So the 00z Hrrr is….concerning lol. Man, it brings a devastating ice storm to Austin and the I-35 corridor. It’s 30°F now, colder than forecast and has been all day.

Quick update: possible expansion of WWA to include San Antonio as well as areas further south and east is being monitored for the 4am update. Wouldn’t surprise me at all.

Winter Storm Watch coming shortly for Austin area. Standby.

Looks like this is the first time IAH has seen back to back years in the teens since December 1989 and December 1990. To get back to back years at or below 15°F at IAH, you'd have to go back to Jan 1982 and Dec 1983! So pretty rare!

ACT has held at 15 now for the last 3 hours. The temperature fall is beginning to slow a bit in central and north Texas. Should still see a decent drop in the Houston area for the next few hours. Dewpoints are -4 at DFW, 2 at ACT, 14 at IAH, and 4 in AUS. So still plenty of room to fall another 5 or...

19°F now. Well ahead of schedule and just about the break through GFS' paper thin prediction. ;) Blake, my 13°F prediction may be too high. Single digits could be a possibility under clear skies. The wind is the Achilles’ heel. Normally wind that strong would stifle a significant drop in temps but ...

7pm Temp Check vs NWS Forecast Low: Dallas: 14°/10° … big bust potential Austin: 21°/15° … big bust potential San Antonio: 26°/18° … big bust potential Houston: 29°/16° … potential bust Still have 12 hours of cooling ahead 👀 Temperatures are far outpacing any model and we’re already closing in on th...

The front is WAY over performing. It would not surprise me at all to see temps below 15 at IAH tonight.

Looking at the 12km NAM and the 00z GFS, I find it interesting that they are "warm" showing lows in the upper teens for central and southeast Texas while the 00z GEM and ICON models are single digits and teens. Seeing the NAM more in line with the GFS kind of raises an eyebrow for me. Maybe I'm too ...

00z GFS has my attention now, more moisture, hinting at precipitation with the front in SE Texas…… Pre-frontal. One thing that we will have to watch for is "flash freezing" of leftover water on elevated surfaces with temperatures almost immediately crashing into the 20s behind the front. This is pr...
