.DISCUSSION...

Good morning!

Rain showers developed early this morning and chances for showers
and thunderstorms will only increase through the day. Expecting
mainly shower activity for this morning at least through 9-10AM
with better chances for any thunderstorms holding off until mid-
day and thereafter. That said, an isolated thunderstorm occurring
in or around Alpharetta this morning is not out of the question
given the current environment. Any storms that form will be
capable of gusty erratic winds, frequent lightning and locally
heavy rainfall. Shower and thunderstorm activity should largely
begin to taper off between 8-10PM. Outside of any thunderstorms
winds will be from the southwest less than 10 MPH and skies will
be partly to mostly cloudy.

Please reach out with any additional questions or concerns.
