Short Term. (Today and tonight) Issued at 310 AM EST Sat Dec 7 2019
Sfc high pressure centered over Illinois and Indiana early this morning will build eastward over Ohio and Pennsylvania later today. The northern edge of a stratus layer is now south of I-64, with clear skies across southern IN and northern KY. The clearing line will only slowly move south this morning, so a mostly cloudy start for southern KY.
NNE winds will veer easterly during the daytime as the sfc high off to our north slides to the east. Consensus highs for this afternoon range from the mid 40s in southern IN to the lower 50s in southern KY. Due to high pressure off to the east and a strengthening Hudson Bay low, SW return flow increases early Sunday. A 30-35 kt SW LLJ develops by 09-12z Sun, which will keep temps steady or rising during that time. This could result in a tighter temp gradient for lows tonight. Sheltered areas in the Bluegrass could dip to 30 or even upper 20s, with some areas in southern KY not dipping below 40.
Long Term. (Sunday through Friday) Issued at 254 AM EST Sat Dec 7 2019
A strong, +120kt 300mb jet part of a broad upper level trough will begin ejecting into the southern Plains on Sunday. Models indicate lee cyclogenesis over the western Central Plains as the trough advances eastward with very cold Arctic air in Canada being drawn southward. In our neck of the woods, Sunday should stay dry, though clouds will gradually increase during the day. Showers begin developing after midnight Sunday as the region falls into the left exit region of the strong upper level jet while a strong LLJ advects GoM moisture northward. Overall setup looks like a classic isentropic lift event with light to moderate rain showers, so will continue advertising very high PoPs for the Monday timeframe.
The strong cold front will advance quickly from the Plains into the Ohio Valley by Monday night. Precipitation won't immediately end behind the front given the shallow nature of the cold, Arctic air and lift/dynamics at play, which could result in a transition to wintry precipitation if moisture lingers long enough. The majority of guidance moves precipitation out of the region before this becomes an issue . but it'll be something to watch closely.
After Tuesday, expect cold and dry weather to persist into the end of the week as an Arctic high dominates the northern US east of the Rockies. The high should push east of New England by Friday and return flow around the high becomes southerly over southern Indiana and central Kentucky, resulting in some moderation to temperatures. Another system may take aim at the region late Friday into Saturday, though timing and confidence remain low this far out.
Aviation. (12Z TAF Issuance) Issued at 609 AM EST Sat Dec 7 2019
BKN MVFR stratus lingers this morning south of a line from roughly EHR to FTK to IOB. Fuel alternate ceilings continue to impact BWG and a relatively narrow swath across far southern KY. Fuel alternate is expected to improve to MVFR above 2 kft by 14-15z, with prevailing VFR conditions by 17z. As clouds slowly scour out this afternoon at BWG, the northern terminals will enjoy a sunny day. Northeast winds will veer easterly this afternoon diminish slightly as high pressure slides by off to our north.
Marginal LLWS scenario develops by 09z Sun with a strengthening SW low-level jet. Expect 30-35 kts at 2 kft 09-12z Sun. After a brief clear period this evening into tonight, clouds will also be on the increase Sunday morning. Mainly VFR clouds expected, though HNB could approach MVFR conditions by 12z Sun.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
