On Sunday, the high temperature at Bush Intercontinental Airport reached 91 degrees. This came to within one degree of the all-time record for Oct. 14, set in 2015. We can consider this the last hurrah of summer for 2018, as fall will more fully assert control this week, and seems unlikely to relinquish its grip completely in the weeks ahead. I can confidently predict that we will see no more 90-degree temperatures this year given the overall cooler outlook for the next two weeks. (The latest 90-degree day on record in Houston came on Oct. 29, 1991).
Today, our weather will make a dramatic shift from summer into serious fall-like conditions. By 7am a cold front had already pushed through northern areas such as Huntsville and Conroe, and should move off the coast by around noon today. What will follow can probably be best described as Seattle-like conditions, as temperatures fall from the mid-70s this morning across the region into the 60s this afternoon, and 50s tonight.
This will not be a classic blue-norther front, as the cold air mass is rather shallow, and this will allow plenty of clouds to form a few thousand feet up in the atmosphere, and this essentially means that we’ll have on-and-off rain showers later Monday, Monday night, and Tuesday.
Houston’s last high temperature of 60 degrees, or below, came back on April 8 when a strong cold front hit the region. A portion of the region may not reach 60 on Tuesday, as clouds blanket the region with intermittent rainfall.
We may see some brief, localized heavy showers but for the most part rain amounts will be completely manageable. Conditions will be dreary out. Fireplaces may be needed inside. Dare I say it will feel almost winter-like out there?
Another dreary day. Temperatures on Wednesday morning will drop into the low 50s for most of the region, and then only warm into the low 60s for Houston. Rain chances will be somewhat reduced, but clouds will still be omnipresent.
We’ll start to see a warming trend, as highs creep back up to around 70 degrees. We should still expect cloudy skies and scattered showers.
Moisture levels surge toward the end of the week, and it seems like we’ll see widespread showers on Friday, along with high temperatures in the mid-70s.
Saturday and Sunday
We’ve already had a lot of questions about this weekend, and I’m afraid there’s not great news for outdoor activities. While the forecast is still in flux, we have a couple of considerations. That surge of moisture may be ebbing by Saturday, but at the same time another cold front will be advancing through Texas. Add it all up, and I think we’ll see maybe a 50 percent chance of showers and thunderstorms on Saturday, with highs somewhere in the range of the mid-70s, with fairly high humidity.
Sunday will depend upon the timing of the aforementioned front, in terms of both rain chances and temperatures. We do, at this time, expect lower rain chances Sunday, and drier air if the front moves through. Skies still look cloudy, however, and we may not see the Sun for a prolonged period of time until next Tuesday or Wednesday. Seattle, indeed.
