What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

short term...

tonight and Wednesday... Forecast confidence is high.

Deep layer moisture will gradually wane into tomorrow as a drier
airmass advects in from the north. While the surface frontal zone
remains draped to our south, it should stay close enough for
scattered showers to continue into early Wednesday morning. With
both surface based and most unstable CAPE remaining tied to areas
along and south of the surface front, thunder chances appear
quite low and will pull the mention from the grids for tonight.

The 19.18z hrrr model solution does bring some weakening
convection close to racine and kenosha counties around 2-3z this
evening, but this solution is, as of yet, unsupported among the
other convective allowing models. If this solution appears more
plausible, it's possible that pops and QPF may need to be
increased in our far southeast tonight, but not willing to bite
off on this single model solution just yet. Temperatures will
remain on the cool side for tomorrow with northeasterly flow and
persistent cloud cover. Look for highs to range from the upper 60s
in the east to the mid 70s in the west.

Long term...

Wednesday night through Saturday... Forecast confidence is medium
to high:
a slow moving low pressure system will gradually pass by well to
the south mid to late week, eventually lifting northeast into
michigan by Saturday morning. Models are in pretty good agreement
with the track and timing of this system. There are some
differences though with the strength and moisture among models
though, which is impacting the resultant rain chances for southern
wisconsin. The GFS and NAM suggest mainly dry conditions through
Friday, while the ECMWF and canadian solutions would bring showers
to southern wisconsin Wed night through fri. The GFS remains dry
for sat, while the ECMWF and canadian have decreasing chances as
the low pulls away. Do have some slight chance to chance thunder
mention in with this low, but not very confident there will be
much thunder as most of the instability will remain to the south
of wisconsin.

Temps are expected to be 5-10 degrees below normal
through Saturday.

Sunday through Tuesday... Forecast confidence is medium to high:
there could be a few showers storms on Sunday as a week wave moves
through, with high pressure bringing a return of dry weather for
Monday. Showers and storms are then possible Tuesday as low
pressure moves through the area.

Temps should warm back up to around normal early next week.

Aviation(21z tafs)...

made adjustments to account for the persistent ifr lifr cloud
deck and drizzle over eastern areas. Based on upstream
observations, there may be some improvement by this evening, but
this has yet to materialize, so will stay pessimistic with the
ceiling forecast into this evening for now. May see brief
visibility reductions in vcsh this afternoon and evening, with a
rumble of thunder possible, but not likely. Look for improving
flight conditions for tomorrow during the late morning to
afternoon hours.

Marine...

look for scattered showers into this evening, with easterly winds.

Winds and waves will remain below small craft advisory levels
over the next few days.

Mkx watches warnings advisories
Wi... None.

Lm... Dense fog advisory until 10 am cdt Wednesday for lmz645-646.

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.
