WEST
Review of Last Week
Eagle #16 flew quite a ways between 3/29 and 4/3! (See latest data: Eagle
#16.) On the 29th she was just to the east of the low pressure system which blew into British Columbia on the
30th.

Which way does the wind blow in front of a low? Do you think #16 had a nice tailwind pushing her northward?
This Week
Washington State will have pretty average weather conditions this week. It all starts out on Monday,
April 6th.
As you can see from this map, the area where eagles #12 and #13 still remain is pretty much surrounded by precipitation.
Though no rain is in the forecast, with the rain so close to the area, clouds will definitely be hanging around.
Skies pretty much stay variably cloudy throughout the week. That means no long periods of sunshine.
However, a major storm will pull into the coast on Friday. This storm should bring rain and snow to the entire
northwest. The best chance for our eagles to move might be in the middle of the week from Tuesday the 7th to around
Thursday the 9th, depending on when this large storm moves into the West.
As we move later in the season, the chances that the eagles are going to move anyway, despite the poor weather,
increases. Rather than get a free ride on the thermals they'll have to expend much more energy through flapping
flight. We have already seen movement with varied conditions. Are you surprised?

EAST
Review of Last Week:
The week started out with very warm temperatures, and winds from the south--and look who took another ride between
3/30 and 4/1! (See latest data for Eagle # F42.)
On Wednesday, April 1st some severe thunderstorms moved through. Not very good weather for our eagles to move,
obviously, and evidently F42 stayed put. Things cleared out on Thursday, but the temperatures became much colder.
They returned to the mid to upper fifties, instead of the 70-80 degree weather the eagles had been enjoying.
This Week
As Peter Nye said this week, "What's with that F44 bird?" . Will she EVER move--or is she
a New Yorker after all, and already on her nest? Let's keep an eye on NY's weather one last time this week:
You can see from this map that the weather starts out pretty sunny. After that, things start to go downhill. A
small storm should bring clouds in on Tuesday, April 7th and rain on Wednesday the 8th. After that comes through,
we get hit by another storm on Friday.
It looks like the best chance for F44 to move is on Monday the 6th, but look at the jet stream map. What direction
is the jet stream heading in the East? It is moving southerly right around where F44 is. Does that produce a
head wind, or a tail wind? Just because the sun is out, does that mean that these are good conditions for eagle
migration?
Stay tuned--the next data update will come out on Monday, April 13th.
