Short term (today through Tuesday)
issued at 354 am cdt Mon aug 19 2019
no significant changes to the previous forecast, other than
increasing pops slightly for Monday night across the southwest.

Today will be sunny and a bit warmer as the surface high pressure
shifts eastward and allows southerly return flow on the back side to
advect warmer air and higher dewpoints across the region. This can
be seen but precipitable water values of 1.5 inches across western
minnesota Monday evening, while western wisconsin remains at less
than an inch.

The low level moisture together with steeper mid-level lapse rates
will lead to MUCAPE values in excess of 2000 j kg Monday night along
the minnesota dakota border. Meanwhile a weak shortwave trough,
which as of Sunday night was located over northern california, will
move eastward and provide the lifting mechanism for scattered
thunderstorms Monday night. Although this is subtle feature, there
is a fairly impressive response in h850 theta_e advection, so did
increase pops a bit higher than guidance in southwest minnesota.

On Tuesday a cold front will move through the region and provide
additional chances for showers and thunderstorms, but at this point
it looks like most locations will have just increased cloudiness,
and perhaps some light rainfall.

Long term (Tuesday night through Sunday)
issued at 354 am cdt Mon aug 19 2019
the middle of the week will start out dry with a taste of fall in
the air as a cold front moves through the region and brings highs in
the 70s, with lows in the 50s for Wednesday and Thursday. The next
shortwave trough approaches Thursday night into Friday, and this
will bring in warmer air and be the focus for another chance for
thunderstorms. Looking ahead, warmer temperatures and increased
humidity should last through next weekend.

Cold air advection will continue Tuesday night as surface high
pressure builds across the region. Wednesday will a great day to be
outside, with light northerly winds, low humidity, and highs in the
mid to upper 70s. The same holds true for the start of Thursday as
well.

Throughout the day on Thursday, surface high pressure will again
track eastward and southerly winds will develop on the back side
which will bring a warmer and more humid air mass across western
minnesota. This warm and humid air mass will overspread the rest of
minnesota and wisconsin over the weekend. Meanwhile, both the gfs
and ECMWF are in good agreement with a more zonal upper level jet
developing across the northern conus. This will increase the deep
layer shear profile. If convection does manage to develop this
weekend, it could be somewhat organized. Lack of instability is a
limiting factor. It is still way to early to latch on to any one
forecast, but the big picture perspective does merit this as
something worth watching.

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.
