TS Henri Radar Update And Simulation For Sunday Afternoon

Tropics

Sunday August 22 2021

Tropical Storm Henri continue to weaken while throwing moisture well west of its path. Winds are down to 60 mph, but there is a lot of rain to spread around.

A weakening and landfalling tropical cyclone will almost always spread out the rain coverage. We get an added boost from upper level forcing to push that rain into our region today, even as the storm moves farther away.

My wife made plans to go for a walk with her friend. I tried to advise them of the rain, but they insist on making a game time decision. 

I figured you may have plans as well, while either watching rain outside or waiting for it to reach you.

This post is focused mainly on the rain. You will find the morning radar loop, latest snapshot, model forecast simulation, and Live Radar widget below.

Flood Potential

There will be some areas that get persistent heavy rain. Flood Advisories will be issued. Already some are posted for Delmarva, already experiencing this.

Regional Composite Radar Loop

The path of Henri is just east of Long Island NY into Rhode Island, but the heavy rain continues to be pulled west and southwest.

Doppler Radar Snapshot

Steady rain has been closer to the center. For us that is northeastern Maryland and Southeastern PA. 

The entire shield of rain is drifting SOUTHWEST into central Maryland.

Cells and bands are moving from Northwest to Southeast.

 

 

HRRR Model Simulation—-> slider

Compare to the Live Radar and Lightning Widget below

This has done a better job than the NAM 3 Km model I have shown in prior reports. 

  • There may still be more rain verified than shown in this simulation.
  • Local tropical downpours can drop rates of 1”/Hr or higher rainfall.

Monday Morning

It looks like a resurgence of rain will fill in across central Maryland and Delmarva, much like a Nor’easter. This snapshot is pre-dawn, but likely to be with us through sunrise.

Sunshine State Of Mind

I am done with the cold and snow (for the season). I am embracing my wife’s mantra of Sunshine State of Mind.

This was designed by Shannon Berk and we will be wearing it through spring and to the beach.

Double Benefit: Proceeds will be split between our nonprofit Just In Power Kids and the development of my new weather website. That has been scheduled to be ready to launch in May.
