Cape Cod's Winter Weather History

Significant Weather Events
from the NWS Archive

Event:    Heavy Snow
Begin Date:    11 Feb 1994, 1000 EST
End Date:    11 Feb 1994, 2200EST EST
Forecast Zones affected:     Barnstable, Dukes, Eastern Essex, Eastern Norfolk, Eastern Plymouth, Nantucket, Northern Bristol, Northern Worcester, Southeast Middlesex, Southern Bristol, Southern Plymouth, Southern Worcester, Suffolk, Western Essex, Western Middlesex, Western Norfolk, Western Plymouth

Description:
A major nor'easter dumped up to a foot and a half of snow on portions of southeastern Massachusetts. Up to 18 inches of snow was reported around New Bedford and 8 to 15 inches on Cape Cod and the Islands. The remainder of central and eastern Massachusetts received six to nine inches. Strong winds caused considerable blowing and drifting snow, especially over Cape Cod, where this storm was termed the worst since the Blizzard of 1987. Chatham had 13.9 inches and drifts were reported up to four feet deep in Provincetown. The evening commute started during the afternoon in the greater Boston area and soon became a nightmare with long lines of traffic crawling along for many hours. The western portion of the state got off a lot easier with three to six inches of snow. This storm occurred just a couple of days after an earlier heavy snowstorm on February 8-9 and raised total snow depths on the ground to more than 20 inches in urban eastern Massachusetts. There were major headaches for snow removal crews. In the city of Boston, narrow city residential streets were badly clogged with autos and snow, causing a problem regarding public safety. Boston's seasonal snowfall total reached 73 inches, more than the 69 inches recorded in 1977-78 after the "Blizzard of '78." Once again, schools were closed and travel and business disrupted across the state..

WEATHER TRIVIA - VIRGA and DEWPOINT

WEATHER TRIVIA QUESTION: 
What is the dewpoint and why is 65 degrees
so "key" to how it feels.

ANSWER: The dewpoint is the temperature
where the air becomes saturated. In other words
if the temperature were to drop to the dewpoint,
dew, clouds, rain, fog, snow , frost or some
kind of moisture would form. So, the temp. can
never fall below the dewpoint. However, it also
happens to correspond with how much water there
is in the air, so c
oincidentally, our bodies
react to a dewpoint of 65 or more in terms of
"feeling" the humidity. Whether the humidity is
50%, 70%, even 30%, it does NOT matter, we feel
the dewpoint more than the actual relative humidity,
as odd as that sounds.Of course when it is 95
degrees with a dewpoint of 75, we REALLY feel it,
as it makes it feel kind of like 105 (the heat
index, which isn't perfect)... Interesting
stuff!  By the way, anything under 60 is comfortable
and any dewpoint over 70 is just plain muggy or
oppressive.

Last week's Weather Trivia Question is: What is Virga?

ANSWER:
Virga is simply precipitation falling that doesn't ever reach the ground. It shows up on radar very often and makes it "appear" to be raining or snowing on radar when actually it is not.

Weather Trivia - Crazy Temperature Jump Last Week

While we were rainy and relatively cool, one of the world's
craziest, hottest temperature rises happened last week
in Nebraska, but at night! It was a "heat burst"
which is caused by decaying thunderstorms.
The rare setup for a heat burst is dry air directly
beneath a weakening elevated thunderstorm.  When a
thunderstorm is weakening air within the thunderstorm
begins to sink. If this sinking air is very dry it will begin to accelerate
toward the ground since it is more dense. Any remaining
precipitation will fall through this dry air and evaporate.
As the air continues downward, it warms rapidly due to
compression. Needless to say, a heat burst is noted by a
rapid increase in temperature, an extreme drop in relative
humidity and an increase in winds. THE QUESTION: How
much did the temperature rise?

ANSWER: The temperature jumped 23 degrees in 45 minutes between
4:15 am and 5:00 at  Grand Isle, Nebraska to a whopping overnight
temperature of 93 degrees Fahrenheit just before 5am on June 20th,
2006!

WEATHER TRIVIA + FIRST DAY OF SUMMER 6/21/06

The first moment of summer came on  Wednes320pxearthlightingsummersolstice_enday 6/21 at 8:23am. That is the time that the sun shined directly down onto 23.5 degrees north latitude, (the tropic of cancer, just south of Florida) and about to turn the other way, back to the south. (so it appears highest in our sky on the 21st of June as well) It is also the longest day of the year. The diagram on the left shows what is going on. The Earth's axis is tilted 23.5 degrees so as the Earth makes a revolution around the sun, in December the southern hemisphere is receiving the direct sunlight, and in June the northern hemisphere is receiving the direct sunlight. The Equinoxes occur on approximately March 20th and September 21st, when the rays of the sun shine directly down upon the equator.

WEATHER TRIVIA QUESTION: REGARDLESS OF THE ABOVE, WHAT DATE IS THE EARTH CLOSEST TO THE SUN? THE ANSWER IS: AROUND JANUARY 4TH!!! THE EARTH IS ACTUALLY FARTHER FROM THE SUN IN THE SUMMER--->MOST DISTANT ON JULY 4TH.

IN ADDITION TO THE ABOVE, YOU WILL NOTE THAT THE SUNRISE/SUNSET TIMES DO NOT EXACTLY MATCH WHAT YOU WOULD EXPECT FROM THE CALENDAR. (you would think the latest sunset would be June 21st!)  TODD GROSS SUPPORT TEAM MEMBER ERIC WERME HAS WRITTEN AN ARTICLE EXPLAINING WHY.

 

WEATHER TRIVIA QUESTION..

HOW MANY YEARS does it take for a hurricane name to be "repeated" , assuming the name is NOT retired? 

Like Baseball players, hurricane names are retired when they cause enough damage. However, if they are not, they are recycled every six years. The names are picked by the world meteorological organization, whose web page you can find on worldweathernow.com in the sidebar.

June 9, 1953.. Worcester Tornado

While our weather has been bad, it has been matched with a marine flow, a flow of air off the water NOT condusive to severe thunder or tornadoes. On June 9, 1953, however, a cold front that caused tornadoes in Michigan on June 8th, came barreling into the area tornado in hand. Here is a link talking about the storm.

6" of Rain in 24 hours Thursday June 8th

PondsmallIf you look closely at this photograph from Ann Marie of Brewster, you will notice hidden in the woods an extremely small pond, a picture of which was taken Wednesday prior to the rain's onset.

The following picture was taken after 6" of rain fell in less than 24 hours. The pond grew quite a bit!. Click on the images to enlarge!

Meanwhile our Brewster weather spotter, Anne, was keeping us posted during the event frequently, as were all our cape and islands observers. "Doc" rePondbigported winds over 50mph in E. Falmouth as an example. These very localized observations can be accessed if you click on the "Todd's Weather Spotters" link in the sidebar, it is prominently displayed.
