We are beginning our climb out of the brief, but potent, chill we had the last couple of days which means spring-like warmth will soon return. For the rest of Wednesday evening, we'll hold on to the mainly clear sky before cloud cover moves back in later tonight. The increase in cloud cover is the result of an incoming upper-level disturbance from the northwest. We can see those clouds across the Upper Midwest and Plains, and few radar returns moving into northern Wisconsin.
While we may see a brief period of some light precipitation late tonight, it likely won't amount to much thanks to drier air we have down near the surface. Moisture increases aloft, which is why we'll see the increase in cloud cover tonight. But that moisture will be lacking the closer you are to the surface. This dry air will likely limit just how much precipitation, if any, reaches the ground. If we do end up seeing some light rainfall, we will have to keep a close eye on temperatures at the surface because they'll be very close to the freezing mark. However, I don't anticipate many impacts to the morning commute.
Temperatures will continue their climb through the rest of the week as a strong ridge of high pressure builds out west. This will bring several days of 90- and 100-degree heat to the Southwest. Closer to home we won't experience warmth quite that significant, but temperatures warming into the 60s - possibly back near 70 degrees - by the start of the weekend appear likely. The only 'fly in the ointment' would be any lingering fog or cloud cover due to the added low-level moisture from the recent snowmelt.
