Good morning! After receiving 13.5″ of snow with yesterday’s storm – essentially a perfect verification of the 10-17″ forecast – cold conditions continue.

Saturday willContinue reading “Friday 12/18/20”

Good morning! Quick tweak to the forecast to account for continued trends favoring a major snowfall. What’s Changed: Not much. I moved the 10″ line further north, and made slight tweaks to the boundaries in southeast Massachusetts. The 10-15″ zone is now a 10-17″ zone. Timing: Snow begins late this evening, just before midnight. TheContinue reading “Wednesday 12/16/20 – AM Update”

Good evening! Quick forecast update to reflect some significant trends throughout the day. What’s Changed: I have increased snow totals for much of the region as a large northward trend in the system’s track has become much more apparent, as the relevant energy has become much better sampled and other small atmospheric pieces fall intoContinue reading “Tuesday 12/15/20: PM Update”

Good morning! With mostly cloudy skies and rain likely this afternoon and evening, expect a high around 42 today with a northeast wind around 5 mph. I’ll have a more complete forecast update hopefully this afternoon or evening, as we are tracking a potential winter storm around the middle of next week. It’s too earlyContinue reading “Saturday 12/12/20 AM Update”

Interesting exercise in marginal-temperature snow setup forecasts today. Myself (and most other forecasters, FWIW) significantly overestimated snow-to-liquid ratios. It already looked as if they would be well under 10:1 with 7:1 or 8:1 seeming more likely, but they ended up somewhere between 3:1 to 6:1 instead, which is why we got glorified water today. AsContinue reading “Sat 12/5/20 – Evening Update re: Forecast Bust”

Good morning! Rain has overspread the region early this morning as forecast. The forecast has become more favorable for higher snowfall amounts; the details are below. Amounts: Expect a swath of 10-15″ for south central New Hampshire into central and interior northeastern Massachusetts, as the heaviest snow bands should set up around here. I haveContinue reading “Saturday 12/5/20 AM Update”
