AREA FORECAST DISCUSSION National Weather Service Wilmington OH 1245 PM EST Tue Jan 19 2021

SYNOPSIS. A weak disturbance is providing light snow across the Ohio River this morning. Light snow showers are expected Tuesday evening as a weak disturbance moves through the northeast. High pressure and drier conditions build back into the region Wednesday. A dry cold front moves through on Thursday followed by high pressure into Saturday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Radar echoes still indicating light snowfall traversing across our southeastern counties at 14z this morning. The light snowfall combined with near-surface and pavement temps above freezing allowed for the cancellation of the Winter Weather Advisory across those southern counties. OHGO cameras confirmed the limited amounts of snow accumulation occurring as well.

For many of our counties north of the Ohio River, plentiful sunshine will be in store for today as a window of clear skies is observed on satellite imagery. As snowfall across our south pushes eastward this morning, rapid clearing will occur over those counties - providing mostly sunny skies by the afternoon. Winds will begin to shift towards the southwest by the afternoon around 5-10 kts. High temperatures will top off in the middle 30s to lower 40s.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/. Update (630AM) . High resolution guidance is suggesting the potential for low level instability to increase this evening given rapid cooling of temperatures aloft (850mb). In response to this and the forcing along the weak front, reflectivity guidance is showing enhanced snow showers traversing through southwest portions of the forecast area where PoPs are currently 30 or less. This potential is beyond the evening commute so the overall impacts would be less. However, temperatures will be decreasing behind the front and 10-15 knots of NW wind, making this situation more concerning than previous days where this was mentioned.

Previous discussion (300AM) . Water vapor imagery already showing signs of the next trough set to move through the region Tuesday evening into early Wednesday morning. Unlike the flat trough from Tuesday morning, this shortwave is pronounced and moving very quickly through the Great Lakes. However, moisture is a bit starved with this quick moving trough, with the greatest moisture favoring northeast portions of the forecast area. While the threat for snow only lasts a few hours, a few tenths of an inch are possible, primarily across the northwest, before the shortwave quickly moves off to the east. Lingering flurries into the late morning are possible, but overall, drying conditions and clearing cloud cover are expected the rest of the short term as surface high pressure builds back in to the Ohio Valley.

Increasing winds and sky cover help keep temperatures elevated into the low to mid 20s for the north and upper 20s in the south Tuesday night. During the day on Wednesday, winds shift from northwest to southwest, but a colder airmass will be in place, limiting high temperatures to the upper 20s and low 30s.

LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/. For Wednesday night, a surface ridge will be moving to the east while a cold front approaches from the west. Low temperatures will occur early (in the 20s) as southerly flow will increase overnight, pushing temperatures into the lower to mid 30s by morning.

For Thursday into Thursday night, a high majority of models and ensemble members concur that deep moisture return will be lacking ahead of the cold front due to a west/northwest mid level flow. Thus, will go with a dry forecast as the cold front pushes east/southeast through the area. Highs on Thursday will range from near 40 north to the mid 40s south. Despite some warmth, it will be brisk with wind gusts as high as 25 knots possible in the afternoon. Lows Thursday night will cool back down into the 20s.

A northwest flow pattern will continue across the Great Lakes and Ohio Valley Friday into Saturday. A weak front is expected to cross the region on Friday, followed by high pressure on Saturday. CAA behind the front will bring some stratocumulus clouds on Friday with perhaps a passing flurry. Sunshine is expected all locations by Saturday as the high builds south into the region, allowing clouds to thin. It will be seasonably cold for late January.

The next weather system is expected to affect the Great Lakes and Ohio Valley late in the weekend and into early next week. Although models differ on strength and timing of frontal systems, the chances for pcpn will increase. Have broad brushed this time period with increasing chances of rain/snow late Sunday into Sunday night, continuing into Monday. Temperatures should moderate some by Monday ahead of a frontal system.

AVIATION /18Z TUESDAY THROUGH SUNDAY/. Prevailing VFR conditions will continue through the afternoon/evening hours. Southwesterly winds remain below 10 kts during this time frame as well.

Shortly after 00z Wednesday, introduced a lowering to MVFR CIGs at KDAY, which will work their way to the remaining taf sites over the next couple of hours. This is driven from a shortwave trough ejecting through the region, which will also produce scattered snow showers that will likely be observed across all taf sites overnight. However, the better moisture/energy remain further north, so KCVG/KLUK may not observe any snowfall, but still kept in VCSH for now. Due to the light/scattered nature of these snow showers, did not lower vsbys below VFR tonight, but future updates may need to be made if confidence is higher on a widespread reduction in vsbys. Otherwise, amendments during the onset of the event should handle any short-lived vsby reductions from the snow bands. In tandem with the MVFR CIGs, southwesterly winds will shift towards the west-northwest and increase to around 10-15 kts, with gusts up to 20-25 kts. Winds will subside late Wednesday morning to around 10 kts or less with a subtle shift back towards the west-southwest.

MVFR CIGs appear to lift back into VFR category near the end of the taf period. The KCMH/KLCK could see MVFR linger a bit longer into the early afternoon Wednesday, but a general clearing pattern will be expected Wednesday afternoon across all sites.

OUTLOOK . MVFR ceilings possible Thursday and Friday.
