Discussion

It is still several days away and there are several questions yet to be answered, but there is the potential for a major east coast storm during the middle of next week (Wed/Thurs). A storm will drop southeastward from the Pacific Northwest early next week and will likely intensify rapidly upon reaching the Mid-Atlantic coast by mid-week. It is still way too early to tell the exact track of the storm and the rain/snow line will no doubt be an issue to deal with in the Mid-Atlantic given the time of year. Perhaps the odds will favor rain from I-95 and points south and east and snow N and W of I-95, but those kind of details won't be worked out until next week. The "seeds" for the storm are still way out over the Pacific Ocean so we're still a few days away from having a good handle on this system, but the potential is there for the middle of next week.

On another note, yesterday we talked about an almost never seen high pressure reading forecasted by a computer model (NAM) over Greenland for the latter part of the weekend. Well, that has been topped and rather significantly in the overnight run of the same model. Last night's 00Z NAM model run now forecasts an incredible high pressure reading of 1100 millibars which equals 32.48 inches for late Sunday night over Greenland. This is reflective of rather widespread brutally dense and cold air situated up there that actually starts dropping southward into central Canada by later next week (shown in video). Interesting stuff for a weather weenie. Stay tuned as we'll follow the progression of that cold air mass and next week's storm threat.
