Some rain chances, but Tropical Storm Danielle remains well south

Good morning. Houston remains at the southern edge of a high pressure system, which should build over the metro region during the next couple of days. We’ll see some rain chances before that happens.

TODAY

I suspect rain chances later this afternoon will be similar to those on Sunday. While much of the area saw little or no rain, pockets of the city saw 0.5 to 1.0 inch of rain Sunday during primarily afternoon thunderstorms. Highs will likely climb into the low 90s.

This high pressure over the southeastern United States has kept a tropical system away from the Texas coast, and that’s probably a good thing. Tropical Storm Danielle formed in the southern Bay of Campeche this morning, but proximity to land is likely to prevent it from strengthening too much. Had it been allowed to move north toward the Texas coast, it would have had more time for development over open water. In any case, the system is going to be a rainmaker for Mexico, and is also notable as the earliest fourth tropical storm on record, beating Debby 2012 (June 23) and Dennis 2005 (July 5). It’s still not clear to me that this augurs a particularly bad overall hurricane season, because all the systems we’ve seen form have been fairly weak tropical storms.

Storms possible again on Father’s Day

After storms passed on Saturday evening Houston enjoyed some really pleasant weather—temperatures in the mid-70s with lower humidity. For those of us on the south side of Houston some tremendous rainbows were also visible. I saw a faint double rainbow from my home, but via Twitter Erin Eldridge shared the following photo which offers a much better view of the whole rainbow.

Some storms may spread across Houston this evening

Two clusters of thunderstorms developed this afternoon south of Houston—one near Sugar Land and the other Friendswood. These storms have produced isolated areas of 1 to 2 inches of rain and some reports of hail.

A larger area of storms associated with a boundary is moving from the northeast toward the Houston metro area. Some of the forecast models have indicated these storms will weaken as they approach Houston, but if anything they seem to be strengthening a little. If they hold together these storms will bring a good chance of rain to much of the area, especially east of downtown, beginning at around 7pm. Strong winds are also a threat.

Will these storms hold together as they reach Houston? Probably at least for the eastern side of the metro area. (Intellicast)

Hot still, but this weekend will bring some relief to Houston

After a couple of brutally hot days—96 and 97 degrees, respectively—we can expect more of the same today. The heat will break a bit later this weekend, however.

FRIDAY

High pressure will dominate again today, pushing highs into the upper 90s with mostly sunny skies. A heat advisory remains in effect due to the very warm weather.

SATURDAY

On Saturday temperatures will again be warm in the mid- to upper-90s, and the heat advisory remains in effect. However as high pressure retreats to the west, some slight rain chances are possible to the east of Interstate 45.

SATURDAY NIGHT through MONDAY

With high pressure weaker, and Houston open to the Gulf of Mexico, we’ll see some better rain chances beginning Saturday night and running into Sunday and possibly Monday. I don’t think we’re going to see any kind of significant flooding, but much of the area may well see one-half to as much as one inch of rain in total, and that will not be unwelcome to the area’s lawns and trees. Some brief, gusty winds are also possible.
