Synopsis
Cold front will continue to move southeastward through the evening.

Dry and seasonable weather can be expected for the remainder of the
week.

Near term until 6 am Tuesday morning
The cold front continues to make its way south, bringing noticeably
cooler and drier air. The front has made it to morgantown, with the
temperature dewpoint dropping 12 9 degrees in a two hour span. It
appears that the bulk of the flash flood threat has come to an end,
but will allow the flash flood watch to continue through its
expiration time of 8pm. Additional light rain has developed across
central ohio, but this rain is likely very light, as there are no
reductions in visibility and one site is even reporting precipitation
with no clouds below 12,000 ft. Measurable rain remains likely near
the front across the southeast, but elsewhere have added scattered
sprinkles through the evening for the rest of the forecast area where
the radar echoes are tracking east.

Cold advection should return temperatures to near seasonal values
overnight, despite some lingering cloud cover.

Short term 6 am Tuesday morning through Thursday
Upper trough will pivot across the region early Tuesday with a
secondary wave deepening said trough. Some lingering showers are
possible, mainly south along the terrain, where moisture pools
through midday, but overall expect conditions to start to dry out.

While upper troughing NW flow will persist through the middle of the
week, surface high pressure should support little more than diurnal
cu. Seasonal or even slightly below seasonal temperatures are expected
given the pattern through the week.

Long term Thursday night through Monday
Temperatures will rebound by the weekend as southerly flow returns
and high pressure slides off the atlantic coast. At this point,
ensemble guidance continues to suggest dry weather through at least
Saturday before increasing gulf moisture on the western edge of the
atlantic ridge returning precipitation chances.

Aviation 00z Tuesday through Saturday
Showers and MVFR conditions will continue at mgw into the evening
hours, but other terminals should remain primarily dry andVFR.

However, some sprinkles have been observed in central ohio, and this
precipitation may reach other airports during the evening hours, most
likely zzv. Confidence in the forecast overnight is a little higher
compared to the 18z TAF issuance; models indicate that while many
sites will have mid level overcast skies for several hours, profiles
should eventually saturate closer to the surface around sunrise,
allowing for the potential of some MVFR restrictions returning. Think
this threat should be relatively short lived, with widespread
diurnal cumulus developing by the afternoon.

Outlook
Vfr will return Tuesday, with prevailingVFR expected for much of
the week, outside of any morning fog.

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 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.
