phlwx Posted June 13, 2013 Share Posted June 13, 2013 For the scorecard -- GFS still shows warm front breaking Philly, NAM gets it right to the city (temps get to 81/82 on raw NAM, upper 70's on MOS). With the thunder threat pushing in this morning, it's going to be a messy forecast on temperatures and a likely close call on the city itself. I think north of the city is more a heavy rain threat, south/southwest of the city is probably the best spot for severe. Link to comment Share on other sites More sharing options...

Minnesota Meso Posted June 13, 2013 Share Posted June 13, 2013 For the scorecard -- GFS still shows warm front breaking Philly, NAM gets it right to the city (temps get to 81/82 on raw NAM, upper 70's on MOS).

I think north of the city is more a heavy rain threat, south/southwest of the city is probably the best spot for severe. The US Open golf tourney is in jeopardy regarding their 1st round of play, if early morning convection is minor, it may still rain enough to delay things, if the convection allowing models (cam's) are right, there may be some damage this morning, with another round of strong storms late in the afternoon, if the players get out at all, it may be without a gallery to follow them...they can get the players off the course quickly, but the fans is a different thing.

I can't see them not allowing a gallery out there given it's the US Open...but I can see them calling the gallery off pretty quickly (logistics on parking, transit down there are pretty crappy since there's not a lot of parking and most of the attendees are taking buses from lots 15 miles away). Going to be tough to get everyone through 18 today regardless (IMO). Course is in crappy shape (at least by pro standards) and this morning's rains will not help much.

Boch23 Posted June 13, 2013 Share Posted June 13, 2013 At this point i'm just looking for an actual thunderstorm to move through. Not heavy rain with a rumble or 2 of thunder. Which is all I've seen this year.Also 90% of delco is in Mod Risk or maybe is more accurate. Link to comment Share on other sites More sharing options...
