Short term (this evening through Tuesday)
issued at 408 pm cdt Mon mar 18 2019
relatively quiet conditions were found across the northland this
afternoon. Diurnal CU developed over the arrowhead and much of
northwest wisconsin. Moisture depth appears limited and expect
there are few, if any, snowflakes or raindrops reaching the
ground. Cloud cover will gradually increase from the northwest
tonight as a shortwave trough moves through the area. Models have
been struggling with the sky cover all day and I think the
consensus blend is too pessimistic. In collaboration with
neighboring offices, i’ve decreased sky cover below guidance,
but not by much. Temperatures were able to cool considerably last
night, even with the presence of thin overcast. Have lowered temps
toward the cooler side of the bias-corrected guidance tonight
with lows in the low teens to low 20s.

Tuesday looks dry at this time as there will be a brief period of
ridging before the next shortwave trough arrives Tuesday evening.

There are concerns about dry air below cloud layer with the
second trough. Have lowered pops in consideration of the dry air
near the surface. Have brought slight chance pops southeastward
from our northern zones into the arrowhead and eventually
northwest wisconsin Tuesday night. Portions of central minnesota
should remain dry as the best forcing will be located farther
east. Highs on Tuesday will reach the middle 40s in northwest
wisconsin and the upper 30s and low 40s in minnesota. Lows Tuesday
night will be in the low to upper 20s.

Long term (Tuesday night through Monday)
issued at 408 pm cdt Mon mar 18 2019
Wednesday morning we may have some lingering snow rain showers in
the morning as the shortwave from Tuesday night finishes moving
through the area. Low level dry air moving in behind this wave
should keep any diurnally driven afternoon cumulus from producing
any showers, but cloud cover should stay relatively high as a
result.

Wednesday night through Saturday will be quiet, with a a gradual
warming trend. On Wednesday night, a shortwave will drop through
the northwest flow aloft, but should not affect the forecast area
with more than some cloud cover, as the most potent part of the
shortwave stays east of the forecast area. Behind that wave,
ridging at both the surface and aloft builds in over the forecast
area for Thursday through Saturday, and while a weak, fast moving
shortwave dives through the flow across the area Thursday night,
it also looks too far east to bring showers to the area.

Sunday and Monday there are some significant differences in the
forecast between the models. In the Wednesday-Thursday time range
an upper low moves onto the southwest conus, and since at this
point it is already cut off from the northern stream flow, it
slowly meanders east across the rockies Friday and Saturday before
shifting far enough east to affect the central CONUS late on the
weekend and early next week. The models differ in how far south
the upper features slide, and how much ridging stays in place over
the forecast area. This results in the farther north GFS bringing
a two day period of rain chances to the forecast area, with the
more southerly ECMWF and cmc keeping us dry. For now have left the
consensus chance pops in the forecast, and we will have to see
how the trends evolve before pinning this event down. Personally i
suspect the GFS is far too wet, but we should get at least a
small chance of precipitation sometime in that time range.

Aviation (for the 06z tafs through 06z Tuesday night)
issued at 1237 am cdt Tue mar 19 2019
vfr conditions will prevail for most of the night before MVFR
ceilings move in from west to east across northeast minnesota on
Tuesday, into northwest wisconsin on Tuesday night. Light rain snow
showers are possible late Tuesday into Tuesday night at most sites,
but visibility is not expected to be diminished much due to the
light intensity of the precipitation. Winds less than 5 knots out
of the southwest overnight, increasing out of the west-southwest at
5 to 10 knots on Tuesday into Tuesday night.

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.
