The rain tapered off for many of us this afternoon, and the bulk of the rain is now done falling. We will keep the clouds around and some isolated to scattered showers tonight into Wednesday, but we should not see any more major rainfall totals.
Now our focus in the short term shifts to Wednesday night into Thursday morning. The upper level low back to our west near El Paso, TX is moving in our direction. This low will pass directly over us late Wednesday night and Thursday morning. Now, in an upper level low, the center of it is full of colder air, and this cold air will pass over for about 6 to 12 hours. During this time, it will be cold enough and have enough moisture for some snow flakes to form and actually make it to the ground.
Now before you run out and buy every store out of milk and bread, we will be above freezing the whole time so the snow will not stick (not to mention we are WAY too wet and the ground is WAY too warm to stick anyway) and the snow should mix with rain as it falls.
The best chance for seeing snow mixing in will be along and east of Highway 15 with the absolute best chance of snow being along and east of Highway 17 (all of our Alabama counties). Snow and rain will end Thursday morning with skies clearing and full sunshine ahead into the middle of next week.
After we get the sun back, a major cold blast is on the way for the middle of next week. As of now, it is too early to say how cold, but it looks to be the coldest air of the season and could linger for a couple of days (no precipitation is expected though, so don't get your hopes up for snow).
