SUMMARY OF CLIMATOLOGICAL DATA 


SEPTEMBER 2006

... FOR MOST, COOLER AND WETTER WEATHER THIS SEPTEMBER ...

For many in Northeastern North Carolina and Virginia, the remains of Tropical Storm Ernesto brought additional drought relief as it worked its way north on the 1st bringing downpours and localized flooding. (The storm had passed well to the north of Southeastern North Carolina and coastal South Carolina the day before, with storm rainfall totals included in August's report.) Areas not affected by TS Ernesto on the 1st received their significant rainfalls around mid-month as abundant moisture continued to flow north over the region. Rainfall was below normal across South Carolina as well as across southern and southeast coastal North Carolina and above normal most all other areas.

Temperatures in many of our locales averaged below normal. However, a few spots in western and throughout the northern half of Virginia reported above average normals.

  • SNOWFALL MEASUREMENT RESET    It's time to prepare for snowfall measurements! We'll reset the totals for 2006-2007 with the next monthly summary (or when Dave Lesher has his first measurement!). Be sure to reassess your methods for measuring snowfall. You may want to consider a backyard/deck glass table or a snow board rather than measure accumulation on grass/soil surfaces. To avoid inaccurate totals due to melting, try either a board or glass surface above the ground! Also, consider adding a small wattage light bulb in the bottom of your electronic rain gauge. Just a small amount of heat can help keep snow and ice in liquid form during frozen precip events. See Lowell Koontz' paper on Measuring Snowfalls with a click here.


  • SUMMER OF 2006 ONE FOR TEMPERATURE RECORDS    From William Schmitz of the Southeast Regional Climate Center in Columbia, SC come this list of records for heat this summer. View the data here.


  • AUTOMATED SURFACE OBSERVING SYSTEM WIND SENSOR REPLACEMENT    Kevin Shaw of ACON DC/MD/DE, Kevin Shaw, sends this notice on the changes in instrumentation for the ASOS stations across the U.S. View the changes (bottom of file) here.

    Virginia:

    Annandale - Lowell reports: " September was cool and much wetter than average and the cloudiest since 1989. In the last 26 years only five Septembers have been wetter. The 6.92 inches of rain for September was a +2.85 inch departure. The September rainfall was skewed toward the first of the month with 4.63 inches or 68% of the month's rainfall in the first five days. September's average sky cover made it the second cloudiest September in the last 26 years; the cloudiest was 1989. After this wet period, from the 16th to the 27th we had no measurable rainfall for a 12 day period. This year has given our area the most extreme distribution of precipitation I can ever remember. It has been either too wet or too dry for the most part! September's mean average temperature was 65.6F which was a departure of -2.3F. This September was the coolest since 2001 and the fourth coolest September in the last 26 years. But due to the cloudiness the average maximum temperature was the second lowest on record; only 1992 was cooler. September also had the greatest negative temperature departure so far this year. September's average temperature range was only 14.2 the second from the least in the last 26 years due to the cloudiness and humid conditions of this September. The greatest daily temperature range for any September day was only 20F which sets a new 26-year record for the lowest maximum daily temperature range for September. The maximum wind gust of 38 mph from the WNW on the 28th at 1754 during a thunderstorm was the second highest wind ever recorded here in the last 26 years in the month of September. Only September 2003 was greatest due to Isabel. The thunderstorm on the 28th also gave 0.39 inches of rain in five minutes which was the second most intense five minute rainfall ever recorded in September. (Precip. intensity records since 1991) 9 daily records were set - (26-Years of records): 3 LOW maximum temperature: 2, 5, 14; 1 LOW minimum temperature: 21; 3 LOW range temperature: 2, 5, 14; 2 HIGH precipitation: 1, 5. " [ - + ] 

    Bridgewater - " The average temperature for the month was 2.3 degrees below normal. The precipitation was 1.46" above normal. The precipitation for the year is now 31.82 inches which is 2.79 inches above normal. Thunderstorms for the year is now 14 which is below normal. " - [ - + ] - report from Clayton

    Centreville - " Ah yes, September; a perfect month for an Oktoberfest! With the average monthly temperature less than a degree below the 66.5 normal for us in sunny Centreville, and TS Ernesto now just a faint memory, it was a grand time to enjoy. Any bright ideas on how to get about six badminton shuttlecocks off my roof? No prior extremes were exceeded this month; the highest recorded temperature came in at just 82 with a monthly average high of 73.3; 5.7 below our advertised 79.0. At the low end of the temperature scale, September was also fairly well behaved. Our expected average low of 53.9 was exceeded by only 4, coming in at number two for the nearest to normal average low during a month for this year. The average departure for 2006 is running at +5.7. Except for the 3.75" of rain generated by TS Ernesto and a frontal passage on September 1st and 2nd, the precipitation for the month was fairly well distributed. Excluding the accumulation from TS Ernesto, our monthly rainfall amounted to just 0.40" over the 3.47" normal. After all is said and done though, 7.62" was the final tally giving us a 3.76" surplus for the year. Sorry, climbing up on the roof is not an option; next. " - [ - + ] - report from Paul

    Chesterfield - " Albert's backyard creek monthly high level was 6" while its lowest level reached ". " - [ - + ] - report from Albert

    Falls Church - " September 2006 was a cool, wet month and more fall-like rather than late summer. The remnants of TS Ernesto on the 1st brought heavy rain and my peak wind gust for the month at 55 mph. Severe weather on the evening of the 28th brought heavy rain, strong winds (47 mph peak gust) and pea-sized hail. " - [ - + ] - report from Windie

    Herndon - Bob notes: " My average MAX temperature was 6.1 degrees BELOW the Dulles "normal" and the average MIN was 2.0 degrees ABOVE the 1971-2000 "normal". The groundwater observation well at Reston showed a net rise of about one foot during the month, reaching a maximum on the 19th before the 10-day "dry spell." " - [ - + ] 

    Ladysmith - Danny reports: " September 2006 brought the greatest single-month rainfall total in the 11 years I have been taking weather observations across northern and central Virginia, mostly thanks to over 5" in the first 2 days of the month from the remnants of Ernesto. Nearly another 3" fell between the 3rd and 5th of the month, further saturating the region. Year-to-date precipitation is now 8.51" above average. Temperatures moderated from the extreme heat of July and August, with only two days above 90 and a delightful 43 low temperature on the 30th. " - [ - + ]

    Portsmouth - " Tropical Storm Ernesto left a record 6.30 of rain on the 1st with the storm pulling out in mid-afternoon. The month ended in the top 3 wettest Septembers, the THIRD WETTEST SEPTEMBER IN DATABASE TO 1976 AFTER 1) 21.91" IN 1999 AND 2) 10.29" IN 1979. The month cooled off considerably and temps were significantly below normal. No STATION RECORDS FOR SEPTEMBER INCLUDED: 1st RAINFALL 6.30" [previous 1.17" 1997]; 1st WIND 50 mph [previous 37mph 1999]; 2nd TEMPERATURE MINIMUM 61 [previous 63 1987]; 11th TEMPERATURE MINIMUM MAXIMUM 74 [previous 76 1995]; 24th TEMPERATURE MAXIMUM MINIMUM 73 [previous 72 1980]; 24th TEMPERATURE TIED MAXIMUM 88 [previous 1976]; 25th RAINFALL 1.14" [previous 0.87" 1989]; 30th TEMPERATURE MINIMUM 46 [previous 50 1978]. The rains from Ernesto helped to significantly raise the yearly precip totals to near, but still below normal levels. (97% of the norm, or -1.07") " - [ - + ]
