Birding Forecast, week beginning 30th August

Summary of week's weather: A light northerly will persist until Wednesday when a depression will move in from the west. A westerly airflow will then be established until at least the weekend. The jet stream will form a unbroken corridor across the North Atlantic. 

Light Northerlies over much of UK for early part of week 
A westerly airflow across upper North Atlantic by end of the week 

 Jet stream situation by end of week 

Birding Forecast

Local Birding/London: Early part of week is most promising with light northerlies and some easterlies over Scandinavia which could push passerine migrants into North Sea which in the light wind conditions could trickle down across a broad front and in land . With a westerly airflow established by mid-week there could be some channelling of migrants such as hirundines as they deflect back towards the continent. As the westerlies establish migration will dry up. 

Kent Coast Easterlies across parts of Scanadanavia could push migrants into the North Sea which could get channelled south in the light northerly so drift migrants are a possibility. The light northerly could also maintain the run of seabirds on the North Kent coast. As the westerly establishes later in the week and considering the extent of the jet stream an american wader or waterbird is an outside possibility. High arctic waders moving south will still push south so good chance of more juvenile Curlew Sandpipers, Little Stint and Ruffs etc in the early part of the week. 

Elsewhere The westerly airflow, incoming depression and jet stream situation looks promising for american waders arriving in the west and also seawatching potential of west and south coasts. 

Birding Plan (if I had the chance to implement it all)
Monday: A bit of local birding to look for migrants in the light northerly airflow
Tuesday and Wednesday: North Kent coast to scour for migrants, seabirds and waders.
Thursday to Saturday: Locate to Cornwall for sea watching and looking for american waders. Tacumshin in Ireland would be another good place to look for american waders.
