.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
The main change to the TAFs since the 00Z forecast issuance was
the addition of LLWS mention at all sites. Strong northerly winds
are noted in the WSR-88D VAD wind profiles right off the deck,
and with winds going light or calm with the boundary layer
decoupling, it is now meeting LLWS criteria. Otherwise, VFR
conditions will prevail with light winds thru the TAF period.

PREV DISCUSSION... /Issued 322 PM CST Sat Nov 18 2017/

DISCUSSION...
Winds have begun to slowly diminish as strongest pressure rises
move eastward and current wind advisory will be allowed to
expire. Sfc high pressure settles over the region on Sunday
providing a pleasant day.

Southerly winds increase on Monday and become gusty during the
afternoon which will raise fire weather concerns. The next cold
front passes early Tuesday but is expected to remain dry.
Thereafter the pattern aloft amplifies leaving dry northwesterly
flow through the Plains. Above normal temps look likely for late
week with the next cold front arriving next weekend.
