.KEY MESSAGES...

- Our stretch of cloudy and occasionally rainy/drizzly conditions
  will end by this evening in the wake of a passing cool front.

- Temperatures will be cooler than average over the next few
  days, especially Friday night when lows are expected to dip
  below freezing, before moderating by early next week.

.SHORT TERM /THROUGH FRIDAY NIGHT/...
Issued at 1233 PM CST Thu Nov 5 2026

We will continue to see cloudy and occasionally rainy/drizzly
conditions this afternoon into the evening hours today as a cool
front and associated mid-level PVA maxima will gradually translate
through the area. Ample low-level moisture per the HRRR/RAP/RRFS
soundings up to around 8000 feet AGL should support occasional light
drizzle or showers at times.

In the wake of the front, drier air is progged to filter in, but
there are some questions on just how quickly the cloud cover will
dissipate. We`ve leaned a bit more pessimistic compared to the NBM
which has us gradually clearing out by tonight, but with a stout
thermal inversion in place, and plenty of lingering low-level
moisture, will keep a cloudy overnight forecast. With northerly
flow/cold air advection behind the front, tonight`s lows should dip
to the middle to upper 30s for most locations.

The dry air looks to finally win out on Friday as an area of high
pressure builds into the region. A lobe of enhanced vorticity is
progged to move through lower Michigan, but it should remain far
enough away that it won`t generally any weather impacts for us. If
it does shift more westward, we may see a bit more cloud cover than
currently expected. It will feel a bit cooler Friday compared to
today, with highs warming only to the upper 40s. As the high
pressure center settles over the region, light winds and mostly
clear skies will result in a chilly night Friday night/Saturday
morning with lows dipping to the middle to upper 20s - temperatures
we haven`t experienced since the morning of October 17th! Bundle up
if you`re planning to be out and about Friday night!

.LONG TERM /SATURDAY THROUGH THURSDAY/...
Issued at 1233 PM CST Thu Nov 5 2026

After a chilly Saturday morning, temperatures will gradually warm
into early next week, along with dry conditions through mid-week
next week. The aforementioned high pressure system will remain
anchored over the central CONUS, along with amplified upper-level
ridging over the Intermountain West states. This should support a
period of quiet, pleasant fall weather. By Monday, high temperatures
are forecast to rise to the middle 60s, which would be nearly 10
degrees above average for this time of the year.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 425 PM CST Thu Nov 5 2026

Some brief low VFR cigs will be possible this evening, before
MVFR conditions upstream move back into the terminals.
Subsidence behind departing wave to promote the scattering out
of lower clouds as currently seen in southeast MN. Using
satellite and observational trends, the back edge of this MVFR
deck should arrive in eastern IA prior to sunrise, with
improvement to VFR at all terminals by 14z. Northerly winds to
remain under 12kts through the period.
