KEY MESSAGES
* Scattered snow showers will continue through early morning in the Sierra, continuing travel impacts and delays. Isolated thunderstorms could bring brief high snowfall rates and embedded lightning.
* A chilly start to Thursday will lead to a drying and warming trend Thursday and Friday. Chances for afternoon showers return this weekend, mainly over the mountains.
DISCUSSION
The final waves of snow will make their way across the Sierra this morning, with a more scattered showery pattern emerging by late morning. The nature of these showers will be more convective, and they could bring a brief heavy burst of snow as they pass. Until the showers clear out of the region later today, check with CalTrans and NDOT for the latest road conditions before heading out the door.
Otherwise, chilly northerly breezes will carry a colder airmass, which will be noticeable this morning and Thursday morning. As of Thursday a warming trend ensues, and will keep us on the warmer side of spring temperatures into Friday.
Despite this reprieve in the cold, damp weather pattern of recent, this warmup will be subtle and gradual. In fact, a trough pattern situated along the West Coast will keep temperatures near average as yet another system swings into view for the weekend. With temperatures wanting to fluctuate, instability may build in this weekend, allowing showers and storms along the Sierra to develop to heights that would support the growth of small hail and graupel along with occasional lightning strikes.
