Updated aviation portion for 18Z TAF issuance

SHORT TERM. Today . Tonight . and Wednesday Issued at 320 AM CDT Tue Aug 11 2020

A sunny and warm, but much less humid day is expected today, in the wake of yesterday's cold frontal passage. Highs should be in the upper 70s to middle 80s, with comfortable dew points in the upper 40s to middle 50s. West winds will gust to 15 to 20 mph by afternoon.

Clear skies and diminishing winds may lead to patchy fog development late tonight, especially over the favored areas of central and north central WI. Good sleeping weather is anticipated, with lows in the 50s and lower 60s.

On Wednesday, have ignored the outlier GFS model, which produces a significant area of rain over northern WI in the afternoon. Will keep our dry forecast intact, with high pressure remaining over the western Great Lakes. Temperatures may a degree or two warmer than today, with highs in the lower to middle 80s inland. Developing light southeast winds will keep readings a little cooler along the lakeshore, where highs should be in the upper 70s and lower 80s.

LONG TERM. Wednesday Night Through Monday Issued at 320 AM CDT Tue Aug 11 2020

Zonal pattern at 500mb will continue into the weekend, which will result in temperatures at or slightly above average. Later in the weekend into early next week, 500 mb ridge expected to build across the western United States with a downstream trough across the Great Lakes. Temperatures early next week will fall to or slightly below normal for mid August.

Dry conditions are expected Wednesday night as high pressure lingers across the Great Lakes. Like the last few night, models have differing solutions when precipitation chances arrive late in the week. Low confidence in the small chances of rain on Thursday across portions of central and north-central Wisconsin as the new GFS/NAM/ECMWF keep the forecast area dry. For Thursday night, convection is expected to break out across Minnesota and western Wisconsin. The GFS/NAM/Canadian try to spill some of the precipitation into our western counties towards 12z Friday although the ECMWF remains dry. The same holds true for Friday as the ECMWF remains dry while the other models have some precipitation across our far western counties. Did lower rain chances across the east Thursday and Thursday night, and won't be surprised if they will be lowered on later shifts for the Friday period.

For the upcoming weekend, chances of showers and storms are in the forecast. Low confidence at the moment in when and where to place the highest chances of rain over the weekend due to timing differences in the models. Humidity will increase slightly each day into the weekend before humidity levels drop off early next week.

AVIATION. for 18Z TAF Issuance Issued at 1235 PM CDT Tue Aug 11 2020

Good flying conditions are expected the next 24 hours as a weak anticyclone passes south of the area. Patchy fog is possible tonight, mainly in central and north-central Wisconsin. Included a tempo group for 2SM FG to the KCWA/KRHI TAFs with this issuance.

GRB WATCHES/WARNINGS/ADVISORIES. NONE.

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.
