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.

SHORT TERM. (This evening through Saturday night) Issued at 259 PM CDT Fri Apr 3 2020
Uff-da, that pretty much sums up the reaction to folks as they walk out the door today to temperatures that are 25 to 35 degrees colder than 24 hours ago. This afternoon, the main upper low was visible on radar with a line of broken returns from Redwood Falls up through Long Prairie at 230pm. It is forcing out ahead of this upper wave that allowed widespread precipitation to form over eastern MN this morning that is now over southeast MN and western WI. Short term models have a pretty good handle on this precipitation, so followed a blend of them to work PoPs out of western WI this evening. Fortunately, as the day has worn on, the warm nose aloft has started to cool off, allowing p-type to switch over to snow, but a period of freezing rain is likely through about 6pm for Eau Claire up through Rusk counties in WI before the warm nose cools down enough over there to end precip as all snow. Didn't really make any changes to the advisory, as timing for when this wintry precipitation finally hit our eastern tier of counties will limit impacts out there, though a slushy 1-2 inches of snow on grassy surfaces is likely across most of our WI counties.
Behind this upper wave, there is strong subsidence, as evidenced by the drying on water vapor imagery moving across SoDak. This subsidence will help scour out clouds this evening, with mainly clear skies expected tonight through tomorrow, with nothing more than some increasing mid-upper level clouds Saturday night as WAA kicks in. Despite the sunny skies, 925mb temps near 0c will mean we only see highs in the 40s on Saturday. Saturday night, high pressure will be centered over WI. Clear skies and calm winds means temperatures Sunday morning could end up a few degrees lower than currently forecast over western WI.
LONG TERM. (Sunday through Friday) Issued at 259 PM CDT Fri Apr 3 2020
Temperatures will continue to warm Sunday with WAA continuing into early next week. Highs will be in the mid to upper 50s for most Sunday, and low to mid 60s on Monday and Tuesday. There will be some 70s possible across southern MN Tuesday. The best chance of area wide precipitation will be Monday night and Tuesday. Development of a nocturnal LLJ will provide enhanced forcing. Tuesday will need to be watched for the potential of thunderstorms with deeper mid level lapse rates and 40 to 50 kt deep layer shear depicted by guidance. Timing is going to be one of the key factors for severe potential Tuesday afternoon. Some models are slower with the cold front allowing more instability to build up while others are faster with the FROPA and that would limit potential severe development. The one trend the with all of the 12z guidance was to be a little faster with this system, with the attendant strong to severe thunderstorm threat shifting southeast as well.
The rest of the forecast period will trend cooler than normal with northwestern flow developing. Both European and American forecast ensembles continue to favor below normal temperatures continuing into Mid April.
AVIATION. (For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1251 PM CDT Fri Apr 3 2020
Precipitation has become widespread over eastern MN and western WI at the start of the period in response to forcing ahead of the main upper wave that has finally started moving into MN. This precip started as a FZRA/PL mix, but is quickly changing over to snow from west to east. For timing p-type changes and moving this precip out, followed a timing close to what the HRRR has. Extensive stratus sits across MN in the wake of this forcing. Subsidence immediately behind the leading edge of the mid-level wave is helping scour clouds out and we're finally starting to see the back edge of the clouds move out of the Dakotas. Previous TAFs had this clearing timed fairly well and all we really did with the 18z TAFs was move this clearing up an hour.
KMSP . MSP has gone to snow, but is also near the back edge of the precip already. Gave the ending of snow a little breathing room with the 1930 end time, though it will likely end before then. Hi-res models have swung in to pretty good agreement that stratus clears out around 2z or 3z
