.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
Stratiform precip region of MCS over NTX continues to push southward
through far sern OK. Large anvil canopy continues across much of ern
OK/wrn AR but some thinning is noted in animated satellite imagery
across nern OK/nwrn AR. Expect layered mid/high clouds over TAF sites
to continue to thin areawide, allowing some light fog to form late
tonight where heavy rainfall occurred this evening. Highest chance of
fog at TAF sites is FYV/MLC/FSM. Otherwise, VFR conditions will
prevail through this period at all sites.

.PREV DISCUSSION... /Issued 924 PM CDT Sun Jul 23 2017/

DISCUSSION...
Convection that developed this afternoon along outflow/weak frontal
boundary has moved into far sern OK, nern TX, and swrn AR at this
time. Trailing stratiform precip lingers south of a MLC to Poteau
line, with embedded lightning in this activity. Expect this precip to
gradually dissipate/push SE of the area in the next few hours. Isolated
severe gusts and locally heavy rainfall up to 2.5" occurred with the
stronger storms this afternoon/evening. Most importantly, the
associated cold pool hammered the oppressive heat from north to south
today. Current temperatures are in the 70s to mid 80s! Some light
fog may develop late tonight where some of the heavier rain occurred
as clouds thin out overnight and wind goes light/calm. Forecasts
were updated earlier to adjust for these trends.
