Apparently, that would be indicative of significant accumulations (an inch or so). If it happens, that's the sort of snow event that hits Houston once every 30 or so years (I haven't seen an inch or so accumulate near the airport since the 80s). The Christmas Eve snow of 2005 and last year's Snow barely dusted the North Side. It was areas around Sugarland and Baytown that got dumped on for those.

From what I've read, there's supposed to be an upper-level low approaching S.E. Texas on Friday morning, and the precip associated with it will be riding through a solid column of cold arctic air that the frontal boundary currently over North Texas is dragging into the state. Thankfully, the solid column of cold air will likely mean that there won't be much in the way of ice/sleet.

Not unheard of for a low near the moisture-rich Gulf and a blanket of arctic air to create impressive snowfall totals along the Texas coast. A similar set-up in 2005 resulted in areas around Victoria (closer to Corpus Christi than Houston) receiving about 14" of snow. IIRC, it topped their all-time one-day snowfall totals by about a foot. When I was in Corpus Christi for the August Baseball DO, there were shops selling postcards showing the Palm-lined shore of the bay buried under about 3" of snow.

Still 48 hours out, so definite forecasts are too hard to pin down at the moment, but there's definitely some support in the models for a decent amount of snow on the North side of town.
