Discussion
A cold and stormy weather pattern is getting locked in for the eastern US and there may be three different systems to deal with over the next week or so. Low pressure will head in our direction today and it’ll produce some accumulating snow around here tonight with a coating to an inch or two inches likely by morning. There is a chance that the snow changes to sleet and/or light freezing rain towards daybreak just before the precipitation ends. A much more significant and complex storm is going to impact the I-95 corridor this weekend and everything is on the table for this event including heavy rain, and accumulating ice and snow. Precipitation is likely to begin in the afternoon on Saturday as rain or a wintry mix and then likely changeover to rain at night. The rain could change to sleet, freezing rain and then snow on Sunday as colder air rushes in behind the system. In fact, a plunge in temperatures late Sunday following the departure of the storm can cause a quick freeze-up on many surfaces with potential hazardous conditions developing. The coldest air mass of the season so far will likely result in single digit lows by early Monday morning and highs may very well be confined to the upper teens to start the new work week.
