Area Forecast Discussion National Weather Service Cleveland OH 118 AM EST Sat Jan 23 2021

SYNOPSIS. High pressure over eastern Iowa early this morning will move eastward to Ohio by this afternoon. The high will continue to move eastward through Sunday allowing the next area of low pressure to begin influencing the area by Sunday afternoon. This low will emerge from Texas on Sunday night then move up the Ohio River Valley Monday into Tuesday.

NEAR TERM /THROUGH TONIGHT/. Flow off of nearly ice free lakes continues to produce snow showers across much of the CWA early this morning. Most locations will continue to see a passing flurry or two through the overnight as the better snow showers persist across the east. Lots of dry air advecting into the region which will impact how efficient the lake effect snow will be. However we are colder at 850 mb (around -17 C) than we have been in awhile. So we do think there will be some light accumulations in the higher terrain east of Cleveland into NW PA. Dont think additional snowfall will be more than an inch or two.

Even with the low level drying ahead of approaching high pressure we will need to monitor for some enhanced snow showers that extend back up to Lake Huron. These look as if they would be focused over NW PA but could wobble westward to around Conneaut. These snow showers will bounce around as the high nudges them eastward through the day. Another 1 inch with locally higher possible. High pressure should take control of the entire region at some point this evening. This should help to end the remaining flurries that likely will persist over NW PA through 9 pm. Highs today in the upper teens across NW PA to around 30 across NW OH where some sunshine is expected. Dry for all locations after 9 pm tonight with lows in the teens to lower 20's.

SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/. Generally quiet early Sunday as high pressure just to the east moves farther east and cloudiness increases as warm advection overspreads the region. There is a slight chance of light snow or perhaps mixed wintry precipitation late in the day south of US Route 30. On Sunday night moisture will continue to increase and there is a slight chance again of light snow possibly mixed with freezing rain generally south of US Route 30. Northeast Ohio and nw PA should remain dry. On Monday mixed wintry precipitation with just snow on the northeast edge will spread into the area but timing differences appear as the GFS is more progressive(faster)than the ECMWF short wave over the Mississippi Valley. The NBM pops have been used which could be too low if the recent run of the GFS is correct. On Monday night the low pressure area will be moving across the Ohio Valley just south of the region and allow enough warm air aloft for mixed wintry precipitation to prevail across the region. The GFS is faster with the movement of the system and thus colder on the backside of the system but will lean toward the slower Euro which is more consistent with the NBM data.

LONG TERM /TUESDAY THROUGH FRIDAY/. The upper low will exit the region Tuesday evening with light mixed wintry precipitation ending as snow showers Tuesday afternoon.

The southern stream jet persists across the country through the remainder of the period with generally zonal flow with somewhat of a repeat of the pattern with a system passing by to the south of the region. The pattern is slightly colder and drier with little precipitation expected in the form of snow showers.

High temperatures will be below normal from the upper 20s to lower 30s. Lows will be in the teens to lower 20s.

AVIATION /06Z Saturday THROUGH Wednesday/. Dry air is assisting on lifting ceilings across the region overnight. However there are still snow showers that cover much of the region. NW Ohio is still seeing areas of flurries but further east heavier snow showers are still produce brief MVFR and IFR conditions. High pressure builds into the region today with ceilings scattering out through the morning across the west then gradually spread eastward through the day. The only Non- VFR conditions will be in snow showers that will gradually shift eastward into NW PA by this afternoon. Northwest winds will continue to slowly decrease through sunrise. Winds gradually shift to the west through the day with speeds under 8 knots by mid afternoon.

Outlook . Non-VFR possible snow south Sunday afternoon through Tuesday, some mixed precipitation is possible Monday.

MARINE. Northwest flow prevails across the region with a weak surface trough persisting across the lake. Cold advection is allowing northwest winds generally of 15-22 knots with higher gusts to mix to the surface and this will likely continue into Saturday afternoon. High pressure over the Iowa will gradually build east over the lake by Saturday evening and allow winds to slacken. The high pressure area will remain just northeast of the region into Sunday night as low pressure develops over the Ozarks. The low pressure area will move northeast into the lower Ohio Valley Monday afternoon and upper Ohio Valley by Tuesday morning. Northeast winds will increase early Monday and a small craft advisory is likely that will persist through Tuesday. The surface low will move off the Mid-Atlantic coast by Wednesday morning as high pressure persists north of the lake.
