.KEY MESSAGES...
- Patchy fog again tonight, but less than this morning.
- Dry and mild weather through most of next week.

.SHORT TERM /THROUGH SUNDAY/...
Issued at 237 PM EDT Sat Sep 27 2025
Pattern Synopsis: A weak cold front crosses the area late this
afternoon into this evening. Surface high pressure and upper-
level ridging prevail through the rest of the period.
Forecast Details: The above mentioned front is moisture starved
and is expected to come through dry. The only rainfall currently
associated with the front is across northern Ontario north of
Lake Superior. Do not expect this trend to change...with only a
band of clouds anticipated with fropa.
Building heights and surface high pressure follow the front
which will keep the remainder of the period quiet. Still expect
some patchy fog tonight with the relatively good radiational
cooling conditions anticipated. However, with several hours of
good insolation occurring across the forecast area this
afternoon, and low-level dry advection behind the front, expect
much less fog than the past two mornings.
Low temperatures tonight will be near normal, mainly in the 40s.
Temperatures should rebound nicely again for Sunday, with
another day of widespread 70s which is well above normal for
late September.

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Issued at 237 PM EDT Sat Sep 27 2025
Pattern Synopsis: A blocky pattern remains over the region for
most of the week, with broad upper-level ridging remaining in
place across most of the lower 48 states. Forecast area will be
under the influence of this upper ridging and associated
surface high pressure during most of the period. However, a
back door cold front is forecast to slip south across the area
later Tuesday bringing cooler, but still mostly above normal
temperatures to the area.
Forecast Details: Quiet weather persists through the period due
to persistent upper-level ridging, surface high pressure, and an
associated dry air mass. The dry air mass will allow for large
diurnal temperature swings, with daily lows near normal in the
40s, and daily highs well above normal mainly in the 70s.
Wednesday looks to have the coolest high temperature readings in
the 60s behind a dry back door cold front.
The main forecast concern with the dry air mass in place will
be potential fire danger increases with low afternoon RH values.
Have lowered afternoon dew point/RH values to the lower end of
model guidance into the middle of the week. On the plus side,
winds continue to look rather light into the middle of the
week. The dry air mass may also allow for chillier than forecast
overnight lows, with readings falling into the 30s definitely
possible across inland areas.

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 105 PM EDT Sat Sep 27 2025
Skies to generally remain clear this afternoon, save for near CIU
where it will take longer to scour out moisture...and this is where
the threat of showers (if any develop) will likely be between 21z-0z
as a front drops in; otherwise...front may do very little except
kick up some MVFR cigs again between 21z and 03z from west to east.
Think it will be drier behind the front tonight...but still
anticipate potential for fog/low stratus overnight, and have
included this in the TAFs attm, particularly for MBL. A touch gusty
at times this afternoon, 15-20kts...but otherwise, generally from
the W through the night 5kts or less. Expect few if any clouds
Sunday after any fog burns off early...with light W/SW winds.
