HEADLINE: GFS SLOWER BUT A WETTER ACROSS CORN BELT WITH WEEKEND FRONT…

North America: The mid-day GFS is notably more bullish with storm development along the frontal boundary dropping south into the Midwest this weekend. The 12z is putting down 2″ over much of southern Iowa and northern Missouri, mostly on Sunday, and totals are also up ~0.5″ or so across northern portions of the Ohio Valley. Overall, the heavier totals are likely too widespread, but maxes in the central belt probably will approach 2″ even as the median precip is on the order of 0.5-1″. Otherwise no major changes as the front is a little slower to clear this run but the corn belt stays dry and cool into the start of week 2.

Europe: A hotter run for western Europe, with highs in the 90s in France and Germany persisting from Tuesday to Friday.
