Right now, it's looking like the coastal storm's track will have the following impacts:
NJ shore, 3-6 inches
Philadelphia, Lehigh Valley, interior NJ, 1-3 inches
Berks, Lancaster, a few snow showers, accumulating a coating to an inch.
The storm will be a direct hit for the Boston area and for Maine, where it will dump 18-24 inches of snow and produce blizzard conditions.
So here's my full forecast for the next five days in Berks:
Tuesday 1/2: sunny and breezy with a high of 22 (wind chill 12) and a low of 8 (wind chill 4).
Wednesday 1/3: partly sunny and still cold, but with calmer wind. High 29 (w.c. 25), low 18 (w.c. 16).
Thursday 1/4: overcast, cold. A few overnight snow showers or flurries (Wed into Thu). High 22, low 6.
Friday 1/5: COME ON. It's going to be even colder. Very windy. High of 13 (w.c. -7), low of 2 (w.c. -15).
Saturday 1/6: Just rudely cold. High of 12 (w.c. -4), low of 1 (w.c. -7).
Beyond: A bit less frigid on Sunday 1/7 and then it might actually get above freezing on Monday 1/8! There's a good chance for some snow and ice on that day, though.
Stay tuned for updates!
