Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 337 AM CDT Tue May 11 2021

SHORT TERM. (Issued 337 AM CDT Tue May 11 2021)

Today through Wednesday:

Frost Advisory continues until 8 AM CDT this morning for the entire forecast area. Skies are clearing over most of the area, though some mid-level patches may continue to move through. Despite this, light to calm winds should allow temperatures to slide into the lower to middle 30s in most areas.

Models are in good agreement with high pressure slowly shifting southeast into Wisconsin from northern Minnesota today into Wednesday. This will bring a period of quiet weather, with light winds allowing for lake breezes this afternoon and Wednesday afternoon.

There should be scattered to broken diurnal stratocumulus clouds developing by midday into the afternoon each day, with forecast soundings showing deep mixing with some weak instability. Influence of 500 mb cyclonic flow also helping with the diurnal cloud development. Highs today will be cool, with upper 50s to around 60 well inland and lower 50s near the lake.

Another cool night is expected with clear skies and weak winds tonight into early Wednesday morning. Lower to middle 30s for lows look likely again, so another Frost Advisory may be needed for this period. A milder day is expected Wednesday, with middle 60s well inland and 50s near the lake.

LONG TERM. (Issued 337 AM CDT Tue May 11 2021)

Wednesday night through Monday:

A large high pressure area around 1030 mb will be centered near the WI and IL border and srn Lake MI for Wed nt-Thu. Aloft, a small portion of the departing upper trough will become cutoff near the WI and IL border, while shortwave ridging occurs over the nrn Great Lakes. Low level instability will continue to support scattered cumulus during the day for Thu-Fri.

Weak shortwave troughs will then move across the region within nwly flow aloft for Fri nt-Sat nt. The large high pressure area will weaken but only shift slightly to the east. Moisture will be delayed with just small chances for showers. Temps will gradually warm through the week and may finally warm to normal values by late week.

For later Sunday and Monday, the jet stream will become more wly with a shortwave trough or two in the flow with the usual uncertainties on strength and timing. A wave of low pressure and warm front will lift newd from the central Great Plains but it is fairly uncertain if it will make to srn WI. Elevated warm, moist advection and lift could still bring showers as long as the system does not stay too far south. Nevertheless, deeper convection will likely remain to the south.

AVIATION. (Issued 337 AM CDT Tue May 11 2021)

Clearing is occurring over most of the area, though some mid-level patches of clouds may continue to slide southward into the morning. Light and variable winds into this morning will become north by midday into this afternoon.

Lake breeze with northeast winds are expected by midday and linger this afternoon for terminals near lake. Scattered to broken diurnal clouds are expected by midday into the afternoon, with any ceilings remaining 8000 to 10000 feet AGL.

Clear skies and light/calm winds are expected again tonight into early Wednesday morning. Southeast lake breeze and scattered to broken mid-level diurnal clouds expected by midday Wednesday and into the afternoon.

MARINE. (Issued 337 AM CDT Tue May 11 2021)

High pressure over northern Minnesota will slowly push southeast through the region today into Friday. North winds today across Lake Michigan will become light and variable tonight into the rest of the week.
