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.

 

Jet Stream Preview

An Upper Level Low will bring us some rain for a few days, then open up the flow for more frequent cold fronts. See the animation below.

Tropics: Just For Fun

This morning, the headline in the Atlantic is Peter Rose.  Not the baseball player banned from the Hall of Fame, but a pair of storms that might show the sense of humor from the World Meteorological Organization. 

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

Jet Stream

Monday Evening To Sunday Evening

The Upper Level Low responsible for the rain we will get later this week, will also be bringing very chilly air across the Great Lakes.

This is marked on the Jet Stream here in blue. This will start a trend of more ‘cool’ waves to follow.
