Area Forecast Discussion National Weather Service Hanford CA 940 AM PDT Wed May 13 2026
KEY MESSAGES
1. Lake Wind Advisory remains in effect until 8 pm Wednesday for the Kern River Valley.
2. Practice safety around area lakes, rivers, and streams as waters are still running cold.
3. A warming and drying trend the next few days.
4. Increasing fire risk as the weekend approaches.
DISCUSSION
A trough moving through the Pacific Northwest will bring some relief from the extreme heat, with highs across the Valley in the lows 80s to near 90 Wednesday. As the trough clears the area, temperatures will warm a bit, with highs expected in the high 80s to mid 90s across the Valley by Friday. Conditions will stay dry during this period, though a stray lightning strike in the Sierra Nevada cannot be ruled out (5-10% probability each day).
As another trough passes through the Pacific Northwest this weekend, the area will see another minor cooldown, though a ridge will begin to build back into the area after that, with a 10-25% chance of triple-digit temperatures in the Valley on Tuesday, increasing to 15-40% on Wednesday. Relative humidity values will be on an overall decreasing trend over most of the next seven days, and this, in tandem with increasing temperatures and periods of windy conditions, will create elevated fire concerns beginning Friday. Rivers, lakes, and streams are all still quite cold; practicing water safety is paramount.
