.PREV DISCUSSION... /Issued 858 PM CST Thu Nov 23 2017/

DISCUSSION...
Patchy thick cirrus continues to rotate around a strong mid-level
anticyclone centered just west of Baja CA this evening. Leading
edge of clouds just starting to make it into northeast OK and
should continue moving south and east overnight into midday
Friday. Dry air at the surface and mostly clear skies has allowed
temps to cool quickly this evening so updated grids earlier to
catch those spots already nearing overnight lows and to adjust
sky cover some.

Light southerly winds will continue tonight and strengthen Friday
as pressures fall across the High Plains ahead of approaching
shortwave energy. Warmer air aloft spreads east during the day
which will aid a modest warmup into the lower 70s across parts of
eastern OK with 65 to 70 for northwest AR. Occasionally breezy
winds and RHs in the 25-35 percent range will result in some
limited fire weather potential for east central and northeast
Oklahoma during the afternoon.
