St. Louis starts Friday, October 30, near 59 degrees under partly sunny skies, then warms quickly to a high around 78. The afternoon looks like one more easy window for patios, errands and outdoor plans before clouds and showers complicate Halloween weekend.
Friday should stay partly sunny, with winds turning easterly at around 10 knots (about 11.5 mph) and only a small chance of rain. No watches, warnings or advisories are in effect, according to the National Weather Service in St. Louis.
Halloween Stays Mild, But Clouds Move In
Saturday, October 31, brings mostly cloudy skies, with a chance of daytime sprinkles; light rain is most likely late Saturday evening. Temperatures should still reach about 70 degrees, with light east winds.
Saturday night carries a higher 50% chance of showers. The forecast does not call for a washout, but anyone heading out for trick-or-treating or Halloween events should keep a light rain layer nearby.
Sunday Starts Showery Before A Wetter Week
Sunday, November 1, brings showers before noon, followed by mostly cloudy skies, with a high near 73. Weak ridging promotes a dry start to the work week; widespread rain is expected from very late Monday through at least early Thursday.
The updated outlook is a more active turn than the earlier Halloween forecast covered by Hoodline. Rain chances reach 60% Tuesday, November 3, followed by another chance of showers Wednesday.
Friday Morning Winds Stay Light
The National Weather Service describes light winds Friday morning. It also says widespread, beneficial rain may develop from late Monday through early Thursday, though the exact rainfall totals remain unsettled.
By Thursday, November 5, conditions should trend drier and mostly sunny with a high near 68. For now, Friday is the warm-and-dry standout, Halloween is mild but cloudier, and early November looks ready to bring the rain jacket back into regular rotation.
