303 am cdt Mon aug 26 2019

Short term (today through Tuesday)
issued at 303 am cdt Mon aug 26 2019
an upper level long wave trof, and its associated surface low will
affect the forecast area today. By afternoon, the upper wave will
evolve into a cut off upper low, while the surface low meanders
around central manitoba, before reaching northwest ontario by the
late afternoon. Embedded pieces of energy will rotate through the
area today, while a cold front slowly moves into the western tier of
the forecast area by late afternoon. Rain will become more organized
and affect all areas, from west to east, through the day. Only
expecting isolated thunderstorms as the instability is weak.

Beneficial rain will occur with amounts up to and around one inch
today over the western two thirds of the region. Lower amounts over
the arrowhead and north central wisconsin which will not see the
efficient rainfall rates until afternoon. Flooding should not be an
issue as the soils have been very dry, and the area of rain and
storms will be progressing steadily across the region today.

The circulation around the upper surface low tightens up as the
system deepens tonight. Additional impulses will rotate across the
area, while the cold front moves through the region. Isolated
thunderstorms will be possible in the early evening with some
marginal instability, which is lost with sunset. Best rainfall rates
will occur over the eastern third of the region in the evening with
around one inch in the arrowhead, and one half to near an inch for
north central wisconsin. Lighter amounts overnight as a break from
the embedded impulses occurs.

The upper low and surface low become vertically stacked Tuesday
over northwest ontario. Additional upper energy moves through the
region, accompanied by cold air advection, with some of the coldest
air since early spring. 850mb temps are forecast to drop into the 5
to 8c range. Some isolated thunderstorms are possible over the
southern third of the area from late morning through the afternoon
due to weak instability.

Long term (Tuesday night through Sunday)
issued at 303 am cdt Mon aug 26 2019
the upper trough will continue to slowly move through the region
with the axis of the trough moving east of the northland Wednesday
morning. Cool temperatures will be in place with 850mb values
forecast to be from 4c to 6c 12z Wednesday. These cool temperatures
combined with the upper low will keep showers in the forecast
Tuesday night into Wednesday, although chances will diminish from
southwest to northeast on Wednesday as ridging moves toward the
region as the upper trough departs and warm advection develops.

Highs Wednesday will only be in the upper fifties to mid sixties and
gusty west northwest will make it feel even cooler.

Another cold front will move through the region Thursday and the gfs
and ECMWF are in better agreement tonight compared to their last few
runs. The upper level support will remain near or north of the
international border and we have low pops across northern minnesota
for now and amounts should be light.

A dry period is expected Thursday night through Saturday night as
high pressure moves through the region. Highs Friday and Saturday
will be in the sixties.

A southward moving cold front late next weekend will bring chances
for showers and thunderstorms to portions of the region but
significant rainfall appears unlikely.

Aviation (for the 06z tafs through 06z Monday night)
issued at 1227 am cdt Mon aug 26 2019
widespreadVFR conditions late this evening will give way to MVFR
ceilings overnight, and ifr ceilings after sunrise this morning
through the day today. A cold front, which is currently draped over
central north dakota, will slowly make its way into the northland
late this morning, and continue tracking eastward, bringing showers
and some embedded thunderstorms with it. While severe storms are not
expected, some heavy rainfall will be possible, which should bring
visibilities down into MVFR ifr. Winds will remain from the
southeast today, which could be gusty at times. As the cold front
passes through this afternoon and evening, winds will shift more
westerly tonight.

Marine
Issued at 303 am cdt Mon aug 26 2019
winds are expected to back to east to southeast today and be from 10
to 15 knots as an area of low pressure and cold front move into
minnesota. Waves will build along the north shore to 2 to 4 feet
late today into this evening, mainly north and east of silver bay.

Showers will become widespread with a few thunderstorms also
possible. Low pressure will deepen as it moves through northwest
ontario tonight into Tuesday morning. The wind will switch to west
later tonight and increase into Tuesday and continue Wednesday.

Sustained winds will be from 15 to 23 knots Tuesday into Wednesday
with gusts of 25 to 35 knots. A gale watch warning may be needed for
Tuesday into Wednesday for portions of western lake superior.

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.
