Virginia:
Arlington - From NWS WBC come these notes: " MONTHLY PRECIPITATION FOR SEPTEMBER 2008 WAS ABOVE NORMAL. OVER HALF THE MONTHLY PRECIPITATION OCCURRED ON SEPTEMBER 6TH AS TROPICAL STORM HANNA PRODUCED A NEW DAILY RECORD OF 3.50 INCHES FOR THE DATE. THIS SURPASSED THE OLD DAILY RECORD ON THE 6TH OF 1.55 INCHES SET IN 1996. SEPTEMBER OF 2008 WAS THE ELEVENTH WARMEST DATING BACK TO 1872. THE HIGH OF 95 ON THE 4TH TIED THE OLD RECORD HIGH SET IN 1985. A RECORD HIGH MIN TEMPERATURE WAS SET ON THE 13TH...74...AND ON THE 14TH...AS 75 TIED THE OLD RECORD FOR THE DATE. WARM NIGHTTIME TEMPERATURES CONTINUED FROM THE EVENING OF THE 14TH TO THE MORNING OF THE 15TH WHEN THE OVERNIGHT MIN WAS 80 DEGREES. " [ + + ]
Bridgewater - " The precipitation was 1.2 inches below normal while the temperature was 1.9 degrees above normal. The big rain at the end of the month helped to relieve the dry weather. The rain was in keeping with the trend this past summer with large rains and then a spell of dry weather. The total precipitation for the year is now 26.94 which is about three inches below normal. The weather for the month was rather boring! " - [ + + ] - notes from Clayton
Centreville - Paul sends these notes: "Holy Hanna! Look at all that falln' rain. Just from the remnants of Tropical Storm Hanna, we managed to accumulate 5.37" in 24 hours. Without it, the rain gauge here would have received a little over half of our projected monthly average rainfall of 3.47". The average monthly temperature for September was three degrees over our 66.5° normal breaking a run during the past two months of temperatures at or slightly below the normal average. The high recorded temperature of a pair of 90's on the 3rd and 4th weren't record breakers, but had made an honest attempt at reaching 99° set on the 3rd back in 1980. Our high average temperature of 77.8° came within 1.2° of equaling our typical average of 79°. At the low end of the scale however, the monthly average low of 61.1° recorded here was 7.2° above the 53.9°; the highest deviation for night time temperatures so far this year. In fact, 61.1° was what we would have expected in August for an average low, not September. The minimum temperature for the month reached 48°, a distant 18° from the record low of 30° set back in 1989. With the exception of our 5.37" accumulation from Tropical Storm Hanna, rainfall in sunny Centreville was essentially sparse with 1.55" of the remaining 1.81" falling in the last five days or the month. Thanks to Hanna though, we came out on the plus side for the month by 207% with 3.71" over our normal 3.47". On an annual basis, the end of September placed us at 10.01" above the 32.20" expectation; not far off from where we should be at the end of the year, three months from now. " - [ + + ] -
Chantilly - Russ Topping reports: " Most notable for September were the remnants of Hanna, which moved through the area on the 6th and dumped a record 3.73" at my station. No thunder or high winds, thank goodness, but we did experience flooding in the usual places. The average temperature was 1.5° above normal. We recorded only 3 additional days that barely broke the 90° barrier. Total precipitation for the month was 5.94", which was 2.12" above average. A single thunderstorm rumbled through on the 30th. Dense fog was observed on the 14th and 30th. " - [ + + ]
Dulles - from NWS Sterling (KLWX) come these notes: " THE SEPTEMBER 2008 MONTHLY PRECIPITATION OF 7.18 INCHES MADE IT THE 8TH WETTEST SEPTEMBER ON RECORD. ON THE 6TH A NEW DAILY RECORD WAS SET WHEN TROPICAL STORM HANNA DROPPED 5.11 INCHES OF RAIN BREAKING THE OLD RECORD OF 3.62 INCHES SET IN 1996. THE DAILY RECORD RAINFALL ON THE 6TH MADE IT THE 4TH HIGHEST DAILY RAINFALL TALLIED AT DULLES SINCE RECORD KEEPING BEGAN THERE IN DECEMBER 1962. SEPTEMBER 2008 WAS THE NINTH WARMEST ON RECORD DATING BACK TO 1963. " - [ + + ]
Front Royal - Mike sends these notes for FRV: " Two distinct events defined the month. The first is Tropical Storm Hanna. Precipitation started very late on the 5th and lasted until late afternoon on the 6th. The most intense precipitation fell during the morning hours on the 6th. In Front Royal, VA we received 1.13" of precipitation and winds gusted in the area of 40mph for a brief time early morning of the 6th. While I was hoping for the 7" amounts that fell closer to the DC metro area I was glad no flooding was reported locally. The two highest amounts that I could locate from a NWS statement were 8.35" in Woodbridge, VA and 7.83" in Oakton, VA. The second was the system that developed over 80+ degree water and was warm core, but not a named tropical system. As this system moved onshore and moved up the Appalachian Mountains areas of heavy rain developed along with the occasional clap of thunder. Precip of .20", 2.10", and 2.29", fell on the 25th, 26th and 27th respectively. Flooding was minimal and kept only to the low water bridges in the area and a few side streets. September will be noted for above normal precipitation and temperatures. Even though there was an extended period of dry weather during the mid-month period. It's now October 6th and the leaves are on their way to peak color. Thoughts are now turning to winter and the hope that the 7.4" of last year will be exceeded. " - [ + + ]
Glen Allen - Lowell Koontz reports: " September here when compared to the averages at Richmond Airport was wetter and warmer than average. The total rainfall at the Glen Allen - Springfield Park Weather Center was 5.61 inches and the average at the Richmond Airport was 3.98 inches. The 3.05 inches of rain on the 5th and 6th was the greatest 24 hour rainfall during the month and the greatest in a calendar day was 2.93 inches on the 6th from the remnants of the tropical storm Hanna. The most intense one hour rainfall recorded on September 6th was 0.89 inches. September's mean average temperature here was 71.2°F which was exactly 1.0°F above the September average for the Richmond Airport. The maximum temperature for September was 93°F which occurred on the 3rd and 13th which is hot for September. The minimum temperature during the month was 49°F on the 20th. The maximum wind gust of 28 mph from the NNE occurred on the 6th at 1320 in tropical storm Hanna. Hanna also gave the lowest barometer reading for the month on the 6th when the barometric pressure dropped to 29.44 inches" - [ + + ]
Herndon - Randy reports: " August was near normal for temerature, but well above normal for precipitation. In contrast to the previous couple of months where we were below normal in precipitation, September was over 4 inches above normal due to the extremely heavy rains that came late on the 5th and most of the day on the 6th from the remnants of TS Hannah. I measured a total of 7.37 inches of rain during the two days. A creek a few blocks from my house overflowed its banks for a while on the afternoon of the 6th. It appeared that a band through central Fairfax County received some of the heaviest rainfall totals from this system. I measured a total of 9.26 inches of rain for the month with most the other rain coming during the last six days of the month from a series of showers and thundershowers. For the year, we have now had 41.26 inches which is now about 5.5 inches above normal. As for the temperatures, we had a relatively normal month, with some very warm days and periods of cooler weather. The high temps ending up at just about normal and the lows about 0.6 degrees above normal. " - [ + + ]
Ladysmith - Danny reports: " September's temperatures were very moderate with few extremes, finishing slightly below normal. Thanks to the remnants of Hanna, precipitation was well above normal for the month, despite measurable rainfall occurring on only 5 of 30 days. " - [ - + ]
Mechanicsville - Glenn Martin sends these additional notes: " Tropical Storm Hannah moved through on the 6th with some downpours and small tree branch damage from wind gusts, " - [ M M ]
Portsmouth - " The 5.30" of much needed rain produced a September 2008 that was 0.48" above normal in rainfall or 110% of the norm. September was slightly warmer than normal.

North Carolina:
Greensboro - NWS Raleigh (RAH) reports: " There were numerous widespread rain events throughout September. The heaviest rains this month were associated with the remnants of Tropical Storm Hanna on September 6 and 7, as it moved northward across eastern North Carolina. Figure 1 depicts the radar-estimated rainfall associated with Hanna. Note the widespread 3 to 8 inch storm totals from Laurinburg northward to Roxboro, and the lack of rain in the Mountains. This system was followed by several other large rain events this month. These rains significantly reduced the extent of the drought over all but the far southwest portion of North Carolina during September. The final September rainfall totals generally ranged between 5 and 10 inches across the state. The exceptions were over the southwestern Mountains and near the Albemarle Sound, where only 1 to 3 inches fell. The heavy rain and resultant runoff during September brought relief to the drought-parched region. The September 2008 temperatures averaged slightly above the 30 year normal. Numerous days with clouds and rainfall led to a reduction in daytime highs. This reduction was offset by the warmer and more humid nights due to the cloud cover. For example, Greensboro's average daily high during September 2008 was 79.0 degrees, 0.4 degrees below normal. Greensboro's averaged daily low during the month was 71.0 degrees, 1.2 degrees above normal. The trend of warmer than normal monthly temperatures continued in September over central North Carolina. September 2008 marked the 14th straight month with warmer than normal temperatures at Greensboro. At RDU, 12 of the past 14 months have been warmer than normal. While the majority of the state benefited from heavy rain in late August due to a remnant tropical system, it was the central and eastern areas that received the heaviest rains during September. This allowed the drought conditions to shift out of central N.C. back into the southwest Mountains. Stream flows over western North Carolina set some all time lows during August, but recovered temporarily late in the month. Unfortunately, the reservoir levels remained well below normal. The stream flows remained low and unchanged in September to the west of Asheville, while the northern Mountains saw improvements due to heavier rains in the Yadkin and New River Valleys. To the east, there were reports of minor to moderate flooding throughout the month, even in some of the main stem rivers (including the Neuse, Haw, and Cape Fear rivers). The lake and reservoir levels surged above normal, including at Jordan and Falls Lakes. Figure 11 below depicts the Falls Lake elevation during the past 12 months. Note the spike in the lake level with the heavy rains from Hanna September 6-7, 2008. ...CLIMATE RECORDS FOR THE MONTH OF SEPTEMBER... 14TH...LOW OF 72 TIED THE RECORD WARMEST LOW OF 72 PREVIOUSLY SET IN 2005.

Raleigh - Bob notes: " Rainfall was much above normal due to two storms, TS Hanna and a hybrid storm at the end of the month. Rainfall totaled 9.91" which is 5.65" above normal. It appears drought conditions are finally over. For the third consecutive month, the average daily temperature has been below normal. Made it thru the summer without a 100 degree reading at this station. " - [ - + ]

Tri-Cities - NWS Morristown, TN (MRX) reports: " The monthly-averaged temperature at Tri-Cities was 69.4 degrees, which was 2.8 degrees above normal. It ranked as the 24th warmest September on record at Tri-Cities. The warmest September at Tri-Cities was back in 1970, when the average temperature was 72.9 degrees. Tri-Cities received 2.53 inches of rain in September, which was 0.55 inches below normal. It ranked in the middle one-third of the 71 years of observations taken at Tri-Cities in September. Measurable rain occurred only 10 days, and only one of those days had more than one-quarter of an inch. The heaviest rain fell on the 9th when 1.49 inches was reported, which accounted for over one-half of the total rain for the entire month.
