5 Wing Goose Bay was the home base for some interesting NASA research over the last couple months and I got the chance to check it out. The goal: improve winter weather forecasting. Take a look. www.facebook.com/share/v/18aR...

Some wind numbers last night. St. John’s #YYT 137 km/h — new highest since Hurricane Larry (145 km/h, Sep 10, 2021). Also: · Powels Head (Trepassey) clocked 174 km/h, but edge-of-cliff siting may over-enhance. · Hebron Oil Platform (elevated anemometer) hit 172 km/h. #nlwx

Some rainy #nlwx in central & eastern Newfoundland over the past 48 hours 🌧️ — but it appears the area that needed the most got the least. A decent soaking for parts of Central though.

High 30.9°C at St. John's #YYT just 0.1°C short of August monthly record for the airport location. Also brings tally to now 4 days in 2025 reaching 30+°C. Previous highest was 2 days (1944 & 1985). #nlwx 🌡️

=ALL TIME NL HUMIDEX RECORD= Humidex 43 in Twillingate at 2:30 pm makes for highest reliable Humidex value ever officially measured in NL (excluding a couple suspect values in the 1970s in Labrador). Prev highest reliable: 42 (Terra Nova, Sep 10, 2001). #nlwx

Can't beat a little bit of glitter and blue sky.

Wow!

Stephenville is currently the hot spot in Canada. #nlwx

Snow in Paradise as of 9:30pm. 29.9 cm and 16.6 mm water equivalent from my heated rain cone (1.3 cm accumulation in the last hour). Snowboard cleaned off. No more ruler pictures. #NLwx

Snow in Paradise as of 2:30pm. 8.4 cm and 2.4 mm water equivalent from my heated rain cone (3.1 cm accumulation in the last hour). #NLwx

ECCC upgraded to a winter storm warning for the northeast Avalon. The snow is just starting for the southern Avalon and will continue to spread north over the next few hours. Ashley

Prelim snowfall totals from data collected so far. Some may have received small additional accums. 41.1 cm (St. John's East); 41 cm (St. John's #YYT); 38.5 cm (CBS); 38.4 cm (Paradise); 36 cm (Victoria, CBN); 28 cm (Brigus); 28 cm (Bay Roberts); 26 cm (Bonavista); 24 cm (St. Lawrence). #nlwx

We’re at 37 cm. The heaviest snow is now offshore. #nlwx

35 cm reported at St. John’s airport. Snow is starting to wind down but the strong winds will continue for the next few hours. Northwest winds gusting near 70 km/h will continue all day. #nlwx

It’s a snow day! #nlwx

Our first blizzard warning of the year is in place for the Avalon. 20-35+ cm for the Avalon tapering to flurries Monday AM and early afternoon. 10-20 cm for the rest of eastern Newfoundland. NE then NW gusts between 80-110 km/h after midnight through noon. The strongest winds between 3-9 am.

No surprise but January was well above normal across the province which led to more rain and less snow right across the board. Happy Valley-Goose Bay tied for their warmest Jan on record and most were within their top 5, except PAB and Stephenville. #nlwx

Almost the end of January, but finally the first 'decent' snowfall of the season for central and eastern parts of the island. Snow-to-liquid ratios of 15 to 20+ to 1 certainly helped to give the accumulations an extra boost in Central! #nlwx

Picked up another 5.5 cm since 7am, bringing #GanderWest snowfall to 23 cm thru 1:30 pm. Water equivalent 14.8 mm. Still snowing lightly. Will post numbers from around the region later this afternoon. #nlwx

Wow.
