Aloft, a ridge builds from the Upper Midwest as a low moves ENE'ward from the Upper OH Valley to the Gulf of Maine through 18Z/Sat. Simultaneously, at the surface, a ridge continues to affect our region as the parent high pressure center moves from WI to the Upper OH Valley and a weak cold front sweeps SE'ward from the Upper Midwest to near a CYYZ to KFWA line. VFR and fair weather are expected to persist in northern OH and NW PA through 18Z/Sat. NW'erly to NE'erly regional surface winds around 5 to 15 knots, gusting up to 20 knots at times, are expected to become light and variable around 23Z/Fri. After ~12Z/Sat, our regional surface winds are expected to become SW'erly to W'erly around 5 to 10 knots. Outlook...VFR and fair weather are expected through Monday. Periodic rain showers and thunderstorms with non-VFR are forecast this Monday night into Tuesday. && .MARINE... Northerly flow 10 to 15 knots decreases below 10 knots while becoming variable as high pressure continues to build overhead. High pressure remains overhead with offshore flow expected through Saturday. A weak cold front will sag across Lake Erie Saturday night which willallow for onshore winds 10-15 knots to return.
