Heat Waves Expected Across Midwest, Bay Area Next Week

Several regions in the U.S. are experiencing a warming trend with temperatures rising as summer approaches. The Bay Area will see highs ranging from the mid-60s to mid-80s, with some areas reaching near 90 degrees by Friday. Illinois is expected to face a significant heat wave by late May, as the current cool pattern breaks down and temperatures climb, potentially accompanied by severe storms. Similarly, the Upper Midwest, including parts of North Dakota, will warm up with temperatures reaching the 70s and 80s by the weekend, with some areas potentially hitting low 90s by Sunday. This warming trend is expected to continue into next week, with mostly sunny skies and above-average temperatures across these regions. Overall, these forecasts indicate an early onset of summer-like conditions in multiple parts of the country.
