After the ups and downs of last week, where high temperatures were as cool as the low 70s and as hot as the upper 90s, the weather will be considerably less changeable this week. Rather than a 30 degree spread in high temperatures, high temperatures should only vary by 10 degrees or so. Conditions will be dry with the possible exception of late Thursday into Friday.
TodayPartly cloudy, not as hot and humid.
It's looking like a pretty typical summer day to start the week. Weak high pressure to the north will deliver slightly cooler and drier air compared to yesterday. Still, high temperatures will be warm, ranging from 83-87, with a touch of humidity. Expect mainly clear skies overnight with lows of 62-67 (suburbs-city).

Will east to northeasterly flow off the ocean Tuesday into Wednesday result in low cloud cover and cooler temperatures than currently forecast? Will the front moving through the second half of Thursday produce any rain and will it linger into Friday? Will the forecast for a fantastic weekend hold up during the week?Climatological Average High/Low:

TuesdayPartly cloudy, a bit cooler.
With high pressure to the north, we should have winds off the ocean which will drop temperatures a bit and result in partly to mostly cloudy conditions. High temperatures should range from 79-83 (depending on the amount of cloud cover, could be slightly higher or lower), about 5 degrees cooler than today. Overnight, skies should be partly cloudy with lows 65-69 (suburbs-city).
WednesdayPartly sunny, warmer?
As high pressure moves offshore, winds should
become more southerly, allowing for temperatures to rise well into the 80s. I only hesitate because we may see a situation similar to last week where the cool, offshore flow hangs in there longer than forecast and rather than seeing highs in the mid to upper 80s, we struggle to reach 80. But, as of now, it looks like after some morning clouds, the sun should break out and with the benefit of those southerly winds, temperatures should reach 84-88. Overnight, look for partly cloudy skies with lows 66-71 (suburbs-city).
ThursdayVery warm. PM storm?
Thursday should be the warmest day this week. Southerly flow ahead of a cold front, will likely boost temperatures to around 90. The front could trigger some showers and thunderstorms in the afternoon and evening hours (25% chance). Overnight, it should be mostly cloudy, with a 20% chance of showers or storms and lows 66-71.
FridayAM showers, not as warm.
There may be a few lingering showers (20% chance) as a cold front slowly moves off to our east, especially during the first half the day. Otherwise, expect partly cloudy skies and high temperatures 82-86. Mostly clear skies and comfortable conditions overnight, with lows 59-64 (suburbs-city).
Labor Day WeekendExcellent potential Saturday into Sunday, Monday uncertain.
Cool high pressure is likely to build in from the northwest Saturday bringing very refreshing air to the region under partly sunny skies. Highs should generally range from 79-84, with overnight lows between 58-65 (suburbs-city). Sunday and more likely Monday, there is a chance the flow will become easterly -- increasing cloud cover and dropping temperatures -- especially towards the Eastern Shore. Not a certainty, but something to watch.
