A good day to errands done early south & west
Overall, it's a fair storm on the way. Since this is the first one for the heavily populated areas, that makes it a bit more interesting, but it is the weekend and there has been fair notice given. For northern and eastern areas, precipitation holds off until later in the day, so there is plenty of time to get errands done there. Not much wind for most of the region today. It is on track to pick up along the coast tonight as low pressure kicks up a northeast breeze.
Timing / snowfall amounts
Saturday 6 AM to Sunday 6 AM - Steady precipitation appears to hold off for southern and western areas until around midday, although there is a chance of a light rain or snow shower before noon. Precipitation spreads into southern and western areas in the afternoon, and into the north and east into the evening.
Mixing of rain, freezing rain and sleet is possible along the southwest coast and MidCoast shoreline areas.
Sunday 6 AM to 9 PM - Precipitation ends from west to east Sunday morning into the afternoon. Shoreline areas run the risk of a brief period of freezing rain / drizzle before a northwest wind picks up and clears the moisture out.
Track is key for the precipitation type along the shorelines as any subtle jog to the north or south along a stalled front may alter amounts. A cooler, more southerly jog brings 6-9" to the shorelines. A warmer, more northerly jog cuts down accumulations.
Snow to water ratios will be higher for the north and mountains (12 to 14:1) which makes it more in the form of powder there. For the south (6 to 8:1) it appears heavier and wetter.
Bust potential for the coast appears in the form of a more northerly track which brings in warmer air and knocks totals down. For western interior areas, a potential for a dry slot exists which may alter totals down there. For the north, a more northerly track may add to the totals to the rooftop.
