with the cold air dropping temperatures into the 20s and 30s across most of the area. The first of several frozen

precipitation events occurred on the morning of 11 February where up to 0.75 inches of freezing rain

accumulated on surfaces in Llano and Burnet Counties and 0.25-0.50 inches of freezing rain accumulated

across the Austin metropolitan area with lesser amounts in portions of the Hill Country and New Braunfels

area.

With the cold arctic air mass still in place and temperatures still below freezing, another upper level

disturbance approaches from the west. Ahead of it, warm air aloft led to freezing rain across the Hill Country

and I-35 corridor on the evening of 16 February and into the morning of the 17

up to 0.25 inches of additional ice accumulation, with higher amounts of up to 0.6 inches of ice on already iced

or snow-covered surfaces. Meanwhile, the upper disturbance sent a reinforcing cold front into the area the

evening of the 17

spread east and transitioned to all snow by the following Thursday morning. Significant record snowfall

failed power grids, burst water pipes, and limited road and air travel.
