247 AM CST Tue Jan 23 2018


Upper level flow has become zonal as the strong low moves over the
Great Lakes. Surface winds will lighter today as the pressure
gradient weakens. Surface lee troughing will develop Wednesday
with surface winds becoming southwesterly. A weak upper level low
will carve out of the ridge over southern New Mexico late
Wednesday then quickly move across the South Plains into Oklahoma
on Thursday. No precip is expected with this system, but it will
enhance winds some on Thursday and Friday. Zonal upper level flow
will continue Friday through early next week. There are still some
differences with the frontal passage this weekend. The GFS
continues to show a weak back door cold front early Saturday
though surface winds quickly return to the southwest by Sunday
afternoon. The ECMWF has a stronger cold front Saturday morning
pushing much drier air further south. Winds with this solution do
not return to the southwest until Monday. Highs on Saturday will
be about 10 degrees cooler than Friday but will slowly moderate
early next week.
