Warm weather fans across much of the East rejoiced this week as seasonable warmth and sunshine returned to the region following a cool and unsettled Mother’s Day weekend.
This sunshine, when combined with relatively low humidity made for several beautiful days for residents along the East Coast to soak up springtime warmth. However, AccuWeather forecasters warn that this fun in the sun is set to be dampened, due in part to a pesky storm currently churning off the coast of the southeastern United States.
“While it’s still spring, a non-tropical area of low pressure currently located offshore will move through the Southeast from Friday through the weekend and bring a more summery, tropical feel to the region,” AccuWeather Meteorologist Randy Adkins said.
With the arrival of this area of low pressure, moisture currently located out over the Atlantic Ocean will be pushed inland and work to increase clouds, shower chances and humidity levels for a large portion of the East.
As the week progresses, showery weather will expand outward from the immediate coast and into more of the interior East. By Friday, showers can occur at times across a large swath of states that includes areas from northern Florida to central Pennsylvania and part of northern New Jersey.
To start, this upcoming “tropical feel” to the weather will largely be driven by a significant increase in humidity across the Eastern states, not necessarily above-average heat.
Humidity is what meteorologists use to describe the amount of water vapor in the air. Higher levels of humidity can lead to the air feeling “sticky” or “thick” due to sweat having a more difficult time evaporating from a person’s skin.
For many residents in the East, especially in the Northeast, prolonged periods of humid air have been hard to come by so far this season. That will change by the end of the week.
“The higher humidity will be more reminiscent of mid-July as opposed to mid-May,” Adkins said.
Higher humidity, or more water vapor in the air, is also an ingredient that can work to trigger thunderstorms in a situation like this, according to forecasters.
By the weekend, the threat of embedded thunderstorms within the larger area of showery weather will increase as moisture surges farther north and west.
The swath of wet weather will expand to reach a much larger area that includes portions of the Tennessee and Ohio valleys, the Great Lakes and the Northeast.
“It certainly won’t be as chilly as last weekend, especially in the Northeast, but there will be showers around and folks will need to keep an eye on AccuWeather’s MinuteCast® to discover when they can get some dry time outside this weekend,” AccuWeather Meteorologist Dean DeVore said.
