AREA FORECAST DISCUSSION National Weather Service Wilmington OH 649 PM EST Mon Dec 9 2019
SYNOPSIS. A cold front will move through the region tonight, shunting much of the precipitation eastward. Much colder air will move in behind the front late tonight into Tuesday. Mid week will be cold and dry before temperatures rebound.
NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. Bands of rain continue to lift northeast across the region this afternoon. The holes in the pcpn shield have not filled in as much as previously thought, but most locations have seen some sort of rain today.
Radar is showing that the backedge of the pcpn has pushed through much of Mercer County, and might work a little farther east late this afternoon. Cold front is still to the west and don't expect it to come through until 03-06Z. So kept some chance PoPs in the far nw to cover any redevelopment that might occur with fropa. Elsewhere, expect the on and off rain to continue until the front pushes through. The exception is the southeast counties, where rain chances linger through the night as the moisture transport hangs up. Precipitation type looks like it will be all rain tonight, as the colder air delays until after the pcpn moves through.
Temperatures will remain in the 50s for the first half of the night, then the temperatures will start to tumble with fropa. Lows are forecast to range from the upper 20s in the west to around 40 in the far southeast.
SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/. As mentioned in the near term discussion, pcpn lingers in the far southeast as southwest flow aloft brings a stream of upper support across eastern Kentucky into West Virginia. During the morning hours, the cold air catches up with the lingering pcpn, changing it over to a mix, then all snow before it ends. Any snowfall should be less than an inch. Elsewhere clouds will linger most of the day. Temperatures will hold near steady in the west and will fall in the east during the day.
Surface high pressure will building in from the west Tuesday night. Area should see decreasing clouds. Temperatures will bottom out between 20 and 25 degrees.
LONG TERM /WEDNESDAY THROUGH MONDAY/. Pattern through the end of the week seems fairly consistent. The weekend weather into next week is also consistent but that's not a confidence booster since the increased range in forecast values and large scale phase differences of the patterns is what was consistently in high question.
Wednesday starts as the general cold point of the entire forecast. Highs will reach the lower to mid 30s, which may be a slight increase from daytime readings that will be found in the northwest on Tuesday. Overnight lows in the teens to lower 20s will occur given the proximity of a surface high and entrenched cold air at the surface leading to light winds. Return southerly flow will bump readings slightly during the day on Thursday as the high slides east - generally looking for middle to upper 30s across the region.
The warm advection will be more noted with temperatures not falling as much overnight and hitting the balmy middle to upper 20s. Some lower 20s in central Ohio may persist due winds not having had much time to scour out the lingering cold air. Friday and Saturday will see the warmer air with highs in the middle 40s and lows in the low to mid 30s which are still slightly above normal for this time of year.
The model differences begin on Friday as they come to terms with a system ejecting northeast along the eastern seaboard. Rain on Friday into the overnight period may not make it as far northwest as the models are showing, but the threat of rain on the return northwest flow will be increased on Saturday into Sunday, ending sometime Sunday. Another disturbance is being shown to cross east and increase the threat of rain on Monday. Confidence in the forecast decreases from the initial northwest extent of rain on Friday and then the subsequent pattern beyond. Temperatures were kept close to guidance which seemed to be influenced heavily by climo.
AVIATION /23Z MONDAY THROUGH SATURDAY/. Bands of light rain will continue across the terminals for the early part of the TAF period which may still occasionally reduce conditions to IFR. A cold front will then move across the region bringing light rain to an end. Ceilings will be MVFR and winds will shift to west remaining 10 to 15 kt through the period. Appears that ceilings will lift above 2000 ft before 12Z but then not dissipate area wide until closer to 18Z.

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.
