Forecast confidence is high: high pressure will bring continued quiet weather to southern wisconsin through Saturday. Stubborn 5-7 kft clouds continue to hang around and may persist into the day today. If anything, there should be enough moisture for decent afternoon cumulus coverage today and again Saturday. There will be less clouds toward lake michigan under onshore flow. Temps through Saturday should be within a couple degrees of what was observed over the last day. Highs will remain a tad below normal for late august. Given light winds at night under the high and enough clearing, there could be some fog in the typical susceptible locations, though primarily within the wisconsin river valley. Long term Sunday through Monday night... Forecast confidence high... dry weather will continue through at least the daytime hours on Sunday, as high pressure pushes into northern new england. Temperatures should be in the mid to perhaps upper 70s. Rain thunderstorm chances start to increase late Sunday night, and especially into Monday, as two shortwaves approach from the west and southwest. There continues to be some significant differences within the guidance as to if and where the two waves phase, with the GFS favoring a slightly earlier onset to precipitation. Monday and Monday night should be most active for shower and thunderstorm activity, before a cold front moves through the region early Tuesday. Tuesday through next Friday... Forecast confidence moderate to |
high... fairly breezy west winds are expected for Tuesday and Wednesday, with the region situated between strong low pressure across northern ontario, and a large surface high over the southern plains. We'll likely be on the southern periphery of the shower activity associated with the upper low, so low pops seem reasonable for this time period. Another front is expected to swing through the area late in the workweek, with canadian high pressure building south as we head into labor day weekend. This should set the stage for temperatures a few degrees below average as we finish out the month of august. Aviation(09z tafs) Other than some patchy fog given enough clearing later tonight, vfr conditions are expected to continue over the next 24 hours. Clouds in the 5-7 kft range continue to linger and may persist into the day today. Even if these wipe this morning, late morning and afternoon cumulus clouds are expected, mainly away from lake michigan. Marine High pressure centered just north of lake superior early this morning will slowly slide eastward into the weekend, reaching maine by Sunday morning. North to northeast winds today will become easterly Saturday, with a southeast component by Sunday as the high moves on. Winds will be breezy at times through Sunday. Southeast winds will pick up Monday between an approaching low and the departing high. Winds and waves may reach small craft advisory levels. Mkx watches warnings advisories Wi... None. Lm... None. Today tonight and aviation marine... Ddv Saturday through Thursday... Boxell |

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. |
