9/13 IL Migration Report

Hey all!

So tonight we see the continuation of last night's northerly flow, though the migration is not nearly as heavy. The reasons for this are not entirely clear, but looking at the surface analysis, incoming high pressure may be part of it ( By tomorrow afternoon, winds will have shifted away from their northerly inclination and toward quite the opposite, by then coming from the south as the high pressure rushes through the east ( This high pressure is forecast to leave us with southerly winds at least through Sunday, so tonight's light to moderate migration ( may be as heavy as it gets for a couple days. At least we got one night of madness!

Birding will still likely be very good tomorrow because of the heavy movements last night; large varieties and numbers were reported across the state, the east, and the country today, and with migratory conditions still relatively good tonight, we should still see nice numbers of migrant woodpeckers, hummingbirds, flycatchers, vireos, thrushes, warblers, and sparrows tomorrow.

Cool! Good luck everyone!
