.DISCUSSION...

Two rounds of scattered showers and thunderstorms are possible
today, with the first round between 9 AM - 11 AM, and the second
round possibly starting as early as 1 PM, but most likely after 2
PM. While it appears unlikely with the first round of thunderstorms,
can`t rule out a strong to severe storm producing hail to the size
of quarters. Rainfall amounts look to remain light, with amoutns
under a tenth of an inch expected. The second round of thunderstorms
will have chances for producing large 2 inch hail, along with strong
damaging wind gusts to 70 mph. This round could produce rainfall
amounts up to half an inch, possibly more if a couple storms move
over the same location.

Aside from storm chances, winds this morning will start out from the
southeast, becoming breezy as they transition towards a southerly
direction by the late morning hours with gusts 25 to 30 mph. This
should allow for improving smoke dispersal throughout the morning
hours. A cold frontal passage will move through the area during the
mid-afternoon hours, swinging winds around to become out of the west-
northwest.
