...Well-above Normal Temperatures Areawide...
...Drier than normal over North & South Carolina...
...North-central VA sees rains in excess of normal;
rest of Virginia sees below normal precip...
Our members' reports tell it all.  For most, dry, warmer than normal weather.  Several long term records noted throughout the reports.

We even saw an very unusual "mini-heatwave" from about the 14th to the 20th, particularly away from the immediate coastal areas.  

About the only area seeing above normal precip in Aoril 2002 was over north-central Virginia.  

On the 3rd, severe weather developed along a line of thunderstorms running from eastern MD south and southwest to central SC.  Reports of hail and 60 mph wind gusts in eastern NC and eastern SC.  On the 17th, 1.75" hail was reported in late afternoon at Elizabeth City, NC.  On the 19th, a flash flood was reported 4 Sm SE of Blacksburg while reports of wind damage came in from Hopewell and Prince George in Central Virginia.

And then...  The F5 Tornado - La Plata, MD - April 28th


[hook image clearly depicting tornado; from WRC-TV website]

April 28th - Dewey Walston from NWS WBC issued this public information statement. ...Charles County tornado now rated an F-5 on the Fujita scale... ...La Plata tornado becomes the strongest tornado ever recorded in Maryland... a storm survey team from the NWS is currently surveying tornado damage in Charles County. Survey results indicate the tornado was an F-5 on the Fujita scale. Wind speeds in this tornado have been estimated to be greater than 260 mph. This is based on the fact that at least 6 homes were completely wiped off their foundation in Charles County with 3 of these homes just east of La Plata. This is the strongest tornado ever recorded in Maryland. The tornado path length was 24 miles in Charles County and at least 6 miles into Calvert County. The tornado width was 400 yards. The tornado touched town between Risen and Marbury as an F-2 then strengthened to an F-4 as it went through La Plata. The tornado then strengthened to an F-5 on the east side of La Plata. The tornado was at least F-4 strength as it moved to Benedict in Charles County. The tornado then tracked into Calvert County. There are 3 confirmed deaths and over 90 injuries. Images of tornadoes from April 28th appear on our web page at http://www.erh.noaa.gov/er/lwx/publicpix/index.htm

Meanwhile, the Dorchester County, MD, tornado was rated an F-3 on the Fujita scale by the NWS in Wakefield.  One house and several outbuildings were completely  destroyed near Hip Roof Road, about eight miles south of Church Creek.  The tornado path length was estimated to be 16 to 18 miles...on a nearly due east course...and covered almost the entire length of Dorchester County. Most of the 
damage along the path of the tornado was consistent with an F-0 or F-1 tornado.  There were apparently no deaths or injuries as a result of this tornado.

Funnel clouds, hailstorms near Lynchburg, and an apparent tornado in Emporia, Virginia were all a part of a cold front which swept through Virginia, Maryland, & NE North Carolina in the late afternoon and evening of April 28th.

SUMMARY OF CLIMATOLOGICAL DATA
APRIL 2002


Member Profile: Erica Page, Falls Church, Virginia

Erica Page is the latest ACON VA/NC/SC member to be profiled in our monthly reports.  She writes, "I was born and raised in Falls Church, VA and have lived here my whole life.  As a Washington, DC area native I've seen my share of exciting weather.  My interest in weather started at the tender age of 2 when I witnessed the fury of Hurricane Agnes in 1972.  I'll never forget the day after the storm when Dad piled us into the station wagon and we drove around the neighborhood surveying the damage.  I saw a large tree which had crashed through the roof of a nearby house; that image still sticks with me today.  As the years went by my fascination for our atmosphere continued to grow and it became my focus of study in college at George Mason University. I also interned with WRC-TV Meteorologist, Bob Ryan and upon graduation worked there for a number of years.   My dream is to one day go out on a week long storm chase!"  In the picture above, Erica stands in her front yard at the picnic table, one of the sources she uses to calculate snowfall.

Annandale - Lowell reports: "April was warm and near average in precipitation with the uniqueness of a F-5 tornado as close as La Plata, Maryland. April was the warmest since April 1994 and the 3rd warmest in the last 22 years. The mean temperature was 58.8F which was a departure of +3.6F. It will be remembered for its warm week from April 14th-20th that was the warmest week in my 22 years of records for April. Although April 1985 was warm the period lasted for only five days. From Reagan National Airport it would appear to be the warmest April week since April 16-22, 1976. The minimum temperature of 28F on the 7th was the lowest minimum temperature recorded in April since 1997. It was also the clearest April since 1997 with 47% of the month's rain coming in one day (the 28th) . That was the third greatest calendar day rainfall in April in the last 22 years. The lowest daily temperature range for April was only 14F. That was the most ever recorded in 22 years; the old record was +10F and the average minimum daily temperature range for April is 6.4." [ + - ]

Arlington - NWS WBC reports: ...Records... On the 16th...92 set the record high for the day. The previous record was 91 from 1976; on the 17th...95 set the record high for the day. The previous record was 93 from 1976; this 95 reading also tied the highest temperatures ever recorded in April. April was quite a month in Washington. Record high temperatures were broken. We tied the warmest temperature ever recorded in the month. There was a record shattering tornado just south of Washington... Which tore a path through lower southern Maryland and the Eastern Shore of Maryland. Also... we had our first wetter than average month for the first time since the middle of last summer. The month ended up about four degrees above normal...enough to tie it with April 1976 for the eighth warmest April on record. Interestingly enough the two record high temperature records that we broke were both from 1976. The 95 reading on the 17th tied the warmest temperature ever recorded in the month of April. Rainfall was above normal for the first time since July 2001. Helpful for the drought... especially for short term concerns... but reservoirs and ground water remain low and our long term drought rolls on. Particularly helpful was the nearly inch and a half of rain that fell on the 28th. The 28th was a wild weather day for the region. Steady heavy rain in the morning gave way to a few peeks of sunshine and warm muggy conditions. This set the stage for a cold front sweeping southwest through the area. This cold front... tapping the energy from unseasonably warm and humid air... triggered thunderstorms and scattered tornadoes across the Mid-Atlantic states. The strongest tornado tore a path across lower southern Maryland... continued across the bay... and then halfway across the DelMarVa peninsula. That path accounted for a track of roughly 75 miles... and damage that was preliminarily ranked as high as an F5 on the Fujita scale. F5 is the strongest ranking possible and is unprecedented in the area. The average temp for the month was 3.8 above normal while the rainfall totaled 7/10ths inch above normal. The average wind speed was 10.0 mph. [ + + ]

Ashburn - Gary reports: "Something of a month of contrasts. With a low temperature of 23.9 F on the 7th, followed only ten days later by a high temperature of 95.1 F on the 17th, there was certainly some uncharacteristic weather. The spread of 71.2 F between the high and low was one of the more dramatic ones in recent memory. While overall the month finished up 4.4 F above normal, there was plenty of cool weather as well. Interesting to note that while we had 4 days of above 90 F temps, we also had 4 days that reached below the freezing mark. Rainfall ended up on 0.09" below normal, but without the 1.43" on the 28th, another significant deficit month would have gone on the books. For the calendar year, we are 3.77" below normal. Average wind speed for the month was 2.4 mph." [ + - ]

Blacksburg - NWS Blacksburg reports the monthly mean temp was 4.2 above normal while rainfall was 1.17" below normal. [ + - ]

Bridgewater - "Precipitation for the month was 2.49" above normal. Precipitation for the year is now 1.08" below normal. The temperature was 4.2 above normal. An F2 tornado hit the Northern Shenandoah Valley on the 28th causing quite a bit of damage to buildings. Bridgewater wasn't affected. The Shenandoah Valley is now living up to its name as the beautiful Shenandoah Valley with the beneficial rains we have had in the last two months. The grass is very green, and the gardens look great. The rivers, ponds, and streams are full of water. However, we need lots and lots of rain to get the water table up to where it should be. This is the first month in the last seven with precipitation above normal. We have had some very nice beneficial rains during the month. The top soil is in good shape, but we need a lot more rain to raise the water level in the ground." - notes from Clayton [ + + ]

Centreville - "For the most part, April was warm with 95 recorded on the 17th and 18th combined with two other days with temperatures of 90 or above. Those four days helped bring our average daily temperature to 7.1 above our 51.5 normal. A span of seven days with temperatures well above what we typically experience gave our average daily low of 37.2 a boost of 9.5 for the month, even with 25 on April 7th for a record low and three more nights at 32 or below. The 75 cooling degree-days we had worked their way on to the charts during that summer like week as well. The good news has been that our 3.08" of precipitation this month represented 89% of normal, and gave us an almost acceptable finish for the first full month of Spring. The lousy news was that slightly over half an inch of rain fell during the first two weeks accumulating just 17% of our monthly total. It wasn't until the 24 hour period beginning April 28th when the clouds smiled over Centreville and dropped exactly one half of our monthly total with 1.54". It struck me as funny how some were so happy that our deficit was finally being reduced with "all that rain". Throwing more facts on the fire at that point though would have just created more smoke than I'm certain I cared to deal with." - notes from Paul [ + - ]

Charlottesville - The monthly rainfall total was 1.06" above normal. The average wind speed was 5.5 mph. [ + + ]

Dulles - The mean temp was 3.7 above normal. The monthly rainfall was 0.23" above normal. Average wind speed = 8.0 mph. - from NWS WBC [ + + ]

Falls Church - Notes & thought from Erica: "April 2002 will go down as a warmer than average month with my first 90 day on the 16th. I even recorded a 95 day on the 17th ,very unusual for April. The rainfall was average, which is something I haven't seen for quite a few months so it was welcome. I want to extend my prayers and sympathies to the people of the town of La Plata, MD." [ + +/- ]

Harrisonburg - Terry reports: "Temperatures for April averaged 3.5 above normal. Total precipitation for the month was 5.22" which was 2.33" above normal. Yearly precipitation totals 9.97" which is .36" below normal. This is the highest monthly total for precipitation since September 2000. For the period September 1, 2001 through April 30, 2002, normal precipitation would have been 22.93". We only received 13.92" (60% of normal) leaving a deficit of 9.01" for this 8 month period of time." [ + + ]

Herndon Bob reports: "As referenced to Dulles normals, my average max was 2 degrees above and the average min was 6 degrees above normal. Precipitation was 0.75" above normal." [ + + ]

Herndon - "April temperatures continued the warm pattern. They averaged 3.8 above normal. Contributing to this were record highs of 90.5 on the 16th and 92.2 on the 17th. These were the earliest 90 readings ever recorded at my station, and at nearby Dulles International Airport. They did not last long, though. Four days later, on the 21st, the temperature never made it out of the 50's. Thankfully, rainfall was .29 inches above normal in April. Record rainfall of 1.85 inches on the 28th accounted for half of our monthly total. We saw thunderstorms on the 19th, 22nd and 28th." - notes from Russ [ + + ]

Lexington - Scott at WREL reports: "Like many in the Mid-Atlantic, a slow start but busy end to the month of April! Our second consecutive above average month for precipitation. In fact, April was about equal to our January through March total. We recorded 5.13" of rain for the month which was 2.06" above normal. This is welcome news, as our annual deficit has dropped to below two inches of normal. Temperature wise, our average virtually was normal (55.7 vs AVG 55.5 (F)). No official heat wave here as we exceeded 90 only once (4/17). The severe weather outbreak of April 28th spared the Lexington area. While receiving .91" of rain, we experienced no severe weather."

Norfolk - NWS AKQ reported the mean temp at ORF was 5.3 above normal. Rainfall was 0.98" below normal. Rainfall for the year was 1.82" below normal. The average wind speed was 10.7 mph. [ + - ]

Portsmouth - The mean temperature for this April was the 3rd warmest in the database to July 1976. An uncharacteristic April warm spell engulfed the area from the 14th to the 20th with average temps a whopping 17 above normal for the date and an equally whopping number of max temp records tied or broken, 4! April's abundant station records included: 10th - Daily precipitation - 0.27" [previously 0.18" 1998]; 14th - Maximum Minimum Temperature - 62 [previously 61 in 1994]; 15th - Maximum Minimum Temperature - 67 [previously 59 in 1994]; 15th - Maximum Temperature TIED - 83 [previously in 1994]; 16th - Maximum Temperature - 90 [previously 82 in 1998]; 16th - Maximum Minimum Temperature - 66 [previously 63 in 1993]; 17th - Maximum Temperature - 93 [previously 87 in 1992]; 17th - Maximum Minimum Temperature TIED - 68 [previously 1998]; 18th - Maximum Temperature TIED - 87 [previously in 1992]; 18th - Maximum Minimum Temperature - 69 [previously 63 in 1992]; 19th - Maximum Minimum Temperature - 67 [previously 61 in 1995]; 20th - Maximum Minimum Temperature - 66 [previously 64 in 1995].

Weems - Received a nice note from Francis. He writes. "As you may notice, I am a little late sometimes in sending to you the monthly synopsis of the weather from Kilmarnock because of illness. Today is one of those "good" days that I have less pain. At 88, I think I am excused most of the time from daily duties. Since 1925, I keep working on weather problems. I do not use the means that modern weather workers use as I make use of space weather indicators which establish much of Earth's weather is the result of planetary, magnetic impulses, similar to those of most planets. I have rather good results of such notions that planets give to our "elastic atmospheres." I started the study of motions and positions of planets many years ago. I was rebuffed many times and generated much laughter by professionals until recent years when satellites gave information that gave a glimmer of note to the science. Now there is a very good journal in circulation, Space Weather, that gives credence to these beliefs. I love doing what I am doing in weather analysis and forecasting and I have an outlet through a young man in New York that is able to forecast weather with reasonable success a year ahead. He makes good income from such work."

Woodstock - "Quite a weather month!! The wettest in 17 years of records, 3rd warmest, highest April temperature I've ever recorded and one of the highest barometric pressure readings. I've gone several whole summers without recording a temperature as high as 93." - notes from Lauck [ + + ]
