Confidence is increasing for a freezing rain/sleet event in
the Houston area starting late this evening in the far northern and western
suburbs and then for the immediate Houston area southward during the early
morning hours.
This will likely have a significant impact on your Friday
morning commute.  Most of the road surface temperatures in the
Houston area will be much too warm for any potential ice accumulations.Â
However, any exposed elevated surfaces (bridges, overpasses and flyovers) will
quickly glaze over as temperatures approach freezing or lower and will be
extremely hazardous. Â Â This will include but are not limited to some
of the major interchanges joining 45, 10 and 59 with the Sam Houston
Tollway.  In the past, even minor accumulations of ice here have
resulted in total closures.  TDOX has been applying an anti-freeze
solution since last night to many of the area’s bridges and overpasses and they
are continuing those operations today. 4951
