Weather Summary Friday, October 16, 2009
NATIONAL WEATHER SUMMARY:
In the East, rain and snow were the big story as locations in the Eastern Great Lakes saw some very early snowfall. At Penn State University 0.9 inches of snowfall was measured during the earliest measurable snowfall on record. Just north of campus 4 inches was measured in a grassy area. While the snow falls so early in the
season it will be difficult to accumulate on paved surfaces so
accumulations were confined to trees and elevated surfaces. Rain
was recorded on the order of over one-half an inch from
southeastern Virginia up into southern New Jersey. There have been
reports of snow in northwestern New Jersey and into western
Connecticut. A cold front slowly pushed through the Southeast and
brought rain and strong thunderstorms to the area as the front
approached the Gulf Coast in the evening hours. Widespread rainfall
amounts of 0.50 inches to 1.00 inches occurred in northern FL,
southern GA, and southern AL. A strong thunderstorm in Americus, GA
produced one inch hail as wind gusts knocked over trees and
disabled power to the area.
Across the central portion of the country, some late season severe thunderstorms moved through the Lower Mississippi Valley and parts of the southern Plains. Numerous cities experienced
thunderstorms with gusty winds and downed trees across northern
Louisiana and western Mississippi. These storms brought heavy rain
as well as numerous roads flooded and closed in the Ruston,
Louisiana area as 1-2 inches fell over the region and into southern
Arkansas. The heavy rainfall was fueled by very warm and moist air
which allowed for a record high minimum temperature to be set in
Lake Charles, Louisiana Thursday morning at 79 degrees. Elsewhere, rain and snow showers moved across areas from the Dakotas to the western Great Lakes region. Up to 1.2 inches of snow fell this morning in Clayton, Wisconsin.
In the West, fog was locally dense this morning in central and southern California. Visibilities were less than 500 feet on
Interstate 5 in Buttonwillow, California. The fog lifted over the valleys but persisted near the coast by late morning. Away from those areas light precipitation occurred with light rain and snow showers over the central and northern Rockies and High Plains with drizzle and light rain over the Columbia River Valley in northern Oregon and southern Washington.

In 1987, ten cities in the southeastern U.S. reported record low temperatures for the date. The low of 34 degrees at Augusta GA marked their third straight morning of record cold.
In 1988, late afternoon thunderstorms produced severe weather in southwestern Lower Michigan and northern Indiana. One thunderstorm spawned a tornado north of Nappanee IN which caused half a million dollars damage.
