DAYS 1-5 (DECEMBER 24-28)<\/p>\n\n\n\n
Not bad today as high pressure slips offshore, and while there will be a lot of clouds around, it will turn milder with a bit of an increase wind before the end of the day – but decent for any day-before-Christmas errands you may have. The well-advertised “event”, which really is going to be a glorified cold frontal passage, will take place Christmas Day, arriving as increasing southerly wind and warming temperatures first during Santa’s visit, peaking as a band of moderate to heavy rain showers, possible thunder, and additional strong wind gusts well into Christmas morning, before the front passes, rain showers taper off, and wind settles back after shifting to west. Yes, wind damage and flooding are both a concern, wind damage and some resultant power outages most especially. Flooding is going to depend on several factors – how much rain, the state of storm drains, quick-filling streams, and structures vulnerable to basement flooding especially when there is snow on the ground. This will vary from place to place, but if you are prone to seeing flooding, please be aware. As far as rainfall amounts, even under 24 hours before the main rain event, the guidance is still not really in agreement on how much will take place, with some short range guidance having amounts under 1.00 inch near the MA East Coast with a bit more to the west and over Cape Cod to the ECMWF (Euro) having widespread 2-3 inch rainfall amounts. At the moment, I side a little more with the lower numbers. Regardless of how much rain falls, thankfully, because of a decent gap of time between the end of the rain and the arrival of below freezing temperatures, we can rule out a flash freeze. However, standing water and any surfaces that don’t dry off or are untreated will end up icing over later Friday night into Saturday morning. The weekend itself will feature cold and dry weather due to Canadian high pressure. The next low pressure system approaches on Monday, with the current thinking is that this low, fairly moisture starved, will head through the Great Lakes bringing a rain\/snow shower risk here by late Monday.<\/p>\n\n\n\n
