Bit Unsettled Through the Weekend

Friday’s radar and satellite composite showed plenty of clouds and numerous areas of showers and thunderstorms over the eastern third of the country. The unsettled weather was associated with a large upper level low pressure center spinning eastward through the Ohio Valley.

This weather system will lift north and eastward over the next 24 hours, bringing us a period of unsettled weather for a portion of the upcoming weekend.

Expect clouds to gradually increase Friday and Friday night as moisture over the Mid-Atlantic begins to shift into the region. As we get into Saturday, and the storm system to our southwest approaches, deeper moisture will lift into Southern New England, bringing thickening cloud cover and increasing chances for wet weather.

A surge of warmer and more humid air propelled northward by southwesterly winds aloft will result in numerous showers and some embedded downpours and thunderstorms developing across New England throughout the day on Saturday. While it won’t be raining all day, odds for at least a few hours of wet weather are fairly high and it’s possible some neighborhoods pick up a healthy dose of rain from localized heavier showers.

In addition to the wet weather, Saturday is likely to be rather cool by mid to late June standards.

High pressure built into the region Friday and delivered a brief shot of cool, dry air on east and northeasterly winds. That air mass and its associated onshore wind will remain in place Friday night and Saturday and will cool further when clouds thicken and rain showers develop over the area. As a result, most of the day on Saturday is likely to see temperatures holding in the 60s.

Warmer southwest winds will eventually take control on Saturday night and will propel temperatures and humidity levels upward for the second half of the weekend.
