Last 90-degree day today, storm chances pick up tomorrow ---
It's been a long, hot stretch so far this June. 13 of the last 18 days this month had been at 90 degrees or warmer! Today will be the last 90-degree day within the next 7-10.
A front sags to our north on the Iowa/ Missouri border. While that front stays well to the north, it will be enough for isolated storm chances in our area this afternoon. The healthiest chance for storms, while still isolated, will be to the north in central Missouri. Storms will most likely pop after 2 PM with the heat and humidity of the day, and collapse by sunset. A rogue strong storm is possible with the threat of 50-60 mph winds.
It will be hot and humid with a south wind surging ahead of that front. Highs will be in the upper 80's to 90 degrees, with a heat index of 96 degrees.
Mostly dry and partly cloudy tonight with lows in the lower 70's.
By tomorrow, an upper-level low-pressure center now spinning over the Pacific Northwest starts to dive into the Ozarks. That low pressure will give way to more widespread showers/ storms, and cloud cover. Showers and storms could start up as early as the morning commute with chances lingering through the afternoon. Most everyone should see some rain by Wednesday night. With the more widespread chance of storms, comes a healthier chance for a few severe storms, stay weather aware!
With the clouds will come temperatures warm, but cooler, in the upper 80's.
This upper-level low-pressure center will hang over the Ozarks on Thursday keeping showers/ storms widespread with highs in the lower 80's.
By Friday we'll be on the back side of the low, so while a few storms are still possible, I think it will be the driest day of the week.
As the low exits, it will leave the door open to more storms to roll in behind it like a series of cars on the highway, a choo-choo train if you will.
Scattered showers and storms are expected both Saturday and Sunday with highs in the low to middle 80's. A few storms could linger into next week.
