Hello all, sounds like it’s been a decent January for you. I really thought this storm would trend north based on history with these systems. Boy was I wrong! I realize there is a dedicated thread for this but I wanted to share this here (mods please feel free to move if needed). Below is part of the MOB AFD from this afternoon. It’s certainly something I never thought I’d see. We are less than a mile from the water so I’m sure we’ll have some mixing issues. Sorry for the long post and the lack of relevance!

Winter Storm Likely... A potentially significant winter storm is
expected to affect areas along the northern Gulf Coast on Tuesday.
At this point, the "dry scenario" is pretty much off the table, and
with high probabilities suggesting that much of the area will see at
least 1 to 2 inches of snow, the entire local area is now under a
Winter Storm Watch from 6am Tuesday morning through 6am Wednesday
morning. Although there are still some precip-type uncertainties
along the coast, this will likely be an all-snow event for much of
the local area. Along the coast, there may be just enough of a warm
nose around the 850mb level to allow for some sleet pellets to be
mixed in. Otherwise, looking at temperature profiles prior to the
onset of precip, the dendritic growth zone looks to become fully
saturated by around 09z-12z overtop a very dry 0-1km layer. Precip
should initially start off as virga, or as very light flurries. Over
the following couple hours, the dry lower levels will begin to
moisten and cool (due to wet bulbing effects), likely bringing
surface temperatures/dew points into the 20s. By this point, heavier
snowfall rates will become realized and due to the colder
temperatures at the surface, snow will start to accumulate. Looking
at ensembles, the probability of accumulated snowfall greater than 3
inches continues to increase in comparison to previous days.
Probabilities now stand at roughly 40 to 60 percent, which is why we
are becoming increasingly concerned that this will be a significant
event for the local area. If snow amounts over three inches actually
occurred at KMOB, this would place us in the top 5 for historic
snowfall amounts on record for the site. If three inches of snow
occurs at KPNS, this would be actually be the highest accumulating
event since the late 1800s! It should also be noted that
probabilities have been pushed further to the south over the past
couple days, with the best probabilities lining up around the I-10
corridor. Although there could still be some more minor fluctuations
to where the heaviest snowfall will occur, these trends could lead
to some major problems along our coastal counties. We urge residents
and visitors to continue monitoring the forecast closely over the
next few days and to begin preparing for this event.

Winter Storm Warning is out for Houston! Enjoy Don! It certainly has not been the Winter that a lot of Long Range Prognosticators led us to believe!

I'm heading that way in the morning. I figure the roads should be fine 

Yeah doubt there'd be any problems, especially on main roads with the wind blowing this powder around. A lot of the county has a light dusting already at this point, with even a bit more in a few higher elevation spots sitting just right in the flow.

@NavarreDon  If I was a MET I would have added another paragraph at the end of that statement.  Something like:

 Please keep in mind that we are talking about a storm that will most likely give us 3” of snow with some pockets of 6” possible. Roofs are not going to collapse and there will be no avalanches sweeping us into the Gulf.  As mentioned above it has not snowed this much in this area in over 100 years.   Layer up with sweaters and jackets, walk outside and enjoy something you will most likely never see again in your lifetime. Have a snowball fight, build a snowman, just take a walk and enjoy the sights with family and friends.
