GEFS (mode) forecast for 2 PM Sunday. Cold front in Ohio Valley moving eastward will arrive late Sunday or Monday. High pressure in western Atlantic (H) has replaced the upper low and will bring much warmer, summer-like temperatures.(Click on image for a larger view.)

No sign of the usual summertime Bermuda High effect; it’s well out to our east.
