6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Short term (this evening through Friday)
issued at 212 pm cst Thu nov 23 2017
the main concern is where and how much precipitation there will be
across the area Friday afternoon. The main short wave trough will
swing across the upper midwest during the afternoon with the 23.12z
nam showing this producing a band of moderate PV advection in the
500-300 mb layer. As the cold front moves in with the short wave
trough, there should be a band of weak to moderate frontogenesis in
the 1000-500 mb layer. Decent up glide should occur as well, with 2
to 5 ubar S expected on the 290k isentropic surface right along and
a little behind the surface front. With this good forcing, the main
question is just where will there be enough moisture to allow
saturation to occur. The NAM would suggest the best chances for
saturation and precipitation would be well to the north of the area
across northern minnesota and over lake superior. The 23.12z GFS is
a little farther south but still mainly across central minnesota
into northern wisconsin, or generally north of interstate 94. With
these signals, have trended the area of precipitation chances a bit
farther north with the highest chances across taylor county. For
now, have kept the chances no higher than 50 percent, but could see
the need to possibly have these bumped up some if the forcing
signals remain consistent. Temperatures ahead of the front will warm
well into the 40s and 50s, so the precipitation Friday will be all
rain.

Long term (Friday night through Thursday)
issued at 212 pm cst Thu nov 23 2017
the end of november is shaping up to be very quiet weather-wise
across the region. Surface high pressure will drift across the
region through the weekend providing dry conditions with plenty of
sunshine save for some patches of high clouds at times. Even
behind the cold front, temps will remain seasonable, with highs
near or above 40 in most locales on Saturday, except for north
central wisconsin. 925 mb temps do warm several degrees from
Saturday to Sunday as the surface high passes to the southeast,
supporting warmer highs well into the 40s, with even some 50s
possible.

Heading into the coming work week, upper ridging will spread over
the area on Monday ahead of an upper level trough approaching from
the rockies. Some mid high clouds may move across the area, but with
a very mild airmass (925 mb temps of 7-11c), well above average
highs back near or above 50 appear likely in most areas.

There are some model differences persisting among the various
model solutions with the upper trough passage on Tuesday and
subsequent evolution of the upper air pattern. 12z models suggest
a stronger shortwave will pass well north, while another wave
ejecting into the southern plains may eventually close off to the
south over the course of the week. As a result, much of the deep
forcing remains north and south of the area, so will maintain a
dry forecast into mid-week. Temps will cool down behind a cold
frontal passage Monday night into Tuesday, but temps are expected
to remain at least near seasonal norms through the next week.

Aviation (for the 00z tafs through 00z Friday evening)
issued at 534 pm cst Thu nov 23 2017
vfr conditions expected for much of the region the next 24 hours,
with some passing mid and high clouds, possibly a little thicker
at times. Winds will increase through the night from a southerly
direction, though the more sheltered location of lse will allow
for low level wind shear to develop, mainly after midnight with a
strong low level jet ramping up just above a shallow inversion. A
cold front is still expected to arrive later Friday afternoon,
shifting winds west northwest with a few gusts to around 25 knots
possible at rst, though with little chance for significant
precipitation as the deepest moisture skirts by to the north of
the terminal sites.

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.
