Area Forecast Discussion

.DISCUSSION...
The 12Z aviation discussion follows....

&&

.AVIATION...
Light and variable winds will turn more southerly, and increase to
about 10 to 15 kt this morning, as surface high pressure begins to
shift toward the east. The pressure gradient will continue to
tighten into the night, which should maintain these wind speeds
through early Thursday morning.

No ceilings or visibility restrictions are expected.

.PREV DISCUSSION... /issued 316 AM CST Wed Jan 17 2018/

DISCUSSION...
After another cold start to the day, today will begin a steep
warming trend that will culminate on Saturday with temperatures
rising to about 20 degrees F above the seasonal average (as
compared with about 25 to 30 degrees F below the average over the
last couple of days). Winds will also increase as surface low
pressure to our west replaces the cold high pressure that has
been centered over Oklahoma and vicinity recently.

Moisture sufficient for rain will arrive this weekend. There may
be a few showers in the warm air advection well in advance of the
next system (Saturday), but the main rain potential will be on
Sunday. The eastern half or so of our forecast area will have a
chance of rain on Sunday, and isolated thunderstorms will also be
a possibility. Light rain (possibly mixing with snow at times) may
also occurr in far northwest Oklahoma on Sunday.

A cold front will sweep east across Oklahoma and north Texas on
Sunday, bringing Pacific "cold" air into the region. While cooler
than the well-above average readings of Saturday, it will not be
nearly as cold as yesterday and this morning.

Moderately cool and dry weather will fill out the remainder of the
forecast period (into early next week).
