My friend lives in Golden, Co, looks like they picked up a few inches of snow.

Hoping for 1-3" tonight/tomorrow AM. The lack of snow here since early February has been truly exceptional.

 

Most reports around Westminster show 4-5" it looks like.

There were a few lake effect snow showers this morning for parts of the SLC area, but nothing at my place. 

06z GFS showed over 2" of liquid this weekend, but most models are closer to an inch. Storm looks similar to many over the winter with a strong low crashing into central california and moving eastwards towards my area. These tend to have good moisture taps with them.

Should see showers and thunderstorms pick up tonight and tomorrow here. Rain will switch to snow for a slushy inch or two on Sunday. After that we quickly rebound to warm weather again.

Still lots of questions for the Saturday night/Sunday system for here. Euro has been most consistent showing about 2-4" of snowfall for several days now while the GFS/GEM/NAM have been all over the place. 12z GEM was the most bullish this morning showing about 8-10" of snowfall in the same period. 

 

2-4" seems like a safe forecast at this point but still a couple more runs to fine tune things. Either way, it's nice to see the pattern turning much more active after a very benign March.

Looks like the NWS is onboard. They just issued a Winter Storm Watch for my area and as of right now think 6-12" for elevations at or above 5,000' (I'm at 5,350').

 

Seems pretty bullish to me but maybe the GEM is onto something...

Climo wins. The ULL always forms 100 miles south or east of having significant effects on Missoula, it can only effect locations on continental divide or east. It was nice seeing NAM/GFS/GEM agree for  half a foot here in town for about 24 hours though, and 3' in the Rattlesnake/Mission mountains.

The shortwave will not hit you, and this map also implies that the ULL will not be able to pull the moisture back into your valley, so you will end up with like an inch or two. If you look at the radar trends, it looks like the old solutions(favoring GNP, Missoula, Great falls and not Bozeman or Billings) were right because the returns are moving north of the blue mountains into the Columbia basin and the Palouse.

Wasn't aware that this was a competition. That map still shows about 3-5" for me and the WRF has performed horribly this year. The Euro has shown the most consistency with the ULL which still gives my area 3-6" which seems like a good forecast at this point. This was never looking like a major event for this area but rather a moderate spring storm.

It's not, but I don't think we ever get a lot of snow out of the same snowstorm(think Seattle & Portland). I was just excited about getting a lot of snow for going last day of resort skiing tomorrow. Probably will end up getting sorting in town too (trace-6"). The boundary is very sharp with this one, at least for valleys, I don't think a lot of people will see 3-6" east of the divid it will be either an inch or a foot.

There is a stark difference between Bozeman and Missoula as the two cities sit in two completely different climates and are ~1,600' in elevation apart. Bozeman sits in a cold/dry continental climate whereas Missoula has a cold semi-arid climate. Bozeman is quite unique in that it receives plentiful moisture year-around for a continental climate and averages 86" snowfall to Missoula's 45" annually.

 

And an inch to a foot?? That's quite the range! :P

Yes I know that my climate doesn't deliver as much snow as most cities in Montana. Only plains & cities further south in Bitterroot valley get less. My point was that you would need the low to take a very unusual track to give a significant snowstorm to both Bozeman & Missoula. And yeah, look at those gradients on the silly map.

Starting to get worried this storm will go north of everyone and hit US/CA border and MT-hiline. It's certainly not encouraging to see that band go north of Spokane and not pivot.

NWS is forecasting 1/2 -1" for Missoula. Were you expecting them to bust badly?

Current low placement is pretty much exactly as progged. Currently crossing through eastern ID moving NE. I think the biggest concern this evening is a lack in cold source. It appears that the low isn't pulling as much cold air south that was earlier modeled. If this trend continues we may begin to lose out on the moisture before the cold air arrives.

 

With that all said, the 18z GFS/NAM and the 22z HRRR looked pretty promising for tonight through tomorrow morning.

Accumulating snow levels were a touch above 4000' with the last shower. Got down to 37 here, probably had flakes in the air well below 3.5k'

Yeah I see Butte just switched over which spells good news for me here once the precip arrives in the next hour or so.

 

Looks like your best bet at at some accumulations is with the wrap around moisture later tonight.

Flow is becoming more northerly, shower coverage is increasing again. Shouldn't take that much more to bring the snow level to the valley floor here.

Heavy, heavy wet sticking snow has begun here. Heaviest snow I've seen since we moved here in mid January.

 

Temp went from 40º down to 32º within about 2 minutes. Gotta love living in the Northern Rockies!

I had .97" of rain before it switched to snow and clogged my gauge up. About 2" of accumulation so far.

 

A healthy lake effect band is kicking up so may see a few more inches by morning.

Hasn't stopped snowing since it began last night around 9pm. Looks like about 4-6" so far and still coming down moderately. Hard to believe it's April 9th and we're about to XC ski from our house and up into the hills. Currently 27º.

The Bozeman Airport is actually in a different town (Belgrade) and sits in the center part of the valley at about 4-500ft lower than most of the actual city of Bozeman. It's definitely not a very accurate representative of what's actually happening in the city.

Great falls did okay, complete and total bust for everybody else(including snowbowl, only 6" :(. Missoula got about .05" of qpf in snow form we'll see if there was an accumulation at the airport, there isn't one here right now on southeast end of town.

Most years there is at least a little bit of something, so not really unusual. Looking ahead this was probably the last snow storm of the season though. 

 

There was another 2" or so overnight.
