Rain showers likely today as a rainy pattern sets in through the weekend

In brief: Our overall pattern is definitely changing, with rainfall likely today and tonight, and then again this weekend. Although precipitation will be plentiful, sunshine will be scarce until at least Monday. Our temperatures will go up and down, with Friday looking especially chilly even during the daytime.

Wednesday

Warmer and more humid air is spreading inland from the Gulf of Mexico this morning as a southerly flow takes hold, and this will set the stage for healthy rainfall today and into tonight. It appears that the most organized set of storms will move in from the southwest later this morning, pushing into the central Houston area around noon before lifting off to the east-northeast.

What to expect? Mostly this should be light to moderate rainfall. However there is a slight, and I do mean slight chance of something stronger such as gusty winds and thunderstorms. It’s possible that areas north of Interstate 10 may even see a tornado warning, but that is much more unlikely than likely to happen. Anyway, most of the greater Houston region should see some rain, with general totals on the order of 0.25 to 1 inch. However there will likely be some part of town, maybe in the Sugar Land or Pearland areas, that probably hits a bullseye of 2 inches or more. Chances for lighter rain continue this evening and into the overnight hours.

Highs today will reach the lower 70s, with fairly sticky dewpoints. Temperatures tonight will drop into the 60s, with drier air starting to arrive after midnight.

Thursday

As a cool front pushes the warmer air back offshore, look for a cool and cloudy day Thursday, with daytime temperatures likely in the vicinity of 60 degrees. Rain chances should be low to non-existent during the daytime hours and overnight. Lows on Thursday night are chilly, dropping into the low- to mid-40s for much of Houston.

Friday

A colder day still, with highs likely topping out in the 50s, beneath gray skies. Lows will again drop into the 40s on Friday night with some light rain possible late.

Saturday and Sunday

If you have outdoor plans for this weekend, I would describe the forecast as challenging. Saturday looks to be another cool and gray day, with highs in 50s to lower 60s. The likelihood of rain, probably light, is about 50 percent during the daytime hours. By Saturday evening and overnight we will probably start to feel the influence of a coastal low pressure system, and this will increase rain chances on Saturday night through much of Sunday. Highs on Sunday will probably be in the low 70s, with muggy air. The bottom line is that any outdoor activities on Saturday evening through Sunday night will face the distinct possibility of rain. Most of the area should see 2 to 4 inches of rain through Monday morning.

Next week

Skies look to clear out some on Monday, giving us our warmest day of the forecast period as highs push well into the 70s. After that another front appears likely, driving lows down at least into the 40s by Tuesday or Wednesday. We’ll have to see.
