A Possibility of Thunderstorms for Mariposa and Oakhurst TodayDecember 8, 2019 - The National Weahter Service Hanford Office reports we are expecting some isolated thunderstorms over the area later today.
Here is the outlook area from the Storm Prediction Center showing areas where thunder is possible.
Area Forecast Discussion National Weather Service Hanford CA 156 AM PST Sun Dec 8 2019 .SYNOPSIS... A weather system will affect the district through this evening. A ridge of high pressure will build into the area for Monday and Tuesday, with morning fog possible. Quick, mainly dry short wave moves through Central California on Wednesday, before ridge builds across the area into the end of next week. && .DISCUSSION... Radar shows the main area of precipitation from the latest short wave now pushing across Fresno, Kings and Tulare counties as the wave moves east to southeast across the Central California Interior. High resolution short range models continue to drive this precipitation band to the southeast overnight with the bulk of it reaching Bakersfield and the Kern County Mountains after 7 AM. As the center of the low pressure system moves southeast across the forecast area today...a showery pattern will persist with cold air aloft providing enough instability for a few low topped thunderstorms over mainly the San Joaquin Valley and foothills this afternoon. There should be enough coverage of these developing and passing showers to keep chances of precipitation moderate all day however it certainly will not be a constant rain or snow event in the Sierra. As for continued snow threat in the Sierra, model projected precipitation suggests several inches or more of snow will fall above 6000 feet today thus the winter storm warning will remain in place through early evening. By later this afternoon and early evening...models move the low pressure trough southward into Southern California and this will effectively end the precipitation for Central California. On Monday, a sharp ridge of high pressure is progged to build down the West Coast with the ridge holding into Tuesday. This scenario will provide dry and warming weather for all areas outside the San Joaquin Valley where...you guessed it...patchy fog will form Monday morning with the threat of widespread fog Tuesday morning. Should see lower level inversion conditions increase during this time frame and afternoons will become more hazy in the lower elevations. Models then bring a weak short wave trough into the ridge on Tuesday night and Wednesday and some light precipitation may reach into the Yosemite area but little chance will exist to the south. The pattern looks to remain dry beyond Wednesday as the storm track is pushed well to the north due to strengthening high pressure west of Baja and Southern California later in the week. Looks like the ridge will keep things dry well into next weekend with again, mainly clear and warming weather for everyone outside the SJV where fog, low clouds and cool temperatures are a frequent product of this synoptic pattern in mid December.Source: NWS
