February 2019 picking up where February 2018 left off: Dreary

February is not Houston’s prettiest month, at least not recently. In February of 2018, 82% of all observations at Bush Airport reported some degree of overcast skies. “Overcast skies” in this case would be defined as any observation reporting “OVC” for the cloud deck. That could be anything from a high, thin overcast with some sun peaking through to low, gray clouds or fog. Either way, some sort of grayness to the sky.

This February is picking up where February 2018 left off, with lots of clouds around. (Data via Iowa State University IEM)

So far in February of 2019, we’re averaging 85% of observations featuring overcast conditions. Typically in February, Houston averages about 45% of observations with overcast skies. Basically, with the exception of the time right around sunset, it’s been gloomy so far this month for the second year in a row. And this weekend will not help that cause.

Today

Winter is back in force today. How far has the temperature fallen since this same time yesterday morning?

Temperatures are about 35° colder on average than they were this time yesterday across the Houston area. (NWS)

In Houston, we are running about 35 degrees colder than at this same time yesterday morning, starting today in the upper-30s or low-40s. Changes are a little greater north and a little less so south. Temperatures won’t move much today. Expect highs in the low-40s at best with a bit of a gusty north wind continuing.

Cloud cover will dominate today, with perhaps a few sunny breaks if we are lucky. In addition, we could see some sprinkles or light rain, especially along the immediate coast, as well as north of the Houston area, up toward Conroe or Huntsville. Up north, any of that light rain could mix with or even fall as ice pellets (sleet). It would be conversational, not impactful, but a good reminder of where we sit on the calendar.

Record-setting heat ends today in Houston, but gray skies will remain

The region’s anomalous warmth continued on Wednesday, as the city set a record high temperature of 82 degrees for February 6, breaking the mark of 81 degrees set in 2017. This also marked the first time Houston recorded a daytime temperature of 80 degrees or warmer this year. Lows this morning have only dropped down to around 70 degrees—more typical of late May or early June than this time of year—but this mid-winter warm spell will finally end today as a cold front sweeps through the area.

Lows on Thursday morning are about 25 degrees warmer than normal in Houston. (Weather Bell)

Thursday

Patchy fog has developed near the coast this morning, but for the most part coverage is thin inland due to some moderate surface winds mixing things up. The front should reach areas northwest of the region this morning, push through the city itself around noon-ish, and move off the coast this afternoon. In terms of rainfall, we’re still looking 1 to 3 tenths of an inch of rain, with the potential for some thunderstorms near the frontal passage. It’s probably not a bad idea to send your kids to school with a sweater for this afternoon, but temperatures aren’t really going to start falling until around sunset. Winds will gust this evening at or above 20mph, and lows Thursday night will drop into the low 40s, generally.

Record warmth for one more day in Houston before a front

Houston appears to have set a record for a “high minimum” temperature on Tuesday, February 5th, when the low temperature at Bush Intercontinental Airport only fell to 68 degrees—breaking the mark of 67 degrees set in 1927. This morning temperatures are warmer still at the airport, with lows only bottoming out at 71 degrees as of 6:15am. Another record minimum therefore seems likely, and Wednesday’s high temperature may well threaten the daily high for February 6 (81 degrees, set in 2017). A front on Thursday will abruptly end the anomalous warmth.

Wednesday

We can expect another warm and mostly gray day, much like we’ve already experienced this week in Houston. Highs should reach the upper 70s across the region, although we can’t rule out Houston’s first 80-degree mark if there are enough breaks in the clouds this afternoon. Slight rain chances will linger, but they should be only 10 to 20 percent for most of the area, with very light accumulations. Mostly just gray and warm today therefore, with south winds on the order of 10 to 15mph.

Soupy, warm weather remains in Houston until Thursday’s front

Dense fog is again the story this morning, as very warm air temperatures in the mid-60s overrun run nearshore sea surface temperatures 10 to 15 degrees cooler. It will take some time for the fog to burn off, perhaps not until late morning for some areas. We can expect foggy mornings (and nights) through Thursday morning before a cold front snaps the region back into more seasonal temperatures.

Tuesday and Wednesday

The next two days should more or less be carbon copies of Monday, with high temperatures in the mid- to upper-70s and lows only falling into the 60s. Some very light, very scattered showers are possible both days, but for the most part we should just see clouds. Perhaps the only notable change will be an increase in southerly winds on Wednesday, as lower pressures over the central United States bring winds up to 15 or 20mph.

We don’t expect too much rain with this week’s cold front. (Pivotal Weather)

Thursday

A cold front remains on track to push through Houston on Thursday, likely during the middle of the day. Rain chances will increase Wednesday night and Thursday morning ahead of the front, but again, accumulations don’t look too serious, with most parts of the area perhaps picking up two or three tenths of an inch. A few brief-lived thunderstorms will be possible. By Thursday afternoon or evening, rains should end as much colder and drier air blows in, bringing nighttime lows into the low 40s for most of Houston.
