.DISCUSSION...

There may be a few passing showers in the area this evening, but
no imminent rain is expected near the site for a few hours yet,
until 10pm or so. However, any shower or storm in the area will be
capable of producing outflow winds, so conditions will need to be
monitored. Outflow boundaries can be seen on radar (as of 615pm),
moving in from the north, which will turn winds out of the north
later this evening. Winds should generally be sustained around 15
mph, though a few isolated gusts could be higher. If a stronger
thunderstorm forms nearby, winds will become much stronger.

Thunderstorms will move down late tonight and into early Monday
along a boundary from the north. While most of the activity will
be east of the highway, some intermittent heavy rain, gusty winds,
and lightning will all be possible, with chances ramping up after
3am or so and lasting into the morning hours.

Conditions will dry out across the area by Monday afternoon.
Winds will generally be out of the east, with high temps in the
70s and RH only dropping to around 40%.
