Another Round of Wintry Weather in the Mountains Tonight.

7dayWest_Sat_Rad_Large_Pac

The week ahead will still be well on the chilly side of average, with occasional storm systems breaking things up between dry spots. Thursday night showers will be cold enough to cause a Winter Weather Advisory for the Lake Tahoe area through the night, but should dry out Friday morning, with high temperatures still struggling to get to the 60 degree mark in the valleys. Saturday will start off dry and cloudy, with the next storm system bringing some mountain rain and snow to the mountains by Saturday afternoon. High temperatures should nudge back up into the 60s. Sunday remains unsettled with showers and highs dropping back into the 50s. Conditions remain cool with isolated to scattered showers through the middle of next week.

Valley Rain and Mountain Snow!

7dayWest_Sat_Rad_Large_Pac

Some big changes are coming our way. The storm track, which for much of May has been well to our north, will drop down for the next week or so, dropping both temperatures and occasional valley rain and mountain snow. For Wednesday, valley temperatures will drop back into the 60s with occasional showers and brisk winds. Snow levels on Wednesday will be quite high, above 8,500′, but those will fall quickly on Thursday, likely to about Lake Tahoe level. Travel over the passes on Thursday could be challenging, and a Winter Storm Warning has been posted on the west side of the Sierra. The valley will see Thursday highs drop to the 50s with rain likely, especially on the west side, as there will be some shadowing. Temperatures rebound a bit into the weekend, but occasional showers are in the extended forecast.

Guard The Tomatoes!

Looking at this forecast, a vision of the little girl in the movie “The Shining” keeps popping up in my hear….”It’s baaaaaack….”

Just when you might have thought that warmer spring-like weather was here to stay, a fast moving inside slider type of storm system will make a quick but dramatic pass through the region Tuesday. High temperatures will fall more than 20 degrees from Monday’s highs as a low drops down from the north. This kind of pattern will likely result in as much or more precipitation in the valleys compared to the mountains, so it shouldn’t pose any real difficult travel issues over the passes. Snow levels will range from 6,000-7,000′.

Rainfall
By Wednesday morning the skies will clear and we can expect a moderate to hard freeze in the valleys, so take measures to protect any frost sensitive plants. Temperatures will climb quickly back into the 60s Wednesdays and the 70s by Thursday. A slight chance of showers returns to the region by the weekend.

Still in a Stormy Pattern

7_Day_fullWest_Sat_Rad_Large_Pac

This will be an unsettled weather week, with occasional valley rain and mountain snow and rain. Snow levels will stay well above the valley floor through Thursday, and would even pop above Lake Tahoe a bit here and there, before dropping back to the valley floor by Friday. The mountains do have a Winter Weather Advisory posted starting 10 pm Tuesday which will run through noon on Thursday. It’s a fairly warm storm, so the snow will be wet and heavy.
In the valley, there will be fairly significant shadowing occurring, but some locations could still see several tenths of an inch of rainfall over the next few days. High temperatures stay in the low 50s through Thursday before dropping to the low 40s on Friday, at which time some snow could reach the valley floor, although I don’t expect heavy accumulations all the way down here. Through the course of the week the mountains could pile up anywhere from a few inches at the Lake to two or more feet along the crest of the Sierra.

High Winds in Valley…Mountain Winter Storm Warning

5dayWest_Sat_Rad_Large_Pac

In a nutshell, a very stormy week. High valley winds will continue for the next couple of days, although probably not quite as powerful as the winds we saw Monday afternoon. A series of storm fronts will slam into the mountains, with snow levels likely to stay above the valley floors for the most part, but should reach down to Lake Tahoe through most of the week. Travel over the passes will be extremely difficult through Wednesday (A Winter Storm Warning is posted for the mountains until early Thursday morning.) In the valley, a High Wind Warning is in effect through this evening. The strong winds will create significant rain shadowing, so rainfall amounts will be mostly limited to the western foothills, although some spillover rainfall should be expected through Wednesday. Temperatures will range from the low 50s to the mid-40s through the rest of the week.

Still Unsettled…Just Not As Strong

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.
