Temperatures on a downhill run this week

The good news is that Chicago area temperatures soared as high as the lower 80s Sunday as morning cloudiness and a few passing sprinkles gave way to brilliant afternoon sunshine. The bad news is that Sunday’s highs will likely not be approached again this week. Cooler air will be filtering into the area in the week ahead as jet stream winds turn northwesterly, sending air of Canadian and arctic origin into the area. Most days should see highs in the 60s and lower 70s right into the Memorial Day weekend.
Hot air is making an early season statement in areas from the southern Plains to the desert Southwest. Temperature records tumbled Sunday from Louisiana to southern California. The Dallas area recorded its second consecutive 99º record high while blistering triple-digit heat set records in the Southwest, including Needles (114°) and Palm Springs (112°) in California, and Tucson (109°) and Yuma (110°) in Arizona.
