.DISCUSSION...
Dry and cool weather continues today with RH values 30-45% range
this afternoon, but good RH recovery is expected tonight. Clouds
will keep Wednesday a bit cooler as a disturbance brings a chance
of showers to the area with the best potential for wetting rains
over portions of southern NH. Dry conditions are then expected
Thursday through Saturday with a gradual warming trend.
