From flooding rain to snow, there’s a little bit of everything in this forecast.
The rain really picked up in intensity overnight. Because of that, there is a flood watch in effect for the I-95 corridor through Wednesday afternoon. Expect rounds of heavy rain to continue blanketing Maryland through the day. At the same time, it has been a warm rain – but that is going to change.
We started out the day in the 60s, already hitting our highs. Temperatures will fall through the afternoon as colder air gets closer. Then, the low pressure along the front will connect with that colder air and yank it into the storm as it passes by Wednesday night. That will cause the rain to change over to snow. The changeover will happen during the day in western Maryland, but won’t happen until later Wednesday evening through the overnight here in the metro area.
You have to remember that the ground is very warm to start out, so if the snow doesn’t come down hard enough, it will melt pretty quickly on the roads. However, there is a window of a few hours where the snow could come down heavily, leaving a small accumulation. We could get a coating – 1 ” in Baltimore, Anne Arundel and Prince George’s Counties. Those amounts jump to 1-3″ from Baltimore County north and west. Extreme western Maryland could get a few inches more. A winter weather advisory goes into effect starting at 7 p.m. and will continue through 3 a.m.
This storm will get out of here quickly Thursday, allowing some sunshine to return. However, the colder air will linger. Highs will only top out in the 40s each day into the weekend with overnight lows below freezing. Our average for this time of year is 48 degrees, and we will be at or below that.
