I certainly thought that today, at the very least, would be the last day for showers and storms in the mid-Atlantic. If I am being fully honest, I will admit that I kind of thought yesterday would be that day. Instead, there is just the barest threat for showers and storms even tomorrow.
EDIT: I guess I will note that the precipitation threat is gone tomorrow between Cumberland and Louisville. I was close, just used the wrong forecast.
I know the forecast is long expired now, but the road trip forecast I published last night looks good. The light bands of showers through the Mountaineer State are continuing at this hour, but there is no thunder activity, and it isn’t very heavy. Post frontal, but still northerly flow from a strong area of low pressure.
The thing about summer is that patterns get slow and sluggish, less dynamic. A cold front has sagged into the middle of the Ohio Valley and is connected with a stationary front through Montana. Not strong, not moving much, but present, which will mean isolated storms within a couple hundred miles o the boundary. Not strong, but not moving, either.

All right, let’s take a trip! It’s only going to be a 7 hour trip through the mountains of eastern Kentucky and West Virginia between our two end points on this Sunday journey. I can definitely say that these 472 miles would have been a lot more interesting today or yesterday, but alas, we try to avoid thunderstorms when driving.
Low pressure has really figured itself out in the Gulf Stream, and the cold front associated with it left a healthy stripe of wind damage reports from the Delmarva to the Smokey Mountains. Already today, the heaviest weather has remained south of our route, and northerly flow will remain in place on Sunday over the area surrounding West Virginia. The feature is strong enough, and the atmosphere is rich enough that there might be a few stray showers riding those north winds as we head towards western Maryland, but the most pleasant weather the region has seen in a while with only passing clouds will define the majority of the day.
Hello, and good evening, I hope you weren’t up waiting fore this late night forecast. It’s here anyway.
At 1253AM, ET, Cumberland was reporting a temperature of 78 degrees with clear skies. Cumberland was lucky to evade a round of very heavy thunderstorms earlier today, which brought strong winds to West Virginia and northern Virginia, as well as parts of eastern Maryland, but left western Maryland unencumbered. All these storms have been running along a slow moving cold front that is expected to start to resemble a continuous bowing cold front, running from the Chesapeake to the Mid-Mississippi Valley. The thunderstorms along the boundary will start to organize it’s southward march by tomorrow afternoon. There is a mass of thunderstorms presently moving eastward in the southern Great Lakes that will be ongoing through the morning, and may delay the southerly turn a bit. The change in direction and redevelopment of activity will likely limit the potential severity of thunderstorms on Saturday for Cumberland, though a gust of wind or hail could be seen in the mid afternoon. Cold – relative to what has been seen – air will press in to make Sunday a satisfying conclusion to the weekend. Tomorrow – Scattered showers and thunderstorms, a threat for severe storms, High 90, Low 69 Sunday – Mostly sunny, High 86, Low 65
TWC: Tomorrow – Thunderstorms likely in the morning. Then a chance of scattered thunderstorms in the afternoon. Gusty winds and small hail are possible High 89, Low 71 Sunday – Sunshine and clouds mixed. A stray shower or thunderstorm is possible. High 86, Low 67
AW: Tomorrow – Mostly cloudy and humid with a shower and thunderstorm; thunderstorms can bring flash flooding and localized damaging wind gusts High 90, Low 70 Sunday – Less humid with intervals of clouds and sun High 87, Low 69
NWS: Tomorrow – Scattered showers and thunderstorms before 8am, then scattered showers between 8am and 11am, then scattered showers and thunderstorms after 11am. Partly sunny, High 91, Low 71 Sunday – Isolated showers and thunderstorms. Mostly sunny, High 85, Low 67
WB: Tomorrow – Partly sunny with scattered showers. Isolated thunderstorms in the morning then scattered thunderstorms in the afternoon. High 86, Low 72 Sunday – Partly sunny in the morning then clearing, High 82, Low 70
WN: Tomorrow – Partly cloudy with scattered storms, High 91, Low 72 Sunday – Partly cloudy with isolated storms, High 85, Low 67
CLI: Tomorrow – Light rain showers, High 91, Low 70 Sunday – Sunny, High 86, Low 70
Some overnight imagery. Thunderstorms in Pennsylvania have tapered off, so not much to impress at this late hour.
Expect August to be dominated by two different stories. The continuing heat, which has lead to extreme warmth in the north Atlantic, and the approach of peak hurricane season. All other things being equal, you might expect that the increased sea surface temperature would lead to an increased risk for hurricane development. There is a long way to go and it certainly remains to be seen, but at this point, it’s still pretty quiet out there.
Of course, while it feels like a slow season, the next named storm will already be the 5th of the year.
Severe weather has been pretty sparse in Minnesota lately, but we have a severe thunderstorm watch just issued, and it is on the very northern end of the thunderstorm risk today. There is a little bit of activity in eastern Minnesota so far, but it seems like a strange sight! We’ll see how it goes.
I think, if anything, the “updates” have made me feel better, keeping in touch wit the weather world and sharing my thoughts on the site, instead of the meandering carcass of Twitter makes this site seem more current and me more engaged. That said, this has been a heck of a month, and the forecast we are verifying today, in Harrisonburg, Virginia, somehow occurred 2 weeks ago. At that time, a feature was attempting to ascend and descend the Appalachians into Harrisonburg, and I can now report, it was successful. Over the course of that weekend, nearly 3/4ths of an inch of rain fell, about as expected. Heavier thunderstorms on Saturday, light rain on Sunday morning, followed by a fairly manageable end to the weekend. Clime missed the thunder on Saturday, somehow, but everyone else hit on that front, and The Weather Channel continued a strong month, and earned the W. Actuals: Saturday July 15th, .67 inches of rain in a thunderstorm, High 89, Low 63 Sunday – .05 inches of rain, High 85, Low 68
