Will Twin Falls Finally See a Big Winter Storm This Week?

Twin Falls has had an unusually dry winter so far, with most snow melting away shortly after it touches the ground. But as a new system moves in on Thursday, residents are once again wondering: will it finally stick?

Snow Arrives by Late Morning on Thursday

I spoke to KMVT meteorologist Justin Fanfarilli, who said snowfall is expected mid to late morning hours on Thursday.

"Our latest models had snow coming in around midday, but they’re now trying to push it a little earlier," Fanfarilli said. "We actually could see some snow in the 10 or 11 AM hour. We might get an initial burst of snow, and then it should turn into intermittent snow showers throughout the afternoon."

How Much Snow Can We Expect?

Thursday’s forecast calls for a high near 31 degrees with wind chill values between zero and 10, meaning any snowfall could initially stick, especially on colder surfaces. Winds will come from the east-northeast at 8 to 15 mph, with gusts reaching up to 25 mph.

By Thursday night, temperatures will dip to around 26 degrees, with snow transitioning into a mix of rain and snow before morning. Accumulation is expected to be maybe two inches during the day, with a slight chance of more overnight.

Will It Stick This Time?

One of the biggest questions is whether this round of snow will linger or melt away like the others so far this year. Fanfarilli believes this system could play out differently.

"It actually might be the opposite this time around," he explained. "We’re really cold right now. When the snow starts Thursday morning, we could be in the low to mid-20s. But as the system creates more moisture, it will also warm us up. We should rise into the upper 20s and near 30 by the evening, so it might stick initially, but as it warms, treatment on the roads will work better and the snow will likely stick less."

While this is hardly the biggest winter storm Southern Idaho has seen, it's shaping up to be the most significant one we've seen in the valley so far this winter.

Road Conditions and Safety

With snow likely by midday Thursday and into Friday, drivers should be ready for slick roads, especially in the morning. And it's worth noting that the wind on Thursday could cause drifting snow, making travel in rural areas more challenging.

The cold start on Thursday means roads may become slippery, but as temperatures rise, accumulation could become patchy. Crews will likely be treating roads throughout the day, but there could still be icy patches, especially on bridges and overpasses.

What to Expect for Friday and the Weekend

Friday morning could bring some light snow showers, which may impact the morning commute.

"I'd watch out for Friday morning," Fanfarilli said. "We could still have some areas near freezing, maybe warming up enough to get above freezing, but we’re looking at a high in the low to mid-40s. Snow in the morning could transition into rain showers as temperatures rise."

Is More Snow on the Way for The Weekend?

By Friday night, a mix of rain and snow is possible before clearing up Saturday, with a high of 37 degrees with sunshine. However, another system could bring more snow by Sunday morning, turning into rain as temperatures head up into the low 40s.
