.DISCUSSION...
A cold front will move through the region later this morning, and a
drier airmass will spread into the region this afternoon. Surface
dew points drop from the upper 50s to low 60s early this morning to
the 40s to low 50s for most of the area this afternoon, except for
Delmarva, where it will take some time for the drier air to arrive.
It will still be warm with highs in the 70s to near 80. This results
in MinRH values generally 35 to 45 percent. Northwest winds will
increase this afternoon to 10 to 15 mph with 20 to 25 mph gusts.
Winds diminish fairly quickly after sunset this evening.

For Friday and Saturday, daytime minimum relative humidity values
are forecast to range from 25 to 35 percent. Westerly winds increase
to 10-20 mph with gusts 25-30 mph during the day Friday, then
gradually diminish Friday night. A lighter northerly wind is
forecast for Saturday. Given the continued very dry conditions and
increased winds, there is an increased risk for rapid fire spread on
Friday.

Showers are forecast to result in a wetting rain later Sunday into
Monday.

Continue to follow burn restrictions and check with your state
and local fire officials for more information
