CTP is worried about breaking the internet! They are feeling it in their discussion update this morning!
“Small waggles in the storm track on this or that model are
mainly distracting at this point. The preponderance of guidance
from man and machine is that we will be in the bullseye for the
highest snow amounts over all the eastern U.S. for this storm.
The changes overall to the Wednesday-night 24 hours are very
very small. But, as one forecaster said, we may end up breaking
the internet when we publish the first storm-total SF forecast
for the impending storm very shortly. The contours will go up to
20". The lowest numbers are in the NW. After collaboration with
WPC and the neighboring offices, we have settled on a Winter
Storm Watch for most of the CWA. We have left the NW 6-7
counties out for the time being, though their totals do look
like a good 4-6". Nothing to sneeze at, surely. The majority of
the snow will fall between 18Z Wed and 06Z Thurs, but we used
the rough 8" contour for the watch as a starting point as the
snow will probably be longer than that simple 12hr period.
There may be additions to the watch later today.”
