DISCUSSION...
Drier air continues to slowly filter northeast Oklahoma early
this morning behind cold front with unseasonably cool conditions.
Temperatures have dropped off into the upper 50s in a few
locations across northeast Oklahoma and northwest Arkansas.

Moist ground conditions from the recent rainfall has lead to
patchy fog development across portions of east-central Oklahoma
and northwest Arkansas. A dense fog advisory may be required in
aforementioned area if fog becomes more widespread than currently
anticipated. Visibilities will quickly improve shortly after
sunrise as northerly winds begin to increase. Dry/mild weather
forecast for this afternoon as surface high pressure settles over
region under mostly sunny skies.

Southerly winds will begin to develop on Monday as surface high
begins to shift east. This will allow low level moisture to surge
back north into the region Monday afternoon into Monday night with
a chance for scattered showers/thunderstorms as warm front lifts
north. Precipitation chances will continue on Tuesday as a weak
upper level impulse moves out of western Texas. Could see locally
heavy rainfall as precipitable water values approach 2.0 inches
in a few areas.

Warmer conditions expected on Wednesday ahead of a weak cool
front which will move into the area on Thursday. Front will stall
by friday with a continued chance for scattered showers/thunderstorms
into the weekend. Mostly cloudy conditions should keep high
temperatures a few degrees below normal...especially north of
stalled boundary.
