12:30 Update: It almost feels like early fall, doesn't it? Over the last few hours, the "fair weather puffy cumulus" clouds have started to pop up in the sky. These will continue to drift through the horizon. Readings in the state will be in the 70s…I maintained our forecast for upper-70s in Hartford and other northern Connecticut River Valley locations and some of the southwestern Shoreline towns, given current readings and the anticipation of ample sun. If the cumulus fill in a little more of the sky and bring about a little more shade, readings could be slightly cooler – maybe mid-70s in the warmest spots. Higher elevations in northwestern and northeastern Connecticut will be cooler, with low-70s anticipated.
Tonight might not be completely clear and dry. Some models are hinting at patchy clouds and even an isolated sprinkle tonight, mainly before midnight. The "spoke" of energy that I think the model thinks will create this weather is visible on satellite and, although it has no showers with it now, we cannot ignore how the model is interpreting its progress east. So don't be surprised if there is a sprinkle between 8 PM and 2 AM tonight before skies are simply partly cloudy again and lows dip into the 50s by morning.
Good Thursday All!
Yesterday was one for the record books, but not for Connecticut! We're talking about a 24 hour rainfall record for the state of New York! Early yesterday morning, Islip, New York measured 5.41" in just one hour, between 5:00 and 6:00am. That is more than a month's worth of rain in just one hour! Even more incredible is the storm total at Islip. 13.57" of rain fell in less than 24 hours. That is a new 24 hour rainfall record for the state of New York! The previous record was 11.6" at Tannersville, NY during Tropical Storm Irene. For the month of August, Islip is now up to 14.03", which is a new August record and it is only August 14th!
Rainfall in Connecticut yesterday ranged from 1 to 5". Here are some rainfall totals from several of our weather watchers: North Granby 4.60", Higganum 3.51", North Canton 3.45", Hampton 2.80", East Woodstock 2.50", and Wethersfield 2.13". While we did experience some problems with flooding, it was not widespread. We were quite lucky when you consider what happened on the opposite shores of Long Island Sound!
We also dodged a bullet when it comes to severe weather. There were no severe thunderstorms and thankfully no tornadoes. However, southeasterly winds gusted to between 30 and 40 mph and the result was some scattered power outages.
The center of low pressure tracked close to if not directly over Connecticut yesterday afternoon. This system has now moved away to the east of Connecticut and weather conditions have improved. You'll notice cooler and drier air as you step out the door this morning! Low temperatures are in the 50s and lower 60s.
The end of the workweek looks great! Today will feature a blend of clouds and sunshine, a nice breeze, low humidity, and highs in the 70s to near 80 degrees. The mercury will then dip into the 50s tonight with some 40s possible in the normally cooler locations. That'll make for some great sleeping weather! Tomorrow will be a lot like today; dry and comfortable with partly sunny skies and highs between 75 and 80 degrees.
The nice weather will carry over into the first half of the weekend. Saturday should be mostly sunny with morning lows in the 50s and afternoon highs in the lower 80s. The humidity may rise just a bit thanks to a developing southwesterly breeze during the afternoon. By Sunday, a cold front will move into Southern New England. That means scattered showers and thunderstorms are likely. Temperatures should peak in the low to mid 80s before the cold front moves through.
We can expect a return to dry, pleasant weather on Monday and with a little luck the nice weather will last through midweek. However, we will have to watch a low pressure system that will move off the Mid-Atlantic Coast on Tuesday. Some computer guidance models keep the rain far to the south of New England, while other models bring clouds and showers much closer.
Enjoy the rest of your week!
