Heat Wave Expands to the East Coast; Flash Flooding Likely in the Central Plains into the Midwest; Severe Thunderstorms in the Northeast

Dangerous, prolonged heat is ongoing in the Mid-South to Mid-Mississippi Valley and heat expands into the Northeast for a brief period today. Widely scattered instances of flash flooding due to heavy rains are forecast from northeast Kansas to much of Indiana. Scattered strong to severe thunderstorms are possible across parts of New England, northern Mid-Atlantic, and North Dakota. Read More >

Overview

A rapidly evolving winter storm impacted the Panhandles on December 2nd, 2020. Communities across the Panhandles saw forecast snowfall amounts increase significantly over a 48 hour period as a rare south/southeastward moving storm system trekked over the forecast area. Rare in the fact these upper level disturbances do not usually take a southward movement through the spine of the Rockies and produce much--if any--precipitation across the combined Panhandles. In fact, the progression of the upper disturbance usually cuts off moisture and we end up dry; however, this was not the case with this system. This storm system was able to pull in a decent amount of Gulf moisture which eventually wrapped around an area of low pressure and dumped heavy snowfall amounts in the far northeast section of the forecast area. Final snowfall amounts ranged anywhere from an inch in the south central Texas Panhandle to around 6 - 12 inches the eastern Oklahoma Panhandle and far northeast Texas Panhandle. In addition to the snowfall, north winds of 20 to 30 mph with gusts exceeding 40 mph at times lead to reduced visibility due to blowing snow. There were periods where conditions got close to that of a blizzard in the northeast combined Panhandles, as visibility dropped to around 1/2 mile with blowing snow (persistent 1/4 mile needed for a true blizzard). Snowfall was still on the ground in the far northeast combined Panhandles three days after the event occurred.
