DAYS 1-5 (APRIL 21-25)<\/p>\n\n\n\n
The large scale pattern will be driven by evolving blocking which starts upstream over the Atlantic now. An upper level low that went by our region over the weekend from west to east bringing us showers and t-storms Sunday followed by a breezy, cool day with a few additional showers of rain and frozen precipitation Monday is mostly offshore now. The western extent of this low pressure area is still causing some cloudiness over Cape Cod and the Islands early today, but those will slide to the southeast with time and that area will clear, leaving us with abundant sunshine today under a small high pressure area. Temperatures will remain below normal. Sun quickly dries things out so fire danger is slightly elevated, though less wind (just light wind with coastal sea breezes) will be a limiting factor. As we move from mid through late week, upper level low pressure will sit offshore, even retrograding westward a bit (Thursday) temporarily. Wednesday, an approaching low pressure area from the west will try to push a warm front through, and while it brings a canopy of cloud cover and some precipitation our way, the front never makes it across the region as the larger scale block \/ upper low to east forces it southeastward, passing southwest of our region then being pulled into the circulation of the offshore upper level low pressure area. The latter will spin its way a little closer to our region Thursday into Friday. Each of these days will see the development of diurnal cumulus and stratocumulus clouds. Thursday will be more unstable so that those clouds can build into scattered showers, especially over eastern portions of our region. Saturday can be somewhat similar, but additionally we’ll likely see some increased high and mid level cloudiness as the next system that tries to approach from the west starts to be force southeastward, like its predecessor. This does mean continued below normal temperatures through the end of this week, but after the shower threat of Thursday, I expect precipitation-free conditions Friday and Saturday.<\/p>\n\n\n\n
