Spotty turns to scattered: Showers and storms likely this weekend

By  | 

BRYAN, Tex. (KBTX) - I've spent most of my afternoons this week watching storms form on the horizon, come painfully close, then sputter out just in time to not leave a drop on my front lawn.

All I've been left with is a sweaty brow and a crunch beneath my feet as I walk on my yard.

Time to start watering? Probably ( more like a couple weeks ago), but I'm willing to wait another couple days before breaking out the water hose.

In addition to high pressure backing off just a tad, we'll get another dose of moisture to work with to enhance our storm coverage in the afternoons.

No doubt it's been humid at the surface. Just step outside at 2pm and you'll know that. We'll actually get some deeper upper level moisture to work with this weekend, especially on Sunday.

What was once Tropical Depression 4 (originated in the open Atlantic) and its remaining tropical "juice" will continue to migrate our way over the next couple days, giving us a little more fuel to work with in terms of afternoon storm development.

Above is a look at the total moisture available for storm development in the atmosphere. Our best chance for widespread rain and storms will likely follow the greatest amount of available moisture, which looks to be Sunday. Some of this moisture will hang around to leave chances for rain through next week, too.

Back to the weekend

Saturday looks to start much like the past several days: mild and muggy, then quickly hot and humid. We're expecting more cloud cover, and eventually, showers and storms will pop up. Coverage still isn't optimal for widespread rain at this point (around 40%), but there's enough of a chance for rain that you'll want to bring some rain gear along with the water and sunscreen.

Sunday should be our best chance for widespread showers and storms. Showers will be possible in the morning, but once again look more likely any time after midday. Increased clouds and the chance for rain should also keep temps down to the low 90s with heat index right around 100 if you're not seeing rain.

Bottom line: You'll want to have the rain gear just in case this weekend. Thunderstorms could drop a quick 1 to 2 inches for some, but most will likely get less than an inch. The main threats with storms will be for cloud to ground lightning, gusty winds, and locally heavy rain.

Our daily chance for scattered storms looks to continue at least a couple days into next week as tropical moisture hangs around the area. Keep up to date with the forecast on Twitter, Facebook, and always on your News3 app!
