We start off this Tuesday morning with plenty of low clouds, areas of spotty light showers and drizzle, but overall, the workweek ahead is quiet. Low clouds and drizzle break for some sun this afternoon, although the clouds may hang on tougher for Southeast Mass. Highs today hold near 60 at the coast and warm into the low to mid 60s inland, especially to the northwest of Boston with some sun.
As the high settles in, this week is looking solid from Wednesday to Friday with highs from mid 60s Wednesday to mid 70s Friday.
The 5am advisory for Matthew has winds sustained at 145mph as it’s about to come onshore in southwestern Haiti. Not only is the high wind impact inevitable for the western side of the Country, but giving the fact that a tremendous amount of tropical moisture has to be forced up the mountainous terrain, locally 2 feet or more of rain will create the concern for mudslides.
Beyond Haiti, Matthew takes a run into eastern Cuba by tonight, the Bahamas tomorrow-Thursday and nears the east coast of Florida by Thursday night. Thereafter, by Saturday, Matthew takes a run into/near the Carolina coastline.
There are several factors that’ll play into the track of Matthew in the long range. 1) How strong is the Atlantic ridge (the stronger it is, the more westward it pushes Matthew). 2) The speed of Matthew. 3) The speed and orientation of an incoming trough/cold front from the west. Bottom line we have a long way to go in tracking this storm and track and intensity in the long range will determine how strong the winds are around here and coastal impacts. Regardless, at minimum, rough surf, especially along the south facing coasts of New England is a good bet. The confidence in getting rain has also increased as regardless of exact track, tropical moisture likely gets infused with the front moving in. The rain would most likely be on Sunday, where at least a few inches of rain is possible.
We’ll keep you updated online and on air. @clamberton7 – twitter
