Warm-up to Begin and End Week Ahead
A cool snap midway through

Jason Samenow @ 1:00 AM

Temperatures will warm up in a big way early in the week before a cold front, accompanied by showers/t'storms, drops them well below average by Thursday and Friday. Seasonable late May weather should return by the weekend.


Nice Day StampPartly to mostly sunny, pleasant. After an unseasonably cold start in the low to mid 40s, temperatures will recover in a hurry. Afternoon high temperatures should reach close to 70 degrees, with low humidity. Overnight, temperatures will fall off but as not far as the night before, with lows 45-50 (suburbs-city).

The Upcoming Week at a Glance

Warmest Day:Tuesday, High 84.
Coldest Day: Thursday, High 66.
Rain Chances: Wednesday afternoon.
Dry Days: Every day but Wednesday.
The Week's Wild Cards: Will the cold front on Wednesday produce any strong thunderstorms. Will a tropical or subtropical system form and affect weather along the East Coast late in the week?
Climatological Average High/Low: 75-77/56-58

Forecast Confidence: HighMostly sunny, very warm. The area of high pressure that brought us the cool, dry air will slide offshore, and a much warmer airmass will move in from the west and southwest. Expect plenty of sunshine with temperatures about 10 degrees warmer than yesterday, with highs 80-85. Overnight, it will be mostly clear and mild, with lows 55-60 (suburbs-city).


Forecast Confidence: Medium-HighIncreasing clouds, afternoon/evening thundershower threat. A strong cold front will move through during the afternoon, likely triggering a round of showers and storms. It will be breezy and somewhat muggy, with highs near 80. Overnight, after some linger showers and storms (especially east), expect gradual clearing with lows in the upper 40s to low 50s.


Forecast Confidence:Medium-HighPartly sunny, cooler. Behind the previous day's cold front, temperatures will drop off a good 10-15 degrees. High temperatures are only likely to reach the mid to upper 60s with a light north to northwesterly breeze. Overnight, it should be mostly clear and cold, with lows 44-48 (suburbs-city).

Forecast Confidence: Medium-HighA mix of clouds and sun, continued cool. Cool northerly flow will persist over the area. As a result, look for another refreshingly cool day, with highs 65-70. (Coastal interests, particularly to the northeast, may need to monitor the development of a tropical or subtropical storm -- low confidence). Overnight, skies should be mostly clear, with lows 45-50 (suburbs-city).

The Weekend

Forecast Confidence: MediumModerating temperatures, dry. High pressure, centered over the area Saturday, will move offshore, allowing temperatures to warm as winds become more southwesterly. Temperatures are most likely to be in the low 70s Saturday, climbing to the mid and upper 70s by Sunday. Overnight lows will be probably be in the vicinity of 50.
