Relief from the heat and humidity finally arrives by Friday and continues into next weekend.
Today highs will continue to be in the upper 90s-low 100s with sunny skies and heat indices as high as 110°.
On all of those days, dew points of 60 or more and readings near 100 on the heat indices will make things just a touch more miserable. Sunday will be the apex of the heat - with temps possibly eclipsing 100 degrees - not factoring in the heat index. That means heat index values will be 107-112 in the afternoon. Temperatures will be slightly cooler on Sunday, but that is a relative term. Highs in the Twin Cities on Sunday should be in the lower 80s. The state recommends staying inside in air-conditioned buildings and avoiding strenuous activity to decrease the risk of heat-related illness. This is unsafe for anyone working outside and for those without air conditioning, it can be life-threatening. Anyone overcome by heat should be moved to a cool and shaded location.
"Know the signs and symptoms of heat exhaustion and heatstroke", the NWS advised.
The heat will stick around during the first week of July. At O'Hare International Airport the peak was 106 degrees, Mott said.
Temperatures will remain at 90, or very close to it, through Thursday, said another meteorologist, Benjamin Sipprell.
On Sunday, the sun will rise at 6:01:43 a.m. and set at 9:07:18 p.m.
INDEPENDENCE DAY: There will be a 30 percent chance of scattered rain showers and thunderstorms after 2 p.m.
There may be scattered clouds this afternoon, but abundant sunshine will effectively add another 5 to 15-degrees to the heat indices, making conditions extremely unsafe. Southwest wind around 8 miles per hour.
TONIGHT - Clear, Muggy and Warm.
The southerly winds will help keep low-level moisture in place. This will lead to heat indices ranging from 100 to 105.
