Wind Advisory Tuesday From Major East Coast Storm

March 13, 2023

Monday Afternoon Update

The largest winter storm of the season is now under development. This Nor’easter is going to be a very strong weather event with a large impact across the North East and Mid Atlantic regions. Inland areas will have blizzard conditions. Regardless of where the snow or rain reaches, the wind will be the main player for our region.

The pressure gradient of the new storm will produce increasing winds on Tuesday into Wednesday with gusts up to 50 mph. As a result, a Wind Advisory has been issued in Maryland, Pennyslvania and Delaware.

Wind Advisory Tuesday to Wednesday

There is some fluctuation of the timing between the National Weather Service Office Zones, but essentially our entire region will have winds over 30 mph, with gusts to 50 mph. This may produce downed trees and power outages.

Wind Forecast Snapshot

Strong winds from the Northwest will average 20 to 40 mph. Gusts will push close to 50 mph… and last all day!

March 13 wind forecast Tuesday morning

Afternoon Surface Weather

Low Pressure is located East of Virginia Beach, VA. This is forecast to swing out to the East and Northeast, influenced by Blocking High Pressure in Nova Scotia. That is a key element that may help this pull back West to the Gulf of Maine as it bottoms out!

Jet Stream: Today Evening to Wednesday Morning

Track the Core Energy passing through southern Pennsylvania on Tuesday morning, then slowing down and nearly stalling for 12 hours just east of Boston.

Jet Stream Snapshot

The Upper Level Low will be just north of Baltimore at this time. That is the reason the storm East of Boston is expected to get pulled back west AND have influence of snow showers plus strong winds into Maryland.

8 PM MON to 8 AM WED – GFS Model

Low Pressure: Watch the wide turn in the Atlantic, then the pull back near Boston. This is in response to the Upper Level closed Low and deep trough.

If this storm nearly stalls or retrogrades farther back to the West, will be the big BUST potential.

March 13 weather storm formation Tuesday GFS


Tuesday Morning Snapshot

Low Pressure EAST of Boston will continue to deepen. The retrograde (pull backward to the WEST) will determine if and when Boston and coastal areas transition from rain to snow.  The large influence of this storm will be felt into the Mid Atlantic.

Snow Showers may push into northern Maryland.

Strong Winds will expand through the region to the Mid Atlantic Coast.

Local Look 

Radar Simulation 8 PM Mon to 8 PM Tue

As we watch the storm crank in New England, the back edge will send snow showers or flurries into northern Maryland on Tuesday Morning.

The influence of the core, ‘comma head’, main precipitation will depend on how far west that Retrograde can make it.

6 AM NAM 3 Km Model

This shows agreement with the HRRR Model. Often the flurries expand to more areas than shown on the model… but not expected to be a travel issue.

I will have more detail about the snow part of this storm. I will include snow forecast for the main impact zone and the potential snow showers for our region.

My REALISTIC Expectations for the COLD OUTLOOK

Winter History: Low Snow And Late Starts

See my research based on Baltimore data since 1883.



I am aware there are some spelling and grammar typos, and occasional other glitches. I take responsibility for my mistakes, and even the computer glitches I may miss.

I have made a few public statements over the years, but if you are new here you may have missed it:

I have dyslexia, and found out during my second year at Cornell University. It didn’t stop me from getting my meteorology degree, and being first to get the AMS CBM in the Baltimore/Washington region. One of my professors told me that I had made it that far without knowing, and to not let it be a crutch going forward. That was Mark Wysocki and he was absolutely correct!

I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse. I also can make mistakes in forecasting. No one is perfect predicting the future.

All of the maps and information are accurate. The ‘wordy’ stuff can get sticky. 

There has been no editor that can check my work when I needed it and have it ready to send out in a newsworthy timeline. Barbara Werner is a member of the web team that helps me maintain this site. She has taken it upon herself to edit typos, when she is able. That could be AFTER you read this.

I accept this and perhaps proves what you read is really from me…

It’s part of my charm.
