Monday looks like the pick day of the extended forecast with seasonable temperatures in the 80s. Early morning clouds and patchy fog will give way to partly cloudy skies later in the day. It will be quite humid, especially in the morning and evening hours. Take advantage of the relatively comfortable day with an intense stretch of heat on the way later in the week.

Partly cloudy
Highs: Around 90

WEDNESDAY:
Sunny and hot
Highs: 95-100
Heat Index: 102-107
Winds: Southwest 5-10 mph
Extreme heat begins to build around much of the eastern 2/3 of the United States. Along with a surge of tropical moisture, temperatures will approach 100 degrees and feel as hot as 102 to 107 degrees with the heat index. It is imperative to check on neighbors, the elderly, and pets and make sure they have access to adequate cooling as temperatures will continue to climb into the low 100s through the Fourth of July holiday weekend. Extreme heat is the leading cause of weather-related deaths in the United States.

Sunny and hot
Highs: 100-105
Heat Index: 107-112
Winds: Southwest 5-10 mph
Intense heat builds across the East Coast with highs well above 100 degrees and heat index values ranging from 107 to as hot as 112 degrees. We will monitor the chance for pop-up thunderstorms, but confidence is low at this time for any relief. The record for Thursday is 101 degrees set over 125 years ago in 1898.

WEDNESDAY INTO FOURTH OF JULY WEEKEND:
Beginning Wednesday and continuing into the Fourth of July holiday weekend, plan for the hottest stretch of weather so far this summer, with afternoon highs well into the upper 90s and may surpass 100 degrees. Overnight temperatures will offer little relief, remaining well into the 70s. to lower 80s The Climate Prediction Center highlights the Mid-Atlantic, including the Washington area, in a ‘moderate risk’ for hazardous heat, signaling increasing confidence that dangerous heat will impact the region. While isolated late-day thunderstorms cannot be completely ruled out, most communities will remain dry, allowing the heat to build day after day. Anyone with outdoor plans leading into the holiday weekend should be prepared for prolonged periods of dangerous heat by staying hydrated, taking frequent breaks in the shade or air conditioning, and checking on vulnerable neighbors, children, and pets. If current trends continue, heat advisories or even extreme heat warnings may become necessary later next week.
