/12Z TAFS/

Patchy dense fog continues to drop visibility to MVFR conditions
across the eastern terminals this morning, with an occasional drop
to IFR possible as well. These should continue through mid morning
before the fog dissipates and VFR conditions return. The VFR
conditions and light southerly winds will continue through this
evening, before another weak cold front shifts winds around to the
north late tonight and into Friday morning.

(Today and Tonight)

Skies have cleared across West Central Texas early this morning, 
with temperatures falling into the low to mid 40s in most areas. 
Temperature/dewpoint spread has dropped to just a degree or two in 
most locations, and fog has started to develop in a few areas. Have 
added a mention of patchy fog into portions of the eastern Big 
Country, Heartland, and Hill Country. Fog won't last long in those 
areas where it develops, with abundant sunshine allowing 
temperatures to soar into the upper 70s and lower 80s this 
afternoon. Lows tonight will fall into the upper 40s to around the 
50 degree mark. The latest TTU-WRF is showing an area of showers and 
storms developing across Oklahoma this evening and dropping 
southeast across the Red River. Models suggest it should dissipate 
about the time it reaches the northern Big Country so will leave out 
of the forecast for tonight, but will be worth watching.

(Friday through Thursday)

Following the cold frontal passage to begin the period on Friday
morning, temperatures will be below normal in the upper 70s.
However, temperatures will warm up more over the next couple of
days with dry conditions in place. This will leave a rather nice
weekend ahead with temperatures in the mid 80s. 

Afterwards, changes are coming with regards to the forecast as an
upper level disturbance approaches from the west. Models continue
to disagree with the positioning of the system. However,
additional embedded disturbances will help to keep rain chances 
in the forecast despite those uncertainties. Rain chances are 
included from Monday morning on, but chances still remain fairly 
low. At this point, there is a possibility for severe weather 
given the current set up. However, details are scarce due to the 
uncertainty at this time. So, please check back for the latest 
updates as they become available.
