Another beautiful summer day around the Quad Cities as the dry, low humidity air allowed temperatures to top out well into the 80s.  This Pacific flow coming in from the west has dominated the hot dome of air that remains positioned along the southern half of the country.

The dry air in place will allow temperatures overnight to once again drop around the lower 60s under a bright full moon.

That leads us into the weekend and a few tweaks to the forecast.  Not changing the temperatures as highs will remain around the mid to upper 80s.  I’m still timing out a couple of boundaries that will get caught in this Pacific flow and bring a small chance for a shower or thunderstorm.

Here’s my tweak. The first arrives a bit earlier than what I talked about yesterday.  Instead of it being an after midnight event on Friday night, it appears that it will arrive by that evening after supper.  Nonetheless, the boundary is quite weak so a passing light shower or sprinkle is expected.  Coverage even looks widely scattered so not everyone will see that chance.

The second boundary is still on track to arrive during the pre-dawn hours on Sunday.  This may have a shower or thunderstorm with it before the rest of the day stays dry.

Looking ahead, next week still looks quite pleasant with temperatures trending cooler as the rain chance increases once again.
