Tuesday cold front (and southwesterly flow)
posted by Paul Lehman | 5:51 AM
The cold front approaching Tuesday morning (6 November) is bringing some rain and--most important--a reasonable southerly and southwesterly flow ahead of the front. This set-up is good for bringing reverse migrants and perhaps a westerly or southerly stray, although it would have been better if the S/SW flow had been of longer duration (and also if the center of the low had tracked northeast from the southern Great Plains and lower Mississippi River Valley, rather than due east and tracking much farther north, eastward across the Great Lakes.
Now that I have sufficiently covered myself via all these caveats (!), the much colder air and northwesterly flow that will follow the passage of the front late today will probably bring a bit of a push of Cave Swallows to Cape May on Wednesday or so, plus some other interesting November goodie just might turn up. There should also be a hawk flight as well as possibly a push of more of the northern irruptives that are starting to appear (e.g., Evening Grosbeaks). We'll see....
