DISCUSSION...

Northwest flow aloft prevails over the region today, on the
southwestern fringe of a broad upper trough centered over the
Great Lakes. Mid-level isentropic lift to our west is bringing
clouds and some showers and storms to the high Plains. A lot of
the mid cloudiness over our area has dissipated since sunrise,
likely due to increasing isentropic descent on the lower Plains.
With more insolation expected, highs should climb to the warmer
numbers the guidance has suggested. The best isentropic lift
should stay to our west and north thru the day today, thus no
precip is expected.

AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
VFR conditions will prevail through the entire TAF period
at all sites.

PREV DISCUSSION... /Issued 341 AM CDT Sun Jun 25 2017/

DISCUSSION...
An atypically dry low level airmass for late June will remain in
place for the next couple days before the inevitable return of
more typical humid air by the middle to latter part of the
upcoming week. A few showers and thunderstorms may brush parts of
far northeast Oklahoma and northwest Arkansas Monday night as the
tail end of a shortwave passing to the northeast clips this area,
and a weak surface boundary will be hanging around as well. The
better rain chances will come late Thursday night through Saturday
as a frontal boundary drops south into the area before stalling
and washing out by the latter part of next weekend.

Beginning about next Sunday, the summertime ridge looks to really
take hold, and the true summer heat and humidity will be here to
stay for a couple months most likely, so enjoy these next few days
of relatively pleasant weather as it will not last.

Stayed close to guidance temperatures the next couple days.
