textproduct: San Joaquin Valley
This forecast discussion was created in the public domain by the National Weather Service. It can be found in its original form here.
KEY MESSAGES
1. Freezing overnight low temperatures for a portion of the San Joaquin Valley tonight into Saturday.
2. Stronger wind gusts continue over the Mojave Desert and Sierra Nevada crest until Saturday.
3. Areas of dense fog return to the San Joaquin Valley later this weekend into next week.
DISCUSSION
Clear skies helped bring overnight lows last night to around freezing and brought temperatures back up. However, there is a 20 to 30 percent chance of freezing temperatures in the Valley overnight tonight into Saturday morning. Luckily, the potential for dense fog continues to remain low thanks to much drier conditions during the day as there is a 20 to 40 percent chance of visibilities of quarter mile or less in places like Hanford and Visalia and not widespread.
Temperatures will continue to climb through the weekend into next week thanks to the ridge as it builds. There is a 60 to 90 percent chance of high temperatures of at least 60 degrees in the Valley from Fresno and points south Thursday and Friday. This warming and dry pattern looks to continue as the latest CPC outlooks have very strong 50 to 80 percent chances of above average temperatures and a 40 to 60 percent chance of below average precipitation.
AVIATION
VFR conditions will prevail for the San Joaquin Valley, with a 30 to 50 percent chance of MVFR after 9Z Saturday, with a 20-40% chance for IFR to LIFR conditions for Hanford and Visalia from 12Z through 18Z Saturday. VFR conditions will prevail for the next 24 hours for the Mojave Desert.
