Tuesday Afternoon Update

From Chief Meteorologist Brandon Rector...

Showers and thunderstorms developed across portions of the Big Country once again today. Those affected by the rain likely received about a quarter to half an inch, but it was possible for some to see one inch or more. Highs were mainly in the 80s due to the cloud cover and rain. Our southeastern communities, however, reached the low 90s due to a lack of rain moving through that part of the area.

Good rain chances are going to be sticking with us through the end of the work week. We will have plenty of moisture remaining in place. Instability will be supplied by the heating of the day. There should be not one, not two, but three possible lifting mechanisms around the area. One is outflow boundaries from any thunderstorm activity that develops. Two is a stationary front to our north around the Red River. It is expected to move southward towards our area and hang out. Last, but not least, is upper level disturbances sent our direction thanks to a weak upper level low that is well west of us. Our biggest threat from any showers or thunderstorms that develop will be heavy rain. It will be possible to pick up a quick quarter to half an inch with isolated higher amounts depending on the strength of the storm. This could lead to ponding on the roadways and minor flooding of low-lying areas. Be careful if you are going to be out and about. Highs during this time period should be in the mid to upper 80s.

Some isolated showers and thunderstorms will still be possible on Saturday, but the chance is only 20%. Highs look to be in the upper 80s to low 90s.

A shift in the weather pattern is expected to take place by the second half of the weekend and early next week. The upper level high pressure ridge that has been to our west most of the summer may shift into the southern plains. This would increase our temperatures and bring our rain chances down to less than slight. For now, highs look to be in the low to mid 90s Sunday through next Tuesday.

Have a wonderful Wednesday!
