12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Area Forecast Discussion National Weather Service Boston/Norton MA 134 AM EDT Fri Aug 14 2020
SYNOPSIS. It will remain quite warm into Friday, but less humid as the frontal boundary pushes south of New England. High pressure building across the Canadian Maritimes will result in cooler temperatures this weekend especially across eastern Massachusetts. Low pressure may bring a period of showers sometime Sunday into Monday if it tracks close enough to the region. Regardless, expect mainly dry and seasonably warm afternoons Tuesday through Thursday.
NEAR TERM /UNTIL 6 AM THIS MORNING/.
130 AM Update .
Forecast remains on track on a quiet night weather, with weak high pressure building in from Quebec. Nighttime microphysics satellite imagery shows some patchy fog developing along portions of the south coast but those are expected to stay localized. Rather comfortable sleeping conditions with dew points in the upper 50s to mid 60s away from the South Coast, where dew points remain in the upper 60s to low 70s.
PREVIOUS DISCUSSION .
1030 PM Update .
Forecast is largely on track so only made minor changes to bring near term forecast more in line with current obs and trends.
730 pm Update .
Band of showers/light rain along south coastal New England and Long Island has continued to diminish/dissipate over the past few hours. What light rain is left has been falling out of an mid cloud deck/12kft. We should continue to see a trend of this lingering light rain diminishing during the evening, remaining confined to the south coast of MA/RI and the Cape/Islands. Have a slight chance pop in that area this evening, then dry for the overnight.
SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SATURDAY/. Friday .
Temps likely overachieve tomorrow given deep boundary layer mixing up to 750 mb per model soundings combined with dry soils, expect another warm day with highs in the mid to upper 80s, low 80s across eastern MA in response to NE winds. Post frontal so expecting dry weather however upslope flow across the east slopes of Berks along with some instability may yield a few afternoon showers over western CT/MA.
Otherwise dry weather prevails along with comfortable humidity by Aug standards, with dew pts in the upper 50s to lower 60s, except mid 60s along the south coast. More sunshine across eastern MA/RI with more clouds over the hilly terrain of CT into western-central MA.
Friday night .
Dry/pleasant weather during the evening but overnight as low pres south of New England develops low level NE jet develops over eastern MA with winds increasing to 15-25 mph toward daybreak Saturday. This increasing low level jet will likely bring strato-cu clouds onshore into eastern MA toward morning. Definitely cooler with lows 60-65, upper 50s possible northwest MA.
LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/. 4 PM Update .
Saturday .
A relatively weak rex block extending from the Great Lakes Region into Quebec Saturday morning slowly shifts eastward during the day, with southern New England being more influenced by the associated mid level trough. Looking at the surface pattern, our area is in between a surface high pressure building over the Canadian Maritimes, and low pressure south of New England and east of the Mid Atlantic States. A second low pressure system is located to the west, in the mid Ohio Valley There is model discrepancy on the track of the 2 low pressure systems, and whether or not our area is more influenced by the maritime high or the surface lows.
Either way we will likely have a brisk east/onshore/marine influenced wind, noticeably cooler, with increasing clouds in our area. Across the interior, we have a better chance for breaks of sunshine. The proximity of the low and some short wave energy could result in a few light rain/showers Saturday, with the best chances in the eastern half of our area. Will have low chance/slight chance pops there. Not expecting a washout, mainly dry but cooler weather should prevail. Highs ranging from the 70s to low 80s, warmest in the Connecticut River Valley, coolest near the eastern shoreline. Lows Saturday night in the mid 50s to mid 60s.
Sunday and Monday .
The Rex block moves further east while a deep mid level trough approaches from the west. At the surface, our area continues to be in between high pressure over the Canadian Maritimes and low pressure to our south, as the western most low from Saturday gradually makes its way eastward and off the mid Atlantic coast. Conditions for Sunday into Monday look similar to Saturday, except more guidance is leaning towards mostly cloudy skies with a chance for rain/showers even over the interior. Forecast temps reflect the forecast cloud cover combined with a second day of easterly flow- highs mainly in the 70s and low 80s, lows in the upper 50s and 60s.
Tuesday through Thursday .
Dry weather should prevail during much of this period, with high pressure building in from the west while the mid level trough axis shifts to our northeast. Might be a better chance for showers by Thursday, but a lot of uncertainty at this time. Expecting seasonably warm temperatures during this period.
AVIATION /06Z FRIDAY THROUGH TUESDAY/. Forecaster Confidence Levels .
Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent.
