Area Forecast Discussion National Weather Service Cleveland OH 628 AM EDT Fri Sep 17 2021

SYNOPSIS. High pressure exits eastward today as a cool front approaches from the Upper Midwest and Upper Great Lakes. The front drifts southeastward across our region tonight into Saturday. Behind the front, another ridge affects our region through Sunday as the embedded high pressure center moves from the Upper Midwest toward southern Quebec.

NEAR TERM /THROUGH SATURDAY/. Southwesterly to westerly flow aloft through tonight becomes northwesterly over our CWA on Saturday. Simultaneously, a prominent shortwave trough advances from the Upper Midwest toward Labrador, while another shortwave trough eventually moves east across the Great Lakes on Saturday and is followed by high pressure aloft building from the Great Plains. At the surface, high pressure exits gradually today as a cool front approaches from the Upper Midwest and Upper Great Lakes. This front is still poised to drift southeastward across our region tonight through Saturday.

Mainly clear skies, light or calm surface winds, and residual low-level moisture have allowed patchy radiation fog and river valley steam fog to form early this morning, especially inland from ~72F Lake Erie. Fog will dissipate with daytime heating by late morning. Otherwise, daytime heating of surrounding land and a weak synoptic-scale MSLP gradient will allow a Lake Erie lake breeze to form this afternoon through early evening. Sufficient boundary layer moisture and weak to moderate SBCAPE/MLCAPE should allow isolated showers and thunderstorms to form along the lake breeze front in northeast OH and northwest PA. Late afternoon highs will range from the lower to upper 80's, with the coolest readings along the Lake Erie shore and in the higher terrain of northwest PA.

If convection forms along the Lake Erie lake breeze front, the consensus of higher-res model guidance suggests additional isolated showers and thunderstorms will impact northeast OH and northwest PA this evening through perhaps the wee hours of Saturday morning as an expanding cold pool interacts favorably with low-level vertical shear amidst weak to perhaps moderate SBCAPE/MLCAPE and marginal effective bulk shear. Otherwise, a few showers and thunderstorms are possible over/near Lake Erie during the predawn hours of Saturday morning with the approach of the aforementioned front. Overnight lows should reach the 60's. A few more showers and thunderstorms are expected along the southeastward-moving cool front on Saturday as the front encounters a moist warm sector with weak to perhaps moderate instability. Mostly cloudy skies along/near the front will gradually become mainly clear from northwest to southeast as high pressure at the surface and aloft builds behind the front. Saturday will be somewhat cooler with late afternoon highs reaching the mid 70's to lower 80's.

SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/. Amplification of an upper level ridge will take place over the eastern half of the Lower 48 states during this period. This amplification will be the result of amplification of an upper level ridge over the western United States during this time period as well. The ridge will gradually shift off the East Coast by Monday night. Meanwhile, an upper level trough will dig into the Plains states and Mississippi Valley region. Surface high pressure will build east through the Great Lakes and then northeast to Quebec. A ridge will extend southwest from the high pressure center through the Great Lakes to Texas by Sunday morning and persist through Monday. All-in-all, a return south to southwest flow will cause warm air advection to take place through much of the period. After some minimal chance showers for Saturday due to a weak cold front that will slip southeast across the area during the morning, fair weather will return with the high pressure building across the region.

LONG TERM /TUESDAY THROUGH THURSDAY/. An upper level high pressure that will be situated off the coast of Maine by Tuesday will continue to keep a return south to southwest flow of air across the area Tuesday. Surface high pressure will be nearly vertically stacked under the upper level high pressure center. Meanwhile, upper level trough over the Plains states will force a surface low pressure system to develop over the Oklahoma Panhandle and be ejected northeast toward the western Great Lakes. As the low pressure system moves northeast of the area, a cold front extending south from the low will move east across the local area Wednesday resulting in a push of the coldest air we have seen in some time. 850 mb temperatures are expected to dip down to around 1 degree C by Thursday with 1000 mb to 500 mb thicknesses dipping to around 540. Unfortunately, it looks like this cool air will stick around for a few days. Moisture associated with the cold front will move into the area and bring a threat for showers and thunderstorms; especially Wednesday. There is the possibility for some lake effect/enhanced rain showers in the northeast Thursday.

AVIATION /12Z Friday THROUGH Tuesday/. Mainly VFR expected as surface high pressure exits slowly eastward and a cool front approaches from the Upper Midwest and Upper Great Lakes. This front should begin traversing our region after 06Z/Sat, near a KMNN, OH/KFKL, PA line by 12Z/Sat, and be accompanied by a swath of ceilings primarily near 5kft AGL. Regional surface winds trend calm or light and variable ahead of the front. However, a lake breeze of about 5 to 10 knots should develop along and near the Lake Erie shore this afternoon through early evening. The lake breeze will affect KCLE and KERI with northwesterly winds veering to northeasterly with time. Behind the cool front, westerly to northwesterly winds of 5 to 10 knots are expected.

Patchy fog has developed this morning, especially inland from Lake Erie. Brief MVFR to perhaps LIFR should accompany the fog before it dissipates via daytime heating by 14Z/Fri. Isolated showers and thunderstorms are possible along the lake breeze front in northeast OH/northwest PA and along the aforementioned cool front. Brief MVFR to IFR may accompany any shower or storm.

Outlook . Non-VFR possible with isolated showers and thunderstorms on Saturday. Isolated to scattered showers and thunderstorms with non-VFR possible this Monday through Tuesday.

MARINE. Generally quiet weather conditions on the lake through the next 5 days and not expecting any headlines at this time. Flow will be quite variable during the period but remain around 12 knots or less. A weak cold front will slide south across the lake Saturday but high pressure will become the dominant weather feature through Tuesday as it moves through the Great Lakes up into Quebec. A ridge will extend southwest from the high across the Great Lakes through the second half of this forecast period.
