Area Forecast Discussion National Weather Service Cleveland OH 136 AM EDT Mon Sep 28 2020

SYNOPSIS. A weak cold front will approach the area tonight into Monday. A second, stronger cold front will move across the area Monday night. A ridge will build in on Tuesday before another cold front moves across the area again Wednesday into Thursday.

NEAR TERM /THROUGH TODAY/. Some adjustments to timing of the precipitation in the east may be needed. Short term high resolution models are indicating some potential for isolated showers developing over the eastern half of the forecast area well ahead of the cold front. Some instability and moisture will be present during the afternoon and there appears to be an increasing threat for shower activity. Latest radar showed some shower activity waning south of the forecast area over the last few hours. This activity is what we will have to watch for the east. Minor update to temperatures across the area over the next several hours.

Previous Discussion . The cold front has reached the Toledo area this evening and mid-level cloudiness is entering the greater Northwest Ohio region. Some showers have developed immediately with this front and could lash at the Toledo area overnight and will keep a slight chance PoP. Dew points in the upper 50s to lower 60s and clouds increasing will keep low temperatures from dropping too far and will keep temperatures generally in the lower 60s.

Monday will be the first day with appreciable precipitation across the forecast area as a strong upper trough enters the region, supporting a strong surface cold front. The front will approach the Ohio/Indiana border around Noon and push east across the area during the afternoon and evening hours. Strong lift and moisture over the region will allow for widespread precipitation and have categorical PoPs across the forecast area with timing following the front. Instability will be limited ahead of the front with broken/overcast skies and some showers with the low level jet well ahead of the surface cold front, so thunder chances with this system will be slim. However, the dynamics with a strong upper jet and bulk shear values of 50 to 60 kts could allow for a marginal severe weather threat with organized showers and isolated storms with the front. Regardless of severe weather potential, synoptic winds with this front will allow for wind gusts of 25 to 35 mph during the day time hours as some of the strong jet energy mixes to the surface. Temperatures during the day on Monday will be largely dependent on the frontal timing, but areas further east will be warmer into the 70s, whereas NW Ohio will see highs achieved by Noon in the upper 60s. Cold air surges into the region quickly behind the front on Monday night and lows will drop considerably into the 40s to lower 50s across the area.

SHORT TERM /TONIGHT THROUGH WEDNESDAY NIGHT/. A deep longwave trough aloft and embedded shortwave disturbances affect our CWA through the period as the longwave trough encompasses much of central/eastern Canada and the U.S., respectively. At the surface, a lake-aggregate trough deepens over the Great Lakes as a ridge attempts to build from the Lower OH Valley Tuesday and Tuesday night. Primarily fair weather is expected. However, isolated rain showers associated with the upper-reaches of a cold front departing our CWA to the east may affect far-eastern portions of our region from daybreak through the evening on Tuesday. Afternoon highs should reach the lower to mid 60's. Overnight Tuesday night, lake effect rain showers should develop over Lake Erie and stream northeastward as cold air deepens amidst a southwesterly steering flow. Low temperatures should reach the 40's to lower 50's Tuesday night.

Surface troughing expands Wednesday as a reinforcing cold front approaches from the northwest. Primarily fair weather is expected, but a band of lake effect rain showers should continue to stream northeastward from Lake Erie. This lake effect precip should remain offshore northeast OH and northwest PA. Afternoon highs should reach the lower to mid 60's. The cold front should sweep southeastward across Lake Erie and the rest of our CWA Wednesday night, causing the steering flow of cold air to shift from southwesterly to westerly. The lake effect rain should shift southward into the primary snowbelt counties of northeast OH and northwest PA. Greater lake-induced CAPE may permit the development of lake effect thunderstorms. Outside the lake effect precip, isolated rain showers may accompany the cold frontal passage. Low temperatures should reach the 40's, but lower 50's are expected along most of the immediate shore of Lake Erie.

LONG TERM /THURSDAY THROUGH SUNDAY/. The deep longwave trough should remain entrenched over central and eastern portions of the U.S. and Canada. Embedded shortwave disturbances should affect our CWA. At the surface, a trough should linger over and near the Great Lakes. A primarily westerly to northwesterly steering flow may continue to direct lake effect rain showers and occasional thunderstorms east and perhaps southeast of Lake Erie Thursday through the upcoming weekend. Inland from the lake, wet snow may mix with the lake effect rain during the predawn hours of Saturday and Sunday mornings. Drier weather conditions are expected outside lake effect precip. Below-normal temperatures and an overall cooling trend are expected. On Thursday, daytime highs should reach the mid 50's to lower 60's. By the weekend, morning lows in the mid 30's to mid 40's and highs only in the 50's should be common.

AVIATION /06Z Monday THROUGH Friday/. A cold front was located over northwest Ohio at this time with a stronger reinforcing cold front back over Iowa that will gradually move east toward the area. The first front will for the most part wash out this morning. Showers will develop and move east along the the secondary front this afternoon and evening and this is when the best chance for the precipitation is expected. Some of the short term high resolution model data is hinting at some instability well ahead of the cold front over the eastern half of the area this afternoon. Can't rule out a stray shower or thunderstorm over the east during day time heating. But overall coverage is limited so will leave it out for now in the east. Cold front moves east of the area this evening. Moisture along the front will shift east with the front this evening and bring an end to the precipitation from west east. Ceilings and visibilities will be impacted in the rain and will drop to IFR in ceilings and MVFR visibilities. Winds will experience a slight wind shift with the cold front.

Outlook . Non-VFR possible with lingering low ceilings Tuesday and showers Wednesday through Friday.

MARINE. Southwesterly to southerly winds of about 5 to 15 knots are expected on Lake Erie through most of Monday as a high pressure ridge exits ahead of a cold front approaching from the west. Waves trend 1 to 3 feet. The cold front sweeps eastward across the lake Monday evening through Tuesday morning, causing southerly winds of about 15 to 25 knots to shift to westerly. Gusts up to about 30 knots are expected, especially behind the front. Waves build to 3 to 6 feet and a Small Craft Advisory will probably be needed.

On Tuesday through Thursday night, southwesterly to westerly winds trend about 10 to 20 knots as a trough lingers over Lake Erie. A second cold front should sweep southeastward across the lake Wednesday night and may be accompanied by enhanced winds of 20 to 25 knots. Waves trend 3 to 5 feet and additional Small Craft Advisory conditions are probable. Behind this second front, troughing still lingers over Lake Erie on Friday. Westerly to northwesterly winds of 10 to 15 knots are expected. 3 to 5 foot waves early on Friday should subside to 1 to 3 feet by the end of the day.
