Updated national weather service milwaukee sullivan wi 929 am cdt Wed aug 21 2019 Update Could see a shower or two clip the southern forecast area today, but otherwise most places will remain dry. Looks like a mix of clouds and Sun through the day today. The forecast looks on track for the remainder of today. Marine Low pressure will move across ontario this morning and continue to drag a cold front across the lake today. North wind gusts of 15 to 20 knots are expected behind the front today. There will be a brief lull in winds this evening. Canadian high pressure will then move across ontario bringing another weak front across the lake by early Thursday. North winds will increase somewhat on Thursday as a result. As the high shifts east, northeast winds are expected Thursday night and Friday. Prev discussion (issued 624 am cdt Wed aug 21 2019) update... patchy fog is out there again this morning. A cold front over central wisconsin will move across southern wisconsin over the next few hours. It will bring light north winds and with sunrise don't expect fog to become dense. Aviation(12z tafs)... patchy fog early this morning. A cold front will move through this morning bringing light north winds. There may be a few gusts of 15 to 20 mph during the afternoon. Ceilings may briefly be MVFR this morning as the front moves through. Not expecting it to be widespread or long enough of a duration to include in tafs. Otherwise expect scattered to broken clouds around 3-4kft today. Skies will clear later this afternoon. Light northeast winds will prevail on Thursday. MVFR ceilings may move in from the lake on Thursday, otherwise scattered clouds around 4kft will dominate. Prev discussion... (issued 308 am cdt Wed aug 21 2019) short term... today and tonight... Forecast confidence high. A cold front will move through early Wednesday morning as a trough of high pressure extends from canada into the northern plains. It will bring north winds and drier air mass. Clouds are expected during the morning along and behind the front, but then they will clear during the afternoon. An upper low will be parked over ontario into Thursday. A shortwave will pass by to our southwest in the evening but the atmosphere will be very dry. With clear skies we are looking at lows in the middle 50s. Thursday... Forecast confidence high. Surface high pressure will move into ontario pushing another weak |
front southward across the state. Winds will become northeast during the afternoon. Flow off the lake may bring some clouds into the east, knocking temperatures down a few degrees during the afternoon. The NAM and GFS are showing some precip with the front while a strong shortwave will also be moving through. Soundings show moisture is pretty shallow so will keep a dry forecast. Long term... Thursday night through Saturday... Forecast confidence high... skies will clear later Thursday night as high pressure is reinforced across the great lakes. This should set the stage for a cool morning on Friday, with lows in the low 50s. Highs Friday will top out in the low to mid 70s. Nearly identical conditions are expected for Saturday, as the surface high remains centered just north of lake superior. Sunday through mid week next week... Forecast confidence moderate... winds will become more southeasterly on Sunday, with moisture very slowly returning to the area. Sunday should still be dry, with highs just a touch warmer in the upper 70s to around 80. An approaching shortwave from the west will attempt to phase with a wave moving through the ohio valley, and this may bring a few showers to the area as early as Sunday night. It's very possible that dry low levels win out, however. The high will shift fully east of the area for Monday, with south to southwest flow expected at the surface, and west-southwest flow aloft. There should be several chances for showers and thunderstorms Monday and Tuesday, with rain potential continuing into Wednesday as another cold front approaches from the west. Aviation(9z tafs)... expect some fog this morning. A cold front will move through this morning bringing north winds. Scattered to broken clouds around 2500- 4000ft will accompany the front this morning. There may be a few gusts of 15 to 20 mph during the afternoon. Skies will clear later this afternoon. Light northeast winds will prevail on Thursday. MVFR ceilings may move in from the lake on Thursday. Marine... a cold front will move down the lake this morning, reaching the southern part by late morning. North winds will gust 15 to 20 knots. There will be a brief lull in winds Wednesday evening before north winds will gust 10 to 20 knots late Wednesday night into Thursday. Northeast winds are expected Thursday night and Friday.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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. |
