forecast looks good. Did make some adjustments to sky cover to

clouds moving into NW parts of the fa this afternoon. Otherwise,
no other changes.

.PREV DISCUSSION... /issued 628 AM CDT Sun May 21 2017/

AVIATION...
21/12Z TAFs. VFR conditions expected to prevail with light and
variable winds becoming south/southeast through the day and stay
on the light side. RA and TSRA across northern Texas expected to
stay well south of KSPS.

PREV DISCUSSION... /issued 359 AM CDT Sun May 21 2017/

DISCUSSION...
Scattered showers and storms expected to stay just south of our
CWA this morning as mid-level/H7 trough continues to progress
eastward over region. Another great May weather day with light
winds and low RH in store, and here we are on midnight shifts.

Rain chances will increase across mainly northwest Oklahoma
tonight as next s/wv trough progresses through base of
northern/central U.S. l/wv trough. Rain chances will continue
through at least Tuesday morning as moisture returns and height
falls continue as trough progresses through region. Cold front
will move through the area late Monday and early Tuesday which
will help focus rain chances. Severe weather cannot be ruled out
late Monday ahead of and near this front, especially over far
western parts of Oklahoma and western north Texas as possible MCS
progresses off of High Plains. Primary impact would be damaging
winds.

Continued cooler than average through Wednesday before temps
closer to average and above return Friday into next weekend.
Models trying to converge on a pattern for multi-day severe
weather toward next weekend given moisture return, dryline/cold
front proximity and modest w/sw flow.
