Area forecast discussion, Jun 18, 9:08 PM EDT, 1 hour 22 minutes before
Area Forecast Discussion National Weather Service Cleveland OH 908 PM EDT Sun Jun 18 2017 .SYNOPSIS... A cold front across northwest Ohio will move to the Appalachians by daybreak. An upper level trough will persist across the area into the middle of the week. High pressure will gradually build east into the region Tuesday into Wednesday. Another cold front should push into the area by Friday. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... The severe thunderstorm watch has been cleared. Will continue to keep at least a small chance of showers and thunderstorms in the forecast until the front is east of the area. At 9 PM the front seemed to be from near Sandusky southwest to near Findlay. It will until the pre-dawn hours for the front to move east of the forecast area. Will take a look at temperatures with a quick update on toward 1030 PM. No other changes for the evening update. Previous Discussion... Convergence along a prefrontal trough has moved eastward with outflow that was generated by the thunderstorms across the eastern CWA. Convergence near and ahead of the front has drifted into NW OH. This should continue to move eastward through the evening under limited instability. We will monitor it as it drifts eastward. So after some evening thunderstorms we should transition to scattered showers before drying out from west to east through sunrise. As the drier air arrives it will allow temperatures to drop lower than the last couple nights. Lows should dip into the lower to middle 60s. Coolest across the west. && .SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY NIGHT/... An upper level trough will linger across the region into the middle of the week. This as a couple ripples of jet energy pass through it. So expect to see at least some scattered showers Monday through Tuesday evening. These chances should shift eastward with the trough on Wednesday as surface high pressure moves into Ohio. There may be enough instability across the area MOnday afternoon to generate a few rumbles of thunder. It will be cooler through the short term with temperatures running near to slightly below seasonal averages. && .LONG TERM /THURSDAY THROUGH SUNDAY/... Fairly zonal upper flow shown for Thu that will transition into a LW trough that digs into the upper midwest by Sun. Think surface high pressure and lack of upper support should limit coverage of possible convection Thu but cold front slowly crossing area Fri into Sat should provide the focus for more widespread activity. Increased support from nearby upper trough will probably produce sct shra for Sun with daytime heating. Temps should warm Thu into Fri to be a little above normal then trend cooler Sat thru Sun as cold front passes. && .AVIATION /00Z Monday THROUGH Friday/... Cold front almost east of the area with ongoing convection generally east of a KCLE-KMFD line. Expect convection to decrease through the evening hours. Mainly VFR overnight however do expect some patchy fog development inland areas. Did bring fog into KMFD after 06z but for now left it out elsewhere. Monday mostly VFR however there will be a trough aloft across the area which will support convective cumulus cigs around bkn- ovc045-050 through much of the day. Could also see a few showers but again for now have left out. OUTLOOK...Non-VFR possible at times Tues thru Fri in sct shra and a few tsra. && .MARINE... SW winds 10 to 20 knots ahead of the cold front will shift a little more toward the west tonight while speeds diminish a few knots. A series of reinforcing cold fronts/troughs will move se across the lake Mon into Tue veering winds to the west, maybe WNW for a while. There may be periods where winds of 15 to 20 knots could produce near SCA conditions. High pressure will spread ne into the lake Wed to calm the winds. The high will shift off to the east by Thu to allow a warm front to lift across the lake and result in south winds of about 10 to 15 knots. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None. MARINE...None. && SYNOPSIS...Kosarik/Mullen NEAR TERM...Kosarik/Mullen SHORT TERM...Mullen LONG TERM...Adams AVIATION...TK MARINE...Adams
