Multiple systems tracking through the region will cause some messy commutes through mid-week.
Low pressure passed to the northeast through the straits this morning, and is making it's way toward the east coast. It's cold front is draped down across the east through the Ohio Valley, and will become a stationary front - lingering there the next few days until a strong low pressure system kicks it out Wednesday.
A couple of systems will track along the front, causing our viewing area to see rounds of rain, wintry mix, sleet, and light snow.
If you have errands, Sunday evening will be the best time to get them done, or early Monday. We'll be partly cloudy and calm overnight, and start Monday with just some cloud cover.
Mid-morning Monday the first round of rain enters the Central Lower. Expect a rainy Monday afternoon, and for some their after-school activities or drive home from work will be pretty soggy. Rain lingers for the northernmost counties into the evening hours before many dry out a bit overnight.
The biggest concern for your Tuesday morning commute is freezing rain - be prepared to give yourself extra time on the drive in to work or school.
Scattered rain pops up during the morning hours, and the next main round of showers begins around lunchtime - again starting in the Central Lower. Throughout Tuesday afternoon, we'll see rain for most of the L.P. and there's a chance for thunderstorms in the southernmost counties. In parts of the Northern Lower don't rule out wintry mix or scattered snow. Heading into Tuesday evening, we keep wintry mix around for the Northern Lower and mainly rain for the Central Lower. While the E. U.P. has a chance for wintry mix, many will just see overcast skies.
Tuesday night we get another break, but it's shortlived. A stronger low pressure system edges it's way into Illinois in the early morning hours on Wednesday. As of now, rain and wintry mix look to move in very early Wednesday morning (we're talking sometime around 2am) and cover a good portion of the L.P. by 5am. For this reason, Wednesday morning is another one you may need to take it slow on the roads.
This low pressure system will cross through the Ohio Valley through Thursday, keeping our chances of rain, wintry mix, and sleet in the forecast through then also.
With rain, mix and sleet possible across the L.P. and scattered snow possible across the E. U.P. and straits, Thursday morning is yet another one to give yourself extra time heading out the door.
High pressure then moves in for Friday and Saturday, giving a break from the precipitation and allowing us to see a bit more sunshine.
Forecasting systems like this and exactly where the dividing line of rain and mix/sleet/snow can fall is tricky, and we will continue to keep you updated as the forecast may change.
