.PREV DISCUSSION... /issued 345 AM CST Fri Jan 12 2018/

DISCUSSION...
After a windy last couple of days, we will have a reprieve from
the strong winds for at least the next four days. We will remain
under northwesterly flow aloft through the weekend and we will
see a quick return to southerly surface flow this afternoon. This
will help to erode the cold airmass that arrived yesterday across
the Caprock where highs should climb into the low 60s while the
Rolling Plains will hang on to the cold airmass a bit longer and
remain in the upper 40s to lower 50s. Another cold front will push
over the area Saturday dropping highs back into the upper 30s to
mid 40s as easterly flow pulls cold air into the region through
the day.

As the front arrives Saturday, a strong wave will deepen through
the weekend across the northern U.S. eventually becoming a closed
low as it swings out across the Great Lakes by Monday. This will
help dislodge another stronger cold front expected to arrive in
our region sometime Monday, likely in the latter half of the
daytime hours. Ahead of the front, southerly boundary layer flow
will attempt to pull some low-level moisture back into the region
but this will likely be limited to the southern Rolling Plains and
not enough to generate any precipitation. Highs Monday will
depend on when the front arrives but we could see a strong
gradient with near 40 in our northern CWA to mid 50s across the
southern counties of our area. The models continue to keep the
strongest part of the cold airmass east of our area resulting in a
glancing blow but enough to keep highs from warming up too fast
through the end of next week. Tuesday will be the coldest day
with highs in the mid 30s across the Rolling Plains with near 40
along the TX/NM state line with highs climbing 5-10 degrees each
day through Friday of next week.
