HEADLINE: MID-DAY GFS A LITTLE WETTER IN THE DELTA..
North America: The 12z GFS is a little drier in the Great Lakes and wetter by 0.25-0.5″ through day 9 in the Delta and Ohio Valley. This is mostly associated with an uptick in scattered shower activity there early in week 2, as ridging persists through the middle of week 2 generally in the Midwest.
Europe: Europe will continue to be mostly drier than average through week 1, with no major changes to the forecast.
