.DISCUSSION...
Breezy southwest winds 10-15 mph with gusts to 30 mph today into
early this evening with minimum RH values around 5 percent, producing
brief near critical thresholds. Breezy afternoon conditions will
persist every afternoon into next week due to strong surface
heating. Otherwise, single digit min RH values at all elevations
will persist over the next week, with poor overnight recoveries.
Although confidence remains low at this time, there is the
potential for some mid-level moisture to move into far eastern
areas (along the Arizona and New Mexico state line) by the end of
next week into next weekend. This may lead to some afternoon
buildups and/or isolated dry lightning strikes as early as Thursday,
but more likely Friday into next weekend.
