NorthArlington101 Posted 4 hours ago Share Posted 4 hours ago Quick question for the meteorologists, but after this round initiates will there be back built development? In charge of practice and trying to figure out if I should cancel for the whole day (till 6:15) If I was looking at radar and making the call today I’d ax the practice… it’s a taper day before the meet tomorrow anyway. Good luck! 1 Link to comment Share on other sites More sharing options...

yoda Posted 3 hours ago Share Posted 3 hours ago For Sunday... hmmm Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0227 PM CDT Fri Jun 12 2026 Valid 141200Z - 151200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS SUNDAY ACROSS MUCH OF THE NORTHERN MID ATLANTIC COAST STATES... ...SUMMARY... Severe thunderstorms are possible across the lower Great Lakes and upper Ohio Valley vicinity through much of the northern Mid Atlantic Sunday. ...Discussion... Downstream of initially amplified mid-level ridging offshore of the Pacific coast, models indicate that flow will continue to trend cyclonic east of the Rockies through the Atlantic Seaboard, to the south of a broadening vortex centered near southern Hudson Bay. Within this regime, it appears that notable short wave troughing will pivot east of the Upper Midwest through the southeastern Canadian provinces and Northeast by late Sunday night, accompanied by cyclogenesis across the lower Great Lakes through St. Lawrence Valley vicinity. It appears that this may be preceded by the remnants of an initially fairly notable mesoscale convective vortex, within strengthening westerly flow across the Allegheny/Cumberland Plateau through the northern Mid Atlantic by early Sunday evening. ...Northeast... There remains considerable spread within the latest model output concerning the extent of convective potential for this period. Mostly this appears related pre-frontal low-level moisture return and destabilization across the upper Ohio Valley into the lee of the lower Great Lakes, which could be slowed or impeded by the influence of preceding convective outflow. However, guidance generally suggests that destabilization prior to the arrival of the MCV and belt of enhanced lower/mid-tropospheric wind fields (30-40+ kt) will be sufficient to support potential for organized severe convection east of the Allegheny Mountains through the northern Mid Atlantic by late Sunday afternoon. More substantive strengthening of mid-level wind fields and forcing for ascent appear likely to overspread the pre-frontal environment across parts of the upper Ohio Valley into the lee of the lower Great Lakes region, where it appears increasing model output is now suggesting that the evolving warm sector may become sufficiently unstable to support a risk for organized severe storm development. Damaging wind gusts accompanying organizing lines and/or clusters appear the primary severe hazard, but there also appears at least some potential for a few tornadoes. It is still possible that severe weather probabilities will need to be increased further in later outlook updates for this period. ..Kerr.. 06/12/2026 Link to comment Share on other sites More sharing options...

That cluster which originated near IAD yesterday just went gangbusters as it swung through Fairfax, far southern Montgomery, DC, and Prince Georges County. There was a consistent 60-70kt wind signature for over an hour. Really impressive stuff. Looking back on it, the canary in the coal mine was probably the earlier convection near Pittsburgh going so strong. Link to comment Share on other sites More sharing options...

I seen that cell and it had me concerned. There is alot of overgrowth especially past Branch ave and south of 495. Got to see quite a bit of damage today doing patrols for the utility.

Went up to the Herndon metro parking garage for this one. Got some super neat storm pics as the shelf cloud formed in front of me. Realized it would be nasty checking velocity so I stayed in the garage and recorded a video of it hitting (will be posted later). Could hear the metal signs clanging. Didn’t seem to get the insane winds of IAD but I’m okay with that. 3 Link to comment Share on other sites More sharing options...
