$$What forecasters said that day
The local office's own words before this coastal flood statement 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 coastal flood statement went out at May 6, 1:45 AM EDT, 2 hours 12 minutes earlier.
Area forecast discussion, May 6, 1:45 AM EDT, 2 hours 12 minutes before
Area Forecast Discussion National Weather Service Boston/Norton MA 145 AM EDT Wed May 6 2020 .SYNOPSIS... High pressure brings dry and near seasonable conditions through Wednesday. A coastal storm tracking southeast of New England will bring a period of rain Wednesday night which may mix with snow at times. Early morning showers Thursday will give way to a drying trend along with seasonably cool temperatures into Friday. Then another storm brings more rain Friday night which may change to snow especially over the higher elevations. Blustery and near record cold follow Saturday with scattered rain and higher elevation snow showers. Then dry weather with moderating temperatures follow Sunday. A cold front may bring scattered showers Sunday night into Monday. Dry and cool weather likely returns Tuesday. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... 145 AM update ... Skies remained clear across all of southern New England as of 145 AM although some high level cloudiness was slowly approaching from the southwest. Temperatures were in the mid 30s to mid 40s across the area with light north to northeast winds. && .SHORT TERM /6 AM THIS MORNING THROUGH 6 PM THURSDAY/... Wednesday should be mostly dry during the day but with increasing cloudcover. At the mid and upper levels a deep trough digs into the Ohio valley as the ridge amplifies over southern New England and begins to shift offshore. Temperatures will cool a bit from today, especially along the east coast where the switch to an onshore, easterly flow will keep temps colder (in the low 50s as opposed to upper 50s inland). At the same time downstream of that trough a sfc low strengthens offshore of the mid Atlantic coast and moves east. High pressure will keep the precip at bay through most of the day, likely moving in in the late afternoon/evening. There remains some uncertainty as to how far north rain will spread, depending on the exact track of the low. For now will mention a chance of rain for all of southern New England between 8 PM Wednesday and 8 AM Thursday, but the axis of heavier precip where we could see a half inch of rain will be over Cape Cod and the islands. Temperature profiles support rain, though some novelty snow flakes may materialize for an hour or two along the souther coast. 850 mb temperature guidance has cooled a few degrees in the last 24 hours down to -2 or -3C, while bufkit soundings show an isothermal layer right around 0C just off the surface. Any chance for snow would be under the heaviest rain (Cape/islands) where the rain itself may allow temperatures to wet-bulb just low enough to support some brief snow. No accumulation would be expected. && .LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/... Highlights... * Thu/Thu night - not a washout but scattered showers & cool * Fri - dry start, possibly a wet finish. Cooler than normal * Arctic blast with potential record breaking cold bringing March- like cold over the weekend with some accumulating snow possible Fri night/early Sat high terrain Details... Thu/Thu night ... upper trough and coastal low may yield morning rain over Cape and Islands followed by short wave ridging to follow for the afternoon. This should promote a drying trend along with some breaks of sunshine. NW flow aloft combined with 850 mb temps of around +1C should support highs in the upper 50s to low 60s, possibly mid 60s if enough sunshine develops in the afternoon. Overall a fairly nice day. Could be a few showers Thu night as next short wave sweeps across the area. Fri ... should be a brief period of dry weather behind departing short wave Thu night and approaching arctic low Friday night. Thus much of Fri could turn out dry especially over RI and eastern MA with showers possibly reaching western MA/CT by days end as arctic front and wave approach. Morning sunshine likely giving way to increasing afternoon clouds. WNW winds becoming SW so cooler south coast. Otherwise highs 55-60. Fri night/Saturday ... Arctic front approaches from the west with wave development along the front. As expected at this time range model differences on amplitude of wave and timing of development. GFS is the quickest with development and farthest southeast with frontal wave tracking over Nantucket early Sat. EC over RI/eastern MA but its ensembles indicate an envelope of solutions ranging from western Georges Bank westward into the Hudson valley of NY...yikes! Given this lack of clustering difficult at this time range to say much more than rain showers possibly changing over to snow showers from west to east with accumulating snow possible WNW of surface low track, provided development is rapid and south of our latitude. Otherwise to little too late with greater risk of accumulating snow across northern New England. During the day Saturday arctic air overspreads the area with 850 mb temps crashing down to about -8C by the end of the day! To put this into context the coldest 850 mb temp on an observed CHH sounding in the month of May is -9C! We will challenge that Sat evening and again Sunday morning with models hovering around -8C/-9C. Cold cyclonic flow will result in lots of diurnal clouds Sat and scattered rain/snow showers, also keeping highs only in the 40s, which may come close to setting a record for daily low max temp. See climate section below. Given this anomalous airmass derived temps from a blend of NBM and the coldest guidance. Gusty WNW winds will yield wind chills in the 30s Saturday! Oh yeah, the normal high should be 62-68...jeez. Sunday ... very cold start with mins Sat night in the upper 20s to lower 30s, mid to upper 30s Cape Cod and Islands including city of Boston. However it will feel even colder Sunday morning with gusty WNW winds continuing. Although not as cold as Sat with 850 mb temps rising from about -9C at 12z to -4C by 00z as polar low over the maritimes continues lifting northeast allowing height rises over southern New England. West winds ease during the afternoon and coupled with at least some sunshine temps rising well into the 50s should feel much better than Sat. Monday/Tuesday ... Next short wave approaches Sun ngt/Mon and associated cold front. Low risk of scattered showers during this time with temps near or slightly cooler than normal Monday. Should be post frontal Tue with dry weather but cooler temps. && .AVIATION /06Z WEDNESDAY THROUGH SUNDAY/... Forecaster Confidence Levels... Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent. 0545ZZ update ... no changes from previous TAFs. Overnight...High confidence. VFR. Light winds. Wednesday...High confidence. VFR with gradually lowering cigs. Chance -RA near the south coast toward evening. E/SE winds 5-10 kt. Wednesday night...Moderate confidence. MVFR/IFR in SHRA along the south and potentially east coast, low end VFR elsewhere. Showers may spread as far north as ORH-BOS. Heaviest showers over Cape Cod and the islands. Showers exit east by mid morning Thursday. KBOS Terminal...High confidence in TAF. KBDL Terminal...High confidence in TAF. Outlook /Thursday Night through Sunday/... Thursday: Mainly VFR, with areas MVFR possible. Breezy. Slight chance SHRA.

Thursday Night through Friday: Winds less than 25 kt. Areas of seas approaching 5 ft. Slight chance of rain showers. Friday Night: Winds less than 25 kt. Areas of seas approaching 5 ft. Rain showers. Saturday: Low risk for gale force winds with gusts up to 40 kt. Areas of rough seas. Chance of rain showers. Saturday Night: Moderate risk for gale force winds with gusts up to 40 kt. Rough seas up to 11 ft. Slight chance of rain showers. Sunday: Moderate risk for Small Craft Advisory winds with gusts up to 30 kt. Rough seas up to 10 ft. && .TIDES/COASTAL FLOODING... High astronomical tides Wed night and Thu night with water levels approaching minor flood. Weak coastal low increases the risk of very minor coastal flooding especially Nantucket midnight tide cycle Wed ngt/early Thu and then again mid night tide cycle Thu ngt/early Fri with perhaps a more elevated risk for south coast given southwest winds. Nonetheless, only very minor coastal flooding expected at this time. Thus no headlines. && .CLIMATE...
