.DISCUSSION...
Overnight, patchy fog may develop across southeastern and
south central Oklahoma where the wind will remain light
overnight. Low pressure will deepen across eastern Colorado on
Sunday, which will result in moisture return from southern and
central Texas. A rather windy day is expected which will increase
fire weather concerns, especially northwestern Oklahoma. Drier air
may remain through the afternoon which will result in afternoon
humidity between 25-30 percent, perhaps lower. A fire weather
watch will be issued for a few counties in northwest Oklahoma.

At this time, it appears that rather warm 85h temperatures will
keep elevated convection chances rather low Sunday into Monday. Most of the precipitation will be east and south of the area
Wednesday night into Thursday. The exception may be south
central and southeastern Oklahoma.

A dryline will push to around Highway 81 Monday afternoon, perhaps
farther east. A rather narrow axis of higher instability is
expected along and just east of the dryline Monday afternoon.
Surface/boundary layer convection will likely remained capped
through the afternoon.

Better chances or rain and elevated storms will arrive Monday night
into Tuesday as a western trough approaches. This should also
coincide with a few embedded disturbances moving through
increasing southwest flow aloft.

Additional rain and some storms may develop along a cold front which
is expected to move across most of western and central Oklahoma
during the day Tuesday. As colder air filters into the state
behind the front, there may be an opportunity for rain to change
to freezing rain across central and south central Oklahoma late
Tuesday into Wednesday.

Rain chances will increase again by Friday of next week as
another trough develops/moves across the western United States.
