.KEY MESSAGES...

- While dry weather has returned, clouds will be slow to move
  out tonight and Friday. Temperatures run near, then above
  seasonal normals for most of the forecast.

- A significant pattern change to much colder conditions appears
  increasingly likely late next week into the Nov 23-24 weekend.

.DISCUSSION...
Issued at 203 PM CST Thu Nov 14 2024

The Quad State is under the descending branch of a h50 jet
streak nosing into the Mid-Atlantic this afternoon. Sfc high
pressure is building in from the west at this time with a NW
wind filtering in drier air. Shallow moisture has been trapped
beneath a low lvl inversion seen on forecast soundings today
and resulting strato-cu doesn`t look to be in any hurry to move
out tonight. The forecast will maintain mostly cloudy skies
through the night. The best chance of clearing will be across
portions of SEMO. Any areas that see clearing may see dense fog
development. Albeit northerly flow overnight, overcast skies
will keep temperatures above normal with lows in the upper 30`s
to mid 40`s.

Friday and the weekend will see an increasingly amplified
pattern aloft as a trof digs into the Rockies resulting in a
ridge axis across the eastern CONUS. A sfc high moves into the
central Appalachians resulting in sfc winds turning toward the
south and increasing temperatures this weekend. Near normal
temperatures on Friday will rise to above normal for Saturday
and especially Sunday with highs in the upper 60`s to near 70.

Looking into next week, an active pattern develops. Northern
stream energy is expected to quickly lift northward into the
Great Lakes with southern stream energy dipping into Baja and
then lifting through western Texas and eventually into the
central plains by late Monday. Strong height falls overspread
the plains resulting in a deep sfc reflection with a sfc low
dragging a cold front near and through the region on Tuesday.
This system will bring our next chance of rain with PoPs
increasing Monday night into Tuesday.

The bigger story with this system will be the evolving pattern
that takes shape as the aformentioned southern stream energy
phases with a northern stream disturbance moving across the
Canadian provinces. There remains a great deal of uncertainty
involving the eventual pattern which is reflected in cluster
analysis with a notable dipole in the h50 heights suggesting
not only timing uncertainty, but also uncertainty in the
amplitude of the trof/ridge pattern. There are still signs of a
much colder airmass diving out of Canada late in the week.
After above normal temperatures ahead of this system,
temperatures look to fall below normal, although just how much
below is still in question.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 521 PM CST Thu Nov 14 2024

Satellite imagery shows low stratus clouds scattering out in
the vicinity of the Mississippi River this evening with mostly
clear skies over most of SEMO. Across the rest of the region,
MVFR cigs remain in place between 1.5-3.0 kft AGL. The latest
trends indicate that clearing is taking place faster than what
is progged by most of the model guidance. While the current
forecast calls for a gradual return to VFR conditions across
all terminals during the day Friday, it is possible this occurs
much sooner, leading to lower than normal forecast confidence.
Northerly winds will be light between 3-6 kts.
