.DISCUSSION...

High pressure will bring a brief period of fair weather to the
Appalachians and central mid Atlantic region to start the 
workweek. However, low pressure moving through the Great Lakes 
region will push another surge of very cold air into the region 
on Tuesday with blustery conditions and snow showers in the 
mountains. 

Overall, below normal temperatures will keep fire
danger low through the upcoming week.
