St. Louis wakes up mostly cloudy and already a bit sticky this morning, with temperatures near 59°F and noticeably muggy air. Skies are expected to flip to mostly sunny and push the high to around 87°F on Thursday, June 4, as southerly winds start pumping more humidity into the region.

This Afternoon And Tonight

Mostly sunny skies hold on through this afternoon with highs near 87°F and south winds between 3 and 12 mph. Tonight stays mild and a little soupy, with a low around 68°F and only a very small chance of an isolated shower outside the core metro into the late evening.

Weekend And Early Next Week

Friday, June 5, warms to about 89°F with a slight chance of showers and thunderstorms after 1 p.m., as southerly winds of 8 to 13 mph may gust to around 20 to 21 mph. Saturday, June 6, heads into the low 90s with only isolated storm chances, but the rain threat ramps up from Sunday, June 7, through Tuesday, June 9, when scattered to numerous showers and thunderstorms are likely, with Monday, June 8, currently carrying the highest chance for organized storms. Some storms could be strong, but a widespread severe outbreak is not expected, according to the National Weather Service St. Louis.

Impacts And Local Resources

Humidity paired with highs in the upper 80s and low 90s will make things feel pretty sticky, so drink plenty of water and work in some shade breaks if you are spending time outside. If the heat or storms throw off your plans, you can find a list of community cooling centers on the City of St. Louis and call ahead for hours and availability. Downtown options include the Central Library and St. Patrick Center.
