Boston, MA – A cooler-than-normal weather pattern is expected to spread across portions of the Northeast next week, bringing a break from typical late-August temperatures to parts of New England and the Mid-Atlantic.
According to the National Oceanic and Atmospheric Administration’s Climate Prediction Center, below-normal temperatures are favored across a broad section of the Northeast during the six-to-10-day period from Sunday, Aug. 23, through Thursday, Aug. 27.
The strongest signal for cooler conditions stretches from portions of the Great Lakes eastward into New York and parts of New England. The outlook also favors below-normal temperatures extending south into portions of Pennsylvania, New Jersey, Maryland and the broader Mid-Atlantic.
Areas including upstate New York, Pennsylvania and parts of New England appear to have roughly a 40% to 50% probability of below-normal temperatures, based on the outlook map. Other surrounding areas have a weaker but still elevated chance of cooler conditions.
The outlook does not provide exact high and low temperatures. Instead, it shows the probability that average temperatures during the five-day period will finish above, near or below the historical normal for each location.
Precipitation may be less unusual.
NOAA’s corresponding six-to-10-day precipitation outlook places much of the Mid-Atlantic and portions of the Northeast in the near-normal category. Farther north and east, portions of New England have increased chances for above-normal precipitation.
The cooler Northeast stands in sharp contrast to much of the western and southern United States, where above-normal temperatures are favored during the same period.
Travelers and residents should continue checking shorter-range forecasts as Aug. 23 approaches, when specific daily temperatures and rain chances will become clearer.
