Area Forecast Discussion National Weather Service Sacramento CA 200 AM PDT Sat Jun 1 2024

SYNOPSIS
Slight cooldown Saturday through Monday before the return of 100s in the Valley Tuesday through Friday. An Excessive Heat Watch has been issued for the Valley from Tuesday morning until Thursday evening. Hottest temperatures expected Wednesday. Slight chance of showers for the Coastal Range Monday late morning.

DISCUSSION

Discussion at a Glance - Cooler Saturday-Monday with increased onshore flow and Delta Breeze.
- An Excessive Heat Watch has been issued from Tuesday morning to Thursday evening across the Sacramento Valley and adjacent foothills.
- Areas of Major HeatRisk Tuesday for the Valley, becoming widespread Wednesday & Thursday for the Valley & Foothills with widespread triple digit high temperatures. Prepare now for elevated daytime highs and overnight lows and reconsider outdoor activities during the hottest part of the day (3:00-7:00 PM).
- Moderate HeatRisk next Friday, with a few isolated spots of Major HeatRisk in the Valley; Triple digits in the Northern Sacramento Valley and adjacent Valley foothills with low to mid 90s in the Delta and Sacramento metro area

Short-Term Discussion

Saturday's weather looks to give a minor reprieve with temperatures 5-8 degrees cooler than Friday ahead of our impending warm up early next week. An upper level trough is sliding over Northern CA this morning apart of a larger level low moving through the Pacific NW. This will help cool the area and keep onshore flow apart of the forecast through Monday.
Afternoon highs will generally be in the upper 80s and low 90s in the Valley, with coolest temperatures expected on Monday. This weekend will be fairly quiet with generally clear skies and marginal areas of Moderate HeatRisk in the foothills and portions of the Northern Sacramento Valley. Each afternoon will see the Delta Breeze strengthen with west gusts of 15-25 MPH, tapering off through the following mornings.

As the weather system moves through the Pacific NW, it will bring general cloudiness to the area and a 20-40% chance of precipitation across the Coastal Range and Southern Cascades.
There is only a 15-25% chance of amounts over 0.10", so all indicators show that if anything were to develop it will be a minor amount of precipitation. Ultimately, it will remain over the mountains, keeping the Valley and much of the Sierra dry.
Monday will the coolest day of the 3 day stretch with Valley highs in the mid 80s with 70s and 60s across the foothills and mountains respectively.

.EXTENDED DISCUSSION (Wednesday THROUGH Saturday)...

Tuesday will see upper level ridging moving inland, increasing heights and temperatures around the region. Daytime high temperatures in the low 100s for the Valley, with widespread areas of Major HeatRisk in the Valley and extending into the foothills and portions of the Delta. National Blend of Models (NBM) probabilities of reaching 100 for the area are around 50-85% on Tuesday. Peak temperatures are expected Wednesday with the ridge firmly over the area, with hot temperatures continuing Thursday. An Excessive Heat Watch has been issued from 11 am Tuesday to 8 pm Thursday with temperatures of 95 to 107 forecasted. The Delta Breeze could bring some slightly less hot weather to influenced areas, and how strong this effect will be should become more clear over the next few days.

Major HeatRisk affects everyone without effective cooling and/or adequate hydration. Consider canceling outdoor activities during the heat of the day. Clusters show there is some uncertainty between ensembles over the strength and location of the ridge late in the week. As a result the NBM has a large spread between the 25th and the 75th percentiles, which means a large range of possible high temperatures for late in the week and into the following weekend with a 10-12 degree difference in solutions.
Currently widespread Moderate HeatRisk is expected for Friday, with isolated Major HeatRisk for the Valley/foothills.

AVIATION

VFR conditions expected over the next 24 hours. Sustained surface winds under 12 kts except winds 15 to 25kts in the Delta.

STO WATCHES/WARNINGS/ADVISORIES
Excessive Heat Watch from Tuesday morning through Thursday evening for Carquinez Strait and Delta-Central Sacramento Valley- Motherlode-Mountains Southwestern Shasta County to Western Colusa County-Northeast Foothills/Sacramento Valley-Northern Sacramento Valley-Northern San Joaquin Valley-Shasta Lake Area / Northern Shasta County-Southern Sacramento Valley.
