TODAY: Thursday starts cooler than Wednesday, with temperatures and dewpoints both in the mid-60s. High pressure has kept skies mostly clear as well, but with approaching showers to the west, we may inherit a few clouds through the morning. These will struggle to make it into mid-MO this afternoon, and even if they do, rain will have to overcome dry air to make it to the ground. Overall, today looks partly cloudy, with a bump in cloud cover this afternoon. Expect a high temperature approaching 90.
TONIGHT: High pressure will slide east overnight. At the same time, high clouds will start to move in; a product of approaching storms near the Omaha area during the overnight. With added clouds, and a south-turning wind, we'll see temperatures bottom out in the 70s.
EXTENDED: By sunrise Friday, showers and storms will be approaching mid-Missouri. Thanks to high pressure, some drier air, and an overall lack of energy for storms to work with, these will be decaying, and pose no severe threat. On Saturday, big southerly flow both at the surface, and above our heads will contribute to a very warm day. Temperatures will jump into the upper 90s, which gives us the chance to feel triple digit heat index values. The heat won't last long, as a cold front will move through Saturday night. There is some uncertainty just how much storm chance we see with the front. It's expected to pass through an atmosphere with plenty of energy for storms, but thanks to a small layer of warm air above the surface, we may not be able to trigger storms. If we do get storms to develop, strong to severe storms would be a possibility. But as of now, especially given the uncertainty, the chance is low. Still, the passing cold front will bring northern air, which will make it feel much more tolerable from Sunday through the middle of the week.
