Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 344 AM CST Mon Jan 18 2021

SHORT TERM. (Issued 331 AM CST Mon Jan 18 2021)

Today through Tuesday Night:

The bulk of the light snow has exited the area early this morning as the mid-level wave pushes east, but some patchy light snow/flurries including a plume likely induced by local industrial plant in Columbia county looks to linger this morning.

Another round of light snow/flurries will be possible this morning as radar imagery and observations upstream show a swath of light snow extending from northwest WI down through northeast/central IA moving east along cold front. Models suggest the band will dissipate with the drier air through the morning, but based on the latest observation trends, thinking the swath of snow despite battling the drier mid-levels as it pushes east, may have enough low-level moisture to hold on to produce some light snow/flurries across our western and central WI counties through the morning. However, not expecting there to be much in the way of impacts or accumulations if the band makes it into the area, other than a dusting to maybe a few tenths of inch at most leading to some slick road conditions.

Otherwise, expecting the drier air to become more prevalent through the day with light snow/flurry chances dwindling through the afternoon as the cold front pushes east. Clouds look to hold though, but temps are progged to be colder than previous days with high temps holding in the upper 20s to around 30 degrees and overnight temps falling into the teens.

There will be another chance for some light snow and flurries Tuesday afternoon/evening as another mid-level trough/clipper digs across the Upper Midwest and over WI. Again not expecting much in the way of accumulations with this quick moving system, but enough to probably cause some slick spots on roads especially given the colder temps. Tuesday temps are expected to top off in the upper teens to low 20s during the day and overnight lows falling into the single digits behind that system.

LONG TERM. (Issued 331 AM CST Mon Jan 18 2021)

Wednesday and Wednesday Night:

Sharpening short wave passing across southern Canada and the northern Plains will shift east into the Upper Midwest and western Great Lakes area during this period. This amplifying system will shift the steering winds temporarily to a more zonal flow which will allow warmer air to surge into southern WI. 925H temps increase to around 0C before cooling off slightly on Thursday. Low to mid level warm air advection starts in earnest Wednesday morning and continues into Wednesday evening ahead of approaching low pressure trof. Mid-level moisture remains sparse during these periods of synoptic lift, so wl continue dry forecast.

Thursday through Sunday:

A much stronger Arctic cold front will sag southward across southern WI Thursday night into early Friday. Mid-level moisture remains sparse, but the strong cold air surge may squeeze out some light snow showers or flurries Thursday afternoon and evening. Not enough confidence at this point however to introduce to the forecast. Cold air settles over the area on Friday as 925H temps drop to -10 to -15C. With the dry air getting reinforced over the area and increasing subsidence from passing high pressure, light winds and clear skies will allow temps to sink into the single digits Friday night and recover only into the upper teens to mid 20s. A few spots may fall below zero. Fortunately, winds will be lighter so wind chills will be minimal.

The protective high pressure ridge will move off to the east Saturday night as warmer air begins to move northward into the northern Plains and Upper Midwest associated with yet another amplifying low pressure area over south central Canada. Some of the Medium Range Guidance has this trof phasing with a southern stream area of cut-off low with a more organized area of low pressure moving somewhere into the region later Sunday night into Monday night, due to upstream eastern Pacific kicker. This is again looking like a potential mixed precipitation event for southern WI in the Sunday/Monday time frame. Although the usual uncertainties exist w.r.t to ptype, timing and amounts, there is enough agreement in the ECWMF ensembles, NBM, and a comparison of the last several deterministic runs valid Sunday and Monday to increase confidence on our next widespread precipitation event affecting the region late in the weekend into early next week. Hence bumped up POPS for Sunday into Sunday night. We'll be watching this once closely the coming week.

AVIATION. (Issued 331 AM CST Mon Jan 18 2021)

Some light snow/flurries chances will be possible across our western and central WI counties through the morning and may bring lower ceilings below 2 kft with it for a time. However, do not have high confidence for the lower ceiling and flurries as model soundings suggest some drying to occur as the swath of snow extending from northwest WI to northeast IA pushes east. Otherwise, ceilings ranging between VFR and MVFR are expected through most of the period with westerly winds.

Wagner

MARINE. (Issued 331 AM CST Mon Jan 18 2021)

Northwesterly winds will continue today into Monday as a weak area of low pressure moves across the northern Great Lakes. Northwest winds will continue on Tuesday as high pressure builds to the south of the Lake and a weakening surface wave moves across the Upper Mississippi River Valley. Then winds are progged to increase and shift to the southwest on Wednesday ahead of a strong low pressure that is expected to move across Manitoba and Ontario mid-week. Gales conditions are looking likely for this period before a cold front moves across the Lake late Wednesday into Thursday. Small Craft conditions are expected at times mid to late this week.

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.
