Synopsis
Issued at 453 am edt Thu mar 30 2017
showers and thunderstorms are expected in the area today and
tonight as a low pressure system approaches from the southern
plains. There is a risk of severe storms, especially across
southern portions of the area this afternoon and this evening.

Showers will taper off from west to east Friday as the low
departs. High pressure will build into the midwest Saturday
providing fair weather.

Short term (today through Friday)
issued at 453 am edt Thu mar 30 2017
a vigorous upper level low was centered over eastern kansas early
this morning. This system will move east and track north of the
ohio valley Friday. Several factors appear to be coming together
for the potential for severe storms over the forecast area today
and early tonight. A warm front will move north today and should
be close to highway 30 by late afternoon. A cool east flow north
of the front off lake erie will accentuate the front. Increasing
instability combined with increasing low level shear will enhance
the chances for strong to severe storms including large hail,
damaging winds and isolated tornadoes along and south of the
front. The best chances for severe storms is from mid afternoon
through this evening. Precipitable water values are still expected
to approach climatological maxes of 1.25 for this time of year.

Rainfall amounts by the time rain ends Friday should range
between 0.75 inches over northwest ohio to 1.25 inches over
northwest indiana. Lingering rain will diminish Friday as the low
moves east and high pressure builds across the area.

Long term (Friday night through Wednesday)
issued at 453 am edt Thu mar 30 2017
two more rounds of rain are on the horizon as more upper level
systems move across the area next week. Rain is expected to
develop by late Sunday and continue into Monday with the arrival
of next system. After a break Tuesday, more rain is likely
Wednesday. Thermal profiles favor all rain.

Aviation (for the 12z tafs through 12z Friday morning)
issued at 615 am edt Thu mar 30 2017
low pressure over mo expected to lift slowly NE into NW oh by 12z
fri. Initial cluster of showers and tstms in low level theta-e
advection regime were lifting NE of NRN in ATTM but broad isent
lift and upr level divergence along with now moist airmass in
place should keep at least sct shra/ts going through the day and
into this eve. Brief MVFR/ifr conditions likely with heavier
shra/ts and there is also a risk of hail and gusty winds accompanying
the storms, mainly this aftn/eve. Otrws, flight conditions
expected to grdly lower to MVFR/ifr at sbn today while fwa remains
predominantlyVFR as the low tracks NE between the two terminals.

As the low passes tonight the lower flight conditions should
advect SE into fwa.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
