Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 902 PM CDT Thu Aug 13 2020

UPDATE. (Issued 902 PM CDT Thu Aug 13 2020)

The sfc ridge extending across the Great Lakes will linger over srn WI into Fri or Fri eve. Thus another pleasant night tonight and another warm day for Fri. A milder night is expected Fri nt as a milder and more humid airmass begins to move into the region.

Gehring

SHORT TERM. (Issued 315 PM CDT Thu Aug 13 2020)

Tonight through Friday night:

Looks like we will get another day of dry and quiet weather through Friday as the surface high gradually slides east and an upper-level ridge continues to build across the region. Increasing southeasterly flow will advect warmer temps and more moisture into the area with highs in the mid to upper 80s and dewpoints climbing into the mid 60s. Meanwhile, a broad upper-level trough will be digging across Central Canada and the Northern Plains and begin to move into the Upper Midwest later on Friday bringing a more active pattern into the first half of the weekend.

LONG TERM. (Issued 327 PM CDT Thu Aug 13 2020)

Saturday through Thursday:

As the upper-level trough pushes further east on Saturday, it will drag a cold front across the region. Models have been fairly consistent over the past few runs with the timing and placement of the cold front across WI. Looks like the cold front will push through southern WI late Saturday morning/afternoon. With ample moisture (PWATs around 1.0-1.5 inches) streaming into the region combined with lift from the front itself, expecting to see increased shower chances on Saturday. However, QPF amounts are still in question as the GFS is trending drier while the ECMWF has a bit wetter, but portions of southern WI should see some rainfall.

In addition to the showers, there will be chances for thunderstorms to develop along the cold front. With the frontal passage progged to push through late morning/early afternoon, the environment may not have too much time to destabilize, but still expecting to see MLCAPE values around 1000-1500 J/kg, which would be sufficient for storms. With the better upper-level dynamics and more favorable deep layer shear remaining further north, not expecting too much in the way of stronger storms across southern WI. However, a few storms with gusty winds cannot be ruled out at this time, especially for areas in far southeastern WI that have more time to destabilize before the front's arrival or if the front tracks slower allowing for more widespread destabilization. Overall not to enthralled with storm chances on Saturday at this time, but will continue to monitor trends over the next few runs.

Otherwise, as northwesterly flow develops in the wake of the cold front, dry air will filter into the area for Sunday. Then, higher pressure is expected to build across the Upper Midwest on Sunday. This will bring a reinforcing front across the area later on Sunday and cooler conditions with highs in the 70s and lows in the 50s are expected for the early part of next week. By mid-week could see a weak disturbance makes its way across the western Great Lakes and bring some showers to the area, but due to its uncertainty this far out, confidence is not real high at this time.

AVIATION. (Issued 902 PM CDT Thu Aug 13 2020)

For the 06Z TAFs:

Mostly clear skies and VFR conditions for Friday into Friday night.

Gehring

MARINE. (Issued 313 PM CDT Thu Aug 13 2020)

Dry and quiet marine conditions are expected again for Friday as an area of high pressure extending across the Great Lakes slowly pushes further east across southeastern Canada. Light to moderate east to northeasterly winds are expected until becoming more southeasterly Friday into Saturday. A cold front is then expected to push across the lake Saturday into Sunday morning with winds veering to the northwest. A period of gusty northwest winds will be possible on Monday as high pressure builds in behind the front.
