Synopsis
Another cold morning is in store as high pressure completes a
slide across the region. Precipitation chances in the form of
rain and freezing rain return early on Wednesday.

Near term until 6 am Tuesday morning
No major changes were needed for the near-term period as another
cold morning, albeit without the wind chill indices, is in
store as high pressure slides across the region. No changes to
the low temp forecast about 20 degrees under the averages.

Short term 6 am Tuesday morning through Thursday
Temperature recovery back toward the averages can be expected
on Tuesday as strong warm advection ensues in advance of plains
low pressure. A 30 to 35 degree low-to-high spread is anticipated.

That plains low is forecast to dig rapidly toward the great
lakes and continue the warm, and eventually moist advection
over the upper ohio region. Temperature parameters continue to
look sufficient to leave out any snow mention for Tuesday night
as per indications of a much warmer overall atmospheric column
and a later onset time - all consistent with strong warm
advection on the van of low pressure digging well north of the
upper ohio valley region.

The threat of freezing rain will be dependent on lingering sub-
freezing ground temperature after this quick cold snap. Boundary
layer warm advection, condensational latent warming as dewpoints
rise above 32f, and latent heating as any ice forms should
quickly neutralize that potential on Wednesday morning. A hazardous
weather outlook mention was restricted to the more favorable
north and eastern zones of the region where cold will linger
today.

Categorical pops were maintained through much of Wednesday as
forcing for ascent increases with the encroachment of the
systems cold front and strong jet MAX aloft.

By Wednesday night, the systems cold front is expected to cross
the region with residual rain changing to snow showers. Progression
of the front and mid level drying will limit accumulation potential
an inch or two through early Thursday.

Long term Thursday night through Monday
Passage of that front will usher in a period of much colder
weather and periodic snow showers as a broad, high amplitude
trough develops over the conus.

Aviation 04z Tuesday through Saturday
Intermittent MVFR CIGS with light lake effect snow north of i-80 will
dissipate overnight as high pressure continues to build into
the area.VFR and SE winds for the rest of the forecast area
through the TAF period.

Outlook
Restrictions will return Wednesday with the next low pressure
system.

NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code.

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.
