Short term (through late Wednesday afternoon)
issued at 320 pm cdt Tue jun 27 2017
warmer temperatures are expected tonight and Wednesday as a surface
ridge centered over il and in shifts eastward and a south-southeast
surface wind increases due to a tightening surface pressure gradient
over our area. Surface dew points will also be gradually rising
leading to more humid conditions. Although warmer, lows tonight
will continue to be below normal for late june, especially across
southwest il. Highs on Wednesday will be close to seasonal normals.

Nocturnal convection is expected across ia into northwest mo tonight
associated with a strong southwesterly low level jet ahead of an
approaching shortwave. It appears that any showers storms should
remain north and west of our forecast area tonight. Weakening
overnight convection may move into parts of northeast mo Wednesday
morning, with additional development possible across northeast mo
and west central il along any outflow boundaries from late
night early morning convection as the atmosphere gets unstable in
this area during the afternoon.

Long term (Wednesday night through next Tuesday)
issued at 320 pm cdt Tue jun 27 2017
surface ridge continues to move east and will to be centered over
the southeast us by Wednesday night. A frontal boundary will be
located from southeast nebraska down to northeast kansas into the
southern plains. Ahead of the cold front,warm and moist air will
continue to stream northward ahead of the system. A look at model
soundings throughout the area show pw values of 1.5 to 2 inches in
the area during the Thursday through Saturday morning time frame.

Aloft the flow will be quite weak with a series of shortwaves moving
across the area through early next week. The combination of light
flow aloft, a slow moving front, and ample instability over the area
will allow for potential training of storms over the same areas.

There is potential for locally heavy rainfall amounts of over 4
inches in the northern tier counties with less amounts possible
further south. Wednesday night forecast CAPE values are in range of
2500 to 3000j kg with mid lapse rates around 7c km range. Thursday
and Friday both have forecast CAPE values in the range of 1500 to
2500j kg with lapse rates in the range of 7 to 8 c km. The bulk
shear also steadily increases in the Wednesday night through Friday
period from as little as 35 knots Wednesday night to near 60 knots
Friday. A limiting factor for Friday would be extent of cloudiness
over the area from previous convection. The primary threats for
Wednesday and Thursday will be damaging winds and large hail.

The front is forecast to move just south of the forecast area by
Saturday morning, then move up to the i-70 corridor by Sunday
morning. Areas south of i-70 could see an isolated shower or
thunderstorm while area north of i-70 will likely be dry. Sunday
should be dry for most areas until Sunday afternoon and evening as
the warm front moves north. Monday and Tuesday will have atleast a
chance for scattered showers and thunderstorms with the warm front
close to the missouri and iowa state line and a couple of
shortwaves coming across the region.

Aviation (for the 00z tafs through 00z Wednesday evening)
issued at 617 pm cdt Tue jun 27 2017
present indications are the terminals should experienceVFR flight
conditions through the forecast period. We will see some passing
high clouds tonight and then an increase in diurnal CU and
convective debris (mid high clouds) on Wednesday. We will need to
keep an eye on thunderstorm activity in the plains tonight and its
eastward progress into northwest mo and ia during the overnight
hours into Wednesday. Current thinking is this activity and any
new development on convective boundaries will remain across ia and
far northern mo on Wednesday, but it will bare close watching for
any southward development and potential impact at kuin. Gusty
southerly winds are expected from mid-late Wednesday morning into
the afternoon.

Specifics for kstl:
present indications are kstl should experienceVFR flight
conditions through the forecast period. We will see some passing
thin high clouds tonight and then an increase in diurnal CU and
convective debris clouds (mid high clouds) on Wednesday. Gusty
southerly winds are expected from mid-late Wednesday morning into
the afternoon.

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.
