Area Forecast Discussion National Weather Service Hanford CA 424 AM PDT Sat Apr 24 2021 .SYNOPSIS... A storm system will bring rain and mountain snow to the region from late tonight into Monday morning along with unseasonably cool high temperatures Sunday and Monday. Dry weather and a day to day warming trend will occur Tuesday through the end of next week. High temperatures of ninety degrees or warmer are likely in the San Joaquin Valley, lower foothills and the Kern County desert by Thursday. && .DISCUSSION... Shortwave energy pushing into northern California ahead of a northeast Pacific low pressure system is spreading mid and high cloudiness across our region while radar indicates some light precip/virga brushing by our northern sections. Temperatures are running up a couple of degrees over much of our area beneath the increased cloud cover. Tightening onshore surface pressure gradients associated with the incoming trough are producing increasing southwest to west gusty winds across the mountains and desert areas of Kern County. The shortwave trough will continue to push inland today while the northeast Pacific low pressure system swings southeastward toward the coast. Onshore pressure gradients will continue to strengthen and gusty winds will further increase, so a Wind Advisory is in effect for the Kern County desert areas beginning at noon today. Model solutions are consistent with the incoming low pressure system, bringing it ashore by early Sunday morning and swinging it inland through Monday. Showers are expected to spread southward into central California overnight and affect all of our area by Sunday. There is little change in forecast precipitation amounts, with Valley locations expected to receive around 1/10 to 1/4 of an inch, lighter on the west side. Amounts will increase in higher elevations of the Sierra, with up to 3/4 of an inch in the foothills and around 1 inch at higher elevations. Snow levels will run around 6000 ft and we can expect 6-12 inches of snowfall accumulating north of Kings Canyon, up to 18 inches at the highest elevations. A Winter Storm Warning is therefore in effect for this area 2 AM Sunday to 11 AM Monday. Snow fall amounts farther south in Tulare County will be lesser, with around 3-7 inches expected, and A Winter Weather Advisory is in effect there 5 AM Sunday to 11 AM Monday. The passing system will maintain the gusty wind pattern and the Wind Advisory for the Kern County desert will remain in effect through 6 PM Sunday. Precipitation will taper off, with just some lingering Sierra showers by Monday evening. Temperatures will also trend downward through the weekend, a couple of degrees below normal today then likely to reach around 15-20 degrees below normal on Sunday. Dry and warming conditions will follow the exiting system for early next week, with temperatures up to 4-8 degrees above normal by Wednesday. As high pressure strengthens over our area, temperatures will continue to warm into the end of the week. By Friday there is around a 65 percent probability of high temperatures into the lower 90s across the San Joaquin Valley, lower foothills and desert areas.Source: NWS
