Synopsis
Hot and humid today. Cold front tonight into Friday. Generally
drier afterwards until Tuesday. Another cold front by mid week.

Near term through tonight
As of 930 am Thursday... Ran an update to decrease cloud cover
this morning and lowered pop until later this afternoon. Current
guidance is showing a weak prefrontal trough that will push
through early this afternoon into the early evening hours.

Should at least see scattered showers and thunderstorms pop up
with this feature and with pwats close to 2", high freezing
level, and long skinny CAPE profiles these showers and storms
will be efficient rainfall producers. Later tonight the cold
front will enter the ohio valley between 8 and 10 pm and push
across the region. The best shear and dynamics with this front
is still going to be off to our north, but if the front can
arrive early enough and can tap into the better instability,
then there is some concern that some storms may contain strong
gusty winds across our far northwestern zones.

As of 645 am Thursday...

clouds will be on the increase early this morning as a surface
and upper level low move through the northern plains. The first
impulse associated with the upper air feature should kick off
showers and thunderstorms across the tri-state mid morning,
with activity drifting NE through the afternoon. Decent
instability across the area with the hot and humid air in place
-- MLCAPE should be in the 1000-1500j kg range. The cape
profile is rather skinny and shear of 20-30kts is fairly
marginal for strong to severe storms. However, with precipitable
water values topping 2 inches, heavy rain is likely in mature
convection. Flash flood guidance is generally 1.5-2.5 inches
across the forecast area. The most likely area of heavy rain
today -- across the ohio river valley and western lowlands of wv
-- corresponds to the higher FFG so not planning a flash flood
watch. Still... Cannot rule out isolated issues with repetitive
storms.

Tonight, we should have a line of showers and thunderstorms move
from west to east ahead of a cold front. Instability drops off
quickly 00z Friday, but precipitable water remains on the high
side... So again strong to severe storms not expected but heavy
rainfall is likely.

Short term Friday through Sunday night
As of 310 am Thursday...

what remains of a cold front crosses the CWA Friday for scattered
showers.

A weak upper level wave brushes the northern CWA over the
weekend though high pressure will likely keep the rest of the
area rain free and warm.

High pressure continues Sunday for dry weather area wide.

Long term Monday through Wednesday
As of 310 am Thursday...

high pressure continues Monday for dry weather area wide. Moisture
will increase Tuesday and Wednesday ahead of the next
approaching cold front. The cold front crosses Wednesday into
Thursday.

Aviation 14z Thursday through Monday
As of 645 am Thursday...

any lingering fog should dissipate quickly over the next couple
hours. Clouds will be on the increase this morning.

Several areas of showers and thunderstorms are expected today
and tonight. Brief ifr will be possible in any developed shower
or storm, but to early to pinpoint any timing on that so went
with more general MVFR for now.

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

forecast confidence: medium on overall trends, low on small
scale specifics.

Alternate scenarios: will likely need amendments for ifr in
storms later today and tonight.

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.
