A frosty morning across the region. Morning lows to name a few.. 18 Keene, 19 Jaffrey, 17 Orange, 20 Norwood, 21 Bedford, 22 Taunton, 25 Falmouth. If you did not have your scraper out yet…you may want to think about it! High pressure sits over us today with light NE winds and abundant sunshine. Highs climb to 46-50 this afternoon. Another stellar day for this time of year.
Monday will be more of the same with high pressure parked over Maine. Light NE wind will still keep the coast slightly cooler and could lock in a marine layer for the early morning hours for coastal MA with coastal clouds. Otherwise Monday will be another sun-filled day with highs still remaining in the 40′s to near 50 at the south coast.
High pressure sitting over us will help to keep a storm center well south of New England for the midweek. This storm will push off the Carolinas where it will become stronger. Onshore winds and surf will begin to build for the midweek for the Mid-Atlantic states. As the high slowly begins to weaken and pull away Tuesday we will have to watch for increasing clouds and a lowering cloud deck shifting in on the backside of the departing high, along with clouds break off the low to our south. Skies will be their most cloudy by Tuesday afternoon and Much of Wednesday with highs slowly moderating into the lwr 50′s in SNE. No travel problems with weather…I can not promise the roads will be a good.
A weak front will push through Wednesday with an upper level ridge reestablishing itself on the east coast just in time for Thanksgiving. Temps will begin to moderate Thursday and Friday with highs in the Lwr-mid 50′s with dry sunny conditions. Clouds will be on the increase late Friday and for the start of the weekend with a potent front which will pass Saturday with a few showers, which may mix with snow showers in the NW hills. Highs in the 40′s Saturday with temps falling like a rock by Sunday. I expect highs near 40-42 on Sunday with some increasing Sun.
This cool down will be part of a trough swinging into the Northeast. Instead of lifting out, it may be reinforced by another piece of energy digging into it…to keep a colder and more active weather pattern going into early December. The writing is on the wall. Both the NAO and Arctic Oscillation are turning negative heading into December. Some ensembles are showing a dramatic dip. These are signs for more blocking in the atmosphere and the potential for a colder and snowier pattern for December. Much of the eastern half of the nation should expect colder times ahead. Let’s enjoy the quiet for now…for this will not last. This winter should get mighty interesting.
