KEY MESSAGES

- Nearer to normal temperatures and less humid over the next couple of days

- Brief return of heat midweek with a chance of storms mid-late week

DISCUSSION (Today through Saturday)

Issued at 314 AM EDT Sun Sep 6 2026

Cooler and drier conditions will start off the new week behind the passage of a cold front and a Canadian airmass at the lower levels sagging into the Great Lakes region. Highs the next couple of days will stay in the 80s with lows dropping into the 60s and even 50s in some areas.

This return to near normal temperatures will only be short lived as upper ridging returns, bringing the heat back with it. Luckily this time the heat will be brief as the upper pattern is more progressive than was seen last week, allowing broad upper troughing to arrive mid to late week. A shortwave with this trough will bring with it another surface cold front and potentially a round of showers and storms. Confidence is growing in this round of rain mid to late week as models start to have better agreement on the timing of the wave. Temperatures are again expected to drop back to near normal again behind the wave and largely persist into the weekend. Models are hinting at another potential chance of storms late next weekend.
