Synopsis
Periodic chances for light precipitation are expected through
the middle of next week with a series of crossing cold fronts.

Near term until 6 am Sunday morning
Low level moisture under a temperature inversion, along with
increasing clouds ahead of an approaching shortwave, should
maintain cloudy skies across the region tonight. Low chances for
light rain or snow are expected N of pit as moisture advects in
and pools ahead of an approaching weak cold front dropping s
across lake erie. Lows are expected to be a few degrees below
seasonal levels.

Short term 6 am Sunday morning through Monday
Light precipitation may be ongoing along north of the i80
corridor at the start of the short term period as low mid level
convergence increases along the aforementioned frontal boundary.

Upper level help will arrive with the progression of the h5 wave
pattern when an elongated vort lobe swings through the region
Sunday into Monday. This will make for an extended chance of
light precipitation through much of the period. Precipitation
type will be driven by surface low-level temperatures... So
expect to see mostly snow along north of i80, rain south of i70,
and an oscillating mix of the two in between. Regardless, qpf
through the short term period is expected to be light... So
generally little snow accumulation is expected.

Long term Monday night through Saturday
By Monday night, the upper level trough across the eastern conus
will deepen and a more robust shortwave will push through the
region. Moisture will be limited once again, but precipitation
will be possible along a cold front boundary as it moves across
the CWA Tuesday and post-boundary with some moisture from lake
erie. A mix of precipitation will be seen once again as low
level temperatures will be marginal for snow.

By late week, northeast CONUS troughing will relax with time,
and ridging is expected to arrive by late in the week. This
points to mainly dry weather from Wednesday night through
Friday, with a warming trend in temperatures.

Aviation 23z Saturday through Thursday
Low level moisture under a temperature inversion should maintain
MVFR CIGS for most PORTS N of I 70 tonight.VFR is expected S of
i 70 where clouds have eroded, though mid level clouds should
increase ahead of an approaching weak cold front. A brief return
toVFR is expected Sunday from pit swd as the inversion
weakens, with MVFR continuing n.

Moisture pooling ahead of an approaching weak cold front from
the n, and approaching low pressure from the sw, should return
MVFR for all PORTS through Sunday aftn, with CIGS decreasing to
ifr again N of pit. Light rain snow chances with the front low
were handled with a vcsh mention.

Outlook...

periodic restrictions are likely through Wed with a series of
crossing cold fronts.

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.
