DISCUSSION...
Overall, a dry, northwest flow pattern will continue through the
forecast period. Elevated to near critical fire weather conditions
is the primary forecast issue into next week.

For tonight, the coldest night so far this season is expected.
Trended toward the colder end of guidance based on the low dew
points, light winds, and mostly clear skies (for most locations).
Slightly warmer temperatures are expected across northwest
Oklahoma, where clouds and winds may increase toward morning.

A gradual warming trend is expected for Friday and Saturday
afternoons. Westerly, downslope flow will result in even warmer
temperatures by Sunday afternoon. High temperatures will be above
average, generally in the low to mid-60Fs. Fire weather conditions
may become near critical with very low relative humidity and warm
temperatures.

Another cold front will pass by on Monday. The Southern Plains
will be on the western edge of the cold air mass behind this
front. As a result, Tuesday afternoon appears to have the
greatest uncertainty for temperatures with the highest standard
deviation among guidance.

Warmer weather is expected to return by Wednesday before another
cool down for Thursday.
