Short term (this evening through Sunday)

this afternoon, the upper midwest was caught between an anomalous
upper low across the great lakes-ohio valley, and an upper ridge
over the high plains of montana and western north dakota. Deep
layer moisture has been abundant in the eastern 1 4 of mpx
forecast area of west central wisconsin due to the persistent
wrap around of the moisture associated with the upper low. Mid
level lapse rates are weak in this area of west central wisconsin,
but at least enough to generate a few diurnally driven showers or
storms through the early evening. Elsewhere over the upper
midwest, very dry mid levels will keep this area dry through
The persistent north northeast flow in the boundary layer will also
lead to an increase in boundary layer moisture across wisconsin
later tonight. This may lead to low stratus fog building across the
area toward sunrise. Sunday will mostly sunny and dry with an
increasing southeast wind in western minnesota in advance of a cold
front moving across the dakotas.
Long term (Sunday night through Saturday)

the pattern will be characterized by an upper high in the
southwest that slowly retrogrades, leading to a broad upper low
and trough across central and eastern canada and into the u.S. By
mid and late week.
Aforementioned ridge over the high plains will shift eastward, and
it should extend across minnesota tomorrow evening. An upper low
in western canada will follow, bringing broad ascent later Sunday
night and Monday in the wake of the ridge. Moisture will be
abundant, evidenced by the storms developing at this time from
saskatchewan into wyoming and colorado. Thus have maintained the
chance of storms late Sunday night and Monday across the area.
Models are in decent agreement with moving the trough past mn wi
later Monday, so Monday night and Tuesday should be dry.
As the canadian upper low heads for the great lakes region
Thursday, the next trough will approach Tuesday evening. Cooler
air will begin filtering in with northwest flow. Temps aloft drop
quite a bit, and this is a pattern typical of scattered showers|
with a few afternoon evening thunderstorms as well. Highs
Thursday look to be the coolest of the upcoming period, when the
upper low is the closest to mn wi. But even as it moves away into
eastern canada Friday, there should still be some northwest flow
and cool enough temps aloft to help promote more showers on Friday
afternoon evening. And again on Saturday. Certainly a pre-fall

main change from 00z tafs is stratus in wi is not looking to make
it as far west in wi, which means eau will remain in the clear. It
will beVFR through the night, with only a small threat of br fg
at axn stc rwf, but potential is too low to include in the tafs.
With high pressure passing off to the north Sunday, we'll have
light east winds and a few-sct CU field between 3k and 5k feet.
During the afternoon, thunderstorms will develop along a cold
front in nodak and will be heading toward axn by the end of the
taf period. A few of the cams show TS reaching axn as early as 3z,
but that thunder will be on a decreasing trend, so will wait until
confidence increases on TS evolution into mn before brining any
mention in to the taf.
Kmsp... At the end of the period, a few of the cams are indicating
showers may be in the area, with the hrrr being the most
aggressive with showing showers in the area as early as 8z. This
looks overdone when looking at forcing instability forecasts, so
have kept msp dry and would be surprised if msp saw anything at
all with this front coming through on Monday.
Outlook for kmsp
mon...VFR. Slight chc -tsra. Wind vrbl bcmg NW 5-10 kts.
Tue...VFR. Wind W 5 kts.
Wed...VFR. Slight chc -tsra. Wind W bcmg NW 10g20 kts.

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.
