Area Forecast Discussion National Weather Service Hanford CA 303 AM PDT Mon Jun 10 2019 .SYNOPSIS... Dangerously hot temperatures are expected this afternoon and Tuesday afternoon in the San Joaquin Valley and west side hills. Triple digit high temperatures are likely Wednesday afternoon in the San Joaquin Valley and west side hills, before temperatures slowly decrease Thursday into the upcoming weekend. Dry weather will prevail throughout Central California for at least the next several days. && .DISCUSSION... A ridge of high pressure over the Desert Southwest will amplify over Central California today and tonight. As a result, high temperatures this afternoon in the San Joaquin Valley and west side hills will be in the lower 100s. This ridge of high pressure will reach its peak strength Tuesday afternoon. This will coincide with the hottest day this week. Maximum temperatures Tuesday afternoon in the San Joaquin Valley and west side hills will be near 105 degrees. High temperatures Tuesday afternoon in Fresno and Bakersfield will be three to four degrees below their daily records for maximum temperatures ever observed in those locations on June 11th. As a result of these dangerously hot temperatures, an Extreme Heat Warning is in effect for the San Joaquin Valley and west side hills this afternoon through Tuesday evening. The aforementioned ridge of high pressure over California will translate eastward into the Great Basin Wednesday and Wednesday night. High temperatures Wednesday afternoon will not be as hot as Tuesday afternoon. Be that as it may, maximum temperatures Wednesday afternoon will be around ten degrees above normal for the middle of June, which would be near 100 degrees in the San Joaquin Valley and west side hills. A Heat Advisory may be required for the San Joaquin Valley and west side hills Wednesday afternoon and Wednesday evening. Zonal flow aloft will prevail Thursday through at least Friday, resulting in a decreasing temperature trend. A Wind Advisory may be required for the Kern County mountains and desert Thursday afternoon into Thursday night. A couple of subtle atmospheric disturbances aloft may pass over California next weekend. These impulses should destabilize the atmosphere somewhat. There may be enough of an increase in moisture for a few showers to develop over the higher terrain of the Southern Sierra Nevada next weekend. Don`t hold your breath though as the month of June is typically a dry month throughout Central California.Source: NWS
