Area Forecast Discussion National Weather Service Cleveland OH 648 PM EST Wed Jan 22 2020

SYNOPSIS. High pressure over the mid Atlantic states will remain nearly stationary into Thursday as low pressure over the Central Plains moves into the mid Mississippi Valley. The low pressure area will move into the Ohio Valley Friday and eastern Great Lakes on Saturday as a secondary low develops along the mid Atlantic coast.

NEAR TERM /THROUGH THURSDAY NIGHT/. Only change made for this update was adding a trace of ice early Friday morning before 12 UTC for areas southwest. A marginal warm nose may introduce a small area of freezing rain and sleet before transitioning to all rain.

Original discussion . Fair weather can be expected through Thursday afternoon as high pressure remains nearly stationary just to the east of the region. Some high clouds and a southerly surface wind will keep temperatures warmer than last night. Overnight lows will range from the mid 20s out west and along the lakeshore to the upper teens over inland nw PA. On Thursday cloudiness will thicken and lower some in the afternoon as temperatures warm into the upper 30s to lower 40s.

The forecast becomes a little tricky Thursday night. As low pressure approaches Thursday night . moisture will increase especially after midnight and some light mixed precipitation can be expected mainly west of I-71. Low temperatures will be near freezing west of I-71 and may rise toward morning. Thicknesses aloft support mainly liquid precipitation except in the far north and east where some snow could be mixed in. There could be a few hours of light freezing rain west of I-71. POPs will increase overnight especially in the west to the likely category.

SHORT TERM /FRIDAY THROUGH SATURDAY/. Low pressure will approach the Ohio Valley Friday with precipitation overspreading the area by late Friday morning into early Friday afternoon. Precipitation will likely begin as a rain/snow mix early Friday morning before a quick transition to rain takes place as warm air advection and surface temperatures increase throughout the day. Southeast winds will gradually increase to around 10 knots in most areas with up to 15 knots found along the northeast lakeshore late Friday night. Precipitation will quickly move east across the area on Friday with the heaviest rain expected early Friday afternoon and evening before tapering by Friday night. Most areas should expect to see a quarter up to a half inch of rain through Saturday morning. As the low center tracks across northern Ohio Saturday morning, cooler temperatures aloft will begin to trickle in behind the system. Surface temperatures look to remain above average through the short term period with highs in the upper 30s to low 40s on Friday and Saturday.

LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/. As the low pressure system begins to move into New England Saturday night into Sunday morning, flow will become northwest off Lake Erie, with -6C 850 mb temps sufficient enough to support marginal lake- effect snow ad/or rain showers along the primary and secondary snowbelt areas. The most recent runs of the ECMWF and CMC models have suggested that there could be a period of heavier snow and/or rain late Sunday afternoon into Monday morning, but more details will be hashed out in upcoming forecasts on amounts and timing since surface temperatures will be at or just above freezing. Towards the end of the long term period, a low pressure system is expected to develop across the southern Plains to the Missouri Valley Tuesday night and approach the Ohio Valley by Wednesday night. Above average temperatures will continue to be found across the area through the end of the long term period with highs in the low 30s to upper 40s.

AVIATION /00Z Thursday THROUGH Monday/. VFR conditions will persist through the TAF period as high pressure over the mid-Atlantic states slowly shifts east. The air mass will remain relatively dry with just high cirrus clouds expected through tonight. Toward midday Thursday, some mid-level clouds may spread in from the southwest. Light southerly winds of 10 knots or less are expected through the TAF period. Non-VFR conditions begin to approach TAF sites after 00 UTC Friday from the southwest with possibly mixed precipitation.

OUTLOOK. Non-VFR possible with mixed precipitation late Thursday night and then with all rain on Friday. This transitions to a rain/snow mix on Saturday that lingers across the area on Sunday. Light lake effect snow possible Sunday night into Monday across northeast Ohio and northwest Pennsylvania.

MARINE. Generally light winds are expected across the lake throughout the first half of the forecast period with winds remaining 10 knots or less. Southeast winds will increase to about 10-15 knots by Friday night into Saturday morning, then shift to northwest flow by Sunday morning which will result in waves 3 feet or less.

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