.DISCUSSION...
Issued at 225 PM EDT Thu Sep 24 2026

500mb ridging in the region will only be occasionally interrupted by
weak shortwaves over the region, including tonight/Friday. These
will bring some periods of higher clouds, but meager if any precip
chances.

An increase in higher clouds tonight should decrease the chances for
both fog and frost somewhat heading into Friday morning. Do still
expect patchy fog again tonight, in particular in ne lower MI,
where higher clouds will take longer to arrive. Fog is expected
to be an issue again Fri night.

Otherwise. high pressure over eastern Canada and then the central
Great Lakes will keep our wx quiet. Lack of precip requires us to
keep an eye on fire wx parameters, but an actually breezy day looks
to be unlikely until perhaps Tuesday. Daytime RH values are also
unlikely to completely crater.

Our next decent chance for precip looks to arrive in the middle part
of next week. Our upper pattern finally tries to become a bit more
progressive, allowing an upper trof and surface cold front to slide
east into the area. This is looking less impressive than yesterday,
with a lot of energy/moisture still associated with a stalled upper
low in the sw states. Even so, rain chances look to arrive
here Tuesday night/Wednesday.

Issued at 1139 PM EDT Thu Sep 24 2026

High clouds will continue to spread from west to east overhead
tonight. Areas across northeast lower with longer efficient
radiational cooling with calm winds and mostly clear skies will have
the best chance of seeing FG/BR development. Latest
observations/trends support APN having the best chance of seeing
VSBY reductions due to FG/BR late tonight/early Friday morning.
FG/BR will also be possible at PLN and CIU. Any FG/BR is expected to
dissipate quickly after sunrise, returning flight conditions to VFR
across all areas through Friday evening.
