.DISCUSSION...
A upper ridge will amplify over the area through today, before it
starts to edge east tomorrow into Tuesday. Temperatures will be
above normal. Some cloud build-ups are expected in the afternoon
in the surrounding mountains, with a limited threat of a shower
or thunderstorm. However the site itself is expected to be
precipitation-free. Winds will be generally light and terrain driven.
Late Tuesday afternoon and Tuesday night a better threat of rain
and possible thunderstorms enters the area as a cold front comes in.
Winds are expected to increase some with the passage of the
front Tuesday night into Wednesday. Periodic shower and thunderstorm
chances will continue into the end of the week.
