PREV DISCUSSION. (Issued 912 PM CST Tue Feb 18 2020)

UPDATE . The forecast is on track for tnt-Wed.

MARINE . Brisk northwest winds will continue into the early morning hours over Lake Michigan due to the passage of another cold front. The brisk winds will then weaken toward sunrise. A large high pressure area around 30.8 inches will move from the northern Great Plains to the Ohio River Valley through Friday. Modest west to northwest winds will continue until winds increase and back to the southwest on Friday. Some gale potential will exist Friday and Friday night across the northern reaches of the lake. A Small Craft Advisory is in effect until 3 AM Wed from Sheboygan to Winthrop Harbor for brisk northwest winds.

PREV DISCUSSION . (Issued 553 PM CST Tue Feb 18 2020)

UPDATE . A dry cold front will pass this evening with another burst of cold advection on nwly winds. Sfc temps are expected to fall into the single digits by sunrise Wed, and possibly below zero toward central WI. Wind chill temps will range from zero to 10 below zero until late morning. A shortwave trough will approach and pass through the area for Wed aft-nt. This will bring sct-bkn middle to high clouds to srn WI but no pcpn.

AVIATION(00Z TAFS) . VFR conditions tnt-Wed.

PREV DISCUSSION . (Issued 200 PM CST Tue Feb 18 2020)

DISCUSSION .

Tonight through Wednesday night . Forecast Confidence is High .

Mainly clear skies are expected tonight as an Arctic high pressure begins to build into the region. A weak upper wave moving across northern WI could bring some scattered clouds across the north tonight. But the main message is going to be the colder temperatures expected with lows in the single digits to a few degrees below zero in the far NW. While we do have some slight breezes holding on overnight, think that we should be able to drop pretty quickly and ended up going below guidance by a few degrees. Wind Chills drop below zero for much of the area and could be in the negative teens north of I-94 tonight.

The CAA continues for Wednesday and highs end up in the teens, which for this time of year is more representative of our normal lows. The coldest night of the week will occur Wednesday night into Thursday with lows below zero for much of the area with the exception of the immediate lake shore. Wind chills drop down into the negative teens for Thursday morning and this is going to be close to our Wind Chill Advisory criteria and something to keep an eye on.

Thursday through Saturday night - Confidence . High Core of coldest air/lingering influence of low level thermal trough will still be lingering across the area early Thursday. The surface high will shift east and set up a waa regime into the weekend. All in all quiet weather to prevail.

Sunday and Sunday night - Confidence . Low to Medium One point of concern for the second half of the weekend is that the GEM is bringing qpf with a system northeast into the area but it is an outlier at this point with the GFS and ECMWF keep the low and associated precip shield to our south.

Monday and Monday night - Confidence . Low to Medium A brief period of ridging is likely though some lingering lift associated with 850/925 baroclinic zone is possible which is played out a little more on the GFS. This is likely what the init pops are keying on.

Tuesday - Confidence . Low The GFS and ECMWF organize a surface low to our southwest in response to amplifying southwest mid level flow. The GEM is once again showing itself as an outlier with a low suppressed much further south of the other models. Will have some pops in place for the precip potential on northern side of the low. Precip type with this system looks uncertain as well.

AVIATION(21Z TAFS) . VFR conditions expected through the period although some SCT clouds near 3,000-3,500 ft could clip the northern portions of the area tonight. Winds stay breezy out of the NW into this evening before gradually tapering off overnight.

MARINE . The strong pressure gradient between the departing low and incoming Arctic high will keep winds gusty across the lake into the evening hours before dropping below Small Craft Conditions. Periods of sub-small craft conditions are expected this week as the high moves in. Winds begin to shift to the SW on Friday and could see a return of gusty winds to small craft conditions. A few gale force gusts are possible Friday in the far northern portion of the lake.

MKX WATCHES/WARNINGS/ADVISORIES. WI . None. LM . Small Craft Advisory until 3 AM CST Wednesday for LMZ643>646.



Update . Gehring Tonight/Wednesday and Aviation/Marine . Stumpf Wednesday Night through Tuesday . Collar

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
