Highlight: Soaking wet week in southwest Great Plains. Fig. 1: A soaking wet southwest Great Plains forecast by 12Z GFS for this week. Discussion: The 12Z GFS 144-hour rainfall forecast at midday features heavy rain across the southwest Great Plains drought zone (Fig. 1). Additionally, a streak of heavy rain is also projected for central portions of Minnesota. However, the Midwest States are generally dry or with light rainfall. The 12Z GFS medium-range temperature anomaly forecast (Fig. 2-3) maintains the warm Northwest to North-central U.S. pattern while the South and East stay biased cool thanks to an intense negative phase North Atlantic oscillation (-NAO). The June 9-15 U.S. population weight CDD forecast edges warmer to slightly above normal cooling demand (Table 1). Fig. 2-3: The 12Z GFS medium-range temperature anomaly forecast.
