.DISCUSSION...
A shortwave trough this evening and tomorrow evening are expected to
bring a few isolated to scattered showers and storms. A few may be
strong with gusty winds and hail. A drier pattern is expected to come
in the latter half of the week, so conditions will try to creep back
toward elevated fire weather. There is low confidence on when fire
products will be needed again.
