Area Forecast Discussion National Weather Service Cleveland OH 400 PM EDT Thu Oct 28 2021

SYNOPSIS. Low pressure over the Middle Mississippi Valley will slowly track into the Ohio Valley tonight through Saturday before exiting to the east Saturday night into Sunday. A cold front will move east across the area Sunday night into Monday.

NEAR TERM /THROUGH FRIDAY NIGHT/. The near term period will be influenced by a robust, vertically-stacked low pressure system moving east-northeast from the Middle Mississippi Valley into the Ohio and Tennessee valleys. Showers are already inching north into the western zones and expect stratiform rain to spread from southwest to northeast across the area overnight tonight into Friday morning, with rain continuing through Friday night. Left thunder out of the forecast since we will stay on the northern side and there will be little or no instability across our area. The rain should dissipate to showers in at least the western half of the area as the the low begins to inch eastward Friday evening, but maintained broad high-end chance to likely PoPs since there's still uncertainty in when the stratiform rain transitions to showers. It's possible that PoPs may be adjusted and decreased for Friday night as confidence increases.

Rainfall may become enhanced and moderate to heavy at times as a low-level jet possibly develops ahead of the low and moisture wraps into our area tonight through Friday afternoon. Although rainfall totals should generally be around an inch, many spots are still saturated from recently heavy rainfall and a few rivers in the western part of our CWA are still elevated, so will need to monitor potential for localized flooding, primarily in low-lying and poor drainage areas that have seen heavy rainfall in the last few weeks. The best chance of flooding will lie to the east of I-71 where FFG is lower and WPC has included this area in a day 2 marginal risk for excessive rainfall.

The pressure gradient will tighten ahead of the low tonight through Friday, allowing easterly to northeasterly winds to increase primarily along the lakeshore. It will be quite blustery with sustained winds of 15 to 25 mph with gusts up to 35 mph along the immediate lakeshore Friday morning and afternoon. The strong easterly to northeasterly flow will pose a threat for lakeshore flooding along the shore of our western counties. See marine discussion below for details on the Lakeshore Flood Watch.

Extensive cloud cover will prevent significant diurnal changes in temperatures over the next 24 hours, with lows falling into the upper 40s to lower 50s tonight and likely only rising a few degrees into the mid to upper 50s on Friday. Friday night's lows should fall into the mid to upper 40s.

SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/. The large upper level trough and low pressure system will continue to slowly move east from the Upper Ohio River Valley into the Northeast Region Saturday into Sunday. We will be on the backside of the exiting surface low pressure over western Pennsylvania on Saturday. We will have a brisk northerly surface flow with scattered rain showers likely for much of the day Saturday. Widespread rain showers will gradually become more Lake Effect rain showers for the favored areas of the Snowbelt Saturday night and wrap up by Sunday morning. Afternoon temperatures will be 50s and overnight lows in the 40s. Clouds will slowly begin to break up over northwest and north central Ohio by Sunday afternoon. Temperatures could climb up to 60 on Sunday over northwest Ohio where a little sunshine breaks out. Where skies clear out Sunday night, temperatures will dip down into the upper 30s across central Ohio into northwest Ohio. Elsewhere, lake effect clouds will hold temperatures in the 40s Sunday night.

LONG TERM /MONDAY THROUGH WEDNESDAY/. A large upper level trough begins to develop and take shape over southern Canada into the northern U.S. early next week. A dry and "quiet" cold front will move through the region on Monday. This frontal passage will start our cooling trend for the rest of the week. High temps on Monday will try to reach the lower to middle 50s before temperatures level off with cold air advection. Another reinforcing cold front will move through on Tuesday. This cold front may have a better chance to bring scattered showers. The upper level trough may try to sharpen up by the middle of next week. There is some uncertainty on how where exactly this upper level trough becomes positioned and how a surface low pressure system tracks from the Mississippi River Valley region into the eastern U.S. We will keep the forecast open ended with the mention of colder weather for later next week and the chance for rain showers and possibly wet snow showers towards the end of the long term forecast.

AVIATION /18Z Thursday THROUGH Tuesday/. VFR conditions are present across the area this afternoon, but expect conditions to deteriorate from southwest to northeast this evening as low pressure approaches from the southwest. The low will spread stratiform precipitation northeast into the area and rain (moderate to heavy at times) will continue through the remainder of the TAF period. Expect MVFR to IFR ceilings and visibilities to develop with the rain at southwestern terminals after around 03Z, spreading northeast to KERI by 12Z Friday morning. There may be brief periods of improvement Friday morning, but not confident enough to include in this update.

Winds will generally be easterly at 8 to 14 knots and a few high-elevation spots and nearshore terminals may gust to 20 knots this afternoon. Winds will become northeasterly tonight and increase to 10 to 15 knots with gusts to at least 20 to 25 knots along the lakeshore.

Outlook . Non-VFR expected with periods of rain Friday afternoon through Saturday night. A transition to lake effect showers is expected Sunday through early Monday.

MARINE. The current Small Craft Advisories for the western basin of Lake Erie look good and no changes are needed at this time. However, additional SCA will likely be needed tomorrow as winds and waves pick up for the rest of the nearshore waters east of Avon Point. We have issued a Lakeshore Flood watch for lakeshore areas of the western basin of the lake from this evening through Saturday morning. Easterly to northeasterly winds will remain elevated for a long duration of time now through Saturday. There may be a lull or short time window overnight which the winds may turn slightly southeasterly. If so, the winds will quickly change back from the east-northeast by Friday morning and increase 20 to 30 knots with gusts over 35 knots. We could see low end Gales reached on Friday or Friday evening. There is some uncertainty at this time and have refrained from issuing a Gale Watch. We will continue to monitor the potential for gales. on Friday into Friday night, waves as large as 6 to 11 feet are expected and will be largest in the central basin.

On Saturday and Sunday, the low will continue to weak and slowly pull away from the lake. Northeasterly winds will shift from the northwest or westerly around 10 to 20 knots late Saturday into Sunday. Small Craft Advisory conditions may persist in the nearshore waters of the central and eastern basins this weekend. Winds will east 10 to 15 knots over the lake early next week and waves should relax as well.
