Monday brings a split forecast for the Cape and Islands. A coastal low offshore will bring steady to heavy rain early tomorrow morning, likely between about 5 and 7 a.m., before it pulls away. A cold front then moves through later in the day, ushering in drier, cooler air. Expect clearing skies by early evening.
Temperatures will be pretty comfortable. After a day that was a touch humid, highs tomorrow should land in the upper 70s to around 80. Overnight will be mostly cloudy, with morning temperatures holding in the upper 60s to near 70. Dew points will rise into the upper 60s to around 70 tomorrow, making it a humid day, but that humidity drops off for the rest of the week.
Beyond Tuesday, high pressure and a dry air mass take over. Dew points will fall into the 40s and 50s, bringing noticeably drier and cooler air. Breezy conditions are expected Tuesday into Wednesday. Wednesday looks to be the coolest day of the next several, with daytime highs mostly in the low to mid-70s. The rest of the week stays dry overall, with cooler-than-average temperatures continuing into the weekend.
Rain chances after Monday are not zero but are limited. Most locations stay dry Tuesday through Thursday, with another weather chance developing Friday as tropical activity remains monitored. The tropics show a tropical storm staying out to sea, posing little or no threat to land. There is also a tropical wave in the southern Atlantic with about a 30 percent chance of development over the next seven days; its potential future track through the Caribbean will be watched.
What to expect:
– Monday: Early morning rain for the Cape and Islands, then clearing; a possible afternoon shower near the front, with no severe weather expected.
– Tuesday to Thursday: Dry, plenty of sun, cooler, and less humid; highs in the 70s.
– Friday into the weekend: Another look at a rain chance, with overall cooler-than-average conditions.
– Tropical outlook: No immediate land threat from the current tropical storm; minor development risk farther south.
A few tips: bring a light rain jacket for early morning commute on Monday, and plan outdoor activities for later in the day after the front passes. Stay tuned for updates, as timing can shift with the coastal low. Overall, the week shifts to comfortable, dry weather after Monday’s early moisture, offering a hopeful, pleasant midweek stretch.
