...Closer to Normal Temps...
...Less Rainfall for Most...
...Mountains Pick Up Excess Rains...
A look at the plots for precip and rainfall across our area in May shows a mixed bag.  No real patterns other than obvious above normal rainfall for the mountains of Virginia and North Carolina.  Still any excesses were rather insignificant.  And temps for the most part were above normal in those more mountainous areas while below normal for much of the DC suburbs south through central North Carolina. No obvious temperature patterns for SE VA through central NC; but from Wilmington S along the SC coast, below normal temps noted.  Again, most of those temperature departures from norm were small.   Looks like, all said and told, a rather normal month for temperatures and precipitation across the region.  Rainfall ranged from a meager 0.44" at Danville, Virginia, to a whopping 9.39" at Columbia, South Carolina with 4.47" of that falling on the 11th.  Susan Funk of NWS AKQ notes that the near normal precipitation totals are mostly due to rainfall from showers and thunderstorms. 

Captured these notes of significance from the Web... On the 3rd of May, NWS Wakefield reported damage survey results from May 2nd storms.  The NWS office surveyed damage from Petersburg west to Farmville, VA...and from  Mecklenburg County,  Virginia to Northampton County, North Carolina.  Survey teams found no definitive evidence of tornadoes from either damage path. However, considerable straight-line wind damage...with winds in the 60 mph to 75 mph range was found. Numerous trees were downed...some on homes.  Some roof damage was noted...with the most significant roof damage in the downtown section of Farmville. One mobile home in northwest Nottoway County sustained significant damage. The mobile home damage occurred at the eastern extent of a 3 miles long path of damage that could have been the result of a gustnado.  Gustnados are weak tornado-like features that can spin-up as a result of the strong winds associated with a bow echo/straight-line wind event.  Gustnados are generally weak...with damage in the F0 to F1 range on the Fujita tornado intensity scale. Winds with the Nottoway County System were estimated to be in the 70 to 80 mph range...or a weak F1.

On the 9th of May, flash flooding noted in south-central VA (Martinsville to Danville) in the early morning hours in thunderstorms.  Mudslides reported in Danville area as rainfall of 5 inches recorded in 1.5 hours.

I'm proud to report that NWS people from KPIT were here today installing the thermometer and rain gauge and Davis 3SE, WV is now finally officially up and running.  Pictures of the shelter and rain gauge can be seen with clicks to the instrument above.  It will still be another few weeks before my data will be accepted by the Remote Observation System Automation (ROSA), but when it does, my daily observation will be available on the Internet after 1130 AM each day at http://205.156.54.206/er/pit/PITRVAPIT

Annandale - Lowell reports: "May was average in temperature but a very dry month. The total precipitation for May was 2.31" that was -2.0" below the average. But parts of western Fairfax County had flooding and on the 26th and 27th we only had a few drops here. The 19th through the 23rd was a record cool period. That set five new record low minimum temperatures for the date. This was however offset by the heat near the end of the month. We had seven days of less than or equal to 45F. the most since 1997. The 44 miles per hour wind recorded on the 14th was only 1 mile per hour from the record high wind gust ever recorded in May. The record is 45 miles per hour set in May of 1993. The 1.0" of rain that fell on May 2nd was a 22 year record maximum amount for the date and represented 43% of the rain total for the month of May. May skies were a little clearer than average and the average daily temperature range for the month was the highest since 1999. The 29.44" barometer reading of May 13th was the lowest in May since 1997. By the way, we are 6.77" below average this year and at the end of 2001 we were 7.84" below average for a total deficit of 14.61 inches." [ +/- - ]

Arlington - NWS WBC reports: ...Records... On the 20th...42 set the record low for the day. The previous record was 43 from 1915...Summary... After an exceedingly warm April...May featured a week long cold snap that brought the monthly average down just slightly cooler than normal. As for rainfall... after a good month in April it was back to being drier than normal. However, since most of the rain was in the form of scattered thunderstorms, rainfall did vary widely across the metro area. Dulles Airport to the west had nearly 5 inches on the month, while Washington National Airport had just over 2 inches. The significant weather feature of the month was a much cooler than normal airmass that slid out of Canada. For the period from the 18th to the 23rd, high temperatures were mainly in the lower 60s with lows mainly in the lower 40s. For that six day stretch, temperatures averaged 12 below normal. Although May occasionally has temperatures that low, they are typically associated with cloudy and rainy periods with low pressure off the coast pulling in cool oceanic air. To have those readings with mainly sunny and dry weather is much more uncommon." The average windspeed was 9.4 mph. [ - - ]

Ashburn - Gary reports: "Almost a [ - + ] month! Temperature only 0.5 above normal, and rainfall was .45" above normal, capped by .02" of rain only minutes before the end of the month. Temperature spread was 57.4 F. The rainfall was fairly nicely spaced out through the month, and generally fell at rates beneficial to vegetation and crops. A fair amount of lightning and thunder, with several severe watches and a few warnings, but no thunderstorm reached severe criteria at the station. Winds were generally light; averaging 1.8 mph, with northwest being the dominant direction. The high temperature for the month, 90.3 was warm, but fell short of April's 95.1." [ + + ]

Blacksburg - NWS Blacksburg reports the monthly mean temp was 0.2 above normal while rainfall was 0.67" below normal. [ + + ]

Bridgewater - "There were five consecutive mornings in which there was at least some chance of frost. The 30 on the 22nd did a lot of damage to gardens. In spite of the cold weather, the average temperature for the month was .9 above normal. Although the rainfall was below normal, the rains were beneficial. They were spread out across the month. The total precipitation for the year is now 12.85" which is 2" below normal. There have been 13 thunderstorms so far this year, but none severe in the Bridgewater area." - notes from Clayton [ - - ]

Centreville - "Dick Fletcher of Channel 10 in Tampa, Fl claims that on average in May, they should experience nine days with temperatures of 90 or greater. I'm happy to report that I picked all nine days in a row (and then some) during my recent visit, eliminating any need for further worry about falling short. The folks in the Sunshine State were happy to see me go back to Virginia though because we were delayed slightly in Orlando as a "cold" front passed over bringing their temperatures down to about normal for a while. Looking over what had been happening in Centreville for the past two weeks revealed that May hadn't been setting any temperature records with an average daily high less than 2 above the 71.8 average for the period. The lack of rainfall was reason for concern when just 36% of the 2.21" expected at that point in the month had fallen. The highest high of 91 and the lowest low of 35 kept the mercury active for the last two weeks of May, but still yielded an average daily high just 1.6 above the typical 74.3. Let's hear a big cheer for the nighttime lows because they were only 3.3 above the 48.1 norm. Not bad since the average of average lows for the year has been 8.3 greater than expected. A major rain event of 1.78" on May 26th is noteworthy since it supplied a little more than half of our 3.40" monthly total in just an hour and fifteen minutes. Once the tipping bucket came to rest after doing 2.08" during a 24-hour period, we accumulated 77% of the advertised 4.42" monthly average. Our annual deficit increased by about half an inch over April to 5.79" and our 2002 shortfall is now two thirds of normal." - notes from Paul [ + - ]

Charlottesville - The monthly rainfall total was 3.30" below normal. The average wind speed was 4.9 mph. [ M - ]

Dulles - The mean temp was 0.5 below normal. The monthly rainfall was 0.53" above normal. Average wind speed = 7.3 mph. - from NWS WBC [ - + ]

Falls Church - "May 2002 was slightly above average in temperature and below average in rainfall. There were 7 days with thunderstorm activity but for the most part produced low rainfall amounts. There were no days with an inch or greater." - report from Erica [ + - ]

Harrisonburg - Terry reports: "Temperatures for May averaged -0.4 below normal. Total precipitation for the month was 4.35" which was .77" above normal. Yearly precipitation totals 14.32" which is .41" above normal. For the period December 1, 2001 through May 31, 2002, normal precipitation would have been 16.35". We have received 16.04" for this six month period, leaving a deficit of 0.31 inches." [ - + ]

Herndon Bob notes: " As referenced to Dulles normals--my average max was 2 below and the average min was 1 above normal. The precip was 0.91" above. Can't beat May 1988 for sog - I observed 10.73", a 26-year record for any month. " [ - + ]

Herndon - "A definite change in our previous patterns. The monthly temperature average was NORMAL and rainfall was 1.48 inches ABOVE average. There was a record low temperature of 33.4 recorded on the 22nd, beating the old record of 37 set in 1968. The low temperatures of the 19th and 20th of 38.7 and 38 came close to tying the previous records of 38 and 37. Most of our rainfall came in a deluge on the 26th and the 27th. The total rainfall for those two days was 3.51 inches." - notes from Russ [ +/- + ]

Lynchburg - Rainfall for the month was 0.05" above normal while the mean temp was 0.6 above normal. - from NWS Blacksburg [ + + ]

Newport News - Gary reports: "Much needed rain the first half of the period. 6 record lows for the month with a minimum of 37 on the 22nd. The marks the latest date - by 14 days - for a reading under 40 !! [ M M ]

Portsmouth - The average temp for May was slightly below normal (-0.8), the first month since October 2001 to have a cooler than normal average temp! Unlike in April, the temp never reached 90. Rainfall was 130% of the normal which helped keep temps down. Rain fell mostly in the 1st half of the month with only a trace of rain from the 19th through month's end. A steady flow of station records continued this month: 2nd - Daily precipitation - 1.51" [previously 1.11" 1995]; 9th - Daily precipitation - 1.85" [previously 0.54" 1978]; 10th - Maximum Minimum Temperature - 68 [previously 63 in 1977]; 13th - Maximum Wind Gust - 37 MPH [previously 30 MPH in 1990]; 19th - Minimum Temperature - 50 [previously 51 in 1981]; 19th - Minimum Maximum Temperature TIED - 60 [previously in 1981]; 20th - Minimum Temperature - 46 [previously 50 in 1981]; 21st - Minimum Temperature TIED - 46 [previously in 1981]; 21st - Minimum Maximum Temperature - 61 [previously 62 in 1994]; 23rd - Minimum Temperature - 44 [previously 47 in 1990]; 24th - Minimum Temperature TIED - 51 [previously 1990]. We had only 4 thunderstorm days, but a total of 8 individual TS were noted, an average of 2 per day which is quite high. The average wind speed was 4.0 mph from a dominant southerly direction. For the year, mean temps are running about 3 above normal, down a degree since April, while rainfall was 0.82" above normal (102%). The long-term deficit is nearly 7.0" (since September 2001). The station is located in a large gardens area with many surrounding trees and ponds although the sensor areas are in open circulation. We notice summertime max temps slightly cooler than nearby, more open areas having with plenty of concrete and less vegetation. In the winter, our temps are more similar to other area stations. Quite lucky overall! [ - + ]
