Area Forecast Discussion
National Weather Service Tulsa OK
1142 PM CDT Sun May 20 2018

.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
Conditions are trending downward with regard to visibility and
ceiling with highly variable flight impacts expected through the
night. Generally expecting a mix of lower ceilings and areas of
dense fog to develop for most locations with far NW AR sites
especially prone. Conditions will improve after sunrise with VFR
expected by late morning at all sites.

.PREV DISCUSSION... /Issued 811 PM CDT Sun May 20 2018/

DISCUSSION...
Have lowered pops to reflect downward trend in convection. What
remained in the severe thunderstorm watch was allowed to expire at
01z. Will keep low pops going through midnight across the eastern
zones as some convection lingers in that area. Otherwise, the rest
of the first period forecast elements will be left as they are at
this time.

Updated ZFP/PFM/AFM already sent.
