I also pulled out the lightning trigger that I left a fresh Alkaline 9V in only to discover it was dead during the storms last Tuesday. So here I am with some rechargeable 9V batts and no lightning but "stormy wx" approaching. The odds were never good for 🌩️ today. #ONwx #ONstorm

You know, if it wasn't 7 degrees outside, and this was a little taller, it would actually probably technically be a LP supercell... not bad for a walk with the dog.

Some latest model output regarding the rainfall potential for SONT till 8AM Sun. There will be some thunderstorms in the mix & at the cold front, higher local amounts in storms. You can see the average tracks of the “rain makers” via the “rain trails” SW-NE tracks. #onwx #onstorm

Afternoon runs of the models show similar pattern of development/direction & amounts of precipitation-Snow/FRZN Rain/IP up north (NONT/NEONT) and heavier showers & scattered storms for the south. Once thru, colder air floods in -changing the showers to flurries #onwx #onstorm

Early NBM Thunder Guidance for the weekend, it only goes out 36hrs, new NBM, once approved, will go out further. Next system will bring the risk if thunderstorms to SONT. Again, I find the deep blue/greens verify well for SONT-just a general observation. #onwx #onstorm

Next system on deck-approaches ON later tonight, similar track, similar weather. Behind this, temps drop as cooler air floods, and looks like another weak Clipper drops in mid-week,-I'm starting to hate that "Clipper term"-after a long, hard, winter full of them😒 #onwx #onstorm

Some early numbers of Precip. totals from the ensembles, thru the weekend thru Mon. 8AM.
Canadian Ens. is the wettest of the lot. These are "mean" numbers, so in the multiple runs sims per model there will be higher/lower values with various individual members. #onwx #onstorm

Last 12 hrs. totals of Radar estimates rainfall (in inches), lot's of local higher amounts (if I zoom in around SONT) due to some embedded storms in the overnight. 0.5in=~12mm & 1.0in.=~25mm. #onwx #onstorm

Man, my sump pump just keeps going, that soil around the house must be so saturated, rare to have it run this much,-especially in a urban environment-where they do everything to get rid of the water. Anyway, Latest radar for SONT, with a 6hrs. history till 6:57 AM #onwx #onstorm

Yeah, the weather sucks today across most of Southern and Eastern Ontario, but the warm front coming in is very sharp and when it passes temperatures will quickly pop up into the 20s in many places. #ONstorm #ONWX

Latest short run of the HRRR (12Z):👇
-Radar 4cast (P-type) from ~now till 2AM Fri. Low risk overall for storms, but a few pop-up/embedded storms would not surprise me. Mainly rain/showers for SONT. #onwx #onstorm
