U.S. Weather: Bumpy Travel Week, Potential for Business Disruptions

ImpactWeather StormWatch Domestic Supervisor Mike Venske weighs in on what we can expect from Mother Nature.

The primary threats this week will be centered over the Gulf Coast, Tennessee Valley and Deep South as a slow-moving area of upper-level low pressure interacts with increasing Gulf moisture producing areas of locally heavy rainfall which will likely be measured in inches over many regions, and isolated severe storms which may include hail, frequent lightning, strong, gusty winds and, though unlikely, even isolated tornadoes are possible. This activity will begin in Texas late Tuesday and slowly progress eastward before pushing off the coastal Carolinas by Friday.  Moisture is not expected to surge far enough northward for any type of significant winter weather threat over the Eastern U.S., however light rain showers will be possible as far north as the Ohio River Valley and Mid-Atlantic with the potential for a light wintry mix over coastal New England by the second half of the week.

The PacNW will see another series of Pacific disturbances bringing coastal/lowland rain and mountain snow from Tuesday through Thursday, but nothing close to what was seen in that region last week.  Otherwise, snowfall will be contained to the Sierras and Northern/Central Rockies.

After some light accumulations of snow and freezing drizzle exit the Upper Midwest, Great Lakes and Northeast today, quieter conditions will be seen in these regions as well as the Northern/Central Plains.

Here’s a look at who will be most affected:
