Cold Outbreak for the Northeast is Forecast for April 22-24, 2009

A brief, but unseasonably cold outbreak is forecast by the GFS model for April 22-24, 2009. The upper air pattern is forecast to be highly amplified with a strong ridge at 500 mb across western Canada and a large trough over eastern Canada and the Northeast US. A cold pool of air or cutoff low at 500 mb is forecast over the Northeast during this time period. Snow is a possibility for interior New England and upstate New York during this time period as low pressure intensifies into eastern Canada. If this pattern verifies, there will be record low temperatures in the New York City area and across upstate New York and New England.
