Marine Weather and Tides
Remer, MN

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.

Short term (today through Monday)
issued at 351 am cdt Sun jun 24 2018
a weak flow pattern continues for the area today, with a weak cold
front slowly oozing south across northern minnesota. Aloft, we are
in between two stronger shortwaves, which are within a broader
cyclonic flow. This weak flow regime means that nearly any thing
can trigger showers and even thunderstorms, and even at this hour
we have some showers over the minnesota arrowhead north of the
front. These are expected to slowly diminish over the next few
hours as convergence in the area gradually weakens as the front
sags farther south. An upper low to our west over eastern wyoming
this morning will gradually push east towards minnesota today and
tonight, gradually focusing precipitation chances on the inverted
trough currently extending from a low over SE colorado north
across the plains to south dakota. Tonight a weak wave ejecting
out of this upper low should push a band of showers storms north
across western minnesota, brushing our western forecast area
overnight. Precipitation chances continue across the western and
southern forecast area as the upper low slowly moves east across
the nebraska south dakota border on Monday. The surface low to our
west is going to interact with lake superior to produce east winds
for much of the area today and Monday, producing cool temperatures
in the mid 50s to mid 60s near lake superior and 70s and low 80s
elsewhere. This effect will be stronger today with the initially
stronger winds, but winds diminish somewhat for Monday and allow
warmer temperatures in general.

Long term (Monday night through Saturday)
issued at 351 am cdt Sun jun 24 2018
the main areas of focus for the long-term forecast continue to be a
few rounds of showers and thunderstorms for much of the northland,
with mostly above normal temperatures, especially for the mid- to
late-week period.

Monday night Tuesday morning finds a cut-off stacked upper-level low
embedded within a longwave upper-level ridge. The cut-off low will
be led by upper-level difluent flow, so large-scale deep lift will
be associated with this system, along with a 35 to 45 low-level jet
which will help to enhance warm air and moisture advection. Pwat
values are progged to rise to the 1.2 to 1.7" range, which is not
too anomalously high for this time of the year, but still would be
around 90% of climatology per the naefs mean pwat climatology
analysis. Instability looks to be lacking with this system, with
mucape values during this time frame ranging from a few hundred up
to 800 j kg, per the 24.00z GFS and NAM models. Effective bulk shear
looks to be rather low as well, so any showers and thunderstorms
that develop will have a difficult time becoming strong. Looks like
some heavy rainfall will be more likely with some of the
thunderstorms, particularly over northwest wisconsin where between
one quarter and up to one inch of rainfall will be possible Tuesday
morning. Winds will be easterly during the day Tuesday as well, so
we decreased temperatures slightly, particularly for areas along
lake superior, where it will be cooler than farther inland. Highs
Tuesday will range from upper 50s lakeside to the lower 70s inland.

Eventually, the cut-off low will advance eastward Tuesday night and
Wednesday morning. A northern stream wave could bring a small chance
for a shower or thunderstorm, mainly along the international border,
during the day Wednesday, but will quickly move out Wednesday
evening. The upper-level flow then becomes more zonal, leading to a
westerly flow regime from Wednesday through the rest of the week. At
the surface, the results will be winds from either the south or the
west, which is more favorable for warmer temperatures, even along
lake superior. High temperatures will warm into the lower 80s for
Thursday, with lower to middle 80s Friday. Heat index values for
Friday could reach into the middle to upper 80s over much of the
northland. Some spots may even reach into the 90s for heat indices
over our southern tier of counties. Southerly flow ahead of a
transient shortwave trough will lead to humid conditions as well,
with dew points possibly increasing to the middle to upper 60s
Friday, and again on Saturday, mainly for the southern half of our
forecast area both days.

Friday through Sunday will have a few rounds of precipitation once
again as a couple of transient shortwaves eject from a low-amplitude
longwave trough over the pacific northwest. While these waves will
be transient, they are progged to occur in succession during this
time frame, so there should be breaks in precipitation between each
wave. There is the potential for some strong storms during this time
frame as the GFS model is progging some larger values of mlcape, but
there is quite a bit of disagreement between the GFS and the ecmwf
and gem models regarding the amount of instability, so confidence
remains low for now.

Aviation (for the 12z tafs through 12z Monday morning)
issued at 642 am cdt Sun jun 24 2018
showers this morning over the arrowhead may affect khib this
morning before diminishing. Breezy east winds have swept some
stratus into kdlh this morning with ifr ceilings. Another area of
ifr stratus is affecting kinl. Both of these locations should
improve back toVFR sometime between 15z and 18z... Though I would
not be surprised to see a delay in this clearing trend with the
strength of the east winds at kdlh.VFR conditions are expected
after 18z. Breezy east winds to affect kdlh with gusts of
20-25kts through at least 02z before diminishing some. Lower
clouds to move back into the area after 06z, but should remainVFR
at the terminals until after 12z.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
