The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Cleveland, OH wrote its last area forecast discussion before this special weather statement went out at Jul 30, 4:17 PM EDT, 2 hours 32 minutes earlier.
Area forecast discussion, Jul 30, 4:17 PM EDT, 2 hours 32 minutes before
Area Forecast Discussion National Weather Service Cleveland OH 417 PM EDT Tue Jul 30 2019 .SYNOPSIS... A cold front will move across the area through the overnight. High pressure will then build over the region by Wednesday evening then persist into the weekend. && .NEAR TERM /THROUGH WEDNESDAY NIGHT/... A cold front will continue to move across Ontario and Michigan through the evening but it will slow as it moves across the southern/southeastern CWA. Starting to see some dry air move into the region with it beginning to impact the current convection. POP's may end up being a bit too high this evening but dont want to get too aggressive yet. So expect to see the current showers/thunderstorms move southeast with the initial wind shift. Will then see what can hold together under the upper level trough as it interacts with the cold front. Isolated/scattered coverage is expected through the overnight. May even see a few showers linger through the day on Wednesday across the southeastern CWA. High pressure should take control of the region by Wednesday evening with dry conditions anticipated. It will be cooler tonight with lows in the lower to mid 60s. Highs on Wednesday will range from the mid 70s to around 80. Even cooler Wednesday night with the dry air across the entire region. Lows should dip the the 50s away from the lake. && .SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/... We begin our short term period with an amplified positive PNA pattern. The upper level ridge over the southwest CONUS isn't expected to go anywhere soon. High pressure over the Great Lakes will continue to expand and move eastward on Thursday and Friday becoming less defined by Friday night as the pressure gradient significantly weakens. Much drier air is expected to be in place and with no upper level forcing moving through our area, precipitation is not expected. Temperatures should remain near normal with high temperatures generally in the low 80s. && .LONG TERM /SATURDAY THROUGH TUESDAY/... Not much changes on Saturday as the large scale pattern doesn't change much. Dry weather should continue with temperatures relatively similar to Friday with it being a couple degrees warmer in areas such as Toledo and Findlay. The GFS has a weak shortwave moving southeast through the upper level northwesterly flow on Sunday. This may produce some scattered showers and thunderstorms on Sunday and thus have a slight chance for most of the day on Sunday. Drier air returns for Monday. && .AVIATION /18Z Tuesday THROUGH Sunday/... Initial wind shift is located from near KLNN to KMNN at 17Z should continue to drift southeastward through the afternoon. The strongest thunderstorms will be southeast of this boundary in the better moisture. MVFR/IFR conditions will occur near this convection. We will also need to monitor the true frontal boundary moving southward across Michigan. This boundary doesnt have as much moisture to work with but the instability under the upper level trough will be enough to generate additional showers and thunderstorms into this evening. These will be more scattered in nature and tougher to pinpoint a time moving across any of the terminals. Winds vary across the region with west to northwest winds in the wake of the initial wind shift mentioned above. Ahead of this boundary southwest winds are common. Winds at all locations will shift to the northwest and north as the cold front sweeps across the region this evening into the overnight. Some fog will be possible across the south where the low level moisture will take the longest to be nudged southward. So expect to see some MVFR/IFR fog develop after midnight. OUTLOOK...Non-VFR possible Thursday morning with fog and stratus. && .MARINE... Southwest winds will continue to decline this evening and veer to the north after a cold front moves across the lake northwest to southeast tonight. Those winds will continue to veer to northeast and strengthen to 10 to 15 knots by 12Z Wednesday. This will increase wave heights to 2 to 3 feet in the nearshore zones between Cleveland and Sandusky Bay, creating hazardous swimming conditions for swimmers Wednesday morning into the early afternoon. High pressure will build in from the west to centered over lower Michigan by 00Z Friday. Northeast to east winds will continue through Friday night. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None. MARINE...None. && SYNOPSIS...MM NEAR TERM...MM SHORT TERM...Saunders LONG TERM...Saunders AVIATION...MM MARINE...Saunders
