.DISCUSSION...
High pressure over the Northeast will retrograde back towards
the Ohio and Tennessee Valleys today as Hurricane Teddy
approaches the Canadian Maritimes. Dry conditions are expected
through the week as a result. For today...winds will be from the
northwest and increase late this morning into this afternoon with
gusts above 20 mph likely. Minimum relative humidity of around 30
percent is expected, increasing the potential for fire spread given
the breezy conditions anticipated. Good recovery is expected
tonight as winds diminish to around or below 10 mph. Northwest
winds will likely be lighter on Wednesday with higher minimum
relative humidity values during the afternoon compared to today.
