328 pm cdt Sun aug 18 2019

Short term
Tonight and Monday... Forecast confidence is medium to high.

Cin continuing to erode over eastern CWA this afternoon as surface
trof moves through the region. Not seeing any agitated CU from
latest visible imagery, but wl continue a small pop for an
isolated shower or storm redeveloping into the early evening.

There is also a small contribution from the left exit region of
the upper jet grazing the northeast cwa. The lingering frontal
boundary may cause a few showers or storms to graze the far
southeast during the night as well.

Otherwise, expect clearing overnight, but some sct-bkn cloud
cover may linger for a time into the evening. Boundary layer
mixing and drier air will prevent fog development in eastern areas
later tonight. However the boundary layer winds will subside
later tonight in the west due to approaching ridge. This should
allow areas of late night fog in low areas and river valleys.

A pleasant and less humid day lies ahead for Monday with high
pressure settling over the area. A lake breeze will keep lakeshore
areas slightly cooler in the afternoon.

Long term
Monday night through Tuesday night... Confidence is medium.

Expect mostly quiet conditions to continue through Monday night.

On Tuesday low level moisture will increase, but a decent cap and
dry air aloft may prevent any showers or thunderstorms from
developing during the afternoon and early evening as the cold front
approaches. Have left slight chances for Tuesday, but if trends
continue chances for showers and thunderstorms could be removed by
the next forecast issuance.

Wednesday through Sunday... Confidence is medium to high.

Cooler temperatures filter in for Wednesday and the rest of the
workweek with highs remaining in the 70s. High pressure will bring
sunny skies to the region and keep any rain chances out of the
area until the weekend. Rain and thunderstorm chances for
Saturday and Sunday are low at this time due to variable
guidance solutions. Current thinking though is that the weekend
will be mostly dry with better chances for rain holding off until
next week.

Aviation(21z tafs) Scattered to broken MVFR clouds have spread
across most of the area this aftn. Latest satellite imagery show
lower clouds looking cellular over most of the area so expect a
decreasing trend in the late aftn and early eve with loss of
insolation. Patchy fog will likely develop later tonight in low
areas and river valleys, especially over western cwa.

Marine Still expect gusts to reach 22 to 25 kts for several
more hours over the nearshore waters while low level mixing
continues. Hence small craft advisory will remain in effect until
23z. Brief period of strong gusts over parts of northern lake
michigan as occluded front moves through this area. Gust to 35 kts
at northern mid-lake buoy at 19z. The wind gusts should be mostly
25 to 30 kts for the rest of the aftn into the early evening
before gradually subsiding overnight. However, northwest winds
and low level cool air advection in wake of passing front will
continue to generate gusty winds tonight, especially over the
northern part of the lake. High pressure settling over the
southern great lakes on Monday will result in light winds into
Tuesday.

Mkx watches warnings advisories
Wi... None.

Lm... Small craft advisory until 6 pm cdt this evening for lmz643>646.

Tonight Monday and aviation marine... mbk
Monday night through Sunday... Rar

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.
