.DISCUSSION (Today through Sunday)...
Issued at 1157 PM EDT Sat Oct 3 2026

The seven day forecast remains the epitome of the old forecaster`s
adage - Big Bubble, No Trouble.

Dry weather is forecast throughout the next seven days due to the
expansive influence of strong surface high pressure. Broadly
cyclonic flow will be in place over the region, though any forcing
from shortwave troughs pivoting through this flow will be displaced
well to the north, leaving the primary impact to the area to be mild
temperatures and low humidity throughout the period.

Temperatures will be mild and pleasant, with substantially less
humid conditions than experienced in recent weeks. This leaves the
primary weather hazard of concern as fire conditions, with afternoon
relative humidity values likely to drop into the 30 percent range on
many if not most days, and possibly even lower as blended guidance
often struggles to fully capture the degree of mixing out of
dewpoints in the afternoons with plentiful sunshine, even in
settings with relatively light surface flow.

Additionally, there is at least a low chance for patchy frost mainly
northeast Monday night into Tuesday morning as lows will have the
potential to drop into the upper 30s. Current numbers appear too
warm to support anything widespread or significant, but if we can
drop a couple/few more degrees in the outlying areas this may be on
the table.

In any case, several days of pleasant Autumn weather are expected
over the next week, and all are encouraged to enjoy the prolonged
period of mild fall days and cool nights.
