Heat and high humidity will be held at bay this week and into the Memorial Day weekend over much of the Northeast.
Air conditioners and fans in many areas will sit idle through the week as the weather pattern will suppress summerlike heat and humidity.
During most days this week, temperatures will average near to below normal. Normal highs range from the 60s over much New England and the 70s over the much of mid-Atlantic.
In addition to spring jackets, some may want to keep an umbrella handy with nearly daily occurrences of showers.
The showers will generally be brief, spotty and only pose minor inconveniences to those with outdoor plans most days through Tuesday. The showers will mainly be confined to the midday and afternoon hours. However, showers over Maine will be more numerous and more persistent when compared to the balance of the region.
The warmest part of the week will be midweek.
During the middle of the week, a southerly flow will develop for a brief time. Temperatures will reach the 70s over part of New England and are likely to reach the 80s over the southern part of the mid-Atlantic.
The southerly flow will also bring in more humid air, while a storm system will track in from the Midwest.
It is at midweek when most disruptions to outdoor plans and travel can occur. The combination is likely to trigger pockets of steady rain in New England and locally strong thunderstorms in the mid-Atlantic.
Without a tropical connection, the rainfall is not expected to be excessive and should not greatly affect most area streams and rivers. From 1 to 6 inches of rain fell on portions of the East late last week, which pushed some streams and rivers out of their banks.
Only isolated incidents of flash, urban and small stream flooding are possible.
Fresh, cool air will then quickly sweep away the warm and more humid air, causing the week to end similarly to how it started.
As the system from the Midwest tracks to Atlantic Canada, additional showers will keep the Northeast damp later in the week and into at least the start of the Memorial Day holiday weekend.
The forecast for Memorial Day is uncertain at this time and depends on whether or not the system over Atlantic Canada swings farther to the north and east. For now, the unofficial start to summer is not likely to start on a hot and humid note.
