Houston won’t reach record lows this morning (38 degrees, set in 1983), but for mid-April it is quite cold out, with upper 30s north of the city in places like Conroe and Cleveland, and mid- to upper-40s across most of the rest of the region except for coastal areas. I feel confident in writing that this will be our coldest spell of weather—Sunday and Monday mornings—for at least six months. We’ll return to more seasonal conditions for the rest of this week.

Monday

A fine, fine day with only very light winds, sunny skies, and high temperatures in the upper 70s. Later this afternoon winds will swing to come out of the south, representing the beginning of an onshore flow, but we’ll still see a cool-ish night tonight, with lows in the upper 50s for inland areas, and lower 60s along the coast.

Tuesday and Wednesday

These days will be a bit warmer, and more humid as atmospheric moisture levels rise. The southerly winds could be gusty at times. I’d expect high temperatures in the low 80s, with warmer nights in the mid- to upper 60s. I think we’re still going to see partly to mostly sunny skies. A weak cool front will push into Houston on Wednesday, and probably move just off the coast. While we can’t 100 percent rule out any showers with this front, I think a capping inversion will prevent most people from seeing any rainfall.

Overall, the forecast remains pretty much the same. We’re watching for the possibility of storms on Friday night with the passage of a pretty robust cold front, and then looking for several days of really pleasant spring-time weather.

Thursday

The story for today will be winds. Onshore breezes will ramp up to 10 to 20 mph this afternoon, with higher gusts, in response to a large low pressure system in the Midwestern United States. Along with these winds, Houston should see a partly to mostly sunny day, with high temperatures around 80 degrees. A warm night, with lows only falling to around 70 degrees, will follow.

Friday through Saturday morning

Scattered showers, and a few thunderstorms, will be possible during the daytime on Friday as a cold front moves into Texas, but a capping inversion probably will keep most activity north of the Houston metro area. Most likely, we will have to wait until around sunset, or perhaps the overnight hours, for rain chances to really rise as the front moves through Houston.

Forecast models indicate a relatively quickly moving line of storms is likely to form along the front, although it’s not clear how intense these storms will be as the slide down toward Houston and the coast. Most areas probably will see less than 1 inch of rain as the front rolls through, and if this line of storms is broken, parts of Houston may not see much rainfall at all. The front will push off the coast by around 7am on Saturday, ending the chances of any storms, although some light rain may linger for a few hours.

It’s chilly across Houston this morning, with lows ranging from about the lower 40s up north in Conroe to the mid-50s near the coast. After this morning, we’ll enter a warming trend with rising moisture levels that will set the stage for thunderstorms and potentially some severe weather later on Friday and Saturday morning.

Wednesday

Highs today will rise into the upper 70s, with sunny skies. This will be another gorgeous spring day for Houston; but with light, southerly winds resuming this morning, overnight temperatures will probably be a good 10 to 15 degrees warmer tonight than they were Tuesday night.

Thursday

Another mostly sunny day, but we’re definitely going to feel the onshore flow resume in earnest, with gusty southerly winds, and this will help to ramp up humidity levels. Highs will probably level off at about 80 degrees, and with clouds building Thursday evening we can expect a warm, almost summer-like night with overnight lows only falling into the lower 70s for most of Houston.

When the clock struck 2:10pm on Monday, Houston’s temperature rose from 59 to 61 degrees at Bush Intercontinental Airport. Thus ended a streak of 51 hours of temperatures below 60 degrees, which Matt notes is the region’s longest streak of sub-60 degree weather in April since Houston went 61 straight hours from April 6-9, 2007. But fear not, lovers of cool weather, as the temperature remained in the low 60s for only about 12 hours, before falling back into the 50s this morning as another weak cool front moved into the region.

Tuesday and Wednesday

Prepare yourself for a couple of days of exceptional weather. With modest northerly winds, and clearing skies, highs Tuesday should climb into the mid-70s, and on Wednesday into the upper-70s. Lows Tuesday night will generally be in the 50s, and several degrees warmer on Wednesday night as the onshore flow resumes. Enjoy!
