.NEAR TERM /THROUGH SUNDAY/... We have some beautiful weather in the forecast this weekend and for the end of September. An analysis of the upper level weather pattern shows a very slow moving mid level trough over the Southeastern U.S. and a slight upper level ridge over the the Great Lakes this morning. The main westerlies or steering flow remains locked in place across southern Canada. The mid/upper level trough over the southeastern U.S. will slowly weaken and open up as a wave as it moves towards the Carolinas and Mid- Atlantic Coast today into Sunday. An upper level ridge will over the Central Plains and Midwest will move eastward into the Ohio Valley and lower Great Lakes later today into Sunday. This upper level ridge will dominate our weather pattern and bring very nice conditions this weekend into early next week.
We are seeing mostly clear skies this morning to start off our Saturday morning and expect plenty of sunshine all day today. There will be some high level clouds or cirrus drifting through our eastern Ohio and northwest Pennsylvania skies today. But overall mostly sunny to partly cloudy skies will be around today along with warmer temperatures this afternoon. High temps will range from the upper 70s to lower 80s areawide. Tonight will be more of the same with clear skies and overnight temps back down in the lower to middle/upper 50s. The weather on Sunday will feel a little more like Summer than Fall across the region with Sunny skies and afternoon temperatures climbing into the lower and middle 80s.

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/... An elongated upper level ridge will continue to remain over the Ohio Valley and Great Lakes region for early this week. At the surface, there is also a weak area of high pressure over the region that will keep winds light from the east or northeast around 5 mph. Sunny skies will continue on Monday and temperatures back in the upper 70s to lower 80s for afternoon highs. By Tuesday, the center of the upper level ridge or "dome of very nice weather" will be near the Chicago area and an upper level trough develops towards far eastern Canada and far northern New England region. A weak, dry cold front will drop southward across the Great Lakes on Tuesday. The only weather that we will see from this frontal passage is an uptick breezy or gusty northeasterly winds later in the day. More sunshine will be around Tuesday with high temps back in the upper 70s to lower 80s.

.LONG TERM /WEDNESDAY THROUGH FRIDAY/... A strong Canadian surface high pressure system will build across the Great Lakes into the Northeast U.S. on Wednesday and remain over the region through Friday. Winds will be a little breezy and gusty at times from the East-Northeast 10 to 20 mph on Wednesday, especially areas near the lakeshore. Temperatures will also be cooler and closer to seasonable averages Wednesday through the end of the week. Afternoon high temps will range from the middle 60s to middle 70s. The cooler weather will be more noticeable at night and early morning with overnight temps dropping into the 40s areawide. The forecast will continue to be dry with more measurable rainfall expected through the end of next week.

.AVIATION /18Z Saturday THROUGH Thursday/... VFR is observed areawide with mostly sunny/clear skies, and is generally expected to continue through the TAF period. Patchy fog may be possible in east-central Ohio or Northwest Pennsylvania but have not added any visibility restrictions to any TAF sites. Winds will be light and variable, becoming light and out of the northwest during the day Sunday.
Outlook...Mainly VFR conditions are expected through Thursday.

.MARINE... Calm marine conditions with variable flow and winds 10 knots or less are anticipated as high pressure maintains influence over Lake Erie through Monday. Northeast winds will slowly begin to increase throughout the day Tuesday as Canadian high pressure builds south into the region and a tropical system churns off the East Coast. Winds will increase to 15 to 25 knots late Tuesday night and possibly increase to 25 to 30 knots on Wednesday. Marine headlines will likely be needed late Tuesday through Wednesday.
