Full Worm Moon Happens Today

The Full Moon happens this afternoon at 1:05 EST. This month's Full Moon is known as the Full Worm Moon. However, the March Full Moon has also been called the Crow Moon, Crust Moon, Sap Moon, and Lenten Moon. The nearly Full Moon illuminated last night's clear sky, but we shouldn't see it tonight with a storm system passing to the South.

Full Moon names date back to Native Americans, of what is now the Northern and Eastern United States. The tribes kept track of the seasons by giving distinctive names to each recurring Full Moon. Their names were applied to the entire month in which each occurred. There was some variation in the Moon names, but in general, the same ones were current throughout the Algonquin tribes from New England to Lake Superior.

As the temperature begins to warm and the ground begins to thaw, earthworm casts appear, signaling the return of the robins. The more northern tribes knew this Moon as the Full Crow Moon, when the cawing of crows signaled the end of winter; or the Full Crust Moon, because the snow cover becomes crusted from thawing by day and freezing at night. The Full Sap Moon, marking the time of tapping maple trees, is another variation. To the settlers, it was also known as the Lenten Moon and was considered to be the last full Moon of Winter.

This time of the year, the sunlight is getting stronger, temperatures are slowly rising, and the frozen ground begins to thaw. You can tell the worms have begun to come awake when you find the little curly mounds of dirt on the ground. These mounds, or castings are part of nature's way of preparing the Earth for new growth. Then the flowers and herbs and trees and green grass suddenly burst out and let us know Spring is here.

March Roars Like a Lion

March began where February left off. A snowstorm socked southwestern Connecticut with an average of a half-foot of snow Sunday. Officially, five inches of snow fell at Sikorsky Memorial Airport, tying the record for the date. However, Weston (7.5"), Darien (7"), Stamford (6"), and Fairfield (6") received at least a half-foot of snow. Here is the official report from the National Weather Service.

The five inches at Bridgeport brought the season total to 46.1" which is more than double the normal amount (22.4") through March 1. However, it still paled in comparison to last year's amount of 56.5" through the same date. It was also the 17th day in the last 29 since February 1st with at least a trace of snow at Bridgeport.

Coldest Month on Record Comes to a Close

It was a month for the record books. Not only was last month the coldest February on record, it was also the coldest month ever on record at Sikorsky Memorial Airport. The average daily temperature in February was 19.9 degrees, which broke the previous record for the month of 24.1 degrees set in 1978. In addition, it was also the coldest month on record, breaking the previous mark of 21.9 degrees, established in January of 2004.

So, just how cold was it? Every day last month was colder-than-normal. The temperature dropped into the single digits 14 of the 28 days (50%), with a record low temperature of -2 degrees February 16. Eighteen days featured an average daily temperature at least 10 degrees below normal, and three days were at least 20 degrees colder-than-normal. Fifteen of the last 16 days of February brought average daily temperatures at least 10 degrees below normal.

Nearly two feet of snow (21.5") fell last month, easily topping the average snowfall for the month (8.1). Sixteen days featured at least a trace of snow, with the jackpot of 10.3" on Groundhog Day, February 2. Nearly four inches of snow fell February 21, and there were four straight days with at least a trace of snow from February 7th through the 10th.

However, as far as liquid precipitation is concerned, just over two inches (2.23") fell in February, which is more than a half-inch below normal (2.79"). The greatest 24-hour precipitation total was just about an inch (0.99") from February 1 through February 2. The greatest snow depth was 14" on February 4 & 22. What a month, to be sure!

Beware the Month of March

Today officially marks the last day of meteorological Winter. Unfortunately, that doesn't mean that Winter ends at the stroke of midnight. There is a difference between meteorological Winter and astronomical Winter. Astronomical Winter began on December 21 when the Sun was the farthest from the Earth in the Northern Hemisphere. Meteorological Winter, on the other hand, is simply the period of the year when the Northern Hemisphere is the coldest. That lasts from December 1 through the end of February.

Tomorrow is the first day of March, and although it will feel good to turn the calendar page, the month is anything but serene. March is a transition month as Winter slowly yields to Spring. As for our weather, just about anything goes during the month. The best example of the unpredictable nature of March weather is illustrated on the 13th of the month. That's the date when the mercury reached 84 degrees in 1990, establishing records for the season, month, and date.

Just three years later, though, on the same date, the so-called Storm of the Century dumped over a foot of snow to the region, making it the second snowiest date on record for March at the time. Winds gusted over 40 miles an hour and wind chills were at or below zero. Most of the eastern third of the nation was affected by the massive storm, which stretched from Maine to Florida, including hurricane force winds, tornadoes, strong thunderstorms, and blizzard conditions.

And, five years ago, on March 13, 2010, we experienced an unforgettable Nor'easter which brought flooding rains, damaging winds, massive power outages, and two local fatalities. Peak wind gusts reached 50 to 60 miles an hour in most communities, resulting in downed trees and power lines. Many local roads were impassable, and rainfall rates of up to one-half inch per hour were reported across southwestern Connecticut.

So, what can we expect in March? Basically, anything and everything. Based on local climatology, the normal average daily temperature climbs eight degrees from 36 to 44. The average high temperature increases from 43 degrees at the start of March to 52 degrees by the last day of the month. The record high temperature is 84 degrees set on March 13, 1990, while the record low is four degrees established on March 19, 1967.

As far as precipitation is concerned, the average monthly total is 4.15 inches, making it the wettest month of the year. The wettest March on record occurred in 2010 when several storms brought 10.19" of rain, breaking the previous mark of 9.40" in 1953. The March 13, 2010, storm delivered 3.31" of rain. You may even recall the second wettest March day on record when 3.59 inches of rain fell on March 2, 2007. The average monthly snowfall is 4.3 inches, but there have been some memorable snowstorms. As late as March 22 nearly a foot of snow (11.1") fell in 1967.

The amount of daylight continues to grow during March, but this year we Spring ahead to Daylight Saving Time on Sunday, March 8, so the evening hours will be much brighter than usual. Sunrise on March 1 happens at 6:27, and by the end of the month it will rise at 6:37, due in so small part to the start of DST. Believe it or not, the Sun sets at 5:41 this evening, but by March 31 it will set at 7:17. Personally, it will feel odd to have brighter evenings so early in the year. Not that I mind, of course.

The Vernal Equinox is less than three weeks away. That's the when the direct rays of the Sun are above the Equator, technically marking "equal day and equal night" over the face of the Earth. We'll enjoy about 12 hours of daylight on the first day of Spring, and the amount of daylight will continue to increase through late June.

Cold & Snowy February Continues

The snow is falling this afternoon, and our snowy and extremely cold February continues. In fact, this is the 12th day out of 21 with at least a trace of snow this month at Sikorsky Memorial Airport in Stratford. The total snowfall this month through yesterday is 17.2 inches, which is more than double the normal snow for the entire month (8.1").

This has been an extremely cold month, too. The average daily temperature this month through Friday is just 19.7 degrees, which is an incredible 12.1 degrees below normal. It would take a lot of time to research the last time any month has been that much colder-than-normal across southwestern Connecticut.  The last 26 days have been much colder-than-normal at Sikorsky Memorial Airport in Stratford.

Record low temperatures were set just eight hours apart for February 19 and 20. The temperature dropped to nine degrees Thursday evening at 10 p.m., breaking the previous record of 10 set in 1959. Just eight hours later, the mercury plummeted to one degree early Friday morning, breaking the previous mark of two degrees set in 1966.

Friday's high temperature at Sikorsky Airport was just 20 degrees, which tied the record low maximum temperature for the date which was established in 1966. It was also less than half the normal high temperature for the date (41 degrees), and six degrees below the normal low for the date (20 degrees). It tied the lowest daily high temperature for this month, which happened twice before (February 13 & 16).

The temperature has not climbed above 32 degrees at Sikorsky Airport since Thursday, January 15. However, that streak should be broken tonight or early tomorrow as a southwest wind ushers milder air into the region. Travel is not recommended this evening, though, as the snow and ice will make roads quite slippery. A Winter Weather Advisory remains in effect through 8 o'clock tomorrow morning across all of Connecticut.

Snow will continue this evening before mixing with sleet and freezing rain after midnight. Three-to-six inches of snow are possible before the changeover. An additional one-tenth of ice accretion is likely tonight. Although the high temperature is expected to climb to the upper 30s tomorrow afternoon, it will become frigid once again next week.

Today Marks 12th Anniversary of Presidents Day Blizzard

Today marks the 12th anniversary of the unforgettable Presidents Day Blizzard of 2003. It ranked as the snowiest day on record at the time at Sikorsky Memorial Airport in Stratford, tying the previous mark of 16 inches established on December 19, 1948, over a half-century ago. In New York's Central Park, where records date back well over a century, the 19.8 inches ranked as the fifth snowiest single day total. The weather map below is from midday February 17, 2003.

The snowfall totals across southwestern Connecticut were impressive. Darien and New Canaan measured the most snow (20 inches), while Westport (19"), Bridgeport (17"), Norwalk (16"), and Milford (15") also posted impressive totals. New Fairfield, in Northern Fairfield County, led the way locally with exactly two feet of snow. Here is the satellite image of the massive storm.

The magnitude of the storm was quite impressive. It spread heavy snow across the major cities in the Northeast from Washington to Boston. In fact, it was the biggest snowstorm on record in Baltimore (28.2") and Boston (27.5"). The storm actually developed in the southern Rockies on February 14 and moved through southern Missouri and the lower Tennessee Valley over the next two days. Eventually, the storm brought heavy rain and severe weather to the deep South.

In the Northeast, Arctic air helped slow down the storm and kept all of the precipitation in the form of snow and some sleet. By late Sunday evening, February 16, the snow reached the New York City area, and by midnight, it was snowing across all of southwestern Connecticut. A secondary area of low pressure developed off the Virginia coast the morning of February 17, turning the Nor'easter into a full-blown blizzard.

A storm system is sliding to the South this morning, resulting in slick roads and some travel difficulties. However, it won't be anything like what we experienced 12 years ago today.
