.DISCUSSION...

...close to marginal fire danger levels for this afternoon...

Frontal passage expected tonight. In advance, wind speeds will be on the
increase with gusts as well. Sfc to 925 mb veering looks like just 10
degrees at most. RH values through the 850mb-925 mb layer are quite low
and some expected mixing will drop surface values down toward 30% by afternoon.
Look for excellent dispersion levels as well given the higher transports.
