Cold front triggers heavy rain & snow early Thursday; sun and storms later

The daily forecast from Idaho's largest, most experienced team of meteorologists.

BOISE, Idaho — It was a soggy start to Thursday in the Treasure Valley as a cold front triggered heavy rain across the Boise area in the early morning hours, with spring snow stacking up in the central mountains. By 6am Thursday, the Boise airport had picked up 0.43" of rain, Bogus Basin had 5" of fresh snow, and Tamarack Resort was sporting nearly 9" at the snow stake at 6,600'!

The heaviest precipitation associated with this front will taper off across SW Idaho by sunrise, leading to just splash-and-dash showers through midday, then drier, sunnier but cooler and breezy conditions for the afternoon. Our atmosphere will be unstable and moist enough behind the morning front, though, that afternoon sunshine/heating could trigger some stray thunderstorms, capable of producing bursts of graupel and 40mph wind gusts, so be "weather aware" if you've got outdoor plans this afternoon and evening.

On Friday, the center of a large low-pressure system currently sitting off the coast of Washington will dig south along the west coast and then move eastward over the weekend, triggering precipitation as it moves across the southwest. Southern Idaho will be on the northern fringe of this large-scale system, so some rain and snow showers are possible along the ID/NV border over the Easter weekend, with a slim chance of a shower or two in the Boise area Saturday and Sunday, though overall we should enjoy a mostly dry and pleasant weekend.

Temperatures will be at their coolest today, with a high of 53° and breezy winds in Boise, then will quickly rebound to 60° by Easter Sunday. We kick off the month of April next week with sunny skies and a rapid warm-up, as temperatures skyrocket into the low 70s in the Treasure Valley by Tuesday.
