St. Louis – Residents reveled in balmy conditions as temperatures climbed to 82 degrees Fahrenheit Tuesday afternoon.[1][2] Meteorologists predict this pleasant weather will hold steady through Thursday, featuring highs near 80 degrees under mostly sunny skies. A shift arrives Friday, however, with widespread rain and thunderstorms expected to disrupt the dry pattern.[3]
Tuesday’s Heat Sets the Tone
Southwest winds boosted afternoon readings to 82 degrees on Tuesday, marking a notable warmup for early spring.[1] Conditions remained fair into the evening, offering comfortable outdoor opportunities. This surge above seasonal norms surprised some, as April averages hover around 68 degrees for highs.[4]
Forecasters noted lighter breezes contributed to the sustained warmth. Overnight lows settled in the upper 50s, setting up similar patterns ahead. Such spells provide a preview of summer but remind locals of the region’s variable climate.
Sunny and Mild Wednesday Through Thursday
Wednesday unfolded with abundant sunshine and highs reaching 78 to 82 degrees, accompanied by southwest winds at 5 to 10 mph.[5][6][7] Breezes eased compared to prior days, enhancing the enjoyable feel. Lows dipped to around 57 to 60 degrees overnight under mostly clear skies.[8]
Thursday promises more warmth, with temperatures pushing into the low 83s and south winds strengthening to 17 mph.[6] Partly sunny conditions prevail, keeping precipitation chances at zero percent. Dry air dominates, ideal for outdoor plans before the weekend shift.
Friday Brings Rain and Thunder
A frontal boundary ushers in showers and thunderstorms Friday morning, with highs cooling to 76 degrees and an 80 percent chance of rain.[6][3] Lows fall to the mid-50s amid widespread precipitation. Winds shift west-southwest at 9 mph, potentially fueling storm activity.
Expect 1 to 2 inches of rain in some areas, easing drought concerns but prompting flood watches.[9] Severe risks remain low, though gusty winds and heavy downpours warrant caution. The system clears by evening, leading to drier air.
Weekend Outlook and Beyond
Saturday offers partial relief with highs near 74 degrees and just a 10 percent rain chance, winds from the north at 10 mph.[6] Sunday stays mild around similar levels. Early next week could see returning storm chances.
