Late winter roller coaster ride for Houston

One question I’ve noticed from several folks in recent days has been some variant on “is it safe to tend to the garden yet?”

While we’ll probably avoid any sort of serious cold over the next 7-10 days, the advice I’ve been giving people is to give it at least another week or two. There’s a lot of uncertainty in the weather forecast going into mid and late February, and I’m just not convinced we’re completely out of the woods here in the area. Frosts can cause issues; it doesn’t take 20 degree weather to be problematic. On average, Houston’s last sub-32 degree morning is around February 15th. We’ve done as late as April 10, 1973, and, more recently, as late as March 21, 1996. Yes, it can get cold well into March here. As much as we’d love to say yes, go ahead and get busy, it’s probably prudent to just sit tight a little longer if you can. This winter’s surprised us more than once. We’ll keep you posted.

On to the forecast.

Today through Wednesday

After a mild Sunday, we’ll start the week just a bit cooler behind yesterday’s cold front. Look for upper 50s under clouds or lower 60s with more frequent sunshine today. We’ll have more clouds than sun in general, and a few sprinkles or pockets of drizzle could develop this afternoon, especially south/east of US-59. Onshore flow will continue to ramp up tonight. That should mean more clouds, showers, sprinkles, and also some fog around heading into Tuesday morning.

On Tuesday, we’ll have a warm air mass in place, along with increasing Gulf moisture. This should set the stage for scattered showers and perhaps some thunderstorms across the area. I don’t think everyone will see thunderstorms, but there is a chance for some stronger, hail-producing ones, primarily north of I-10 later Tuesday into Tuesday evening.

Expect temperatures on Tuesday to warm from around 60° in the morning to around 70° later. Tuesday night should see the best chance of storms shift a little further north of our area. A cold front will finally approach the area on Wednesday, cutting northwest to southeast Wednesday morning. We’ll start Wednesday probably in the mid 60s, but by midday or so, temperatures will likely drop back into and through the 50s. Plan to dress for two seasons on Wednesday. With the front, expect another round of showers and a chance of thunderstorms in the morning, and a continued chance of showers or some storms through the afternoon.

Total forecast rainfall over the next couple days shouldn’t be too serious, though a few places will likely see just a little bit more than depicted here. (WPC/Weather Bell)

On average, expect a quarter to half inch of rainfall through Wednesday evening. Some areas may see a little more if showers and storms are persistent. As noted on the map above, some areas south of Houston could even see a bit less.

Cooler, cloudy, winter-lite type weather today

Today will be one of the Houston days I like to call “Winter-Lite.” It’s definitely chilly by Texas standards, but it’s really not going to be frigid. We’ll have some ups and downs in the days ahead. We’re also watching Texas slip deeper into drought. More on that at the bottom of the post.

Today & Weekend

Our cold front slipped through the area overnight. Rain chances should be minimal to near zero today. Basically, today looks mainly cloudy, breezy, and chilly with temperatures stuck in the lower or middle 50s.

If you have outdoor plans this weekend and can choose Sunday over Saturday, that’s the right play. Tonight will start quiet with just some clouds. The Gulf will see a trough and warm front develop and begin to push back toward us. As it does so, a couple of disturbances several thousand feet up will approach from the west. The combination of these features will likely lead to showers developing overnight.

Unfortunately, I think this means Saturday will be damp. Look for showers, periods of rain, or even a thunderstorm to persist through Saturday morning and into the afternoon. How much rain? I’m thinking around a quarter inch in most spots, maybe a little less south and west or more north and east.

Total rainfall through Saturday evening should be around a quarter inch, with higher amounts possible, mainly east of US-59. (WPC/Weather Bell)

Last weekend sort of snuck up on us, and while model guidance has trended slightly rainier this weekend, I don’t think we’ll see nearly as much rain as we did last Saturday. So we’ll call Saturday a damp one, but not as wet as last weekend.

Temperatures should warm through the 50s during the day, perhaps getting into the 60s by later in the afternoon tomorrow. Look for fog (especially at the coast) on Saturday night into Sunday morning. I’m skeptical of rain chances Sunday. Rather, I suspect we’ll see clouds and/or fog in the morning gradually yield to sunshine, with temperatures warming into the 70s. A weak cold front on Sunday will allow temps to drop back into the 50s heading into Monday morning. More fog is possible at the coast Sunday night.

Mixed weather this weekend, but nothing too extreme ahead

The onshore flow has kept temperatures generally in the 50s across the Houston area this morning, and as a result we’re seeing the development of some fog across the area, although visibilities for the most part remain OK.

Thursday

We should see partly sunny skies later this morning, and this will allow high temperatures to climb into the mid- to upper 70s, with Houston possibly seeing its warmest day of the year. As moisture levels rise and a front drops out of the north, we may see a some scattered, light rain showers this afternoon, evening, and during the overnight hours. However anything that forms should not be threatening. The front itself could reach the northern part of the metro area by or before sunset today, and move through the region during the overnight hours.

Dewpoint temperatures for 6pm Thursday evening show much drier air behind the front, and the coast still remaining pretty humid. (Weather Bell)

Friday

Any rain should end after the front moves through, and we’ll be left with a chilly day Friday as northerly winds blow in, and highs struggle to climb above the mid-50s. Mostly cloudy skies will add to the winter-like ambiance.

Weekend forecast coming into better focus for Houston

Clear skies have allowed temperatures to cool down this morning, and more importantly they’ve afforded most of the region a good view of the total lunar eclipse. The Earth passed between the Sun and Moon just as the Moon set, and Sun rose over southeast Texas on Wednesday morning.

Wednesday

Southerly winds have returned to Houston, and this will allow temperatures to climb today to about 70 degrees under partly to mostly sunny skies. All in all, it should be a fairly pleasant day for the region, with temperatures tonight 10 to 15 degrees warmer than Tuesday night.

Thursday

Thursday will be even warmer, with highs in the mid-70s as southerly winds draw in warmth to the region. Some scattered, light showers are possible during the afternoon, evening, and overnight hours as a cool front approaches the area, and moves through. It should be off the coast before sunrise on Friday.

Thursday will be one of the warmest days of the winter in Houston. (Pivotal Weather)

Friday

A much cooler day, with mostly cloudy skies and highs generally in the upper 50s. Winds will be out of the north, but I don’t think they’ll be too gusty like they are after some cold fronts we get. Lows Friday night should fall into the 40s for most of the region.
