A lot to get to today, but the big headline this morning is that Saturday’s forecast has changed. You’ll want the jacket handy.
As of now, we think that, while we will have scattered showers around today, the majority of the daytime should be under control in Houston and points south and west, as capping (which helps inhibit thunderstorm development) will likely be in place much of the day. So at this point, we aren’t expecting anything too serious during the daytime. However, as you go north and east of Houston, a few more organized, stronger storms may get going this afternoon.
Severe weather risk is pretty minimal in Houston, but with weaker capping northeast of Houston, chances of some healthier thunderstorms goes up as you move in that direction. (Storm Prediction Center)
For that reason, the Storm Prediction Center has placed counties north and northeast of Houston in “Slight” (or level 2) risk for severe weather. The most volatile ingredients for severe weather today will again be in far northeast Texas or northern Louisiana. But we can’t rule out a few strong to severe storms northeast of a line from about The Woodlands through Port Arthur. We’ll keep tabs on this today in case anything changes.
The cold front, well to our north today, will advance south into our area overnight tonight, probably well after midnight. One difference with this front versus the last couple we’ve had come through overnight: Whereas the last couple fronts timed in the 10 PM to 2 AM window, this one will likely be later, say, 2 to 6 AM-ish. So, you may be woken up later in slumber by a rumble of thunder.
Between today’s showers and storms and tonight’s front, rain amounts may be a bit variable across the region.
Total rainfall today through Saturday shouldn’t be too impressive, though a few spots could see a little more than shown here, mainly northeast of Houston. (NWS WPC/Weather Bell)
On average, I think rain amounts will be a few tenths to half an inch in most places. Some of us may get a little more (perhaps 1-2″ or so with some thunderstorms today). Some places south and west of Houston may only see a small amount of rain. We don’t have any serious flooding concerns from this system.
