Three packets of energy are forecast to make a bundle when they rendezvous on the east coast on Tuesday. All the packets are over the North American continent as of this morning and the accuracy of the computer weather models will increase with this morning’s run and the following runs.
If they come together here, if it’s snow, plan to take Tuesday and perhaps Wednesday as ‘watch the snow’ days.
If you want to see the colliding packets of energy in action, a neat video is at the National Centers for Environmental Prediction. Here’s the link, below. If the direct link doesn’t work, it takes lots of clicks, clicking on North America, the nam model and the sim radar. The simulated radar shows the precipitation with the three packets of energy, from the midwest, the southern atlantic coast and the gulf of Mexico smashing together, making one area of snow and rain over the northeast megalopolis.
The game plan is for heavy snow from I-95 inland from DC to Maine. But this game plan is wobbly, and the rain/snow line is like the scrimmage line or the rugby scrum with the competing forces of upper air energy, moisture and warmth from both the Gulf and Atlantic. Stir with high winds and we have a blizzard watch.
But as they say, you still have to play the game.
