Area Forecast Discussion National Weather Service Hanford CA 543 PM PDT Mon Aug 3 2020

. UPDATED AIR QUALITY SECTION .

SYNOPSIS. High pressure will give way to an approaching trough of low pressure and a secondary low pressure system. Winds will be gusty tonight and Tuesday and temperatures will have a robust cool down through Thursday. Later this week and this weekend, a warming trend will begin with the weather remaining dry.

DISCUSSION. Ridge of high pressure continues to flex its muscle with the center of the anticyclone over the lower Colorado River Valley. As a result, temperatures over the forecast area show little change from yesterday. Upstream, a dry trough of low pressure is noted on water vapor imagery making inroads into Northern California and this is the harbinger of the cooler and refreshing weather pattern that is knocking at the Central California Interior's door.

As is the case in all weather pattern changes, winds will become frisky this evening and overnight and will linger through the passes and canyons Tuesday. Temperatures on Tuesday will be markedly cooler over especially Merced County as the onshore flow and lowering heights aloft will keep highs into just the low 80s while over the remainder of the lower elevations a more modest cooling of just a few degrees will ensue.

On Wednesday with heights aloft falling to around 5830 meters as the trough axis swings into Central California, another retreat in highs will occur with low 80s over Merced County . around 90 in the Fresno area and lower 90s in Bakersfield. The coolest day for areas south of Fresno and over the Kern County Desert will be Thursday as the Indian Wells Valley will observe an unusual early August day below 100 degrees.

From Friday through the weekend forecast models develop and weak low pressure system along the NorCal coast however the airmass over the region will begin to moderate as heights increase. Although not a fast warm up, highs will inch up a few degrees each day from the mid week "coolness". The year of the "Nonsoon" continues with models keeping a dry westerly flow pattern into the region through the next 10 days.

AVIATION. Northwest winds gusts near 30 mph are likely in the San Joaquin Valley late this afternoon and this evening. West to northwest wind gusts as high as 55 mph are probable through and below mountain passes in Kern County today and tonight. Otherwise, VFR conditions will prevail at MCE, MER, FAT, VIS, and BFL through at least then next 24 hours.

AIR QUALITY ISSUES. On Tuesday August 4 2020 . Unhealthy for sensitive groups in Sequoia National Park and Forest. Further information is available at Valleyair.org

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.
