Do you have a link and/or can you expand on what it shows for Houston?

00Z GFS goes absolutely crazy Monday night with the upper-level flow and having cold air stream south very quickly from the northeast. I remain skeptical but we will see.

If the forecast model did hold up, it would be like February 1899. :shock: :o

00z Icon, Canadian and GFS are just absolutely bonkers. Talk about consistency in the short-medium range with such extreme temps/snow/ice. Heck, CMC says let's keep the party going into next Wednesday and Thursday. I know the idea of this may be exciting for those who like to see the extremes, but this has the potential to cause some major damage not only across the state but the country. Billions of dollars in damage.

This is quickly becoming very concerning and a major disaster. I've never in my career seen models forecast this type of cold here, ever. I was too young to remember 1989 but this goes beyond 1989. This is more along the lines of 1899 or worse. I'm very concerned about the potential for a prolonged sub-freezing stretch with single digits and teens. 1930 holds the all-time low of 5. Do we challenge that? It's possible I suppose if we have an abundance of ice and snow on the ground and skies clear. Mercy.

Take a deep breath y'all. This is unbelievable. Truly, unbelievable.

I am thinking February 1895 and February 1899.

February 1895 had 20 inches of snow. February 1899 was an epic freeze.

WOW. Ive was born and raised in Houston-and still live here. I recall 1989 vividly. It was like 9 degrees and must have been couple of inches of ice outside. But this...looks worse-Im concerned about tree limbs etc around the house...power etc

Here's a look at the raw GFS output for IAH. Highs in the 20s and a low of 9 degrees. Not quite 1989 but darn close.
