Nor'easter Impacts Change For CT: New Timeline, Storm Details Released

CONNECTICUT — It still looks like a nor'easter storm will impact our weather this weekend in Connecticut but the timeline has changed a bit.

We'll now begin to see the impacts of this strong storm on Friday, especially in the evening hours, as heavy rain and thunderstorms are forecast. Some rain showers may begin on Friday morning.

The rain is forecast to continue on Saturday, but there may be some breaks in the rain too, the weather service said.

Once the low pressure system pulls away, we'll see sunny skies on Sunday but strong wind gusts throughout the day. Wind gusts could approach 35 mph, according to the National Weather Service.

"There will be developing instability...and a few thunderstorms will be possible late (Friday) night and toward Saturday morning, and have maintained the chance for thunder," according to the National Weather Service. "Model guidance suggests that there may be a brief break, or the precipitation becoming light, Saturday morning, and then increase again during the afternoon as the mid and upper level low with the northern stream system tracks across the region and merges over New England. Then Saturday night with the upper trough and low lifting to the northeast the precipitation winds down again."

The weather service said winds are expected to gust between 30-35 mph. Highs on Sunday will be in the middle and upper 50s, but it will feel colder. The winds should diminish Sunday night, the weather service said.

"Steady rain arrives towards the morning commute, with a steady rain Friday and Friday evening. Towards late Friday night into Saturday morning the rain tapers off, with a lingering chance of showers through the day Saturday," the weather service posted in an update Thursday evening.

Accuweather.com meteorologists said a new storm will form and then evolve into a nor'easter as it tracks northward toward New England from Saturday to Sunday.

"From north of New York City to Boston and across much of Maine, the wettest time will occur from Friday to Saturday night. However, the region will be buffeted by gusty winds even as rain diminishes on Sunday," Accuweather.com forecasters added. (Read more at Accuweather.com).

WFSB 3 TV meteorologists Mark Dixon with Jill Gilardi said "showers develop Friday morning, then ramp up in coverage and intensity on Friday afternoon. The coverage backs off some on Friday evening, allowing many to squeeze in football games without getting soaked, then ticks back upwards on Friday night into Saturday morning. The rain looks heavier on Friday rather than Saturday and so we have also declared a First Alert for Friday. Don’t be shocked if you hear thunder too! Rainfall amounts will range from 1-2″ locally. Upper 60s today for highs, and lower to middle 60s tomorrow." (Read more at WFSB 3 TV).
