This pattern of the iPhone weather app showing far worse air quality than the official observation stations continues.

I did some research. The air quality data in the iPhone weather app is supplied by a company called “Breezometer”

https://www.breezometer.com/products/air-quality-api

Never heard of them so I can speak to the accuracy of this data. It is perplexing and at the same time intriguing. I would bet the air quality shown at the street level (worse from traffic) is the real deal. I’m not sure how they are collecting this data (satellite measurements maybe) but it certainly makes me wonder how accurate it is.

I use a website call AQI. I think they have an app. Its based on ground level sensors.

I used the website when I was working in China. The levels got to extremes at time, (450Pm 2.5) at which time our company wouldn't let us leave the office or they would bring us back to office.

Mesocale models like the NAM 12km are getting in range of the initial blast of arctic air, already much colder and faster than the op models with precipitation breaking out

I was literally just about to post that lol

Any winter fun for us in SETX?

Not looking likely

Maybe for our NW counties, but unlikely in the houston area, the setup is not supportive for snow, this will be either rain for some and Ice for others

What kind of temps for us then?

highs in the mid 40’s

like I said the other day.. grasping for straws at this point for S.E. Tx. Season is winding up. February might be coldish but its time to face the music, folks. Get geared up for spring.

we arent grasping for strolls lol winter is coming back and its sticking around

Sounds like we will have some cold here. I agree with you, Stratton.

Next week’s forecast is going to be very difficult to figure out. The mesoscale models are gonna have a much better idea. The globals are clueless.

You should work on being positive in life. It’s healthier for you.

we are within range of the NAM 12km, and i can tell you its already faster and a good 5-10 degrees colder than the operational models , thats something to keep in mind, as the mesocale models handle the shallow arcitc airmasses by far better than global models do

No surprise. Actual temps even now in CLL have been about 5°F colder than progged. We've had 2 freezes in a row.

I expect ice/sleet next week is very possible up here in the NW territories.

NAM is in close agreement with the Canadian for now...and should continue on that general trend as Feb 1 comes into range.

hmmmmm...the Canadian is sniffing out a Baja ULL heading our way in the latter half of next week... when cold air *could* prevail in NW counties against the SE ridge. Stay tuned.

The ensembles have trended even wetter today compared to yesterday.

Cpv17 yep! Its looking even better for sure
