Area Forecast Discussion National Weather Service Green Bay WI 1026 PM CDT Mon Aug 3 2020

Updated aviation portion for 06Z TAF issuance

SHORT TERM. Tonight and Tuesday Issued at 234 PM CDT Mon Aug 3 2020

Mostly cloudy skies prevailed across the region this afternoon. The first hint of fall with temperatures in the 60s with dewpoints in the 40s to lower 50s. Northeast winds were still creating wave action on the bay and lake that may result in some minor flooding or beach erosion.

For the rest of the afternoon into this evening, a few sprinkles are still possible across northeast Wisconsin. As for the coastal flood advisory and for the potential for dangerous swimming conditions along the Lake Michigan beaches, winds and waves are expected to subside through the evening hours, thus will let the headlines end at 1 am on Tuesday, Skies will become partly cloudy across much of the area. Some patchy fog is possible in the typical cold spots across the north. Lows tonight will drop into the 40s north and west of the Fox Valley, and around 50 for the Fox Valley east to the lakeshore. The warmest low temperatures will be found across northern Door County where winds will be flowing over the warmer waters.

On Tuesday, skies will start out mostly sunny. Latest bufkit soundings would suggest fair weather cumulus clouds will develop by late morning and continue through the afternoon. Skies may turn mostly cloudy for a period of time on Tuesday. It will remain cool with highs in the upper 60s to lower 70s.

LONG TERM. Tuesday Night Through Monday Issued at 234 PM CDT Mon Aug 3 2020

High pressure will keep the area dry Tuesday and Wednesday. Temperatures on Tuesday will be below normal as the high drifts south of the region. By Wednesday temperatures will rebound to around normal as the high drifts south and flow becomes southwesterly.

Several weak shortwaves will bring a slight chance for showers and thunderstorms to the area Thursday and Friday, especially during the afternoon and evening hours with a boost from peak heating. Temperatures on Thursday will be around normal, however temperatures will creep up to a few degrees above normal by Friday as winds become southerly.

Temperatures will continue to rise this upcoming weekend and into early next week as the flow flattens out and becomes zonal, with better chances for showers and thunderstorms as more substantial low pressure systems approach the area. There are indications by the long term models that there could be an MCS or two that track through or close to the region this weekend into early next week. However the exact timing and strength of any of these systems this far out is difficult to ascertain as the extended models vary greatly that far out. However, it certainly bears watching in subsequent forecasts. Temperatures during this period will rise to a few degrees above normal in the lower to middle 80s.

AVIATION. for 06Z TAF Issuance Issued at 1026 PM CDT Mon Aug 3 2020

VFR conditions will continue through Wednesday, with daytime cumulus clouds above 4000' and clearing skies at night. Surface winds will be relatively light with good visibility.

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.
