Heavy
Rainfall from the Remnants of TS Allison
What an event!
A tropical storm forms rapidly in the Gulf, moves inland across S Texas,
and defies "weather sense" by drifting across the Deep South, then NNE
towards SE VA, then on to SE PA and then N to Coastal New England all the
while dumping massive amounts of rainfall over a two-week period.
Instead of weakening and dissipating significantly as is characteristic
after landfall by tropical storms, Allison certainly confounded us all
with unfathomable record rains which translated into considerable flash
flooding across the southern US and East. Many of your monthly rainfall
totals reflect the impact of Allison on our ACON region. Here is
a link to a summary of Allison's assault in the Wakefield forecast area:
Heavy
Rainfall from the Remnants of Allison June 15-16, 2001 (http://www.nws.noaa.gov/er/akq/june01flood.html)
JUNE
2001 Hydrological Report Narrative Summary
http://tgsv5.nws.noaa.gov/er/akq/HYM/JunPre2001.htm
(prepared by
Patrick
Maloit (NWS AKQ):
June was wetter than normal across
most of central...south central & eastern Virginia ...northeast North
Carolina...and the lower Maryland Eastern Shore. This was due to the combined
effects of the remnants of Tropical Storm Allison (mid-June)...coupled
with cold fronts that moved across the Mid Atlantic states in the beginning
& end of the month. June 2001 precipitation totals ranged from 1.52"
at Wallops Island...to 10.91 " at Lewiston in Bertie county.
A cold front pushed across the region
from the west on the 1st to the 2nd...spreading numerous showers and thunderstorms
with it. This rainfall included several 24 hour maxima for the June...including
4.47" at Walkerton (King and Queen County) on the 1st...& 2.87" at
Sandston (Henrico County) from the 1st to the 2nd. Weak high pressure
built in from the 2nd into the 3rd. Then a weak cold front passed through
the region on the 3rd...stalling out across the Carolinas...on the 4th.
An area of low pressure moved along
the front on the 4th...spreading heavy rain across eastern Virginia...including
1.05" at Stoney Creek (Sussex County) from the 4th to the 5th. The front
then lifted north as a warm front on the 5th...and stalled out across the
Eastern Shore by the 6th. The passage of the front brought about 24-hour
rainfall maxima for June at a few locations...with 2.20" at the Elizabeth
city Coast Guard Station on from the 5th to the 6th...and 0.62" at Princess
Anne (Somerset County) on the 6th.
The front then moved south as a cold
front from late on the 6th into the 7th... triggering another batch of
heavy showers and thunderstorms across the region. The maximum 24 hour
rainfall from the 6th to the 7th was 2.18" at Gordonsville (Louisa County)
...its maximum for the month. The front finally stalled out across North
Carolina on the 8th...as high pressure began to build in from the midwest.
This high dominated the weather in the Mid-Atlantic states from the 9th
through the start of the 14th... as it slowly moved from the Mississippi
Valley on the 9th...to off the Mid-Atlantic coast by the 14th.
The remnants of tropical storm allison
began affecting the region late on the 14th ...when the low was near Wilmington
North Carolina...and continued to produce heavy rain across the region
through the morning of the 17th...when the low was off the southeast New
Jersey coast. Some of the 24-hour monthly rainfall maxima caused
by the remnants of Allison were:
4.07" at Lewiston (Bertie County) from the 14th to the 15th...0.86" at
Bremo Bluff (Fluvanna County) on the 15th...2.83" at Alberta (Brunswick
County) from the 15th to the 16th...2.45" at Pungo (Virginia Beach) on
the 16th...4.43" at the Norfolk International Airport from the 16th to
the 17th...and 2.00" at Milford Haven (Mathews county) on the 17th.
High pressure built in from the midwest
on the 17th...to the Appalachians on the 18th...to off the Mid-Atlantic
coast on the 19th where it remained through the 21st. A cold front moved
across the region from the 22nd to the 23rd...finally moving offshore the
morning of the 24th. This slow moving front produced several 24-hour rainfall
maxima for June....including 2.90" at Edenton (Chowan County) from the
22nd to the 23rd...1.74" in the Western Branch portion of Chesapeake on
the 23rd...and 2.50" at north (Mathews county) from the 23rd to the 24th.
Behind the front...high pressure slowly
moved from the Great Lakes on the 24th...to southwest Virginia by the 27th...then
to western North carolina on the 29th. The high kept the region relatively
dry through the period...except for scattered light showers near the coast
and bay on the 28th and 29th. The high moved off the Carolina Coast on
the 30th...allowing a trough of low pressure to develop east of the Appalachians.
This trough produced scattered showers generally west of i-95 on the 30th.

SUMMARY OF
CLIMATOLOGICAL DATA
JUNE
2001
ACON Member Eleanor
Vallier-Talbot returns to MA
Eleanor [CHS]
returns to NWS Taunton, MA [WFO for Boston] in August, the result of another
career move. She writes: "I hope I've been helpful to you with the
ACON during my stay here in SC. I hope that, soon, there will be
a monthly climate summary issued by this office [CHS] again (there has
been talk about it). I'm sure that, if they do, it will appear on
the website so you can get the data again. Take care and keep in
touch." We will surely miss Eleanor's contributions as CHS does not
publish an official monthly summary [only an F-6] and she took the time
for many months to write helpful summaries for data input in these monthly
updates. Her assistance sure did make my data gathering easier!
Eleanor, best wishes for and God speed to you and your husband Dean!

Annandale - Lowell reports:
"June was a good month for plant growth. The mean temp was 1.7°
above normal and the total rainfall was 1.75" above normal. June
was also the clearest June since 1996 although it was the 6th wettest in
the last 21 years. The mean temp for June was the highest since 1996
and the 1.49" rain on the 22nd was the most in a June day since 1998.
The highest wind was 29 mph on the 13th at around 7 PM. The average
temps range was 19.67°, a departure of -0.84°. But the max
daily temp range for the month was only 26° that tied the 21 year record
of 26° in 1989 and 1982. The number of days with max temps of
80° or more was 25. That was the most since 1996 when the record
of 29 occurred. The max temp for the month was 94°. That
was the lowest recorded for June since 1996. The mean barometric
pressure for June was 30.07". The average from June is 29.98" and
the record average is 30.09 inches." [ + + ]
Arlington - NWS WBC reports:
"Mean temps for DCA were 0.4° below normal while rainfall was 1.31"
above normal. Record daily rainfall on the 16th of 1.64 inches
breaking the previous record of 1.34 inches set in 1932. June was
a transition into summer. The first day gave us a cool rainy start
with a high only in the middle 60s. But by the end of the month highs were
in the lower to mid 90s with high humidities. In between were a series
of typical June days. The first week was mainly in the 70s. After that...high
temperatures were generally in the 80s. In the end...the month averaged
out to be near normal for temperatures. Our rainfall total of nearly
five inches was above normal by more than an inch. A number of thunderstorm
outbreaks aided this month in being the second wettest June of the past
ten years. The greatest rainfall was during a thunderstorm on the 16th
which left a record rainfall of over an inch and a half /1.64"/.
The average wind speed was 7.7 mph." [- +]
Blacksburg - Temps were 1.2°
above normal while precip was 0.32" below normal. - NWS Blacksburg [+

Bridgewater - Clayton reports:
"The average monthly temperature was 2.1 degrees above normal. The rainfall
was .65 inches below normal. The precipitation for the year is 3.19 inches
below normal. There were 6 thunderstorms during the month. Three occurred
on the 21st. There were many chances for rain during the month.
Several times, there were three or four days in a row with the chance of
showers or thunderstorms. With all these chances, we got very little rainfall.
The storms seem pass around us. It's getting pretty dry here now." [+
-]
Centreville - Paul writes via
email: "Temperatures for the month of June were interesting in that the
lowest temperature of 50° happened on the first and the highest of
94° on the 30th. Seventy-one degrees is expected as an average
for June and that temperature occurred six days after the start, and six
days before the finish of the month. Overall we were only 0.7°
above what we'd normally expect for this time of year. In the rain
department, well that’s when averages really got a shot in the foot with
172% more than the average of 4.23” for a 7.27” final count. A little
over 52% of the monthly total occurred on June 22nd and 23rd when we received
3.80” in a 24-hour period. After all the water that fell, the clouds
were just about wrung out and were able to come up with only 0.04” for
the remainder of the month. Ha, bet you thought I forgot about the
average daily minimum didn’t you. Well, 2.2° above the 59.2°
expected average low, and that 61° happened just a couple of days past
midmonth; right about where it should be." [+ +]
Charlottesville - Rainfall

New Market - Joyce notes: "Early
morning off the 22nd we had an upper level wind of some kind that took
our roof off the big barn and also a large and very old walnut tree in
the back yard. It rolled the aluminum roof into a big ball and placed
it in the hay field about 100 to 150 feet away from the barn. Crazy
weather."
Norfolk - Jim reports that
60% (4.09") of the monthly rainfall (6.86") was the result from TS Allison.

a new daily precip record of 2.18" was set surpassing the previous record
of 0.55" in 1999. This daily rainfall was a part of the 2.46" to
fall here as a result of the passage of the remnants of Tropical Storm
Allison just a few miles to our west. The month's rainfall made June

high, 81.2 deg. F, and low, 58.8 deg. F, were eight tenths
of a degree lower than the ten year averages, 82.0 & 59.6 respectively,
for the month. It is interesting to note, however, that both the 30 day
heating and cooling degree days, 4 & 153 respectively, were less than
the ten year averages, 17 & 191 DD respectively, for June. The

Concord - Tom reports: "June
finally broke the month after month string of drier than normal months
with a total rainfall of 6.44" or 2.24" above normal. Quite a welcome
sight for an area in midst of an extreme drought. A cut-off low pressure
which moved very slowly westward from the NC Coast provided the above average
