We saw a textbook example of bombogenesis off the South Atlantic coast as a system rapidly deepened bringing gale-force wind, heavy,m flooding rain, beach erosion, coastal flooding as well as some snow. That very beast is now heading NNE with a tropical look. It’s bringing blizzard conditions to the Cape today.

While the Atlantic weather bomb departs, a large clipper system will move in forcing secondary development off New Jersey bringing a second and third opportunity for accumulating snow from DC to Bangor. A lot of upper energy and cold, dry arctic air driving SE will generate a lot of heavy, blustery convective snow showers.

GFS surface shows the active next 2-3 day period over the Mid-Atlantic and Northeast.

Once these lows exit by Thursday, the first of two strong arctic highs descend over the Great Lakes followed by another weak clipper. Behind it, we could see the coldest air in years for the Big I-95 cities.

Snow covered ground, thickness values, 850 temps all combine to potentially bring the coldest air since January 2004. However, we’ve been here before, time and time again and temps haven’t gotten down to the depths of the models.

Record Warmth Out West

With a strong spring-like dome of high pressure building over the Great Basin, a strong NE flow will drive strong Diablo and Santa Ana winds to the coasts of the Bay Area and Southland today and the next few.

See this morning’s video for the discussion.
