We've decided to increase your rain chances Tuesday afternoon and evening to 40%, as opposed to the 20% chances posted earlier this morning. Our typical, spring-time warm and humid airmass has set up across the region, as evident by the mostly cloudy and muggy conditions you've experienced the past few mornings.
Even though there's plenty of moisture in the Brazos Valley, we were missing a focus for storm development -- a cold font, warm front, dry line, etc. That scenario has changed a bit over the past few hours as a cold front has managed to push as far south as north central Texas! This front will likely turn stationary and won't bring us any cooler weather anytime soon, but storms will likely develop along this boundary. Since it's further south than earlier anticipated, any storms that develop along the boundary may hold together long enough to impact our north and western counties.
Rain chances for locations northwest of Bryan/College Station are now at 40% Tuesday afternoon and evening (which still means there's a better chance you won't get wet). Rain chances for Bryan/College Station and locations southeastward remain at 20%.
Also remember that any storms that do develop in Central Texas will have the potential of becoming severe, with large hail being the primary threat.
