Monitoring Prospects For Heavy Weekend Rain…
A combination of ingredients are coming together to offer up the potential of heavy rain for portions of the region this weekend.
An approaching cold front will drop slowly southeast out of the Plains while a tropical low moves inland from the central Gulf Coast.
The precise placement of the front will serve as the focal point for heavy weekend rains. As we’d expect from this distance, modeling disagrees on the all-important specifics. Using a model blend, central Indiana is on the table for heavy late week-weekend rain as of now. Precipitable water values (PWATs) will be above 2″ and suggest the threat of torrential downpours, including localized flash flooding across the Ohio Valley. Eventually, the cold front will sweep the tropical-rich moisture away from the region and cooler, much less humid air will press in by this time next week.
We still have time to watch the evolution of things play out as we progress through mid week. Stay tuned as we “sure-up” the details and hone in on the area where heavy rain is likely.

Dry And Turning Hot; Watching Late Week…
Highlights:
- Sun-filled days
- Heat cranks up
- Late week questions
Turning Up The Heat…After a refreshing weekend, the heat returns later this week. Look for highs in the lower 90s with an oppressive feel to the air, as humidity builds. “Air you can wear” will be an appropriate forecast title come mid week. The forecast is easy through the midweek stretch with sunshine as the rule.
Things become more unclear as we approach the back half of the week and the weekend. We note the GFS is rather progressive in swinging a cold front through here with scattered showers and thunderstorms, followed by a significantly cooler/ drier air mass a week from today. On the other hand, the European solution is drastically different as it slows the front to a “crawl” coming through the Ohio Valley and also entrains GOM (Gulf of Mexico) moisture from the serious rain/ flood maker later this week across the Gulf states. It’s a significantly wetter look, locally, and a situation we’ll continue to keep a close eye on in the coming day, or two.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 0.50″-1.00″

SST CA Model Weighs In On The Upcoming Winter…
It may only be August, but thoughts here are solely focused now on the upcoming fall and winter seasons. We received an update today from the sea surface temperature constructed analogue model and the look is a “mighty fine one” if you enjoy wintry conditions, locally.
As we’ve mentioned in previous video and text posts, the once-thought moderate to strong La Nina doesn’t appear to be taking shape and instead we’re likely left with a weak La Nina to neutral look. Factor in the positive PDO and the overall pattern is one that could yield cold, snowy times, locally, especially the middle and latter parts of the winter season. (No reason to get too specific this far out).
In any event, today’s update is an “intriguing” one for winter enthusiasts across the region.
