DAYS 1-5 (MAY 31-JUNE 4)
Patterns can be unsettled and not overly wet (amount-wise). That’s what we’ve had for months. Big picture, not individual events. That’s what we have coming up in the shorter term. Unsettled pattern, but not a lot of rain. But don’t key on the word unsettled. Let’s first focus on what will be 2 very nice days today and Saturday as high pressure controls the weather today and hangs on into Saturday as a front approaches from the west. This front will run out of steam and so will probably all the showers it tries to throw our way. As a second front pushes toward the region Sunday, a lot of its shower and thunderstorm activity may also be held at bay to the north and west of the majority of the WHW forecast area. The irony: that ocean-cooled air that so many people can be annoyed with at this time of year will be a big part of the reason the wet weather doesn’t make it into places like Boston and Providence. Now how about that! Eventually, the upper level energy will win out and we should get showers further south and east by later Sunday and Sunday night, so the weekend may end wetter in the areas it was dry most of the time. Early next week, a late spring upper level cool pool will be overhead and while most of the time it will be dry, we’ll have to watch for pop up instability showers both Monday and Tuesday, with the greater chance likely to be Monday.
TODAY: Mostly sunny. Highs 71-78 except cooler any north or west facing shores. Wind light N then sea breezes.
TONIGHT: Partly cloudy except coastal fog and low clouds. Lows 52-59. Wind light variable.
SATURDAY: Partly sunny. Coastal low clouds and fog may be slow to break in the morning. Highs 67-74, coolest coast. Wind light E to SE.
SATURDAY NIGHT: Mostly cloudy. Slight chance of showers, mainly late-night, favoring areas north and west of Boston. Areas of coastal fog. Lows 53-60. Wind light SE to S.
SUNDAY: Mostly cloudy. Areas of coastal fog and drizzle early to mid morning. Chance of showers mainly very early favoring areas north and west of Boston and again late-day in any location. Highs 62-69. Wind light variable.
SUNDAY NIGHT: Cloudy. Showers likely. Lows 55-62. Wind light variable.
MONDAY: Variably cloudy. Scattered showers possible. Highs 63-70. Wind N 5-15 MPH, higher gusts.
MONDAY NIGHT: Variably cloudy. Scattered showers possible early. Lows 50-57. Wind N 5-15 MPH, higher gusts.
TUESDAY: Partly sunny. Isolated showers possible. Highs 63-70. Wind NW 10-20 MPH, higher gusts possible.
DAYS 6-10 (JUNE 5-9)
Temperatures variable but overall near seasonable. The mean trough position will likely be in eastern Canada with a ridge to the west (Midwest / Great Lakes). This pattern will send disturbances southeastward across New England and bring a few opportunities for showers.
DAYS 11-15 (JUNE 10-14)
I’m staying with the idea of pattern persistence in this period even though some medium range guidance tries to build more of a ridge of high pressure in the East. Still the overall feeling is when this pattern is ready to let go, it will do so quickly, so making no changes for now, but confidence is not high. Still should have a lack of early heat but a few opportunities for showers.
