Overview
- Forecasters say a warm, dry midweek with highs in the 60s–70s will give way to a more active pattern late in the week.
- Most models and local teams now show the greatest chance for measurable rain arriving late Saturday night into Sunday morning.
- The Southwest and parts of Texas have the highest overnight rain odds because of Tropical Storm Vance’s moisture and Pacific low pressure, while many Northeast and Midwest areas still expect a largely dry Halloween daytime.
- Most forecasts call for generally light totals of a few tenths of an inch, but some coastal and valley pockets in Southern California and West Texas could see locally heavier amounts.
- Forecast confidence is limited and timing remains uncertain, so local meteorologists urge viewers to check hour‑by‑hour updates and note that Daylight Saving Time ends this weekend.
