I seem to have the image of a cartoon character walking one way while his upper body moves in the other direction.
In addition, a large cell just popped up 5 miles south of Islip 20 minutes ago, and while it's growing in size it's remaining in place. There's a good chance of precip from it hitting the mainland, but it's also not moving with the bulk of the main storm. Figures.
The main batch of precip has two areas of movement: the main in Brooklyn is slowly sweeping east, the second is swinging up north towards Islip, but is also rotating CCW as it moves north up the Atlantic, and the cross winds are stretching it out and leaving the heaviest showers/storms offshore and possibly east as it drifts towards Suffolk.
The upper level winds from the jet seem to be trying their hardest to move the system east, but turbulent eddies dropping down from it to the surface are causing it to stall.
The rotation is seeming to edge out the drifting though and the south edge of Nassau/Suffolk (barring what's happening with that small cell 5 miles south) 2PM seems to be time the main precip swings over for the South short, more towards the north. Will keep an eye out on the storm in the short-term, in fact in writing this another tick on the timeline just occurred on the radar moving the north part of the system half a mile more south.
Sometimes I don't know if the weather even knows what it wants to do.
