AREA FORECAST DISCUSSION National Weather Service Wilmington OH 947 AM EST Thu Jan 23 2020
SYNOPSIS. A low pressure system will begin to bring precipitation to the region beginning late today as rain. The rain will continue into Friday night, when colder air working into the region will bring a rain/snow mix. The precipitation is expected to taper off Saturday night.
NEAR TERM /UNTIL 6 PM THIS EVENING/. Mid and high clouds will move across the region today. A system approaching later today will bring the potential for a few showers across southwestern portions of the forecast area late in the day, however with dry low levels it will take awhile for the column to saturate enough for precipitation to reach the ground. Went close to the blend for temperatures with high temperatures in the 40s.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/. Closed H5 low will continue to dig out of the plains into the mid MS Valley tonight. As this occurs, isentropic lift will increase and at lower level moisture transport will increase. Rain is expected to lift over the fa during the night. Latest temperature guidance is keeping almost everyone above freezing overnight. The one exception could be east of Columbus, where a few pockets of freezing rain may occur. Guidance has temperatures rising towards daybreak, so will not mention it in the HWO at this time. Lows will range from those lower 30s east of Columbus to upper 30s in the nrn KY.
The closed H5 low will lift from wrn TN into srn IN on Friday. Rain chances will remain categorical, but by the end of the day, the pcpn could be scattering out in the west. Highs on Friday will range in the 40s once again.
LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/. Occluded low pressure centered over the Ohio Valley Friday night shifts slowly northeastward through the Great Lakes and into the Northeast throughout the weekend. Initial round of heavier precipitation associated with the occluded front should be shifting east of the forecast area by late Friday night. Not expecting much of a temperature change behind the front as the cold air struggles to advect southeastward from the northern Plains.
Surface low pressure's influence over the region remains through the day on Saturday with abundant low level moisture refusing to vacate the area resulting in continued chances for precipitation. In fact, Saturday looks quite dreary with cloudy skies, rain-snow showers, and temperatures struggling to reach the 40s. It is anticipated the travel hazards will be limited given near surface temperatures a few degrees above normal. Could see some light snow accumulations in grassy/elevated areas with persistent snow showers. Precipitation chances linger into Sunday morning with additional rain-snow showers possible. Low level moisture still fairly high throughout the rest of the day so can't rule out continued flurries into Sunday evening. Surface high pressure builds into the region to start the work week before gradually moving east by Tuesday night. During the day on Wednesday, another closed low moves into the Mississippi Valley, setting the stage for increased precipitation chances on Wednesday night into Thursday.
Temperatures for long term period: Due to the presence of the occluded low, temperature gradients are fairly lackluster with no impressive cold air surges following the passage of the low pressure. High temperatures are near climatological normals and low temperatures around 10 degrees above normal. Daytime high temps struggle to reach the lower 40s area wide Saturday-Monday while nighttime lows hover in the lower 30s under cloudy skies. Even with high pressure moving in Monday and Tuesday, cloud cover fails to break, limiting afternoon highs to the mid 40s.
AVIATION /14Z THURSDAY THROUGH MONDAY/. Ceilings will gradually lower this morning as broad southwest flow increases across the region.
After 18Z lower low levels will begin to saturate around CVG/LUK. Brought in a VCSH just before 00Z, but left ceilings VFR. As H5 low deepens in the plains after 00Z Friday, pva will be increasing. This will push precipitation north across the region. Temperatures should be warm enough for the precipitation to fall as rain at the tafs.
Ceilings in the southern tafs will lower to MVFR around 06Z as the column saturates. For the northern tafs, conditions should remain VFR until the last few hours of the period.
For the 30 hour CVG taf, ceilings are expected to drop to IFR as the rain continues and the atmosphere saturates.
OUTLOOK . MVFR/IFR ceilings and MVFR visibilities likely Thursday night through Saturday night.

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.
