SUMMARY OF CLIMATOLOGICAL DATA
Like in March 2011, April 2011 saw a mix of above and below normal temperature averages as well as a mix of above and below normal rainfall totals.
That aside, the tornadic outbreaks during the month across the entire three-state area certainly were the highlight weather events. As many of you noted, it's difficult to remember - especially for those of us who have been keeping weather records for 30, 40, and 50 years - such a high level of severe weather with the degree of tornadic development that we saw this month (that grew even worse in May for the nation's midsection). The unusually severe weather was noted early in March across the nation's midsection and south; but rarely do we see that pattern migrate this far east so soon in the year. Many have noted the prolonged cool temperatures remaining over the northern half of the United States while the usual surge of warm and humid air moved into the southern extremes of the prolonged chilly temps. The contrast between the air masses created a persistent boundary zone that combined with an aggressive jet stream to fuel the ongoing tornadic outbreak. In mid-April, the tornadoes killed over 40 people across 6 southern, southeastern, and lower mid-Atlantic states. In Virginia, 5 people were reported dead in the Gloucester area as a F2/F3 "long track" tornado touched down in Surry County and moved to Gloucester. In North Carolina, dozens of twisters (over 60 individual tornadoes were reported) left over 20 people dead, with 11 people dead across Bertie County from a tornado lasting less than 15 minutes. The NWS Raleigh has its reports of the April storms archived at http://www.erh.noaa.gov/rah/news/ .
