SUMMARY OF CLIMATOLOGICAL DATA
SEPTEMBER 2000


...For the 3rd Consecutive Month, Most of the Area Records
Excess Rainfall and Below Normal Temperatures...

The region noted cooler temps and most all reported above normal rainfall.  Some extreme western areas didn't see the tropical moisture help push rainfall amounts to higher than norm levels as noted to the east.  In fact, the TRI cities area was our only reporting station below normal (and well below) in rainfall.  The really impressive rainfall totals were noted across Southern North Carolina and South Carolina; indeed, North Myrtle Beach and Orangeburg reported double-digit rainfall totals from the passing of the remnants of tropical systems.

In his September narrative hydrologic report for the Wakefield forecast area, Patrick Maloit noted:  SEPTEMBER RAINFALL RANGED FROM NORMAL TO ABOVE NORMAL ACROSS MOST OF THE LOWER MARYLAND EASTERN SHORE...CENTRAL...SOUTH CENTRAL AND
SOUTHEAST VIRGINIA...AND NORTH EAST NORTH CAROLINA. SEPTEMBER MARKED THE FIRST MONTH THIS HURRICANE SEASON THAT THE REGION WAS AFFECTED BY THE REMAINS OF TROPICAL SYSTEMS...WITH THE REMNANTS OF GORDON AND HELENE IMPACTING THE AREA WITHIN 5 DAYS OF EACH OTHER IN THE SECOND HALF OF THE MONTH.  EASTERLY FLOW ACROSS THE REGION...THANKS TO HIGH PRESSURE OFF THE NEW ENGLAND COAST SEPTEMBER 1ST THROUGH 4TH...COUPLED WITH 3 DISTINCT TROUGHS OF LOW PRESSURE MOVING ACROSS THE REGION DURING THAT PERIOD...PROVIDED FOR A WET START TO THE MONTH.   A STRONG COLD FRONT MOVED ACROSS THE REGION FROM THE AFTERNOON OF THE 4TH INTO THE 5TH...RESULTING IN HEAVY RAINFALL ACROSS THE HAMPTON ROADS AREA.   THE COLD FRONT STALLED OFF THE SOUTHEAST COAST ON THE 6TH...AS HIGH PRESSURE BEGAN TO RIDGE IN TO THE MID-ATLANTIC REGION FROM CANADA.   THIS AREA OF HIGH PRESSURE CONTINUED TO DOMINATE THE REGION BEFORE FINALLY MOVING OFFSHORE ON THE 12TH. THIS PERSISTENT HIGH PRESSURE SYSTEM OVER THE NORTHEAST AND MID-ATLANTIC STATES...COUPLED WITH A COLD FRONT THAT PASSED THROUGH THE REGION ON THE 13TH...KEPT HURRICANE FLORENCE WELL OFF THE SOUTHEAST COAST OF THE UNITED STATES. THE FRONTAL PASSAGE ON THE 13TH CAUSED SHOWERS AND THUNDERSTORMS ACROSS THE REGION. THE FRONT STALLED ACROSS NORTH CAROLINA ON THE 14TH...BEFORE FINALLY MERGING WITH A COLD FRONT THAT PASSED THROUGH THE REGION ON THE 15TH.  ANOTHER AREA OF CANADIAN HIGH PRESSURE BUILT INTO THE AREA BEHIND THE FRONT AND DOMINATED LOCAL WEATHER THROUGH THE 18TH...WHEN THE REMNANTS OF TROPICAL CYCLONE GORDON APPROACHED THE REGION.  A WAVE OF LOW PRESSURE FORMED ALONG THE STATIONARY FRONT IN CENTRAL TENNESSEE ON THE 25TH...MOVING OFF THE VIRGINIA CAPES THE MORNING OF THE 26TH. THE EASTERLY FLOW ACROSS THE REGION FROM THIS AREA OF LOW PRESSURE...RESULTED IN MOST OF THE LOCAL 24 HOUR RAINFALL MAXIMA FOR THE MONTH BEING SET FROM THE 25TH INTO THE 26TH. THESE MAXIMA ON THE 25TH AND 26TH OFTEN REPRESENTED BETWEEN ONE-THIRD AND ONE-HALF OF A SITE'S RAINFALL FOR THE MONTH. HIGH PRESSURE BRIEFLY BUILT INTO THE REGION FROM THE TENNESSEE VALLEY ON THE 27TH...BEFORE YET ANOTHER COLD FRONT SPREAD LIGHT PRECIPITATION ACROSS THE REGION ON THE 28TH. BEHIND THE FRONT CANADIAN HIGH PRESSURE BUILT INTO THE REGION TO CLOSE THE MONTH.

The full Regional Monthly Precipitation Summary and Discussions for Virginia can be located on the AKQ homepage at:  http://tgsv5.nws.noaa.gov/er/akq/climate.htm Patrick Maloit continues the hard work on these monthly products.  Please check out the other home pages for the NWS offices for their regional reports.  A great jump-start page for these is: http://www.wrh.noaa.gov/wrhq/nwspage.html  a graphical page for National Weather Service home pages across the nation.

Special note from Paul Bassett

"As time permits I will be putting some notes in better shape that I have used to search for weather related items on eBay.  If you think our ACON members would be interested, they could email me their request at pbassett@sitestar.net  .  I'll be happy to pass them along.

Weather Sites on the Internet

Let's begin a monthly list of weather sites on the Internet which you have found to be good sources for your study of weather or for the advancement of interests in amateur focus on weather.  Whenever you send them, I'll try to get them inserted in the next month's report.  Please make sure you have the exact web URL address, being clear with upper and lower case letters in the address.
