Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 901 PM CST Mon Nov 30 2020

UPDATE. (Issued 901 PM CST Mon Nov 30 2020)

With cold cyclonic flow aloft, clouds have been very slow to clear this evening. A mid level vort max is expected to finally push east of the area after midnight, and subsidence behind this feature should help with clearing late tonight.

Lows are still on track to settle into the upper teens across the west to low to mid 20s east.

SHORT TERM. (Issued 200 PM CST Mon Nov 30 2020)

Tonight through Tuesday night:

Combo of low level thermal trough and broadly cyclonic flow keeping cloud cover in place. 500 millibar cyclonic shear zone proggd to depart this evening with 925/850 RH progs showing a drying trend. So expect to see some clearing as the night wears along with the western areas getting in on this first. The pressure gradient will ease some but by and large things are sluggish to move much due to slow northward movement of strong low to our east. Surface and mid level ridging tries to gradually work in here through Tuesday night but suggestion in progs is that it makes only our western cwa by later Tuesday night.

Collar

LONG TERM. (Issued 200 PM CST Mon Nov 30 2020)

Wednesday through Monday:

Quiet early December weather looks to be the rule this period. Models have been pretty consistent with this being a period of inactivity with modifying temperatures as the week goes on. Progs are showing a cold front dropping in around Sunday which will collapse the thermal profile though this cool-down looks to be short-lived.

Collar

AVIATION. (Issued 901 PM CST Mon Nov 30 2020)

MVFR to low end VFR ceilings remain in place across the eastern half or so of the forecast area, with cloud bases generally between about 2800 ft and 3300 ft. The clearing line has been making very, very slow progress to the east tonight, but should accelerate slightly late tonight, with mostly clear conditions expected by morning. Clear skies will prevail through the day on Tuesday.

Winds will remain gusty from the northwest through the night tonight, especially across the eastern terminals. Breezy conditions are expected for much of the day on Tuesday as well.

Boxell

MARINE. (Issued 200 PM CST Mon Nov 30 2020)

With pressure gradient and obs still indicative of gale gusts, the gale warning looks good through this evening. The nearshore small craft also looks good into the better part of Tuesday. Pressure gradient slackens a bit for Tuesday though a steady northwest wind will persist. However may see some uptick in the northwest winds again later Tuesday into Tuesday night to near gale levels especially across the northern portions of the lake.

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.
