Area Forecast Discussion National Weather Service Hanford CA 355 AM PDT Sun Apr 10 2022 .SYNOPSIS... High temperatures will continue to drop and be around ten degrees below normal for this time of year by Monday. Precipitation and strong winds are possible ahead of and along a cold front Monday afternoon into early Tuesday. && .DISCUSSION... The passage of a dry cold front on Saturday ushered in a change in Central Californias weather. The strong winds of the Spring season are in full force as the winds blew on Saturday. Observed wind gusts were able to reach 20 to 30 mph as the cold front sweep across the region. Along with the strong winds, the cold front did manage to push out the strong ridge pattern that had been over the West Coast for several days. After several days of having temperatures reach into the 90s, the San Joaquin Valley barely reached the 80 degree mark on Saturday. Central California will remain under a cyclonic flow pattern for several days as temperatures continue a downward trend as a storm approaches the district this week. Unsettled weather conditions are expected across the Central California Interior as rain, snow and strong winds return once again. Ensemble are still calling for a possible winter-like storm early this week. Confidence is high in the break down of the ridge pattern as a rather cold disturbance moves through the region. Temperatures have started a down turn to more seasonal normal values. Ensemble are struggling to see temperatures exceeding 90 degrees by Sunday afternoon. This low value in the probability of exceedance for near 90s will increase confidence in much cooler conditions at the start of next week. Observed surface pressure analysis is currently showing the gradient from KSFO to KLAS dropping below 10mb. Will expect the gradient to drop further as wind speeds continue to lower this morning. While temperatures will remain cooler this week, winds will see another rise as it accompanies a winter-like storm on Monday and Tuesday. Ensemble upper air analysis is still indicating very cold air surging into Central California on Monday and into Tuesday. Along with a possible storm that may drop into the district from along the coast, ensembles indicate more snow for the Sierra Nevada by Tuesday. Some uncertainty exist with the timing of the disturbance as its instability may remain too far north for any convective activity on Monday. Ensembles do show some weak cape extending into the northern portions of the district (Merced Co., Mariposa Co. and Yosemite NP) late Monday, yet, convective showers are possible. Based on snow amounts, weak cape may add extra support for the Weather Weather Advisory currently in effect for the Sierra Nevada. While minor compared to previous storms, any precipitation will help Central California. In addition to the continued indication of possible precipitation, ensemble also continue to indicate very low snow levels with this next storm. Confidence is growing that some foothill locations could see a dusting of snow with the storm. Afterward, ensemble show dry conditions ahead of another possible storm around the Friday time frame. Hopefully, ensembles will on to this next possible storm for additional precipitation. && .AVIATION... VFR conditions will prevail across Central California through at least the next 12 hours. Precipitation will return to Central California Monday morning as MVFR and strong winds enter the area. && .AIR QUALITY ISSUES... None.Source: NWS
