A trough of low pressure may be the trigger we need to generate a few storms across the Brazos Valley on Thursday afternoon. There is more moisture available in East Texas, which is where the rain chances will be higher.
As usual, the Brazos Valley is in the "transition zone". I think there may be enough moisture to justify at least a 30% chance of rain for Leon, Madison, Milam and Robertson counties. If any showers develop, they'll probably dissipate as they make their way through Bryan/College Station, with rain not likely south of the Twin Cities.
Something that we have yet to point out on-air is the latest run of our Pinpoint Forecast model, which is showing slightly better rain chances for Bryan/College Station between 3 - 7 p.m. After some additional analysis, we may bring the rain chances up a bit this afternoon -- but this is not likely.
If your curious, the rain deficit is only growing with the lack of precipitation across the Brazos Valley. As of the end of July, Bryan/College Station is over five and a half inches below average for rain.
