Wednesday through Thursday: big difference in placement of features with the approaching upper level through to the west. There will be a small chance of showers Wednesday afternoon, becoming likely Wednesday night into Thursday as upper divergence and areas of vertical upward motion approach the area. The GFS has almost no rain overnight Wednesday into Thursday, while the NAM puts around an inch during the same time. Any sun on Thursday will boost temperatures at or above 70F.
Thursday night: Upper trough axis approaches the area with decent upward vertical motion. Showers could get moderate to heavy overnight. Very little instability seen on soundings so no mention of thunder at this time.
Friday and beyond: Surface cyclone moves northeast of the area drying things out and cooling things down quickly by midday Friday. Interestingly, both models are in good agreement with an area of wrap around moisture coming through overnight Friday into Saturday. Could be some snow flakes mixing in at times as the 5400 m thickness line is well south and southeast of the area. GFS has 850 mb temps well below 0C and 925 mb temps around 0C. Otherwise a weak shortwave within the northwest upper flow could bring a small chance of showers Sunday with continued cool conditions.
