A wintry morning, but a milder weekend ahead

Wintry weather in Houston doesn’t tend to last too long, and this will be another case where we escape the chill rather quickly. That said, we have an interesting extended range to watch. Some words on that in just a bit.

Today

As I write this, the official temperature at Bush Intercontinental Airport is 38 degrees. Looks like Houston will officially bottom out around 36-37°. The freezing line is well north of the city and should just get to about maybe Conroe. A few rural pockets on either side of Houston could briefly touch freezing before 7:30-8 AM.

Overall, no big deal in the city, but certainly a light freeze to the north. Now, all that said, it feels unpleasant out there this morning. It’s still breezy, with winds gusting to about 15-20 mph at times. Wind chill values are in the 20s across much of the area. And it will take a few hours this morning before it feels a little nicer.

Temperatures will warm up to the mid and upper 40s this afternoon, with a variable mix of sun and clouds.

Weekend

Overall, this weekend will be neither the best nor worst weekend we’ve ever experienced. Saturday will feature a few changes in the atmosphere: More onshore winds, gradually increasing humidity, and increasing clouds. We’ll start the day chilly again. There is a slight chance that temperatures could again push freezing north of Houston by tomorrow morning. Model guidance is a little more bullish on that risk than I expected this morning. Expect mostly upper 30s to low 40s south of Houston, with low to mid 30s north. A freeze in the city itself is unlikely, but areas outside the Beltway could come closer than this morning if clouds hold off. Saturday afternoon will press into the low to mid 50s with cloud cover. Temperatures probably won’t drop much Saturday night, and in fact, they may continue to rise to near 60 on Sunday morning.

Sunday itself should be a bit dreary. We’ll have clouds and a few showers or sprinkles around. Temperatures continue to edge upward to around 70 degrees by Sunday afternoon. I wouldn’t be shocked to see issues with fog near Galveston by Sunday or Sunday night.

Overall: Your weekend plans are all a-go, but Saturday will be a little nicer (albeit cooler) than Sunday.

Next Week

A weak cold front will slide through Monday, kicking showers away temporarily. But the front will quickly lift back over us as a warm front, continuing the mild weather into Tuesday and Wednesday, along with a low-end shower chance. So we’ll see no wintry weather to start the week, but what about later in the week? Well, it’s complicated. Here’s the forecast of air temperatures about 5,000′ up next Thursday.

There’s definitely going to be a cold front mid to late next week in Texas. The question is whether it will have enough “oomph” behind it to really press cold in here. The one thing to notice from the map above is the tight temperature gradient. In other words, the change in temperatures over a small distance is great. You quickly go from near or above normal to sharply below normal. So trying to iron out details seven days out is difficult because small shifts in the forecast can mean big temperature changes. This battle continues into next weekend, with a warmer Texas and a frigid northern U.S. Wintry weather is certainly here, and unlike last year, there’s a good deal of cold air to work with. This first real cold blast we’re experiencing this morning will certainly not be the last for Southeast Texas, so stay tuned.

Houston under a Flash Flood Watch through Sunday

Good morning, everyone. The National Weather Service in Houston has posted a Flash Flood Watch for the entire region through tomorrow evening. As expected, conditions will become more favorable for flooding to occur in the hardest hit parts of the area as we go deeper into today, tonight, and tomorrow.

Rainfall since yesterday afternoon across the area has been mostly manageable to this point. Northwest Harris County has seen 1-3″, while central and southeast portions of the county have received about a half inch to perhaps up to 1.5″ of rainfall.

An average of about 1-2" of rain has fallen over much of the area since yesterday. (Harris County Flood Control)

Outside of Harris County, Galveston has already set a daily rainfall record for today with over 4″ reported as of the 8 AM observation.

A damp December weekend descends on Houston

It certainly has been awhile, but a damp and stormy weekend is on tap for Southeast Texas. Let’s break it down.

First off, one more hearty thank you to Harmony Strings for sponsoring this site this month!

Today & Saturday

We’ll be quiet for most of the morning today, but clouds will gradually thicken up overhead. Rain showers should begin to break out to our south and west by midday, spreading north and east through afternoon.

Short term HRRR model shows numerous showers developing across Texas today. Some will move into Houston later this afternoon and tonight. (Weather Bell)

A patchwork of scattered showers should be strung out around Houston by the evening commute.

This means that the Christmas tree lighting forecast in Downtown Houston isn’t looking fantastic right now. That said, if the HRRR above is right, we may be able to get it in without too many issues. If you are planning to go, make sure to double check the city’s website or social media feeds.

It may be a bit damp at times for the tree lighting tonight in Downtown Houston

 

Periods of rain and perhaps thunderstorms will continue throughout the evening and into the overnight hours. We may see heavier rain along and north of I-10 toward morning. That may pivot toward Houston more tomorrow. Basically, the whole area will see rain, heavy at times, and thunderstorms at various points through the day Saturday.

A forecast caution here: Yes, it will be a stormy couple of days, but it probably will not rain in your neighborhood the whole time. This type of rain will come in fits and starts. Trying to time exactly when and where we see the heaviest rain is exceptionally difficult more than 12 hours in advance with storm systems like this.

A splendid weekend ahead

Good morning! Hopefully you had a splendid Thanksgiving and aren’t still stuffed after yesterday. I may be. But I have an appetite for a forecast, so let’s hop to it.

Today & Weekend

We are in a holding pattern right now between Wednesday’s front and the next system waiting for us next week. That means the weekend will see nice weather for the most part.

Today will be pleasant overall, but a bit gray at times. We may have a couple showers or sprinkles, around the area, but otherwise it will be a mix of clouds and some sun. High temperatures will hit the low 70s.
