Wednesday Morning Report

The storm today is potent! It will bring snow to a large area of the US, many for the first time this season. Metro Baltimore and the Mid Atlantic will once again be on the edge and mostly rain. We still need to consider the inland suburbs that will get a thump of snow briefly at the start.

If you are in the snow zone locally, the most likely timing is between 9 AM and Noon. If you see snow, stay put and it will melt and turn to all rain this afternoon. What we really need are temps in the upper 20s to near 30ºF for a decent snow event.  With the recent mild weather and barely at freezing, it will take a burst of snow to overwhelm the ground and stick.

Please see my new Profile Map and Forecast Models that help explain the situation.

Headlines

  • Today: Thump of Snow INLAND 9 AM to Noon
  • Brief Stickage Inland
  • Rain Cities: T’Storm This Evening

 

Winter Weather Advisory:

Frederick MD/westward; Southern Pennsylvania!

At this point, the arrival may be 9 AM to Noon, limiting any impact.  The urban and southern areas are likely to be mostly rain, but could get some mix at the very start.

There are colder pockets surrounding these main locations. See the spotlight on Carroll County, MD below.

Local Focus: Carroll County, MD

That Westminster location is deceiving as many areas surrounding the county in all directions are still below freezing.

Morning Surface Weather

Snow has shown up on local radar already in the hills, but not reaching the ground yet.

This is a Winter Storm entity, even if we miss out on the snow. Plenty will fall in the Ohio Valley, Central PA, and New England.

Severe storms will erupt across the Southeast US.

Temperatures at 11 AM

I chose this arbitrary time to highlight the mild trend. So with snow falling, many areas in that zone will be above 32ºF.

A heavy snow THUMP can briefly overtake a warm ground, but patience will allow melting.

Snow/Rain Tracking

Canadian GEM Model

This shows the arrival locally between 10 AM and 1 PM

We still should apply a buffer of 1 to 2 hours for model error (slow)

HRRR Model

I’ve marked up the area where the product still suggests possible edge of snow (slushy).

NAM 3 m Model

12 PM- Noon

This is too late for the arrival in my opinion.

11 PM – Tonight

I chose this product to highlight since it does the best job suggesting the heavy rain and possible thunderstorms.

 

Evening Temperatures

Notice that metro areas area get into the 40s.

Eastern Shore gets into the 50s, with 60s nearby around Norfolk, VA.

 

January 25 weather temperatures Wednesday 11 PM

 

Note:

Yesterday I highlighted the GFS Model with a rare win for timing the snow in Arkansas. Overall, this product is failing and I will limit sharing plots until the problems can be resolved.

Before we blame the ‘American Models’, the NAM 3 Km and HRRR Models are also American. Those are high resolution and best used in the short range for the day of, or even one day ahead.

7 Day Forecast

Brief disturbances will pass through Friday and Sunday, but nothing major in sight. We will continue to see mild weather, then look to the second week of February for the next ‘potential’ push of winter.

That is all the pattern shows us for now.
