Area Forecast Discussion National Weather Service Cleveland OH 333 PM EDT Mon Jul 3 2017 .SYNOPSIS... A weak cold front bisecting northern Ohio will continue south of the area this evening. High pressure will build in from the north Tuesday and Tuesday night. The high will move to New England Wednesday and allow low pressure to track northeast across Ohio on Thursday. && .NEAR TERM /THROUGH TUESDAY NIGHT/... A weak cold front is currently dropping south through the area and is near a KFDY-KCAK line mid afternoon. Showers and thunderstorms have developed from Wayne and Stark counties into Columbiana county between 2:30 and 3pm in the vicinity of the front. HRRR and NAM12 guidance show scattered showers and thunderstorms continue to develop along this line which will be drifting slowly south into evening. Will have chance pops that last thru the evening for the southern half of the area. Low temps overnight should drop well into the 60s behind the front with mid 50s inland northeast Ohio and nwrn PA. Expect clouds to decrease overnight as drier air moves in. Tuesday expect plenty of sunshine and light northeast winds 5 to 10 mph. Tuesday evening skies mostly clear. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... An area of subsidence will develop over the area Wednesday between a weak surface wave over the Ohio River and a deepening low over Missouri. Moisture from the initial wave should stay south of the area, which will keep dry conditions over the area one more day. Moisture will begin streaming into the area Wednesday afternoon with dew points creeping into the 60s. A warm front ahead of the low will expand showers into the area starting in the southwest Thursday, though there remains some discrepancy in timing. The GFS is the most aggressive with this feature and the extent of the precip shield, which could be the result of convective feedback. The northern stream energy doesn't become as well aligned in the ECMWF which is also slower with the feature. Shear remains low, with moderate to locally heavy rainfall more of a concern Thursday Night and possibly into Friday. && .LONG TERM /FRIDAY THROUGH MONDAY/... Rain chances continue into Friday under muggy conditions until the cold front moves through Friday Night. Looking at NW flow aloft and high pressure from Canada building in for Saturday and into Sunday. The airmass transition will be noticeably drier with temperatures in the 70s. This pattern looks to continue into the beginning of next week, at which time attention turns to the building ridge over the central US. && .AVIATION /18Z Monday THROUGH Saturday/... Weak cold front to drop through the area today. May tough off a few showers and thunderstorms mainly southern portion south of I30. VFR expected tonight and Tuesday. OUTLOOK...Some Non-VFR early morning fog for YNG Wednesday morning. Non-VFR conditions possible in SHRA/TSRA late Wednesday through Thursday. && .MARINE... Main threat for mariners will be chance for storms with heavy rain Thursday into Friday. High pressure over Lake Erie will continue into Wednesday. This will support a east-northeast wind around 5-10 knots for the next few days, increasing waves in the western basin. An area of low pressure over the plains will pass just south of the Lake Thursday Night followed by a cold front Friday Night. Winds ahead of and just behind the front will mix in some 15 knot or greater winds, strongest Friday Night. This will be followed by Canadian high pressure into the weekend. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None.
