THEWEATHERMOGIL:: Big chill enroute

Posted byH. Michael Mogil March 19, 2016March 19, 2016

As the risk for a significant New England snow event wanes, attention is now being focused on a major cool-down across the East and the South. In places where temperatures have been running well above seasonal averages for most of March, tumbling temperatures are now in many forecasts. As of late this Saturday afternoon (Mar. 19, 2016), frost and freeze watches, warnings and advisories covered a fairly large region across the Southern Plains into the Tennessee Valley and also across parts of the western Carolinas (Fig. 1). Look for these to be extended eastward and southeastward during the next 12 to 24 hours.

The culprit is an upper level low located over the northern Mississippi River Valley this afternoon (Fig. 2). That low should move into the Ohio River Valley by Sunday, allowing colder air from Canada to infiltrate the eastern half of the U.S. (Fig. 3). Linked to this, a large surface high-pressure system will move into the Southern Plains, allowing a northerly wind flow across a large part of the eastern U.S. (Fig. 4).

Temperatures that were running some 10 to 15 degrees above average for the past week to ten days (and about seven to 10 degrees above average for the month of March) will drop to some seven to 10 degrees below seasonal values by Sunday and Monday. For example, the seasonal average for Birmingham, AL is 56 degrees. Tomorrow (Mar. 20, 2016), the average for the day is only expected to be 46 degrees.
