Area Discussion for - Cleveland, OH
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kcle 251354 afdcle area forecast discussion national weather service cleveland oh 954 am edt Sun aug 25 2019 Synopsis High pressure across quebec and stretching across the great lakes will provide another day and a half of fair weather to the local area. Low pressure tracking from the canadian rockies east to ontario early this week will take bring a warm front north across the area Monday night and a cold front across Tuesday night. High pressure will shift across the ohio valley Wednesday into Thursday. Near term through Monday Increasing high clouds will filter the sunshine this afternoon. The eastward shift of the high, now across quebec, will bring winds around to the east southeast and the lake cloud cover will be shifting across the lake toward mi. The southeast flow will assist int drying the region with the coverage of cumulus likely less than days prior. Again guidance has been running low on expected high temperatures and have kept the temperatures for today several degrees warmer. This is similar to what we had going for today. Mid and upper 70s for most after a morning start in the 50s. Will have another night in the 50s tonight across the east, but enough of a southeast wind will keep temperatures a few degrees warmer. Monday introduces the next opportunity for a few showers across the i-75 corridor and possibly to the central highlands. Surge of deeper moisture will return with a warm front Monday afternoon night. Under this initial corridor we will have scattered showers. Less confidence in how far east these showers will make it before evening. Temperatures will generally be in the mid 70s with extensive cloud cover expected. Short term Monday night through Wednesday night A shortwave trough is expected to move northeast into our area, advecting moisture and forcing showers across the area Monday night and into Tuesday. A large scale trough is situated over the upper midwest and will work its way east on Tuesday and Wednesday with the trough axis through the lower great lakes by 00z Thursday. This will cause a deepening low over western ontario with a cold front extending through the great lakes region. A line of thunderstorms and showers are expected to develop ahead of this cold front Tuesday afternoon and move east through northern ohio Tuesday evening into the overnight hours. A cold will closely follow, allowing mostly dry air to filter in on Wednesday and Wednesday night. There may be just enough remaining moisture for lake effect rain to persist over NW pa and NE oh Wednesday night. Long term Thursday through Saturday Lake effect rain showers may still persist through the daytime hours on Thursday. A weak upper level trough is expected to move east through the area sometime on Saturday or Sunday, though there is substantial uncertainty with regard to the timing of this this feature. Precipitation is expected to develop |
downstream this wave on Friday or Saturday. Favoring the faster canadian GFS solution and have chance pops Friday night into Saturday morning. The ECMWF has a much slower solution with precipitation moving through Saturday and into Sunday. Followed primarily the ECMWF for timing through the long term which shows a cold front dropping south across the region Saturday. This could bring a shower or two to the area although models don't show a great deal of moisture with the boundary. Aside from that, high pressure will dominate the region. Highs mainly mid and upper 70s. Aviation 12z Sunday through Thursday Little change with this set of tafs. A third day in a row with high pressure controlling the local weather with only fair weather afternoon cumulus in the forecast. Flow will be more east-southeast today as the high has shifted northeast of the area. This will be a drying flow and expect fewer CU than yesterday. Winds for cle eri will tend to be northeasterly for a time this afternoon with a minor lake breeze. Some cirrus will be headed our way Sunday night. Southeast winds at eri tonight will have minor gusts to 25 knots. Outlook... NonVFR possible with scattered showers and thunderstorms Monday afternoon through Tuesday night. Marine Winds have decreased to around 10 to 15 knots and will meander between east and southeast today over the lake today. For this reason, we have allowed the small craft advisory to expire and am not anticipating needing another one today. High pressure over eastern quebec will continue to slowly move eastward and weaken as a developing low over the northern atlantic overtakes it. The eastward moving high pressure will allow winds to veer to the south Monday night into Tuesday morning. Low pressure of around 995 mb develops over western ontario by Tuesday morning, increasing the pressure gradient over the lake and allowing winds of 15 to 20 knots Monday night into Tuesday, with peak winds around 12z on Tuesday. Since it's going to be offshore flow, am not anticipating needing a small craft advisory for any of our nearshore zones. Showers and thunderstorms are expected Tuesday and into Wednesday before a cold front sweeps through late Tuesday night into Wednesday morning. Weak high pressure passes to the south, keeping winds below 15 knots through the end of the week. Cle watches warnings advisories Oh... None. Pa... None. Marine... None. Synopsis...

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. |
