Updated: Final Accumulations for the Feb 5-7th Storm...

Discussion...

We made a few slight adjustments here and there with regards to accumulations. In the ground zero zone, we combined the two separate dashed areas of 24-32" to encompass DC and Baltimore, where there is liable to be some 28-30 inch amounts in their western suburbs. We also bumped up the upper bound to 36 inches for the dashed area to account for the mountain locations in the zone. Would not be at all surprised to see someone in the apps to even see more than that.

Other changes we made was to bring the 12-24 range slightly higher into PA, now cutting into the second tier of counties. Additionally we took a couple counties in WV out of the 12-24 range due to some mixing issues, but didn't go too crazy with the axe there. Those areas should turn over to all snow and still get significant snow.

Keeping an eye on...
NYC metro: We have most of NYC proper in our 3-7 range, and attm that looks like a good call. Very tough forecast, things could go either way in that city.

The rest of southern PA under I-80 (western) and I-78 (eastern): Theres still a chance that the very heavy stuff makes better penetration into these areas for at least a time and makes for amounts that could get somewhat comparable to further south.. especially if significant banding sets up with potentially better ratios.
