Still Unsettled…Just Not As Strong

7day

While the weather pattern remains generally unsettled for the next week, the storms moving through the region shouldn’t be as strong as what we’ve had the first six weeks of the year. Scattered snow showers through Thursday, with a possibility of some lake effect snow south of Pyramid Thursday afternoon, could put down anything from a dusting to a few inches of snow in various valley locations. By Friday and Saturday, we get a bit of a break with temperatures warming in the 30s Friday warming into the 40s for the weekend. Another weak to moderate storm moves in Sunday and Monday bringing with it a chance of additional rain or snow in the valleys.

Brief Break…Cold Night…Snow Returning Wednesday

7daysatrad

We have a brief break in the action before the next storm system comes through, and while we may see some more snow coming our way Wednesday into Thursday, it’s not expected to be on the same scale of some of the previous storms to come our way these last several weeks. Because the next storm will be dropping down out of the north, it will exhibit “inside slider” tendencies, which means it’s not likely to be a huge mountain snow producer, but a few valley inches are possible. In addition, the cold flow could create additional Lake Effect snowfalls off the southern ends of Lake Tahoe and Pyramid Lake.

Snow on the ground will allow temperatures to drop into the low teens and single digits tonight, and the super moon should light up the valley pretty well overnight.  High temperatures will stay in the 30s through the rest of the work week, before warming into the 40s over the weekend.

Rain Turning to Snow

7daysatrad

The heavy valley rains from earlier will turn to snow over the next few days…enough to cause a Winter Weather Advisory to be posted for the Reno area until noon Friday. Total valley accumulations will vary greatly depending on the elevation, but could range from a couple of inches near the airport to as much as a foot in the upper foothills. In the mountains, a Winter Storm Warning will extend through the weekend into Sunday afternoon, with high winds and heavy snows once again making mountain travel anything from difficult to impossible. By the end of the weekend, Lake Tahoe could see another couple of feet of snow, with 5-6′ possible in the upper elevations near the crests.

Temperatures will drop dramatically, likely not exceeding 40 degrees through the middle of next week.

More Storminess to Come

7daysatrad

There’s a lot of stormy weather left this week, with a wet and warm storm gradually transitioning into a somewhat less wet and somewhat colder storm. Significant rain below the 8,000′ snow level overnight tonight into tomorrow morning has caused an Areal Flood Advisory to be posted for the Lake Tahoe area, as some leftover snow is still clogging up storm drains. As we go through the day on Thursday, snow levels will gradually lower to about 6,500′, and then drop all the way to the valley floor by Friday, although the deepest moisture will be past us by then.
High winds will continue to plague the valleys, and the High Wind Warning continues for western Nevada through Thursday. High wind gusts of 60 mph are possible, with even stronger blasts in the wind-prone areas.

As the valley rain switches over to snow late Thursday night into Friday, precipitation amounts will lessen, but a few additional inches of snow over the course of the weekend is not out of the realm of possibility.

Weather Getting Wild Again!

7daysatrad

Wild weather is returning to the region, with high winds, significant valley rain and heavy upper elevation snow…all this before the weekend arrives. A strong cold front with a powerful jet stream will move into the region starting Wednesday. Snow levels will be fairly high, possibly rising to 7,000′ or more Wednesday, and heavy high mountain snow will also mean heavy rain in the Lake Tahoe and Reno-Sparks areas. While there might be some localized street flooding thanks to snow blocking storm drains, it’s not likely the larger river will reach flooding stages, even though there will be some rises. A Winter Storm Warning is in effect from late tonight through Thursday, with snow accumulations ranging from nothing in the valleys to several feet above 7,000′ by Thursday night.

Rainfall
A High Wind Warning for the valleys will now start early Wednesday morning and run through Thursday, accompanied by occasional heavy rain. Temperatures will climb to the low 50s Wednesday (with rain likely) and will gradually fall to the low 40s and upper 30s by the end of the weekend. There’s also a slight chance of some freezing rain early Wednesday if warm rain falls into trapped cold air prior to the winds breaking up the inversion.

Stormy Weekend, Tough Mountain Travel

7daysatrad

Winter weather will come charging back into the region this weekend, and the National Weather Service has issued a mountain Winter Storm Warning from Friday afternoon all the way through Monday. There are two separate systems coming through, the first of which will bring snow above 6,500-7,000′ on Friday afternoon through Saturday. Another storm front will come in later Sunday, this one colder, which will drop snow levels all the way down to the valley floors. The mountains will provide enough lift to keep precipitation up there going almost continually between the two storms, and although things may ease up a bit Saturday night into Sunday morning, it is best you get any mountain travel out of the way before late Friday afternoon. By the time the second storm ends we could be looking at another 4-5 feet of snow in the upper elevations of the mountains.

In the valleys, initially there will be a fair amount of shadowing late Friday, but enough spillover early Saturday to make some rain almost a sure bet. The second storm Sunday night into Monday could create some commuting issues with slippery roads Monday morning.

Winter Storms Returning

7daysatrad

We have another couple of mostly dry and mild days left before a series of winter storms come back through the region. High temperatures on Thursday will top out in the upper 50s and then again in the mid-50s on Friday. Winds will also pick up on Friday ahead of a moderately strong winter storm (A Winter Storm Watch has been posted for the mountains from late Friday through Saturday). There will be significant shadowing occurring in the valleys with this storm, but some spillover valley rain is expected starting late Friday night into Saturday. The mountains can expect to see anywhere from several inches at the lake to a couple of feet of snow in the upper elevations over the weekend. Snow levels could drop to the valley floor by the end of the weekend, although heavy accumulations in the valleys aren’t expected.

A Return To A Stormy Pattern Ahead

7daysatrad

After a mild and dry stretch to nearly finish off January, it looks like some wetter weather will work its way back into the region. Tuesday should stay mostly dry and mild, with only a few showers possible up in the mountains. Precipitation chances increase slightly Wednesday and Thursday with a couple of weak systems moving through, with stronger storms moving through Friday and Saturday. Snow levels should remain above Lake Tahoe until the weekend, when they will drop to somewhere between the lake and the valley floor.

Blizzard Warning Upcoming for the Mountains

7daysatrad

A series of powerful storms will make travel across the mountains difficult if not impossible late Wednesday through Thursday. In the short term, the valley is under a Winter Weather Advisory tonight into early tomorrow morning, with accumulations of up to a few inches in the valley with more possible in the foothills. Wednesday starts with a bit of a break, before a very powerful storm brings high winds and heavy snow to the mountains (and possibly significant rain to the valleys.) A Blizzard Warning is in effect above 7,000′ for the mountains from 7 pm Wednesday until 7 am Thursday. A Winter Storm Warning is also posted starting 4 pm Wednesday running into early Friday morning. Conditions dry up Friday and Saturday before the next storm (not as strong this time) comes in on Sunday.

Treacherous Mountain Storm Approaching

7daysatrad

A very active week is setting up weather-wise in our region. A series of storm fronts will move through the region before drying up at the end of the work week. The first storm will likely result in fairly light precipitation of rain and snow into Tuesday morning, with the focus of heavier precipitation off to the east. After a brief break, a couple of stronger storms will move through the region Wednesday and Thursday, with very strong impacts on travel, especially in the mountains. Snow levels will vacillate between the valleys floors to just above Lake Tahoe as the storms move in. The strongest storms will likely come late Wednesday night and Thursday afternoon. High winds could create blizzard conditions over the mountains on Thursday.
Conditions dry out by Friday, and the weekend is shaping up to be dry and mild.
