Update
No changes to the going forecast. Today should be a great day,
with seasonable temperatures and just a few passing clouds.

Marine
Quiet conditions are expected across the nearshore waters for the
next few days. Winds will generally be light from the north or
northwest through Wednesday. A cold front passing through the area
Wednesday will bring slightly stronger northwest winds, along with
a chance for thunderstorms.

Aviation(12z tafs) Areas of dense fog in the western cwa
should thin and dissipate after 7 am. More fog is expected later
tonight farther east. Otherwise,VFR conditions are expected.

discussion...

today and tonight - confidence... Medium to high.

Mainly mid-level clouds will spread into eastern areas this morning
as upper low over lower michigan retrogrades slightly westward.

Upper low further weakens and gets nudged to the east later today
and this evening, which should result in clearing skies this
afternoon. Any light showers or sprinkles are expected to remain
offshore.

Patchy dense fog has developed in the wi river valley overnight as
well as in sauk county per goes-16 imagery and surface observations.

However visibilities are fluctuating and webcams along interstate 90-
94 showing very little fog. Also, sauk county sheriff reported
areas of fog in the reedsburg and baraboo areas with thicker fog in
the spring green area. Due to transient nature of fog north of the
river valley, will hold off on dense fog advisory for now.

Daytime temperatures should be warmer today most areas due to more
sunshine and slightly warmer low level temperatures. Many western
areas should rise into the lower 80s.

Upstream cold front over western mn should further weaken as it
moves east into stagnant pattern across great lakes. However
associated short wave trough rotating around canadian upper low will
help to move remnants of cutoff lower mi low to the east tonight and
Tuesday. Lighter boundary layer winds over central CWA tonight
should allow fog to redevelop.

Tuesday - confidence... Medium
a high pressure ridge will be building towards the state from the
plains. Meanwhile the progs are showing some weak troughing lake
breeze convergence area with light QPF closer to lake mi. The
soundings look dry and the forcing does not look strong so will
leave forecast dry for now.

Wednesday - confidence... Medium
the surface high is proggd to drop southeast from the plains but
we will still be under the influence of the ridging for much of
the day. The GFS is faster to bring some cold front induced precip
into the CWA faster than the other models so restricting any pops
to the far northwest seems like a reasonable compromise at this
point.

Wednesday night and Thursday - confidence... Medium
better mid level dynamics arrive Wednesday night. A 500 millibar
low traversing near or north of lake superior will have some vort
lobes extending south that sweep through. Surface 850 frontal
zones will provide some lower level forcing that could sustain the
shra tsra into SRN wi. Progs do sustain some of this activity
into the CWA during the diurnally less favorable overnight period
though the marginal risk catches our northwest. Cold air
advection will dominate on Thursday in the wake of the fropa.

Cyclonic flow through an appreciable depth may lead to some shra
development. 925 temps will drop into the teens celsius so 850
temps proggd into the single digits celsius so a cooldown from the
pre-frontal airmass of Wednesday.

Friday through Sunday - confidence... Medium
500 millibar flow will remain broadly cyclonic with the cooler
regime in place. Vorticity maxima within this flow will lead to
some precip potential here and there but appears the more robust
convection will be focused to surface 850 boundaries with the more
unstable airmass well to our south.

Mkx watches warnings advisories
Wi... None.

Lm... None.

Update... Boxell
today tonight and aviation marine... Boxell
Tuesday through Sunday... 99

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.
