A few area of snow showers continue across the Northeast on Tuesday, while active weather persisted across the Deep South.

In the Northeast, low pressure in southeastern Canada maintained bands of light to moderate snow across the northern and interior Northeast after a cold front over the region departed into the western Atlantic Ocean.

Winds wrapping around the system ushered colder air across the warmer waters of the Lower Great Lakes and triggered lake effect snow showers downwind of Lakes Erie and Ontario.

To the south of this activity, wet and stormy weather continued across the Deep South as the tail of the aforementioned frontal boundary stalled across northern Florida and continued near the central and western Gulf Coasts as a warm front.

A broad swath of southwesterly flow will streaming across the Southern Plains and Southeast allowed moisture to focus along and near these boundaries and translated into another round of rain showers with areas of moderate to heavy rain, possible flooding, and ongoing thunderstorms in the Gulf Coast States.

The southern tier of the central and eastern Gulf Coast States were at slight risk of severe weather development through Tuesday night due to possible damaging wind gusts and tornadoes. Meanwhile, low pressure energy from the SOuthern Rockies moved into Texas and hit the Texas Panhandle and parts of Oklahoma with significant snowfall and parts of the Lower Mississippi Valley with widespread rain.

Snow accumulation in the Texas Panhandle and Oklahoma were expected to range between 6 to 10 inches with locally higher amounts of 12 inches..

ON THIS DATE....... Ice has blocked the Mississippi River at New Orleans only two times in recorded history. The first time occurred on this date in 1784 when ice floes were spotted in the Gulf of Mexico after passing through the river. The second time this occurred was during the Great Arctic Outbreak of 1899.
