Weather synopsis: Sunday April 17

11:31am cold air today rushing in over the unfrozen Great Lakes has produced a light wintry mix of wet snow, sleet and rain downwind of Lake Erie with less than 1" of accumulations expected - meanwhile more tranquil and milder weather can be found along the Atlantic seaboard with temperatures approaching 60 degrees. Winds have been a factor today over the Northeast today gusting over 50 miles per hour. Chilly conditions will linger across the interior Northeast as we head into Monday with another chance of a quick burst of rain and snow over the Great Lakes - conditions along the Atlantic coast should remain mild and tranquil. The next big chance of precipitation will arrive Tuesday into Wednesday. Temperatures should moderate on Wednesday approaching 60 degrees, though it will be mild, there could be enough instability in the atmosphere to produce embedded thunderstorms. Temperature will cool off after Wednesday - this will be especially true over the Great Lakes on Thursday as temperatures fall back into the 40s for day time Highs, it should remain mild though away from the Great Lakes along the Atlantic coast with temperatures in the 60s.

12:54pm a pleasant Friday afternoon is greeting the Northeast today. Temperatures today will run just a degree or two below the average for today's date. A dome of high pressure over the Canadian province of Quebec is responsible for the brilliant sunshine today over the Northeastern US. This will be short lived as the next storm system begins to impact the region late this evening, rain will reach the coast by Saturday. A soaking, heavy rain is anticipated with the onset of this system putting a damper on most Saturday outdoor activities. Behind this system, colder air will rush in over the unfrozen Great Lakes- a light wintry mix of wet snow and sleet could fall Saturday night into Sunday downwind of Lakes Erie. The extended outlook calls for moderating temperatures mid next week along with more rain Tuesday.

Weather synopsis: Wednesday April 6


12:00am after a long, cold and snowy winter the Northeast is finally about to catch a nice break from the big chill beginning this weekend. First we will have to get through the rest of the week. The phrase "April showers" rings true as yet another rain maker looms on the horizon. Partly to mostly cloudy skies are forecast on Wednesday and Thursday along with a scattered shower - high temperatures will range in the 40s on Wednesday and 50s on Thursday. Then a storm system moves into the region on Friday with a threat of more heavy rain, at the moment I think this system will pass just far enough to the south that it should spare us from the brunt of the precipitation. After this storm moves out, a warm air mass will surge into the Northeast. High temperatures on Saturday could approach the 60s and warmer still on Sunday easily breaking 70 degrees, I think that it could end up being even warmer than that, its gonna feel like summer on Sunday. There could be some scattered pop-up thunderstorms on Sunday. Another warm day is forecast for Monday, with more scattered thunderstorms likely across western New York State as the next storm system reaches the western fringes of the Northeast.

Weather synopsis: Saturday April 2


10:07am April is not fooling around, opening up with a Nor'easter that produced heavy rain, snow and strong winds across the region. That storm has departed the Northeast but April is just getting started. We can expect marginally warmer temperatures as well as more heavy rain this month beginning early this week - a storm system charging eastward this up coming week will produce unsettled weather on Monday and Tuesday over the Northeast. There could be enough instability in the atmosphere to produce a squall line of thunderstorms across the region. This storm system will move out quickly, temperatures will range in the 40s ans 50s during the middle of the week with partly to mostly cloudy skies. After this first storm system early next week, the next chance of precipitation will arrive during the later portion of next week, likely in the form of heavy rain and thunderstorms.
