Saturday February 3 2018

Arctic air has settled in place this morning but the cruel trick for snow lovers this winter has been the storm track. We have had plenty of cold air and plenty of potential storms advertised days if not more that 1 week ahead. This event on Super Bowl Sunday is one that I held back on considering the lack luster cold front we had on Friday and because I do not like to lock into a Farmer’s Almanac storm forecast. We will get a storm as shown below. I wanted to compare three different computer models that have three different solutions just a day ahead of the event. The only thing they can agree upon is that the timing is Sunday and ending tomorrow night. Here’s a look at how I see it a with my thoughts below:

Sunday Morning


Most of our region will stay at or below freezing through Sunday morning. That does allow for the ground to cool enough to support any winter precipitation to stick


Sunday Morning Warming Winds

The Bay water temperature this morning was 33ºF at Thomas Pt Lighthouse. That is chilly, but still above freezing, and this wind flow Sunday is a deterrent for winter weather in our region…

Sunday Storm?

Compare Three Computer Models

See my thoughts below

  1. GFS (Warmest)- This shows a possible start of snow or sleet, but all rain by noon even into York and Lancaster in PA



2. Canadian Model (Coldest) – This holds the snow line just north of I-95. The reason for this is based on a secondary Low Pressure forming to the south and holding the cold air in place. 




3. NAM 3Km (Compromise) – This model does show enough cold air holding for a few hours of snow and sleet, especially north and west of the cities… but the warm air wins with this one too. In fact, a band of heavy rain with possible rumble of thunder by evening… Then the system moves away before the end of the game.


My thoughts:

While I do love the Canadian Model in arctic patterns, the arctic air is not holding. There is no blocking to the north, which limits the chance for the secondary coastal Low to take hold. That is the main difference, and if it forms we will get more snow to the north.

I can’t buy the warming as quick as the GFS is showing based in the cold bay water and the arctic air in place.

I see the NAM solution as moat likely.. But given the time of day, snow or sleet in the morning might be a little slick, but the mid day and afternoon timing is likely to melt on the pavement. So, a start of snow or sleet in the morning with minor stickage near but especially north/west of I-95 and metro Washington/Baltimore. Looks like less than 1 inch in places that do get stickage. If travel is a problem there it would be in the morning before 10 AM. With the light ‘stuff’, and less of an issue during lunch time and afternoon.


Sorry snow lovers, this does not look like our event.  The outlook stays cold with warming just before Valentines Day. Then another push of cold air for the last week of February.
