Weekly Outlook: June 12-18, 2023

Another week, another upper-level low. This week shouldn’t be as gloomy as last week at least.

We’re starting the week off on a mild note ahead of a cold front. Most of the day should remain dry, with plenty of clouds and some sunny break. The shower and thunderstorm activity with the front likely hods off until evening, with most of it coming through overnight tonight into Tuesday morning. We’ll see some clearing in the afternoon, but another shower or thunderstorm may pop up late in the day. The front may stall out across the region before it washes out, with cooler air making into areas north of the Mass Pike, while areas to the south remain mild once again. After that, an upper-level low pressure area settles into the Great Lakes and starts moving eastward. A disturbance rotating around that low will move in on Wednesday, generating showers and thunderstorms. If the timing works out right, some of those storms could be strong to severe during the late afternoon hours, with strong winds, hail, and heavy downpours likely. Thursday will be a bit more tranquil, but with the upper low moving in, we’ll have clouds and possibly some afternoon showers. Right now, Friday and the weekend look fairly similar, with morning sun, afternoon clouds, and possibly a few showers or thunderstorms each day.

Another upper-level low pressure system will influence our weather for much of the week. Loop provided by Tropical Tidbits.
