National Composite Reflectivity from around midnight

Regional Overview Last night we had some good conditions for some solid migration, but the high pressure system which I thought had moved out over the Atlantic was still lingering in the Mid-Atlantic. Basically there was a dead-zone of very little movement from North Carolina up through central PA, while all around birds were streaming north everywhere else. We really … Read More

The East finally gets some migration

Drew WeberMigration Update, Predictions1 Comment

Regional Overview It wasn’t extremely heavy migration, but the East Coast did see more widespread migration last night than we have for a while. A combination of clear skies and winds with a south component finally allowed migrants to get up and move. Expect a widespread influx of migrants from Florida to Maine. A cool thing to look at is … Read More

High pressure limits movement in Northeast

Drew WeberMigration Update, PredictionsLeave a Comment

Regional Overview High pressure really slowed down migrants from entering and moving over the Mid-Atlantic and Northeast. The NEXRAD stations in the Mid-Atlantic showed light movement but it really thinned out by the time you get up to New York. Winds will change around and blow from the south over the next several days so we should start to really … Read More

Good run up the coast, fallout potential

Regional Overview The Northeast finally got a good pulse of migrants last night, however the cold front and associated storms limited migration to along the East Coast. New Jersey, extreme eastern PA and NY, and most of the New England states have potential for fallout this morning as storms passed through areas with good migration during the night time hours

Massive storm wipes migration out from west to east

Drew WeberFallout, Migration Update, Predictions1 Comment

Regional Overview A large storm that continues to drift eastward across a continent and the stationary front parked over PA seemed to temper migration some last night. If you check out the Hurtado animation for last night, you can see that migration seemed to flow out of the Mid-Atlantic states up into New York. Overall, migration seemed stronger inland than along … Read More

More birds filtering north

Drew WeberMigration Update, PredictionsLeave a Comment

Regional Overview Last night was a decent night of migration, however a stationary front parked just south of Pennsylvania limited the volume of migrants heading north. You can see in the regional composite map above from around midnight that there was much less detectable migration between the front and the storm. Migration was evident from Florida and the Gulf Coast … Read More

Migration is heating up but mostly to our west

Drew WeberMigration Update, PredictionsLeave a Comment

Regional Overview The high pressure that was over the Ohio Valley has drifted east, keeping migration relatively quiet over the Mid-Atlantic and Northeast last night. Storms to the south prevented much from entering the region but there was a light to moderate movement across Pennsylvania, New York and Ohio. With the storms blocking an influx from the south, we will … Read More

Migration south of the storm

Composite NEXRAD from around midnight

Regional Overview A lot more movement last night, especially south of the storms that spread across NY last night. The strongest migration was across central PA and most of NY where there should be a nice pulse of new species being reported today. There is the possibility of some fallout in central PA where a thin line of storms passed … Read More

Composite NEXRAD from around midnight

Regional Overview Migration was light to moderate across the Northeast as a cold front passed through early in the night. Migration was strongest south of Pennsylvania but there was also movement throughout the night north into New York. My plan for this season is to primarily update the radar on nights/mornings that look good for migration, rather than every single … Read More
