Area Forecast Discussion . UPDATED National Weather Service Milwaukee/Sullivan WI 1109 AM CDT Fri Aug 7 2020

UPDATE. (Issued 1110 AM CDT Fri Aug 7 2020)

Diurnal cumulus clouds are developing over southeast WI, along with a lake breeze. Cu are not as widespread inland as they were yesterday due to drier air through the column, despite the higher dewpoints.

SHORT TERM. (Issued 350 AM CDT Fri Aug 7 2020)

Today through Saturday:

Based on current obs and GOES-16 Night Fog band, beginning to see some pockets of patchy fog develop in Racine, Kenosha, Walworth, and Waukesha counties this morning with visibilities bouncing around and some spots falling below 1 mile at times. May continue to see additional pockets of fog develop across southern WI this morning as winds stay light, skies are mostly clear, and dewpoint depressions remain low, especially for low lying areas and river valleys. However, any fog should lift and clear out an hour or so after sunrise.

Otherwise, another quiet and dry day is expected across southern WI as a surface high continues to creep east into the eastern Great Lakes and the influence of an upper-level ridge continues across the Upper Midwest. Persistent southerly flow will continue to advect warmer and more humid air into the region. Temps are expected to be a few degrees warmer than yesterday with highs climbing into the low 80s.

Overnight should remain mostly dry with near normal temps, but a shortwave trough progressing across the Northern Plains today looks to trigger convection across the Dakotas and MN this afternoon and evening. As this wave pushes east, remnants from these storms will move into WI overnight into Saturday morning and may bring a few of the showers south into our area. There continues to be some difference in the models. The NAM and GFS favor this northern track with the shortwave trough overrunning the top of the ridge and keeping most of the precip north of our CWA, while the ECMWF is progging a piece of the mid-level energy from the shortwave trough extending further south, thus bringing remnants from the upstream precip into our CWA Saturday morning. CAMs are also depicting both scenarios being a possibility. Thus, there continues to be some uncertainty with the precip chances for early Saturday across southern WI. However, current thinking for Saturday morning is to favor the northern solutions, where most of the precip stays north, but having some of the remnants clip our northern part of the CWA before diminishing.

Despite what scenario materializes for Saturday morning, any precip or low clouds from this system should scatter out by the afternoon as the upper-level ridge remains in place across the region. Southerly flow will continue to advect warmer temps into WI with highs expected to climb into the mid 80s. Additionally, warmer temps will be present aloft and should keep southern WI capped limiting any additional storms in the afternoon and evening. Wagner

LONG TERM. (Issued 350 AM CDT Fri Aug 7 2020)

Saturday night through Thursday:

Should be a muggy night Saturday night into Sunday morning, with lows only falling to around 70. Strong capping aloft and the lack of forcing suggests dry conditions.

Sunday looks to be very warm, with highs in the upper 80s. For the most part think the daytime hours will be dry, though by late afternoon we may start to see some shower/thunderstorm activity approach from the west, as lift increases ahead of a cold front. That front is expected to move through the area Sunday night into Monday morning, bringing at least scattered storms to the area. Bulk shear will be marginal for severe weather, but with plenty of instability in place, a few strong storms are possible during this time.

The middle portion of the workweek will feature lower humidity and temperatures back to around average, with highs in the low 80s and lows in the low 60s. Humidity increases again heading into Thursday, along with a return of low end chances for showers and thunderstorms.

AVIATION. (Issued 1110 AM CDT Fri Aug 7 2020)

For the 18Z TAFs:

Today and most of tonight will continue to be quiet for aviation weather. There may be storms that track across MN tonight and into southern WI Saturday morning, but that is only one possibility. The other scenario is that nothing would happen in southern WI Saturday morning, but a few showers and thunderstorms could develop Saturday afternoon.

Cronce

MARINE. (Issued 350 AM CDT Fri Aug 7 2020)

An area of high pressure over lower Michigan will continue to slowly move east toward Lake Erie today into Saturday. Light southerly winds this morning are expected to increase through the day and then become breezier over the weekend, as the pressure gradient increases and warmer and more humid air advects into the region. With the increasing southerly winds, wave heights are expected to increase as well. Thus, hazardous beach conditions will be possible this weekend. Another system is expected later this weekend into Monday increasing chances for showers and thunderstorms as a cold front pushes southeast through the region.
