Some active weather is likely to continue over the next 24 hours, so we’ll get right into that before talking about a mostly nice weekend to follow.
Early morning Friday
Radar as of 5:40 this morning, shows minimal amounts of showers around Houston. There’s some rain well to the north of Conroe that is falling apart.
Scattered showers and storms were pressing east of Austin, more toward the Brazos Valley. Heavier rain and storms (non-severe) in San Antonio were sliding east toward Victoria and places west of Houston. Over the next few hours, these showers will gradually migrate toward Houston, but for the most part, our early morning looks fairly quiet.
Friday late morning & afternoon
Weather modeling has been some kind of inconsistent over the last couple days in terms of what and where with rainfall. So to some degree, this leaves us flying partially blind today. We can tell you a couple things with confidence: First, there will be plenty of moisture available for storms today. This is probably the most we’ve seen all week, so it should mean coverage of storms today will be at their highest of the week for Houston. Second, we need a trigger, and with numerous boundaries in the area and more coming from the San Antonio area, that should be enough to get showers and storms going later this morning and this afternoon.
What we cannot tell you with much specificity, and what is naturally most frustrating to us (and you I’m sure) is exactly where and when the heaviest rains will occur. The image above is a sample from two short-range, high resolution models we look at each day. They are valid for the same time: 1 PM this afternoon. The HRRR (at left) shows an organized heavy cluster of storms. The NAM (right) shows scattered showers. I am leaning toward the HRRR idea right now, but basically at this point, the best advice we can give you is to bring an umbrella and be ready to potentially deal with some storms and heavy rain from late morning into this evening.
In terms of severe weather, it is possible we see some strong winds or hail, but the biggest concern with these storms will be heavy rain and localized street flooding. Any storms could produce rain rates of 1-2″ per hour or more which, if over one place, could lead to some street flooding.
