h1. Toledo weather sun aug 23 2015 link fxus61 kcle 231320 afdcle area forecast discussion national weather service cleveland oh 920 am edt sun aug 23 2015 synopsis... a cold front will move east across the area today. high pressure will build east into the region tonight. low pressure will move southeast into the northern great lakes region and force a trough of low pressure southeast across the region tuesday. the trough will remain persistent through thursday morning as high pressure gradually builds east toward the area thursday into friday. && near term /until 6 pm this evening/... update...made several changes to clouds and pops through tonight to attempt improve on timing and collaboration. also tapered pops after midnight. capes fairly decent through the evening and into the night but would expect some diurnal decrease in coverage with best forcing north of the region so lowered thunder chances (wording) after midnight. also looked out through the remainder of the short term and chose to increase general cloud cover across the region after tuesday morning as the upper low drops southeast across the lakes and encroaches into the area. previous discussion... cold front is progged to move east across the area today. moisture with the front is not all that extensive and may limit the amount of showers and thunderstorms we get through the day. qpf amounts should be light but i think we should measure at all locations. that is why i am leaning in the direction of likely pops across the entire area. leading edge of precipitation should not arrive into the western portions of the forecast area until this afternoon. activity over indiana at this time is struggling to make eastward progress in the drier air. latest spc outlook indicates extreme western portions of the forecast area in a marginal risk area for severe weather. rest of the forecast area remains in a general area for thunderstorms. warm air advection and sunshine ahead of the front should help push temperatures up into the 80s across the forecast area today. && short term /6 pm this evening through wednesday night/... the beginning of the downward slide will begin late tonight as an upper level low pressure system moves southeast toward the area. this overall pattern is indicative of a winter pattern as cold air aloft and cyclonic flow over the forecast area will persist for a lengthy period. hopefully...this is not a telltale sign of what is to come for this winter. i would hate to get stuck in a pattern like this so soon. meanwhile...as surface high pressure tries to build east into the area behind the cold front...surface trough of low pressure will move southeast toward the area on monday and tuesday. this feature along with the cyclonic flow will help to get the flow to become well aligned up the lake to produce some lake effect clouds and rain showers over the northeast portions of the forecast area. rest of the forecast area should be primarily dry through this forecast period. unfortunately...with the cool air advection taking place...it is going to feel more like a day in late september rather than late august. gfs model appears to be on target with timing of the cold front and clouds so will be leaning in that direction this morning. temperatures will be on a gradual decline with low temperatures falling into the 50s over the next several periods and highs in the 70s and then lower 70s. keep in mind this is still august so any sun will help boost temperatures fairly rapidly. && long term /thursday through saturday/... the models are a little slower at lifting out the deep trough aloft in the middle of the week. some of the guidance shows one last short wave diving into the trough wednesday night into thursday and will keep a small chance of showers across extreme northeast ohio and northwest pennsylvania on thursday. most of the area should be dry but cool on thursday. the surface high should be overhead by friday. after a cool start... we should see temperatures make progress back toward normal. will forecast highs mostly in the mid and upper 70s friday. not as much confidence by the weekend. the ecmwf and gem focus most of the active weather in the middle of the country where a short wave is progged to cut off. the gfs is more zonal with several weak short waves riding over the top of the ridge. moisture will be limited. heights will likely be relatively high and the atmosphere should remain relatively stable. unless the wave in the middle of the country is more progressive than advertised...do not see enough of a trigger to include showers in the forecast for now. && aviation /12z sunday through thursday/... vfr conditions will continue until a cold front approaches late this afternoon/evening. a scattered to broken line of showers and thunderstorms is expected with the frontal passage across northwest ohio late this afternoon or early this evening and early tonight for northeast ohio and northwest pennsylvania. quick clearing is expected behind the front tonight. vfr conditions will continue into monday. outlook...non vfr possible for keri tuesday and the snowbelt of ne oh/nw pa wednesday. && marine... winds on lake erie are gradually veering more from the south and speeds are relatively light and that will continue to be the case today ahead of a cold front. the gradient should remain weak and winds will likely not pick up much until the actual frontal passage. in fact...on onshore flow will likely develop today on the east half of the lake. the cold front should cross the western basin this evening and move east across the lake tonight. showers and thunderstorms will accompany the front although the showers/storms may remain somewhat scattered. the overall weather pattern will become almost winter like this week as a deep trough develops aloft and brisk southwest flow becomes more west to northwest on the lake. a small craft advisory will be needed...perhaps starting as early as monday and likely lasting through mid week...especially on the east half of the lake. && cle watches/warnings/advisories... oh...none. pa...none. marine...none.
