An isolated shower or thunderstorm is possible overnight. The best chance
will be along and north of the Red River and west of Vernon and Seymour.
If storms develop, they may be strong to severe with large hail and high
winds being the main concern. Lows in the mid 70s with partly cloudy skies.
Southeast wind 15-20 mph.
Partly cloudy, hot, and breezy. Highs in the mid 90s, upper 90s to low 100s
west of I-44. Heat index values will likely climb above 100°F in many locations.
South/southeast winds 15-25 mph.
An upper level ridge of high pressure will slide over Texoma Sunday through Tuesday.
This will allow for hot, dry, breezy conditions to take hold. There are indications
that late Tuesday night, this ridge will break down and allow for an upper-level
low pressure center to move across Oklahoma and north Texas. This may bring a chance
for night-time thunderstorms Tuesday night and Wednesday night.
