906 pm est Sat feb 24 2018

Warm front pushes north through the area tonight. Cold front
sweeps across Sunday. High pressure brings dry air by Sunday
and start to work week. Next low pressure system mid week.

Near term through Sunday
As of 350 pm Saturday...

sent an update to remove most pops across the lowlands in a lull
suggested by the hrrr and latest radar images. Another but more
widespread area of rainfall is evident moving northeast across
central ky into southern oh. This activity is expected to reach
southeast oh by 00z Sunday. Rest of forecast remains on track.

As of 120 pm Saturday...

warm advection rainfall did finally pick up in intensity, causing
some small stream and poor drainage flooding. This rain will move
out of the area by this evening, but more rounds are expected later

As of 1045 am Saturday...

rain overnight did not amount to much, and neither is warm
advection rain today so far. Mainstem ohio river forecasts
reflect lower crests, as a result. The weather forecast is
otherwise largely on track.

As of 300 am Saturday...

a frontal boundary will remain across the area today as a wave
brings an area of showers. Much of the area should then go into
a lull later this afternoon and early this evening as the front
pushes north of the area. Showers will return later tonight as a
cold front approaches from the west. Models continue to show the
highest rainfall amounts over southeastern ohio and northern
west virginia, although amounts are toned down compared to
previous runs. Will continue the flood watch as the ground is
saturated and streams and rivers continue to run high.

Short term Sunday night through Tuesday
As of 140 pm Saturday...

wave developing along the front on the south and east side of
the mountains could push some light rain back into the southwest
virginia and far southern west virginia counties Sunday
night early Monday morning, but will quickly be forced back out
of the southern zones of the cwa. Otherwise, the period is
dominated by high pressure and a much welcomed drying out
period. Dominant upper level ridging over the gulf of mexico and
florida keeps the area milder than normal for this time of year
with above 0c 850mb temperatures.

Long term Tuesday night through Saturday
As of 140 pm Saturday...

more rain arrives for the middle to end of the week from a fast
moving panhandle low pressure system. Will need to watch the
rainfall amounts combined with the ability for the
rivers creeks streams surface to recover from a very wet second
half of february, and if the system will set up over the ohio
valley yet again.

Aviation 00z Sunday through Thursday
As of 700 pm Saturday...

a warm front pushes north across the oh and WV tonight. Rain
showers will spread slowly from west to east through the
overnight hours. Widespread MVFR ifr conditions expected
especially along moderate to heavy rain.

Cloudiness and southerly boundary layer winds around 15 to 20
knots will keep radiational fog from development. However, warm
moisture advection could produce periods of dense fog under
lifr ceilings.

Improving conditions are expected by mid morning 15z. However,
periods of ifr MVFR conditions will continue under areas of
moderate to heavy rain and low clouds Sunday.

A cold front will quickly cross the area late Sunday morning to
early Sunday afternoon. Gusty showers will be common along the
front with a wind shift to the west to southwest, and brief MVFR
to ifr conditions. Models show llws possible mainly across the
northern sites with h850 winds of around 50 knots mixing down
to below 2000 feet to about 30 knots. If sfc winds become calm
overnight, llws will pose a threat. Therefore, will include llws
at pkb, ekn, and crw for now expecting light to moderate sfc
winds at bkw, ckb and hts overnight after 09z.

Conditions could becomeVFR MVFR behind the front with a quick
improvement toVFR Sunday afternoon.

Forecast confidence and alternate scenarios through 00z Monday...

forecast confidence: low to medium.

Alternate scenarios: timing and intensity of restrictions will
vary, as will gusty winds. Llws could not develop if sfc winds
remain moderate.

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.

There are five sources. 1) Documents and manuals from a variety of sources. 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.
