.Discussion...
The prefrontal conditions today will feature a continued dry
stretch over the area. Some RH values will get down into the 30%
range this afternoon as well the next couple of afternoons. A cold
front will dive south across the area today and provide the chance
of some showers and possibly a thunderstorm through this evening.
Some wind gusts up to 20 mph will be possible today as well as
the next couple afternoons. While the fuel moistures are still not
quite an issue, the RH and winds will be a concern over the next
few days.
