CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
Patchy light drizzle/fog will continue this morning across

during the day with clearing skies from north to south this
evening into the overnight hours. Any areas that clear will
have the potential for patchy dense fog to develop given the
recent rainfall/light winds.

DISCUSSION...
Upper low is now over southwest Missouri with low clouds and areas
of drizzle or fog over eastern Oklahoma and western Arkansas.
Latest surface analysis showed low over southwest AR with cold
front extending south of the DFW area into far west TX. Heavy
rains have come to an end, but a widespread 1-4" fell across the
area, with localized higher amounts to 5+ inches. This has
caused numerous rivers to rise to flood levels and several
flood warnings are in effect.

Low clouds are expected to persist today under cyclonic flow with
wrap-around light precip. This will keep temperatures quite cool,
with little recovery expected. Clouds will eventually break up
beginning tonight and areas of fog are possible by Sunday morning
given light flow and abundant low level moisture. Lows Sunday
morning will dip into the 30s and 40s.

Winds pick up Sunday afternoon into Monday as lee side trough
develops ahead of next upper wave. Should stay dry until late
Tuesday into Wednesday when next front arrives. Active pattern
until the end of next week including the potential for severe
weather and heavy rain Friday.
