Late winter whiplash continues into this weekend

I’m going to start today’s post with a bit of controversy: February of this year wasn’t that bad of a month when you compare it to February 2018. Believe it or not, 74.3% of all hourly observations in February 2019 had some form of overcast reported. That could be fog, low clouds, high clouds, or even thin clouds with a little sunshine still getting through. But it’s a nice barometer of how cloudy the month was. Guess what? In February 2018, we managed to do 81.9% of all hourly observations in some form of overcast. So as bad as this past month was, it wasn’t quite as cloudy as last year.

February 2019 had some form of overcast almost 75% of the time, which was somehow not as bad as February 2018, which managed that over 80% of the time. (Iowa State University)

February 2019 also ended up with only 1.73″ of rain officially at IAH Airport (Hobby had 3.29″). Last February saw 5.73″ of rain officially. So despite our many days of rain this year, it was actually wetter last year. But last February averaged 62.5°, while this February averaged 59.7°. So I’m giving the edge to this February for being the worse of the two months on the colder weather alone.

Today

Whatever the case, February is in the rear view mirror, and it is now onto March, which will come in….as February ended. Expect a lot of low, dreary cloud cover today. Showers are possible, but not likely. More likely will be patches of drizzle at times.

Temperatures will be the challenging part of the forecast today. That cold front from yesterday was supposed to return back north today as a warm front. That appears to not be the case, so expect a mostly chilly start to the month today. Model guidance says we will get into the low- to mid-60s later today. Given our starting point this morning in the mid-40s, I would not be shocked to see us struggle to get into the upper-50s by evening and then continue a slow rise to near 60° tonight. Either way, we’ll get there. It’s just a matter of whether it’s today, tonight, or Saturday morning.

Rodeo weather


I think we are in good shape for the rodeo tonight in terms of rain chances. Yes, I cannot entirely promise there will not be a shower, but I think that would be rather unlikely. Temperatures are another matter. Expect mostly cloudy and cool, damp conditions. Temperatures will probably be about 56-59° in the early evening and post-show temperatures should be, well, in the 56-59° range. Temps won’t move much during the evening. Watch for areas of patchy fog on your drive home, especially if you’re heading southeast of town.

Saturday

I don’t expect much serious weather Saturday, aside from areas of dense sea fog developing once again. Coastal and Bay Area communities will likely be plagued by fog once again late tomorrow and tomorrow night. The rest of us should see mostly clouds, again, though a few scattered showers will be possible through the day, especially along or north of I-10. Temperatures will continue to be difficult. South of I-10 stands the best chance at being quite warm tomorrow with highs near 75° or so. Those chances of warmth get smaller as you go north. Some places north of I-10 tomorrow may not get above the low- to mid-60s. It’s possible that at some point tomorrow Conroe is around 60°, while Pearland is sitting at 76°. It will be that kind of day.

Huge temperature difference across Houston amid stalling front

This week continues to deliver a messy forecast for Houston, as a cold front pushes through the region today, and the potential for some more thunderstorms later this afternoon and evening when upper level winds favor the development of some fast-moving showers. This rainy pattern continues through Sunday, after which time we might finally see some clearing skies with a significant cooldown.

Thursday

The aforementioned cold front is hung up in the city, such that temperatures in The Woodlands, Tomball, and Katy are only in the upper 40s this morning, while areas like League City, Seabrook, and Clear Lake are in the mid-60s with high humidity and fog.

This front should slowly slog down toward the coast this morning, helping to clear fog and dropping temperatures. Alas, this is a shallow front, so we’ll still see mostly cloudy skies. Moreover, a feature known as a jet streak, which is part of the jet stream where there are stronger winds, will transition over the region later this afternoon. This lift will bring an elevated risk of showers and thunderstorms from around noon to sunset. Accumulations likely will be only a few tenths of an inch of rain, but some small hail is possible.

Rodeo weather


I’d expect any storms that develop this afternoon to hopefully die down around 6pm, so rain chances going into the rodeo will likely be only around 20 percent. But it will be chilly, with temperatures in the low 50s, and a moderate northerly breeze. Post-show temperatures will probably be around 50 degrees, with only a 10 percent chance of rain.

Friday

As Thursday’s front, which should stall just offshore, moves back inland we’ll see temperatures quickly recover to around 70 degrees on Friday, with fog in the morning and humidity. At least rainfall chances are relatively low, probably below 20 percent.

After heavy rains Tuesday comes fog today, with more uncertainty ahead

Storms on Tuesday afternoon and evening proved more intense than anticipated, with some areas near Rosenberg, West University Place, Pearland, Friendswood, and Clear Lake seeing 2 inches of rain or more, and Deer Park and La Porte seeing 3 to 4 inches of rain. Fortunately, this threat of heavier rain appears to have passed—although daily precipitation chances are likely to remain with us through Sunday. It’s a messy forecast, so let’s jump into it.

Wednesday

The main problem this morning is fog, as warm air in the 60s moves over cooler water. A dense fog advisory is in effect until 10am this morning so take some extra care for your commute, or trips around town. Today will be fairly warm, with highs in the mid-70s under mostly cloudy skies. We probably will see some scattered showers develop this afternoon, although I don’t expect them to be nearly so organized or as intense as those on Tuesday evening.

Rodeo forecast

Temperatures will still be in the low 70s at around 6pm today, and we cannot rule out some showers over the central Houston region. I’d put the chances of light rain near NRG Stadium at about 30 percent going into the show. Conditions will still be muggy after the concert, but rain chances should fall down to around 10 percent.

Thursday

The will-it or won’t-it make it cold front appears likely to stall somewhere over the Houston metro area on Thursday. Of this much, we can be sure: a cold front will push into the northern edges of the metro area on Thursday morning. After this, the most likely scenario is that the front stalls somewhere along Highway 59, or perhaps a bit closer to the coast. Your local temperature, humidity, and rain chances are all going to vary Thursday depending on how far the front makes it (for example, the range of possibilities for afternoon temperatures at Bush Intercontinental Airport in the European ensemble model range from the upper 50s to 75 degrees). So our official forecast is ¯\_(ツ)_/¯.

Widespread showers likely today, then warmer through Friday

It’s a cloudy, misty morning generally in the 50s across Houston this morning, and overall this will be a wet day. Most of the rest of the week, and the weekend, will also be gray although rain chances probably won’t be quite so high as today. If you’re wondering about seeing some sunshine, there’s a bit of hope for Thursday, but Friday is probably the day you’re looking for.

Tuesday

The combination of a warm front moving onshore, nearby low pressure, and increasing atmospheric moisture levels will lead to a day of widespread showers and perhaps a few thunderstorms. As we saw on Monday, there is a chance of seeing some small, likely pea-sized hail in the strongest thunderstorms. Most of the region will likely see 0.25 to 0.50 inches of rain as highs rise into the mid-60s under gray skies. Will it be humid? Oh yes, it will be humid.

Rodeo forecast

On Monday, we saw rain showers diminish as the gates opened at 6pm for NRG Stadium and the Houston’s rodeo. I’m not sure that will happen tonight. It does appear as though the rain will lift north and east of Houston this evening, away from the city, but it’s not clear whether that will happen by sunset, or a little bit after. We’ll therefore carry rain chances of about 40 percent going into the show, and 20 percent after.

Temperatures will be in the low 60s at 6pm, and largely unchanged later on. With dewpoints nearly the same, expect 100 percent humidity. By the way, at the end of today’s post, be sure and check out a special message from Reliant about it’s rodeo-related activities.

Wednesday

Rain chances will be lower on Wednesday, perhaps in the 20 to 30 percent range, as the atmosphere calms down a little bit. Temperatures will reach the 70s, as warmer air moves into the region from the south and southwest, and Wednesday night (mostly if not completely dry) will only fall into the 60s.
