This summer, warmth and dryness will build in the West, worsening the historical drought conditions that have plagued California for four straight years. Meanwhile, the Gulf Coast will have an abundance of moisture, raising concerns for flooding at times.
In the nation’s midsection, severe weather is forecast to continue into summer, with the overall tornado count increasing from last year. In the Northeast and mid-Atlantic, above-normal temperatures will mark a noticeable difference from the cooler-than-average summer of 2014.
JUMP TO: More 90-Degree Days Than Last Year Forecast for Northeast, Mid-Atlantic| Wet, Buggy Season Ahead for Southeast, Central Gulf Coast, Tennessee Valley | Rainy Weather in Store for Southern Plains, Lower to Mid-Mississippi Valley | Severe Risk to Continue for Midwest, Northern and Central Plains | Severe Drought to Worsen in California, Expand Northward at Full Force
Warmth from central Canada and the northern Plains will flow into the Northeast this summer, leading to above-normal temperatures and drier conditions for much of the region.
“I’m not expecting extreme heat, but periods of warmer-than-normal temperatures will come and go during the course of the summer,” AccuWeather.com Expert Long-Range Forecaster Paul Pastelok said.
After a cooler-than-normal summer of 2014, the East overall is forecast to be hit by more 90-plus degree days this summer.
In Philadelphia and New York City, there may be as many as 10 more than last summer.
For much of the summer, the central and southern mid-Atlantic will come alive with showers and thunderstorms.
Washington, D.C., Baltimore and Philadelphia will be in the line of fire.
From the Southeast to the Gulf Coast and Tennessee Valley, the summer of 2015 will bring very wet conditions as result of warm water temperatures in the northern Gulf and a building El Nino. Flash flooding could be a concern at times.
“I would consider stocking up on the bug spray this year down across the Tennessee Valley and the Gulf Coast because it looks very wet,” Pastelok said.
Extreme heat should be kept at bay, but high humidity and muggy conditions will plague the region.
As for tropical activity, the northern Gulf states could be affected as early as June.
“Water temperatures are running much warmer than last year,” Pastelok said. “It may not take much to spawn a weak tropical system to enhance the rainfall on the Gulf Coast this year.”
