Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 321 PM CDT Sun Jul 12 2020

SHORT TERM.

Tonight through Monday night . Forecast Confidence is high:

High pressure overhead tonight will gradually slide to the east Monday into Monday night. Light and variable winds tonight will become light out of the south tomorrow on the back side of the high. Temps will likely be just a little warmer tomorrow than today. Expect another round of later morning and afternoon cumulus tomorrow, with a lake breeze also developing again from mid to late morning.

Clouds will begin to increase from the west later Monday night ahead of an approaching low pressure system. These clouds along with continued southerly winds will result in overnight lows a little warmer than what is expected for tonight.

LONG TERM.

Tuesday through Thursday Night . Forecast Confidence is moderate

High pressure will slide east on Tuesday allowing southerly flow to return ahead of an advancing cold front. Shower and storm activity will develop along this front to the west and slowly approach southern Wisconsin during the overnight hours into Wednesday morning. Models hint that the coverage of precipitation may wane overnight along the front as it sinks into southern Wisconsin, then perk up during the daytime on Wednesday as a shortwave trough aloft approaches from the west. Likely pops have been continued for now during this time period, but may need to be adjusted as better certainty regarding the coverage is gained.

The ECMWF and the GFS have come into better agreement that Thursday will be dry as high pressure builds in behind the front.

Friday through Saturday Night . Forecast confidence is low

GFS and ECMWF solutions show chances for precipitation next weekend, but timing and coverage remain in question at this time. Models are also trending away from very high heat, but we could still have highs in the low 90s by Saturday.

AVIATION(21Z TAFS).

Clouds should decrease with the loss of daytime heating this evening, with mostly clear skies likely overnight. Another round of cumulus is expected Monday and could be briefly MVFR mid to late morning once again before bases rise to VFR by the afternoon.

A lake breeze will move inland again tomorrow by around mid to late morning.

MARINE.

Breezy northerly winds will continue into the evening between departing low pressure to the east and high pressure arriving from the west. A Small Craft Advisory remains in effect until 10 pm CDT from Port Washington southward. The high will move overhead tonight into Monday, bringing lighter winds to the area. Breezy southerly winds are then expected to develop Tuesday as the high slides eastward ahead of approaching low pressure.

BEACHES.

Breezy north to northeast winds will keep high waves going into the evening hours. A Beach Hazards Statement thus remains in effect for the Wisconsin Lake Michigan beaches from Ozaukee County southward until 10 pm CDT. Life threatening waves and currents are expected.

MKX WATCHES/WARNINGS/ADVISORIES. WI . Beach Hazards Statement until 10 PM CDT this evening for WIZ060- 066-071-072.

LM . Small Craft Advisory until 10 PM CDT this evening for LMZ644>646.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
