1.  DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638

Upper level low will move into the region today increasing the chance of some shower activity with the snow level near 2000 - 3000 ft.  Minor ridging will follow overnight.  Other than early morning stability, air mass should destabilize during the late morning and afternoon.  Wind flow will generally be light but with improving mixing, dispersion should be fair to good.

2.  DISPERSION

THURSDAY
Mixing height below 2000 ft early rising to 3000 - 4000 ft by late morning.  Afternoon mixing height rises above 5000 ft then lowers to 2500 - 3500 ft during the evening.
