.DISCUSSION...
The main hazard this afternoon through Thursday will be low
chances for isolated convection at or near the incident location.
The most likely timing, IF showers or storms occur in the incident
area, would be the afternoon hours. Lightning and gusty winds will
be the main threats. Low level boundary layer winds will
generally be from the south or southeast at less than 10 mph
through the end of the week, but winds could become gusty and
erratic if any convection occurs nearby. Otherwise, seasonal
temperatures and mostly sunny skies are expected.
