.SYNOPSIS... A low pressure system and associated cold front will move southeast across the Great Lakes today. This low will open up into a trough tonight and get absorbed into a low moving up the East Coast. A ridge will build from the northeast for Sunday and Monday. A cold front will move through the area on Tuesday.
&&
.NEAR TERM /THROUGH SUNDAY/... Some light, pre-frontal shower activity is moving through the area early this morning with only the radar returns near or over Lake Erie reaching the surface. The main front remains off to the west over southeast Michigan and lower Ontario. This front will push east over Lake Erie today and allow for more rain activity to develop as the main closed upper low slides southeast over the lake. This will allow the potential for some convective showers and even some thunder, which could move into adjacent areas of NE OH and NW PA. Overall, rainfall amounts will be light with generally less than one quarter of an inch of rain expected today over land areas. The surface low pressure system will open up into a trough tonight with the parent closed upper low drifting off to the east. This should allow for rain activity to subside tonight with the focus off to the east. Temperatures today will be status quo for areas away from the lake with upper 60s into lower 70s. For areas near Lake Erie, temperatures will remain subdued in the 60s with clouds and rain in the region. Lows tonight will fall into the 40s as clouds clear to the east.
For Sunday, the closed upper low will slightly retrograde westward and may offer some slight upper level support for the surface trough. Therefore, there could be some isolated to scattered shower activity over eastern Lake Erie and extending into NE OH and NW PA. However, with flow across the region being southeasterly to easterly, there may be some downsloping in the hills of OH/PA to mitigate rain potential over land and will just have some low PoPs but the period may just be dry with some clouds, courtesy of the moisture and lift entering the region from the east.
&&
.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/... For Sunday night into Monday, the surface trough will exit east and the pesky upper low will get absorbed into the larger low pressure system moving up the East Coast. This will allow a surface ridge to build from the northeast and enter the local area, allowing for a dry period with seasonable temperatures. On Tuesday, a cold front will approach the area from the northwest. Some warmer air will advect into the region ahead of the front and a large chunk of the area appears set to reach 70 degrees, perhaps mid to upper 70s in NW OH where drought persists. The front will cross the area later in the day on Tuesday and allow for some rain potential Tuesday night, but the lack of upper level support will make any rain activity isolated to scattered in nature.
&&
.LONG TERM /WEDNESDAY THROUGH FRIDAY/... For Wednesday and Thursday, the area will be controlled by cooler, Canadian high pressure, which will bring temperatures back toward normal, if not a touch cooler, and allow for some cooler, radiating nights on Wednesday and Thursday with frost/freeze potential. The cooler air mass will also need to be tracked for any lake effect rain, but the overall dry air mass will make that threat rather limited. The high pressure system will shift east on Friday, allowing for a warm front and return flow back into the region, which will allow for another chance for 70s, especially for the western half of the area.
&&
.AVIATION /06Z Saturday THROUGH Wednesday/... VFR across the TAF sites early this morning with mainly VFR to persist through the TAF period. Some MVFR ceilings and rain showers may accompany a cold front this morning at CLE/ERI, though confidence is low. Otherwise, any lingering sub 5kft ceilings should erode to sct by this afternoon.
Winds early this morning are south to southwest ahead of a cold front, around 5 knots. Winds will shift towards the northwest and north behind the front later this morning and afternoon, around 5 knots. Winds will then gradually favor a northeast direction by later this evening, around 5 knots.
Outlook...Mainly VFR conditions favored through Wednesday.
&&
.MARINE... South to southwest flow may approach 20 knots in the nearshore tonight, though a small craft advisory is not expected. A weak cold front crosses Lake Erie late tonight into Saturday morning with flow become northwest. There is a low chance for waterspouts on Saturday and Saturday night. Light and variable conditions on Saturday will give way to east to northeast flow through Monday night with speeds averaging around 15 knots. Wind speeds could briefly approach 20 knots Sunday afternoon into Sunday night. A weak cold front moves across the lake on Tuesday.

.CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None. MARINE...None.
