Interesting thoughts from NWSFWD
Saturday onward
An arctic cold front will arrive early Saturday morning, ushering
in much colder temperatures that will linger through the rest of
the weekend and into the early parts of next week. Highs on
Saturday will likely occur early in the morning across North
Texas, and mid to late morning across Central Texas. Descending
temperatures can be expected through the day, along with windy
conditions during and several hours after the cold front. All rain
chances will remain east of I-35, where the better moisture will
reside. By Sunday, some locations, especially those west of I-35
and north of I-20, may struggle to get out of the 30s in the
afternoon. Fortunately, it appears as if the precipitation will
remain across Central Texas, where temperatures will be safely
above freezing.
The cold temperatures will linger into the next work week with
the cold dense air mass in place. Some models have hinted that
there may be some moisture to work with by the end of this week
and into the next, but it is important to note that confidence in
the 6-7 day time scale is very low. Raw model output and
precipitation type algorithms do have their flaws, and many images
have already been making their rounds in the internet. Models
will continue to flip-flop in the coming days, and given the
probability of no wintry precipitation is much higher than that of
any wintry precipitation, will continue to advertise a dry
forecast where temperatures are at or near freezing.
