Good morning. Our moderate snow event is still on track for Friday. Timing is Friday morning through the evening. It looks like the heavier precipitation will arrive around 10-11am tomorrow morning. This setup still has a high degree of volatility meaning we can see last min shift up to the time of the event with the narrow heavier band of snow. I am keeping my forecast from yesterday and I do not have any overwhelming data to change it. I will have a final update at 9pm tonight. It is my best estimate of where this heavy snow can set up at this time.
Lets take a loo at the expected evolution. This storm involves an initial batch of energy that will move offshore early Friday, then a trailing arctic wave that will try to capture part of it causing an extended period of snow for the daytime Friday. These capture situation are very hard to nail down...
Light snow should be in the area around daybreak tomorrow...
By time we approach afternoon it is snowing decent in most areas...
Around 7pm things should start to taper down...
Models are still spread in their precipitation outputs but a good middle ground is what the NAM model has...
Given it will be very cold across northern zones during this event add an inch or two to the amounts to account for higher snow ratios.
Very cold air then settles in for the weekend.
Stay tuned final update tonight around 9pm.
