What forecasters said that day
The local office's own words before this gale warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Boston/Norton, MA wrote its last area forecast discussion before this gale warning went out at Nov 11, 1:16 AM EST, 2 hours 5 minutes earlier.
Area forecast discussion, Nov 11, 1:16 AM EST, 2 hours 5 minutes before
Area Forecast Discussion National Weather Service Boston/Norton MA 116 AM EST Wed Nov 11 2020 .SYNOPSIS... High pressure off the coast will continue to bring mild air into the region tonight and Wednesday. A cold front from the Plains swings east, crossing New England Wednesday night bringing a period of showers which linger into Thursday, especially near the south coast. Another system may bring a few showers Friday with much cooler temperatures. High pressure returns Saturday, then a frontal system will bring more showers late Sunday into Monday. Blustery and cool conditions follow Tuesday. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... 110 AM Update... Forecast is on track so no changes made. The Nighttime Microphysics satellite product is showing areas of low stratus and patchy fog moving into the CT River valley. This is associated with the moist air mass with dew points in the mid 50s to low 60s. As expected, the good SW flow is preventing widespread dense fog from developing, though localized dense fog especially in fog-prone valley locations are possible. Temperatures are holding steady in the mid 50s to low 60s overnight. PREVIOUS DISCUSSION... 1020 PM Update... Only made minor changes to bring the near-term forecast with current obs. Overall, a quiet night of weather with anomalously warm temperatures. Overnight lows only drop into the low to mid 50s for most locations thanks to warm air advection bringing dew points in the 50s northwards. With an impressive pressure gradient (1024 mb high to our south and 998 mb low over Wisconsin), it will be quite breezy overnight. This tends to limit the development of dense fog, though locally dense radiation fog could still occur especially in the fog-prone valleys and MA coastal plains. Also watching a deck of low stratus to infiltrate the area by the latter half of tonight, further limiting the extent of radiational cooling. && .SHORT TERM /6 AM THIS MORNING THROUGH 6 PM THURSDAY/... Morning fog dissipates, but is replaced by another low cloud layer. Temperatures of 7-8C at 925 mb suggest one more day of temps reaching the low to mid 70s. A cold front over the Plains will reach NY/PA during the afternoon/evening. The front, and the right entrance region of the upper jet, remain to the west most of the day, so expect most of the day to remain dry. PW values remain low during the morning, but increase to 1.5 inches by 7 PM as tropical moisture from Eta move up the coast. Best chance of rain will be in western MA and CT 4-7pm, increasing all areas during the night. Cold front sweeps through Srn New England Wednesday night, accompanied by venting from the upper jet. PW values leading the front will be 1.5 to 1.75 inches. Dew points forecast in the lower 60s...dew points have been higher, but not by much. The upper venting may support a wave moving up the cold front. All of this should allow for showers through the night, with highest probability south of the Mass Pike. The unseasonable moisture may support local downpours. Total rainfall looks to be in the 0.5 to 1.5 inch range. Mild temperatures are expected due to the high dew points, in the 50s to around 60. && .LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/... Highlights... * Occasional showers Thursday, especially near the south coast * Much cooler Fri with continued risk of a few showers * Dry and seasonably cool Sat * More showers expected late Sunday into Mon * Blustery and cool Tue Thursday into Friday... Cold front will be in the vicinity of the I-95 corridor Thu morning with mild start to the day across RI and eastern MA while cooler temps move into the interior. The front moves off the coast but will likely stall just south of New Eng as a wave develops on the front. Deepest moisture and heaviest rainfall will remain to the south, but enough moisture combined with modest forcing in the right entrance region of the upper jet to support a round of showers, focused south of the Pike and especially near the south coast. Highest PoPs will be along the coast decreasing northward. The rain should exit the coast by evening but a few showers may linger early in the evening over the Cape/Islands. Highs will be in the 60s across eastern MA and RI but falling during the afternoon in post-frontal airmass as winds turn N, with temps remaining in the 50s in the interior. A more amplified shortwave moves through the Gt Lakes Thu night then lifting to the north and west Friday. Another wave is expected to develop and track south of New Eng with deepening moisture plume moving into the region. Model consensus favors another round of showers on Fri although ECMWF is dry. However, its ensembles support a wetter scenario so we have introduced chc pops, especially along and south of the Pike. Highs will be in the 50s, except upper 40s interior higher terrain. Saturday into Sunday... High pres builds in Sat bringing sunshine and cool temps in the upper 40s and lower 50s. High pres moves offshore Sun but it appears low level dry air will linger into the afternoon so trending drier for much of the day. Overrunning moisture in warm advection pattern may bring a few showers by late in the day. Seasonable temps. Sunday night into Monday... This is likely the period with best chance of showers as fairly robust mid level trough approaches from the west, with warm front approaching Sun night followed by a cold front Mon. Timing is uncertain so we will just have chc pops through this period. Tuesday... Chilly post-frontal airmass as upper trough moves over New Eng. Blustery and cool with temps several degrees below normal. && .AVIATION /06Z WEDNESDAY THROUGH SUNDAY/... Forecaster Confidence Levels... Low - less than 30 percent. Moderate - 30 to 60 percent.
