.DISCUSSION...
A few showers and thunderstorms will be possible this afternoon
as a weak wave moves through. Aloft, the jet stream will move
across the area and with deeper mixing expected, some gusty winds
of 30 to 40 mph will be possible this afternoon and through the
end of the week. Humidities will remain above any critical fire
weather thresholds so do not anticipate any critical fire weather
conditions. Monsoonal moisture looks to make a return for the
latter half of the weekend.
