A persistent low-pressure system over the central United States has funneled repeated storm systems across the Eastern and Southern United States throughout the month of May, driving rainfall totals to record levels in several cities. Some locations have already logged their wettest May on record, while others have entered the top five.
More rain is expected through the last weekend of the month in the Northeast with continued thunderstorms across the southern states, likely pushing monthly totals even higher before May ends.
Several cities have seen record-breaking rainfall this May, including:
- Jackson, Mississippi: 124.2 mm (4.89 inches)
- Huntsville, Alabama: 284.5 mm (11.20 inches)
- Worcester, Massachusetts: 197.5 mm (7.78 inches)
- Johnstown, Pennsylvania: 163.1 mm (6.42 inches)
- Providence, Rhode Island: 194.6 mm (7.66 inches)
- Montgomery, Alabama: 236.5 mm (9.31 inches)
Although May’s insistent rainfall was helping to balance out the earlier dry spells in the Northeast during March and April, the frequency and amount of rain are now having a negative effect on agriculture and the construction industry.
“Some places have received double or more than their historical average for May in New England, as well as portions of the South,” commented AccuWeather Senior Meteorologist Brett Anderson.
