Area Forecast Discussion National Weather Service Cleveland OH 935 PM EDT Thu Apr 22 2021

SYNOPSIS. High pressure entering from the southwest tonight will move through the Ohio Valley on Friday. Low pressure over the southern Plains on Saturday will move northeast to the Mid- Atlantic states by Sunday. Meanwhile, weak low pressure will develop over the vicinity of Lake Superior and slowly move east through Canada this weekend. A cold front between these systems will cross the area on Sunday morning. High pressure will enter the Great Lakes region on Sunday night for much of early next week.

NEAR TERM /THROUGH FRIDAY NIGHT/. Snow showers and clouds are both dissipating quickly in NE Ohio and NW Pennsylvania as drier air moves into the area. Expecting most of the snow showers to be finished by 11 PM.

Previous discussion . A residual trough over the eastern Great Lakes will finally be pushed southeast of the region tonight as a shortwave trough ripples through the area. The energy with this shortwave will allow for one last chance for snow in NW PA and far NE OH this evening with supporting lift aloft, a marginally cold low level air mass, and some lake induced instability. Clouds are thickening and cooling slightly already over the eastern Lake Erie region and suspect the best chance for snow will be coincident/just after sunset. Accumulations should be minor and impacts will be minimal as snow should be fairly inefficient. Outside of this region, diurnal cumulus has developed across the area this afternoon and will quickly diminish with the loss of daytime heating. Clear skies will allow for temperatures to fall into the 30s across the area and winds will be light enough for a solid frost across the forecast area.

High pressure will enter tonight and move through the Ohio Valley on Friday. With this feature the low level ridge axis will cross the region and temperatures will warm considerably for Friday with a warm air advection regime across the region. Highs should reach the upper 50s, if not into the 60s. Lower temperatures will be found where snow still needs to melt in NE OH and NW PA. With warmer temperatures, diurnal cumulus should develop again during the afternoon hours. High pressure shifts east of the region on Friday night and clouds and rain may start entering late Friday night ahead of our weekend system. However, temperatures should still fall quite a bit into the upper 30s or lower 40s with the diurnal cycle before the aforementioned clouds and rain arrive.

SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/. On Saturday, two upper-level troughs will propagate eastward across the region. The southern one will originate over southern Great Plains Saturday morning working its way east towards the mid- Atlantic by Sunday morning. The northern trough will originate over the northern Plains and move east towards eastern Ontario. At the surface this will result in an elongated area of low pressure propagating eastward across the area with two low pressure circulations north and south of our CWA. Isentropic lift associated with the TROWAL of the southern low pressure system should result in moisture advection and lift for our region. Most models have widespread rain across the area late Saturday afternoon through Saturday night, with a fairly large precipitation shield of light rain north of the southern low. Confidence in very high in a large area of rain impacting the area but there were enough low precipitation outliers (e.g. operational CMC and UKMET) to prevent the addition of 100% PoP at this time. The bulk of the precipitation exits to the east by early Sunday morning, though this round of model forecast data does have some light rain showers lingering into the daytime hours of Sunday, likely due to those models having more differential vorticity moving southeast across the area on the backside of the large-scale trough. High pressure builds in Sunday evening through the overnight period, with the ridge axis centered over the forecast area between 06-12Z Monday. Light winds along generally cool airmass will allow temperatures to get down into the mid to low 30s Sunday night with frost development probable, especially for the eastern half of the CWA.

LONG TERM /MONDAY THROUGH THURSDAY/. By Monday, the surface high pressure shifts east of the forecast area, resulting in the beginning of a big pattern shift for the rest of the forecast period. Light southerly winds develop Monday, resulting in a gradual warmup, though there will be a decent temperature gradient (highs in upper 50s for northwest Pennsylvania while upper 60s in northwest Ohio). Stronger southerly winds will increase the warm air advection magnitude for Tuesday and Wednesday, allowing temperatures to soar into the low to mid 80s for each of these days. A low pressure system may bring precipitation on Wednesday and/or Thursday but there is a significant amount of uncertainty. Thursday will probably be cooler but still above normal temperatures.

AVIATION /00Z Friday THROUGH Tuesday/. Broken stratocu field of 5-8K remains across NE Ohio and NW Pennsylvania with skies tending to clear from the northwest through the evening. A few lake effect snow showers remain across the snowbelt but are decreasing and largely expected to miss the TAF sites. These will tend to lose their connection to Lake Erie through 02Z and drift southeast into Pennsylvania. Clouds will tend to scatter quickly as we move past sunset and remain VFR through Friday. West to northwest winds are breezy at several sites to start the TAF period but will lose their gustiness through 02Z, Light southwest winds of 7 knots or less are expected overnight, becoming breezy with gusts to 20 knots on Friday afternoon.

Outlook . Non-VFR expected with widespread rain Saturday afternoon through Saturday night.

MARINE. West winds of 15 to 20 knots with waves of 3 to 5 feet will continue through the evening, diminishing tonight. For this reason, a Small Craft Advisory for the eastern half of Lake Erie remains in effect through this evening. After a brief lull tonight, the wind shifts to out of the southwest and strengthen to around 15 to 20 knots through the day time hours on Friday. It's possible another round of Small Craft Advisories may be needed but uncertainty was high enough to hold off for now. Winds become light and variable Friday night through Saturday night as low pressure moves across the area. Winds become northwest around 15 to 20 knots with another round of Small Craft Advisory probably needed east of the The Islands during the daytime hours on Sunday. Winds become light and variable Sunday night as high pressure builds east across the region. South to southwest winds expected Monday through Wednesday.

CLE WATCHES/WARNINGS/ADVISORIES. OH . Frost Advisory from 1 AM to 9 AM EDT Friday for OHZ003-006-017. Freeze Warning from 1 AM to 9 AM EDT Friday for OHZ027-036-037- 047. PA . None. MARINE . Small Craft Advisory until 2 AM EDT Friday for LEZ146>149.
