AREA FORECAST DISCUSSION National Weather Service Wilmington OH 938 PM EST Fri Dec 13 2019
SYNOPSIS. Rain will overspread the area tonight into Saturday ahead of low pressure traveling across the Appalachians. Drier weather will accompany high pressure later Saturday through Sunday. Precipitation returns Sunday night and Monday when low pressure is forecast to push through Indiana and Ohio.
NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. Rain is moving from the south ahead of low pressure traveling up the Appalachians along the eastern flank of an upper trough. A quarter inch of rain has been recorded in southern locations with another couple tenths probable overnight in continued moisture advection and lift ahead of the low.
Overnight, some snowflakes may mix in across central Ohio but thermal profiles are forecast to be near/above freezing up to 2000 ft AGL. Thus, most snowflakes falling into the column will likely melt. Little to no snow accumulation is expected where there is some mix-in of snowflakes.
It should also be mentioned that the lower atmosphere moisture profiles are supportive of fog formation across the CWA tonight with increasing moisture and calm winds. However, the steady rain may act to mix the low levels enough so as to preclude the development of dense fog.
SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/. Precipitation will be exiting the western CWA Saturday morning and linger in the east through the afternoon as a strengthening cyclone forms over the eastern seaboard. Increasing westerly winds will usher on cool air from the west, which will help keep temperatures down Saturday with highs near 40 across the area. Some flurries might be possible Saturday evening/night due to the presence of low-level moisture, but confidence is not high enough to include in the grids at this time -- especially with the gradual loss of saturation in the DGZ. Currently, just have partly/mostly cloudy skies with lows in the mid 20s across the west and near 30 across the east.
LONG TERM /SUNDAY THROUGH FRIDAY/. The first part of Sunday should be quiet before the next weather system affects the region by Sunday night. Weak surface high pressure will extend across the region. Under partly to mostly cloudy skies, highs will range from the lower 30s north to near 40 south.
Low pressure is forecast to organize across the Arklatex region Sunday night. Ahead of this low, a warm front will begin to advance northeast toward the Ohio Valley. Warm, moist ascent in the form of a low level jet is expected to pivot northeast well ahead of the low, which should spread a shield of pcpn east/northeast into our region. Pcpn will begin as a rain/snow mix far south with snow expected to the north as the pcpn shield advances. Warmer air aloft will eventually allow for some sleet and freezing rain to mix in late across parts of the north. Although lows will range from the mid 20s north to the lower 30s south, temperatures will begin to rise along and south of the Ohio River after midnight.
For Monday into Monday night, as mid level s/wv energy pivots northeast from the southern Plains to the Great Lakes, aforementioned low pressure will deepen some as it moves northeast across the Ohio Valley. There are some strength and timing differences among the deterministic operational model runs with the ECMWF being the slowest and and slightly deeper. That being said, have taken a blend with pcpn transitioning more over to rain from south to north through the day as temperatures warm above freezing. The far northwest may remain a rain/snow mix. Accumulating snow will be possible Sunday night into Monday, along with some light ice accumulations (especially along and north of I-70) before temperatures warm above freezing. For now, have gone with an inch or less mainly south of the Ohio River with 1 to 3 inches north of the Ohio River. There will also be the potential for some moderate to locally heavy rain in our southeast due to another low level jet surge in association with the low. For Monday night, as the low pressure moves by to the northeast, pcpn will taper off. Highs on Monday will range from the mid 30s northwest to the lower 50s southeast. Lows Monday night will range from the lower 20s northwest to the lower 30s southeast.
The mid level flow will become northwesterly Tuesday into Wednesday. This will allow for colder air to move into the region along with surface ridging. Highs in the 30s on Tuesday will drop into highs the mid 20s to the lower 30s on Wednesday. Lows Tuesday night will be cold in the teens.
For Thursday into Friday, high pressure will move east. Temperatures will moderate into the 30s and 40s. Some uncertainty exists as to whether the next weather system will affect the region either late Friday or Saturday, so have kept the forecast dry.
AVIATION /03Z SATURDAY THROUGH WEDNESDAY/. Low pressure will be crossing the Appalachians tonight before reaching the mid Atlantic Coast on Saturday. Flight conditions will grow steadily worse tonight as rain moves in and produces a saturated boundary layer. We can expect IFR conditions tonight to Saturday morning, with snow mixing with rain at DAY and ILN. Some improvement to MVFR is forecast later Saturday as drier begins to work in on an increasing west to northwest flow. A retreat to IFR will be possible Saturday night at CVG in low level moisture convergence along a weak trough.
OUTLOOK . MVFR ceilings will linger into Saturday night. MVFR to IFR ceilings and visibilities are likely again late Sunday night into Monday 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.
