Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

UPDATE. Issued at 920 PM CST Mon Jan 20 2020
Lowered minimum temps along the Borderland as the prior forecast values have been exceeded. Made some other minor adjustments.
SHORT TERM. (This evening through Tuesday night) Issued at 249 PM CST Mon Jan 20 2020
Dry conditions will continue through Tuesday afternoon, with the next chances of precipitation moving into northwest Wisconsin late Tuesday night/early Wednesday morning. The main focus for tonight is on cloud cover and temperatures.
High pressure, which is currently situated over the South Dakota/Minnesota state border, will gradually slide east- southeastward tonight and Tuesday, with a dry air mass in place. As the high pressure system slides southward, there should be a period of good radiational cooling before a low-level jet dives southward late this evening and tonight, along with increasing warm air advection as winds turn southwesterly. The radiational cooling should help lead to the return of a low-level thermal inversion, which could lead to some low stratus development, which would then help temperatures recover. Winds could increase tonight as the low- level jet settles into the region. Overnight lows look to fall into the single digits below zero, but these temperatures may be too cold, depending on the warm air advection and enough wind to help keep the boundary layer well mixed.
Warmer still for Tuesday, thanks to the low-level warm air advection, with gradually increasing cloud cover. Highs Tuesday will warm into the upper teens to lower 20s - closer to seasonal average. Winds will remain from the south to southwest into Tuesday night, with a mid-level shortwave moving into the region. This should bring the next chances of precipitation, mainly to northwest Wisconsin. This precipitation could be a wintry mix of snow and freezing drizzle, depending on ice crystal growth aloft. Only light precipitation amounts are anticipated.
LONG TERM. (Wednesday through Monday) Issued at 249 PM CST Mon Jan 20 2020
The long term period will be riddled with p-type issues as a slow moving system crosses the South. It will allow a pool of warm air to ride up and over the cold air to the north and hang out for the week. This long period of warm air aloft will oscillate between an ice-bearing atmosphere and not throughout the week which will likely cause p-types to switch depending on the day, though it will be difficult to decipher with much confidence this far out. One thing to note is overall QPF amounts will be light throughout the week - cumulatively bringing a 0.10 to 0.25" Wednesday through Sunday.
Most of the energy potential for the week gets wrapped up in this system, so not expecting any large systems to march through. However, probably the most notable detail of the forecast will be the warm temperatures with highs residing in the low to mid 30s.
AVIATION. (For the 06Z TAFS through 06Z Tuesday night) Issued at 1133 PM CST Mon Jan 20 2020
VFR through the forecast. Expect LLWS to affect all terminals starting at INL early in the forecast, then impacting the remaining terminals from north to south through the early morning. The LLWS will continue through the rest of the forecast as a strong southwest low level jet is overhead.

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.
