Short Term. (Today and tonight) Issued at 245 AM EST Tue Feb 25 2020
Expect persistent dreariness roughly along the I-64 corridor, as a trough lingers over the Ohio River today and tonight. Low clouds could get low enough to cause some visibility issues this morning, but we should ceilings lift at least a little this afternoon. Temperatures won't rise too much during the day today, but most should get into the 50s, if not mid 50s across our southern KY counties, where southwest winds will persist today. Cloud cover and the location of that surface trough should keep temperatures from falling too much tonight over most of central Kentucky. Our southern IN and north central KY counties should drop to around 40, if not into the 30s by daybreak Wednesday. Precip chances return by daybreak as well, as an upper trough rotates into western KY. At this point, it looks to be all rain through tonight.
Long Term. (Wednesday through Monday) Issued at 320 AM EST Tue Feb 25 2020
At the start of the period, a broad upper level trough will be in place over the region, with a strong shortwave swinging through the base of the trough. In response to the upper level forcing, a surface low is forecast to develop over the OH Valley. Expect precipitation to spread across the area by Wednesday morning, initially starting off as all rain. However, as cold air advection kicks in during the day under northerly low-level flow, expect a transition to a rain/snow mix. Not expecting much in the way of accumulations given the warmer ground temps, but overall best chances to see a dusting to light accumulation of snow will be across southern IN and across north- and east-central KY. As the low pressure system moves off to the northeast Wednesday night, precip will taper off from west to east.
Temperatures on Wednesday will start off in the upper 30s to lower 40s and then fall into the upper 20s to lower 30s by Wednesday night. Expect stronger winds by Wednesday afternoon under a tightening pressure gradient on the backside of the surface low, with sustained W/NW winds in the 10-15 mph range and gusts to 35 mph possible.
Drier and colder conditions will take hold on Thursday behind the departing system as we remain under northwesterly flow aloft. Model guidance continues to suggest a couple disturbances may move through the upper level trough Friday and Saturday, bringing slight chances for precipitation to end the week. However variations in guidance continue to lead to low confidence in exact timing and location of these clipper systems. Overall, high temperatures will remain in the upper 30s to low 40s Thursday - Saturday, with low temperatures dropping into the low to mid 20s each morning.
By Sunday, surface high pressure will have built in over the region with upper level ridging moving overhead, allowing temperatures to begin warming back to climatological normals under southwesterly flow.
Aviation. (12Z TAF Issuance) Issued at 635 AM EST Tue Feb 25 2020
Low pressure currently near Louisville this hour. A trough of low pressure along the Ohio River will keep the worst conditions roughly along the I-64 corridor, with HNB/SDF likely to see LIFR /IFR conditions for an extended period today into tonight. We could see a brief improvement in ceilings later this afternoon, especially at KBWG and KLEX . but with sunset and as the night goes on expect a return to IFR conditions. Another wave coming in overnight will bring back precip chances as well. Winds in the vicinity of the low will be somewhat variable, but should become westerly/northwesterly by daybreak Wednesday.

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.
