DAYS 1-5 (JUNE 7-11)<\/p>\n\n\n\n
The same old story … upper level low pressure in control. It stays this way until the weekend, when the one over us now finally moves away. Before that, we have a few more unsettled days to go through with shower threats. None of these are “rainy” days, but all contain the chance of rain at some point for at least parts of our region. The upper level low with its center currently to our northeast elongates east-west today then the western lobe begins to drift southward across the region by Thursday and into Friday as the low then reconfigures to more of a symmetrical round shape, centered right across eastern New England and the Gulf of Maine by early Friday, after which it will begin a drift to the east with the last of its effect departing on Saturday. Today’s shower threat comes to northern areas from mid level moisture associated directly with the elongating low, with a swath of wet weather already taking place as I write this in south central and southeastern NH to northeastern MA. Enough solar heating takes place before that to fire up some diurnal showers especially in MA which will move to the southeast, fading later on as the solar fuel diminishes. These will not be widespread for coverage, but can be moderate to briefly heavy where they do occur. You’ll also notice that our thick smoke plume from yesterday is less so as it gets pushed to the south, although it may hang on in CT longer. The plume should then be kept mostly out of the region by the upper low into late week. Another round of diurnal shower development takes place Thursday, and with a little more northeast-southwest orientation of upper low and resultant mid level southwest wind over our area, we may see one or two broken lines of showers and embedded thunderstorms in the region. The threat will be a little higher in southeastern MA tomorrow over today, but they can occur anywhere else in the region as well depending on where the initial development takes place. Another region vulnerable may favor northeastern CT, central MA, and southern NH with tomorrow’s activity, with a late-day fading of activity again. Friday, with the core of the cold air aloft right over us, you’d think that the showers and storms could pop anywhere and everywhere, but at the surface with light winds we may develop a moderate sea breeze which may have a stabilizing influence at least in the coastal plain, keeping shower activity limited or even prevented, with activity focusing more on the inland hilly terrain from southwestern NH through central MA into northeastern CT and northwestern RI. Will monitor this trend on short range guidance. Of diurnal shower\/storm development the next 3 days, Friday’s has the greatest chance to produce hail where it occurs. Saturday looks “better” but enough cold air will remain over the region on the western edge of the departing low that we will at least pop some clouds and maybe a few more showers, but these should be limited and may peak quickly around midday. I’ll have to fine-tune that part of the forecast as we get closer to it. By Sunday, that upper low is gone and we’re in a weak ridge of high pressure between it and the next approaching trough, so we get a very nice day. But the next trough may already be spreading high and mid level clouds in by later in the day, so we may not end up with a completely sunny day Sunday.<\/p>\n\n\n\n
TODAY: Smoke-filtered sun southern MA southward early, brighter sun just to the north, and thicker clouds northeastern MA and southern NH with showers into mid morning. Afterward variably cloudy with scattered midday and afternoon showers favoring MA but possible anywhere. Highs 61-68. Wind NW 5-15 MPH.<\/p>\n\n\n\n
TONIGHT: Lots of clouds. Maybe a shower early. Lows 48-55. Wind NW up to 10 MPH.<\/p>\n\n\n\n
THURSDAY: Variably cloudy. Chance of showers and possibly a thunderstorm. Highs 61-68. Wind WNW 5-15 MPH.<\/p>\n\n\n\n
THURSDAY NIGHT: Partly cloudy. Lows 47-54. Wind WNW 5-15 MPH.<\/p>\n\n\n\n
FRIDAY: Partly sunny. Scattered afternoon showers and possible thunderstorms, favoring areas away from the coast. Any storms can produce small hail. Highs 62-69. Wind variable up to 10 MPH with coastal sea breezes.<\/p>\n\n\n\n
FRIDAY NIGHT: Partly cloudy. Chance of a shower early. Lows 48-55. Wind W up to 10 MPH.<\/p>\n\n\n\n
SATURDAY: Partly cloudy. Chance of a few midday showers favoring the eastern coastal plain. Highs 67-74. Wind variable to W up to 10 MPH.<\/p>\n\n\n\n
SATURDAY NIGHT: Partly cloudy. Lows 50-57. Wind NW under 10 MPH.<\/p>\n\n\n\n
SUNDAY: Sunshine. Increasing clouds later. Highs 70-77, coolest coast. Wind W up to 10 MPH, may be some coastal sea breezes.<\/p>\n\n\n\n
DAYS 6-10 (JUNE 12-16)<\/p>\n\n\n\n
Large scale pattern again dominated by a low pressure trough with unsettled weather weighted toward the first half of next week. Temperatures near to below normal.<\/p>\n\n\n\n
DAYS 11-15 (JUNE 17-21)<\/p>\n\n\n\n
Still a tendency for more trough than ridge at upper levels but relaxing a little so that we’re drier overall and temperatures are more seasonable.<\/p>\n","protected":false},"excerpt":{"rendered":"
