The Heat Miser shared this on another forum. I hope he doesn’t mind it being shared. He is totally correct; especially with the potential of a vast snow/ice pack on the ground...
“ One thing to watch for, particularly in SE TX, is that second trof passing on Wednesday. Models always try to drive Arctic air back to the north too quickly when onshore flow begins aloft. That's why some have Houston rising above 32F Wed. GFS has all precip falling as rain. That won't happen if the Arctic air is still entrenched. It would be freezing rain or sleet Wednesday. Hazardous driving conditions may continue until Friday down south.” - wxman57

Is Angleton considered the "immediate coast"?

That's more like it! A nice thick blanket of snow on the roof acting as insulation.
32°F, never above freezing for the past 2 days; DP = 25°F

The liquid equivalent of that model is spitting out up to an inch and a quarter precip. Impressive!

I work for a chemical trucking company and supervise drivers and employees in the Dallas and Houston areas.
We are trying to top off hospital Oxygen tanks in the next 24 hours.
As far as Dallas is concerned we are shutting it down this afternoon, but I am going over the Houston routes for tomorrow. What time will it start to freeze/ice in the Houston area?
I want them off the roads by then.

Some of the short range guidance suggests the possibility of light freezing rain/drizzle overnight near W and NW Harris County and again in the morning. Freezing rain and sleet start to press in by around 4 PM or so tomorrow.Rip76 wrote: ↑Sat Feb 13, 2021 4:47 pm I work for a chemical trucking company and supervise drivers and employees in the Dallas and Houston areas.

So if I have them off the road by 4/5pm tomorrow, we should be fine?
