SUMMARY OF
CLIMATOLOGICAL DATA
FEBRUARY 2005
...TEMPERATURES GENERALLY ABOVE NORMAL...
...OVERALL PRECIPITATION BELOW NORMAL WHILE
SNOWFALL TOTALS IMPROVE FOR AREAS ACCUSTOMED TO SNOW...
As your reports suggest, not a lot to talk about in February 2005.
A scan of the data indicates maximum temperatures were about the same as January's but
minimum temperature averages rose above those in the previous month. Overall, temperatures were
above normal while rainfall was below normal. As mentioned earlier, snowfall
totals increased for those of you in snow prone areas. As always, a read of Raleigh's
extensive summary in the link below (narratives) provides a good overview of our
weather.
-
AVERAGE VERSUS MEAN?
-
Albert Arnold of Chesterfield County in Virginia (Winterpock) engaged me in a
lively discussion of the terms "average" and "mean" as they relate to your
monthly calculations. Indeed, statistically they are different.
I have noticed that a couple of you have, in particular, maximum temperature "averages"
considerably higher than surrounding weather sites, official and unofficial.
Two conclusions came out of our email discussions. The first is that a few of you
may actually be computing the "mean maximum temperature", which is indeed not the same as
the "average maximum temperature". The second is that my forms updated last year and based on
those of previous years actually ask for the "mean" maximum, minimum, and monthly temperatures which
is not, as Albert discovered, what our ACON group actually wants to archive. Instead,
we want the "average" maximum, minimum, monthly temperatures AND, most importantly, that's
what most of you have been reporting 'lo these many years (1995 - we're ten years old online in October!)
So, I thank Albert for deducing this problem with our forms and I thank him for being
very observant! Will attach the updated forms for you or can simply interchange the terms mean and
averages on the form where appropriate!

" NO NEW RECORDS WERE SET AT WASHINGTON NATIONAL AIRPORT IN FEBRUARY.
SUMMARY...
FEBRUARY 2004 WAS RATHER TYPICAL. AFTER A DRY START...THERE WERE
SEVERAL WEAK TO MODERATE STORMS THAT AFFECTED THE REGION DURING THE
LATTER HALF OF THE MONTH. ALTHOUGH PRECIPITATION WAS ABOUT AN INCH
BELOW NORMAL...SNOWFALL ENDED UP BEING NEAR NORMAL. TEMPERATURES
WERE SLIGHTLY WARMER THAN NORMAL...MAINLY THANKS TO TWO BRIEF WARM
SPELLS IN EARLY AND MID MONTH.
THERE WERE TWO MODERATE WINTER STORMS ON THE 24TH AND 28TH THAT
PRODUCED NEARLY ALL OF THE SNOW IN FEBRUARY...JUST OVER FIVE INCHES.
ALTHOUGH THERE WERE SEVERAL INCHES OF SNOW WITH THESE...NEGATIVE
EFFECTS WERE LIMITED. TEMPERATURES NEAR FREEZING DURING BOTH EVENTS
MELTED MUCH OF THE SNOW THAT TRIED TO ACCUMULATE ON AREA ROADS.

Bridgewater

The average temperature for the month was 3.36 degrees above normal.
The precipitation was .83 inches below normal. Precipitation for the year
is now 2.81 inches which is 2.06 inches below normal. Snowfall was a little
above normal, thanks to the 5.5 inches which fell on the last day of the
month. This was the biggest snow for this area so far this year.
Places east of here have had more snow than we have had here in the
mountains which is a little unusual. The Eastern Shore of Maryland and
Delaware have had more.
April 15 is my cutoff day for anymore measurable snow. . In my 40
years or so of record-keeping on snow, I haven't had a measurable snow
past this date.

While prognosticator Punxsutawney Phil predicted more winter ahead, perhaps
Phebruary temperatures were excluded from his prophecies when he calculated
those conditions. The monthly mean of 38.3° came in 4.4° above the 33.9°
normal average. The overall warmth was helped along by two days with a high
temperature of 63° which was also our monthly maximum reading. There
were a total of six days when highs were 60° or greater. With one of the 63°
days happening on the 15th, four days later on the 19th was when the
lowest temperature for February was recorded; 16°. Only two other days
gave us temperatures in the teens; the 1st and 2nd with a pair of 17°
mornings. The average monthly minimum of 29.8ø for February came in at a
bone-chilling 0.3° below the previous month and was 5.6° above the 23.3°
average nightly low expected for the month.
Water from melted snow was our principal source of moisture for February
with 1.12" melted from 11.4" of snowfall for the month in three snow events.
Rain accounted for 0.83" yielding a precipitation total for February of
1.95" when combined the water equivalent of snow. While not a remarkable
feat in itself, 0.42" of rain fell on the 15th and produced over 50%
of our unremarkable monthly rain total. A rainfall deficit of 0.98"
this month combines with January for an annual shortage of 1.32"; or 80%
of normal for 2005.

February 2005 was a pretty average month except for snowfall which was an
inch above average for my area.
My biggest snowfall occurred on the 24th, which brought 4 inches.
Strong winds on the 18th brought a number of large branches down in my yard.

February temperatures averaged above normal and precipitation was
below normal. The monthly temperature was 1.9 degrees above normal and

average, with 10.5" total falling on the 3rd (1.0"), 24th (4.5"),
25th (Trace), and 28th (5.0", new record). Freezing rain fell on the
28th, when the snow briefly changed over and then back. This winter
was marked by the extremes in temperatures and the lack of any
significant winter storms (although several were forecast).

"
February was a month of ups and downs, with two distinct warm
periods in the middle of the month interspersed with very cold temperatures.
Winter attempted to make its presence known, with two events at the end of
the month bringing 3.3" of total snowfall. Areas to the north and west of my
Caroline County location received much more snowfall, however. Another month
of below average precipitation puts our 2005 rainfall deficit at 1.8".

Raleigh
- NWS Raleigh (RAH) reports:
Here is an overview from the climate summary from NWS RAH:
"
February 2005 continued the 2004-2005 winter season trends of greatly
fluctuating temperatures along with below normal precipitation. Much like
January 2005, the first half of February averaged warm and dry but the
month would end cold and wet. There was little in the way of storminess,
except for a glancing blow of winter weather on February 3. It would
not be until the final week of February that North Carolina would
receive significant precipitation from two late winter storm systems
that boosted monthly precipitation totals to just less than critical
deficits.
