Area Forecast Discussion National Weather Service Hanford CA 104 AM PST Tue Nov 28 2023


SYNOPSIS
Near freezing overnight low temperatures through Wednesday morning.
Freeze Warning in effect until Wednesday morning. Rain and snow chances increase on Wednesday. Best chance for rain will be Thursday night into Friday with a 20 to 30 percent chance of a tenth of an inch of rain in the Valley. Snow levels expected to drop to about 4,000 feet Thursday night into Friday morning. Temperatures warm up on Sunday into early next week.

DISCUSSION

Currently we have a ridge of high pressure over the Pacific Northwest which has been bringing in a steady northerly flow of cold air into our area. This setup has helped bring overnight lows to near or below freezing the past few nights. However, model ensembles are in strong agreement that the ridge will weaken today and move east. The ensembles show a trough sliding into our area throughout the day Wednesday. This trough is bringing with it a 10 to 20 percent chance of at least 0.05 inches of rain to most of the San Joaquin Valley.

The ensembles are showing a second trough moving in late Thursday into Friday. This second trough will bring a 20 to 30 percent chance of at least a tenth of an inch of rain from 4 PM Thursday to 4 PM Friday. There is a 40 to 60 percent chance of at least 2 inches of snow in the Sierra Nevada with this second trough with the higher probabilities more near Yosemite. Snow levels drop to 4000 feet during this second trough. HIgh temperatures will also continue to drop below average.

After the second trough moves out on Saturday, a ridge of high pressure will develop over the Pacific Coast on Sunday into early next week. This new ridge will bring temperatures to average for early December.

Here are the probabilities of high temperatures of at least 60 degrees on Friday, December 1, 2023:

Fresno-11% Bakersfield-11% Lemoore-51% Merced-21% Reedley-11% Delano-16% Hanford-26% Madera-31% Porterville-6% Visalia-11%

KEY POINTS: * Freeze Warning in effect until 8 AM Wednesday.
* Latest NBM probabilities have a 20 to 30 percent chance of at least 0.10 inches of rain from 4 PM Thursday to 4 PM Friday.
