Synopsis
Advancing low pressure will return rain to the region tonight.

Near term through Saturday
Shortwave ridging in advance of a midwestern shortwave will
suppress rain over the upper ohio region early this evening.

The reprieve looks to be brief though as the midwest disturbance
is going to dig rapidly eastward and begin to spread showers and
thunderstorms over the immediate area as the night deepens.

All guidance is indicating rain as far north of the I 80
corridor with the mid level trough axis, although the sfc low
track-prog is along or just south of the I 70 corridor.

The late aftn update thus features adjusted precip probs for
that evenuality. Better thunderstorm chances with a weakening
mcs are anticipated for areas south of pittsburgh as per expectations
of surface warm front progress on the warm surge and resulting
instability profiles; nevertheless, a scattered mention was
included up to I 80 given elevated expectations on the northern
flank of the sfc low.

Progression and fading instability should keep this passing
system from being problematic in terms of severe storms and
flooding.

Improvement is anticipated Saturday as shortwave ridging ensues
in the wake of the night morning rain. Have thus reduced precip
probs more rapidly than previously indicated. Residual cloud
cover should prevent strong temperature recovery despite rising
heights on Saturday. Overall, readings a few degrees above the
averages can be anticipated for the period.

Short term Saturday night through Monday
A shortwave crossing the upper midwest and great lakes through
Sunday is forecast to increase rain chances again on Sunday with
the warm surge on the van of the system. The associated cold
front should support further convection into the night, with
improvement on Monday as high pressure rapidly slides across the
area. Temperatures generally will remain near or just above climatology.

Long term Monday night through Friday
Broad upper troughing will develop behind the Sunday cold front,
with that pattern lingering through most of next week. Shortwaves
rotating through the trough will provide occasional chances for
mainly scattered showers. Temperatures will generally remain
near or just below average values.

Aviation 21z Friday through Wednesday
Condition deterioration is expected tonight as crossing low
pressure spreads showers and thunderstorms across upper ohio
valley terminals. Expect a condition downgrade to eventual ifr,
ceilings of which are likely to linger through much of Saturday
morning before shortwave ridging returnsVFR to area ports.

Outlook
Rain and restriction potential will return with Sunday low pressure.

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.
