Wednesday Evening February 27 2019
Do you know the expression that ifs you look hard enough you can find anything you want on the internet? That applies to everything, even news. We have the now with the weather. It will snow on Friday morning and there may be some impact on travel. But what I have to share below is truly one of the most obscure wide ranges of possibilities with a little event I have ever seen.
Friday Snow Notes
🛑Not a major storm.
📏Dusting to 2 inches, mostly early morning Friday
🍌Stikcage on roads possible Friday morning in metro areas.
🚌School delays possible❓
❄️Ends by mid-day Friday with melting after noon.
Compare the model timelines and then see the spread of snowfall maps from each below. The GFS Model Slider and Snowfall Maps are new.. below.
Note: The GFS is on the low end and the Canadian is on the way-way high end. The NAM 3 Km Model has dropped it’s snow forecast from the morning to the afternoon run. So once again, the European ECMWF is the most consistent… But you can find whatever you want in the breakdown below.
Friday Morning Snow Timelines
NAM 3 Km —> slider
- This model primarily shows snow around metro Baltimore to the upper Eastern Shore’s Kent and Cecil Counties.
- Most done quickly by sunrise
- This model keeps the bulk south York.
- Washington and Annapolis start with snow and turn to a slushy mix with marginal temperatures.
Friday Morning Temperatures
Stickage very likely around Baltimore and north, including Eastern Shore’s Kent and Cecil Counties.
Marginal stickage or wet roads between Washington DC to Annapolis.

Snowfall Forecast Maps
The European Model has been the most reliable… It has come up a little with snowfall.
The top spot around metro Baltimore between 2 and 3 inches. Less north by the PA line
NAM 3 Km Model
The NAM Model has lowered in the most recent run, but is more realistic…
Older (morning) run
Newer (afternoon) run
Dropped Baltimore from 5 inches to 2 inches
Canadian GEM Model
The way-WAY- High Total
Honestly, I think 7 inches is ridiculous with this set up
The low end is within reason, but definitely the bottom of the pack. This should add credit to at least getting something for most of the region.
Often with seeing a model spread like this, we toss out the extremes and then take an average of what is left. That is why I feel remaining with a range of a dusting to 2 inches is on the safe side.
I will post my formal call for snowfall tomorrow.
