Area Forecast Discussion National Weather Service Hanford CA 212 AM PST Sat Feb 26 2022 .SYNOPSIS...Widespread freezing temperatures will occur again in the San Joaquin Valley this morning. A slow warmup begins by Sunday as temperatures gradually increase back to seasonably normal values the to above normal levels for Monday through Wednesday. A weak system will bring cooler temperatures along with a chance for precipitation to much of the area on Thursday. && .DISCUSSION...Northerly flow aloft continues over our area as we are currently situated in between an upper ridge just off the CA coast and a trough over the Great Basin. With clear skies and light surface winds prevailing over our area once again radiational cooling will provide for another frosty morning across the San Joaquin Valley although temperatures are currently running 1-3 Deg F above yday at this time. This should be the last night with widespread sub-freezing temepratures in the San Joaquin Valley as SREF is indicating the offshore ridge builds inland today resulting in rises in heights and thicknesses, and a storm riding over the ridge pushes into the PAC NW tonight and Sunday spreading mid/high clouds into our area which will partially limit radiational cooling. Latest NBM probabilistic guidance indicates the chance of subfreezing temperatures in most of the San Joaquin Valley on Sunday morning is 2 percent or less. With the ridge shifting inland on Sunday, a southwest flow aloft will become established over central CA. This will result in a warming trend over our area Sunday through Wednesday with daytime temperatures rising to slightly above seasonal normals on Sunday trending upward each day through Wednesday. Dry weather will prevail across our area through Wednesday although storms moving through the PAC NW will bring some mid/high clouds to our area. The medium range ensemble means are trending a further northward track with a system which might impact our area on Wednesday night and Thursday. There is still some spread amongst the ensemble members with this system, but the latest NBM probabilistic guidance is now indicating just a 25 percent chance of measurable precipitation for Yosemite Valley on Thursday with most of the San Joaquin valley north of Kern County having a 15 to 20 percent chance of measurable rain on Thursday. Guidance is continuing to show that temperatures are progged to cool to near seasonal normals for Thursday and Friday. && .AVIATION...VFR conditions will prevail throughout the Central CA interior for the next 24 hours. && .AIR QUALITY ISSUES...On Saturday February 26 2022... Fireplace/Wood Stove Burning Status is: No Burning Unless Registered in Fresno... Kern... Kings... Madera and Tulare Counties. Further information is available at Valleyair.orgSource: NWS
