.PREV DISCUSSION... /issued 640 PM CDT Sat Apr 21 2018/

AVIATION...
22/00Z TAFs. Mainly IFR conditions first half of the forecast with
improving conditions after 12Z from west to east as storm system
moves east and drier air moves in. Areas of drizzle/showers
mainly through this evening and even a little past midnight
around KOKC up through KPNC. As surface low moves southeast of
terminals and surface ridge moves in, north-northwest winds will
increase toward and after daybreak.

PREV DISCUSSION... /issued 242 PM CDT Sat Apr 21 2018/

DISCUSSION...
Area of rain and isolated thunderstorms will continue to move
east/northeast across the area the rest of this afternoon and
tonight. Rain chances will end from west to east across the area
this evening and overnight as the upper low moves east over the
region. Clouds will stick around across a good portion of the fa
tonight before beginning to clear out from west to east Sunday as
the upper low moves east of the region.

Models show a mid and upper level system moving across the
Northern and Central Plains early next week pushing a cold front
across the area Tuesday. This system will also bring another
chance for showers and thunderstorms to portions of the fa.

Models differ for at least the latter half of next week which will
affect when/where another chance for showers and thunderstorms
will be but right now have rain chances again Thursday and Friday.
Another cold front could also move across the region sometime
Thursday.

Temperatures are expected to remain at or below normal for this
time of year the rest of this weekend through much of next week.
Highs will generally be in the 60s and 70s for the work week with
lows in the 40s.

With rain chances, cooler than normal temperatures, and min RH
remaining above 25 percent, fire weather conditions are currently
expected to remain low through much of next week.
