Hot Week Ahead

August 31, 2015: It’s here!  The hot streak we’ve mentioned a few times since last week has arrived. We took a week-long break from our usual summer weather (5°-10° below average), and now are jumping from unseasonably cool to unseasonably warm (10° above average).

Last week’s weather stayed stuck in the middle 70’s.

Temperatures will stayed park at or near 90° for most of the first week of September, which will rival the hottest stretch of weather so far this summer.

August 14-17 is currently our hottest stretch of the year so far. We shouldn’t see many days in the 90’s in a row, but we will be close.

How does this work? The jet stream has retreated back to be north of the Midwest. This is allowing much warmer air to flood the region due to upper level winds from the southwest.  Strong high pressure will help reinforce this pattern, keeping hot air flowing into the region until Sunday.

Upper level wind pattern this week. The jet stream will direct hot air into the region.

It looks like the Labor Day Weekend will be hot, then temperatures cool dramatically back into the 70’s after the holiday. Enjoy the hot weather while it’s here (or keep reminding yourself: it’s only one week before we cool off again).
