Good news for Ohioans looking for a respite from weather extremes—according to the National Weather Service (NWS) in Wilmington, the forecast holds a relatively mild week ahead. A "weak disturbance" is expected to grace the Columbus and Cincinnati areas later today into tonight, but fear not, a steadfast high pressure is slated to settle in for the bulk of next week.
Today, we’re anticipating an influx of high clouds, followed by mid-level ones as a short wave moves southeast from the western Great Lakes, potentially gifting a few showers around the Indiana border late in the day. That said, hold off on unpacking the rain gear because the 00Z guidance keeps the area dry, the National Weather Service remarks, assuring a continuation of palatable, slightly warmer conditions from the previous day. As the night unfolds, the mercury isn’t expected to plummet as steeply as recent evenings, courtesy of the cloud cover holding in some of the day's warmth, leading to above-average lows.
Moving into Sunday, another short wave is set to cruise down from Michigan, bringing a lot of mid-level moisture and some forcing with this, but low levels remain dry. Even so, light rain might just make an appearance west of Interstate 75. The start of the week will see the sun reclaim its territory as the clouds commence their retreat under the influence of an eastward-building mid-level ridge. Prepare for a streak of dry, sun-splashed days as above-normal highs in the mid-80s make themselves at home in the region.
Glancing further into the week, the NWS forecasts an upper high will close off over the Great Lakes, while an upper low develops along the south Atlantic coast, implicitly translating to an extension of dry spells with occasional highs teasing nearly ten degrees above the norm. Lows will remain slightly more generous than standard. However, as Friday inches closer, a potent short wave originating from the Canadian Rockies and taking a tour across the Plains might throw in some rain or storms to close the week, although the latest NBM has chances still rather low. Heights falling, temperatures will be cooler, but not enough to snap the streak of warmth just yet, meaning more warm nights are in store.
For those navigating the skyways, the aviation forecast continues to promise VFR will prevail through the period. High-altitude travelers can anticipate a smooth passage with high and then mid clouds making an appearance—yet these cirrus visitors are unlikely to affect visibility or precipitate any downpour, keeping flying conditions stable and uneventful. A slight wind reorientation happening late this afternoon won’t be enough to rustle up any operational inconvenience, as speeds are forecast to remain below 10 kt.
