Wouldn't it be great if the weather from this past weekend carried on into the new work week? That would be lovely in my opinion. Plenty of sunshine and highs in the 50s and 60s. Unfortunately for this Monday, that isn't going to be the case. We'll see temps stick around the 50s, but the sun is going to have a slim chance of making an appearance. A deepening system over the central plains with tropical Pacific roots has brought a rainy start to our Monday. Before today, the Rockford International Airport has recorded 3.32" in 2020, with .71" (January 10th) being the highest daily rainfall of the year. There is a good chance the soaking rain we see today could eclipse that when this is all said and done.
Unlike last Thursday's system, this mid-latitude cyclone has plenty of moisture to work with and it's all thanks to the subtropical jet. This feature as you can see using water vapor imagery is pulling in rich moisture from the Pacific Ocean and spreading it across the Midwest. This has many, including the Stateline area, waking up to a rainy start. This
morning, rain began to fill in across northern Illinois and southern Wisconsin. Even a few rumbles of thunder were heard in our southern most areas in Lee county, and south of viewing area. The thunder chances
are going to remain primarily confined to the morning, but rain chances
are all day. On top of the rain, strong winds will most likely lead to
wind-driven showers. Southwesterly winds will stay in the range of 15 and 20 mph, with gusts close to 30-35 mph.
Before you head out the door today, be sure to grab the rain gear, including your umbrellas and rain jackets. It will definitely be needed as rain will likely stick around for the entirety of our Monday, with pockets of moderate to heavy rain developing during the late afternoon and evening hours. Once your work day comes to a close, be sure to give yourself extra time and be aware traveling home this evening. These pockets of heavier downpours might slow things down for the commute later on today.
The last of the rain will begin to taper off between midnight and 3 AM as a cold front sweeps through. This boundary will help usher in a cooler and drier air mass for the day tomorrow. Once the rain tapers off, cloudy skies will linger into the predawn hours. As far as rainfall totals, models this morning have slightly come down leaving most with .50" to 1" of rainfall. There will be a chance for higher amounts locally for areas that are impacted by thunderstorms. The good news is, early morning clouds will give way to increasingly sunny skies Tuesday afternoon with highs
near 50°. Enjoy the dry conditions during the day while you can,
because clouds increase late Tuesday ahead of rain and snow chances
early Wednesday.
