Area Forecast Discussion National Weather Service Hanford CA 213 PM PDT Fri Jul 3 2020

SYNOPSIS. Dry weather will continue over the district for the next several days. A slight warm up will occur this weekend. Temperatures will lower to seasonable levels again early next week and change little through Thursday.

DISCUSSION. The weather across the central California interior this afternoon is almost an exact duplicate of yesterday with sunny skies and little change in temperatures. Since the beginning of this week, California has been situated between an upper level Low near Vancouver and an upper level ridge of high pressure over Texas. During the next 72 hours, that ridge will retrograde. It will be centered well off the coast of northern Baja by late Monday. It's westward migration will bring slightly warmer weather into the central California interior this weekend, but nothing too extreme. High temperatures Saturday and Sunday will probably reach the century mark in the hottest locales of the San Joaquin Valley and lower foothills and peak a few degrees above 100 in a few desert locations. Nighttime low temperatures will be a tad higher this weekend, too.

Once the high pressure ridge positions itself off the coast of northern Baja, it will make room for an upper level trough to settle southward into California early next week. In doing so, the marine layer will likely deepen along the central California coast and a modest onshore flow will become reestablished over the CWA and bring a slightly cooler airmass inland. Temperatures should trend back to normal again by Tuesday. Shallow troughiness will linger over California through at least Thursday with little day to day change in temperatures.

During the latter part of next week, the models build a strong (60 decameter) ridge of high pressure over the Four Corners region. This is a region that high pressure ridges like to anchor anchor themselves every Summer and are often difficult to dislodge. This will likely happen by the end of next week. As this high pressure ridge expands westward, it may bring a return of widespread triple digit heat to the San Joaquin Valley, lower foothills and the Kern county desert. If the ECM is right which is aggressively building this ridge westward into California in the 7 to 10 day period, widespread triple digit temperatures could materialize as early as next Friday. Once here, we could be in for a rather lengthy spell of 100-degree heat. During this time, the monsoon will be flaring up over the Desert Southwest. This is about the time of year we begin to monitor the monsoon. At some point, perhaps by mid July, some of this moisture may creep into our mountains and desert, but probably not before then.

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

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
