Let's take a look back this morning at November weather across the southeast..... courtesy of NOAA.

Mean temperatures in November were variable across the Southeast, with above normal temperatures across much of Florida and below normal temperatures across the remainder of the region. The greatest departures were found across the interior of the region, where monthly temperatures were between 3 and 5 degrees F (1.6 and 2.8 degrees C) below normal, while many coastal locations were between 1 and 2 degrees (0.5 and 1.1 degrees C) below normal. Monthly temperatures were also below normal across Puerto Rico and the U.S. Virgin Islands. In contrast, monthly temperatures across Florida were generally between 1 and 3 degrees (0.5 and 1.6 degrees C) above normal. Miami, FL recorded its fourth warmest November in a record extending back to 1895. Much of the Southeast experienced large swings in temperature throughout the month. After a period of generally seasonable weather, a surge of arctic air overspread the northern half of the region from the 12th to the 14th of the month. Temperature departures of more than 20 degrees F (11 degrees C) below normal were observed, with subfreezing temperatures recorded as far south as the Panhandle of Florida. Temperatures rebounded just days later, with several locations reaching the mid to upper 80s F (low 30s C) as far north as central South Carolina from the 17th to the 18th of the month. Numerous daily high maximum temperature records were set, including Augusta, GA (1873-2013), which reached 86 degrees F (30 degrees C) on the 18th. This marked the warmest maximum temperature observed this late in a calendar year at Augusta. A second surge of arctic air overspread the region less than a week later, with temperature departures of up to 30 degrees F (15 degrees C) below normal. Mount Mitchell, NC (1980-2013) tied a monthly record low temperature of 1 degree F (-17 degrees C) on the morning of the 24th and 25th, while Danville, VA (1945-2013) tied its record low monthly temperature of 15 degrees F (-9 degrees C) on the morning of the 25th. Temperatures remained unseasonably cold through the Thanksgiving holiday, with subfreezing minimum temperatures recorded as far south as Mobile, AL on the morning of the 28th.

November was a dry month across most of the Southeast. Monthly precipitation totals were less than 50 percent of normal along a band stretching from southern Alabama through central Georgia, as well as across central portions of Florida and the Carolinas. In contrast, monthly precipitation was above normal along a band stretching from the Big Bend of Florida through southeastern Georgia, as well as across South Florida and the Keys. Precipitation in November was variable across Puerto Rico and above normal across the U.S. Virgin Islands. Charlotte Amalie Airport on the island of St. Thomas recorded its third wettest November in a record extending back to 1953. A new annual precipitation record was set in Asheville, NC (1869-2013) on the 26th, which stands at 67.55 inches (1716 mm) with one month still remaining. The previous record was 64.91 inches (1649 mm) set back in 1973. Much of the precipitation that fell across the Southeast in November occurred in association with an area of low pressure that tracked across the Florida Peninsula and up the East Coast from the 26th through the 27th of the month. Widespread daily totals of up to 3 inches (76 mm) were recorded with locally heavier amounts of up to 6 inches (152 mm) recorded across parts of northwest Florida and along coastal sections of Georgia and the Carolinas. Many locations also recorded some wintry precipitation from this system, including Atlanta, GA (1878-2013), which recorded only its third measureable November snowfall with 0.4 inches (10 mm) on the 27th. Some ice was also reported on trees, bridges, and elevated surfaces across the western Piedmont of Virginia. The cold outbreak earlier in the month contributed to some light snow across central and eastern portions of the Carolinas on the 12th and 13th. Wilmington, NC (1871-2013) recorded its earliest snowfall observation (trace) of the season on the 13th of the month, one day earlier than the previous record set on November 14, 1976. Monthly snowfall totals of 4 to 6 inches (102 to 152 mm) were recorded along the higher elevations of the Southern Appalachian Mountains.

There were 17 reports of severe weather across the Southeast in November, including three confirmed tornadoes associated with the low pressure system on the 26th of the month. The strongest tornado was an EF-2 that caused damage to a resort, beach club, hospital, and community college in Carteret County, NC. At least two people were treated for injuries. The other two tornadoes, an EF-1 and EF-0, occurred southwest of Tallahassee, FL and resulted in mostly tree damage with some minor damage to outbuildings. Strong storms also contributed to isolated wind damage across parts of Florida and Georgia on the 1st of the month and across northern Virginia on the 17th.

Precipitation deficits across the Southeast over the past three months resulted in an expansion of abnormally-dry (D0) conditions on the U.S. Drought Monitor. By the end of the November, approximately half of the region was in D0, including central and eastern portions of Alabama and Georgia, northeast Florida, and much of the Carolinas and Virginia. While the dry weather helped many farmers complete their harvests (including Christmas trees in western North Carolina), the lack of moisture delayed the planting of several winter crops and limited the growth of pastures, small grains, and some citrus.
