“Winter” ends on a warm note (of course!) before a mid-week front

After a brief cool spell this weekend, perhaps it is only right that Houston ends meteorological winter (December through February) on a warm note. Houston has already set a record for most 80-degree days this winter, and it seems likely we will end with the warmest average temperature in more than 120 years of records. We’ll have the full wrap-up on that later this week when the numbers become official.

But it hasn’t just been Houston of course. I wanted to share with you this amazing tidbit from the National Weather Service office in the Windy City: “Chicago’s about to do something its never done in 146 years of record keeping: go the entire months of January & February with no snow on the ground.”

Today and Tuesday

Houston will rise back into the 80s today and Tuesday to end winter, after overnight lows barely dropped into the upper 60s on Monday morning.

Although moisture levels will be fairly high for the next two days, there’s some question as to whether it will actually rain. This is due to a capping inversion, which probably will hold for most of the area. An inversion occurs where temperatures above the surface of the Earth are higher than at the surface, and this prevents warm, moist air at the surface from rising. In any case, know that there is the potential for showers and thunderstorms to develop the next couple of days, but they probably won’t due to the cap.

A mostly nice weekend for Houston

After a nice, albeit warm day on Thursday, we’ll see a near-repeat today. This before a cold front gives us even nicer weather tomorrow.

Today & Saturday

No record highs were set on Thursday, though Houston did eclipse 80° for the 19th time this winter, extending our record. We should be able to make it an even 20 days today. Officially, highs should peak in the low to mid 80s after some morning clouds give way to sunshine.

Speaking of clouds, be on the lookout this morning (especially southeast of Houston), as there could be some neat wavy or rolling type low clouds. What appears to be an “undular bore” or “gravity wave” is coming through Houston this morning.

It’s not a rare event, but it’s cool when you can catch it.

You may not really notice it, but a cold front is going to plow through the region later today. The wind will shift to an offshore direction and humidity will plummet.

This will lead to a crisp, cool night tonight with lows in 40s in most places (near 50 in the city). It also means Saturday will be epic. Highs will hit the upper 60s to near 70°, and we’ll have oodles of sunshine and low humidity. Bottle it up and save it.

Houston weather on cruise control

Houston’s weather is on cruise control right now, and this delightful stretch of weather is still on track to continue into the weekend. The forecast in a moment, but first some housekeeping.

Records Fall

Yesterday saw Houston hit 83°, making it our 18th day with temperatures at or above 80° this “winter,” officially a new record. The old record was 17 days set in the winters of 1995-96, 1956-57, and 1910-11. We should be able to notch at least two, possibly three more 80 degree days before February and our definition of winter ends.

Another, more intriguing item I’ve been tracking has been Galveston and their affinity for record high temperatures this winter. In fact, Galveston has tied or set new record highs on 31 days since November 1st of this past year. It’s not as if Galveston is new to recording weather data either. Records there go all the way back to 1874, which is a really solid set of data for a location. Houston has only set 12 new record highs in that same span of time, though that is also pretty impressive.

Now, I’m not sure what the odds are of breaking 31 new records in less than four months, but they have to be slim. The primary factor? Likely the Gulf of Mexico. The Gulf is considered to be at a record warm level this winter.

But, out of an abundance of caution, I reached out to the National Weather Service office in League City to see if they had any concerns about thermometer calibration or recent land-use changes at Scholes Field in Galveston, where the temperature is recorded. They don’t believe there are any siting or thermometer issues, as the days that Galveston has broken records have occurred when, meteorologically, it made sense (temperatures start the day just warm enough to allow Galveston to capitalize on warmer than usual air masses in the afternoon). It’s just been that sort of “winter,” and it’s led to an incredible piling up of record high temperatures along the Texas Gulf coast.

Houston’s seasonally warm (but pretty darn nice) weather continues

Today will get off to a cool start, but conditions are going to warm up fairly quickly across Houston, and we’ll be warm—but not unpleasantly so—for the rest of the work week.

Wednesday and Thursday

As high pressure builds over the area, expect mostly sunny skies and highs of around 80 degrees, with some inland areas perhaps climbing into the low- to mid-80s. Still, we can expect conditions to cool down reasonably quickly during the evening hours, with overnight low temperatures in the 50s for inland areas, and 60s along the coast.

Friday

Another warm day, with mostly sunny skies and highs of around 80 degrees. The difference will be that a cold front arrives on Friday afternoon or evening. At this time the front still looks dry, so I’m not expecting any rain along with its passage.
