Cold Front Blocks Migrants

Tonight we have another cold front moving out of the north that is running head on into migrants moving from the south. It looks like lots of birds will be taking a break in their flight tonight.

Locally the numbers of American Robins has dramatically increased in the last couple of days. Birds that have arrived recently may stay for a while as a high pressure system is moving into the upper midwest and temperatures will be cooler than the last 3 days (actually they will be near normal). By the weekend though winds should be favorable for movement north on the backside of this high pressure system.
