Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 1111 AM CDT Fri Aug 14 2020

SHORT TERM. (Issued 335 AM CDT Fri Aug 14 2020)

Today through Saturday:

Patchy dense fog over the east will continue through sunrise, and then rapidly thin and diminish. Pockets of visibilities of one quarter mile or less will accompany the dense fog.

High pressure will influence our weather for one more day. As a result, fair conditions and light winds are expected with highs in the mid-80s today.

Clouds will increase overnight tonight as a cold front approaches from the west. We'll likely see a broken line of showers and a rumble of thunder or two approach our western counties in the early morning hours on Saturday. Models then depict much of this shower activity dissipating and skipping most of southern WI through the morning hours. During Saturday afternoon, redevelopment of showers along the front looks possible, with the best chance for thunder over far SE WI. Highs on Saturday will be in the upper 70s to low 80s for most as the passage of the cold front will blunt temperatures a bit. In far SE WI, temps will reach a bit higher owing to the cold front passing later in the day there.

LONG TERM. (Issued 335 AM CDT Fri Aug 14 2020)

Saturday night and Sunday:

Removed most precipitation chances Saturday evening across the eastern areas as first cold front is expected to be moving east at a slightly faster clip. Hence dry conditions are expected most if not all areas Saturday evening with a northwest breeze. A sharpening mid-level short wave rotating around long wave troffing shifting eastward across southern Canada will usher a secondary stronger cold front across southern Wisconsin late Saturday night and Sunday. Atmospheric moisture with this front appears to be a little more robust compared to 24 hours ago, but still not quite enough to tip the scales on adding small pops. Future shifts may be adding small pops including thunder for late Saturday night into Sunday. Most of the day Sunday will be dry with breezy west to northwest winds and temps recovering into the 70s under partly cloudy conditions.

Sunday night through Thursday:

Large upstream high pressure ridge over western CONUS into southern Canada will result in slightly cooler and drier northwest steering flow for the first half of this period, through Tuesday. 925H temps cool a couple degrees to around 17C, so after a cool start to the day, temps should rebound back into the mid to upper 70s. Onshore breezes will keep lakeshore areas a few degrees cooler during the day. Passing weak atmospheric ripples may bring a period of clouds to the area Monday night into Tuesday, but no precipitation is expected.

Upstream ridge begins to slowly flatten through the latter half of the week, which should allow warmer temperatures to return. Medium range guidance in general agreement on passing low pressure to the north of the Great Lakes Tuesday night and Wednesday carrying a backdoor cold front across Lake Michigan and Wisconsin. This front will be weakening as it moves south during this period but there may be just enough moisture and convergence to trigger a few showers. However too much uncertainty at this time to add small pops.

MBK

AVIATION. (Issued 1048 AM CDT Fri Aug 14 2020)

VFR conditions will prevail with east to southeasterly winds around 5 to 10 mph winds. Will see winds become light and variable again overnight and may see some patchy fog develop as well. Then clouds are expected to increase Saturday morning as a cold front pushes across WI. Scattered showers and thunderstorms will be possible along the front, which looks to push through southeastern WI mid-morning through the afternoon. Any showers/storms will likely be accompanied by lower ceilings and visibilities as well as some gusty winds. Then expecting a northwest wind shift and drier conditions behind the front.

Wagner

MARINE. (Issued 335 AM CDT Fri Aug 14 2020)

High pressure will influence weather over Lake Michigan for one more day. Expect fair conditions today with light easterly winds becoming northerly during the afternoon. On Saturday, a cold front will approach from the west, bringing chances for showers and storms over the lake mainly during the late morning hours and into the afternoon. Winds will become southeasterly ahead of the front on Saturday morning, then come around to northwesterly after the front passes in the afternoon. A period of gusty northwesterly winds looks possible late Sunday afternoon and into the evening.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
