Cooler, More Seasonable Days Ahead

July 6, 2012 1 Comment

We’re in the seventh, and most likely final day, of our current 90°+ heat wave as a cold front looms to our northwest, poised to swing through the area tonight, bringing relief from the scorching heat and heavy humidity.  In the meantime, heat indices today (Friday) are as high as anything we’re experienced this year with triple digits being found just about everywhere in the region.  An Excessive Heat Warning remains in effect for the entire viewing area until 10:00 tonight as afternoon highs will be in the mid to upper 90s and dew points in the mid 70s will create heat indices from 100 to 115.  While there will certainly be some chances for showers and thunderstorms later this evening and tonight, the activity looks scattered to sparse with light amounts of rainfall expected and widespread severe weather a small possibility.  Behind the upcoming cold front, we’ll have dew points in the 60s for the weekend with high temperatures in the 80s, creating afternoon heat indices in the mid to upper 80s, a vast departure from the triple digit stuff we’ve been experiencing all week long.  It looks like the cooler, more seasonable weather will persist through the weekend and next week, meaning 80s will be more common than 90s and humidity should be a little more tolerable.  Unfortunately, rainfall potential looks lower as well as only slight chances exist in the next 7 to 10 days.

The jet stream is currently located to our north in southern Canada, allowing a large, hot air mass control the midsection of the U.S.

The jet stream will take a dip to the south this weekend and for the early part of next week, allowing cooler air to invade the heart of the U.S. while the west and southwest will be much hotter.

    I hope you are right. Headed to N Shore Saturday for some Superior Hiking Trail and do NOT want rain. Predicted 55-75 looking perfect.
