Synopsis
Weekend warm temperature will be marred by increasing rain
chances on Sunday.

Near term /until 6 pm this evening/
Cloud cover and ongoing warm advection supported a very warm
night with temperatures 25 to 30 degrees above the averages.

Morning hourly trends were tweaked toward the much warmer nam
and high res models in conjunction with current observations.

Otherwise, shortwave ridging on the van of a cutoff plains low
suppresses will suppress widespread precip for most of the
region. The exception may be the I 80 corridor where the
encroachment of a front in conjunction with a northern stream
shortwave may support some isolated, to scattered showers today.

With the upper ohio firmly entrenched under the ridge/warm sector,
warm high-temperatures can again be expected with readings
about 20 degrees above the averages forecast, with only minor
moderation projected along the I 80 counties as the
aforementioned front sags toward/across that area.

Short term /6 pm this evening through Monday/
As the cutoff low over the plains digs eastward this weekend,
shortwave ridging will suppress widespread rain and maintain
warmth for the immediate area. Moist flow and that systems
occluded front will degrade that inhibition on Sunday and pops
will be on the increase, albeit with questionable timing given
model discrepancy in handling the cutoff low.

For now, have continued the ongoing categorical pops, but have
adjusted timing and the mention of thunder given instability
projections. Renewed shortwave ridging in the wake of that
weakening system, and in advance of another midwestern shortwave
in timed to provide a break in precip for Monday.

Long term /Monday night through Friday/
Zonal and split flow is forecast to initially maintain above
average temperature for the remainder of the week, although a
midweek front is expected to drop them closer to the averages.

The next, best chance for precip is expected with that front
and with another, albeit filling cutoff low emerging from the
plains by the weekend. Tweaked superblend was used in long-term
forecast construction.

Aviation /07z Saturday through Wednesday/
Vfr conditions are expected this morning under shortwave
ridging. Moisture pooling along a slow swd moving cold front
should result in MVFR ceilings over NW pa as midday approaches.

Ceilings should lower elsewhere as the front moves further
south, thoughVFR levels should be maintained.

Outlook...

widespread restrictions are likely later on Sunday with crossing
low pressure, and again with a Monday night cold front.

Pbz watches/warnings/advisories
Md... None.

Oh... None.

Pa... None.

Wv... None.

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.
