Storms Here and There, but Rain Odds Less than Even Money
5:00 pm Tue 22 May 2018
Only a few thunderstorms popped up in Texoma today, primarily east of Highway 75 underneath a very weak upper trough. Less than 10 percent of the area got rain.
Expect a partly cloudy to mostly clear night with lows in the mid to upper 60s- much like last night.
Wednesday and Thursday see somewhat better chances for a few heat-driven afternoon thunderstorms in the 30 percent range; winds continue very light at 5 to 10 mph from the southeast.
The computer models are in good agreement that an upper high will build northward this weekend, making it plenty hot with highs in the low to mid 90s. Two very weak disturbances coming over the top of the highs could fire off a few thunderstorms all the way through Saturday, but prospects for rain will be diminishing with the weekend mostly dry and quite toasty.
There’s good agreement between the models on the evolution of a surface low pressure area over the Gulf, and it moving northward Sunday before stalling over Louisiana. This could cause serious flooding to our east, but leave Texoma in a dry northerly wind flow Sunday into next week.
This bears watching as always, but the position of the upper high suggests Texoma is not threatened by this system. On the other hand, areas from Louisiana to Florida may have a very soggy Holiday weekend as they will be on the moist side of the low.
