Summer Weather Shifts into Northeast

A shift in the wind will have it feeling like summer over much of the Northeast during the midweek.

Although not exactly Julylike, the weather pattern into Wednesday for millions of people in the Northeast will feel just like that as the combination of temperature, humidity, sunshine and other factors send RealFeel temperatures into the 80s.

It has been a slow spring in many areas of the Northeast, but even a large part of New England will catch part of this warm wave at midweek.

Metropolitan areas from Boston to New York City, Philadelphia, Washington, D.C., and Richmond will bask in the warmth Wednesday. This warmth has already been delivered in southern areas.

There's even tropical moisture present off the Atlantic coast of Florida, extending into the eastern part of the Carolinas, part of a failed tropical system from the past weekend.

The exception to the warmth will be much of Maine, northern New Hampshire, the Martimes and the south coast of New England where a flow off of chilly waters will spoil the show.

Much of southern New England will transition from fog and drizzle early Wednesday to hazy sunshine and notable warm and almost humid conditions Wednesday afternoon.

The Same Warm Winds May Bring Summer Storms

The same system producing flooding, severe thunderstorms and tornadoes over the Mississippi Valley will transition eastward Wednesday night into Thursday.

The timing of the system will determine the severity of the storms and the rainfall. It is possible the system will swing through early enough in the day to keep the atmospheric violence to a minimum along much of the Atlantic Seaboard.

Odds are higher for locally damaging storms and flash flooding issues farther west over the Appalachians Wednesday night.

There will be some isolated downpours and thunder ahead of the main system associated with the arrival of the tropical air tonight in the Appalachians and the Delmarva and farther north and east in the mid-Atlantic and New England during Wednesday.

So if you plan on dressing for warm weather, as indeed you should over much of the Northeast Wednesday, don't forget the umbrella. Kids and sports fans could still have their outdoor afternoon and evening activities spoiled by a downpour.

Don't forget, if you can hear thunder, you are at risk for being hit by lighting if you are outdoors.

Warmth Here to Stay?

The weather pattern has certainly snapped like a rubber band in much of the Northeast.

However, cooler, unsettled weather is forecast to return during the first part of May.

Gardeners in the normally chilly areas may want to hold off before planting those tomatoes and other warm-weather plants. At least with the warm break you may be able to get the garden ready now for planting at a later date.

The rest of you may not want to pack away the heavy jacket and long sleeve attire just yet.
