Area Forecast Discussion National Weather Service Cleveland OH 946 AM EST Sat Nov 28 2020

SYNOPSIS. High pressure will build over the region this weekend. Attention will then be on low pressure developing near the Gulf Coast that will track north to Pennsylvania on Monday and linger over the eastern Great Lakes on Tuesday. This system will bring a combination of rain, snow, and gusty winds for the early part of next week.

NEAR TERM /THROUGH SUNDAY/. Stratocu continues to form off of Lake Erie bringing partly to mostly cloudy skies to lakeshore areas in NE Ohio and NW Pennsylvania. Increased cloud cover in the forecast for these areas for the morning with a gradual clearing trend through the afternoon.

Previous discussion . A weak cold front has moved across the area early this morning. Clouds are slowly clearing from west to east across the region with the clearing line near I-71. High pressure will build in across the Ohio Valley this weekend. Skies will be generally mostly clear today through Sunday. Temperatures will be close to seasonable levels this weekend. Highs today and tomorrow will be in the 40s to near 50. Lows tonight will be in the lower 30s.

SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/. Main concern of the short term period is the potential for moderate snow accumulation across the region, particularly along the I-71 corridor and along the primary and secondary snowbelts of NE OH and NW PA. Confidence is slowly increasing on timing and location of the heaviest axis of snow, but will continue to monitor trends through the weekend. Snow headlines will likely be needed sometime Monday night through Tuesday night.

On Sunday night, subtropical jet energy will phase with an energetic polar jet, allowing a PV intrusion of stratospheric air down into the troposphere. Forecast soundings on Monday night have the tropopause as low as 500 mb. This will be a dynamic and quite anomalous synoptic system with 500 mb height anomalies at least 4 standard deviations below climatology via NAEFS and ENS.

Low pressure will deepen slightly throughout the day Monday, with forecast high temperatures in the mid to upper 30s west of I-71. On the "warm" side of the low, high temperatures could reach the low to mid 40s across NE OH and NW PA. Precipitation is expected to begin early Monday morning across the area in the form of a rain/snow mix west of I-71 and mainly rain east of I-71. A changeover to all rain is possible across the area for at least a few hours during the day Monday as temperatures warm slightly, though a continuous rain/snow or even all snow scenario is possible along the I-75 corridor throughout Monday. It will be blustery Monday and Monday night, with gusts up to 30 to 35 mph possible, especially along and west of I-71.

By Monday evening, colder air arrives, with at least a rain/snow mix expected across the entire area, though an all snow scenario is likely along and west of I-71. By Monday night, widespread snow is expected across the area with lake-enhanced/wrap-around moisture from the low pressure system as it reaches the Northeast and its motion slows. This is the likely the beginning of the heaviest period of snow, as the DGZ lowers into areas more favorable areas of omega. This period/s of snow should last well into Tuesday. Also of note, blustery conditions will remain through Monday night, with windchill in the low to mid teens possible.

Snow will continue across the area Tuesday, becoming moderate to possibly heavy at times, especially along and just south of the lakeshore vicinity, becoming enhanced by a relatively warm Lake Erie in the mid to upper 40s and in any higher elevation areas. The GFS and its ensembles are particularly aggressive with snow totals during this period, being several inches higher than other guidance and deterministic guidance. Upon further inspection, this may be due to the GFS having a more favorable DGZ/omega crossover. Snow will begin to taper by Tuesday night as height rises and drier mid- level air arrive from the west.

LONG TERM /WEDNESDAY THROUGH FRIDAY/. As the snow begins to exit the region on Wednesday, the main story will be the cold and windy early Wednesday morning, with windchill in the single digits possible across the highlands from Mansfield to Marion. Some lingering lake effect snow may be possible across NE OH and NW PA Wednesday morning, before diminishing by Wednesday afternoon. Additional light snow accumulations are possible. Brief high pressure will attempt to build in from the southeast on Thursday, before another low pressure system develops across the southern Tier of CONUS on Friday. Temperatures will be slightly below normal Thursday and Friday with highs in the upper 30s to lower 40s.

AVIATION /12Z Saturday THROUGH Wednesday/. The stratus deck of clouds have almost cleared out of our eastern areas. Some MVFR ceilings may be possible for a few more hours for YNG and ERI. All TAF sites will see VFR later this morning through the time period. Winds will continue to westerly to southwesterly around 5 to 10 knots for this TAF period.

Outlook . Non-VFR likely Monday and Tuesday and may continue into Wednesday for the Snowbelt region.

MARINE. Have issued a Small Craft Advisory for Lake, Ashtabula, and Erie nearshore zones through at least the morning. Have kept Erie through this evening given the more favorable fetch. Winds will shift more southwesterly and southerly, 15 to 20 knots, tonight through tomorrow so although a Small Craft Advisory may be needed, given the offshore flow, conditions appear very marginal. A low pressure system will track northeast across the Ohio Valley on Monday, shifting winds towards the north, 15 to 20 knots, increasing to 20 to 25 knots by Monday afternoon. North to northwest flow, 20 to 25 knots will persist through Tuesday. As the pressure gradient continues to tighten on Tuesday evening, west to northwest winds may further increase near 25 to 30 knots Tuesday evening and overnight. West winds, 20 to 25 knots will continue through Wednesday. A Small Craft Advisory will be needed sometime Monday morning and will likely continue through the period.

CLE WATCHES/WARNINGS/ADVISORIES. OH . None. PA . None. MARINE . Small Craft Advisory until 11 AM EST this morning for LEZ147- 148. Small Craft Advisory until 10 PM EST this evening for LEZ149.
