Rainfall Expected for Nevada; Winter Weather Advisory Issued for the Eastern and Central United States on Friday

Bryan Dijkhuizen

The Active weather is expected to resume today, bringing with it lots of precipitation that will last through the next Christmas weekend and into the middle of the following week.

As clouds build throughout the region this morning, temperatures will remain somewhat higher than yesterday. This will continue into Wednesday night.

This morning, a surface of, or weak frontal boundary, connected with a rising 500Mb shortwave spans through northern Nevada before sinking somewhat southward and turning virtually east-west oriented about north of the US Highway 50 corridor this afternoon.

The outcome is a light dusting of snow across northern Nevada this morning, followed by rain or a rain/snow mix for places below 5500 feet in the afternoon as surface temperatures rise into the mid-30s to mid-40s this afternoon.

We don't anticipate any significant snow or rain accumulations or, for that matter, any traffic concerns. Furthermore, there is no precipitation for regions south of US Highway 50.

In the highlands of northern Nevada, a few inches of snow is likely, with the most significant totals expected in the Santa Rosa Mountains and the mountain peaks around the Black Rock Desert, respectively.

Meanwhile, a new frontal wave is emerging and is expected to move northward into southern California by Wednesday afternoon.

In addition, a new emerging wave emerges in far northern California or southern Oregon, which is related to a resounding 500MB low-pressure system burrowing south off the coast of British Columbia.

Even though these two systems are still independent of one another, they are both expected to spread cloud cover over the area by Wednesday night as they approach the region.

By Thursday morning, the frontal wave over far southern Nevada had gone into Arizona, with minimal influence on east-central Nevada and the surrounding areas.

Meanwhile, the frontal wave from the north has dug its way into the far northwest Nevada/Northern California region.

By Friday afternoon, the snowfall intensity should begin to decline as the front and trough depart the state, and more zonal flow takes its place, according to the model consensus.

Once again, an enhanced winter weather advisory will be in force for the eastern and central United States through Friday morning.
