Marine Weather and Tides
Two Rivers, WI

Version 3.4
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.

updated aviation portion for 00z TAF issuance

Short term Tonight and Thursday
issued at 331 pm cdt Wed may 23 2018
daytime cumulus clouds developed across much of the area late this
morning and afternoon, with the most coverage over northern wi
where the fewest high clouds were located and surface temps
climbed into the lower to middle 80s. The thicker high clouds
held down temps slightly which keep the daytime cumulus clouds in
check.

A dry evening is expected across the area, with the daytime
cumulus clouds fading away, but the higher clouds will continue to
drift across the region. Chance for showers and possibly a storm
arrive across central and northern wi later tonight into Thursday
morning as the upper level ridge slides to the east and moisture
increases as the low-level jet points into western wi and mn. Best
forcing and moisture stays to our west, so will confine pops to
central and north central wi. Very limited instability, so no
severe weather is expected. It will be warmer night across the
area, especially over the north, with highs mainly in the middle
50s to around 60 (cooler near lake mi).

Any overnight activity should weaken toward sunrise as the low-
level jet weakens, but additional showers and storms will be
possible through the day as models show instability building,
highest across central and north central wi, with capes in the
1-2k j kg range. Bulk shear values will be weak, generally under
20 kts, and no surface feature really to focus any organized
convection on, so while a few strong storms are possible, severe
weather is looking unlikely. Will keep pops on the low side,
highest across central and north central wi, with eastern wi
staying dry. 850 925mb temps climb a couple degrees by Thursday
afternoon, so for most locations will be slightly warmer than
today. Dewpoints hovering in the upper 50s to lower 60s will make
for a summer-like day.

Long term Thursday night through Wednesday
issued at 331 pm cdt Wed may 23 2018
thunderstorm chances are the main concern in the long term.

Instability ahead of an approaching mid level trough, and a
frontal boundary associated with a surface low moving across
southern canada, will bring a chance for showers to central and
north central wisconsin Thursday night. Rain chances increase and
spread across the rest of the area on Friday and thunderstorms
can also be expected. The showers and storms should persist
through at least the evening before winding down late Friday
night Saturday. Severe storms can't be ruled out, but shear is
not that strong and SPC only has a marginal risk of severe storms
for 12z Friday through 12z Saturday. Not really anything more than
slight chance pops for the rest of the weekend through the middle
of next week with surface high pressure and a mid level ridge the
main features in the region.

Expect warmer than normal temperatures, with lows in the 50s and
60s. Highs should be in the 70s and 80s, but it will be cooler
near lake michigan.

Aviation For 00z TAF issuance
issued at 636 pm cdt Wed may 23 2018
good flying weather expected tonight and Thursday, with just a
very small chance of a shower or thunderstorm late tonight and
Thursday across central and northcentral wisconsin. There is also
a chance of some low clouds along the lake michigan shoreline late
tonight and early Thursday.

Marine
Issued at 331 pm cdt Wed may 23 2018
moist air flowing over the cool waters of lake michigan will
continue to produce areas of dense fog. Not much change in
dewpoints or wind direction into Thursday, so fog is likely to
continue.

Fire weather
Issued at 331 pm cdt Wed may 23 2018
low rh values will continue this afternoon and evening across
northern and far northeast wi. An increase in moisture and shower
and thunderstorm chances are forecast for the end of the week
which could provide much needed relief from the dry conditions and
ease the fire weather threat.

Grb watches warnings advisories
None.

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.
