Afternoon Forecast/Discussion 4/5/2024: Rinse & Repeat from Yesterday, but with a Twist!

Good Midday & Happy Friday, Cardinals!! I promise you, we have clearing, but we will have to endure another day of overcast skies and periods of chilly rain through most of the afternoon. clearing is already on its way, but when and what do we expect in the meantime? Dive on in with us below!

Another wave of energy from SE Michigan bears the higher potential for exciting the somewhat unstable atmosphere (we have some colder air above the surface helping that out), so shower chances will rise through the afternoon. However, we do have a wave of sinking air behind that which will provide the opportunity for clearing skies around 4 or 5 pm. We may ultimately have to wait for the later evening and overnight hours for our skies to clear in earnest because this system we have been dealing with for the past several days has to clear out first. Our overnight period seems to be the point where a ridge of high pressure looks to do that, but it will be stone cold with light winds slackening off but staying out of the northwest, and clearing skies allowing for a good amount of warmth to escape out to the upper atmosphere by a process known as radiational cooling. This is a process that happens under calmer, clearer, and drier conditions, which are on their way for tonight.

This means that, since we’re cooling to where the air can finally saturate enough to stop cooling down – the dew point which tonight looks to be in the upper 20s – the National Weather Service has issued a Freeze Warning in effect from 2am to 10am tomorrow morning for that eventuality. Stay warm, and have a great weekend, with the warm thought that a warm-up to around then above normal runs through this weekend into next week!
