Records Fell Like the Summer Rain that Never Came

Records fell like the summer rain that never came How to read the chart Record highs Daily highs -. Normal highs 1 2011 began with an early-February Arctic blast that caused problems statewide, including school closures, rolling blackouts and less-than-ideal conditions for the Super Bowl in Arlington. 1The cold didn't last long, however, and soon gave way to month after month of record-high temperatures, devastating drought, and scorching wildfires. 1 In all, Houston had more than 60 daily temperature records tied or broken. After seeing only two 100-degree days in 2010, the city endured 46 days at or above the century mark in 2011, including most of August. 1 The drought, which had been brewing since 2008, peaked in October, with nearly the entire state suffering in the "exceptional" category. Rain returned at the end of the year, but the drought is far from over.
