Headline: Europe heatwave ends (briefly); Midwest U.S. rains via 12Z GFS.
Admin: Out of office Thursday.
Fig. 1-3: The 12Z GFS 6-10-day upper air forecast for Europe and medium-range upper air forecast for the U.S.
Discussion: The 12Z GFS indicates a cool/wet upper trough moving into West/North Europe to end the recent heatwave and push the heat toward the Black Sea region (Fig. 1). Unfortunately, Western Europe is likely to turn hot again in the 11-15-day period. In the U.S., the 12Z GFS is soaking wet in the Midwest States during the medium range (Fig. 2-3). Another Northeast heatwave is indicated for the 6-10-day period.
