Synopsis
A warm front lifts through today, followed by a cold front
tonight into Friday. High pressure Sunday. Next system Monday
or Tuesday.

Near term /through tonight/
As of 630 am Thursday...

high clouds will be on the increase early today as a surface low
and closed 500mb low cross the central plains. This will lift a
warm front through, with isolated to scattered showers and
thunderstorms possible along the ohio river and into
north-central wv. With SE flow at the surface, think precip
will have a hard time moving into the typical downslope zone
along i-79 from charleston to clarksburg. However the SE flow
could drive some light rain along the eastern slopes and
appalachian ridge.

Precip will rapidly increase tonight as the surface low crosses
northern in with a cold front pushing in from the west. This
will likely be the remnants of the strong to severe
thunderstorms expected in the lower ohio river valley today. It
will be coming through overnight, a poor time for sustained
strong convection. However, should a good cold pool driven
convective complex already be ongoing, there is enough cape
(200-400j/kg) and shear (40-50kts) to keep a somewhat organized
line going as it moves in from the west with a potential for
damaging winds and some hail.

Pwat values of 1.0-1.3" indicate the potential of heavy rain.

Basin averages should be in the 0.25-0.5" range, but of course
there could be locally higher amounts which could approach an
inch. With current 3 hour flash flood guidance of around 1.5-2"
we should be able to avoid any significant water issues.

Short term /Friday through Sunday night/
As of 400 am Thursday...

a strong system exits the area Friday though not before
squeezing out at least a 1/2" of QPE area wide. A few wrap
around showers linger into Saturday. Otherwise high pressure
builds through Sunday night.

Long term /Monday through Wednesday/
As of 400 am Thursday...

the next system approaches Monday and crosses late Monday night
into Tuesday. High pressure builds again Wednesday. The active
weather pattern continues with no end in sight. A little
hesitant to add details as run to run consistency is poor on
low pressure tracks, but good on general pattern recognition.

Aviation /12z Thursday through Monday/
As of 630 am Thursday...

vfr expected today, with clouds on the increase. An isolated to
scattered t-shower is possible along the ohio river and across
the eastern slopes, which could lead to restrictions but
confidence not high enough to mention at any TAF site. More
widespread rain will begin moving in late tonight with MVFR to
ifr visibilities likely. Wind will generally be SE to S through
the TAF period.

Forecast confidence and alternate scenarios through 12z Friday...

forecast confidence: high.

Alternate scenarios: could get some MVFR to ifr in t-showers
today. Timing of showers and storms tonight may vary.

Experimental table of flight category objectively shows consistency
of WFO forecast to available model information:
h = high: TAF consistent with all models or all but one model.

M = medium: TAF has varying level of consistency with models.

L = low: TAF inconsistent with all models or all but one model.

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.
