*Another cool night ahead in the Northland with areas of frost especially over eastern portions of northwest Wisconsin including for the Ashland and Hurley areas.
*Frost/freeze potential will return to much of the Northland early next week (September 26-28 time frame)
*Cloud cover will be on the increase tonight into Friday morning with generally mostly cloudy skies expected during the day Friday and on Saturday too.
*Some rain is likely in the Northland Friday and Saturday but with the cool air mass in place, instability will be limited so we shouldn’t see much if any thunderstorm activity which will reduce the threat for heavy rainfall with this system, instead we’re looking at mostly light rainfall rates.
*Rain chances look greatest Friday evening into early Saturday morning, but there are chances for showers during the day Friday, and also on Saturday.
*Sunday is looking like the nicer day of the weekend, but even on Sunday there are chances for a few showers, but we should also see a little more sun on Sunday compared to Saturday.
The system which will affect the Northland over the next few days looks pretty strong today as it impacts the Rockies.

Maximum sustained winds: 130 mph (category 4 hurricane)
Fiona is moving north-northeast at 16 mph and has a minimum central pressure of 936mb/27.64 inches.
The center of Fiona will pass just west of Bermuda tonight, approach Nova Scotia on Friday, and move across Nova Scotia and into the Gulf of St. Lawrence on Saturday.
Central pressure of Hurricane Fiona is forecast to deepen from around 935mb this evening, to possibly as low as 920mb as it approaches Nova Scotia Friday night, that is an incredibly strong system!
500mb height anomalies with Hurricane Fiona could drop as low as -550 meters, some -5 sigma below normal. This really is an anomalous event!
Here’s a few different satellite loops of Hurricane Fiona — Loop time on all three ends 3:42 PM CT, Thursday, September 22, 2022.
