If the snow holds off and there is sun along Lake Erie, it could be an interesting day for raptor migration too

The added bonus of most hawkwatching sites along the lakeshore is they are also good locations to spot Cave Swallows passing by 👀

Saturday - Flip flop to high pressure again. Cold temperatures and night north winds. Think north side of concentration points such as Lake Erie and Lake Ontario again. Also due to the cold weather swallows may be drawn to concentration points such as sewage lagoons, harbours etc, where insects are

Friday - another drastic change, as another low pressure system moves in, this one moving from the prairies. Cave Swallows could concentrate along western Lake Ontario, particularly Hamilton/Niagara. Rain could be in play on this day, so that could shake things up a bit…

Thursday - Thursday sees a shakeup for weather conditions. High pressure moves in, bring clear skies and cooler temperatures. We may begin to see some CASW moving south, particularly along north facing shorelines (Lake Erie, north shore of Lake Ontario).

Today a fast moving low pressure system with strong southwesterly wind swept through southern Ontario. Not much rain in the way. The winds originated from the southern states and likely gave an addional nudge to any Cave Swallows in the pipeline.

Thousands of newly arrived Long-tailed Ducks were seen in the southern Lake Huron basin yesterday… plus hundreds of other ducks. Waterfowl migration is ramping up!

Wednesday currently looks like a great day for visible migration watches across Ontario! Cool temps and clear skies. Maybe some early Golden Eagles & a Rough-legged Hawk or two👀

As of right now the winds look quite light (under 20kph), so it’s a bit hard to say how things will go. It could be a really good day at Lake Erie hawkwatches, or the flight could shift further inland in the winds gain more of an east/south component during the day
