meandering off the coast is forecast to move inland by late Friday. This should knock down afternoon highs 10-15 degrees as upper heights fall, cloud cover increases, and onshore flow occurs. Breezy to gusty conditions can be expected by Friday afternoon along the West Side Hills and through the Mojave Desert. Finally, a few afternoon thunderstorms are possible by afternoon along the Sierra Nevada and Tehachapi Mountains as the cold front pushes through. Cooling trend, breezy conditions through the wind prone areas, and slight chance of showers and thunderstorms along the Sierra Crests look conceivable Saturday. Blended model guidance pegs Sunday to be the coolest day of the cooling trend with afternoon max temps only in the mid 70s across the San Joaquin Valley, which would be about 15 degrees below average for early June.

Decent model agreement in that the trough pattern that will impact Central California will give way to another ridge of high pressure starting early next week. This will likely lead to another warming trend across the forecast area, with afternoon highs next week getting hot into the mid 90s by next Wednesday.

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.
