Yesterday’s storms certainly delivered on the wind damage potential — we had dozens of tree and structure damage reports from the Triangle northward:
Those storms are long gone now, and things are looking good for the rest of the day! We’ll see plenty of sunshine, but strong northwesterly winds will keep temperatures a few degrees below-average:More importantly, the humidity will be noticeably lower! Dew points around 60° may not qualify as “refreshing,” but at least the mugginess will be tolerable:
Temperatures tonight will drop off nicely, ending up in the 60s by early Saturday morning:
The weekend forecast is…complex. The upper-level winds that steer the weather across the country are going to be arranged in a way that could send clusters of storms toward central North Carolina. The HRRR model’s radar simulation from 9:00pm today through noon Saturday shows that the storms will develop over a thousand miles away (!) and track into central North Carolina early Saturday as they diminish in intensity:Our in-house RPM model shows the morning showers……then a break for much of Saturday, when we’ll warm up to the mid 80s……then some more scattered showers and storms by late afternoon and early evening:Some of the afternoon/evening storms could be on the strong side — the Storm Prediction Center has included our western counties in a “Marginal Risk” (level 1 of 5) of severe weather:I think that will be expanded to include more of central North Carolina. The SPC’s own forecast model shows a 40-50% chance of at least borderline severe ingredients coming together Saturday evening:
Okay, so here’s where I hedge my bets. Trying to forecast this type of weather pattern is very tricky…in fact, it brings the word “quixotic” to mind.
Here’s why: those storms are coming in from a LONG way off. A little change in their path means they could miss central North Carolina entirely tomorrow morning. If the first batch of showers misses us, it re-arranges the whole setup for the rest of the day…temperatures would be warmer, the late-day storms could behave differently or even fail to develop. A third cluster of storms heads our way Saturday night, and its behavior will be determined by what the first two clusters do. Chaos theory takes over in a hurry, is what I’m saying.
So take the weekend forecast with a grain of salt roughly the size of Kansas. Be flexible with your outdoor plans, but I wouldn’t necessarily cancel anything unless you absolutely positively need a guarantee of dry weather. It doesn’t happen often, but I’m more confident in the long-range forecast than I am in the 48-hour forecast — next week just looks hazy, hot and humid:
- Summer starts at 11:54am today — you can thank a 4-billion-year-old rock for the changing seasons.
- Earth is not the only planet with solstices and equinoxes; any planet with a tilted rotational axis would see them, too.
- Our sun affects the planets, of course. Now, we’re learning more about how the planets influence the sun.
- Above the Arctic Circle, temperatures can drop as low as –67°C and darkness can last nearly the entire day. A new study reveals how reindeer have evolved to cope with these tough conditions.
- As disaster costs climb, governments face an agonizing choice: Which communities to save first.
- Global warming is expanding the territory of some terrifying microbes.
- Meteoric smoke could be key to putting clouds on Mars.
- NASA this week confirmed that its Jet Propulsion Laboratory has been hacked.
- A new DNA microscope acts like Google Maps at the cellular level.
- An experiment with “lost” wallets reveals that people are surprisingly honest.
- Which regions/countries trust scientists the most? A new global survey rounds up the numbers.
