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.

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 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.

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.

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.

Today

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.

Wednesday

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.

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.

Houston’s mild Memorial Day weekend may soon turn stormy

After a quiet start to Memorial Day weekend we have some concerns about the second half of the holiday for the greater Houston area as our weather turns stormy. The problems should develop later this afternoon and evening as a weak front approaches the region from the northeast at about the same time as temperatures reach their warmest levels around 90 degrees.

Sunday afternoon and evening

For today, the principal area of concern is north of Interstate 10, where increasingly unstable air should allow for the development of thunderstorms, some of which could become severe. We’re going to have to watch for the possibility of damaging winds and hail, as well as some brief, localized flooding. I would not be surprised to see some areas pick up a quick two or three inches of rain in a short period of time.

Memorial Day

The forecast for Memorial Day is fairly complicated, because in addition to the diffuse frontal system, an area of disturbed weather is likely to move up the Texas coast, from Mexico. This could drive some rain showers and thunderstorms along the coast during the morning and midday hours, adding to the mess.

Overall, the likelihood of intermittent storms is fairly high for the Houston area through the holiday weekend, from Sunday afternoon, onward. While I’m not too concerned about flooding issues, I do expect most of the region to get 1 to 2 inches of rain, with higher isolated totals. For most of next week, the weather appears likely to remain unsettled, which isn’t a terrible way to start June as it will keep highs in the 80s, rather than the low 90s. But we will have to watch for potential flooding later in the week, depending on just how much rain comes between now and then.
