FrankWhat forecasters said that day
The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at Aug 23, 4:21 PM EDT, 51 minutes earlier.
Area forecast discussion, Aug 23, 4:21 PM EDT, 51 minutes before
Area Forecast Discussion National Weather Service Boston/Norton MA 421 PM EDT Sun Aug 23 2020 .SYNOPSIS... Warm and humid conditions will continue into Tuesday, when a strong cold front will move across the region. Isolated severe thunderstorms are possible Monday afternoon and evening but more widespread severe storms are possible Tuesday. After a brief taste of fall on Wednesday, summer weather and thunderstorms return by late week into the weekend. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... 410 PM update... Scattered strong to severe thunderstorms were occurring in northern MA, mainly north of the Mass Pike. Numerous trees were downed in the Orange, MA area. Downdraft CAPE and mid level lapse rates near 6 C/km were helping some storms to be severe. Additional storms were approaching the Berkshires from eastern NY. Any leftover storms should weakening and/or move offshore early tonight. We should see improving conditions as we move into the midnight/early-overnight hours. However, the higher dewpoints and light southwest flow should allow a renewed generation of fog and low clouds in southern RI and southeast MA, including Cape Cod and the Islands. Locally dense fog is likely. Muggy overnight with lows in the mid 60s to near 70. && .SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/... Monday... Looks like pretty much a repeat of what we have had on Saturday and Sunday. Fog and low clouds in southeast areas will dissipate around mid-morning. A weak surface pressure gradient will be in place with relatively light flow aloft. Strong heating will take place, with highs again near 90 in the interior (cooler at the immediate coast) and dewpoints in the upper 60s to lower 70s. Model K Indices reach 35 to 38, which spells more convective activity in the afternoon and evening hours. No particular focusing mechanisms, but bulk shear values will be better in the central and southeastern part of the region. Sea breeze fronts may also play a role. A few severe storms cannot be ruled out. Monday night... Evening showers or thunderstorms will dissipate. A strong cold front advancing through the Great Lakes will remain well to our west. We can expect another muggy night with lows in the upper 60s to near 70. Areas of fog possible again, mainly in southeast sections, although increasing winds aloft may make it less widespread than Sunday night and just confined to the immediate south coast. && .LONG TERM /TUESDAY THROUGH SUNDAY/... Highlights * Strong to severe thunderstorms are possible as a cold front moves across New England. * A brief taste of fall for mid-week as temperatures drop into the low and middle 70s. * Unsettled weather pattern second half of the week and chance for remnant tropical moisture by next weekend. Through Tuesday Evening... As previously stated in a prior discussion, the NAM continues to show a fast bias for the arrival of the cold front - with the front arriving between 12z and 18z. While the ECMWF/GFS/CMC show good agreement the arrival of the cold front between 18z Tuesday and 00z Wednesday. The Storm Prediction Center has placed all of southern New England under a 'Slight Risk' for severe weather Tuesday. SB CAPE values are modest, between 1,000 and 2,000 J/kg and show sufficient deep layer shear between 35 and 50 knots. Still on track, an EML moving in from the mid section of the country, forecast lapse rates for mid-levels are between +6C/km and +7C/km and low-level lapse rates reach +7C/km and +8.5C/km. That coupled with daytime maximum temperatures in the upper 80s to near 90 degrees, dewpoints between 68F and 70F, the parameters are looking healthy to support strong and severe storms. Heavy downpours are also likely, PWAT values are between 1.50" and 1.80" during the afternoon. Urban flooding would be the biggest concern as area waterways remain lower than normal as a result of the dry weather pattern. Wednesday... ***Small Craft Advisory might be needed as outer water could see wave heights between 5 & 7 feet*** High pressure slides south out of Hudson Bay in Canada and with a northwest flow it will feel as if it were early fall. I did go with a bit of cooler guidance, maximum temperatures will be found away from the coast and higher terrain of the Berkshires in the mid-70s. At the coast temperatures will be in the low-70s and even the upper 60s in the Berkshires. Additionally, dewpoints will be in the mid- 40s inland and mid-50s at the coast. Those who've been waiting for a refreshing "fall-like" day... Wednesday is it! Thursday through Friday... The end of the week is looking like unsettled weather. Thursday the chance for rain returns, but the ECMWF and GFS vary on how fast a weak area of low pressure moves; the GFS being the slower of the two. Friday, the ECMWF lingers a few showers during the day while the GFS dries us out. It will also be noticeably warmer, with temperatures trending back into the upper 70s to 80 degrees on Thursday and the low 80s Friday and Saturday with dewpoints in the low and middle 60s. Saturday... While it is still far off, the models are showing signs of remnant tropical moisture from Marco & Laura could get caught in the upper- level flow and arrive into southern New England by as early as Friday night or Saturday. With this still being several days away I will not get into any specifics. Temperature wise, the second half of the weekend trends a bit cooler, falling back into the low and middle 70s. && .AVIATION /20Z SUNDAY THROUGH FRIDAY/... Forecaster Confidence Levels... Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent. 2010Z update... Into this evening...High confidence. VFR except brief IFR in scattered thunderstorms through 02Z. Greatest coverage mainly along/N of a KBDL-KPYM line. More isolated TSRA threat southward from PVD to Cape Cod. A few TSRA may become severe with wind gusts to 50 kt and hail. Winds mainly SW 10-15 kt, locally stronger at the Cape airports where stronger low-level jet could support occasional 20 kt gusts. Sea breezes and onshore flow along the coast. Tonight...High confidence. Any thunderstorms diminish this evening. Will likely have brief VFR conditions, but expecting IFR to LIFR fog and stratus tonight in portions of RI and southeast MA, especially along the south coast. Any areas where a shower/storm moved through this afternoon will have a better opportunity for fog developing. Light SW winds. Monday: High confidence. Early-day IFR-LIFR fog and/or stratus burning off soon after sunrise. Mainly VFR, but strong heating will again lead to a risk for SHRA/TSRA. Light SW winds with sea breezes at the coast. KBOS Terminal...High confidence in TAF. Sea-breeze around 14-15z, potential time window for VCTS/TSRA approx 20-01z. KBDL Terminal...High confidence in TAF. Potential time window for VCTS/TSRA approx 18-22z. Outlook /Tuesday through Friday/... Tuesday: VFR. Breezy. Chance SHRA, chance TSRA. Tuesday Night through Wednesday: VFR. Wednesday Night: VFR. Slight chance SHRA. Thursday: Mainly VFR, with local MVFR possible. Chance SHRA. Thursday Night: Mainly VFR, with areas MVFR possible. Chance SHRA, chance TSRA, patchy BR. Friday: Mainly VFR, with local MVFR possible. Chance SHRA. && .MARINE... 410 PM update... Most waters should remain below SCA levels through Monday night. Scattered thunderstorms could produce strong wind gusts during the afternoon and evening hours. Areas of dense fog, with local visibilities below one-quarter mile, mainly tonight and Monday night, over the southeastern waters. Outlook /Tuesday through Friday/... Tuesday: Winds less than 25 kt. Seas locally approaching 5 ft. Chance of rain showers, chance of thunderstorms. Tuesday Night: Winds less than 25 kt. Areas of seas approaching 5 ft. Slight chance of rain showers. Wednesday through Wednesday Night: Winds less than 25 kt. Seas locally approaching 5 ft. Thursday: Winds less than 25 kt. Seas locally approaching 5 ft. Chance of rain showers. Thursday Night: Winds less than 25 kt. Seas locally approaching 5 ft. Chance of rain showers, chance of thunderstorms, patchy fog. Friday: Winds less than 25 kt.
