Area Forecast Discussion National Weather Service Hanford CA 330 AM PDT Sat Aug 17 2019 .SYNOPSIS...Dry weather can be expected over the central California interior for the next several days. Temperatures will cool to near normal by Sunday and Monday. Hot weather will return during the mid to later part of next week with highs above 100 degrees in the San Joaquin Valley, lower foothills and the Kern county desert. && .DISCUSSION...The stage is set for a significant cooling trend over the central California interior during the next few days. As of this writing, temperatures are already trending 3 to as much as 15 degrees lower than 24 hours ago over the northern half of the state. Brisk winds are blowing through the Sacramento Delta this morning and gusting as high as 30 mph at Travis AFB. The marine layer along the central California coast is deepening as of this writing and time lapse satellite imagery shows the inland invasion of low stratus into the coastal valleys. These are excellent indicators of a definitively cool change in the weather across the entire CWA during the next 24 to 48 hours. We can credit this cooling to an upper level trough over the Pacific Northwest. The trough will settle southward into the Golden State this weekend and finally shove the high pressure ridge that`s been baking us into Texas. Although cooler air will be infiltrating our CWA today, high temperatures will still top the century mark over the southern half of the San Joaquin Valley, the lower foothills of Tulare County and the Kern county desert but it will be the last day of triple digit heat in any part of our CWA until the middle of next week. Sorry about that spoiler. Yes, 100-degree heat will indeed make its return by Wednesday or Thursday in the San Joaquin Valley, lower foothills and the Kern county desert, so enjoy the short-lived cool down. Sunday and Monday will be the coolest days in this pattern with highs in the upper 80s to lower 90s in the San Joaquin Valley. Minimum temperatures in the valley will be very comfortable during this period with lows ranging from the mid 50s to mid 60s. In the Kern county desert, afternoon high temperatures will stay below the century mark Sunday and Monday with lows generally in the 60s. Additionally, the cool change will be accompanied by gusty west to northwest winds this weekend. Gusts of up to 35 mph are likely through and below the passes on the west side of the San Joaquin Valley this afternoon and evening with a possible recurrence late Sunday into Sunday night. The winds could also kick up some dust in a few locations west of Interstate 5. In the Kern County mountains and desert, westerly winds could gust to 40 mph or higher through and below the passes this weekend. The onshore flow will dwindle Monday and become offshore again by Monday night or Tuesday as the high pressure ridge over Texas begins to builds westward. As the ridge retrogrades next week, it will inevitably put us back in the frying pan. As we`ve already indicated, widespread triple digit heat will return to elevations at and below 2500 feet by Thursday. The pattern will likely stagnate across central California in the 5 to 7 day period as the high pressure ridge remains in control. During that time, the models forecast an increase in activity over the tropical regions of the eastern Pacific with the possibility of a named cyclone near the Baja peninsula. Whether or not tropical moisture from this system moves northward into California by next weekend is questionable, but it`s worth watching. Otherwise, it appears that the high pressure ridge over the southwestern U.S. will keep central California dry in the extended forecast period.Source: NWS
