January 18: Winter weather forecasts for snow begin to go out on Friday

January 18, 2024

Updated Thursday morning

Today will be a cool and calm day before the next event. With increasing clouds, it may feel cold and it may even appear to be snowing at times. There may be flurries or snow showers this evening or tonight. I’ll focus on snow falling before sunrise on Friday.

Moderate snowfall will likely peak during the morning and into the early afternoon.

This is likely to impact travel and schools, so pay attention to information from your local area.

Updated winter weather warnings

The National Weather Service finally expanded alerts to include Maryland and Virginia. This follows the logic I was sharing and my expectations as well.

Plan for snow to fall before sunrise, with the greatest impact in metro areas during the morning and early afternoon.

A winter storm warning for the high mountains with 6 to 12 inches of snow possible through Saturday.

My first call for snow

Again, I need to play the conservative side here…but I think this may be almost a repeat of last week…maybe a little lighter snow in central and southern Maryland.

The next full update will be between noon and 1 p.m

See NWS and typical snow maps below.

Morning surface weather

There are not many suggestions for our weather event here on the map…. There is a front in the Great Lakes that will help enhance our cloud cover.. and perhaps flurries later in the mountains and northern regions.

The snow event we expect will develop with upper level impact early Friday.

Let’s start with this broader view. Here’s a closer look, snapshots and sample maps of snowfall possibilities.

While the surface low will be far to the east off the coast, there may be an intermediate low developing south of I-95 in southeastern Virginia that could briefly enhance snowfall. This will be a reflection of the jet line/upper level winds that can increase the air height and lower the pressure for expanding snow. Weather forecast for a January 18 snow storm from ECMWF

Friday weather

Radar simulation: 12 a.m. Friday to 12 a.m. Saturday

I see limits of snow in central Maryland and to the north. Farther south will be on the edge and will get some… ending with showers.

The heaviest snow could be across northern Maryland into southern Pennsylvania.

Then snow will continue until Saturday in the high mountains. That combined with the cold temperatures will inflate their total.

NOAA forecast for next week

We will return to a warmer pattern, but it’s all relative. Right now, I’m seeing rain in the 40s on Wednesday and possibly into the 50s by the end of next week. So, colors can be deceiving.

7 day forecast

After this snow event, the wind and cold will continue throughout the weekend.

A slow moderate trend will take us into the warmer storm track to the west.

Paraphrasing my post about dyslexia

I know there are some spelling, grammar mistakes, and other glitches sometimes. I take responsibility for my mistakes and even computer errors that I may have overlooked. I’ve made a few public statements over the years, but if you’re new here, you might have missed it: I have dyslexia and discovered it during my sophomore year at Cornell. This did not stop me from obtaining my degree in meteorology and being the first to obtain an AMS CBM in the Baltimore/Washington area. One of my teachers told me that I had come this far without knowing it and to not let it be a crutch to move forward. That was Mark Wysocki, and he was absolutely right! I miss my mistakes in my proofreading. The autocorrect spell check on my computer sometimes does it unfairly which makes matters worse. I can also make forecasting errors. No one is perfect at predicting the future. All maps and information are accurate. “Verbal” things can get sticky. There was no editor who could check my work When I need it And have it ready to send on a newsworthy timeline. Barbara Werner is a member of the web team who helps me maintain this site. She has taken it upon herself to correct typos when available. It could be after reading this. I accept this and perhaps it proves that what you read is really from me…it’s part of my appeal. #FITF
