A low pressure system is going to move from the Texas Panhandle to Lake Erie by Wednesday Morning. This system will be strong enough to pull up a large amount of warm air from the Gulf of Mexico, which is both a good thing and a bad thing. The good thing is that the warm air will give this system a lot of moisture to work with, but that bad thing is that the warm air will likely warm temperatures enough so that at least some of our precipitation will likely fall as rain. Expect precipitation from this system to start as snow tomorrow afternoon and continue overnight. Tuesday Morning's commute will be horrible, as there will likely be around 3" of snow on the ground already and snow will likely still be falling. The main question with this storm is what will happen during the day on Tuesday. Depending on where the storm tracks, we could get a lot of snow, a lot of ice, or a lot of rain. Right now, it is looking like we will get a lot of rain. Then as the storm moves away, we will likely get a few more inches of wraparound snow Wednesday Morning.
As of right now, I will put a LOW snow day alert out for Wednesday and Thursday, due to the fact that we may yet get ice or snow as opposed to rain on Tuesday, and also due to the fact that even if we do get rain, it will all freeze over on Wednesday. This forecast is highly subject to change, as this system has been a nightmare to forecast so far and I can't see that changing. Although I would usually put out a snow map by now, there is enough uncertainty that I will hold off on doing so until this afternoon or tomorrow morning.
