Austin / Travis County and South Central Texas Weather Update #2
Prepared by UT University/Incident Meteorologist Troy Kimmel
900am CT – Wednesday / 06 December 2017
.. Rain/Sleet/Snow Mix Still Possible to Our Northwest Over Hill Country Areas Tonight into Thursday ..
.. No Accumulations Expected ..
On this Wednesday, a surface cold front continues to settle southeastward through the Gulf of Mexico
with much colder surface based air continuing to feed into the area. At the same time, a second upper air
low pressure disturbance is moving over the area with light rain continuing in the post frontal colder air.
Temperatures with cloud cover today will remain around 40 with occasional light rain continuing through
tonight and into Thursday. Overnight tonight, temperatures will fall into the mid and upper 30s.
After sunset tonight, the rain will become mixed with some snow flakes and sleet over the northern hill country.
This winter precipitation mix may slowly spread into the higher elevations of extreme western Williamson.. Travis
and Hays counties after midnight as temperatures fall into the mid to upper 30s. Based on the latest guidance,
I do not look for any of the wintry mix to make it as far southeast as the IH35 metropolitan areas.
After sunrise on Thursday, even though the clouds and rain chances will persist, I expect temperatures to
rise back into the 40s.
At this point, I expect surface air temperatures in the counties along the IH35 corridor to remain above the
freezing mark and this will combine with warm ground temperatures to keep us problem free. Some areas of
the Texas Hill Country to our distant west through northwest.. where temperatures get a little closer to freezing..
could see some isolated and localized problems on bridges and overpasses. At this point, due to the warmer
ground, I do not anticipate any snow/ice accumulations around the area.
Once this last upper air disturbance passes, I expect clearing skies Thursday night into Friday with abundant
sunshine and warmer temperatures Friday through the weekend and into early next week.
I’ll continue to monitor this weather situation closely..
