you can get a meteogram from HGX , just enter your City, ST or zip then click on the Hourly Weather Forecast image

best to stay alert with all media though, I'll probably be glued to this board - I'm hoping they let our youngest son off work early so he's not on the road in icy weather

What is still missing to make this an all-snow event? Is it timing of the precip and temp drop combination?

[christinac2016]

The NWS has precip stopping sometime Tuesday afternoon. Was that always in the models / plans?

HRRR and Texas Tech model blend would be a storm we would talk about for a while. The H would be a ghost town.

Late afternoon to evening north to south has been the forecasted timeframe

It's interesting but the HRRR only goes out 18 hours so I'm not sure how it stacks up for Houston as the model output ends before the main event begins but it does appear the snow is far more widespread to our north. I'm worried about the infiltration of dry air though.

Latest HRRR (Rapid-Refresh 3km High-Res)

That model appears like a widespread mess in the making for the area with heavier snow showers inbedded!

Blake can you explain the dry air concerns you have.

Winter Storm Warning coming for areas basically along and N of I-10 including Harris County. Winter Weather Advisory continues for areas S of Houston. Main concern is a mix of all forms of winter precipitation throughout the day tomorrow causing travel issues on our roadways. A Hard Freeze Warning is likely for early Wednesday, but that will be addressed tomorrow.

[TexasMetBlake]

Winter Storm Warning on the way for Harris County. Just fyi...

[srainhoutx]

Mesoscale banding is the main reasoning for the upgrade that is showing up in the model schemes. That suggest higher totals that meet Winter Storm Criteria. I believe that is a very prudent call considering all the data I've seen today.

Who issues watches and warnings for the golden triangle? Lake Charles?

Yes

This could end up being the biggest winter storm we've seen in a long time here.One interesting thing about this storm is the fact that the temperatures will not be as borderline as most of the winter events we have had over the last decade, which could yield higher accumulations.
