DOTHAN, Ala. (WDHN) — We’ve been talking about it all week long: a big system is going to bring a lot of impactful weather to many across the Southeast U.S. With MLK Day parades and other weekend plans in limbo, here’s what you need to know:

Tonight will be seasonably cool with lows around 40 degrees and partly cloudy skies.

We’ll start our Saturday partly sunny and dry, and we should easily warm up to the middle 60s. Showers will move into the Tri-State during the afternoon and early evening hours with moderate to heavy rain and even some storms expected during the evening and overnight hours. Most folks will get 1-2″ of rain, but there will likely be pockets of 2-3″ or even more.

Sunday will probably start off with a few light showers and a few could linger throughout the day. Temperatures will only be in the 40s much of the day. Winds will be quite brisk with sustained winds of 15-20 mph and gusts of 25-30 mph.

Martin Luther King Jr. Day will start off near the freezing mark, so bundle up before heading out the door. Highs will only climb into the low and middle 50s despite lots of sunshine.

Tuesday will be similar to Monday: morning lows around or below freezing, afternoon highs in the middle 50s, and lots of sunshine for everyone.

Wednesday should be a primarily dry and warm day. Lows will start in the middle and upper 30s, but we’ll easily move into the middle 60s during the afternoon. Showers might pop into the forecast Wednesday night.

Thursday has a 40% chance for some shower activity. We’ll start the day in the upper 40s and end up around 60 during the afternoon hours.

Friday brings back those freezing temperatures early in the morning. Mostly cloudy skies will prevent the sun from warming us up much at all, so highs will likely be around 50 degrees.
