UPDATE. (Issued 950 PM CST Sat Jan 16 2021)

Went with patchy freezing drizzle over south central WI into the overnight in addition to very light snow or flurries. Some icing reports from the west side of Madison to the Blue Mounds area, but more widespread icing in far wrn WI and the state of IA where temps are colder. The very light pcpn tonight is within cyclonic flow and ahead of a shortwave trough that will track from nrn MO into the Ohio River Valley tnt-Sun. If the freezing drizzle becomes more widespread a Winter Wx Advisory may be needed.

SHORT TERM. (Issued 255 PM CST Sat Jan 16 2021)

Tonight through Sunday night:

Some flurries and isolated light snow showers will be possible this evening. Southwest portions of Wisconsin and areas along the WI/IL border may see a light dusting of snow late tonight into Sunday with a mid level trough digging to our southwest. Most of the lift (500 mb positive vorticity advection) will be better to our south but we could see enough locally for some light snow. Temperatures will be below freezing so some slick spots will be possible Sunday morning. Any accumulating snow will exit the area by Sunday evening but some lingering flurries will remain possible across much of the area.

RAH

LONG TERM. (Issued 255 PM CST Sat Jan 16 2021)

Monday through Saturday:

We'll be in northwest flow through most of next week with multiple shortwaves moving through, but it looks like there will be plenty of dry air so precipitation chances will be low at this time. These shortwaves will bring periods of colder air than what we have seen in a while. Highs tuesday are expected to be in the teens and 20s with lows potentially getting into the single digits Tuesday night.

RAH

AVIATION. (Issued 950 PM CST Sat Jan 16 2021)

Areas of MVFR Cigs tnt-Sun nt. Patchy freezing drizzle and flurries over south central WI tnt with flurries to the east. Local Cigs below 1 kft south and west of Madison. Very light snow and flurries for Sun.

Gehring

MARINE. (Issued 255 PM CST Sat Jan 16 2021)

Northwest winds will continue through the weekend and gradually become lighter and waves decreasing in height. Winds become more westerly Monday as high pressure builds into the area. We'll have to watch for the potential for gales over the open waters next week as a low pressure system tracks through Ontario Wednesday night into Thursday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
