May 2011 Review
Spring is a transition season, and May had all the markings of a strikingly swift transition from winter to summer. The month began with heavy rain and some of the coldest daytime temperatures ever recorded during the month of May. The mercury topped out in the 50s across much of North and Central Texas on May 2. McKinney could only muster a blustery high temperature of 49°F. Temperatures took several days to climb above normal, at which point Waco set record highs on consecutive days. The heat and humidity set the stage for severe weather on May 11. Winds gusted over 50 mph along the leading edge of a squall line when it blew through the Dallas/Fort Worth Metroplex. The event brought another dousing of much needed rainfall. Another week of below normal temperatures followed before a week of stormy weather provided more rainfall. The stormy week was highlighted by a significant severe weather outbreak. Tornadoes, damaging wind, and very large hail impacted Dallas/Fort Worth and surrounding areas. More information of the May 24 event can be found here. The month ended with well above normal temperatures. Waco recorded two more record highs, including the city's first 100-degree day of the year on May 28. This was the 7th earliest occurrence of triple digits. Breckenridge reached 108°F on May 27 and 109°F the following day. Precipitation totals for the month varied widely. Above normal totals from Dallas/Fort Worth to Sherman/Denison and Paris were sufficient to end the drought, but intense drought conditions persist elsewhere.
