We arrived on site with 2 mm of snow on the MRR which was brushed off close to 1554 UTC. This day our forecaster for the day (Stephen) had warned us of some instability which could cause some cells to pop up. He was indeed right! This gave Selina and myself (Juris) the perfect opportunity to conduct our first official carsonde on the Nipika side. To the west we noticed convective clouds and what looked like snow to be occurring. Selina and I were ready for the chase (figuratively speaking of course!). We did eventually find a road with a steep elevation gradient. We were safely able to make it up and found heavy graupel.In fact, Hadleigh and Mathieu heard thunder in the valley while we were gone. Moreover, while we were gone, lots of housekeeping was done at the Nipika site. Hadleigh made rails for the solar panel and Mathieu tidied up the trailer.
May 3 - More clean up
Today Hadleigh and Juris stayed at Radium Hot Springs to run some errands while Selina and Mathieu went to Nipika to take observations as the first true comparison between both sites. Believe it or not, Nipika was mostly sunny with some cumulus passing over. Meanwhile Fortress had snow!
A bigger storm is coming however and we feel well prepared!

May 3 After a well deserved break yesterday, we are back at it today!
André & I (Hilary) drove up to Fortress while Charlie & Cécile stayed behind to catch up on data transfer and other important tasks. There was rain on the way over to Fortress from BGI, so we did a carsonde on the way up. The rain was pretty light and became light snow as we drove to the top – hopefully we were able to catch the transition zone. Once we got to the top, snow was light for the whole time we were there. The sun even came out for the last couple of hours - it was so nice to see!
When we were taking snow depth and SWE measurements, we noticed that SWE was very high; our highest measurement of the day was 81mm! This could be due to melting and lateral flow into the area.
We changed sd cards and charged batteries to get ready for a potential big storm coming this weekend. Should be a very exciting and busy weekend! -Hilary
