For the first time in more than a week, Houston’s radar is filling up with light to moderate rain showers this morning. The region will see a reasonable chance of rain today and Tuesday before decreasing chances by mid-week. After that the heat will return in force, with highs in the upper 90s to 100 degrees by the coming weekend. Houston has yet to hit the century mark in temperatures in 2020, but that could change by Saturday or Sunday.

Monday

A combination of an upper-level disturbance and moist atmosphere will allow clouds to form today, and support scattered shower development, with the better chances likely along and north of Interstate 10. We don’t anticipate anything too heavy falling today, but the additional clouds should help to modulate temperatures after highs in the mid- to upper-90s over the last week. Expect highs today in the low-90s. Humidity will still be quite high, and don’t expect overnight low temperatures to fall much below 80 degrees.

Tuesday

This day will probably offer our best chance of rain for this week—and perhaps beyond. I think most areas probably will see at least light rain, with an average of about one-quarter inch of rainfall for most. A few isolated areas may see 1 inch or more of rain. Mostly cloudy skies should help hold high temperatures to about 90 degrees, but it will definitely be a steamy 90 degrees.

Here comes the heat. With high pressure in the vicinity of Houston, we’re heading into a classic heat pattern for the region during summer. It can get hotter than this—I don’t think the region will see much 100-degree weather this time—but the combination of heat and humidity will be stultifying during the midday hours.

Thursday and Friday

These two days will be similar, so there’s no reason to separate them out. Both will see lots of sunshine by the late morning hours and throughout the day. Expect high temperatures to reach the mid- to upper-90s, with lows falling into the upper 70s for most areas except the coast. Light winds, out of the south at about 5 mph, will not provide much relief.

Independence Day

Conditions won’t change much on July Fourth. We may see a few clouds, and there will be some slight rain chances to the east of Interstate 45. But for most of us, conditions will remain hot and sunny, with highs likely in the upper 90s.

Sunday through Tuesday

It looks like an upper-level low pressure system will now set up to the east of Houston, over the Gulf of Mexico, and so the best rain chances likely will set up for the eastern half of the metro area early next week. Confidence remains low—but if you live in a place like Katy I would not expect much rain, whereas if you’re in Baytown 0.5 to 1 inch may be in the cards. In any case, a few more clouds should take a bit of the edge off of temperatures for a few days.

After this, high pressure should again build over the region, and the second half of next week looks quite hot. Summer, y’all!

June ended up with an average temperature of 82.5 degrees—which is bang on the normal temperature for Bush Intercontinental Airport over the last three decades. Thanks to persistent cloud cover and days of rain, the second half of the month was generally cooler after a hot start to the month. That may make the onset of July, and more typical summertime heat, a little more difficult to bear. For although this week’s heat won’t be exceptional, it will be a bit warmer than normal for July, which is to say hot and humid.

Wednesday

It is awfully sticky outside this morning, with temperatures generally at or above 80 degrees with dewpoints not far behind. There is a bit of dust in the air, as evidenced by the photos above. Some lingering clouds and a bit of moisture may help generate a few isolated showers this morning, but for the most part we should see clearing skies and soaring temperatures today, with highs rising into the mid-90s. Winds will be prominent out of the south, gusting up to 20 mph. Low temperatures Wednesday night will again struggle to drop below 80 degrees for much of the metro area.

Thursday and Friday

Welcome to summer. With high pressure in control of the region’s weather we can expect a pair of hot and sunny days. Look for temperatures to rise into the upper 90s for most of the region, with plenty of humidity pushing the heat index above 100 degrees. These are the kinds of days when you’ll step outside in the afternoon and say, “Oh yeah, now I remember what summer in Houston can feel like.”

Good morning. There are few surprises in today’s forecast, as Houston is likely to remain hot and humid through the rest of the week. The trend will be toward hotter and sunnier weather throughout the work week, with early July feeling a lot like July should feel. A few showers may crop up on Independence Day, but the better rain chances likely will wait until Sunday or Monday.

Tuesday

A few, light showers have popped up to the north of Houston this morning, but we expect these to be transient. Thanks to a southerly wind gusting up to 25mph, moisture continues to pump into the region, and this should keep our skies partly to mostly cloudy today. In turn, these clouds will limit high temperatures today to the low 90s. These clouds will also make for another very warm night, with overnight lows unlikely to fall below 80 degrees for most of the area.

Wednesday

A similar day to Tuesday in terms of humidity and southerly winds. However, as high pressure continues to build over the region this should limit the ability of air to rise, and accordingly cut down on cloud cover. Highs will rise into the low- to mid-90s with non-existent rain chances. Additionally, we should see another plume of Saharan dust move into the region, although it will not be as thick as what we saw last Friday and Saturday.
