Area Forecast Discussion National Weather Service Cleveland OH 310 PM EDT Sat Apr 15 2017 .SYNOPSIS... A warm front along the south shore of Lake Erie will move northeast of the area this evening. Low pressure over the Plains will move across the central Great Lakes late tonight and early Sunday. A cold front trailing the low will move across the local area late Sunday. High pressure will build over the region from the north Sunday night and Monday. A pair of systems will cross the region later next week. && .NEAR TERM /THROUGH TONIGHT/... Most of the shower activity has moved into NE OH and NW PA as the warm front continues to try to move out over the lake. Temps at CLE have shot into the 80s so the front is definitely through here. Have noticed some new development over the western basin. Can't believe this activity will sustain itself very long given the cool water temps. Will however go with a leftover weather mention to account for the current activity. May get rid of this mention if the activity falls apart the next hour. The evening should be pleasant most areas albeit a little breezy. Have backed off on precip chances overnight from the earlier forecast. New guidance coming including the latest SREF suggests only the NW corner of the area has a legitimate shot for precip before daybreak. Clouds will increase again later tonight. Have stayed to the warm side of guidance for lows. && .SHORT TERM /SUNDAY THROUGH TUESDAY NIGHT/... Precip will be ongoing at the onset of the period in the west and will spread east across the rest of the area during the day Sunday as a cold front advances from the northwest. Surface dewpoints are now expected to surge into the upper 50s if not a tad higher. At the same time strong westerlies are expected in mid levels. Even with marginal instability with CAPES mainly less than 500 J/KG would not have been surprised to see the marginal risk bumped up to slight. Hopefully the precip will reach eastern areas by late morning which would help limit the severe weather potential at the southeast end of the area. Main concern for severe weather would be from damaging straight line winds. As it stands will need high precip chances all areas through about 21z. After that the front will move off to the southeast and the northern end of the area will begin to dry out. By 03z Monday the entire area should be dry. High pressure will then build in for the start of the new workweek. Expect skies to become partly cloudy by early Monday. Temps will return to seasonable values for a day before warming again on Tuesday as the high slides off to the east allowing southerly flow to return. Will maintain dry weather through Tuesday night but need precip chances overnight as another frontal system approaches from the west. Have generally trended warmer than guidance for highs. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... Upper level pattern trying to become more zonal across the lower 48 states by mid week. Weak perturbations moving east across the area triggering weak surface low pressure systems. This will wind up being an active weather pattern during the extended periods. Initially, mid week storm system will be moisture starved as it does not tap into available moisture from the Gulf of Mexico. Next low making an attempt to develop in the southern stream will lift northeast and have a better shot at tapping into the Gulf moisture. Weak warm air advection and moisture advection will take place Saturday and gradually increase into Sunday. Will stick with the likely pops for Wednesday and Wednesday night even though current thinking is that QPF values should be on the low side. Weak ridging takes place Thursday into Friday ahead of the next storm system. Warm front lifts north to central Ohio and will struggle to get into the forecast area and may hold off until early next week. Since true warm air mass does not really reach the forecast area, will keep temperatures just above normal through the period. && .AVIATION /18Z Saturday THROUGH Thursday/... A warm front will continue to lift northeast of the area early this afternoon. Some showers and thunderstorms will scoot northeast and affect the Akron-Canton and Youngstown terminals. Otherwise, just some high and mid level clouds expected the rest of the evening into tonight. Clouds advance in from the west with the cold front. Some thunderstorms are possible well ahead of the cold front. Not expecting the cold front to arrive until after 18Z in the afternoon. Ceilings lower to around 1500 feet ahead of the cold front. OUTLOOK...Non-VFR possible Wednesday night. && .MARINE... Winds are increasing out of the southwest and 15 to 25 knots over land and expect them to increase this evening over the waster. The stronger winds will not arrive until tomorrow morning just ahead of the cold front. Will hold off on issuing any small craft advisories at this time. Winds should keep highest waves just outside of the nearshore waters. May need to hoist the advisory tomorrow morning ahead of the cold front. After cold frontal passage Sunday afternoon, winds are expected to diminish and become northwesterly. Low pressure will approach the local area Wednesday and will cause winds to increase once again. May need small craft advisories at that time. Once low moves by to the east, winds diminish. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None.
