Heat Advisory Into the Weekend
As you can see, the heat advisory extends from metro Detroit south to Alabama, southwest to Texas, and west to the Kansas-Colorado state line. There is another area of heat advisories along the southern Atlantic coast. It's not just metro Detroit; most of the center of the country is affected and a strip of the southeast.
As for how long this will go on, here's the forecast for the summer in Warmest spring in Detroit history on Examiner.com.
Based on the ending of La Nina in the eastern Pacific and the return to neutral conditions, the NWS Forecast Office predicts that the above normal temperatures will persist through July, for fifteen consecutive months of warmer than average weather... The warm streak should break in August, when normal to slightly below normal temperatures should return.So far, that prediction has been holding up.
