SHORT TERM. (Issued 343 PM CDT Wed Aug 12 2020)

Tonight and Thursday:

Pleasant and dry weather today is brought to you by an area of high pressure barely moving eastward across the region. Could maybe see a few high clouds creep into our western areas this evening from the remnants of this morning's MCS over southern MN, but given the dry vertical profiles on model soundings, it will likely not amount to much. Tonight should remain mostly clear as high pressure dominates. Temps are expected to be a few degrees warmer than last night with lows dipping into the up 50s to low 60s. Otherwise, these quiet and dry conditions are expected to continue for Thursday as the surface high slides a bit further east and mid-level ridge builds in overnight tonight. Southeasterly flow will begin to increase and bring warmer temps and dewpoints to southern WI with highs in the low to mid 80s.

LONG TERM. (Issued 343 PM CDT Wed Aug 12 2020)

Thursday night through Wednesday:

Quiet and dry pattern continues for Friday under the influence of the upper-level ridge. A bit warmer temps are expected as southerly flow continues to increase across the region as the area of high pressure pushes further east. Looking at daytime highs to climb into the mid to upper 80s with dewpoints in the low to mid 60s.

However, expecting the ridge to shift east later on Friday as a trough progresses across the Northern Plains. Models are in fairly good agreement with the trough moving into the Upper Midwest early part of the weekend and bringing a cold front across WI on Saturday. The upper-level dynamics look to remain well north of the area, but a few impulses of mid-level vorticity may eject out ahead of the trough and combined with forcing from the cold front and increased low-level moisture, will likely see some increased shower activity across southern WI on Saturday. From the latest models, there looks to be plenty of MLCAPE present to support thunderstorms along the front, but with the lack of deep layer shear not expecting much in the way of stronger convection at this time.

Northwesterly flow is then expected develop in the wake of the cold front on Sunday. Cooler air is progged to arrive later on Sunday with a reinforcing front that is expected to push through the area as another area of high pressure builds across the Upper Midwest. These cooler and drier conditions will continue in the start of next week with highs in the 70s.

AVIATION. (Issued 340 PM CDT Wed Aug 12 2020)

Still could see a few high to mid-level clouds push in across our western areas later this afternoon/evening, but mostly clear skies are expected as VFR conditions will prevail through the period as high pressure dominates across southern WI. Winds will mainly be light and out of the southeast through this evening before becoming very light and variable overnight. Then winds will increase to around 5 to 10 mph out of the southeast again by mid-morning on Thursday. Otherwise, quiet and dry conditions are expected for Thursday.

Wagner

MARINE. (Issued 340 PM CDT Wed Aug 12 2020)

Quiet and dry conditions will continue as high pressure over Lake MI slowly expands eastward through tomorrow with light and variable winds expected over much of the lake. The high will continue to slowly push eastward across the eastern Great Lakes and southeastern Canada Friday and Saturday with east to southeasterly winds increasing and then becoming more southerly during most of this period. Then a cold front is expected to push across the region this weekend bringing slight thunderstorm chances on Saturday and a northerly wind shift by Sunday.

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.
