Much of the second half of August has featured cooler-than-average temperatures, and that trend looks to stick with us to kick off September as well. We will see a few days with highs near 80° around Labor Day weekend, but another sharp cool down will follow for the middle of next week. This deep trough, or dip in the jet stream, will slide in from Canada between Wednesday and Thursday, bringing a cooler and breezy stretch for the second half of the week.

The strong cold front arrives early Wednesday, which likely only allows highs to reach the low or mid-70s before a sharp drop in temperatures late that evening. Overnight lows will likely reach down into the low 50s and upper 40s Wednesday and Thursday nights. Afternoon highs Thursday will likely top out below 70°.

Thursday just kicks off the cooler stretch, as we maintain a high chance we will see below normal temperatures through the first week of September. Climate Prediction Center gives us a 70-80% chance to see below average temperatures between the 3rd and 7th of the month. This likely means a few days of highs near/below 70° and lows in the 40s and 50s.
