SHORT TERM. (Issued 330 AM CDT Sun Sep 19 2021)

Today:

High pressure over the eastern Great Lakes will continue to slowly push eastward throughout the day. This will allow southerly winds to develop and bring with it a much warmer air mass. Highs today are expected to be in the mid to upper 80s with a few areas hitting 90 towards south central and southwestern Wisconsin. Areas along Lake Michigan will be cooler in the 70s to low 80s. These temperatures are 10-20 degrees above normal for this time of year and Madison will only be a few degrees from its record daily high of 93 degrees set in 1948. Enjoy one of the last summer-like days and stay hydrated!

Tonight through Monday:

The remnants of Nicholas will be absorbed into the upper level flow and slowly track towards southern Wisconsin late tonight into Monday. The remnants will bring some 850mb warm air advection, moisture, and unorganized positive vorticity advection to the area causing some scattered showers and maybe a few thunderstorms for the morning and afternoon hours. Cloud cover and showers will help to keep temperatures cooler than today with highs in the mid to upper 70s across the area. It'll also be a bit breezy as the pressure gradient tightens ahead of a cold front to the west with gusts around 20-30 mph.

LONG TERM. (Issued 330 AM CDT Sun Sep 19 2021)

Monday night through Saturday:

An upper level trough is expected to lift across the northern Great Lakes Region Monday night into Tuesday. The associated surface low in central Canada is expected to deepen as it moves into the Hudson Bay area. This low will drag a cold front across Wisconsin Monday night into Tuesday. As the front moves through a line of showers/storms will develop. Out ahead of the front in the warm sector, the southerly winds are expected to be strong and breezy. Prolonged warm air and moisture advection will give southern Wisconsin PWAT values of 1.5 to 2 inches, which is above normal for this time of year. Its difficult to pinpoint the exact amounts of rainfall as guidance continues to show the upper level trough as a progressive quick moving wave. This could limit the amount of rainfall if the front moves through to quickly. The front is expected to clear southern Wisconsin Tuesday morning.

Cold air advection will set up behind the front bringing much cooler and drier weather to southern Wisconsin. Day time temperatures are expected to top off in the 60s and the overnight temperatures are expected to fall into the low 50s to mid 40s. The cool and dry weather is expected to persist across southern Wisconsin through the end of the work week. Looking into the weekend, guidance seems to be very polarizing with not much agreement between members or from run to run. There are some hints of another potential system, but given the uncertainty its to soon to say anything for certain.

AVIATION. (Issued 330 AM CDT Sun Sep 19 2021)

VFR conditions are expected through most of the forecast period. Light southeast to south winds are expected with a few cumulus clouds around 3500-5000 feet possible this afternoon. Some MVFR- IFR ceilings may move just north of the WI/IL border prior to 12Z Monday. These low ceilings will continue to push to the north through Sunday morning along with some scattered showers.

RAH

MARINE. (Issued 330 AM CDT Sun Sep 19 2021)

South to southeast winds continue through the day as high pressure over the eastern Great Lakes slowly shifts to the east. Winds and waves increase Monday into Monday night as the pressure gradient tightens ahead of a cold front that will push through late Monday night into early Tuesday morning. Winds and waves are expected to hit Small Craft Advisory levels late Monday morning into Tuesday morning and winds could approach gales Monday night into Tuesday morning for the open waters. Behind the front breezy northwest to north winds are expected into Thursday.
