After a record setting day of severe weather in and along the Gulf States, we head in a different direction today as this storm evolves. While there will be severe weather, it shouldnt be anywhere near as nasty as yesterday. The severe weather setup today appears to be along coastal areas of the SE states, mainly NC and SC. Storms will fire, and the potential for tornadoes exists.
Further north, we already have had snow reports in VA, DC and up into Maryland. There is a significant battle going on now between entrenched cold air and the warm air riding up and over the cold. This cold air damming process will result in significant icing conditions to areas in the Amish country of PA through the Lehigh Valley. We have reports of snow that changed to sleet and now back to snow around DC, freezing rain being reported in Columbia, MD with snow further west. So, there is a battle going on, and it seems like it wants to take shape along the I-95 corridor.
Areas further north, like in Central NJ, we have temperatures in the upper 20's to lower 30's with dewpoints in the lower 20's. This is significant because as evaporational cooling takes place, our temperatures will drop and the dewpoint will rise until they meet. Having temperatures drop will create a nasty setup. Eventually though, warm air will win out and we will turn to rain. How long it takes the warm air, how long does the snow and sleet last will be the question.
I expect snow to overspread the area and then mix with and change to sleet. This afternoon I expect everything to change over to rain and come down heavy. It will be a very raw day. Areas just to the west and north of here will have a significant storm on their hands with major icing and further north, major snows.
Updates throughout the day on twitter and facebook!
