Area Forecast Discussion National Weather Service Hanford CA 248 AM PDT Fri Sep 13 2019 .SYNOPSIS... A warming trend will continue into the weekend. High temperatures Friday and Saturday will be well above normal. Cooler and breezy conditions will return early next week with higher elevation precipitation possible and temperatures well below normal. && .DISCUSSION... Flat ridge of high pressure in the upper levels is allowing temepratures to continue to rise today and Saturday. Most areas in the SJV will be in the upper 90s with a few locations near the major metropolitan areas reaching triple digits due to the heat island effect. The normal high temperatures for this time of year are in the lower 90s, so we will be experiencing above normal values today and Saturday with Saturday being the hottest day. A very impressive cold fall-like trough will dig south in the EPAC by Sunday into NORCAL from the Gulf of Alaska. The system is moisture starved and will bring light precipitation to the higher elevations of the Sierra with a few showers possible mainly north of Tulare County Monday night and Tuesday morning. Snow levels will start out around 9500 feet and lower to around 8500 feet before ending Tuesday morning. A light dusting to up to around 2 inches is possible above 9000 feet in Yosemite NP. Light rain is possible in the SJV...mainly north of Fresno County. Trace amounts are expected in the SJV with up to 0.05 in the foothills. Eventhough this system is relatively dry, we will see a significant temperature change Monday and continue through the week next week. This will be our first taste of Fall as Temperatuers will drop some 8-15 degrees below normal for this time of year, with the coolest day being on Tuesday. Post frontal environment will be windy with strong gusty winds expected in Kern county and the Sierra high country on Tuesday. A secondary low pressure system will move into the PACNW on Wednesday and we can see continued unseasonably cool weather Wednesday and Thursday with clear skies and morning lows in the mid 50s in the SJV and around freezing above 8000 feet in the Sierra. After a long Summer, I am really looking forward to next weeks weather.Source: NWS
