21 October 2013 Migration Report

Migration is on it’s last legs.  There’s still plenty of movement to be done but it will be more selective than driven.

The high pressure ridge is flattening out and bringing this mild and calm weather.   Winds will be switching to out of the east as temperature and not pressure will be driving them.  A small low pressure cell is organizing out in the Pacific and may bring some southerly winds 48 to 72 hours out.  It’s not a full blown trough so it wont be dragging much arctic air in with it.  We’ll have to see how this plays out.

Here are the radar loops from last night, except Seattle (ATX).  It’s on the fritz.
