AVIATION...
0Z TAFS - VFR conditions are expected throughout this TAF period
with increasing cirrus across portions of the area late tonight
into Tuesday. Strong, gusty winds are expected Tuesday with winds
shifting from the S to the W throughout the day. A cold front will
approach NW OK late in the current forecast TAF period but is
expected to remain just north of any TAF sites until after 0Z
Wednesday.

PREV DISCUSSION... /issued 338 PM CST Mon Jan 23 2017/

DISCUSSION...
Ridging over the south central part of the country will shift
eastward tonight into Tuesday. Meanwhile, a rather cold trough
along the West Coast will move across the Rockies and
northern/central Plains. This will bring rather gusty winds to
Oklahoma and north Texas, especially Tuesday afternoon during deep
mixing.

A Fire Weather Watch was issued earlier today for most of the
area along and west of Interstate 35. Although ERC (fuel) values
are near the 50 percentile, rather breezy/gusty winds will
combine with well above average temperatures and low
humidity. This should produce near critical to critical
fire weather conditions for much of western Oklahoma. The 85h
thermal ridge by mid afternoon Tuesday is expected to be mainly
east of Interstate 35, but close enough that part of central
Oklahoma may experience Red Flag conditions for a few hours.

Although frequent wind gusts over 40 mph are possible Tuesday
afternoon, a Wind Advisory will not be issued at this time. This
will also allow the Fire Weather Watch to be the main highlight on
the NWS national map.

A cold front will move across the southern Plains late Tuesday
afternoon and Tuesday night. This will usher in a period
of dry weather with near average temperatures that will last
through the upcoming weekend.
