Area Discussion for - Cleveland, OH
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kcle 191350 afdcle area forecast discussion national weather service cleveland oh 950 am edt Mon aug 19 2019 Synopsis A stationary front will remain west to east across the region over the next several days. A series of weak disturbances or mid level troughs will move along the front bringing on and off chances for storms through the middle of this week. The front will move southeast through the area Wednesday night. A cooler and drier weather pattern will follow for the end of the week as high pressure builds across the region. Near term through Tuesday A cold front just north of lake erie will slide south across the area this afternoon. The front will be the focusing mechanism for a few possible showers and thunderstorms during the afternoon hours. Will keep the chance pops going for today. Made some adjustments to the cloud cover in the northwest and northeast to account for clouds in place. Previous discussion... a very weak and stalled frontal boundary is located from west to east near lake erie this morning. It it ill-defined and trapped under a west to east flow in the upper levels. Another weak mid level disturbance or piece of energy will ride along the westerly flow again this afternoon across indiana into ohio and northwest pennsylvania. This small disturbance in the 500 mb flow may interact with the stalled weak surface boundary again this afternoon and develop a few scattered showers and thunderstorms with the daytime heating. Shear and thermodynamics will be weaker today and do not expect much in the way of storm organization. At this time, we do not see much in the potential for anything strong, just general scattered thunderstorms expected. Most of that diurnal convection will decrease around or after sunset this evening. We should see a fairly quiet evening and night tonight. A slightly stronger disturbance and some mid level jet energy will move across the midwest into the ohio river valley on Tuesday and Tuesday afternoon. This feature will be able to interact with the weak surface boundary and there will be better thermodynamics to work with Tuesday afternoon. Spc has the entire region in a marginal risk. We will see a little better coverage of scattered showers and thunderstorms Tuesday afternoon into the evening. A few strong to severe storms may be possible with damaging wind gusts up to 65 mph and large hail up to quarter size. Short term Tuesday night through Thursday night Tuesday night will still have some residual instability with mucape still holding around 1000 to 1500 j kg. With outflow boundaries likely present from daytime convection, scattered convection will likely still persist through the overnight period. On Wednesday, thunderstorms are expected to continue downstream a rapidly digging upper level trough. Most model guidance have temperatures in the low to mid 80s by 18z Wednesday with dew points in the upper 60s to lower 70s. MUCAPE expected to be around 1500 to 2000 j kg with 0-6 km shear of 25 to 35 knots, depending on which model guidance you look at. Because of this combination, there is a |
small chance for severe weather on Wednesday afternoon. The cold front is expected to move east across the area on Wednesday evening decreasing pops behind it. High pressure begins building in from the northwest on Thursday, bringing with it seasonably cool and dry weather. Long term Friday through Sunday Seasonably cool and dry weather continue through Friday and Saturday as high pressure continues to progress southeast across the great lakes region. As high pressure moves to the northeast, warm, southerly advection brings back seasonably normal temperatures and dew points to the area. The next real chance for precipitation is Sunday night into Monday afternoon ahead of a developing upper level trough. Aviation 12z Monday through Friday A weak surface front is located west to east across northern ohio near the lakeshore. Surface winds will be ill-defined today especially near the weak surface boundary. We will keep winds mostly light and variable today closer to the lakeshore and a light south or southwest wind for TAF sites closer to central ohio. Winds will be 5 knots or less regardless. We will expected mostlyVFR conditions for the next 24 to 30 hours. The only exception will be tol this morning with some low clouds and light fog. Ceilings have been bouncing around 300 or 400 feet and can expect that for the next few hours. There could be a few isolated or scattered showers and storms this afternoon but overall coverage is not high enough to mention in tafs at this time. Outlook... Intervals of non-vfr possible primarily with thunderstorms possible Tuesday through Wednesday. Marine Generally low impact winds and waves the next few days on lake erie. A cold front currently situated over lower michigan will slowly move south across the lake today and stall just south of the lake tonight. As low pressure develops and moves northeast into ontario, this stationary front will lift north as a warm front Tuesday afternoon. A cold front extending from the aforementioned low will move east across the lake on Wednesday afternoon allowing 10 to 15 knot northerly winds to persist through Wednesday night. With a warm lake and cold advection processes, there is a chance there could be overperforming wind speeds Wednesday night into Thursday morning. The GFS is hinting at pockets of 20+ knot of onshore flow, which would certainly bring some nearshore zones into small craft advisory condition. This will be something to watch in the next couple of days. High pressure moves east across the area on Friday with winds generally staying around 10 knots or less through the weekend.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
