September 28 New Record Low Set And Hurricane Ian Rain Update

Record Weather

September 28, 2022

Wednesday Morning Update 

If there was not a hurricane about to hit the US, the big weather story would be our chill this morning. Baltimore set a new Record Low at BWI with a temperature of 48ºF, breaking the old record set in 1984. Most of the region has dropped into the 40s before sunrise. 

Later today, some showers might develop on our north side. It is Saturday when we will watch the south for rain from Ian, with more rain lasting Sunday into early next week.  That will lead to flooding in parts of our region.

Morning Surface Weather

Our set up includes strong High Pressure to the North and Hurricane Ian to the south. 

It was upgraded to a Category 4 with 155 mph winds this morning.

Long Range Forecast For Ian

GFS Model: Thursday Morning to Tuesday Morning

The track keeps adjusting. The GFS is in line with the latest consensus of Hurricane Ian crossing Florida to the Atlantic, then making a second landfall near the Georgia and South Carolina border. This brings a new track, timing, and more moisture available to push north. 

But High Pressure to our north will block the progress at some point, and turn this back to the coast.

  • Saturday (Wild Card) could bring in the rain or remain dry depending on Ian’s behavior. I would plan for it turn wet for the concert in Ocean City and the Maryland Football hosting Michigan State.
  • Sunday is more likely to be wet, with rain lasting in to Monday. 

Also note: We will be in a chilly air mass, so despite the remains of a tropical system, we should get a chilly rain.

Rainfall Potential: GFS Model

We will apply other models and look to fine tune the amounts as we get closer. So that dry pocket and the numbers overall may still shift.  I would not discount anything yet. 

7 Day Forecast

Rainfall next weekend will depend on how Ian behaves. Slight adjustment to the track up to landfall will determine how strong and how much moisture it can push inland.
