4Warn Weather – We will keep some sunshine and some clouds into the forecast for the end of the weekend on Sunday as we are heading into the upper 80s by Sunday afternoon. It will feel warmer and more humid for Father’s Day on Sunday as we could see heat index values into the upper 80s and possibly lower 90s for Sunday afternoon.
Looking ahead to next week, we are looking at our first sustained heat wave heading our way for the majority of next week. High-pressure will anchor itself down over the southeastern United States. North of the high-pressure center, we are looking at well above average temperatures across portions of the Midwest through the Ohio Valley, Great Lakes, and into the Northeast, including Metro Detroit.
This would mean near record temperatures for multiple days next week. High temperature is expected to be in the mid to upper 90s Monday through Friday, with heat index values going up to or above 100° each day once you factor in the humidity. Heat Advisories and/or Excessive Heat Watches and Warnings may be needed for most of next week for the region. To put this heat wave into some perspective, the last time we had 4 or more consecutive days of high temperatures in Detroit at or above 90 degrees was July 1-4, 2002. Based on the current forecast, this would eclipse that, making this one of the longest heat waves we have seen in over 20 years.
We are going to bring the chance for a few showers or isolated thunderstorms a few days next week with a few disturbances running around that high-pressure center over southeastern Michigan, but the day will not be a complete washout, and these would help to break the heat and humidity briefly. This part of the forecast is subject to change based on how the data changes and how strong the upper-level high pressure center strengthens over the region this week.
Take all your heat precautions next week, wear lightweight, loose fitting clothing, stay out of the sun for extended periods of time, stay hydrated and take care of our friends and neighbors.
