=== NWS Regional Summary - 430 PM EST MON FEB 19 2007 ===
High pressure building along the coast provided sunny skies today. The
sunshine helped to take some of the edge off the cold, but readings were still
bone chilling in the mid teens to low 20s. Temperatures should cool off in the
early evening. Then clouds will thicken during the night, forming a blanket
that will allow temperatures to actually rise a little overnight. Those clouds
are leading a developing storm in the Great Lakes. The storm will move across
northern New York Tuesday and pass across northern New England Tuesday night.
This will keep quite a few clouds over the region on Tuesday, but with little
in the way of precipitation for us. The storm will eventually swing a cold
front across southern New England Tuesday night. This will bring a chance of
rain and snow showers late Tuesday afternoon into Tuesday night.
