Lake Breeze Calms Storms

***Watch WISN 12 News for the latest weather information!***

Here is a quick update to get your weekend started. The chance for showers and t-storms will continue until about 2-3 a.m. Saturday. With that said, as of this writing on Friday evening, showers and t-storms were having a hard time moving east toward Milwaukee. This was because a lake breeze pushed inland to near the Jefferson and Waukesha county line on Friday afternoon.

The lake breeze dropped our temperatures back to the low 80s, and pushed inland a more stable airmass. The storms moving toward Milwaukee were then hampered as they tried to overcome the slightly more stable airmass.

Below is the surface map at 3 p.m. Friday. Notice the southeast to east winds closer to Lake Michigan…that was due to the lake breeze. Farther inland, the surface winds were more south-southeast.

After the final chance of showers/t-storms slides by after midnight, mainly dry weather should take hold. Below is the short range high resolution model we use daily. This has the bulk of the storms north or south of our area at 2 a.m.

While the threat for heavy rain is possible Friday evening and night, the focus will be mainly for inland areas and locations closer to the Illinois border. Certainly a few showers or t-storms are possible, but I think most people will be able to rest easy tonight around Milwaukee.

If you have a rainfall total, please post it to the comments section of the blog. One total I saw from Madison was 2.50″ of rain!

Have a great weekend, and enjoy a dry and warm Saturday!

  1. Are there going to be any fog issues tomorrow morning for the PGA again?

    • I would say no…the winds should turn southwest there overnight. The last 2 days of the event look good!


  2. I am curious about the stable air mass. In looking at the nature of the storms, they appeared to be more high based. based on the LCLs and sounding data. If this is the case, I would think the instability would be more in the mixed layer vs. surface layer and the surface wind may not have affected it too much. Maybe a bit. In looking at the LI/mid layer lift, it was lower in your area than to the west. Perhaps not quite enough extension of the large scale ascent to push it with the same oomph in your area. Perhaps with the earlier convection – that contributed to a bit of subsidence and stabilization. Dunno.

    Just thinking out loud…

  3. We were fortunate up here in NE Dodge County, only one small thundershower last evening. I don’t know if the lake breeze caused showers up this way to be less intense like they did elsewhere, but we lucked out and didn’t have a lot of rain.

    I noticed this morning that the air feels less humid already. Skies are clearing and we are looking forward to a great weekend. Hope yours is too.
