Austin / Travis County and South Central Texas Weather Statement #3

…. Potential Winter Weather Event Tonight into Thursday Morning ….
…. Computer Models Trend Not Quite So Cold Tonight ….

None at this time

Ahead of the arctic cold front.. that currently extends from southeastern Oklahoma
into north central Texas to the Waco area to north of San Angelo.. we’re seeing
dense fog and light rain with temperatures in the upper 50s to near 60 degrees. The
arctic cold front will pass south southeastward through the Austin and south central
Texas area during the early to mid afternoon hours.

A couple of things I’m seeing this morning… (1) the coldest air is lagging behind the
front with the 20s and 30s hanging back over Oklahoma – this air isn’t as cold as I
thought it would be over Oklahoma this morning. (2) Computer models over the last
24 hours have trended¬† warmer locally tonight into¬† Thursday morning. In short, I’m
not as certain today of the temperatures being as cold as I’ve been advertising for
late tonight into early Thursday morning. That being said, please keep in mind that our
numerical forecast models have a tendency to be too slow with arctic frontal passages
and tend to underestimate the intensity of cold air in these type situations.. so we need
to continue to watch the situation.

I still expect to see the 50s and lower 60 degree temperatures today fall quickly
with the advancement of the cold front this afternoon. I now expect to temperatures
to fall through the 40s as we go into the afternoon/evening rush hour. Overnight, we’ll
see temperatures fall to closer to 30 degrees by daybreak Thursday.

As the relatively shallow arctic cold air slides southward over the area, several
upper air low pressure disturbances will move across the area tonight into Thursday.
This will produce an overrunning clouds and light precipitation which will
likely persist through Thursday. A mixed rain.. freezing/frozen winter precipitation
will likely occur over parts of south central Texas based on the latest guidance. Based
on what I’m seeing this morning, I’m thinking that we.. once again.. could find ourselves
not quite as cold and more on the border of the freezing temps and the areas where
potential ice could have an effect.

While we will likely see some breaks in the clouds by Thursday night into Friday, the
cloudy overrunning pattern is likely to kick back in by Friday night into the weekend
with temperatures only slowly warming.

All local interests across the area should stay in close touch with the latest south central
Texas forecast and weather information from the National Weather Service.
