Area Forecast Discussion National Weather Service Cleveland OH 1101 PM EST Fri Nov 27 2020

SYNOPSIS. A weak cold front will move through the area overnight, followed by high pressure building over the region for much of the weekend. Attention will then be on two upper level low pressure systems, one in the northern stream near the Dakotas, and a southern stream low near Arizona. These lows are projected to phase into a larger cut off low Sunday and then rapidly deepen as it lifts into the Ohio Valley. This system will track into the lower lakes on Monday, bringing a chance for rain, snow, and gusty winds for the early part of next week.

NEAR TERM /THROUGH SATURDAY/. The cold front has entered the western part of the area late this evening, with the initial showers now moving east out of the area. Some lake effect/enhancement may ramp up over the next several hours across the snow belt with some weak lift and 925-850mb moisture moving through the area with the front.

Original discussion . Shortwave trough just to our west expected to rotate across the area overnight. Looking upstream there are radar returns but not seeing any ground reports of precip. Expect to see an uptick in clouds with the frontal passage but not looking at any precip for most of the area. However, there will likely be increased instability over the lake from the subtle cooling aloft, resulting in some isol/sct rain showers over the primary snowbelt areas. Temperatures will drop into the 30s overnight, coolest in the west as drier air filters in. The flow off the lake will keep some clouds ongoing in the east into Saturday morning. In the west, some analysis suggests some shallow moisture lingering that could briefly get trapped under an inversion in the morning, which is common this time of year. For now am banking on enough mixing and drier air advecting in to prevent this. Temperatures will reach the mid 40s for much of the area Saturday thanks to some sun returning. High pressure will back winds to the southwest on Saturday night into Sunday. Mostly clear skies Saturday night will drop temps to around freezing. However, sunny skies will start off the day Sunday and with SW winds expect temperatures to warm above normal with highs in the 50s.

SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/. Sunday night will mark the transition from high pressure to a very active weather pattern. A low pressure system originating over the Gulf Coast states is expected to deepen as it tracks northeast along the spine of the Appalachian Mountains. Aloft, a deep trough is expected to extend the entire eastern CONUS, producing a cut-off low aloft by Monday evening. Southerly winds across the area overnight on Sunday will result in moisture values increasing from south to north. Isentropic upglide ahead of the low pressure will allow for showers to begin to develop overnight Sunday. Due to the magnitude of warm air advection on Sunday, lingering into the early overnight hours, initial precipitation across the area should remain as rain. Low temperatures overnight on Sunday are expected to remain above freezing at the surface with temperatures in the mid to upper 30s.

On Monday, rain will transition to snowfall across the area from west to east as the cold air mass moves over the area. The exact timing of this transition remains uncertain at this time with it being dependent on the low pressure track. Long range models are becoming more consistent with the overall track, however confidence remains low this far out. The Canadian model suggests a straight path northeast for the center of the low, however the ECMWF and GFS both suggest a retrograding low pressure over the eastern Great Lakes. Current thoughts remain similar to the previous forecast, with rain showers persisting into Monday afternoon before turning to a mix of rain/snow for the western portion of the area, and eventually all snow overnight Monday. With such a cold air mass moving over the area with this system, once the precipitation changes over to all snow, it will likely remain snow through the end of the event. The transition to rain/snow Monday afternoon will also mark the approximate timing of increased northwesterly winds across the area with 10 to 20 mph sustained winds, gusting to 30 mph west of I71. High temperatures in the low to mid 40s on Monday will likely occur in the morning, steadily falling throughout the day as cold air advection increases over the area. The overnight low on Monday dips down into the mid to upper 20s across the area.

As the system moves northeast of the CWA, a transition from synoptic snowfall to lake effect snow will occur. Monday night into Tuesday, winds will be from the north to northwest, resulting in 850mb temperatures dropping across the area to at least -8 deg C. The is a lot of uncertainty about the exact temperatures across the area Tuesday, with some ensemble models being as cold as -14 deg C. This temperature will need to continue to be monitored as it has the potential to significantly alter the lake effect contributions to QPF. Initial lake effect snowfall will likely occur for portions of the lake effect snowbelt in Ohio, and slowly transition to encompass the entire snowbelt through NW PA as winds shift and become more westerly. High temperatures on Tuesday will only be in the low to mid 30s.

With this being the first widespread, impactful snow event for the area, there is a lot to digest with this system. Much of the area is expected to receive measurable snowfall with this event. Although exact amounts are uncertain this far out, the highest amounts of snowfall related to the synoptic forcing will be west of I71. Models are becoming more consistent to have at least 2 to 4 inches of snowfall across this western portion with 1 to 2 inches east of I71. Total snowfall this far out is extremely difficult to anticipate as many factors will contribute to the snow accumulating. Factors that will continued to be monitored for the synoptic system include: exact track of the center of the low, timing of transition from rain to snow, ground temperatures, and total QPF expected.

LONG TERM /TUESDAY THROUGH FRIDAY/. As mentioned in the short term discussion, sometime on Tuesday will mark the transition from synoptically driven snowfall to primarily lake effect snowfall. Westerly winds linger into Wednesday, along modest lake enhanced instability, resulting in chance PoPs for the snowbelt areas in far NE OH and NW PA into the overnight hours on Wednesday. Exact snowfall totals from the lake effect snow showers will be dependent on the 850mb temperature and exact placement of the center of the low, as this will determine the exact wind direction across Lake Erie. Overnight low temperatures on Tuesday will be in the mid 20s, warming up to the upper 30s on Wednesday.

Long range models are suggestive of the potential for another strong low pressure system to move along a similar track next weekend. Opted to put slight chance of PoPs beginning Friday as timing of this system is uncertain this far out. High temperatures for much of the long term look to be near normal for this time of year.

AVIATION /00Z Saturday THROUGH Wednesday/. Stratus remains locked in across most of the terminals this evening, with some breaks in the low clouds. A quick moving cold front will bring some MVFR ceilings again for most of the terminals through the 06Z-12Z hours from west to east before clearing occurs. IFR potential looks low but non zero at this point. A few scattered SHRA possible at the eastern terminals ahead of the front but should have minimal impact to flight cats. West winds become more northwesterly briefly in the wake of the cold front, but back southwesterly for the second half of the period as the ridge builds into the area.

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

MARINE. A fairly weak cold front will cross Lake Erie overnight, with winds turning to the were turning more NW, but little increase in speed. With high pressure building over the waters this weekend winds will again back out of the SW by Saturday night. A strengthen storm system will track near the western Appalachians and over the lower lakes Monday into Tuesday. This feature will deepen as it approaches the area, increasing the pressure gradient, resulting in gusty conditions with advisory level winds likely. Cold air filtering in behind this feature will support a prolonged advisory level scenario.

The forecast track will greatly influence the winds speed and fetch potential, and currently there is a fair amount of uncertainty. Given some scenarios, an extended northeast wind Monday could develop resulting in high water levels in the western basin. Conditions will need to be monitored for possible lakeshore flooding.
