.DAY ONE...Today and Tonight

Isolated to scattered thunderstorm development is once again
possible this afternoon. The better coverage of storms will be
over the central and southern mountain ranges with drier air
infiltrating up north. Outflow winds remain a threat with gusts
of 35 to 45 mph possible in some of the storms. Localized areas of
heavy rain also possible in the south which could lead to some
runoff problems. Lightning is a threat with every storm.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

The monsoonal returns to our region by Wednesday morning and will
bring an increase in thunderstorm coverage by the afternoon.
Localized flooding due to heavy rainfall rates will become more
likely tomorrow through the end of the week as this moist air mass
remain in the area. Some storms will also be capable of producing
gusty outflow winds but every storm will have the potential to
create dangerous cloud to ground lightning.


Spotter activation is not expected today however they should be
ready to be on standby the next few days as heavy rainfall rates
and flash flooding becomes more of a threat.
