A taste of summer will continue today in the Mid-Atlantic region as temperatures will climb well up into the 80’s in most locations and humidity levels will stay on the high side. Dew points climbed into the middle 60’s on Monday in the Mid-Atlantic region and then they reached the even more stifling upper 60’s on Tuesday to go along with summerlike temperatures. Showers and thunderstorms can break out at just about any time this afternoon and evening although much of the time will be rain-free and any storm that forms can be strong. By tomorrow, a strong cold front will be moving through the Ohio Valley on its way to the east coast and this will enhance the chances for shower and thunderstorm activity in the NYC metro region and there is a decent chance that strong-to-severe storms will develop late tomorrow or tomorrow night in the region between the Carolinas and New England with heavy rainfall, high wind gusts and possible hail.
Once the cold front reaches the east coast by early Friday, it will tend to slow down a bit as a coastal storm develops and this will allow for mostly cloudy skies to continue on Friday along with cooler conditions and the threat for residual showers and this may even linger into Saturday as well. By later in the weekend, strong Canadian high pressure will build into the Mid-Atlantic region and, similar to many previous springtime scenarios, much colder-than-normal air will spread to the eastern states with this high pressure system. As a result, it does not look at all like a “beach-type” weekend for coastal locations in the Mid-Atlantic and Northeast, and frost is actually not out of the question for some interior, higher elevation locations. Cool and dry weather is likely to continue into the latter part of the Memorial Day weekend.
One final note: the tornado that struck Oklahoma on Monday has now been upgraded to an "EF-5" classification level which is the most intense type on the "Enhanced Fugita" scale and it is suggestive of 200+ mph winds.
