UPDATE. (Issued 834 PM CDT Sun Jun 20 2021)

Thunderstorm moving toward Rock county showing nice elevated core. Will be watching closely for pulling trigger on SVR. Otherwise, expect scattered showers and storms to continue through the late evening as short wave trof and cold front move through. Instability gradient draped across northern Il will continue to allow stronger storms to flirt with the far south.

Kavinsky

SHORT TERM. (Issued 446 PM CDT Sun Jun 20 2021)

Tonight and Monday:

Widespread rain and clouds continue to hold back any potential instability ahead of approaching low pressure and associated cold front. Some clearing well west of the forecast area has allowed for storms to fire this afternoon. The storms will continue to head this way late afternoon into the evening, with current timing putting the main line into the western forecast area by around 9 pm. Starting to see some models catch on to the lack of instability here though, suggesting storms may largely wipeout or at least decrease in intensity as they arrive. With some sunshine not too far to the west/southwest of the forecast area, could still see some CAPE get pulled into the area ahead of the front, so will hang on to the potential for some strong to severe storms later evening into tonight, particularly toward Illinois.

Any showers/storms that do survive through southern Wisconsin are expected to exit to the east by 12 or 1 am as the cold front pushes through. Gusty winds and lingering clouds are expected behind the front into Monday, with some sunshine possible by afternoon. Cooler temps aloft and the lingering clouds will result in temps not getting out of the 60s most locations, though a few places east may crack 70.

DDV

LONG TERM. (Issued 446 PM CDT Sun Jun 20 2021)

Monday night through Sunday:

Brief period of much cooler air arrives Monday night into Tuesday under northwest flow aloft. Min temps Tuesday morning should be into the 40s region wide!

Southwesterly low level flow quickly kicks in on the back side of the ridge with the low level jet running from the southern Plains up through Wisconsin Wednesday and will bring the next small chances for rain in Tuesday night into early Wednesday. The LLJ picks up in intensity later in the week and could lead to some better chances for seeing convection. It'll also lead to some warmer temperatures and higher sfc dew points.

Halbach

AVIATION. (Issued 834 PM CDT Sun Jun 20 2021)

Scattered showers and a few thunderstorms will continue through late evening as short wave trof and cold front move through. More widespread lower clouds in the cold air advection are expected later tonight into Monday for a time, with breezy northwest winds.

Kavinsky

MARINE. (Issued 446 PM CDT Sun Jun 20 2021)

Low pressure will continue to approach this evening, moving across northern Lake Michigan tonight. Northwest winds will pickup behind the low and associated cold front tonight into Monday, with gale force winds likely across the northern third of the lake. Winds may approach gale force at times farther south. Kept the Small Craft Advisory timing as is and issued a Gale Warning for Monday into mid-afternoon for the northern 1/3 of Lake Michigan. Lighter winds are then expected Monday night into Tuesday as high pressure moves through the region.
