On Monday Baltimore’s BWI hit 70F in a November that has had temperatures well above normal. Payback is on the way, but there could be one more last run a that elusive number on the thermometer. First, a shift of the winds form the east will make it much cooler that with mid 50s to near 60F. Clouds build in ahead of the large storm that is bringing raging blizzard in Colorado and severe storms with tornadoes in the south. It’s the storm line we need to watch for Thursday morning, then the cold air that could bring snow showers and flurries this weekend. Compare that this Sunday to last week’s Ravens game when it was 64F.
A flip of the jet stream is what we will notice by the end of the weekend. This plot shows the dip or trough shifting to the eastern US, which will adjust our temperatures to a below normal pattern into Thanksgiving week.
The heaviest rain will pass through Thursday morning, then move out in the afternoon.
