our heaviest rains will probably occur sunday night after 00z with the development of a secondary low pressure system

Sunday night looks like slow moving heavy elevated convection with the potential for training of cells.

Monday is looking like more of the same with the instability possibly becoming surface based.

Euro would agree with you guys. 00z euro has 2+ for the area, most of the rain stays to our west during sunday. Sunday night and monday is the bulk..........eastern PA get 3-4 on the euro 00z run

GFS still insisting we get rain all day Sunday with a good .75" by evening. NAM says nothing til early evening. That's a pretty big disparity for less than 48 hours out but I guess par for the course lately.

It has been being discussed, it is just that everyone posts every single thought on everything weather-related in the one August "superthread" within this subforum. It drives me nuts. We already have a subforum, we can branch out the threads a little guys.... arrowheadsmiley.png

I had an all-day beach trip planned for Sunday so seeing the model disparity this close in is a bit disheartening.

the convective nature of this event is bound to screw someone over. with the models now showing weaker secondary development, it might be all of us.

how is a summer rainstorm missing us "screwing us"...winter i get...but rain in the summer...i think if it misses us its a score...

yea, best dynamics could stay west and north of the area. We'll see. NWS has a long discussion on it saying there is alot of flip flopping in the models

Nobody in the thread is rooting for rain lol (maybe yanksfan)

we are discussing the weather and the reality that its going to rain and some models like the srefs/gfs/rgem are showing a good amount of it. It doesnt matter if we want dry and sunny weather.

Very good recipe for hvy rains given the synoptics evolving over the next 48 hours. Upper level s/w trough propagating east, becoming neutral to even slightly negatively tilted by Sunday night. Closed lows at H7 and 850mb however, with surface flow originating in the sub-tropics, providing plenty of moisture feed into the area. So we've got upper level dynamics via the s/w trough, low level convergence via a deep moisture feed off the Atlantic, etc, and H7 vertical velocities are progged to be fairly impressive so I'd think there will be locallized totals higher/much higher than modelling currently suggests. Would not be surprised to see some locations w/ training convection record over 4" of rain while others may only see 1" or less. Overall though it should be a pretty widespread rain event.

Both the 00z NAM, and GFS had the heavy rain further east then previous runs, places the heavier stuff over NJ/NYC metro, 2"+ amounts. Not sure if the Euro would be the model of choice now since we are within 24 hours of the start of the event.

00z euro is a bit wetter for the area 1+.........still keeps the big amounts in eastern PA and upstate Ny.

You can put a vote for rain here also.

Ill take it.

Main reason is to put negative days for the monthly anomaly and I enjoy a good downpour also.

I'll take the rain also. I like long duration rainfalls once in a while.
