Gusty northwest winds are likely through and below the mountain passes west of I-5 and on the west side of the San Joaquin Valley this afternoon and evening. Travel will be difficult, particularly for high profile vehicles, such as campers and tractor trailers. Highways affected include, but are not limited to Highway 33, Highway 152 through Pacheco Pass, Interstate 5 north of Coalinga, and Highway 198 west of Interstate 5. Here are peak wind gusts we are expecting through this evening.
Maximum temperatures throughout Central California this afternoon will be about five degrees lower than yesterday. Maximum temperatures across Central California Wednesday afternoon will be around five degrees lower than Tuesday afternoon. Be that as it may, high temperatures throughout Central California Wednesday afternoon will be a couple of degrees above normal for this time of year.
A few strong thunderstorms are possible in the Sierra Nevada from Sequoia National Park northward Wednesday afternoon into Wednesday evening. Small hail and wind gusts near 45 miles per hour are a couple of hazards associated with strong thunderstorms. In addition to dangerous cloud to ground lightning strikes, any thunderstorm can produce intense rainfall rates, leading to localized flooding.
