Area Forecast Discussion National Weather Service Cleveland OH 759 PM EDT Wed Jun 19 2024

Upper level ridge remains in place through this week. A weak cold front sags southward into northern Ohio and northwestern Pennsylvania Thursday before lifting back northward as a warm front Friday. Low pressure system arrives by the end of the weekend.

8:00 PM Update: Modest convergence over Northwest OH has led to a few strong to severe, slow-moving thunderstorms this evening. Isolated damaging winds and locally heavy rain are the main concerns.
Activity will gradually subside by later this evening. No major changes were needed with this update.

Previous Discussion: Unseasonably warm and moist environment continues as a ridge of high pressure remains draped over the region. This air mass has allowed for another day of strong diurnal heating leading to MLCAPE values to rise to 2500+ J/kg and pop up thunderstorms to develop along the Indiana/Ohio border this afternoon. Primary concern as these storms build east into Northwest and North Central Ohio remains to be damaging wind gusts, though enhanced shear this afternoon may lead to instances of hail and/or a tornado. As with convection this past week, expect for thunderstorms to diminish in intensity and coverage this evening as we lose daytime heating.

The ridge sinks south as a weak cold front enters the region from the north. We won't see much relief from the heat and convection as the front sags south of Lake Erie on Thursday. Still well above normal with high temperatures rising into the upper 80s to lower 90s accompanied by dew points near 70 degrees. Anticipate for scattered thunderstorms to develop along the cold front Thursday afternoon. Overnight lows tonight and Thursday night will settle in the upper 60s to lower 70s.

Upper ridge retrogrades to the west over the Mississippi Valley by Friday. The weak frontal boundary is expected to have stalled across inland areas with a light northerly flow across most of the area.
Locations downwind of Lake Erie in NE Ohio and NW Pennsylvania will see temperatures drop back into the 80s while inland areas remain in the low 90 to mid 90s. May be able to consider dropping a few counties in our northeastern area from the Heat Advisory but will probably be needed again by Saturday so will hold off on any changes at this time.

Moderate instability will remain along the stalled boundary on Friday and scattered thunderstorms are possible again. A limiting factor will be if the boundary pushes south of the area or if dewpoints drop off more than expected. The boundary pushes back north as a warm front on Saturday ahead of low pressure moving into the Upper Great Lakes. Heat indices rebound into the 95-100 degree range for all areas although with a little more mixing and lower humidity. Chance of thunderstorms should be a little lower on Saturday except perhaps if a lake breeze develops in NE Ohio and NW Pennsylvania.

Low pressure will pass north of Lake Huron on Sunday ahead of a trough dropping into the Upper Midwest and Great Lakes. Showers and thunderstorms are expected to develop ahead and along the cold front that is forecast to move through the area during peak heating. While the instability may not be as high as some of the previous days this week, forcing along the front will be better and would expect some potential for strong to severe thunderstorms.

Monday does bring some relief from the heat as high pressure builds into the Great Lakes and humidity drops off. The respite is pretty short lived as some amplification of the upper level ridge occurs on Tuesday. The ridge axis is positioned over the Plains through the middle of next week and a lower confidence aspect of the forecast is if some more organized complex of thunderstorms rounds the ridge and approaches the local area. The GFS and Canadian both show something passing near but just west of our area Tuesday into Wednesday which is more realistically where the higher instability will be located.

AVIATION /00Z Thursday THROUGH Monday/
Scattered convection in the vicinity of TOL will dissipate by later this evening. Other terminals appear unlikely to be impacted, though will keep an eye on FDY and perhaps MFD and CLE if outflows from storms over NW Ohio can lead to propagation farther south/southeast over the next couple of hours before nocturnal stabilization sets in more. Low odds overall outside of TOL and FDY. Not expecting more than isolated to widely scattered activity Thursday afternoon with greatest odds at TOL along with perhaps CLE and ERI. Confidence too low to include any mentions yet, but it's certainly possible future cycles will need to include. Some fog is possible tonight given light winds and moist airmass, though impacts to TAF sites will generally be limited. Hit it hardest at TOL due to heavy rain earlier this evening. Also maintained some MVFR BR at YNG.

Light and variable winds tonight turn light out of the south- southwest on Thursday. Lake breeze will likely flip ERI and possibly CLE out of a more northerly direction for a few hours Thursday afternoon.

Outlook...Isolated to scattered thunderstorms and non-VFR conditions are possible again Friday afternoon. More organized thunderstorms possible Sunday afternoon.

Good marine conditions with winds of 10 knots or less will continue through Friday. The main concern will be gusty winds associated with any thunderstorms that develop on the lake which could exceed 40 knots. Southwest winds increase to around 10 knots Saturday and 10 to 20 knots by Sunday ahead of the front, shifting to west behind the front later Sunday. Waves build to 2 to 4 feet across the mid- section of the lake and will monitor for any strengthening for possible Small Craft Advisory conditions. Onshore winds of 10 to 15 knots will continue on Monday as high pressure builds over the Central Great Lakes.

A prolonged stretch of hot weather is expected this week.
Temperatures are forecast to approach or exceed record highs on several days. The records for Wednesday, June 19 to Friday, June 21 are listed below for our official climate sites.
