Spotty snow moved across Pennsylvania as freezing rain broke out in Maryland and northern Virginia. Then, just in time for the morning commute, the precipitation became heavier. It was so slippery around the Philadelphia area that walking a few feet was an invitation to a nasty fall, and driving conditions deteriorated rapidly. Near Media, Pa., there was a 15-car pileup, and a photo of an overturned salt truck made the rounds on Twitter. Farther northeast, there were snow problems around New York City, Providence, R.I., and Boston.
Here's the morning video. As always, check back for updated videos on AccuWeather.com throughout the day, any day.
With a big high pressure area off the East coast and the nearest cold front in the Plains, there is time for mild air to replace the coldness all the way to Maine. The combination of melting snow and the coming rain will lead to street flooding and stream rises. The National Weather Service monitors the nation's rivers, and here is their outlook for the Middle Atlantic region from this morning.
In the I95 corridor, tomorrow will turn wetter and warmer. Sunday will turn dry and chillier, but no return of really chilly air is likely until midweek, and even then it will not rival the cold wave that swept through this week.
This map shows the pressure pattern at 9 a.m. ET. As the high moves closer and the storm moves farther away tomorrow and Wednesday, there should be an increase in sunshine with milder afternoons.
This map is the GFS forecast for when weekend rain makes its most northward advance early Sunday. The model then shows drying from north to south during the day Sunday. The ensemble mean has the northern edge in the same area. Looking ahead, it appears that warmer air is coming when May starts.
This map shows the GFS model forecast for Saturday evening. In the last day or two, the models have trended northward with the precipitation. If it trends even farther north, the issue of possible snow would need to be addressed. Check back later for updates, please.
The GFS (U.S. Model) predicts a major storm for the Middle Atlantic in the middle or late part of next week. This map is the GFS forecast for next Thursday (April 30) at 8 a.m. ET. Just to put you in a better mood, the second map (for May 4) shows what would be a sunny and pleasantly warm spring day.
This map shows the pressure pattern earlier this morning. You can see the extensiveness of the area of west to east winds. As a storm north of the Upper Great Lakes moves eastward, the flow will become more northwesterly.
This year, the "slight" category has been divided in two: slight and enhanced. When seen together on an SPC map, the progression makes sense. When the term "enhanced" is used alone, it can be a challenge, at least until we get used to it.
