Area Forecast Discussion National Weather Service Cleveland OH 426 PM EDT Thu Oct 21 2021

SYNOPSIS. Cold front located from central Lake Erie to Mount Gilead late this afternoon will continue to move eastward, reaching the Ohio Pennsylvania border around sunset. A trough will then linger through the weekend. Another low pressure system will approach the area on Monday.

NEAR TERM /THROUGH FRIDAY NIGHT/. A cold front was located from central Lake Erie to Mount Gilead late this afternoon. This boundary will continue to move eastward, reaching the Ohio Pennsylvania border around sunset. These storms will have a chance of being surface based with the lift being enhanced by a 50-60 knot 7H jet. If storms can grow to a sufficient depth they could bring some of the stronger wind to the surface.

As the cold front passes a westerly wind will become gusty and continue into the overnight hours. Strongest winds look to be during the evening and along the lakeshore through the overnight. As the cold advection increases in the wake of the cold front we will see an increase in showers off of the lake. Best chances for these showers will from around 11 pm through 5 am. It will be cooler tonight with lows in the 40's to around 50.

Clouds should decrease across NW OH Friday morning while lake effect cloud cover covers the eastern half of the CWA. Scattered showers are expected to flow off the lake through the day, especially from the Mid-Ohio region to the OH/PA border. It will be much cooler on Friday with highs in the lower to mid 50's. However a few spots across NW PA may remain in the upper 40's.

High pressure will ridge northward into the region from the south Friday night. However an upper level trough is still located over the central Great Lakes. This combined with cooler air flowing over the Great Lakes should keep skies on the cloudy side. there could be a few showers across NE OH into NW PA but believe most will remain over the lake. Temperatures will be on the cool side with lows ranging from the upper 30's to mid 40's.

SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/. The upper level trough will pivot east across the area on Saturday. Although the surface reflection will be weak, westerly low level flow will develop on Lake Erie and lake effect rain showers are expected to develop. The passage of the upper trough will provide both moisture and support and raised pops to likely for the lakeshore counties east of Cleveland. Moisture at 700mb strips away by 03Z and coverage of showers will decrease through the overnight hours.

A break is expected between systems on Saturday night with strong moisture advection and isentropic ascent bringing chances of rain back to the area on Sunday. It will likely take until Sunday afternoon for rain to fill back in across NW Ohio.

LONG TERM /MONDAY THROUGH THURSDAY/. Low pressure will move east across the Upper Ohio Valley on Monday. The 12Z ECMWF has come into better agreement with the other long range models on Monday, with the system pulling away to the east on Tuesday. We can expect a brief break in precipitation in the Tuesday to Wednesday time frame before the next strong trough approaches from the west on Wednesday.

AVIATION /18Z Thursday THROUGH Tuesday/. MVFR/IFR showers are occurring across northeast OH into NW PA. This round of showers and isolated thunderstorms will move eastward through 20Z. Attention then shifts westward to a cold front that is located from The Islands to east of KFDY. Showers and thunderstorms along this boundary should be a bit strong with gusty winds the primary threat. MVFR and brief IFR conditions are expected with this line of showers/thunderstorms. Southwest winds become west in the wake of the cold front and become gusty. Gusts may reach 30 knots at times into the evening. Also in the wake of the cold front we expect to see a period of MVFR ceilings. KMFD area may see some IFR at times, especially overnight if the lake effect showers develop. These lake effect showers will impact much of the eastern half of northern OH into NW PA overnight. Scattered showers and the MVFR conditions will continue into Friday afternoon.

Outlook . Periods of Non-VFR Friday afternoon through Sunday with lower ceilings and scattered showers. Non-VFR possible again on Monday in rain and lower ceilings.

MARINE. A strong cold front is located across western Lake Erie with an abrupt wind shift to the west and eventually north behind the front. Winds behind the front will increase to 20-25 knots with gusts as high as 35 knots this evening. Small Craft Advisories remain in effect for all nearshore waters for tonight. The cold front will exit to the southeast on Friday with winds decreasing fairly quickly as high pressure builds into the Upper Great Lakes. Generally good marine conditions will continue through the weekend.

The next system will approach the Great Lakes region from the Plains Sunday night into Monday. Easterly winds will increase to 20-25 knots and Small Craft Advisories will likely be needed into Tuesday with high winds and waves. This will also result in rising water levels on the western basin of Lake Erie. Low pressure is expected to pass south of Lake Erie on Tuesday then depart to the east Tuesday night.
