The National Weather Service has issued a flood advisory for much of the western half of the Houston area this afternoon. The warning comes as a large area of thunderstorms moves into the region from central Texas, and is in effect until 4:30pm CT. I’m especially concerned about the potential for lots of lightning.

The region’s moist atmosphere has already produced heavy rains and some flooding overnight near College Station, and this morning along the coast with some areas getting as much as 6 inches.

Would expect minor flooding from the system moving through on Sunday afternoon—rather than major flooding—but if you’re planning to be out and about this afternoon and evening in the Houston area, please take an umbrella and check the radar. Some parts of Houston may see 2 to 4 inches from these storms today and this evening.

Rain chances will remain on Monday and Tuesday before a cool front (yes, really) dries us out for the second half of the work week.

We have reached June 1, which marks the official beginning of hurricane season. You’ve probably seen lots of coverage about how this seems likely to be an “active” season for the Atlantic—however if you actually read NOAA’s forecast it calls for a 55 percent chance of near normal or below normal activity, with a 45 percent chance of above normal. Essentially, that’s 50-50, and not really worth worrying about any more than any other year. Truthfully, if you live near the Gulf coast you should have a plan for when a hurricane threatens (evacuate? where? pets? documents? supplies?), and then put it into place when a storm develops. You can rest assured that we’ll provide comprehensive coverage of any tropical weather that potentially threatens Texas. To that end, we’ll be unveiling a site sponsor for the entirety of the season soon.

Now, onto the forecast.

Thursday

Scattered showers and thunderstorms moved through Houston during the overnight hours dropping from less than a tenth of an inch to more than one inch of rain over western parts of Harris County. These showers have scoured some of the moisture from the air, and we’re likely to see a reprieve from rain through the morning hours. Whether we see some additional rain showers this afternoon will depend upon the extent to which our skies clear out after noon—sunnier skies will lead to warmer temperatures, and this would increase the likelihood of showers later in the afternoon and early evening. Look for highs in the mid-80s.

On the last day of May conditions are warm this morning, with almost summer-like readings in the 70s. A few rainy days could keep the low-90s heat away from us for the next week or so, however.

Today

It will be another warm day, with highs likely reaching into the upper 80s this afternoon. This daytime heat should combine with moisture to produce a decent chance of showers and thunderstorms this afternoon. I’m not anticipating widespread coverage, but for areas that do see rain, that rain could briefly be quite heavy.

Thursday

This should be a wetter day for the region, as moisture surges into the area from the south. We should expect widespread showers and thunderstorms, again, with some localized deluges possible. Mostly cloudy skies should help keep highs in the mid-80s, and most areas probably will see on the order of 1 inch of rain, or slightly less.
