Area Forecast Discussion National Weather Service Cleveland OH 258 AM EDT Sun Sep 27 2020

SYNOPSIS. High pressure over the East Coast will continue to move eastward as a cold front approaches the area Sunday night 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 MONDAY/. A surface low currently centered over northern Wisconsin is expected to continue to strengthen through the day today. As a result of the increased gradient over the area , south to southwesterly winds are expected to be sustained at 10 to 15 knots, gusting between 20 to 25 knots into the overnight hours before weakening. As the associated cold front begins to approach the area today, some low stratus clouds may impact the western counties this morning before scattering out by midday. Aside from that, overall cloudiness will increase from west to east, becoming mostly west of I-71 by sunset. No precipitation is expected today with high temperatures in the upper 70s. With increased cloudiness into the overnight hours, radiational cooling will be limited and temperatures will remain in the low 60s.

By Monday morning, a cold front should be roughly positioned along the I-71 corridor, with scattered showers impacted the western portion of the CWA. By Monday morning, winds will become calmer at 5 to 10 knots and be southwest to westerly. This cold front will move through the area into the beginning of the short term forecast period (Monday night). Opted to keep thunder out of the forecast as the front does not appear to be associated with much CAPE, however a few isolated thunderstorms cannot be ruled out. PWAT values of 1.4 to 1.6 inches across the area coupled with deep warm cloud layers at times may produce locally heavy rain at times, however with recent lack of rain and the expected movement of the system, flooding is not a major concern as of now. High temperatures on Monday will be a bit cooler in NW OH reaching on the high 60s, but will remain in the mid 70s for the remainder of the area.

SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/. Elongated upper level trough will move east over the local area Monday and Monday night. The trough will become somewhat negatively tilted as deep stacked low settles south into the Great Lakes region. A series of low pressure systems will move northeast in the mean flow along a stationary front that extends through the Great Lakes from southwest to northeast. This orientation of the stationary front will keep the forecast area in the warm sector through Monday and early Tuesday. Once the last surface low pressure system moves northeast of the area, the cold front will slide southeast across the area Tuesday. A weak surface ridge will build northeast into the region Tuesday behind the cold front. As mentioned, temperatures should remain on the mild side Monday night and Tuesday morning and then we will begin to feel the effects of the cold air advection later in the day Tuesday through Wednesday night. A narrow swatch of moisture will persist with the cold front Monday night and this should be our best shot for precipitation during this period.

LONG TERM /THURSDAY THROUGH SATURDAY/. Deep upper level low pressure system extending from James Bay through central Ontario, Canada will gradually move east to Quebec by Friday. The upper level low will then retrograde back northwest toward James Bay by Saturday morning. Upper level trough will persist over the local area during this forecast period. A reinforcing cold front will move southeast across the area Thursday night and usher in deeper and stronger cold air advection to the area. This should keep temperatures in the 50s for highs during the end of the period with lows in the 40s Thursday night to 30s by Friday night. Upper level positive vorticity advection will also take place Thursday night with limited moisture. So, will keep mention of showers across the entire area transitioning to mainly in the northeast. Lake to 850 mb temperature difference supports some conditional instability Thursday through Saturday night and flow is beginning to become better aligned to develop some lake effect rain showers during this period. Will keep mention of shower and possibly a thunderstorm threat during this period.

AVIATION /06Z Sunday THROUGH Thursday/. VFR conditions will prevail through the majority of this TAF forecast period. Hi-Res models continue to suggest a period of low stratus during the morning hours ahead of the approaching cold front this morning between 12-15Z for the western terminals. This could result in ceilings lowering to MVFR, but are not expected to become IFR and are expected to scatter out by midday. Primary concern with this period is the increasing gusty winds across the area with the approach of the strengthening low pressure. Sustained southwesterly winds of 10 to 15 knots across the area will have the potential to gust up to 20 to 25 knots through 00Z before weakening through the overnight hours on Sunday.

Outlook . Non-VFR possible with showers and thunderstorms Sunday night through Wednesday.

MARINE. Winds will continue to increase from the south-southwest early this morning on the lake and flow should be mostly offshore and will keep the threat of the highest waves beyond the 5 nautical miles from shore. Winds are expected to decrease this afternoon into tonight to around 10 to 15 knots from 15 to 25 knots this morning. A cold front will shift east across the area Monday and winds will remain on the lighter side. The flow over the lake will then shift back to southwest by Tuesday night and there is the possibility that a small craft advisory will be needed through Thursday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
