UPDATE. FOR 12Z AVIATION DISCUSSION.
Showers continue across the area as an area of positive vorticity advection swings through the broad trough/ upper low. The upper low is currently centered over north central Arkansas and south central Missouri. There should be a break in the rain between the broad rain shield that we've experienced over the last several hours and the showers associated with the upper low. The upper low will wobble northeastward along the Ohio River Valley today and be located along the central Illinois/ Indiana border by 00z. A few showers will linger into the overnight hours and temperatures will drop enough on the plateau after midnight for a transition from rain to a rain/snow mix to even a couple pure snow showers. Any leftover moisture will move off the plateau Saturday morning, but clouds will continue to linger. No accumulations or impacts should be expected with any snowflakes that do fly on the plateau.
Models have come into agreement with the next shortwave that will dip out of the northern Rockies on Sunday bringing another chance of some showers mainly Sunday afternoon through Sunday night. Again, soundings show that it may be cold enough to mix in a few snow flakes on the plateau late Sunday night and the first thing Monday morning, but no impacts are expected.
Another wave will eject eastward from the coast of California to the southern Plains by Tuesday morning. This wave will weaken as it approaches our area. The GFS and Euro now show very little, if any, QPF for our area as the weak wave swings through Tuesday night and Wednesday. I kept a slight chance of showers in the forecast as the Canadian does show the wave strong enough to produce some showers for our area, plus previous runs of the GFS and Euro had shown some showers for our area. Some members of the GEFS still do. Models 24 hours ago showed the next trough right on the heels of the Wednesday trough. Now models are digging the next trough much further south into Sonora Mexico which will delay the eastward progression. Meanwhile, a northern stream trough will move through the northern Plains to the Great Lakes from Thursday into Friday. Both the GFS and Euro keep the QPF associated with that disturbance north of us. This would mean a dry end of the work week for us in Middle Tennessee. Overall, confidence in the forecast from Tuesday night through the end week is lower than usual as models have changed quite a bit over the last 24 hours and there is a lot of spread in ensemble solutions.
AVIATION. 12Z TAF DISCUSSION.
IFR conditions continue to plague mid-state terminals as we deal with our latest system. Some improvement is possible this afternoon, climbing to MVFR, but it should be short lived, dropping back to IFR tonight.
Winds will pick up a little throughout the day with occasional gusts of 15-20 kts as the directions swings from south to southwest this afternoon.
OHX WATCHES/WARNINGS/ADVISORIES. NONE.

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.
