Good Sunday evening everyone,
I hope all of you enjoyed the weekend. A shortwave trough was moving through California and Nevada today, which brought extensive cloud cover over Nevada as well as the breezy conditions to Tahoe. Conditions will remain similar to today for the first half of the week, as we will see in the forecast.
Switching to the forecast and focusing on the first half of the week, on Monday the shortwave trough will continue to move out of the region, as a shortwave ridge builds off the coast. The ridge will propagate over the west coast on Tuesday. Even though a ridge will be present over California, skies will likely be cloudy, as a fair amount of upper and mid level moisture is anticipated to move over California (no precipitation is expected, however). The ridge will likely move out of California and Nevada by Wednesday, as a shortwave trough moves into northern California. The shortwave trough will likely drop temperatures in the Tahoe and Reno areas (temperatures may be in the upper 40’s and upper 50’s for Tahoe and Reno, respectively), and may also bring precipitation to the Reno and Tahoe areas.
Focusing on the second half of the week, northwesterly flow may develop over California on Thursday as the shortwave trough broadens. Temperatures for Tahoe and Reno may remain suppressed and slightly colder than Wednesday. The northwesterly flow may increase in strength on Friday, as the trough east of California and Nevada amplifies. Temperatures may begin to increase for Sacramento, Reno, and Tahoe. The northwesterly flow over California may weaken on Saturday. Temperatures may continue to increase across the region.
That about wraps up this week’s update. In summary, conditions will likely remain similar to what was observed today through Tuesday (with slightly weaker surface winds for Tahoe). Temperatures may drop for Reno and Tahoe on Wednesday as a shortwave trough moves into northern California (Sacramento may not see a drastic change in temperature). Along with the decrease in temperatures, the trough may also bring precipitation to the Tahoe and Reno areas. Temperatures for Tahoe and Reno may remain suppressed on Thursday, with highs reaching into the mid 40’s and mid 50’s, respectively. Temperatures may slowly increase across the region on Friday and Saturday. As always, enjoy the weather!

It has been a rather cloudy day for California, and an especially cloudy day for Nevada. The cloud cover and wet weather has been caused by a shortwave trough moving through California. The trough brought precipitation to the two states yesterday, and continues to bring showers to parts of California and Nevada today. The trough will continue to linger over the west coast for a couple more days, as we will see in the forecast.
Switching to the forecast and focusing on the first half of the week,on Monday the trough will continue to move through our region. Showers will likely persist over eastern Nevada, but not over the Reno, Tahoe, and Sacramento areas. On Tuesday, the trough will continue to linger over California, as it begins to transition into a closed low. The closed low will likely begin to move out of California by Wednesday.
Focusing on the second half of the week, zonal flow will likely develop over California on Thursday. Temperatures will likely begin to increase by Thursday. On Friday, a ridge may begin to build off the west coast. The ridge may weaken on Saturday as it propagates eastward.
That about wraps up this week’s update. In summary, a trough will slowly move through California and Nevada through the first half of the week. No showers are currently expected over Tahoe, Reno, or Sacramento as the trough moves out of the region. Temperatures will likely remain suppressed until Wednesday or Thursday, at which point temperatures will slowly begin to increase. By the end of the week, temperatures may be in the lower 60’s for Tahoe, the lower 70’s for Reno, and the mid-lower 80’s for Sacramento. As always, enjoy the weather!
Multiple fires are burning on the west side of the Sierra with the Valley, Butte, and Rough Fires being the largest, and producing the majority of the smoke we are currently seeing in the Sierra and western NV
The Butte fire is located South of Highway 88, East of Highway 49, North of Highway 4
Southwest to west winds will be increasing the next several days, which will transport additional smoke from these fires into the region, likely worsening conditions. Check airnow.gov for the latest air quality information.

National Weather Service Reno Nevada 307 am PDT Thursday Sep 19 2013 Synopsis... Light southeast winds and warmer conditions expected today and another night of below freezing morning lows is possible in the Sierra valleys tonight. A strong low pressure system will move into the Pacific northwest Friday and Saturday, bringing gusty winds, below normal temperatures, and a few showers to the area. Short term... clear skies will prevail across much of the western U.S. As short wave ridging briefly passes through the region. Expecting warmer temperatures this afternoon as winds shift out of the southeast with highs today right around season averages. Lower 80s are forecast across much of western Nevada with middle 70s for Sierra valleys. Thereafter, we will see a Stark regime change as an unseasonably potent low pressure system develops off the West Coast. The main weather impacts this low will provide are strong winds beginning Friday afternoon and temperatures 15 to 20 degrees colder by Saturday. The core of an unseasonably deep upper low (3-4 Standard deviations) will remain offshore of the Pacific northwest on Friday morning, but [Read more]
