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.

SHORT TERM. (This afternoon through Monday night) Issued at 252 PM CDT Sun Jul 12 2020
Sunday afternoon will continue to be a nice day with a chance for some showers across the northern Red River Valley into parts of northern Minnesota. Continued cumulus development is likely, but with instability remaining low across most of the region thunderstorms are not likely. There is some greater instability in the northern Red River Valley with ML CAPE around 1000 to 1500 J/kg, but with weak forcing not expecting much development. Can't rule out a rumble or two of thunder, but there should not be enough support for sustained thunderstorms this afternoon.
The main impact for this period will be Monday afternoon into Monday night. There will be forcing along a cold front moving across the Northern Plains with additional synoptic support from an upper trough. This combined with CAPE of 1000 to 3000 J/kg, 0 to 6 km bulk shear of 40 to 60 knots, and 0 to 1 km SRH up to 200 m2/s2 all severe threats will be possible. There should be enough inhibition to keep cells discrete initially, but as more cells initiate it could grow upscale later in the day. With this evolution there would be an initial supercellular threat before becoming a more linear wind threat. The linear threat would likely only be in parts of northwest and west central Minnesota based on the movement of the cold front. Precipitable water values around 1.5 inches, which is above the 90th percentile in NAEFS, will also provide for an excessive rainfall risk. Rainfall risk will be greatest near the international border and in northwest Minnesota although this will be very dependent on convection. This includes some areas with wet soils from recent rainfall in parts of far northwest Minnesota like the Hallock area. Rainfall totals will vary significantly across short distances in the discrete phase of the event, before a more uniform rainfall should the storms go upscale into a linear system.
LONG TERM. (Tuesday through Sunday) Issued at 252 PM CDT Sun Jul 12 2020
Seasonal heat returns and additional chances for thunderstorms late next week into next week. Severe weather impacts can't be ruled out at this time, but details are uncertain due to the nature of the systems and range in time.
Large scale pattern highlighted by quasi-zonal flow north of large scale ridging over the southern CONUS, with rising heights tendencies and shortwave ridging midweek. This should keep dry conditions in place midweek, and result in seasonably hot temperatures to return by the end of the week (highs back around or warmer than 90 by Fri). Consensus shows a shift to a more active much still warm pattern by next week as there is some indication west-southwest flow and additional waves could ejected eastward along the northern periphery of the mid-upper level ridge. Not a lot of confidence in the details at this range and there is increasing spread in finer details like QPF/Instability from GEFS plumes. Still, by the end of next week into the weekend an active pattern and at least moderate instability signal supports increasing thunderstorm chances with possibility for severe (details uncertain). Thickness values and 850 mb temps on GEFS plumes continue to show increasing trends, so while precip/cloud cover and brief shifts in surface features may allow for a brief/slight decrease in temps Sun overall trends should favor mid 80s to near 90 (if not warmer) into the next week.
AVIATION. (For the 18Z TAFS through 18Z Monday afternoon) Issued at 1242 PM CDT Sun Jul 12 2020
VFR conditions to continue for the rest of the day into tomorrow. Winds generally at or below 10 knots for most of this TAF period. Highers winds to start up tomorrow late morning, especially farther south at terminals like FAR. Most of the thunderstorm activity will be after this TAF period Monday evening into the overnight period, but some VCTS will be possible Monday afternoon at DVL.

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.
