Monday September 20 2021
The week ahead starts with a Full Moon today. One year ago today we set the record low temperature in Baltimore.
On Wednesday, the Autumnal Equinox will truly mark the start of a new season. This will be followed by an actual pattern change we all feel by the end of the week.

Neither of these storms will be a threat to the US.
