Our soggy Tuesday is just the beginning of more stormy weather. We're under a flash flood watch through early Thursday morning and so far, with the rain coming in waves, the impact has been minimal. Rainfall totals today: Pearland 1.32", Bush .29", Hobby .75", Galveston .15", but College Station recorded 1.06", a record for this date. Get ready for more rain and the brunt of a severe weather threat. Initially, computer models were taking a low pressure system that was in California and moving it across Texas. That system was supposed to clear out by Wednesday. However, the depiction below shows the low "wrapping up" and moving more slowly out of west Texas. This means a more prolonged period of rain and, because of the orientation of the low pressure, a better chance for severe weather in the form of isolated tornadoes.
The swatch of orange/yellow in the depiction below near Houston is a sign to me that storms will line up and "train", or repeatedly move across the same areas. Even though today's rain has been light, don't let your guard down because we're on the verge of the worst of this storm episode.
