OVERVIEW:

4-6 inches of rain will be possible across the Brazos Valley through Saturday evening as a slow-moving storm system moves across the state. There is a chance of showers and thunderstorms across the region through Saturday evening.

BLOG/UPDATES:

9:52 PM: Dense fog will be possible across the region Sunday morning. With all the rain we have received over the past two days, the wet grounds will lead to fog development. A cold front will move across the region Sunday morning, putting an end to any fog development after frontal passage.

6:35 PM All watches have been dropped for the Brazos Valley with the exception of a Flood Watch that is still in effect for Austin and Waller counties until 9pm Saturday. This will round out of severe weather coverage this evening as things clear out and sunny skies return for Sunday.

1:41 PM: The Tornado Watch has been canceled for Leon county.

1:19 PM: Our latest dewpoint map shows a dryline in west Texas. The dryline separates dry air behind it from moist air ahead of it. Once this boundary moves east of the region -- later tonight -- the chance of rain will end. Until then, with plenty of moisture still around, the threat of a few storms will continue.

Rodney Harris

1:04 PM: A FLASH FLOOD WARNING has been issued for Montgomery county until 2:45 p.m.

12:56 PM: Our latest analysis shows that much the precipitation has shifted southeast of Bryan/College Station. Walker, San Jacinto, Montgomery, Waller and Austin counties will continue to see some rain through at least 2 p.m.

I'm noticing a few showers that are trying to develop in Central Texas -- from near Waco down to Robertson county. The atmosphere over Bryan/College Station has become stable as a result of the earlier thunderstorms. However, new discrete thunderstorm development cannot be ruled out this afternoon, as the center of our storm system is still west of the region. The rain chances will remain in the forecast until this system moves east of us tonight.

7:39 AM: Showers and thunderstorms will continue to move across the Brazos Valley through at least noon today. Our biggest concern is for the threat of additional flash flooding. More rain -- in addition to the precipitation from Friday -- will run-off easily, which may cause potential travel problems in some locations.

The severe weather threat should be confined to small hail today, but isolated stronger storms can't be ruled out.
