625 PM CDT Sun Oct 7 2018

.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
Scattered storms continue across southeast OK this evening, but
high-res model solutions show this activity waning over next few
hours. Convective potential should become more closely tied to
retreating warm front located from SW-NC OK. Highest probability
of any storm impacts at TAF sites will be at the NE OK locations
through about 10z and at KMLC through 03z, with MVFR conditions
becoming more prevalent across eastern OK tonight. South winds
will increase late Monday morning with all areas trending back to
VFR conditions.

.PREV DISCUSSION... /Issued 352 PM CDT Sun Oct 7 2018/

DISCUSSION...
Surface warm front has lifted north across northeast Oklahoma once
again, with gusty south winds at Tulsa and dewpoints back in the
low 70s across much of the area. A couple storms which developed
across far eastern Oklahoma earlier have taken full advantage of
the rich moisture and favorably sheared environment. These storms
have had a history of low level rotation, with the last one moving
through Benton County now. Any new storms within this zone will
have to be monitored. With the boundary lifting north, there
won't be as much low level confluence to support new storms, but
there are storms across north Texas and southeast Oklahoma within
an axis of warm advection that will continue through the late
afternoon and evening. There should be overall less coverage of
storms this evening, with decreasing chances after midnight.
Storms currently across southwest Oklahoma will likely affect
areas north and west of I-44 through tonight.

Another warm day is expected Monday, depending on how much cloud
cover there is. The best chances for rain remain across western
and central portions of Oklahoma, with dry weather across
Arkansas.

Upper trough will finally move out into the Plains on Tuesday,
which will force a significant cold front through by Wednesday
morning. The moist airmass in place combined with strengthening
winds aloft will bring a chance for severe weather on Tuesday in
addition to heavy rain. The highest potential for flooding will
generally be north and west of Interstate 44, where the heaviest
rain will fall tonight and then again on Tuesday. The good news is
the system is progressive so flooding impacts are less likely
across southeast Oklahoma and western Arkansas given the current
forecasts.

Much cooler temperatures are expected in the Wed-Fri period, with
lows in the 40s and 50s and highs in the 60s. It will finally
start to feel like fall!
