.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.

Light and variable winds through 15-16Z before becoming more
southerly as surface return flow sets up. A slight wave in
generally zonal flow will allow mid-level clouds to increase
through the day Sunday. As wave moves through late in the period,
a few light showers cannot be ruled out across southeast OK and
western AR.

.PREV DISCUSSION... /Issued 342 PM CST Sat Feb 25 2017/

DISCUSSION...
It`s been a beautiful late winter day across the area...with below
normal temperatures for a change. Active weather remains north
and east...with strong upper storm system forcing a severe line of
thunderstorms across the mid-Atlantic states this afternoon.

We will remain within zonal flow in the upper levels through
Sunday...with a weak wave arriving by Sunday evening into Monday.
There may be enough moisture for a few light showers or sprinkles
Sunday night with the better chance for precipitation across
southeast Oklahoma and western Arkansas. Sustained southerly winds
and increasing moisture on Monday will result in highs in the mid
60s despite the increase in clouds and possible precipitation.
Tuesday will be the warmest day of the week ahead of cold front
arriving by early Wednesday morning. This will also raise fire
weather concerns with increasing winds on Tuesday afternoon.

Increased large scale ascent associated with approaching upper
wave combined with forcing along and ahead of the front will
likely support a line of showers and thunderstorms late Tuesday
night. Given strong wind fields and instability, some of these
storms could pose a threat for severe wind or hail.

Quiet weather is expected for the rest of the week...with
temperatures running just at or slightly above normal.
