The rain which fell Wednesday into Thursday night was one of the most widespread and heavy rain events our region has seen in months.  LCRA’s Hydromet and Doppler radar estimates showed much of the Hill Country received between 1 and 2 inches of rain while totals were generally between 2 and 3.5 inches across Central Texas.  The middle Texas coast received anywhere between 1.5 and 6 inches of rain.  LCRA’s highest gauged total was 6.94 inches at Glen Flora, in central Wharton County.

NWS Estimate of Rain Falling Between 9 am Wednesday and 9 am Friday:

December’s wet weather significantly changed the annual rainfall totals.  What was shaping up to be a very dry year before December, ended up being a calendar year with near normal to just slightly below normal rain totals.  Southern Travis County, eastern Hays County, Schleicher County and most of Wharton County showed rainfall amounts that were above normal.  Meanwhile, rain totals were well below normal across Fayette and Williamson Counties along with much of the southern Hill Country.
