KEY MESSAGES

- Well-above normal temperatures, with areas of Moderate HeatRisk today-Friday.

- Chances (10-20%) for isolated mountain showers and thunderstorms Friday afternoon. - Cooler, breezier weather by the weekend; strongest west-southwest winds in the Delta and vicinity locations.

..The Weekend-Tuesday

Cooler temperatures are on track for this weekend and into early next week as broad troughing builds over the region, strengthening onshore flow. High temperatures cool to near-seasonal for mid to late May by Saturday. Onshore flow will steadily increase through the weekend, peaking on Monday with west to south gusts 20 to 30 mph in the Sacramento Valley/Delta.

More uncertainty appears in the ensembles and clusters regarding the synoptic pattern Tuesday onward. The majority are in agreement showing a trough descending from the Pacific Northwest into the region, but diverge on it's track and strength. This would mean the difference between increased onshore flow or north winds developing in the Valley mid next week.

AVIATION

VFR conditions are expected over the next 24 hours. Light and variable winds less than 10 kts expected through the period. West- southwesterly winds increase through the Delta after 22Z Wednesday with gusts 15 to 20 kts at times through 06Z Thursday.

STO WATCHES/WARNINGS/ADVISORIES
