.DISCUSSION...

Relative humidity values will only drop down to the mid 20s at its
lowest point Monday afternoon. To start the day, around sunrise,
RH values will be in the mid 80s, so we will start the day moist.
Wind speeds will be light and variable to start the day, but
eventually getting a more southerly dominant component by the
afternoon hours. Wind speeds will only be around 10-15 mph with
perhaps an occasional gust to 20 mph this afternoon. Overall, not
a bad Spring day for the Panhandles with highs in the 70s.
