some sprinkles/showers... currently in North Texas... could move
north into parts of Oklahoma this morning. Otherwise... upper high
pressure center will build west over the next few days... although
models disagree how far west. This high pressure along with an upper
trough in the western U.S. Will lead to southwest flow over or just
west of the forecast area. Depending on where this sets up... there could be a
chance for showers/storms in northwest/western parts of the County Warning Area.
However... right now expect rain to remain west and northwest of the
forecast area until the weekend.

Most locations will likely experience hot temperatures and breezy
south to southwesterly winds over at least the next several days as
the pressure gradient tightens.

Models show the high pressure center shifting east over the weekend
which could lead to a better chance of southwest flow over at least
part of the area. With the southwest flow aloft and a possible
frontal boundary in or near the forecast area... there will be more of an
opportunity for showers and thunderstorms across at least northwest
parts of the area late this weekend into early next week. Models
then show a trough moving into the central U.S. With a front moving
into the area towards the middle of next week which will continue a
chance for showers and thunderstorms across parts of the forecast area.
