DAYS 1-5 (JUNE 8-12)

High pressure sits centered over the St. Lawrence Valley / Upstate NY to start this week off, and this will provide our region with fair weather and a cooling north to northeast air flow today, and a rather cool night tonight as the high center crests overhead. As it slips off to the south Tuesday, a return flow from the west will warm us up off a cool start – so we’ll see about a 30-degree diurnal on average in much of the region (from 50s to 80s in general), though parts of the South Coast and Cape Cod will be cooler due to wind partially off the ocean water. We also get to enjoy another day of abundant sun and low humidity. After this, things change heading into late week. High pressure remains anchored to our south, just off the Mid Atlantic Coast, during midweek. This will increase our humidity and keep it quite warm. Meanwhile, a weak trough will approach from the west, bringing shower and thunderstorm chances to the region starting Wednesday afternoon and continuing through Thursday. This is not to say we end up with a day and a half of rain – far from it, in fact. During this time, two or three rounds of showers and storms are possible with the majority many hours free of any rainfall. If you have outdoor plans, you will want to keep track of what’s going on. This trough departs the region Thursday night. During Friday, while we have drier weather in place, a little push of high pressure extending from Atlantic Canada will cool coastal areas down while it is notably warmer over inland locations. This is a day 5 expectation, so check updates during the week just in case anything changes with this part of the outlook.

TODAY: Sun and passing clouds. Highs 67-74 I-95 belt / coast, 74-81 interior. Wind N to NE 5-15 MPH, gusts up to 20 MPH especially east-facing shores.

DAYS 6-10 (JUNE 13-17)

High pressure to the south becomes more dominant for the June 13-14 weekend while a weak trough passes through the region June 13 with the slight chance of a few isolated showers and thunderstorms, then a more notable cold front approaches later June 14 with a better shower / thunderstorm chance. Briefly fair after that, but unsettled weather chances increase with an approaching trough toward the middle of next week.

DAYS 11-15 (JUNE 18-22)

There’s some uncertainty remaining out this far in the prognostication attempt where we’ve seen mixed pattern signals and inconsistent guidance. In a general sense, I lean toward unsettled weather chances highest at start of and end of period with fair weather between. There may be a little bit of heat to say goodbye to astronomical spring and welcome the “official” start of summer over the June 20-21 weekend. The summer solstice occurs at 4:24 a.m. EDT on June 21.
