NATIONAL STORM SUMMRY

 

NOVEMBER 2013

 

1^st-9^th…Severe storms persisted across the East Coast on Friday as a strong low pressure system moved over the Northeast and pushed a cold front over the Eastern Seaboard. The system pulled abundant moisture and energy in from the Gulf of Mexico and Atlantic Ocean, which allowed for showers and thunderstorms to develop from the Northeast through the Gulf states. Some of these storms turned severe with strong winds and periods of heavy rainfall. Strong winds with gusts from 60 to 70 mph blew down multiple trees and power lines across Pennsylvania and New York state early on Friday. Rainfall totals ranged from 1 to 2 inches as the tail end of the cold front swept through the Southeast.

 

10^th-16^th…Heavy rainfall spread across the Southeast on Friday. A trough of low pressure in the northeastern Gulf of Mexico pushed moisture into the Southeast, which brought scattered showers and thunderstorms to the region. Periods of heavy rainfall spread across northern and central Florida, as well as Mississippi, Alabama, Tennessee, and moved into Georgia. Heaviest rainfall was reported in Meridian, Mississippi with a midday total of 0.99 inches.

A strong low pressure system that brought rain to the West Coast the past few days as moved over the Southwest, pulling more moisture onshore with it. This system has produced rainfall totals over an inch in some areas of the deserts, which has increased flooding concerns for the region. Thus, flood warnings and advisories have been issued from southern California through Arizona. Heaviest precipitation was reported at El Centro, Calif, with a midday total of 1.14 inches of rain.

Texline, Texas saw an inch of snow, while a tenth of an inch of ice was reported at Claredon, Texas. Winter weather advisories and ice advisories remained in effect across the region. Further east, a strong cold front stretched from the Northeast through the Gulf of Mexico, which created heavy rainfall with scattered thunderstorms. heaviest rainfall with this system was reported at El Dorado, Arkansas with a midday total of 2.98 inches of rain.

Alexandria, LA, reported a midday total of 0.99 inches of rain, while De Ridder, LA, reported a midday total of 0.90 inches of rain.
