.DISCUSSION...
Dry with occasional gusty southeast wind conditions will wane
this evening with the loss of diurnal sunshine. A warm front will
lift northward overnight into Saturday, increasing area cloud
cover and eventually leading to mostly light rain showers with low
probability of thunder. Overnight temperature is expected to
remain elevated given lack of radiational cooling.

Precipitation chances are expected to diminish by Saturday
afternoon behind the warm front as the area sees temperature rise
toward seasonal average temperature. Wind will veer to the south
behind the front and have occasional gusts up to 20 mph.

Expect dry conditions with above normal temperature and lower
daytime humidity values Sunday as ridging and surface high
pressure develop over the region.
