Most impressive velocity signature of the day with some strong rotation not very far above the ground. It looks like it might have just missed Snook to the northwest. I would bet that there is at least a funnel cloud with this storm.

Getting reports of a possible tornado on the ground near Snook. It looks to be located 5 miles southwest of KCLL moving northeast around 10-15mph. If it remains on the ground it will likely come very close to the airport and Texas A&M. Hail core currently approaching the west and southwest sides of College Station at this time.

Circulation looks to be weakening some as it has broadened out, still very heavy rain, hail and strong winds along with additional tornadoes possible in the College Station area over the next hour. KCLL just reported 1.24'' of rain in the last 50min!

I hope what I see on radar (at 7:15pm) isn't the tornado reforming, but it looked like rain wrapping from NE to SW in a clockwork fashion around area where tornado was located.

Came back to Houston this weekend. But radar estimates/ reports from people at College Station were reporting pea- quarter size hail and rain totals around 3-4 inches! Pretty impressive to say the least.

Morning e-mail from Jeff:

Busy night across the area with slow moving thunderstorms producing another bout of excessive rainfall.

Since 400pm yesterday rainfall of 6-11 inches has fallen over Brazos and Burleson counties resulting in significant flash flooding. College Station recorded 4.11 inches of rainfall prior to midnight breaking a daily rainfall record for 2-3-2012. Widespread flooding has inundated much of Burleson County with nearly all roads across the county closed and impassable. In College Station and Bryan several roads are closed with creeks running well over their banks.

Cold front has caught up with the slow moving line of thunderstorms helping to increase the SE motion this morning. While hourly rainfall rates remain in the 1-2 inch range under the strongest cells, the training of this line is lessening. Scattered flooding problems will likely continue along this line especially as it moves into the more populated urban areas over the next hour leading to some street flooding.

Hydro:
Rainfall across the middle Brazos basin overnight will produce a major rise on the river from Bryan downstream this weekend. Since midnight the river at Bryan has risen 10 feet (5 ft in 2 hours) and is rising very quickly as extensive rainfall run-off is reaching the main channel. A flood wave will likely be generated on the main channel near Bryan and then begin to translate downstream to Hempstead , Richmond, and Rosharon this week.

Rainfall from yesterday has produced rises on the E Fork of the San Jacinto River, and the lower Trinity River, as well as Peach and Caney Creeks in Montgomery County and Luce Bayou in Liberty County.

Additional rainfall this morning and again on Sunday will delay flood recessions on these watersheds and may result in higher rises. Flood Warnings may be required today for some of the areas downstream of the excessive rainfall regions.

Don't mean to sound like a broken record (records were these black discs that played music lol) but how are we looking for tomorrow evening? Did the "front" arrive any earlier or does it look to stall out and linger with moisture?

I'm hoping it fast forwards and gets the heck out of dodge/ montgomery.

Unfortunately as long as SW flow aloft remains over the region, there is little change in the thinking regarding tomorrow on into next week. We are stuck in a damp pattern that doesn't appear to be changing anytime too soon. At least we'll have 'cooler temps'. I feel your pain, niner21. We need to pour a foundation and everyday it rains, the further behind schedule we get... ;)
