Area Forecast Discussion National Weather Service Hanford CA 117 AM PDT Wed May 27 2020

SYNOPSIS. Heat wave intensifies today as afternoon high temperatures soar 17-20 degrees above average across Central California. Excessive heat continues tomorrow as upper level ridging persists. Cooling trend to begin Friday as an upper low nears the region, also leading to breezy conditions in the wind-prone areas of the forecast area. Cooler and a slight chance of showers early next week as a trough impacts the district.

DISCUSSION. Hot weather to persist today as the ridge axis shifts east, leading to additional height rises/thickness increases over the forecast area. Afternoon highs yesterday were in the 100-104 degree range, and expect a few degrees warmer today. This will put most of the San Joaquin Valley in the 103-107 degree range today, or 17-20 degrees above normal for late May. Ridge axis hedges slightly eastward tomorrow, but builds a few decameters, so expect afternoon highs to remain hot again for tomorrow, with many areas expected to hit 105-107 degrees in the SJ Valley. Near Indian Wells Valley, expect highs today to reach 104-107 degrees, and up to 106-109 degrees tomorrow. Starting at 11 AM today, the Excessive Heat Warning will include the entire desert portion of Kern County, and will remain valid until 7 PM Thursday; see the Excessive Heat Warning for more details. With the excessive heat impacting the region, we want to remind everybody that while area rivers may look like an inviting place to cool off, they present a major hazard to those who enter. Rapid onset of hypothermia may occur to those who venture into very cold rivers seeking heat relief. River currents are also running swift as additional snowmelt occurs this week. This combination of hazards can make local rivers dangerous to enter and can result in swift water rescues or even a cold water drowning.

Change in the pattern as an upper level disturbance nears the forecast area Friday. Upper height falls to occur as the ridge shifts eastward, heralding the start of a cooldown; afternoon highs will still be warm, near 100 degrees across the valley. Gusty winds can be expected along the west side hills and valley Friday evening as onshore flow increases, with strong winds also possible in the Mojave Desert by Friday night. A wind advisory may be required for these area once more hi-res model guidance is available. Additional cooling to continue Saturday as the upper low passes through the region, leading to near seasonal highs. Mostly a cooler and cloudier pattern to continue through the weekend as medium range guidance suggests a trough pattern aloft over the CWA, with a slight chance of light showers across most of the forecast area Monday and Tuesday afternoon.

AVIATION. VFR conditions will prevail across the interior of Central California through 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.
