969 FXUS66 KHNX 200032 AFDHNX Area Forecast Discussion National Weather Service Hanford CA 430 PM PST Thu Nov 19 2020 ...UPDATED AIR QUALITY SECTION... .SYNOPSIS... Cool, near seasonal highs are expected to occur for the next seven days. A disturbance will pass through the area on Monday, which could provide the Sierra Nevada with a slight chance of precipitation. Otherwise, expect the rest of Central California to remain dry for the next seven days. && .DISCUSSION... Some patchy fog formed earlier this morning in the valley portion of Kern County, and mixed out by late morning. In the northern portion of the San Joaquin Valley, a stream of high clouds is currently passing through and will continue to do so for the rest of the day, eventually getting the central and south valley tonight. In terms of fog tonight, the latest HRRR isn't showing much fog -- perhaps the incoming upper cloud cover will help avoid a fog event. Anyways, expect near normal temperatures today, meaning highs in the mid 60s. Afternoon highs are expected to drop in the low 60s as a couple of embedded disturbances pass through the region this weekend. Highs in the low 60s are a couple degrees below average. Morning lows by Saturday will be on the cool side, likely in the low to mid 30s. By late Sunday/early Monday, an upper level low will approach the forecast area. This low is likely to be moisture-starved, but could trigger a shower or two over the Sierra Nevada by Monday afternoon. Weak upper ridging is forecast by Tuesday and Wednesday, but it won't be enough to move the temperature forecast much. Expect low 60s for afternoon highs to continue next week, including Thanksgiving Day. Dry weather is likely to continue for most of the forecast area in the foreseeable future. && .AVIATION... MVFR visibility due to mist is possible in San Joaquin Valley from 08z Friday to 16z Friday. Otherwise, VFR conditions will prevail for the next 24 ours across the Central California Interior. && .AIR QUALITY ISSUES...
