In response to some friends on S2K:

I'm glad some of y'all are enjoying the snow. I hope we get some on Thursday as a parting shot. It's looking a little better on the HRRR.

In the meantime, I am closely watching temperature trends for the ice storm about to impact SE and East Texas. It's going to be just epic for some folks to the North and especially NE of here. We are right on the edge. A serious demarcation between ice and rain, and thus, the accumulation totals. The HRRR keeps going back and forth between a little ice nuisance and the ice storm apocalypse for me in southern Montgomery County, so it's just waiting and watching the temperature/dew point spread until it starts falling down over here.

FWIW the 0z GFS looks similar to the 0z NAM showing heavy freezing rain down to I-10. I don't like how low the dewpoint still is,when rain starts temps are going to easily fall below freezing unless the dewpoint starts to rise over the next several hours.

Hey everyone, been a busy couple of days. How is everyone doing? I hope those without power have found ways to stay warm! We just need to get through Thursday and we should be in the clear.

Doing good. Making al pastor tacos in the backyard. Electricity is on, but I'll take no chances to miss a warm meal once the power goes out again :D

The coast has warmed significantly. Look at Galveston and Bolivar - in the 40's, while areas to the NW are below freezing. As the low deepens, the temperature gradient will deepen too.

Spring here...does this mean a small window for freezing rain for the northern parts of the county?

If you mean Harris county, it depends on how far east or west you are. The line is generally along 59, but with the low where it is, it has a steep arc to it.
