The Cold Door is About to Open

The door to the much colder air masses of Canada is about to be opened for the eastern US. That means if you like it warm and humid, you had better enjoy today through Thursday, for the door will swing wide open by Friday morning.

This means there are 3 main subjects to talk about:

1. Warm and Humid: the low-level flow was more off the ocean than I expected today, creating more clouds. But they are eroding slowly. The same could hold true to Tue, although I think they will break up faster. And by Wed the flow should be S or SW and we should have partly to mostly sunny skies.
2. Transition Periods: Thursday and Sunday. Thursday is the first big step. A tropical storm/ hurricane (Matthew) will hit the Gulf Coast (Fla) and be pulled N/NE.  Moisture from it will also be pulled north toward our area ahead of a cold front. It will be a wet day. Some rain will be heavy. The core of the remnants of this storm will likely just miss us to the SE. On Sunday, another front will bring more rain, with moisture from a former hurricane in the NE Pacific. This is the second big step down in temperatures.
3. Temperature Change:  High temperatures will be in the 70’s today through Thu. But will remain int the 50’s for Fri – Sun and remaining in the 40’s for Mon – Wed of next week. The threat for frost is certainly there next week.

Enjoy the unseasonably mild weather. We only have a few days left.
