Flood advisory issued for western half of Houston area

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.

Hurricane season starts, but no concerns for Houston yet

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.


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 again, off again rainy days likely until early next week in Houston

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.


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.


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.

A gray, somewhat wet week for Houston heading into June

Good morning. After some storms on Sunday night, Houston’s weather remained mostly calm on Memorial Day. As we enter June the region should remain in this gray pattern, with on-and-off rain chances for most of the rest of this week. This isn’t great weather for those who are looking for sunshine, but if you’re hoping to put off the start of Houston’s summertime slog of 90-degree days, you’re in luck.


Despite the mostly cloudy start this morning, Houston might actually see some sunshine later today—if only briefly. Moisture levels aren’t that high, so I’m only expecting a few scattered showers to go along with highs in the mid- to upper-80s. Overnight lows will be in the low to mid-70s for most of this week.


As moisture levels pick back up on Wednesday, we’ll see somewhat better rain chances, and we can’t rule out of a few scattered, heavy rain storms during the day. Highs should be in the mid-80s with mostly cloudy skies.

Thursday and Friday

By Thursday an upper-level disturbance should combine with fairly high moisture levels to produce a really healthy chance of rain across the Houston area. While we can’t rule out flooding given the time of year and moist atmosphere, it looks like these storms should produce 1 to 2 inches of rain to end the work week for most people, rather than an absolute deluge. We’ll be watching it closely regardless. Highs should remain in the mid-80s.

Rain accumulation forecast for now through Sunday. (Weather Bell)

Next weekend

The forecast for this weekend isn’t particularly clear, but the best bet is that we’re going to remain in this quasi-moist regime, with decent rain chances and partly to mostly cloudy skies. At this point I don’t think we’re looking at any significant flooding, but that remains a potential threat that we’ll have to look out for. This pattern may hold through the early part of next week before we finally see clearing conditions and characteristically warmer summer days in the low 90s. Honestly, there are worse ways to begin the month of June—such as with a tropical storm or highs in the 100s.
