Could we have a late arriving spring in '08? I think so, at least in terms of March's weather. Many long range forecasting tools indicate a cold March for much of the east coast. It's difficult to tell if this cold air will combine with any moisture and lead to winter precip, but it's worth watching, especially early in the month.
In the more short term range, a deep east coast trough will develop later next week bringing another spell of below n0rmal temperatures. Since there is no blocking taking place, the trough will be rather progressive in nature and scoot out by late next weekend. The models have been shaky, at best, in the mid range, so it's difficult to pinpoint exact details beyond 72hrs.
