Synopsis
Potent low pressure lifting from the lower mississippi valley to
the great lakes will bring accumulating snow and ice tonight,
before precipitation changes to heavy rain on Wednesday. High
pressure and dry air will build in Thursday behind the low.

Additional rainfall associated with the next area of low
pressure is expected Friday night through Saturday.

Near term until 6 am this morning
Surface low to develop over the central plains and deepen as it
ejects northeast into the upper ms vly Wednesday and into the
great lakes Wednesday night. Ahead of this system - strong
southerly low level jet of 50-55 kt to provide an axis of
isentropic lift overrunning a warm front that sets up over the
tn vly overnight.

Leading edge of pcpn was advancing across central ky and should
move into northern ky by midnight. Still a large spread in
snowfall and pcpn amounts among the model members. 12km nam
solution continues to be most aggressive with QPF north of
rain snow line and operational GFS is toward lower end of
snowfall fcst.

Have trended fcst solution closer to the 00z 3km NAM hrrr. This
is closer to the meso-scale models and above GFS but not as
aggressive as 12 km nam.

Expect a good burst of snow with strong lift over the area with
the best lift between 06z and 09z. Under good WAA - snow to
change to rain by 09z south of the ohio river and between 10-12z
up to i-70 and by 15z across the entire area.

Have adjusted snow up across the north and down across the far
south. Expect a 2 to 4 inch band generally along and north of
i-70 with 1 to 2 inches across SE indiana and southern ohio and
less than an inch south of the ohio river.

Have kept current headline winter weather advisories with these
adjusted amounts and timing.

Short term 6 am this morning through 6 pm Thursday
As precip changes to all rain from south to north in warm
advection that will allow highs in the 40s, wintry precip
hazards will improve by late morning, replaced by a flood threat
resulting from snowmelt combined with one to two inches of rain
falling on saturated soils. Since latest QPF seems to match
well with previous estimates, will keep flood watch as is across
far south and southeast counties. Will probably see some flood
advisories, and brush creek at west union in flood before
Wednesday is over. Thunder cannot be ruled out under elevated
instability associated with this potent system.

Rain will finally end Wednesday night as high pressure moves in
rapidly from the west. As runoff reaches streams, monitoring of
river points will continue with warnings possible. Expect above
normal lows in the 30s.

Long term Thursday night through Tuesday
Upper level ridging will develop into the region during the
latter part of the week. A negatively tilted short wave will
lift from the southern plains into the great lakes over the
weekend. In the wake of this system, flow will become more zonal
with another short wave moving into the region late in the
period.

Surface high pressure passing north and east of the forecast area
will keep shallow relatively cooler air in place for Thursday into
Friday, with temperatures near to slightly above normal. A warm
front will become more well defined with time over the tennessee
valley and lift north across the region during the latter parts of
Saturday. This will bring more wet weather but warmer temperatures.

Some weak instability may develop into the area Saturday night ahead
of a cold front that will sweep across the region which could result
in some storms as well more rain.

Cold air advection and a tight pressure gradient will result in
gusty winds on Sunday with the potential to approach advisory
levels. A few showers could persist as well as a secondary front
swings through. High pressure will bring a brief dry spell on Monday
with a chance of precipitation returning Tuesday as another area of
low pressure approaches. Temperatures will drop back closer to
normal for the early part of next week.

Aviation 06z Wednesday through Sunday
A mix of precipitation types is beginning at the TAF sites as of
this writing. At onset time, most of the precipitation should be
snow, with a mix of some sleet also occurring. This will bring
visibilities down into the ifr to lifr range, with ceilings also
dropping to ifr levels. Some accumulating snow is expected,
especially at kday kiln kcmh klck.

There will be a relatively quick transition in precipitation
types a little later in the morning. Snow will change to a mix
of snow, sleet, and freezing rain. Within an hour or two of
that, precipitation should change to rain. There should also be
an increase in visibilities as this occurs, though ceilings
should remain low through the day. Some periods of heavy rain
are also possible, with a very low chance (though worth
mentioning here) of thunder at kcvg kluk. East to southeast
winds during the day today may become briefly gusty to around 20
knots.

Tonight, rain will continue, though gradually decreasing in
intensity (and changing to drizzle) after 00z. There will also
be a period of llws, and later, some gusty winds (20-25 knots)
after a front moves through the area, shifting winds to the
southwest.

Outlook... Continuing MVFR ifr conditions with rain or drizzle
are possible at times through Thursday morning. MVFR conditions
are possible again on Saturday and Sunday, with gusty winds
expected on Sunday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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.
