Halloween Morning Weather: Fog and 68 Degrees in San Antonio, a High Near 74, and Election Day Rain at 57 Percent

San Antonio starts Halloween damp and gray. The station's live Open-Meteo feed, read this cycle for the Weather Desk's 05:00 file, showed 67.7 degrees and feeling like 72 under overcast skies, and Saturday itself is coded 45 — fog — with a high of 74.1, a low of 66.9 and a 5 percent precipitation chance. Trick-or-treat hours this evening sit in the same mild air the pre-dawn file carried, with no rain in Saturday's numbers.

Sunday, November 1, reads overcast at 77.8 with a low of 64.4 and a 3 percent chance — the day the clocks fall back. Monday turns foggy again in the code but warm, 85.4 with a low of 69.2 and a 3 percent chance, the warmest day in the seven-day run.

Election Day is the week's weather story. Tuesday, November 3, reads rain showers (code 80) at 76.6 with a low of 63.3 and a 57 percent precipitation chance — the figure that jumped from 43 percent overnight and held in this morning's file. Wednesday clears to sunny at 75 with a 2 percent chance, Thursday is mainly clear at 77.5 with 4 percent, and Friday, November 6, reads mainly clear at 79.1 with 7 percent. Tuesday voters should plan for rain; the rest of the week does not ask for an umbrella.
