.PREV DISCUSSION... /Issued 903 PM CDT SAT AUG 20 2016/

DISCUSSION...
Much drier air continues to spread into the area behind a cold front,
which will result in temperatures falling well below seasonal
averages overnight. A few showers remain over far sern OK and west
central AR but they will gradually shift eastward with clearing skies
after midnight. Some patchy fog will likely form overnight but
confidence in dense fog not high right now as dry air filtering into
the region and sustained light wind not ideal for dense fog
formation.

Fair weather on Sunday as high pressure builds into the Southern
Plains and surface front stalls to our south. Front returns northward
as a warm front Monday/Monday night with increasing thunderstorm
chances as rich moisture returns with the front.

Minor adjustments were made to ongoing forecast based on current
trends in temperatures, dewpoints, and clouds. Updated forecast
products already issued.
