Three winter storm complexes will move through the region.

The first of the 3 systems will be arriving early Saturday evening
and overnight. Near freezing temperatures will be in place with a
threat of freezing rain and sleet. Precipitation amounts should
be light but even so icy roads will be issue especially along and
north of a line from Bellville to Conroe to Livingston.

The second system is likely to bring record-setting cold to the
region.

* Bitterly cold air will be moving into the region behind an
Arctic cold front Sunday night into Monday morning. Temperatures
will abruptly plummet below freezing with strong gusty northerly
winds.

* Freezing rain changing over to snow is likely with this system.

* Prolonged periods of freezing temperatures are expected with low
temperatures Tuesday morning 5 to 15 degrees.

* The combination of both the cold temperatures and winter
precipitation have the potential to significantly impact life and
property.

* Travel will be severely impacted by hazardous icy and snowy road
conditions. Sporadic power outages will be a possibility. Pipes
and sprinkler systems may burst if not properly cared for in
advance. Do so now!

* You should plan to stay put for at least a day given where you
are Sunday night because travel may be extremely hazardous
Monday.

* Hypothermia will be a possibility for those not dressed
appropriately. Brutally cold wind chill readings of -7 to 10
degrees will be likely Monday through Tuesday morning.

* Remember the 4 P`s: pipes, people, pets and plants. In
addition, be aware of space heater dangers if not properly
placed/used.

The third system arrives sometime Wednesday and could bring
another round of freezing rain or snow the region and continuing
the cold weather though not as cold as Monday night and Tuesday
morning it will continue the winter hazards. Confidence on timing
and impacts is lower on this system given the potential for an
extensive snow cover to be present across the Southern United
States and the potential feedback into the third system.

Thanks Cro. If this hasn’t grabbed your attention yet, that should definitely get some attention. Unbelievable wording in that statement.

Things are about to get real

Snow is on the way for Houston. Ch. 11 keeps it in the forecast not only for Monday but for Wednesday and Thursday as well.

12Z ECMWF suggests a bit colder with snow from the Monday storm.

[txsnowmaker]

It’s happening!

[txsnowmaker]

Oh boy. Shows even more after a Wednesday/Thursday system.

Does this also include sleet totals? Thanks!

It looks to me like it’s trending south though on each passing run. And keep in mind the Euro has been doing pretty horrible with temps so you can probably expect temps to be even colder which could lead to even more snow.

[Cpv17]

Y’all just wait for the 12z eps map to come out here shortly. Bet it’s gonna look pretty nice!

Guess it depends where in the viewing area you are. I’m in SW Houston and am impressed.

I'm impressed enough. The cold has been outperforming predictions over the last 4 days.

[txsnowmaker]

Icon is off. There will be snow in Houston.

That’s because it doesn’t include ice and sleet which is mainly what people south of I-10 will see.
