Clipper Forecasts, -30s in New England

In this blog I show the final AccuWeather.com and NWS predictions for snow amounts from this clipper system. The bottom line is that interior New England will be getting over 6 inches of snow from this system, with 3-6" for the rest of the Northeast except the major cities and I-95, which have a shot at an inch or two. (Side Note:
Meteo Madness Man (PREMIUM | PRO) is freaking out about the March 8th storm now).

However, as I said over in the Forums discussion, I'm a little worried about places hitting their expected high temperatures today. Forecasts have gone down more than 5 degrees in the last 24 hours here in Central PA, and we're starting out at or below zero, so there will have to be some warm advection (movement of warm air) of historical proportions here - it's hard to get more than 30 degrees difference between the low and high. Check out these cold temperatures here in Central Pennsylvania at 7 AM:

Clearfield, PA: -4
State College, PA: 0*
Bellefonte, PA: 1

*My car thermometer showed zero as I pulled into AccuWeather HQ this morning.

But it's not just us, some of the coldest temperatures of the season are occurring in other parts of the Northeast:

Island Pond, VT: -36
Saranac Lake, NY: -29
Westfield, PA: -9
Bradford, PA: -8
Millbrook, NY (Southeast New York): -1
Long Island, NY: 7

Why is this important? If forecast highs don't reach their expected maximums, more snow will stick in the outlying regions of the forecast. Roads may also be worse than expected by the media. Not only do you have the above factors keeping the temperature closer to freezing, there's always evaporative cooling that people forget about. When the snow starts to fall, it can down temperatures by as much as 5 degrees in a minute or two, flash freezing roads.

The NWS forecast snow maps are not that different from ours.
