St. Louis is starting Thursday with clear skies and temperatures around 47 degrees, but the day is set to warm quickly under mostly sunny skies. The high should reach about 62 degrees, with winds turning gusty out of the northwest Thursday afternoon and evening. It is a pretty good case for taking the long way home—at least until the sun starts giving up later.
Clouds Return Thursday Night
Clouds will thicken Thursday evening, and there is a 20% chance of light showers later in the evening into the night. The National Weather Service in St. Louis forecasts a low near 46 degrees with northwest winds around 8 mph, and no watches or warnings are in effect.
Friday Brings A Sharper Chill
Friday will be cooler, with lingering low-level clouds during most of the day and improvement beginning as dry air moves in; the high will be near 55 degrees, with temperatures slipping toward the low 50s during the afternoon. By Friday night, skies should clear and temperatures could drop to around 35 degrees.
That weekend chill matters more outside the city than in it: rural areas, sheltered river valleys and other low-lying spots have the best chance of a light freeze. St. Louis’ urban heat island may keep the metro from cooling quite as quickly, but anyone with vulnerable plants should be ready for a colder night.
Warm Weather Returns Next Week
Saturday stays mostly sunny with a high near 54, followed by a sunny 60-degree Sunday. The forecast then climbs to 66 Monday and 67 Tuesday, with mostly clear nights and dry weather continuing into Veterans Day.
For city plans, Thursday afternoon and Sunday look like the easiest outdoor windows. Friday night and Saturday morning are the bundle-up portions of the forecast, especially in open or low-lying areas.
