.DISCUSSION...
KEY MESSAGE 1...No impactful weather this week with high pressure
keeping the region dry and seasonable.

Modified Canadian High pressure centered north of the area under
broad mid-level troughing will keep the region dry through at least
Fri. Temperatures slightly below normal today return near normal
Wed through the end of the week.


KEY MESSAGE 2...Unsettled weather may return this weekend with
confidence increasing.

Anticipated tropical activity well to the south and west will
interact with a large and quite moist atmospheric river moving
over the area to provide another good rain event this weekend.
Although still a few days out confidence is increasing with
development of a tropical system moving into the lower
Mississippi Valley with deep isentropic lift setting up over
our area late Saturday through Sunday. Total rainfall amounts
could be in a range of 2-4 inches with locally higher amounts.
Temperatures will be somewhat above average citing the moisture
and there doesn`t appear to be much if any cold air advection
early next week when conditions dry out.

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
