Weather pattern next 2 weeks looks more like July than September

As fall advances, temperatures are supposed to get cooler. The upcoming upper-air flow doesn’t look like the rush to fall will be on in the next two weeks.

All forecast time periods are coming up warmer than average, and not only in Michigan and the Great Lakes. Most, if not all, of the U.S. is expected to be warmer than normal through the first few days of October.

Before we proceed, remember that an occasional day will fee like fall here in Michigan. The majority of the days will feel more like summer, however.

Here’s the temperature forecast for mid-September.

Temperature forecast September 14-18

There is a 60 percent to 75 percent chance of warmer than average weather in mid-September.

All of the U.S. is expected to be warmer than normal up to September 22, 2019. Remember the sun is losing heating power. So even though it will be warmer than average, it might not be hot. Several days well into the 70s or even into the 80s are expected into late September.

3 to 4 week forecast

NOAA is pretty confident temperatures will stay warmer than normal at least to October 4, 2019.

So what does this mean in real temperatures? By mid-September, Lower Michigan’s long-term average high temperature is 70 degrees in the north to 75 degrees in the south. Over the next three weeks, most of the days will have highs of 75 degrees to 80 degrees. There will be a few days well into the 80s, maybe even touching 90 degrees in an isolated spot.
