SHORT TERM. (Issued 343 AM CST Wed Jan 27 2021)

Today through Thursday:

Northerly winds and some low level convergence are expected to develop a band of lake effect snow this morning, but this should remain south of the forecast area. Low level clouds will linger over the far southeast this morning before drier air pushes in allowing clouds to gradually clear by sunset. After the upper level trough passes through this evening we'll see increasing heights as a ridge moves overhead that will allow high pressure to build over the area.

Light winds and clear skies tonight will cause temperatures to drop below zero inland and into the single digits along the lake by Thursday morning. Another quiet day is expected Thursday with mid level clouds slowly building in from the northwest.

RAH

LONG TERM. (Issued 343 AM CST Wed Jan 27 2021)

Thursday night through Sunday night

We'll enjoy one more nice day Friday to end the work week with winds from the southeast and highs in the mid 20s to low 30s. Our next system to watch looks to arrive for the weekend as an upper level trough deepens over the east Pacific and makes it's way eastward into the Central Plains. At this point it looks like the main low associated with this trough will track through southern Kansas into eastern Missouri/western Illinois Saturday/Saturday night and then into the Ohio Valley Sunday. Precipitable water values increase over our area associated with some warm air advection but there is some uncertainty with how far north the precipitation will get. If there is a far enough push northward we could see some snow over the weekend. Expect more clarity with the timing and track of this system as we get closer.

Monday through Tuesday:

After the upper level trough clears high pressure returns to start out next week with highs in the low 30s.

RAH

AVIATION. (Issued 343 AM CST Wed Jan 27 2021)

MVFR ceilings over far southeast Wisconsin will slowly shift east this morning with VFR conditions and northerly winds expected through the remainder of the day. Cloud cover clears this evening with light northwest winds heading into Thursday morning.

RAH

MARINE. (Issued 343 AM CST Wed Jan 27 2021)

Northerly winds and waves will slowly diminish into Thursday as high pressure slowly builds over the area. Waves in the nearshore waters will be around 3 to 5 feet this morning, therefore the Small Craft Advisory remains in effect, but conditions are expected to gradually improve through the morning and afternoon as wave heights fall.

RAH

MKX WATCHES/WARNINGS/ADVISORIES. WI . None. LM . Small Craft Advisory . LMZ645-LMZ646 until midnight Thursday.

Small Craft Advisory . LMZ643-LMZ644 until 6 AM Wednesday.

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.
