Area Forecast Discussion National Weather Service Cleveland OH 737 PM EDT Sat Apr 10 2021

. 00z TAF Aviation and Near Term Forecast Update .

SYNOPSIS. Low pressure will move northeast across western Lake Erie by Sunday evening. The low pressure system will force an occluded front to move northeast across the area overnight. The surface low pressure system will dissipate over Lake Erie by Monday morning with a lingering trough southwest to southern Indiana. Low pressure will redevelop over Lake Erie Tuesday and force a cold front east across the area Monday night. A series of troughs of low pressure will move south across the local area through the end of the week.

NEAR TERM /THROUGH SUNDAY NIGHT/. 715 pm update . We made some small adjustments to the hourly precip chances this evening to better reflect the latest radar trends. The rest of the ongoing forecast is on track at this time.

Previous discussion . A potent upper level low pressure system will move gradually into the lower Great Lakes by Sunday morning. This low will be vertically stacked over the lower lakes with a surface low pressure system. The surface low will force an occluded front to move northeast across the area tonight. A swath of moisture will continue to stream north during the rest of the afternoon into tonight ahead of the front. Some thunderstorms are developing well ahead of the occluded front at this time and this trend is expected to continue through the evening. Model soundings supporting fairly strong helicity across the area with minimal CAPE. Storms that develop across the area will need to be monitored through the evening hours for rotation; especially across the western two thirds of the forecast area. Marginal risk was expanded back further east again for this afternoon and evening hours.

Once Occluded front passes through the area, showers will continue across the area overnight and then gradually taper off from west to east during the day tomorrow. Surface low will keep a chance for showers across the area during the day tomorrow. Cold air advection will follow the front tonight and this will knock temperatures back into the 50s and lower 60s Sunday and lows in the upper 40s to lower 50s tonight and 40s Sunday night.

SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/. A broad low pressure, and associated upper level trough, centered over the central Great Lakes region will impact the area for the beginning of the week. This system will become nearly stationary for the beginning of Monday, with a boundary lingering just northeast of the area. Although not very strong, this boundary, coupled with lingering low level moisture and ample upper level support, will provide just enough lift to produce scattered showers, particularly in areas east of I77. The drier air aloft should keep precipitation fair light with minimal chances of thunder. If the boundary stalls closer to the CWA, these showers may shift to increase chances in western areas as well. During the day on Monday, highs are expected to be in the low to mid 60s due to the continued WAA across the area.

By Monday evening, another trough over the northern Plains will merge with the aforementioned trough and begin to meander east, although not quickly. By Monday night, CAA will increase behind a weak front, resulting in low temperatures dipping down into the low to mid 40s. As this system continues east, and eventually off the East Coast by Tuesday evening, chances of precipitation will also diminish from west to east as drier air moves over the area and temperatures will become closer to normal with highs in the mid to upper 50s. Current forecast suggests some lingering, isolated showers in NW PA overnight on Tuesday, however confidence is rather low. The GFS continues to suggest that the dry air will move in a touch slower, allowing showers to linger into the overnight hours on Tuesday. With high uncertainty, this will need to continue to be monitored for the potential of more widespread showers. Overnight lows on Tuesday will dip into the upper 30s to low 40s.

LONG TERM /WEDNESDAY THROUGH SATURDAY/. Some showers may linger into the beginning of the long term forecast as the aforementioned low pressure continues eastward. An upper level ridge is expected to build across the Central Unites States, allowing a high pressure at the surface over Canada to move southeast over the area. This will bring relatively drier air over the area along with weaker upper level support, resulting in diminishing chances of showers. The caveat with this high pressure is as it moves southeast from Canada, cold air will accompany it, allowing temperatures to remain closer to normal with highs in the 60s and overnight lows in the 40s. Overall, the long term forecast looks to remain relatively dry but with cooler temperatures compared to recent high temperatures across the area this spring.

AVIATION /18Z Saturday THROUGH Thursday/. The main aviation impacts expected will the showers this evening and ceilings lowering to marginal MVFR through the evening as well as brief visibility drops due to heavier showers. We have taken out any mention of CB or TSRA for this evening as the probability is extremely low for any convection to impact TAF locations. Light to moderate showers will slowly end from west to east across the after after 06z. We may have a dry slot where clouds will clear out or lift to VFR early Sunday morning. Widespread MVFR ceilings will move back in across the area by Sunday afternoon with scattered off and on light rain showers. Winds will be south or southeasterly this evening around 10 to 15 knots with some higher gusts possible. The gust potential will decrease through out the evening. Winds will gradually become more southerly to south-southwesterly around 200 degrees by late in the TAF period around 10 knots.

Outlook . Non-VFR possible with periods of rain showers through Monday night. Non-VFR possible in northeast Ohio and northwest Pennsylvania Wednesday and Wednesday night.

MARINE. Low pressure centered over Illinois will continue to slowly move northeastward over the Great Lakes region through the beginning of the week. A warm front will move north across the lake this evening, followed by a cold front in the late overnight/early morning hours on Sunday. Southeasterly winds across Lake Erie currently will allow for gusty winds of 15 to 20 knots across the eastern basin as a result of downsloping just south of the area. Winds will veer to have a more south to southwesterly component at 10 to 15 knots, occasionally up to 20 knots, through Sunday. Highest waves will be along the northern lakeshore at 2 to 4 feet, keeping the nearshore zones at 1 to 3 feet. These conditions will persist through Monday before another cold front shifts winds to westerly at 5 to 10 knots. For the middle of the week, winds will trend more northerly as high pressure builds over the area.
