Marine Weather and Tides
Cuba, MO

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Short term (through late tonight)
issued at 316 am cdt Wed may 23 2018
a surface ridge extended from a surface high over lake michigan
southwestward across across the CWA into south central missouri
early this morning. The only surface observation reporting fog at
this hour was farmington, and surface observations indicate that
dewpoint depressions are close to zero in some areas. Will continue
to monitor for fog development through sunrise, particularly over
southeast missouri and in river valleys where fog was the thickest
yesterday morning.

Still expect a mostly sunny sky across the area today as an upper
level ridge remains over the midwest. Have added a slight chance of
thunderstorms over a small part of central missouri this afternoon.

The hrrr and NAM forecast soundings at kcou are showing the
atmosphere becoming uncapped with about 1000-1500 j kg of cape. Any
storms that do develop will diminish with loss of daytime heating,
so expect tonight to be dry.

Expect temperatures to be above normal again today, and went at or
just above the warmest MOS guidance for highs. Lows tonight will
once again only fall into the 60s.

Long term (Thursday through Tuesday)
issued at 316 am cdt Wed may 23 2018
high pressure centered over the great lakes and ohio valley on
Thursday morning will drift east off the atlantic coast by Friday
afternoon. The mid upper level ridge over the midwest will also be
flattening out and moving east during this time. This will allow a
trof to dip into the mississippi valley which will help draw a gulf
low pressure system up into the lower mississippi valley this
weekend. Southerly flow on the western side of the retreating ridge
will bring increasing increasing instability to the mid mississippi
valley on Thursday afternoon. All model guidance is now printing
out light QPF Thursday afternoon over central missouri. This is
further east than yesterday's model runs. It doesn't look like
there are any synoptic boundaries for convection to focus on, so
think only isolated showers storms are possible. The trend of pops
moving further east continues on Friday with chance slight chance
pops covering most of the area Friday afternoon. The convection on
Thursday and Friday look to be primarily diurnally driven... Though
the GFS does develop a weak nocturnal low level jet on Friday night.

Not entirely sure the low level jet and subsequent nocturnal
convection isn't caused by upstream grid-scale convective feedback
so have only kept chance slight chance pops going for Friday night
rather than more widespread precip as the GFS suggests.

Medium range guidance handles the details of the aforementioned gulf
low a bit differently this weekend into early next week... Though the
general idea is essentially the same. The low drifts up into the
southern u.S. Saturday through Tuesday spreading precipitation up
the mississippi valley toward the midwest. The ECMWF moves the low
up over louisiana, directly over the lower mississippi valley through
Tuesday, while the GFS is further east and faster, moving the low up
over the florida panhandle through georgia and up into
tennessee northern alabama by Tuesday afternoon. Both models
develop a ridge north of the low in a rex-block configuration
between Monday and Tuesday as well. The GFS shows much more
widespread precip than the ec as is typical. One way or another,
the chance for showers and storms will be increasing late this
weekend and early next week as the low brings deep gulf moisture up
into the mid mississippi valley. Little change in temperatures
through the period with highs in the mid to upper 80s and lows in
the mid 60s to near 70.

issued at 1030 pm cdt Tue may 22 2018
vfr conditions, dry weather, and light surface winds will prevail
at the TAF sites thru the valid period. Some potential for fog at
river valley sites (cps, sus) but current indications are vsbys
should stay out of ifr. Otherwise, variable winds will become E to
se by Wednesday daytime.

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.
