UPDATE. (Issued 930 PM CDT Mon Jun 14 2021)

Skies are clearing nicely across srn WI. Light winds and radiational cooling will drop temps into the lower to middle 50s for most of the area by sunrise Tue. As heating ensues nnely winds will increase once again with scattered to broken high based cumulus by afternoon well away from Lake MI. Temps will range from the lower 70s near Lake MI to the lower 80s over south central WI. High pressure that is currently over south central Canada will finally arrive over srn WI for Tue nt-Wed eve.

SHORT TERM. (Issued 309 PM CDT Mon Jun 14 2021)

Tonight through Tuesday night:

A south-southeast moving shortwave will shift through during the evening hours. A few showers may linger into dusk, primarily for lakeshore locations. Can't rule out a rumble of thunder, provided one of the storms manages to utilize the meager elevated CAPE of 250 J/kg that RAP soundings show. Modestly gusty north winds will gradually die down as the shortwave exits and the influence of high pressure continues to fill in tonight. Tomorrow, another shortwave will slide from north to south across the state. Models do depict a few sprinkles to light showers over central Wisconsin during the afternoon, but sfc moisture will be lackluster, so not confident on anything reaching the ground with that activity. Winds may pick up along the lakeshore as the shortwave shifts overhead and drags a cold front with it. Temperatures will remain seasonable again tomorrow, as winds will generally remain northerly.

LONG TERM. (Issued 309 PM CDT Mon Jun 14 2021)

Wednesday through Monday:

300mb ridging and a broad sfc high centered over the upper Great Lakes will allow for dry conditions and clear skies on Wednesday and north winds should continue to moderate temperatures. Thursday, the ridge axis aloft should shift eastward over Wisconsin, and the high pressure will shift into the lower Great Lakes Region. This will bring sfc winds around to southerly and southwesterly, and warm advection should increase, leading to a potentially hot day. Models depict a moist axis approaching Thursday afternoon and, during the evening hours, dewpoints should increase ahead of a potential complex of thunderstorms. It's too early to say how much rain these potential storms will bring or if these storms will even materialize, but there is some model agreement for a stormier period Thursday night.

Beyond, a collapsing front scours moisture behind these storms, and high pressure builds in for the later hours on Friday into the weekend. Temperatures will stay seasonable, as they will be moderated by north winds again.

MARINE. (Issued 309 PM CDT Mon Jun 14 2021)

High pressure of 30.4 inches will gradually build into the area today and Tuesday. Winds will remain somewhat light overnight and a few showers and a rumble of thunder or two may occur over the midsection of the lake along the Wisconsin shoreline through the early evening hours. Winds will pick up again Tuesday afternoon as a shortwave and cold front drop southward down the barrel of the lake. Lighter winds Wednesday will be followed by increasing southerly winds Thursday ahead of an approaching low and thunderstorm activity Thursday night.
