Sandy is expected to make landfall this evening, by that time possibly going from a tropical system to a non-tropical weather system, but either way doing extensive damage. The first map below shows the broad wind field and the potential of tropical storm force winds (excess of 39 mph).
The second map shows the heavy rainfall that will be produced over the next several days, with many areas picking up 5-10".
The third map shows the heavy snow expected over the Eastern Kentucky and West Virginia Appalachian mountains. Higher elevations could pick up over a foot of snow.
The final map shows the slow progress of Sandy. Although weakening, the storm will still be sitting over Pennsylvania and New York through Wednesday. This will make clean-up and power restoration efforts difficult or impossible for several days.
Locally, our main impact will be gusty, chilly winds. A Wind Advisory is in effect from 4pm today through 8pm Tuesday. Winds will be from 20-30 mph, with gusts to 40-45 mph.
