DAYS 1-5 (MARCH 31 – APRIL 4)
As we end March and begin April, we’ll be impacted by low pressure moving east northeastward and passing north of our region. First, its warm front is moving through early this morning and has produced some spotty light rain/sleet over portions of southern NH which is now moving out. During today we’ll see warmer air moving into the region from south to north, although the South Coast will experience its ocean-modified cooler temperatures with a southerly breeze. There will be lots of clouds but only a few isolated rain showers, with most of the region rain-free during the day. This evening, however, as a cold front starts to approach from the west, we’ll see an increase in rain shower activity, and during a few hours of later evening to early overnight there may be some downpours around and even some embedded thunderstorms. This makes an early Friday morning exit leaving Friday as a fairly mild and mostly rain-free day with a sun/cloud mix, but a chance of a rain shower during the afternoon as a secondary cold front approaches. It is behind this front that we will see legitimate drying and cooling with an increase in wind for Friday night through Saturday. Sunday’s weather has been a bit of a thorn bush to navigate in figuring it out. Low pressure or high pressure in control? That is the question. Well, it does look like we’ll have a fairly weak and moisture-starved low pressure area moving into the region from the west, but right now I’m leaning toward this being more of a cloud producer than a precipitation event, although there may be some spotty light rainfall around at times, favoring the second half of the day and the nighttime hours. This system will likely redevelop offshore, but with the fairly weak and quick-moving nature of the system, any redevelopment would most likely bring brief steadier rain to the South Coast before exiting and leaving us with a sun/cloud mix between departing low pressure and approaching high pressure on Monday. There will still be some fine-tuning needed for Sunday-Monday…

DAYS 6-10 (APRIL 5-9)
Unsettled weather potential is highest in the April 6-8 period based on current timing and expected pattern, which will feature variable temperatures in a battle zone between southeastern US warmth and Canadian cold.
DAYS 11-15 (APRIL 10-14)
Overall pattern similar, typical springtime battle zone. Unsettled weather seems likely at some point, favoring mid period.
