As air temperatures have fallen down near to dewpoint temperatures this morning, we’ve seen the development of radiation fog across much of the Houston area. This should eventually burn off by mid-morning or so, as air temperatures begin to rise.

Tuesday, Tuesday night, and Wednesday

After the fog burns off, skies should become partly to mostly cloudy today, with highs in the mid-60s. Rains should hold off until at least sunset, and as high pressure moves off to the east we should see the development of some scattered, light showers to the west or southwest of Houston this evening.

Lows tonight will only fall into the mid-50s, and we’re likely to see intermittent, scattered showers and thunderstorms during the overnight hours and through 10 or 11am on Wednesday. As for accumulations, for now the models aren’t showing anything too extreme. Accumulations of a few tenths of an inch seem most likely near the coast and in Houston, with one-half inch or perhaps a bit more for inland areas. Skies will remain mostly cloudy on Wednesday afternoon as a cold front nears the area, with highs probably pushing into the mid- to upper-60s.

Temperatures during the first half of December were slightly cooler than normal, but looking ahead to most of the rest of the month it appears as though our weather will take a turn to become slightly warmer than normal. I don’t think we’ll see any weather above the low- to mid-70s, but both days and nights should for the most part be fairly moderate for the beginning of winter.

Monday

Temperatures this morning are in the low 50s for the most part—colder well inland, of course—and we’ll see a healthy warm-up today as winds have shifted to come out of the south or southwest. I’d expect highs today to push up into the mid-60s or near 70 degrees under partly to mostly sunny skies. Lows tonight will be similar to Sunday night, and as temperatures fall down toward the dewpoint temperature we could see some fog develop late Monday night and Tuesday morning.

Tuesday and Wednesday

Highs on Tuesday will reach back into the upper 60s under partly to mostly cloudy skies, and moderately rising moisture levels will set the stage for rain showers Tuesday night. No models are really indicating the potential for heavy rain right now (and anticipated atmospheric moisture levels don’t really support that), so I think we’re probably looking at a few tenths of an inch of rain. Rain chances should slacken by Wednesday morning, and depending upon how much skies clear we could see highs of around 70 degrees with a sunny afternoon.

As expected, an area of showers moved through the metro area this morning prior to sunrise, dropping 0.5 to 1.5 inch of rain for most of the region. This mass of showers has now pushed east of the area, and as of 6 a.m. the trailing edge was about half way between Houston and Beaumont. A gusty front will follow this afternoon or evening.

Thursday

Some scattered showers will remain possible today until the early afternoon hours, but we’ll see nothing like the organized storms that pushed through earlier this morning. Skies may even become partly sunny this afternoon before westerly winds kick in and a strong front arrives.

This front may produce a very thin line of storms, or a few scattered thunderstorms, as it moves through, but for the most part I think it will probably be dry in terms of rainfall. This westerly flow will push temperatures down this evening, and we can expect a gusty overnight with lows generally in the mid-40s. If you’re heading out this evening, please bring at least a windbreaker.

Friday

This will be a cold, gray, and windy day—with gusts up to about 30mph or perhaps a bit higher along the coast. Highs for most parts of the region will barely reach 50 degrees. Despite mostly cloudy skies Friday night, lows still should drop down to around 40 in most of the city.

Conditions are quite a bit warmer across the metro area this morning, with most of the region somewhere in the 50s. Our forecast remains much the same as it’s been—with unsettled weather for a day or so, breezy weather, and then clearing conditions for what should be an excellent December weekend.

Wednesday

Today will be warm-ish for mid-December, with highs in the upper 60s under cloudy skies. Steady, southerly winds will bring the humidity, and also be pushing up moisture levels that will boost rain chances during the overnight hours. Although some light showers are possible Wednesday afternoon and evening, most high-resolution models hold off any stronger storms until later Wednesday night and Thursday morning.

Thursday morning

As an upper-level disturbance moves in from the west, and a cold front barrels down from the northwest, it now appears as though a fairly robust line of showers will move through southeast Texas on Thursday morning, roughly from around 2am through 8am.

This line of storms doesn’t look too severe—although some thunderstorms are possible—but showers should be heavy enough to drop 1 to 2 inches of rainfall on their way through the area. Fortunately the storms should make fairly steady progress and not linger too long.
