Forecast calls for Fourth of July scorcher
IRON MOUNTAIN — High temperatures in the low 90s are expected for the next few days as a sunny and hot Fourth of July weekend approaches.
There is a chance of showers this afternoon and tonight, but clear skies are predicted Friday. Partly cloudy evening skies are in store for fireworks on Independence Day.
Predicted highs at Iron Mountain-Kingsford are 91 today and 92 on Friday and Saturday. Overnight temperatures should dip into the lower 60s.
Sunday will bring more sunshine, with a high of 90, but a chance of afternoon showers and thunderstorms. Through most of next week daytime highs should range in the upper 80s, also with a chance of showers.
A jet stream with significant heat is bulging into the upper Midwest and Great Lakes, pushing temperatures well above normal, weather.com meteorologist Chris Dolce said.
“Weather conditions will be similar for each day during the coming holiday weekend,” he said. “The hottest temperatures compared to average will be from the Great Lakes to the upper Mississippi Valley, where afternoon readings are forecast to be 10 to 20 degrees above average.”
With July off to a scorching start, it’s no surprise the Climate Prediction Center calls for a 70% chance of above-average temperatures for Iron Mountain-Kingsford during the month.
“For precipitation, the July 2020 outlook indicates considerable uncertainty,” National Weather Service forecaster Jon Gottschalck said. The local forecast slightly favors above-average rainfall.
Beyond fireworks, Independence Day will end with a full moon and a penumbral lunar eclipse, which may create a visible shading on the moon’s face. The darkened moon is expected to be most evident at about 11:30 p.m. Central time.
The shading is due to the Earth blocking some of the sun’s light, covering the moon with the outer part of its shadow, also known as the penumbra.
