As the region around Columbus and Cincinnati continues to experience a damp week, the National Weather Service in Wilmington offers a mixed bag forecast. The synopsis from the latest NWS Area Forecast Discussion indicates periods of showers and thunderstorms through midweek, with rain chances lingering through the end of the workweek. However, there appears to be light at the end of the tunnel with drier conditions slated for the weekend into early next week, with temperatures holding steady near seasonal norms before a gradual warm-up.
The near-term forecast for today, according to the NWS, suggests a drier day ahead despite "ISO/SCT activity across the E/SE quarter of the local area at times through early evening." Folks in the southeast third of the ILN's forecast area were previously warned of potential "isolated heavy downpours" that could persist through sunrise. Moreover, areas west of I-75 and north of the Ohio River started the day with a blanket of dense fog, which prompted authorities to issue a Dense Fog Advisory until 10 AM this morning.
Looking towards the short term, which runs from this evening through Wednesday, the NWS anticipates a return of widespread showers and thunderstorms, particularly from daybreak Wednesday onward. This resurgence comes with "better jet dynamics" and an "enhanced LLJ" converging mass and moisture into southern Ohio Valley, potentially resulting in "heavier pockets of SHRA/TSRA" near and south of the Ohio River. So, for those banking on an inch or so of additional rainfall through the short-term period, it seems the area near or south of I-70 may just hit the jackpot.
Moving into the long stretch from Wednesday night through Monday, the pattern does little to allay the prospect of continued showers and the odd thunderstorm through Wednesday night. Despite this, the NWS sees a decrease in shower activity by Thursday, with Friday gazing into clearer skies, albeit stray showers cannot be completely discounted.
Consensus leans towards a return to drier spells and slightly warmer-than-average temperatures. There's a caveat, though, as a rogue cut-off low, should it materialize in the southeastern part of the country, could sway the forecast for southern counties if it edges northward. So while the weather narrative this week might read a tad tumultuous, the outlook is seemingly settling, much to the relief of those pining for sunshine and stable umbrellas.
