Area Forecast Discussion National Weather Service Hanford CA 1237 PM PDT Mon Apr 15 2024



KEY MESSAGES
1. Below normal temperatures prevail today before rebounding next week.

2. A significant warming trend is forecast through Thursday as high pressure builds.

3. Afternoon highs are forecast to remain steady through the weekend.

4. The warming trend will not cause hydrological concerns due to snowmelt in the Sierra Nevada this week.

DISCUSSION
The upper low that brought widespread precipitation over Central California last weekend is finally exiting the region today.
This is why we are still dealing with low level cloud cover and cooler temperatures. However, the airmass is forecast to modify dramatically over the next few days. Afternoon highs today remain well below normal, but this will not last tomorrow as the ridge of high pressure builds in across the Golden State.
Highs are forecast to jump nearly 10 degrees tomorrow vs today's highs, and then rise several more degrees Wednesday through Thursday. By Thursday, afternoon highs are projected to be as much as 10 to 15 degrees above normal. Afternoon highs Friday through Sunday are forecast to moderate slightly as a pair of upper lows flatten the ridge over the west coast.

Run-off from the snowpack is not forecast to be much of an issue at this time either. Afternoon highs in the valley usually need to be in the 90's for several days to see hydrological concerns develop from a melting snowpack, and this forecast is not calling for that. This ridge pattern is forecast to be dry through the next 7 days for the entire forecast area. Anyways, as it pertains to the heat on Thursday, here are probabilities for afternoon highs reaching or exceeding 85*F for select locations across the San Joaquin Valley:

Merced: 21% Madera: 21% Fresno: 71% Reedley: 16% Lemoore: 56% Hanford: 51% Visalia: 61% Porterville: 26% Delano: 46% Bakersfield: 41%
