### Temperature Anomalies & Climate Notes
The forecast maximum temperature anomaly from Sunday, September 28 through Thursday, October 2 highlights well above normal temperatures across the Northern Plains, Upper Midwest, Great Lakes, and even portions of the Northeast.
An 850 millibar temperature anomaly map (about one mile above the surface) – a good indicator of surface temperature trends – shows dominant red and orange shading signaling above to much above normal temperatures. Blue areas, indicating cooler conditions, are minimal. Overall, above normal temperatures will remain firmly in control for at least the next 7-8 days, with only minor cooling possible late next weekend, coinciding with the first full weekend of October.
