(St. Louis, MO) — There appears to be some relief on the way from the recent stretch of excessive heat and humidity in Missouri. National Weather Service- St. Louis Meteorologist Jon Carney says, however, it won’t come until next week. He says the state’s been gripped by a high pressure system or “heat dome” which has kept the jet stream and cold fronts far north of Missouri. Carney says, however, that high pressure system is expected to weaken next Wednesday, allowing for a cold front to bring some much-welcome relief from the recent oppressive weather. He says day-time highs Wednesday will still be in the 90s, but Thursday’s temperatures will be in the 80s. He also notes it will be less humid.
Carney says the arrival of the cold front means a greater chance for showers and thunderstorms as well.
In the meantime, hot, humid weather will continue for several more days. Carney reminds Missourians to drink plenty of water noting there can be cumulative effects of the heat and humidity.
An Extreme Heat Warning remains in effect for the St. Louis area thru next Tuesday evening. A Heat Advisory remains in effect util next Tuesday night for the southern two-thirds of Missouri.
Author’s note: While this heat is tough on us humans, the home-grown tomato plants seem to be loving it!
