Uncertainty After Tomorrow

We're about 48 hours out from the first of what looks like two storm systems this week...and computer modeling differs quite a bit over details on what ultimately falls for the region on Wednesday afternoon and evening.

First, the NAM and GFS (the GFS is shown below) are suggesting nothing of note around the region -- with just a few lite showers on the GFS south/west of the city as the storm takes on a suppressed track off of the Carolinas.   If the GFS and NAM are ultimately right Wednesday will just be cloudy with perhaps little more than a few drops/flakes/drizzle in the evening hours as the limited moisture crosses the region.   Steadier precipitation would fall from Dover on south, in line with what ultimately happened early Sunday morning across the Delmarva.

The GFS and NAM are in agreement around a modest...or nothing event...however, the Euro is still rather potent with the low, spinning it up into a stronger system and thereby throwing more moisture into the region.   The potential for late afternoon through evening rain and snow mixed is still in play on the Euro, with rain from the city on south and probably some wet snow mixing in, perhaps even accumulating briefly, across the north and west suburbs if the Euro is right.    We're not talking major accumulations but an inch, perhaps two if the Euro is right.

The first storm may ultimately play into how the second storm develops and tracks. Computer guidance is equally waffling over the second storm on Friday, with the Euro playing down this storm (generally light precipitation, a "meh" event that probably doesn't even delay the game) while the GFS plays up the second storm into a two wave event...first wave on Friday morning, second wave on Friday night and Saturday morning.   The first wave brings rain to the region, with Saturday's wave possibly bringing some snow to the Lehigh Valley and Poconos.  

Friday doesn't look the best of weather days regardless of the final forecast -- it does look unsettled at best with mainly cloudy skies in the best case scenario, rainy in the worst case.  In between, it could be a drop dodge during the game but nothing that could prevent a game from taking place....just not in the nicest of weather situations.
