BLWhat forecasters said that day
The local office's own words before this areal flood 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 areal flood warning went out at Jul 17, 6:41 PM EDT, 1 hour 8 minutes earlier.
Area forecast discussion, Jul 17, 6:41 PM EDT, 1 hour 8 minutes before
Area Forecast Discussion National Weather Service Boston/Norton MA 641 PM EDT Sat Jul 17 2021 .SYNOPSIS... A front will remain over southern New England this weekend and will be the focus for showers and thunderstorms. Our weather will remain unsettled into next week, with temperatures averaging near normal and scattered showers and thunderstorms at times. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... 640 PM update... Frontal boundary has sagged south from recent convection and is aligned from just south of HFD-PVD-PYM. Still low/mid 70s dewpoints along and south of the boundary. The front is expected to stall near the south coast. Most of the showers and t-storms have shifted along and north of the boundary across interior MA into northern CT. MLCAPES still 1000-1500 J/kg but diminishing as environment is pretty worked over so weakening trend will continue this evening. However, additional showers/t-storms are expected to move across the region from the west tonight ahead of the mid level trough. Heavy rainfall threat will continue, with the focus in central/W MA into N CT. Previous discussion... * Potential for flash flooding across much of CT and western/central MA Areal coverage of showers and t-storms are increasing along a frontal boundary draped across northern CT/RI and SE MA. MLCAPES 1000-2000 J/kg along and south of the Pike providing ample instability for low level convergence to act on. Effective shear around 30 kt which is sufficient for some organization and a few stronger to severe storms. Focus for severe storms through the afternoon will be along and south of the Mass Pike within the instability axis. The stronger cores are capable of damaging wind and large hail. Also a low risk for an isold tornado along the warm front which provides a source of surface vorticity and low level shear. Heavy rainfall will also be a risk through this evening with near 2 inch PWATs and deep warm cloud depths and long skinny CAPES. While SB instability diminishes tonight, marginal elevated instability will persist. Additional convection is developing in western MA and CAMs indicate increasing coverage of showers and storms in western New Eng well into this evening and past midnight as slow moving mid level trough moves east from the Gt Lakes with a modest uptick in a low level jet. Rainfall amounts of 1-3 inches are expected in the flash flood watch area of central/W MA into northern CT with CAMs indicating potential for localized 4-5" amounts. Localized flash flooding will remain a threat. Weakening convection with sct showers and isolated t-storms is expected overnight across eastern New Eng. Meanwhile, areas of dense fog expected to redevelop over the Islands and expand across portions of the immediate south coast and Cape/Islands tonight. Lows will range from mid 60s in northern MA to lower 70s near the south coast which will remain south of the boundary. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/... Another round of scattered showers and t-storms expected Sun as mid level trough approaches from the west. Expect more cloud cover Sun which will result in less instability but still expecting MLCAPES 1000-1500 J/kg. Surface front will remain across SNE, likely near or a bit south of the Pike. CAMs suggest greatest coverage of showers and storms will be north of the boundary where convection may be elevated. PWATs are still rather high, up to 2 inches, so heavy rainfall will continue to be a threat. Better instability to the south so if any storms can develop in CT/RI and SE MA, a few strong storms would be possible. Deep layer shear is marginal (around 25 kt) so not looking a widespread or significant event. Warmest temps into the lower 80s will be south of the front across CT/RI and SE MA where oppressive humidity will continue with dewpoints in the lower 70s. Temps cool into the 70s to the north and may fall into the upper 60s across portions of northern MA. && .LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/... Highlights... * Pattern looks unsettled till middle of next week. * Potential for drier pattern by later in the work week. * No big heat in the horizon. The NBM guidance looks reasonable so no significant changes to the extended forecast. Widespread showers and thunderstorms look likely on Monday as a surface low associated with a slow-moving cold front is forecast to be in our vicinity. For Tuesday, thunderstorm coverage becomes more scattered and more confined to the interior before increasing again on Wednesday as we await the arrival of a stronger cold front which will serve as a 'kicker'. So for the first half of the work week, expect continued unsettled weather pattern with muggy conditions and even oppressive humidity. For those of you tired of the unsettled pattern, there are indications that we see a drier and cooler (slightly below normal to near normal temps) towards the latter half of the work week. An upper level trough will become increasingly anchored over our area. Although this means that there could be diurnal showers and isolated thunderstorms with a cold pool aloft, it seems that surface high pressure will also be taking hold. In fact, both the CPC 6-10 and 8- 14 day outlook advertise good confidence of below normal temperatures and below normal precipitation for Southern New England. Height fields and temperature aloft (850mb and above) are around 1 standard deviation below normal according to NAEFS Situational Awareness Table. Both the GFS and EC show -15 to -16C H5 cold pool (10th percentile according to ALY SPC sounding climatology) moving overhead, although there is some difference in timing. While day-to-day synoptic and mesoscale details remain to be ironed out (think northeasterly flow for areas along the Eastern MA coast), the odds are we may get a taste of early fall towards later next week, along with lower dew points to boot. && .AVIATION /22Z SATURDAY THROUGH THURSDAY/... Forecaster Confidence Levels. Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent. Through tonight...Moderate confidence. MVFR/VFR this evening in showers and sct t-storms, greatest coverage interior MA and CT. Stratus and fog over the islands will expand northward across SNE through tonight with conditions lowering to IFR/LIFR. Sunday...Moderate confidence. IFR/LIFR in the morning improving to MVFR with areas of VFR in the afternoon. Scattered showers and t-storms. KBOS TAF...Moderate confidence in TAF. KBDL TAF...Moderate confidence in TAF.

Moderate - 30 to 60 percent. High - greater than 60 percent. High confidence through Sunday. Stalled front over region will result in light winds and seas through tonight. SW winds increase to 10-15 kt over the southern waters with seas remaining below SCA thresholds. Areas of dense fog will mainly impact south coastal waters tonight into Sun morning. Scattered showers and thunderstorms tonight and Sunday. /Outlook /Sunday Night through Thursday/... Sunday Night: Winds less than 25 kt. Areas of seas approaching 5 ft.
