.DISCUSSION...
Expect dry and mostly sunny conditions over the burn area through
Tuesday afternoon, with temperatures warming back to near normal
for this time of year. Isolated showers and thunderstorms late this
afternoon and evening are expected to remain just to the west, so
there is a very slight (10%) chance of thunder early this evening.
Winds will be light and variable at times, especially Tuesday
morning. However, the prevailing direction will be out of the
southwest and peaking near 10 mph in the afternoon.
