AREA FORECAST DISCUSSION

Issued at 119 PM CST SUN NOV 19 2017

A large surface ridge in place over the area underneath northwest
flow aloft will maintain cloud free skies and slightly cooler
than normal temperatures through the remainder of the afternoon
and evening. Light southwesterly winds will steadily increase
overnight and particularly Monday late morning and afternoon as a
lee-side surface low matures across southern Canada. This will
moderate temps to the mid 30s across the area tonight, with a more
notable increase expected Monday. By Monday afternoon, wind gusts
could range from 25 to 30 mph, which will help to push afternoon
highs up slightly from Sunday. Generally expecting to see temps in
the upper 50s to low 60s across the area at that time, with
Monday night lows only dipping into the upper 30s to low 40s.

The brief warming trend will come to a halt Tuesday as the surface
low to the north forms a cold front, which will then push through
the local area Tuesday afternoon. A building upper-level ridge to
the west will block deep layer moisture ahead of the front, thus not
anticipating any precip as the boundary pushes through the region.
Below normal temps behind the front are expected both Tuesday and
Wednesday, until warm advection returns on Thursday. Tuesday night
temps will drop to the upper teens to low 20s across northern
Missouri, and low to mid 20s elsewhere. Locally speaking,
Thanksgiving Day looks to be seasonal with afternoon highs peaking
in the mid 50s for most of the area, and low 50s across
northeastern Missouri. Travelers in the surrounding area should
have no weather concerns through the holiday weekend as dry
conditions will continue as the ridge axis to the west stalls and
eventually forms a blocking pattern.

A few passing but very thin, high-based clouds will result in the
continuation of VFR conditions through the forecast period. South
southwest winds will remain sustained at around 11-12 kts through
sunrise, then will increase to sustained speeds between 15-20 kts
with occasional gusts to 30 kts from late morning through late
afternoon. Low-level turbulence or sub-criteria LLWS remains
possible before gustiness increases after sunrise, but consistent
direction and gradual speed increases should prevent a TAF mention
from being warranted.
