One note of caution with this: it is only the surface winds. Birds, as you
know, migrate from a few thousand feet up to probably over 10,000 feet in
some cases and species.

I find this website most helpful for winds aloft forecasts...

https://weather.cod.edu/forecast/  
Pick the model of choice. I usually go with the NAM for the next 3 days and
then the GFS out beyond that (but use with caution).  Pick 925 mb for 1-3
feet above ground level winds, 850 mb for around 5000 feet AGL, 700 mb for
around 1 feet AGL and 500 mb for 2 feet AGL (roughly).  After you
choose the level, pick wind speed. It will give you the wind speed and
direction and you can use the slide bar to project out into the future. You
can easily set jet streaks  (areas of enhanced winds). The site also has
the surface winds too.

Good birding

Best,
Dave

Upon initial review of the forecasts yesterday, the weekend was looking good.
Now, upon review, the forecasts have changed. The warming trend that was
shaping up looks like instead it will be blocked by a northern flow of air
coming down from Canada and the Great Lakes starting Saturday morning. One
forecast model shows the warm air hitting a hard brick wall by Sunday as far
south as a line stretching from around Indianapolis through Columbus and
southeast to Washington DC. That being said, both models show a southern
airflow from Thursday night through Friday morning; albeit chilly, the air will
be from the correct direction to assist migrants attempting to leap-frog their
way north.
I use a combination of weather sites to make inferences (constantly changing…).
Magic Seaweed is one such site. Making sure the time zone is correctly set (top

I found it most interesting to view Temperature element view for the particular
interest of bird migration. The wind always shows as moving white lines. As you
slide the forecast bar across the bottom, you can see how there is a strong
line of demarcation that develops by Saturday morning, the one I described
above. That may hinder migration coming in from the South.
Based upon the current forecast models, it looks like there could be good
fallout conditions along the Lake Erie and Lake Ontario shorelines, or even
here in Ithaca as well. We shall see—forecasts are dynamically changing by the
minute.

[cayugabirds-l] Weather Forecasting Tools

2019-05-14 Thread Christopher T. Tessaglia-Hymes

Upon initial review of the forecasts yesterday, the weekend was looking good.
Now, upon review, the forecasts have changed. The warming trend that was
shaping up looks like instead it will be blocked by a northern flow of air
coming down from Canada and the Great Lakes starting Saturday morning. One
forecast model shows the warm air hitting a hard brick wall by Sunday as far
south as a line stretching from around Indianapolis through Columbus and
southeast to Washington DC. That being said, both models show a southern
airflow from Thursday night through Friday morning; albeit chilly, the air will
be from the correct direction to assist migrants attempting to leap-frog their
way north.

I use a combination of weather sites to make inferences (constantly changing…).

Magic Seaweed is one such site. Making sure the time zone is correctly set (top
left option), I choose my region (bottom left menu) and alternate between wind
and pressure (bottom right options; toggle on/off multiple panes at a time, or
just one pane).

Try this link for Great Lakes region, wind, EDT:

Move your mouse across the bottom from left to right to move through the
forecast dates at the bottom. The closer you are to the current date, the more
accurate the forecast.

Another site is Windy.com.

Lots of custom configuration and tools available, probably the most versatile
site.

The following link has a pin drop positioned approximately over Ithaca with
Temperature selected. Slide the bottom bar across to view the forecast.
Different models can be selected at bottom right (NAM is most accurate and
short-term, ECMWF and GFS are two longer-term models). Top right allows you to
select different element views (wind, temperature, rain, etc.).

https://www.windy.com/-Temperature-temp?temp,38.013,-79.739,6,m:ePOad1V

Based upon the current forecast models, it looks like there could be good
fallout conditions along the Lake Erie and Lake Ontario shorelines, or even
here in Ithaca as well. We shall see—forecasts are dynamically changing by the
minute.

Hope this helps!

Sincerely,
Chris
