We had a mini tornado outbreak just a year ago on January 8th.Interesting that it effected some of the same areas.
From HGX
A warm front moved up through the region Saturday January 8th ushering in a moist, unstable airmass bringing tornadoes and flooding to portions of Southeast Texas. The first two tornadoes occurred in the late afternoon on 1/8 with the first one briefly touching down on the southside of Houston Bush Intercontinental Airport (IAH) at around 3:55pm with a second tornado occurring at around 4:20pm near the town of Dayton in Liberty County. There was a lull in the tornadic activity through the rest of the evening, but then another brief tornado occurred in the town of Montgomery in Montgomery County at around 9:40pm. Before the clock struck midnight, the last tornado of the day (but not of the event) occurred in Spring Valley, Harris County at 11:55pm CST. A tornadic supercell then dropped two tornadoes a couple hours later on 1/9 twice in the town of Humble at around 1:17am CST then again in the town of Kingwood at 1:25am. This tornado in Kingwood would then be the last tornado of the event.

Scattered showers and thunderstorms produced locally heavy rainfall through the event. Some of the highest amount fell in Harris, Montgomery, Polk, and Liberty counties where Flash Flood Warning were needed. The highest rainfall total of the event was 9.92" three miles southeast of Roman Forest in Montgomery County.
The flooding brought road closures to roads in Liberty County at CR2500 and at Plum Grove Rd near the town of Cleveland.

Okay, 2 events. The one I was thinking of was the 2020 mid January storm that wiped out my barn and killed one of our horses.

I got at least 5-8 inches of snow (most kept melting), I may have gotten over an inch of QPF.

We may need to start paying attention down the road in the 6-8 day range as a winter battle zone may set up right over our area, clash of the arctic airmass vs warm SE winds, this type of pattern is notorious for producing ice storms, the CMC and some of the other models hint at this, just gotta watch the trends, i will say the 12z GEFS ensemble is really active over the state during the next ~10 days, just my two cents as i figured its worth mentioning

On January 9, 2012, we had a high precipitation supercell churn along the I-59 corridor towards the NE producing a few tornado reports and widespread street flooding through Fort Bend and Harris County including the Houston Metro Area.

Tornado archives provides some perspective:

https://tornadoarchive.com/explorer/2.1 ... E)F4,(E)F5

5-7-76 f1 tornado followed almost the exact same path, just a slight shift in angle

12-31-84 f2 ran parallel almost half the distance, but on the se side of beltway 8.

Has the Deer Park tornado been graded yet, or is that the same one?
