Snow showers in the morning then a cold and windy afternoon


Saturday February 5 – Morning report

As you slept, cold air crept in and was followed by flurries. That shouldn’t be too much of a surprise. I mentioned the higher level energy following the storm, just that it came a little early.

This opens us up to the heart of the cold air, which we can see in two radar loops below.

While next week will return to near and above average temperatures, mid-February is expected to turn cold and wintry again.


  • Morning: Snow showers
  • Afternoon: windy and cold
  • Next week: warming temperatures
  • Return of winter weather in the middle of the month with disturbance of the polar vortex

Doppler radar loop (1 of 2)

3 a.m. to 5 a.m.

Here we can see an enhanced snow line as it moved across central Maryland. It was the main trough and it may have dropped a light dusting of snow on the ground.

5:45 a.m. to 7:10 a.m.

The pattern here is different, showing the ringing of showers and possible squalls. These bands are more spread out, but can also deposit a layer of snow on the ground and the roadway. Temperatures are cold enough to support it now.

Radar snapshot at 7:15 a.m.

Flurries spread across central Maryland at sunrise. This can drop a blanket of snow on the ground around the Baltimore Beltway in Howard County and can reach BWI all the way to Annapolis.

Morning setup

Off the east coast goes the old front and the storm that crosses the country. We are now in a cold pattern, marked by snow showers this morning. Winds will remain gusty and we cannot rule out further flurries or flurries.

The frost has reached the beaches.

There is still a chance for some light showers nearby, most likely over Delmarva. The best chance of showers or steady light rain will be Monday evening through Tuesday morning.

Look forward

Winter has more in store…

In the middle of the month, we will see another push of arctic air into the jet stream. We might start to see this develop at the end of the net week, leading up to Valentine’s Day.

This is the Jet Stream European Loop

No promises for Valentine’s Day in particular, but it’s in the window for the wintry weather to pay a visit.

A “stretched” polar vortex is the disturbance we need to send arctic air our way

7-day forecast

Next week will be slightly above the seasonal norm. I will watch Friday for any adjustment of cooler air arriving earlier, then the return of true winter cold in the following week.

*Disclaimer due to frequently asked questions:

I know there are spelling and grammatical errors. I’ve made a few public statements over the years, but if you’re new here, you might have missed it:

I’m dyslexic and discovered it in my sophomore year at Cornell. That didn’t stop me from getting my meteorology degree and being the first to get the AMS CBM in the Baltimore/Washington area.

I miss my mistakes in my own proofreading. The automatic spell check on my computer sometimes does an injustice to make matters worse.

All maps and information are accurate. “Word” stuff can get sticky.

There is no editor who can verify my work when I need it and have it ready to ship on a newsworthy schedule.

I accept this and maybe prove that what you read is really mine…

It’s part of my charm.
