AREA FORECAST DISCUSSION National Weather Service Wilmington OH 606 AM EST Mon Dec 16 2019

SYNOPSIS. Rain and snow will end early today as westerly flow aloft shunts this weather to the east. More upper level disturbances will pass northeast through the region in concert with southwest flow through a deep layer, initiating more rain this afternoon that will mix with and change to snow from northwest to southeast starting this evening. The axis of the upper trough will cross the region early Tuesday, ending any lingering snow and ushering in colder air behind a surface cold front Tuesday night.

NEAR TERM /UNTIL NOON TODAY/. The bulk of the precipitation has ended over the area with a few passing sprinkles, flurries or even freezing drizzle expected through the early morning. Advisories have been cancelled for this morning but more precip is expected to enter before the day is through, and could come in earlier if the leading nose of rain currently found near St. Louis holds together in good southwest flow. Temperatures were on the mark and should not see any more than a degree or two of fluctuation for the next several hours.

SHORT TERM /NOON TODAY THROUGH 6 PM TUESDAY/. Scattered showers in the south and southeast will increase in coverage this afternoon as the a confluent flow of southwest winds through a deep layer of the atmosphere persists. A very broad and weak upper ridge will pass over the region to the northeast today, but the embedded shortwave energy found along and behind it will initiate more widespread activity, possibly beginning as a mix of rain and snow in the northwest.

Surface energy will pass south of the area this evening and then northeast along the spine of the Appalachians tonight. As it does, colder air will be pulled in from the north and any rain will change to snow from northwest to southeast overnight. A period of freezing rain is possible nearest the I-71 corridor where a half inch to inch of additional snow is possible tonight. Northwest of this corridor, snow will be more prevalent for a longer period of time and 1-3 inches are expected here. The better axis of 2-3 inches should occur from a line that extends northeast from Richmond to Piqua to West Liberty, and Richwood.

Ice accumulations will generally be light and should only amount to a glaze but the thermodynamics and timing of how the atmosphere will cool and in which layers remain in a state of flux.

Temperatures have not been changed much with highs today in the 35-40 range and lows tonight within 2-3 degrees of 30, coolest in the northwest. Tuesday will be cooler but not markedly so given the ample cloud cover. Cold air will funnel into the region and high temperatures may occur after midnight tonight. However, models are suggesting that insolation through the course of the day and the drier air may permit readings to reach back to what they were at the beginning of the day. Regardless, we are only looking for a 5-8 degree variance in temperatures from today through Tuesday, including overnight lows.

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/. Upper low diving southeast across Ontario into New England at the beginning of the period will push a cold front across the region late Tuesday night into Wednesday morning. Cannot rule out a few snow showers in central and west central Ohio being somewhat closer to the stronger forcing. But probability is low and so have just included some flurries.

High pressure will build in behind the front and the pass off to the east on Thursday as upper heights rise. Temperatures will be cold, especially Wednesday night into Thursday morning as there should be very good radiational cooling conditions. But readings will start to moderate late in the week.

A mid level trough will pass across the area with maybe a weak surface reflection grazing the region. This will just bring an increase in clouds. Heights will start to build again on Sunday with west to southwest low level flow. Thus expect above normal temperatures over the weekend.

AVIATION /11Z MONDAY THROUGH FRIDAY/. Next 24-36 hours will be the most active with IFR to LIFR cigs prevailing at least in the next few hours through daybreak until mixed precip ends. MVFR cigs will then be occur for the bulk of the daylight hours until the next round of rain pushes in from the southwest in the afternoon, with snow or a mix found at DAY and ILN. Some freezing rain is possible as well and would be more likely from ILN northeast towards CMH/LCK in the evening.

Being that ongoing mixed precip is going to be ceasing over the next 5-7 hours and then another batch move through for the latter third of the forecast, the TAFs will be updated frequently as upstream conditions warrant.

Periods of LIFR cigs and vsbys will be possible both early and late in the valid forecast, but the primary cig will be MVFR beyond daybreak today and vsby IFR. This is until the next batch moves in.

CVG was noting stronger winds towards 0z as they picked up from the nne, gusting to the low 20kts according the LAMP guidance. Seeing the earlier forecast had gusts in, included this in a tempo group that had lower vsbys for a few hours near this time.

OUTLOOK . No significant weather is expected.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
