.DISCUSSION...
Issued at 316 AM CST Thu Nov 21 2024

Quiet, yet breezy, conditions continue across the region, with
latest observations showing northwesterly gusts between 25 to 35 MPH
and temperatures in the 20s. Wind chills have also begun to plummet,
resulting in values in the teens to single digits.

As alluded to in the previous discussion, expect upper level ridging
to build across the Plains today, allowing the SPG to gradually
weaken. Nonetheless, will still see gusts between 20 to 30 MPH
persist for much of the day under a lingering stratus deck,
especially in areas east of I-29. Thus, only have highs rising into
the low to mid 30s, the coldest occurring north of I-90 in areas of
higher elevation.

Should see more clearing overnight, with winds progged to become
light and variable. While some patchy fog may certainly be possible
given the recent moisture in place, think the bigger impact will be
overnight lows falling into teens with the aid of efficient
radiational cooling. That being said, should see temperatures
rebound into the mid 30s to 40 by Friday afternoon under partly
cloudy skies.

Upper level ridging amplifies across the central CONUS this weekend,
keeping conditions dry and cool across our area. Still seeing decent
agreement in guidance that a moisture starved cold front will dive
across the Dakotas Saturday night into Sunday, causing southeasterly
winds to turn northwesterly in the wake of FROPA. Do have gusts
increasing to 20 to 35 MPH along and west of I-29 during this time,
the strongest occurring west of the James River Valley.

Temperatures flip back below normal early next week as upper
troughing deepens and moves into the Great Lakes.  Stronger
northwesterly winds and cold advection aloft results in highs in the
20s to lower 30s for much of the new week. Taking a peek ahead in
the forecast suggests that we may trend towards a more progressive
zonal flow pattern into Thanksgiving. This type of pattern can bring
greater potential for more frequent, fast moving waves with rather
poor predictability, through the Plains.

.AVIATION /12Z TAFS THROUGH 12Z FRIDAY/...
Issued at 536 AM CST Thu Nov 21 2024

Breezy northwesterly winds continue across the region, with latest
satellite imagery showing a lingering stratus deck across much of
our area. As a result, have cigs ranging between MVFR to VFR levels,
with isolated pockets of IFR across southwest Minnesota. Guidance
continues to hang onto the stratus for much of the morning, thus,
wouldn`t anticipate seeing widespread return to VFR until at least
this afternoon. Gusts during this time look to range between 20 to
30 MPH, the strongest occurring east of I-29. Otherwise, look for
winds to quickly diminish through the evening, allowing light and
variable winds to prevail overnight.
