Good morning—and for most of you its quite the cold one. Temperatures have fallen to freezing, or below, for most of the region except for the coast and the central Houston urban core (click the map below for details). Outlying areas such as Conroe, Cleveland, and Dayton have recorded temperatures in the upper 20s this morning. This should be the last of the really cold nights for awhile.

Thursday

Winds are generally calm this morning, and as high pressure moves off, this will open the region to a more easterly flow. This somewhat more moist flow should allow for the development of some clouds later today, and especially tonight. Highs today should reach about 60 degrees, give or take, with light easterly winds. As clouds build overnight, lows should only fall into the mid-40s

Friday

The forecast for the first part of the weekend has changed somewhat. As atmospheric moisture levels rise, and an upper-level system in the atmosphere provides the impetus for rising air, we’re going to see some decent rain chances. However, most of the region will probably stay dry throughout the day Friday—the best rain chances appear to be west of Harris County. Expect cloudy skies, and a high of around 60 degrees. Scattered, light rain should gradually spread into the greater Houston region during the overnight hours, into Saturday morning.

Temperatures have fallen to freezing levels this morning at some locations, including The Woodlands and Sugar Land, while remaining just above freezing in downtown Houston and closer to the coast. In short, it’s a cold morning, but at least the winds have died down across the region. It will feel like winter for a few more days before a warming trend next week.

Wednesday

Today will be a pleasant winter-like day for the region, with highs generally in the upper 50s under mostly sunny skies. Winds will be calm, to just a few mph out of the north. Low temperatures Wednesday night will probably be a couple of degrees warmer than Tuesday night, but a light freeze remains possible for inland areas. Venus is brilliant in the evening sky—be sure and check it out after sunset.

Thursday

Another mostly sunny day, although as light winds shift to come from the east we may begin to see development of a few clouds during the afternoon. Highs will likely rise to around 60 degrees for most of the region. This changing flow, along with additional cloud development, should keep lows in the 40s on Thursday night.

Friday

This should be a gray and fairly gloomy day. There will be a couple of impulses for rain—the first during the day with rising moisture levels, and the second early on Saturday morning as an upper level system drags a front through the region. Accumulations look quite modest in Houston, as most of the region probably will see about one-half inch of rain, or less. Regions near Matagorda Bay could see as much as 1 inch. Highs Friday will reach about 60 degrees.

Welcome back to winter, Houston, where lows have generally dropped to around 40 degrees this morning. A freeze is possible later this week for parts of Houston, especially north of the city. Oh, and looking ahead to the weekend—it should be gorgeous again.

Tuesday

Skies are clear near the coast this morning, and should clear out over the entirety of the region throughout today. Even with the sunshine today, however, the cold air mass should help to limit temperatures to about 50 degrees. It will feel even colder, as a breeze persists out of the north at about 15mph, with occasional gusts.

Wednesday and Thursday

Clear skies and weakening winds will lead to ideal cooling conditions on Wednesday and Thursday mornings. Expect temperatures in the mid- to upper-30s along the coast and just inland on both mornings, lows in the mid-30s to near freezing downtown, and lows at or just below freezing for Bush Intercontinental Airport and points north. Both days should be mostly sunny, although we probably will start to see the return of some clouds by Thursday afternoon along with the onshore flow. With light winds, we’ll see temperatures in the mid-50s to around 60 degrees.

A blustery front will blow into Houston on Monday, setting the stage for cold December weather this week. For now, we still expect milder conditions for Christmas week in Houston, with daytime highs possibly in the 70s by Christmas Day itself. There are obviously still nine days to go in the forecast, so details remain fuzzy.

Monday

Today is starting out warm and muggy, with patchy fog. Low temperatures at some locations in Houston on Monday did not fall below 70 degrees. But if you’re wondering whether this is September or December, Mother Nature will soon answer this question for you. A strong cold front will push through the region today, by mid-morning for areas northwest of Houston, around noon for downtown, and offshore by 4pm. We’ll see some light-to-moderate precipitation with the front, but accumulations probably will be less than one-quarter inch for most. Temperatures will drop 10 to 15 degrees, from the mid-70s, as the front passes, and the mercury will be in the 50s by this evening.

Tuesday

Skies will clear out on Tuesday as drier air moves into Houston. We’ll feel the drier air as winds gust to 25mph or higher. With temperatures only climbing into the mid-50s, this will be a brisk day before likely the coldest night of the week on Tuesday night. Some parts of the region north and west of downtown are likely to see a light freeze early on Wednesday.

Wednesday

Sunny, with a high in the upper 50s. After a chilly start, this day will feel warmer than Tuesday because the brisk northerly winds will have subsided.
