Sunny and dry conditions will continue around Carson City and surrounding counties this week, with temperatures warming up Tuesday through Friday, according to the National Weather Service. A change may arrive by the weekend that could bring colder temperatures, windy conditions and possible snow showers.

Tuesday will bring a gradual warming trend through the end of the week, NWS forecasters said. This will bring temperatures ranging 5 to 10 degrees above average by the end of the week. For Carson City and surrounding valley areas, high temperatures will be in the low 50s through Friday, while the Lake Tahoe Basin will see daytime temperatures in the upper 40s.

For the weekend, a trough is positioned to drop in from a continental polar air mass over Canada that looks to phase with a weak low over the Pacific, NWS forecasters said. Some weather models show the system arriving by way of the Pacific Coast and Central Valley, while others bring the low center in over the Great Basin.

“The discrepancy in track will matter for detail such as precipitation amounts, wind direction and speed, and how much cold air we see,” according to the latest NWS forecast discussion. “If the second scenario pans out, we would see a much colder north to east wind, if the first wins, we would see southwesterly flow, which would moderate the cold air intrusion.”

Forecasters are confident changes are ahead this weekend, but how those changes play out is still up in the air. Check back for updates.
