Here is the six hour forecast valid 10 PM tonight (Saturday) with sea level pressure (the solid lines) and precipitation. Two coasts, two storms. For us, a warm front is now moving through the region, and you can see the band of precipitation associated with it on a recent radar image (graphic). Temps will warm up as the warm front pushes north. Then late tomorrow the cold front front will hit us, with substantially increasing precipitation (see 24-h amounts ending 4 am on Monday). Unfortunately, it has been warm enough to rain in the mountains...not very good for the snowpack. More Cascade-concrete in the making!
In contrast, the east coast is getting a powerful, but tightly wound, Noreaster. Strong winds and heavy precipitation along the coast areas..with temps cold enough for snow. What does that spell? Blizzard. DC has already gotten over a foot and some locations are getting as much as two feet. Eastern LI should really get it. Here is the current radar for the New York area...see how nice it is to have a coastal radar to see precipitation moving in from offshore...or seeing approaching low centers?....in a few years, we will have it to.
