**Winter Hail in SW Ontario!** We have received numerous hail reports from last night's (Feb 18) thunderstorms in SW Ontario, w/ the largest est hail size from the Brigden area at ~24 mm. Hail reported in several other locations (London, St Thomas, Strathroy) was generally smaller ~5 to 10 mm. 1/3

7pm measurement at downtown Toronto: 44 cm storm total. Also measured a snow-meltwater ratio of 30:1 (!). Heavy snow, poor visibility and strong winds continue under the persistent LE band.

*CSSL Summer Internship - Applications Closing Soon* For those still interested in applying to the CSSL summer internship program, you still have until Monday, January 26, to get your applications in! Details and application forms located here: www.uwo.ca/cssl/interns...

*Important announcement!* CSSL Summer Internship Program applications are now live! Spend the summer chasing hailstorms, documenting tornado impacts, and contributing to world-class storms research. Details and applications located here: uwo.ca/cssl/interns... Applications close January 26th.

Excited to announce that my method for estimating wind speeds based on lofted debris in tornadoes was used as contextual evidence for upgrading the Enderlin, ND tornado to an EF5! doi.org/10.1175/MWR-... #NDwx #Enderlin #EF5 #Tornado

“Scientists-turned-storm chasers” are tracking down Alberta hail storms to better understand how to protect against them. Researchers from the Canadian Severe Storms Laboratory ( @cssl.ca ) at #WesternU spoke with the @theglobeandmail.com about the Northern Hail Project.

**Seeking Hail Reports: Calgary was affected by a potentially damaging hailstorm this evening (July 13) between 7:45 & 8:15 PM MT, tracking SE from the NW corner of the city to S of Chestermere. Please send us your hail and hail damage reports, and if you can, save some samples! #abstorm #Calgary

**Survey Announcement: Yesterday (July 9), NHP Field Ops intercepted a damaging thunderstorm near the communities of Acme & Carbon, AB. A damage survey of the combined impacts of wind & hail in the area will be conducted later today. Let us know if you have any information on this storm! #abstorm

These platforms, Super Mobile Hail Observatories (SuMHOs), will be deployed by members of the NHP field team across the US plains during the #ICECHIP field campaign. ICECHIP endeavours to improve radar-based #hail detection, hail models and forecasting, and hail warnings. @nsficechip.bsky.social

The NHP has been busy preparing for field operations, both at home and abroad! For the #ICECHIP field campaign, the NHP and Western's UMS designed and built 4 platforms which collect and preserve hailstones, capture high-speed video of falling #hail, and measure hail fall speed with a small radar.

Dive into real-world research and fieldwork with the CSSL Summer Internship Program! Learn more and apply here: uwo.ca/cssl/internships/index.html Don't miss your chance to gain hands-on experience with leading hail and tornado experts in the field. Applications close on January 27th.

The Canadian Severe Storms Laboratory has launched 🚀. Backed by 60 years of expertise in #wind engineering—and a $20M gift from ImpactWX—it will revolutionize how we understand Canada’s most extreme #weather. At our new website, cssl.ca, you can watch a recording of the first CSSL Symposium.
