.DISCUSSION...
High pressure remains anchored overhead today, yielding mostly clear
skies and dry weather. For this afternoon, mixing heights between
1 to 7 PM will reach heights of around 3,000ft AGL. While low to mid
level flow will be light overhead, very dry air from aloft could mix
down to the surface and lower RH values down into the 25 to 30 percent
range. Surface winds are anticipated to be light and variable between
2 to 5 knots. Relative humidity values will rise above 50 percent once
more around sunset this evening.

The next chance for any precipitation is not until the middle of
next week, when a cold front brings some showers, followed by a
noticeable drop in temperatures to close out the work week.
