Area Discussion for - Cleveland, OH
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kcle 190155 afdcle area forecast discussion national weather service cleveland oh 955 pm edt Thu jul 18 2019 Synopsis A trough of low pressure will move east across the area this evening. A ridge of high pressure will build northeast over the eastern united states and linger through Saturday night. A cold front will move south across the area Sunday. High pressure will build east out of the middle mississippi valley region Tuesday to the ohio valley by Wednesday. Near term through Friday night All showers over the forecast area have fizzled this evening and much of the area should be dry for the overnight. Watching some showers in northern lower michigan slide southeast and may allow for a sprinkle late along the lakeshore of NE oh NW pa, but will leave slight chance pops. A widespread deck of clouds around 20k ft will leave the area party to mostly cloudy, keeping temperatures warm overnight. Previous discussion... a potent little upper level shortwave trough will move east across the local area this afternoon and evening. This feature has a positive vorticity maximum associated with it along with a reflection to the surface as a trough of low pressure. The combination of the weather features will support the line of storms and will advance them from west to east across the area. Receiving some good wind gusts with some of the bowing segments. Locally heavy rain is occurring with the thunderstorms as they move through the area. Areas in the east took some time to destabilize due to the extensive cloud cover over that area this morning. There have been a few cells trying to pop-up over the east with little success deeper in the ridge and little upper level support downstream. The big story is the heat and humidity. Southwest flow will develop with strong warm air advection and advancing high dewpoints into the forecast area. Looking at highs tomorrow in the lower to middle 90s across the area and dewpoints rising into the lower to middle 70s. This should push heat index values well above 105; especially in the western portions of the area. Slightly lower heat index values expected over the eastern half of the area. The warm front will lift north across the area tonight and extend southeast across the northeast snowbelt Friday afternoon. Another shortwave trough and associated moisture will move southeast along the warm front by afternoon and evening and will likely kick off another round of showers and thunderstorms. So, will introduce a round in the northeast tomorrow afternoon and evening. Due to instability and being along the warm front, can't rule out a few severe thunderstorms so will have to monitor once again. Friday night will be quite warm and muggy and would not be surprised some of the cities with high potential for heat island effects will keep low temperatures in the lower 80s. Tried to highlight those areas in the grids. So, all in all, it is going to be hot and muggy. Stay cool! Short term Saturday through Sunday night Still hot and muggy on Saturday. Ohio counties will be under the second day of excessive heat warnings. Northwest pa may be just under the threshold and keep heat indices under triple digits. Precip will be hard to come by Saturday with the ridge firmly in place for much of the day. Saturday night though those chances begin to increase from north to south as a cold front sinks south from the central great lakes. Will still have another very warm night with lows in the mid upper 70s. Sunday's highs will be a step down with clouds precip around, but still humid. Frontal timing still has some wiggle room to it, but by Monday, temperatures and humidity will be |
back toward seasonal averages. Long term Monday through Thursday Much of next week we will be under the influence of an upper trough and northwest flow. The surface high from the central great lakes will build to the ohio valley. This will leave us with limited shower chances. A sharpening of the trough may bring some of those chances to the area by the Wednesday Thursday time frame. Temperatures will be seaonable through the period. Aviation 00z Friday through Tuesday Convective activity from earlier this afternoon has greatly diminished as rain has hit a dry and stable air mass. Will have just some vicinity shower mentions at the eastern TAF sites for the next couple hours but rain chances have greatly decreased. Mid-to-high clouds will linger overnight and should abate fog development over the region. High pressure building into the region will keep the area mostly dry with just some diurnal cumulus on Friday. The atmosphere has a chance to mix fairly well on Friday afternoon and could see winds gust to 20 to 25 knots across the region, out of the southwest. Outlook... Non-vfr possible in showers and thunderstorms Friday evening and again Saturday night through Monday. Marine Showers thunderstorms will be in the vicinity of the lake this evening and overnight with complexes in the area. The background flow will be southwesterly both Friday and Saturday with afternoon onshore components, but any thunderstorms would disrupt that flow for a time. Flow by mid late afternoon may be strong enough to be borderline for a small craft advisory off of erie, but confidence is not high enough to hoist the advisory. Similar situation for Saturday. Saturday night a cold front will sink south across the lake. A secondary trough will cross on Monday night. High pressure will build across the central lakes early week through mid week. The north flow on Monday will be strong enough for a least a chop on the lake. Climate It will be hot over the next 3 days but most of the records will be tough to reach. Here is a list of the record highs and the warmest minimum temperature today through Saturday.
