.DISCUSSION...
Dry conditions are expected again today, with RH values forecast
to drop below to near 20 percent by this afternoon. However, winds
are forecast to be 5 to 10 mph with occasional gusts up to 15
mph.Should winds be stronger than projected, a special weather
statement will likely be required indicating the increased
potential for wildfires.

Tomorrow is not expected to be nearly as dry as increasing
moisture and cloud cover should keep minimum RH values above 40
percent. Rain is expected to move in late in the day, possibly not
until Tuesday evening.

Large high pressure over the Northeast United States will
continue to move east today and then move off the New England
coast tonight. Low pressure over the Gulf Coast states will lift
to the north and east and affect the Mid-Atlantic region during
the mid-week period, with wetting rains anticipated. Another low
may affect the region late in the week, followed by a cold front
next weekend.
