Area Forecast Discussion National Weather Service Hanford CA 349 AM PDT Wed Mar 25 2020 .SYNOPSIS...Another storm system will bring more wet weather to the region through Thursday. Dry weather is expected Friday through the weekend, except for a slight chance of showers on Saturday for mainly the northern portions. Temperatures will be several degrees below normal through Friday then warming up to near normal this weekend. && .DISCUSSION... A digging cold trough of low pressure has pushed a surface cold front through the region. Precipitation has been generally light across the CENCAL interior. Cyclonic flow across the region will keep the chances of showers today and tomorrow. Scattered thunderstorms are expected today as an upper level impulse moves through the region. Small hail, locally heavy rain and possible cold air funnel clouds will be the threat today. Snow levels will drop very quickly as the colder air moves in. There is limited moisture with the system and unfortunately we will not see heavy snow amounts, even in the higher elevations. We have a winter weather advisory in effect for the Sierra. With cold air moving in over the area tonight we will see lows in the mid to upper 30s tonight and tomorrow night in the SJV. Showers will once again develop on Thursday as the upper trough kicks east. Weak ridging is expected for Friday with dry conditions. Models are still not in agreement with the strength of another trough forecast to move into the region on Sunday. Forecast confidence is low for the extended period with this system. The system will move east and the EPAC ridge will build in over the area with a warming trend in store early next week with significantly above normal temperatures.Source: NWS
