.DISCUSSION...
Issued at 135 PM CST Mon Dec 29 2025

Quiet weather today after a busy Sunday. We`re seeing gradually
clearing skies with northerly winds relaxing toward the
afternoon. Satellite shows the upper-level trough spinning over
the Great Lakes region with a ridge built up over the northern
Rockies. Amplified meridional flow on the east side of this
ridge has continued to stream cool northerly air into the
Central Plains with highs today staying in the 20s.

Good news for those who dislike this cold, temperatures are
forecast to rebound tomorrow as the Canadian High slides south
over Texas shifting flow back to southwesterly across the
region. This combined with building heights as western ridge
expands eastward will help to bring temperatures back up into
the mid 30s to mid 40s for highs on Tuesday, warmest across our
southwestern counties and cooler over northeast Missouri. This
ridge will keep temperatures fairly close to normal through
Wednesday.

Thursday a strong jet streak pushes south into the Great Lakes
region helping to push the cooler air back south into northern
portions of Kansas and Missouri. A frontal boundary will drop
south to around I-70 before stalling, bringing cooler
temperatures along and north and keeping the milder
temperatures for our southern counties. This cooler air again
won`t stick around for long as the trough over the Great Lakes
shifts eastward allowing ridging to our west to again expand
eastward leading to building heights. This will push the
stationary front back north and bring warmer temperature back
north on Friday with highs back in the upper 30s to mid 40s
along and north of I-70 while areas south approach 50 degrees.

Going into the weekend we see the breakdown of the western
ridge, deamplifying and expanding eastward. We see a surface low
develop over northern Texas and track eastward into Arkansas
Friday into Saturday, but precip from this system looks likely
to stay well south of our area. This means quiet, dry weather
continues. Ensembles have temperatures trending even warmer
Sunday and Monday with highs back in the upper 40s to mid 50s.
