Migration Weather Forecast

Tuesday Night

Migration traffic is heavy overhead as I type this. Winds are blowing about 15kts at 3500 feet elevation, suggesting that birds will be pushed inland as they land in the morning.

Wednesday Night

South winds will continue on Wednesday night, as the next cold front approaches from the Great Lakes. Precipitation is also expected, and could be heavy at times. This may limit the number of migrants taking flight on Wednesday, but if a substantial number do take off we could see localized concentrations on Thursday morning.

Thursday Night

Winds will turn variable on Thursday night as the low moves north into Canada, and the next one approaches from the southwest. With rain and uncooperative winds in the forecast, expect little in terms of migration.

Friday Night

It all begins again on Friday night, when the next low approaches from the south setting up southerly flow over the mid-Atlantic. There is a chance of precipitation on Friday night, but it's looking minimal at best. Expect a good flight under these conditions.

Birding Forecast

Wednesday Morning

We should see some new birds on the ground Wednesday morning, with the southeast winds favoring inland migrant traps. Belleplain, the Great Swamp, and Garret Mountain should be good choices for Wednesday morning, and make sure to keep an eye to the sky for migrating raptors.

Thursday Morning

The conditions for Thursday will depend on the amount and strength of precipitation on Wednesday night. If birds do take off, the strong southerly winds should disperse them more evenly across the entire mid-Atlantic than on Wednesday morning. If birds take of, but are met with heavy precipitation during flight, these zones of interception will be key places to visit and see what has grounded. Again, with southerly flow continuing throughout the day, keep an eye up for migrating raptors as well.

Friday Morning

No migration is expected between Thursday and Friday, so conditions should remain consistent from Thursday morning.

Saturday Morning

The next push on Friday night should produce new birds on Saturday morning. Right now it looks as if the winds will be out of the southwest which will increase the number of birds across the entire region while favoring coastal migration hotspots.
