More snow than the last few runs. Unlike some of the other Globals, ICON does distinguish between ice and snow.

It seems like some of the models have trended south a bit today with the snow. Nice to see!

If yall don't send me snow in the next 8 days I'm leaving the board...LOLOL

Light freezing rain looks like it needs to be added to the forecast tomorrow for extreme western and northern parts of the viewing area.

Oh boy. Nearly half a foot of snow in the 18z GFS within miles of metro Houston.

Good news is it has been going more south each time so there's that

Will likely have to watch for mesoscale banding setting up here and there with the Monday system. Just like the one a month ago that hit central Tx, there will be heavier bursts in the bands with quick accumulation of mainly sleet and some snow too where the thermal profile is colder.
You can see the multiple streaks of pinks in the accumulation map of the GFS.

At least some of it is snow according to NWS, which for the first time has introduced snow into the forecast for SW Houston on Wednesday night as well:

Wunderground has about an inch of ice and snow for SW Houston Sunday night and another inch of pure snow on Monday am.

I barely touched 40. What's just 25 degrees between friends?

Just wait until the short range meso models crank up. This is going to be wild!
