Winter Weather Advisories Inland Tonight Mild Saturday Next Storm System Sunday
We are seeing rain and freezing rain moving northeastward tonight and that will be impacting the northeast overnight into early Saturday morning. This is not a big storm by any means and more of a nuisance than anything else. None the less travel will be a bit tricky inland and Winter Weather Advisories are up overnight for areas from Eastern Pennsylvania,
Temperatures this evening are close to the freezing mark inland and in the mid to upper 30s along the coast. Some sleet has been reported in coastal areas but it should go to rain in short order. This will continue overnight but starting around midnight most of the advisories will start to expire across Pennsylvania as temperatures rise. In New England freezing rain continues for most of the night.
SATELLITE
On the regional radars you can see the area of precipitation advancing northeastward with freezing rain showing up as far south as Northwestern Virginia. Rain is occurring further east in Delaware and New Jersey.
As far as ice accretion is concerned most areas may see enough to give a glaze of ice in the next few hours. A tenth to a quarter of an inch of ice accretion will be confined to areas well inland west and north.
By daybreak this will be coming to and end from west to east and the low will begin to strengthen offshore. That brings in dry air behind it and Saturday will see improvement with clouds giving way to some sun, a gusty wind, and afternoon highs in the 50s.
A weak high builds southward Saturday night into Sunday from our north and that will filter down slightly colder air, enough to make the atmosphere borderline for this next storm system headed our way up the coast for Sunday. There isn’t a lot of support here from the upper atmosphere but these sorts of systems can be tricky. Anytime you have marginal cold air around it could lead to surprises in both directions and we are hesitant to talk amounts at this stage other than to say that in areas that stay all snow might see a couple of slushy inches out of this.
The freezing line at 5000 feet for example is the last blue line on the map that runs along the south shore of Long Island and cuts across New Jersey from Sandy Hook West to just north and west of Trenton. Sometimes the intensity of the precipitation could cool the atmosphere down an extra degree or two so we will be watching for that possibility. For now we are just going to sit back and wait to see if we have better clues about this tomorrow.
