As we begin the workweek, weather enthusiasts and residents of St. Louis can expect a mix of scattered rain and thundershowers.
While Monday will be marked by cloudy skies and mild temperatures, the week will heat up, culminating in stormy conditions by the weekend. Here’s a detailed forecast of what you can expect over the coming days.
Monday: A Rainy Start
Scattered Showers & Thunderstorms
A cut-off area of low pressure, drifting northward from the Gulf Coast, will bring scattered showers and some thundershowers to the St. Louis area on Monday.
The rain will be widespread throughout the day, affecting commutes and outdoor plans. It won’t be a washout, but pockets of rain and storms are likely throughout the afternoon.
Temperatures & Conditions
In between the rain showers, the skies will remain mostly cloudy, and the temperature will hover in the mid-70s.
Expect moderate humidity, which will make the air feel a little warmer than the thermometer reads. By the evening, showers will begin to decrease, providing some relief.
Overnight Forecast
Overnight, the rain will taper off, leaving behind mostly cloudy skies and temperatures dropping to the low 60s. The conditions will remain mild but comfortable for most.
Tuesday: A Brief Dry Spell Before the Heat Builds
Morning Dry, Afternoon Showers
The morning hours on Tuesday will be dry and relatively calm. However, by the afternoon, scattered thunderstorms will develop once again, especially along and east of the Mississippi River. These storms will bring heavy rain at times and could lead to localized flooding in some areas.
Highs and Humidity
Expect temperatures to climb into the mid-to-upper 70s during the day, accompanied by increased humidity. It will feel a bit warmer as moisture from the Gulf of Mexico contributes to a sticky atmosphere.
Wednesday: Heat Builds
Rising Temperatures
As the low pressure system moves further away, we’ll experience a significant warm-up. Highs will climb into the mid-80s by Wednesday, marking a noticeable shift from the cooler temperatures earlier in the week. The day will be mostly sunny with some clouds, and the humidity will be moderate to high.
Dry Conditions
Wednesday will be a dry day, giving people a break from the rain. This is the perfect time to enjoy outdoor activities before the stormy conditions return later in the week.
Thursday: Almost 90°F
Hot Temperatures
By Thursday, temperatures will climb even higher, reaching around 90°F. Expect another hot and humid day with a mix of sunshine and clouds.
The heat will become more oppressive, with the combination of high temperatures and humidity making it feel warmer than the actual readings.
Limited Rain
There may be some isolated showers or thundershowers, but for the most part, the day will remain dry and sunny.
Friday: Storms and Cooling Down
Thunderstorms Return
A pair of cold fronts will approach the area on Friday, bringing the potential for strong thunderstorms. These storms could be severe, with heavy rainfall, strong winds, and the possibility of hail.
As the cold fronts move in, expect a cool-down in temperatures, providing some relief after the recent heatwave.
Highs and Weather Conditions
Friday’s high temperature will drop back into the low 80s, with conditions becoming more comfortable as the cold fronts bring relief from the oppressive heat.
Weekend Outlook: Cooler and Sunny
Weekend Forecast
By the weekend, temperatures will be much cooler, with highs expected to remain in the 70s. Saturday and Sunday are expected to be dry with sunny skies, making it a perfect weekend to spend outdoors after the stormy end to the workweek.
