After another active weekend of severe weather, stronger storms and flooding look to be on tap for many of the same areas this week.
A higher severe weather potential could return this weekend as an area of low pressure is likely to move out into the Plains, triggering possibly more severe storms from Iowa through Texas.
In addition, as has been the case over the last few weeks, the shorter-term threat will also include the potential for flash flooding across parts of the South that have been inundated with heavy rainfall over the last few weeks. Most of Texas and Oklahoma are well above average rainfall-wise for May and the spring overall, helping alleviate drought conditions in western parts of both states, but more rainfall could lead to more flooding across the region. Oklahoma City, Oklahoma has received 12.85″ of rain so far in the month of May, far above the month-to-date average of 2.42″.
May is typically the most active month of the year for severe weather and specifically tornadoes, with an average of about 275 tornadoes across the U.S. While the tornado threat for much of the work week appears to be lower, it could ramp up by Friday and particularly by Saturday as a persistent pattern stays in place. That pattern – a trough of low pressure in the western U.S. and a ridge of high pressure in the east – often leads to severe weather due to areas of low pressure moving into the Plains, where warm, humid and unstable air clashes with cooler and drier air drawn in from the low.
