I’ve been seeing a lot of hype and wishcasting for June being cold out West. This is simply not the case. Sure, the first week will be normal/slightly below but not for long. Second week of June is looking quite warm/above normal.

Blustery day in #Kelowna, thanks to an upper-level disturbance rounding the Montana low & the favourably-orientated N-NE flow.
So far, gusts up to 30-60 km/h have been observed since late this morning, & should continue through this afternoon before calming this evening.
Showers or rain will continue or remain possible through much of the Southern BC Interior today as well.

Wet and muggy day so far in #Kelowna, as additional, beneficial rainfall passes through! (Currently sitting at 14.4 mm on my PWS)
It should clear out, however, by later this aft or early this eve.
Videos of last night's t-storns will be posted between Sunday & Wednesday.

Storms have moved on, and the warm, steady, beneficial rainfall has moved in, which should work its way through #Kelowna & the Okanagan over the next 2-4 hours or so. 🌧
It wasn't smooth sailing BY FAR, but overall, a relatively successful first thunderstorm event of the year for me 👌.
I need to sleep now. Good night.
(Videos to come later today)

After a week of convective/wet weather, with near seasonal-below seasonal highs between the low double digits to low 20s (a few in the mid-20s some days), sunnier, warmer weather has made its return to #Kelowna & much of Southern BC.
(Photos & videos, including some of the past posts with photos/videos, in order from a couple of Tuesdays ago to yesterday)
Today's lovely "blue marble" shot of the eastern Pacific. As captured by GOES-18 at 2100 UTC / 2 PM Pacific, around the time of maximum disk illumination. Received and processed from the 1.7 GHZ radio signal with my own ground station here in Vancouver. Mostly gear from Nooelec.

Photos & videos from a ~7 km hike I did along the High Rim Trail (E of #Kelowna#BC), from Postill Lake FSR to just past the 21 km point & back, last Tues aft, taking in what was the final very warm, dry day before the...

Today & tmrw, a cold, NW flow with embedded disturbances/shortwaves will impact Southern BC.
Today, in tandem with marginal instability, daytime heating, & weak deep-layer shear, as well as orographic lift, steep lapse rates, & weak SFC features (low(s) &/or trough(s)), this’ll lead to continued isolated-scattered/patchy precip/convection, which has been ongoing since yesterday, with the risk of isolated t-storms from this afternoon, into this evening, across the Interior.
While the Interior t-storm threat & convection will come to a gradual end in the evening, due to a weak SFC system, patchy-widespread precip that'll impact the North Island, North Sunshine Coast, & Central Coast this afternoon will either develop or work its way into & impact the Central Interior, North Thompson, & Columbias this evening through into tmrw morning. Patchy-widespread precip will continue to impact parts of the coast during said time as well.

A very cold, broad area of low pressure (that at times will have two or more areas of circulation), with embedded disturbances/shortwaves in its periphery, will impact Southern BC today, before moving fully out of the region tonight. Then, for the rest of the night tonight & tmrw, a cold, NE-NW flow with potential embedded disturbances/shortwaves will be expected as weak upper ridging moves in.
In tandem with marginal instability, at least marginal heating, & weak deep-layer shear, as well as orographic lift, steep low-level lapse, & weak SFC features (low(s) &/or trough(s)), this’ll lead to continued patchy-widespread precip/convection, which has been ongoing since yesterday, with the risk of isolated-scattered t-storms from now, into this evening, across Southern BC.
While the t-storm threat will end in the evening, patchy-widespread precip/convection will continue through tonight, but gradually diminish with time, with dry conditions (a few, isolated areas of precip/convection possible in the Interior) expected by early Sunday morning across Southern BC.
Isolated-scattered precip/convection will reignite late Sunday morning or early afternoon across Southern BC, continuing through the aft, before gradually diminishing in the eve, with only a few, isolated areas of precip/convection at most expected by midnight. An isolated t-storm threat across the Interior will accompany the precip/convection during the aft-eve period. It'll be driven by the cold upper-level flow with potential embedded disturbances/shortwaves aforementioned, in tandem with marginal instability, at least marginal heating, & marginal deep-layer shear, as well as orographic lift, steep low-level lapse, & weak SFC features (low(s) &/or trough(s)).
Heavy downpours (or snowfall in high elevations), hail or graupel/snow pellets up to 0.25-0.5 inches/~0.5-1.25 cm, and wind gusts up to 50-60 km/h will be the main concerns in non-TSTM/TSTM convection both days. Due to the cold upper-level system & related instability, while lower potential than yesterday, last night, & this morning, funnel clouds/waterspouts will still be possible over the Georgia Strait & waters off the West Island this afternoon.
Overall, across most (if not all) of Southern BC, from early this morning to late tmrw evening, <1-5 mm to up to 15-25 mm of rain is expected.
Both the highest totals, & greatest possibility for locally higher totals (as high as 30-40 mm), will tend to occur where moderate-heavy rain/convection &/or any t-storm(s) pass over (particularly repeatedly).
Meanwhile, thanks to the cold air, for most (if not all) mainland high elevations, <1-5 cm to up to 30-45 cm of snow is expected! The highest totals will reside in the highest peaks of the Coastal Mountains & Koots-Columbias, w/ locally higher totals also possible.
Some lightning & thunderstorm chances across inland Vancouver Island (Victoria/Port Alberni maybe?) with a risk speckled across the Interior as well... all driven by a cool upper trough. #BCStorm
