Ding! Ding! Ding! Youre the winner
Ive always statedweather forecasting is only accurate for about 24 to 48 hours
NWS often can't get two different offices to agree on the weather during the same 24 hour period. Taunton MA and Gray Maine often disagree about snow depths, etc. along the NH/MA border. You would think their models would not have discontinuities at state boundaries, since the atmosphere really doesn't know where the boundary is. But the NWS offices do.
