Expect plenty of sunshine at the burn site today with only a few
high clouds expected to be floating around. The high temperature
should warm to around 67 this afternoon with minimum relative
humidity expected to dip to around 54 percent. Some uncertainty
exists in how warm we will get this afternoon. There are scenarios
where we reach the lower 70s which would lead to lower humidity
than currently forecast. Winds will generally be light out of the
southwest but better mixing in the afternoon could lead to some
gusts up to 15 mph.
Clouds will be on the increase tonight with a low temperature
around 51 and good humidity recovery. Friday will cooler with
breezy west to northwest winds behind a cold front.
