DAYS 1-5 (APRIL 7-11)
A long stretch of dry weather begins today, but some changes still occur. First, we start today with a blanket of cloud cover over southeastern portions of the region as the cold front that went through slides offshore and a southwesterly air flow aloft still keeps the clouds from departing quickly. AS this cloud deck moves off, the sun’s heating will trigger the development of fair weather clouds as colder air moves in aloft, associated with an upper level trough of low pressure swinging through the region. Also, watch for the wind to kick up nicely behind the cold front aided by both pressure gradient between Great Lakes high pressure and Canadian low pressure, and the mixing of the air mass due to the sun’s heating. Increased wind and dry weather also results in elevated brush fire danger. While this is ongoing, a cool air mass will be settling in and set us up for a fair but cool weekend with less wind as high pressure moves closer. A general northwesterly breeze is expected Saturday and with lighter winds on Sunday we can see the development of coastal sea breezes, but both days will feature plenty of sun. The sunnier pattern continues into early next week, and as high pressure sinks to the south and an upper level high pressure ridge becomes dominant, we’ll undergo a nice warm-up.
TODAY: Sun/cloud mix. Highs 52-59. Wind NW increasing to 15-25 MPH, gusts 30-40 MPH at times especially this afternoon.
TONIGHT: Clearing. Lows 26-33. Wind NW decreasing to 10-20 MPH.
SATURDAY: Mostly sunny. Highs 48-55. Wind NW 5-15 MPH.
SATURDAY NIGHT: Clear. Lows 31-38. Wind N up to 10 MPH.
SUNDAY: Sunny. Highs 50-57, coolest coast. Wind N up to 10 MPH except coastal sea breezes by afternoon.
SUNDAY NIGHT: Mostly clear. Lows 33-40. Wind W up to 10 MPH.
MONDAY: Mostly sunny. Highs 58-65, cooler Cape Cod. Wind W 5-15 MPH.
MONDAY NIGHT: Mostly clear. Lows 38-45. Wind W up to 10 MPH.
TUESDAY: Mostly sunny. Highs 61-68, cooler Cape Cod. Wind W 5-15 MPH.
DAYS 6-10 (APRIL 12-16)
High pressure remains dominant with continued above normal temperatures through mid period, then watch for Canadian high pressure to send a frontal boundary southward with a April 15-16 weekend cool-down. Generally dry weather is expected but may have to watch for a little unsettled weather by the very end of the period if a disturbance is present in coincidence with that frontal boundary.
DAYS 11-15 (APRIL 17-21)
During this period we become more vulnerable to a trough / disturbance from the west with increased chances for showers a couple times, but too soon to really time-detail anything. Temperatures somewhat variable, overall close to normal.
