The SPC has increased the threat for severe weather on Saturday.
Discussion:
The stage is set for a potentially damaging severe weather outbreak late in the day on Saturday. A strong cold front, combined with powerful winds aloft, daytime heating and moderate instability, will likely trigger some potent storms.
Forecast:
Isolated showers and thunderstorms could form as early as mid to late afternoon, between about 3 and 6 p.m. However, a line of more widespread thunderstorms and gusty winds is expected to move through between 7 p.m. and midnight.
What to expect:
Strong winds will develop ahead of a cold front, Sustained winds of 15 to 30 mph are expected after 7 p.m. As a line of thunderstorms, possibly severe, moves into Connecticut, winds could gust to between 50 and 70 mph. Hail is not the biggest threat, but any severe thunderstorms could dump some hail. There is also an enhanced threat of isolated tornadoes, mainly across western CT and areas further west.
Impacts:
Use caution with any outdoor plans Saturday evening. Gusty winds can bring down trees and power lines, which may cause power outages, some road closures and in a few cases, storm damage.
