Radar lighting up like a Christmas tree out towards San Marcos.
It’s going to be a close call for those of us in the southern part of the viewing area this evening. This round could go north of us. If it starts popping south of San Antonio and towards Victoria then I would feel a lot more confident about it. Latest HRR gives me about 6-7” tonight so we’ll see.

I emptied 2.05" from the rain gauge (last emptied Sunday).
Digital gauge had totaled 1.82"
Always good to have a backup. The wind/trees/rooftops mess with the totals....and it was windy when it was storming.

Do yall think the WPC might issue a high risk for flash fooding? This has the potential with another 2-4 days of heavy rain to be devastating for some areas.

It’s definitely a possibility.

***Dangerous flash flood event likely tonight-Wednesday night over SE TX.***
Short range models have become increasingly consistent today in suggesting the development of a corridor of slow moving excessive rainfall this evening into early Wednesday from roughly Conroe to Hempstead to Columbus that slowly moves east and south with time. Given the potential for an east-west or NE to SW line of training thunderstorms with strong low level inflow off the Gulf of Mexico is historically a dangerous flash flood setup for this area.
Where exactly the line anchors or trains for any extended period of time is questionable, but given moisture profiles, significant short duration rainfall totals of 2-4 inches per hour will be possible leading to rapid onset flash flooding.
There has been little change in the overall forecasted rainfall amounts today and would not be surprised if someone in SE TX sees 10-15 inches over the next 36 hours.
Expected rainfall rates and totals will likely push some creeks and bayous toward their banks and in some cases overbanks resulting in more significant widespread flooding. While this threat appears greatest north of I-10…the entire county and area is at risk.

For as long as I can remember, Tornado Watches are red and Severe Thunderstorm Watches are yellow.
You wake-up in 2021 and somebody thought it was a good idea to change it.

It changed at some point. It was traditionally designated like this on the major media outlets:

National Weather Service contrasted against Media. NWS has been yellow for Tornado Watches and a purpleish for Severe Thunderstorm Watches; that’s the standard in my opinion.

I have no clue what y’all are talking about. Tornado watches have always been red and severe thunderstorm watches have always been yellow. That’s elementary.

By some companies, groups - yes. But, that is not the current scheme used by the NWS. But, this will probably be changing over the next decade.

Only 1.70" the last 3 day in League City but that will change. Storms looking impressive over Central and S Central TX.

Tornado watch is verifying for sure. Could be a one-two punch with a serious flood and added severe threat.
