One of the most unforgettable weather days happened 24 years ago today when a series of deadly and destructive tornadoes hit Connecticut on the afternoon of July 10, 1989. I was the early morning forecaster at the Western Connecticut State University weathercenter in Danbury back then. Although I predicted strong to severe thunderstorms for the region that afternoon, I never imagined the magnitude of the tornadoes which would strike Connecticut later that day.
I remember the storms began early that morning in upstate New York. A tornado hit Ogdensburg just before daybreak, injuring one person. One inch hail and wind gusts of over 50 miles an hour were a telltale sign that the approaching frontal boundary meant business. Many reports of wind damage in New York, Vermont, and Massachusetts occurred before noon.
Unfortunately, the timing of the storm had it moving into western Connecticut by the afternoon hours, when the atmosphere is most volatile due to the heating of the Sun. By midafternoon, as the atmosphere continued to heat up and the front moved eastward, the tornadoes developed. The first tornado, which may actually have been three distinctly separate tornadoes, started in the Northwest community of Cornwall, and leveled the Cathedral Pines forest.
The tornado continued south-southeast through Milton, leveling hundreds of trees and virtually destroying the village of Bantam before dissipating. A 12-year-old girl, who was on a campout with family and friends, was killed by falling trees in Black Rock State Park. Not much later, another tornado touched down in Watertown, passing through Oakville and northern Waterbury . That either damaged or destroyed over 150 homes and injured 70 people.
However, the most destructive tornado occurred in Hamden by late-afternoon. The path was only about five miles long, and it stopped just short of New Haven. The tornado destroyed almost 400 structures, and even cars were tossed into the air. Rows of houses and an industrial park were flattened as a result of the tornado. The storm was so strong that much of the area was without power for at least a week, and there were some trees still being cleared months later. The adjacent photo shows some of the damage in Hamden. This video was made for the Hamden Fire Department's Training Division the day after the tornado struck.
The powerful F-4 tornado which struck Hamden caused $100 million in damage and another $20 million in the Greater New Haven area. Forty people were injured in the tornado. After the tornado dissipated, a wind gust of 80 miles an hour was reported in New Haven. At about that time, another tornado struck Mount Carmel, tearing the roof off a condominium and injuring five people.
Of course, 24 years ago we didn't have the technology we do today, but I was still able to monitor the radar by the time I arrived home early in the afternoon. Remember, the Internet, News 12 Traffic and Weather, and access to instant local weather coverage didn't exist in those days. By the evening, the violent weather had ended, skies were clearing, and the damage had been done. It was certainly a day I'll never forget.

Lawn Care Tips During Hot July Weather
How is your lawn doing? My lawn is beginning to feel the effects of the strong July sunshine and heat wave over the long holiday weekend. Officially, the high temperatures for Friday, Saturday, and Sunday were 92, 92, and 93 degrees, respectively, at Sikorsky Memorial Airport. The hot weather will continue through much of the week ahead. Further, there has been very little rain this month. Less than a quarter-inch of rain (0.24") has fallen at the airport through yesterday. That's below the 0.63" norm through the date.
I've been watering the lawn every day for the last week. However, you may wonder when is the best time to water the lawn? According to allaboutlawns.com, the best time to turn on your sprinkler is about 5 o'clock in the morning. Why? "Early morning watering is best due to the lack of evaporation that takes place, low winds that can blow you lawn dry, high humidity, and morning dew that adds to the moisture.
"Early morning watering helps to prevent lawn diseases that can be caused by watering at night because it gives your lawn time to dry by night fall. Obviously, this can be best accomplished with a sprinkler system, unless you just can't sleep, especially during the Summer months."
Here's another tip. Try watering a day before you plan on mowing your lawn if you dislike the browning that forms on the tips of the grass afterwards. This will allow your lawn to recover from the cutting and help it to look nicer as a result. Did you know that during the hottest Summer months, the surface of your closely cropped lawn can easily climb two dozen degrees above the outdoor air temperature? Heat is a killer.
According to allaboutlawns.com, "It's important to realize that mowing actually creates a routine lawn injury. You can minimize the damage by using sharp blades and mowing in cooler morning or evening hours, but only when the lawn is dry. In the Summer months, you may have to mow more frequently, but always mow at a higher cut. If you're cutting more than 1/3 of the total height of the grass, you're scalping it.
Take care when mowing your lawn this Summer. Properly mowed lawns retain moisture, fostering deeper root growth, and the healthy blades of grass produce more of the nutrients necessary for your lawn to thrive in difficult conditions. So, even in the driest and warmest time of the year, it is possible to keep your lawn watered regularly and cut when needed.

Despite Heat, Earth is Farthest from Sun Today
Despite hot and humid weather this long holiday weekend with temperatures in the upper 80s to lower 90s across southwestern Connecticut, our planet is actually at its farthest point from the Sun today. According to the U. S. Naval Observatory, the Earth reached a point in its orbit called "aphelion" at 11 o'clock EDT this morning. The Earth's aphelion is the point where it is the farthest from the Sun than at any time during the year.
The Earth is typically about 93 million miles from the Sun. However, because our planet's orbit is not a perfect circle but an ellipse, it has a farthest point and a closest point to the Sun. In case you're wondering, the Earth's closest approach to the Sun is called perihelion, and that occurs in early January. The Earth is exactly 3,104,641 miles (or 3.28 percent) farther from the Sun than at its closest approach. The Earth actually receives about seven percent less heat at its aphelion than at its closest approach, according to researchers.
Although the date for both will vary from year to year, the Earth will always be closest to the Sun in early January and the farthest away in early July. Not surprisingly, that comes as a surprise to most people. At perihelion, our planet is about 91 million miles from the Sun. It moves outward to about 95 million miles from the Sun at aphelion. Naturally, some people have the mistaken impression that our seasons are caused by the changes in Earth's distance from the Sun, but this is not the case.
The temperatures and the seasons are not affected by the proximity of the Earth to the Sun or even the rotation of the planet on its axis. Rather, it is the tilt of the Earth that determines the climate. When it is at perihelion in January, the Earth is tilted away from the Sun in the Northern Hemisphere, and the sunlight is not "getting a direct hit" on the Earth's atmosphere. However, when it is at aphelion in July, the Earth is tilted toward the Sun.
Officially, at Sikorsky Memorial Airport in Stratford, the high and low temperatures today were 92 and 74 degrees, respectively, for an average of 83 degrees. That's ten degrees above normal. So, as you cool off at the pool, beach, or by the air conditioner today, take comfort in the fact that our planet is farther from the Sun today than at any other day of the year.

"Dog Days" of Summer Have Arrived
The dog days of Summer run from July 3 through August 11 in the Northern Hemisphere and have to do with the star Sirius, known as “the dog star.” Sirius is the brightest star in the Northern Hemisphere other than the Sun, and it is found in the constellation Canis Major, thus the name “dog star.”
In the Summer, Sirius rises and sets with the Sun. During late July, Sirius is in “conjunction” with the Sun. The ancients believed that its heat added to the heat of the Sun, creating a stretch of hot and sultry weather. They named this period of time, from 20 days before the conjunction to 20 days after, the “dog days” after the dog star.
The Chinese saw different images than the Native Americans, who saw different pictures than the Europeans. These star pictures are now called constellations, and the constellations that are now mapped out in the sky come from our European ancestors.
They saw images of bears (Ursa Major and Ursa Minor), twins (Gemini), a bull (Taurus), and others, including dogs (Canis Major and Canis Minor). The brightest of the stars in Canis Major (the big dog) is Sirius. The star can be seen prominently in the Winter in the Northern Hemisphere, adjacent to Orion the Hunter.
The conjunction of Sirius with the Sun varies somewhat with latitude. Also, the constellations today are not in exactly the same place in the sky as they were in ancient Rome. Although we are in the middle of the dog days of Summer right now, the heat is not due to the added radiation from a far-away star, regardless of its brightness. The heat of Summer is a direct result of the earth’s 23.5 degree tilt on its axis, meaning the Northern Hemisphere is tilted toward the Sun during the Summer.
So, the "Dog Days" of Summer have officially arrived. It will certainly feel hot and humid through the upcoming holiday weekend. In fact, the Independence Day high and low temperatures at Sikorsky Memorial Airport in Stratford were 88 and 74 degrees, respectively, for an 81-degree average. That's seven degrees above normal. The heat index as of 5 o'clock this afternoon was 94 degrees.
Welcome to the "Dog Days."

National Weather Service Confirms Tornado in Greenwich & Stamford
The National Weather Service has confirmed that a tornado moved through Greenwich and Stamford Monday morning, July 1, 2013. The tornado touched down on North Street in Greenwich just North of the Merritt Parkway. It continued East/Northeast into Stamford and lifted on Janes Lane, approximately a half-mile West of Scofieldtown Road.
Extendive tree damage was observed along the tornado's path, starting on Taconic Road and continuing onto Skyridge Road. The worst stree damage was observed just South of the intersection of Stag Lane and Stanwich Road. Tree damage continued onto Carrington Drive and at the Mead House Farm. The tornado began to weaken as it moved into Stamford, just South of Web Hills Road and Lynam Road. There were no injuries, and no visible structural damage was observed during the survey.
According to Dan Warzoha of Greenwich Emergency Management, "The first initial reports were (of a) thunderstorm, possibly (a) microburst. When we got crews to the area, it was evident to us something more forceful had happened."
The estimated time of the tornado was between 10:58 and 11:08 a.m. EDT, and the estimated maximum wind speed was 80 miles per hour. The maximum path width of the tornado was 150 yards, and the path length was 3.7 miles. Governor Dannel Malloy signed an emergency order after the tornado swept through the region.

June Featured Soaking Rains & Above-Average Temperatures
It's official. Last month was the third wettest June on record across southwestern Connecticut. Nearly ten inches (9.48") of rain fell at Sikorsky Memorial Airport in Stratford, which is nearly a half-foot above normal. Hurricane Agnes contributed to nearly a foot-and-a-half of rain in June of 1972, while nearly a foot (11.53") of rain was measured in June of 1982.
Thirteen of the 30 days (43%) last month featured measured rain, including 4.30" on June 7. That happened during a stretch of eight wet days out of 12. The three-day total of 4.60" from June 6 through June 8 was followed by a two-day total of 1.42" on June 10 and 11. During the first 18 days of June, there were just seven completely dry days. The driest stretch of weather happened from June 19 through June 25, when just 0.04" fell on June 24.
Although last month's rain was impressive, it pales in comparison to June of 1972. In fact, more rain fell over a three-day period in June of '72 than all of last month! The monsoon began June 17, 1972, with nearly two-and-a-half inches (2.37″) of rain. The next day, June 18, brought nearly an inch (0.98″). But the deadliest blow happened the next day — June 19 — when over a half-foot (6.18″) of rain buried the region. Cumulatively, 9.53″ of rain fell at Sikorsky Airport.
This June was also warmer-than-normal. The average temperature of 70.0 degrees was 1.3 degrees above the normal average of 68.7 degrees. The hottest temperature last month was 90 degrees on June 25. Twenty of the 30 days (67%) featured an average daily temperature at or above normal. The temperature climbed to 80 degrees or higher 13 days last month. Take a look at this graphic provided by local climatologist Ralph Fato comparing this June to the previous six:
There were 10 days which were cooler-than-normal, including a stretch of three in a row from June 5 through 7 and three in a row from June 18 through June 20. The coolest stretch of weather happened from June 13 through June June 20 when six of the eight days were cooler-than-normal. The coolest temperatutre last month was 53 degrees on June 14. In fact, twelve days saw low temperatures fall into the 50s.
