Area Forecast Discussion National Weather Service Hanford CA 242 AM PDT Sun Jun 9 2019 .SYNOPSIS... A significant warming trend will continue this weekend into early next week. This warming trend will peak Tuesday afternoon, then temperatures should slowly decrease during the remainder of next week. 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 build to the northwest across Central California today. As a result, high temperatures this afternoon will be around ten degrees warmer than yesterday afternoon. Maximum temperatures this afternoon will be five to ten degrees above normal for this time of year. The ridge of high pressure over the Desert Southwest will amplify over the Golden State tonight through Tuesday, reaching its peak strength Tuesday afternoon. This will coincide with the hottest day this week. High temperatures Tuesday afternoon will be near 105 degrees. Maximum temperatures Tuesday afternoon in Fresno and Bakersfield will be two to four degrees below their daily records for maximum temperatures ever observed in those locations on June 11th. An Excessive Heat Warning is in effect for the San Joaquin Valley and west side hills Monday afternoon through Tuesday evening. Plan accordingly for these dangerously hot temperatures. The aforementioned ridge of high pressure over California will translate eastward into the Great Basin Wednesday and Wednesday night. This will result in high temperatures Wednesday afternoon to not be as hot as Tuesday afternoon. Be that as it may, maximum temperatures Wednesday afternoon will be around ten degrees above their typical values for the middle of June. Zonal flow aloft will prevail Thursday into the upcoming weekend. A couple of subtle atmospheric disturbances aloft will likely pass over California embedded in the swift, upper-level flow. 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.
