For Ohioans looking forward to a respite from the summer heat, the National Weather Service in Wilmington has good news: high pressure will linger over the region, ushering in cooler-than-normal temperatures and dry conditions into the mid-week. According to a forecast discussion published by the NWS, today's high in the Ohio Valley will range from 75 to 80 degrees, which is "5 to 8 degrees below normal."
A mixture of mid- and high-level clouds will appear early this morning, which is attributed to weak isentropic lift, particularly impacting the southern areas. Clear skies are expected to follow, save for some afternoon cumulus cloud development. Associate these clouds with daytime heating, and they will disappear by evening, leaving behind high-level cloud scatter, with overnight lows anticipated to bottom out in the "lower and middle 50s," as per the same forecast discussion from NWS.
Surface high pressure will continue to dictate the weather narrative through Monday, according to the NWS, with an "increase in mid and high clouds ahead of a shortwave and pcpn to our west." The high temperatures will float in the upper 70s to lower 80s. In aviation terms, this means predominantly VFR (Visual Flight Rules) conditions for pilots, with the morning's clouds giving way to clear skies by the afternoon.
The long-term outlook suggests a persistent dry spell dominated by surface high pressure, with only an "isolated shower" possible early into the week as a weak shortwave passes through. Tuesday temperatures are forecast to hit the upper 70s in the north and low 80s in the south, indicating a slow uptick. According to this NWS weather briefing, our next significant chance of rain isn't on the radar until late in the week when "as a
loosely organized wave moves in from the west." Unfortunately, for those hoping for a deluge, this system doesn't promise to be a big hitter in terms of rainfall, with the NWS noting the expected QPF (Quantitative Precipitation Forecast) won't make much of a dent in any drought conditions.
In summary, most of Ohio can expect a serene blanket of high pressure to foster a calm weather pattern in the coming days. So, while umbrellas may collect dust a while longer, it appears the sunscreen can stay within arm's reach for now.
