Pattern Change to Bring Relief From Heat, Humidity to the Northeast and Midwest Later This Week

Hot and humid conditions will grip much of the Northeast through Thursday, but a pattern change will bring relief to end the week. Temperatures have also tumbled several degrees below average in the Midwest.

High temperatures will generally be 5 to 10 degrees above average for mid-August in most of the Northeast through Thursday. That means afternoon readings will be in the 90s in the mid-Atlantic, including Philadelphia and Washington, D.C. Temperatures will also be around 90 degrees in New York City and Boston.

Darker green shadings in this animation indicate higher dew points and, therefore, more humid air. A cold front will bring in cooler and drier air to the Northeast by later this week as shown in white and light green shadings.

Signs of changes to come in the Northeast are already showing up in the Plains and Midwest as a cold front slices south and eastward from Canada.

That front will keep temperatures 5 to 15 degrees below average in much of the northern and central Plains and Midwest late this week. Highs will be in the 70s and lower 80s throughout the region during the second half of the week. A few folks will even remain in the 60s in the northern Great Lakes.

The front will arrive in the Northeast late Thursday into Friday, leaving lower humidity levels in its wake. High temperatures will also drop into the 70s and lower 80s for Friday and the weekend ahead.

Low temperatures will tumble into the 50s in the interior Northeast Friday morning. Lows along the Interstate 95 corridor will fall into the more comfortable 60s by Friday or Saturday morning.
