Exceptional Storm

Summary

Snow showers will continue on Wednesday before finally clearing out by Thursday morning. We'll see a break in the active weather through Sunday. Temps will stay quite cool, but the sun will come out for a great 5 day period of sunny weather to get some turns in. Next week we could see a weak system in the middle of the week.

Short Term Forecast

I apologize for the later post today. Was really hopeful to get something out earlier but it's been quite a hectic time for me lately. I have family that lives in the mtns. of Northern California and is coping with this relentless winter and I've had to help them shuffle a lot of things around as their roof has been leaking from the incredible snow load. On top of that I've had quite a few job changes in the past few months. I'm sure that all that will settle down just in time for winter to end... or not as this winter just wants to keep going no matter what! 

Storm Totals

Wow... what a 24 hour period. I knew it would be a good storm and I forecasted amounts that I thought were conservative and I very much think my forecasts will be beaten. The cold air came in sooner, the moisture has stuck around for a good long while and the intensity of the precip has been unprecedented. There was even a reported Tornado in the LA Basin this afternoon touching down in the Montebello region. 

With regards to how much snow fell... quite a bit. 22 - 26 inches at Mtn. High. Another 16 - 20 inches by the 8PM measurement at Mt. Baldy with likely another 8+ inches overnight. 24 - 30 inches of snow fell at Big Bear Mtn. Resort and 30 - 32 inches at Snow Valley. Every mtn. has exceeded 2 FT of snow for this storm with Bear Mtn. and Snow Valley reporting at least 3 FT now. 

Wednesday Snow Showers

There have been snow showers throughout the day and those could continue into early this evening. The storm is definitely winding down and should be completely out of our region by late tomorrow morning. Resorts are struggling today to keep up with the snow so several are closed and other have very limited operations. Winds are still strong today with gusts in the 40 - 50 MPH range out of the Southwest and temps are cold in the low 20's. 

You can see for additional precip there won't be too much:

That's enough for another 3 - 5 inches of snow in the Big Bear Mtns. And a couple inches on top of what already fell today in the San Gabriel's.

The totals for Thursday morning will be impressive. I'm sure that all of the mtns will either be over 3 FT or very close to it. 

Thursday - Sunday 

The snow showers will end Thursday morning and the skies will finally part so that we can see the sun. Temps will remain quite cool through Sunday with highs in the upper 20's and low 30's. We are likely to see some clouds and mostly sunny skies during this time period. There's a chance we could see a snow shower on Saturday but accumulations would be in the dusting to 1 inch range. 

Winds should also remain light during this time period with gusts only up to 25 MPH out of the West and Northwest. 

Overall it will be a quiet period with mostly sunny weather. Lots of great days to get out on the mtns and enjoy all this amazing fresh snow! 

Extended Forecast

Both the European and GFS Ensembles below suggest we could see another weak storm the middle of next week. 

You can see the Euro is slightly more aggressive but overall neither show a very strong storm. The pattern will be evolving into one where we see cut off lows and they can stall off the coast, like we've seen. But they can also miss up entirely. Hard to say exactly what will happen but I have a good hunch that we'll see another storm or 2 in April. 

Till the next one... Mike out.
