Weekend Forecast: Friday Lows Dip Real Low, Then Hike Up Near 80 By Sunday

We have two interesting weather days over the next week, during which a 20-degree temperature swing will kick in only 48 hours apart.

After Thursday's relatively typical September weather, a cold front will pass by rather discreetly. Cooler air, now in southern Canada and Maine will rush into the area and keep Friday's temperatures nearly 10 degrees cooler than this afternoon.

After a cool Friday, morning lows Saturday will be in the 30s to lower 40s. Some areas well inland might see a light frost, but I am not expecting anything significant enough to worry about plants. Once the sunshine goes to work on Saturday, highs will rebound nearly 30 degrees, reaching 70 in the afternoon.

The second interesting day of weather comes Sunday — it's a September beach day! highs on Sunday will near 80, and with relatively light winds and an abundance of sunshine it will be a nice afternoon for the beach or lake. If your pool is still open, a dip will be in order that afternoon.

Another front approaches on Monday with a chance of showers as cooler weather returns for the start of the week. From a meteorological point of view, dry and sunny weather isn't that fascinating. We'll have to wait a while for some rain to make things really interesting.

Thursday: Mostly sunny with a high near 70.

Thursday night: Partly cloudy with a low in the lower to mid 40s.

Friday: Sunny and noticeably cooler. Highs around 60.

Saturday: A cool start with some ground fog, but otherwise mainly sunny and mild. Highs near 70.

Sunday: Mostly sunny with highs near 80.

Monday: A mix of clouds and sunshine with a shower possible. highs in the mid 70s.
