Area Forecast Discussion
National Weather Service Lubbock TX
1015 PM CST Thu Jan 11 2018

.AVIATION...
Few changes with VFR, dry, and light winds dominating the next 12
hours or so. Surface high pressure ridge over the Panhandle and
South Plains late this evening gradually edging east with more
influence from next version of surface lee-side low pressure trough,
especially during the day Friday. Surface flow may approach 15
knots by midday at both KLBB and KPVW though majority of guidance
holds speeds just shy. Will hold onto the slightly lower wind
speeds this forecast and let next shift reassess. RMcQueen

AVIATION...
VFR dry airmass with light northerly winds transitioning eventually
to southerly late Friday - as surface ridge to the east is replaced
by surface troughing just to the west. RMcQueen

PREV DISCUSSION... /issued 218 PM CST Thu Jan 11 2018/

DISCUSSION...
Wind speeds are slowly decreasing as the surface pressure gradient
is slowly weakening. The advisory is on target for its expiration
at 3 PM. Otherwise, things are looking much quieter for a while
with models are persistent with a return to a western ridge and
eastern trough upper pattern over the continental U.S. This
continues to look like a dry pattern with any little ripples just
downstream from the upper ridge looking far too weak to interact
with limited moisture. Of more important note is the potential for
a brief shot of cold air for Tuesday with highs that day currently
looking to only reach the 30s. This occurs as a large low forms
over the Great Lakes while ridging remains over the intermountain
West. The bulk of the cold air will be directed well to our east,
but again the potential exists for the western piece of cold air
to backdoor into the forecast area.
