Some interesting observations about upcoming weather for the Philadelphia area—

  • The rain now expected Thursday into Friday morning was not really picked up by the models until two days ago.  The exception was the new FV3-GFS, which predicted the coastal storm almost two days before the other models jumped on board.  (The ‘exclusive forecast’ from one of the TV stations was predicting a full week of dry weather just last weekend.)
  • This upcoming weekend, especially Friday through Saturday, will be anything but Spring-like.  Windy conditions and unseasonably cold temperatures are expected, especially on Saturday.
  • The FV3-GFS is predicting a very cold outbreak Monday night into Wednesday next week.  Included is a possible changeover from rain to snow late Monday into Monday evening.  Maybe an outlier of a forecast, but something to watch, considering the model’s success this week.
