Short term (this evening through Tuesday)
issued at 307 pm cdt Mon apr 23 2018
april showers (rain not snow) are on the way! The next measurable
precipitation arrives tonight into Tuesday as a shortwave currently
over the northern plains translates southeast into the dakotas.

Latest model runs place the highest QPF (0.10"-0.60") along and west
of the i-29 corridor. Thermal profiles suggest a deep and rich bl
moisture along and west of the james river, starting in the
nighttime and continuing through the day on Tuesday. With that
said, better chances fall across southeast sd, likely along the
missouri river valley; albeit areas along and east of i-29 could
see sprinkles very light rain. Most of the instability remains
farther south of the forecast area, therefore only rain chances
are anticipated.

Scattered showers will begin to move across the mo river after 07z
Tuesday, then spreading east-southeast across southeast south dakota
throughout the day, before tapering off early in the evening hours.

With increasing clouds and showers, Tuesday will mainly in the 50s
to mid 60s over northwest iowa.

Long term (Tuesday night through Monday)
issued at 307 pm cdt Mon apr 23 2018
a surface ridge settles in by Wednesday, leaving the region dry
with plenty of sunshine and mild temperatures. Highs will reach
the upper 50s and 60s.

A weak disturbance and associated cold front will move southeast
from north dakota into iowa by Thursday. Looks to be a fast-moving
system, therefore not much is expected in terms of precipitation. As
for now, better chances for light rain looks to be along and east of
a line from sux to worthington to marshall which is where better
omega lifting and saturated layer persist. Low-level layers should
remain saturated so mostly cloudy conditions are still expected
through mid-afternoon, bringing more sunshine by late afternoon and
evening.

For the remainder of the extended, temperatures will be the main
feature. Building heights move in behind the frontal boundary,
leaving the forecast area mostly dry. With southerly surface winds
prevailing through the weekend, near to above normal temperatures
are expected with highs reaching the 70s. Model guidance diverges
in temperatures, bringing cooler temperatures; therefore have
raised temperatures from Friday to Monday by blending superblend
and consraw to produce highs in the 60s and 70s.

Aviation (for the 00z tafs through 00z Tuesday evening)
issued at 614 pm cdt Mon apr 23 2018
mid and high level clouds will be on the increase from west to
east through the overnight hours ahead of our next incoming
system. Light rain showers are possible mainly along and west of
the james river valley by after 09z Tuesday. Low endVFR to MVFR
ceilings are expected over this same area with khon being the
most likely to be impacted by these conditions. Kfsd ksux are
expected to remainVFR though the period.

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.
