May 5, 2022 - The National Weather Service Hanford Office reports maximum temperatures throughout Central California Friday afternoon will be three to five degrees lower than this afternoon.
High temperatures across Central California Saturday afternoon will be about five degrees cooler than Friday afternoon.
By Sunday afternoon, maximum temperatures throughout Central California will be around ten degrees below normal for this time of year.
Area Forecast Discussion National Weather Service Hanford CA 300 AM PDT Thu May 5 2022 .SYNOPSIS... Temperatures will remain above normal through Friday. A cooling trend will then take place with temperatures lowering to near normal by Saturday and then below normal through the middle of next week. Gusty winds are possible over the weekend and light precipitation is possible in the Sierra Nevada by Monday. && .DISCUSSION... Upper ridge pattern will dominate the West Coast for one more day as warm temperatures will be observed this afternoon. The San Joaquin Valley was able to reach the 90 degree mark on Wednesday as the ridge axis was overhead. While upper air analysis is showing the ridge axis slowly shifting east today, enough lingering heat will allow for one more day of well above normal temperatures. Yet, probability of exceedance for 90 degree over above temperatures is only reach the 50 to 60 percent mark for areas from Fresno County southward. Therefore, areas in Merced and possibly Madera Counties may struggle to reach the 90 degree mark today. As for winds, under a ridge, surface pressure gradients remain at relax values and have been bouncing around 1mb to 2mb on Wednesday and overnight. Breezy winds could develop over portions of Kern County, yet, remain below advisory criteria. A disturbance is poised to push across the Pacific Northwest today and introduce the Central California Interior to strong westerlies. While this pattern will affect Central Californias temperatures, uncertainty exist on any potential precipitation event reaching the district. Hi-Res ensemble mean upper air analysis is in good agreement with the expected pattern development of having a disturbance cross the Pacific Northwest. Main impact over Central California will be a return to cooler conditions as the passage of the disturbance introduces a zonal flow pattern across the region. While Hi-Res ensemble shows some strong winds spreading into the northern portions of the Central California, will not expect the strong winds to reach down into Kern County. Yet, breezy winds may develop today over the higher terrain as even the Kern County Mountains could see 15 to 25 mph gusts this afternoon. However, the lack of surface support due to a weak surface pressure gradient may keep the stronger winds over the mountains and reduce the threat of advisory level winds. Ensemble solution then shows minimal change going into Friday. Saturday will see significant change in the forecast as a piece of energy digs deeper in to California and introduces much colder air into the region. However, the colder air will only lower temperatures back to near normal values. Further out in the forecast range, ensemble clustering analysis shows a signal toward a disturbance digging through the region early next week. While the signal does lean in the direction of significant cold air reaching the district, will lean toward the mean value range. Therefore, colder than normal along with precipitation possibilities around the Monday and Tuesday period. Yet, based on cluster precip accumulation analysis, will confine the precipitation to mountainous areas and other areas show very minimal chances of precipitation. Uncertainty in a possible solution for Wednesday is high, yet, may see lingering effects of the earlier storm. && .AVIATION... VFR conditions will prevail throughout the Central CA Interior for at least the next 24 hours. && .AIR QUALITY ISSUES... None.Source: NWS
