Technical Discussion: Detailed Forecast
A Descriptive Look At Connecticut's Weather Forecast

Happy Friday everyone!The occluded front pushed through very quickly early this morning and as a result we saw the sun much sooner than we had anticipated today! Because of the early arrival of the sunshine we were able to moderate those temperatures quite nicely across the state up into the low and mid 60s! Keep in mind the average high temperature for this date at Windsor Locks is 49 degrees, so we ran a good 10-12 degrees above average. It has also been breezy with our winds coming out of the west to northwest gusting up to 25 mph at times. These winds will diminish as the high pressure moves closer to the area later on Saturday.The upcoming weekend looks gorgeous, with ample amounts of sunshine and seasonable temperatures. During the day on Saturday we will still be under a dry northwest flow keeping our skies fair and temperatures comfortable. Sunday will feature much of the same. We expect clouds to be on the increase towards dark with showers making their way in for the start of the abbreviated work and school week. Winds will also be noticeable possibly gusting up to 25 mph. The combination of wind and cool temperatures will mean very raw conditions, so bring that coat along Monday morning. After all, it is November!The forecast for Monday is a little tricky, the forecast models do not seem to want to agree on their solutions. The NAM brings the chance for very scattered showers but the GFS is indicating much more moisture moving into the area resulting in a steadier rainfall. This would mean a much more significant weather event for the state. For now we will put confidence in the GFS and are forecasting light to moderate rain on Monday. Showers may linger into Tuesday morning but we should see some clearing later in the afternoon. Wednesday will be a partly cloudy day with no rain to worry about which is good news for those of you who will be out traveling the nation's airways and interstates.The outlook for Thanksgiving looks to feature the possibility of the area being affected by a developing coastal low pressure system that will track up the eastern seaboard. As of now it looks like not enough cold air will be in place over the area to support any frozen precipitation, but as we look into Friday that may change. Cold air will work into the area Thursday night thanks to the strong counterclockwise flow around the low pressure system. This could filter enough cold air into the state that we would see some snowflakes flying as the storm tracks into the Canadian Maritimes. This is a system we will continue to watch and update you on as it gets closer.Enjoy the weekend!Weather Intern Tim Pandajis along with Chief Meteorologist Bruce DePrest-------------------------------------------Connecticut's Past Weather By The Numbers Month By MonthOctober 2009
