I put no faith in the weatherman. You have as much chance of predicting the weather yourself. Best to wait until the day or two before to get any kind of accurate prediction. My guess is it will chance significantly by next week.
Re; weathermen. Anyone remember Jim Obrien from channel 6 in Philly? That guy had nothing of today's fancy weather radars, and whatnot, yet he had probably a 96% accuracy rating from a prediction standpoint.
