CT Nor'easter: Hour-By-Hour Forecast Of 'Major' Storm
The National Weather Service's estimations of the "major" nor'easter's impacts for Connecticut broken down county by county.

You've already heard or read about it in a dozen different places, you know that a very powerful nor'easter is expected to arrive tonight bringing heavy rain, strong wind gusts, flooding concerns, and some snow on Friday. In an effort to help with your planning for Friday, we're sharing the hour-by-hour forecast for Connecticut.
In examining the National Weather Service's hour-by-hour data, it has become clear that the biggest threats from this storm are flooding and the chance for power outages. For several hours on Friday afternoon and night wind gusts will range between 40 and 55 mph. The wind will be worse on the coast.
Most areas of the state will see 2 inches or more of rain except for Tolland and Hartford counties. And this is not expected to be a big snow event, according to the National Weather Service. The National Weather Service has issued a Winter Weather Advisory for northern Fairfield County for the chance of 2 to 3 inches of snow. A Winter Weather Advisory is in effect for Litchfield County for between 2 and 6 inches of snow, with the most snow falling in the hills. Tolland County could also see a few inches of snow. Everywhere else in Connecticut could see an inch or so of snow Friday.

Flood watches, wind advisories and warnings are also in place for the state. Here is a look at what the state's top meteorologists are predicting from this storm.

Location, location, location!! Upper limit of snow in hills of NW CT is the biggest question! It could be 10", or even OVER 12" if everything worked out just right (or just wrong depending on if you like snow). For many the main focus is rain and wind. pic.twitter.com/gKzsQe1DkT
