Moderate to heavy rain exits the region overnight from west to
east. Brief high pressure on Thursday before next system arrives
from the south on Friday and persists through Saturday night.

Near term through Thursday
As of 130 pm Wednesday...

still have flood headlines in affect this afternoon with more
moderate to heavy rain pushing in. Winter storm warning has
been dropped everywhere except for pocahontas and eastern
randolph county. Temperatures remain in the upper 20s to low 30s
and freezing rain should continue into this evening until the
cold air scours out. Likely an end time of 0z will still be good
for the warning as cad is is starting to break down this

Currently have a stationary front draped from SW to NE across
central west virginia. We have one more shortwave that moves in
from the SW later this afternoon and this evening with a weak
surface low riding up the front. This should be the last of the
of the heavy rainfall and as the wave low exits to the ne, the
front finally pushes eastward. Rainfall will come to an end from
west to east late tonight. High pressure builds in Thursday
morning and this will bring a much needed dry day with
temperatures climbing above normal.

Short term Thursday night through Saturday night
As of 230 pm Wednesday...

a stalled frontal boundary will be positioned south of the region
Thursday night through Friday morning while waves of energy rotate
around the periphery of a subtropical ridge in the southwestern
atlantic. As this energy interacts with the stalled frontal
boundary, precipitation chances will increase by Friday morning,
mainly across southern areas of the cwa. However, it's possible that
slight pops could extend as far north as the northeast mountains and
if precip can reach this far north before surface temps rise above
freezing by mid morning, a brief period of freezing rain sleet in
the northern and central mountains could occur. Little to no ice
accumulation is expected at this point, but this could make roads
slick until surface temps warm above freezing.

The boundary will gradually lift northward as a warm front through
Saturday morning as a mid level trough and surface cyclone move
across the central conus. Thus, precipitation will increase in
coverage from south to north Friday evening through Saturday as the
aforementioned warm front pulls to the north. The majority of this
precipitation should occur in the form of rain, but some light snow
could occur Saturday morning in the mountains before transitioning
to rain. It appears that another soaking rain is likely with this
system with models indicating that QPF values will be in the 1-1.50"
range. Given Wednesday's heavy rain event, most of the region will
still be trying to recover and additional rainfall which could bring
further hydro concerns to the area. In addition, models are
indicating that there could be just enough elevated instability
across western areas to support the mention of some embedded
thunderstorms by Saturday evening ahead of a cold front and upper
trough advancing from the west. While strong dynamics will be
present, CAPE values will be low, with around 200 j kg possible in
our western counties. For now, have left the mention of thunder just
outside of our area, but there is at least some risk of elevated
thunderstorms Saturday night in northeast ky and southeast oh.

Precipitation will then decrease in coverage from west to east
towards the end of the short term period.

Long term Sunday through Wednesday
As of 150 pm Wednesday...

cooler air will gradually move in behind a cold front Sunday and
Sunday night. There is some debate among the models if the air
will get cold enough for some upslope snow Sunday night.

A high pressure system will then move over on Monday.

Another system will effect the region for Tuesday night or
Wednesday, but models disagree considerably with this system.

Therefore confidence is low.

Aviation 20z Wednesday through Monday
As of 1250 pm Wednesday...

heavy rain will continue for much of the region through this
evening. Mvf to ifr restrictions will be possible in the heavier
rain showers. Strong low level winds will produce low level wind
shear conditions with flow increasing to near 50 knots at 2000
feet agl. Stationary front will slide east of the region during
the pre-dawn hours on Thursday and will bring an end to the
rain. Conditions should improve from west to east through the

Forecast confidence and alternate scenarios through 18z Thursday...

forecast confidence: medium.

Alternate scenarios: visibility conditions under moderate rain
may vary. Ceilings heights could vary under heavier showers as

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.

These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
