Fxus63 kmkx 161437 afdmkx area forecast discussion national weather service milwaukee sullivan wi 937 am cdt Sun jun 16 2019 Update Mid-level wave moving across the area has resulted in continued light showers and drizzle this morning. Visible satellite presentation of the cloud cover suggests the thicker clouds and likely drizzle extends to ia wi border. Updated pops to show a slower end to the light rain and drizzle this morning. The cooler northerly flow coupled with the slow to clear clouds will keep temps well below normal as some locations may not make it out of the upper 50s and lower 60s today. Marine The fog and low clouds continue across the southern portions of the lake. Webcams and observations would indicate a slower clearing of the fog then previously forecast so have extended the marine dense fog advisory until 20z this afternoon. Some models suggest a brief clearing of the fog later today then possibly moving back in overnight and another dense fog advisory might be needed tonight. Winds of 10 knots or less out of the north are expected as a weak upper level system crosses the area. Then high pressure building in to our north with bring lighter winds to the area. Prev discussion (issued 345 am cdt Sun jun 16 2019) discussion... today and tonight... Forecast confidence is medium... remnants of a mesoscale system in association with weak low pressure will push across the region today with mostly light showers associated. The low and mid levels will remain moist for much of the region but will decrease into the late morning from southwest to northeast. Some forcing in the upper levels will continue into the late morning as well. This will keep us with chances for precipitation through the late morning, primarily in the northern parts of the cwa. However, expect showers to end by the early afternoon as higher mid level moisture and upper level forcing pushes out of the area. Clouds, however, will stick around for much of the day with not much clearing expected. Otherwise weak high pressure will build across the region later today into tonight keeping the region dry. Monday... Forecast confidence is high. High pressure will bring us a dry day here, but cloud cover is a bit in question. The better chance for Sun will be north of milwaukee and madison as low pressure will be passing by well south of wisconsin. Look for highs in the 70s, but the cool onshore flow will keep the lake shore counties cooler. Tuesday and Wednesday... Forecast confidence is medium. We do see some mid level short wave energy push in here on

Tuesday... Mainly passing by to the north. Moisture is rather limited, but it could produce some showers over south central areas in the afternoon. Overall, Tuesday is looking decent with highs in the 70s. Better mid level troughing and associated surface low push through the midwest on Wednesday. The ECMWF keeps the bulk of the showers storms south of wisconsin, while the GFS has a larger inverted trough extending deep into wisconsin, resulting in scattered showers and storms on Wednesday. The gem is similar to the gfs, so will keep the mention of precip going on Wednesday. Thursday through Sunday... Forecast confidence is medium. We may get a dry day in on Thursday. The GFS is the odd model out, keeping showers storms going across the area with a deeper surface low pushing through NE indiana on Thursday. The gem and ECMWF are weaker and more south with the surface low and therefore try to dry it out across southern wisconsin. Will need to keep a slight chance mention of rain going due to the uncertainty, but Thursday is trending dry. That dry trend should continue into Friday. The guidance really begins to diverge with respect to pattern features and timing for next weekend. Saturday is looking wet as low pressure pushes through, but the ECMWF lingers the threat through Sunday while the GFS tries to dry things out. Aviation(09z tafs)... showers continue to make their way across the region causing some temporary reduced vsbys in any pockets of heavier rain but generally the main concern remains CIGS and vsbys across southeastern wisconsin which remain below 500 ft with areas along the lake having vsbys from 1-2 miles with periods falling as low as a quarter mile. This will last at least into the early morning hours as fog over the lake pushed inland. Fog will begin to dissipate as the Sun comes up and should be gone by the late morning hours as the system finally pulls through the region. In other parts of southern wi CIGS remain around 1-2 kft and will continue into the morning and afternoon with much of the region likely to fall below 1000 ft for a period today. Marine... dense fog advisory remains over the southern half of the lake as light winds and high moisture continue to play a factor in allowing for fog to remain across the lake. Dense fog should dissipate by the late morning as this system pushes out of the region. Otherwise there are no other concerns as tonight through Monday looks quiet due to high pressure building into the region. Mkx watches warnings advisories Wi... None. Lm... Dense fog advisory until 3 pm cdt this afternoon for lmz080-671- 673-675-777-779-870-872-874-876-878. Update... Stumpf today tonight and aviation marine... Ark Monday through Saturday... Davis

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.

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