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 22, 4:28 PM EDT, 2 minutes earlier.
Area forecast discussion, Aug 22, 4:28 PM EDT, 2 minutes before
Area Forecast Discussion National Weather Service Boston/Norton MA 428 PM EDT Sat Aug 22 2020 .SYNOPSIS... Warm and humid conditions continue Sunday and into early next week. Mainly diurnally driven thunderstorms are expected thru Tuesday, though the majority of the time will be dry. Somewhat cooler and less humid weather arrives by Wednesday, but this may end up short- lived. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... 415 PM Update... Short wave trough moving across northern New England into southeast Quebec providing sufficient synoptic scale lift combined with 500- 1000 ML CAPE to support scattered thunderstorms with locally strong to damaging winds, large hail and very heavy rainfall with PWATs up to 1.5 inches. Best low level convergence is across CT/RI and south of the MA Pike especially southeast MA with seabreeze boundaries. Thus this will be the area of focus for convection the next several hours. As sunset approaches and instability wanes along with mean trough axis moving offshore and subtle height rises occurring over SNE, convection will dissipate and give way to quiet late evening weather. No frontal passage or airmass change tonight, so a warm and humid night with lows in the 60s, possibly a few upper 50s in northwest MA and the I495 corridor of MA such as OWD. Dew pts in the 60s combined with rainfall from today's storms and light winds/clearing skies will likely result in patchy fog overnight. Also watching area of stratus/fog across western Gulf of ME. This low level moisture is advecting westward and may impact eastern MA especially Cape Cod overnight. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/... 430 PM update... Sunday... Warm and humid airmass remains over the region with 850 mb temps around +16C and model soundings indicate mixing to about 800 mb. This should support another round of high temps from the upper 80s to low 90s away from the coastal seabreezes. It's likely KBDL ties its summer record of 38 days of 90+ heat set back in 1983! We are forecasting a high of 92. It will feel very summer-ish with dew pts in the 60s to near 70 along the south coast. These dew pts and warm temps will yield heat indices tomorrow in the mid 90s! Not worthy of an advisory but nonetheless hot conditions tomorrow. Any morning low clouds/fog will quickly burn off and give way to lots of sunshine. Weak pressure gradient tomorrow offers very little wind but will promote cooling seabreezes near shore. Just like today, these seabreezes may provide a focus tomorrow for convection especially northeast MA. As for convection, modest short wave/mid level speed max moves across northern New England. This may be sufficient to fire off storms especially across northern MA. Severe parameters somewhat out of phase with greatest instability over CT/RI and southeast MA with MU CAPEs up to 2000 j/kg. However strongest forcing for ascent farther north. HREF focusing northeast MA for potential big storms. Wind fields aloft are weak but may be sufficient CAPE to compensate so strong winds, hail and heavy rain (PWATs up to 1.8 inches) are the main concerns. Sunday night... Any early evening showers/T-storms will dissipate with sunset giving way to quiet but warm and humid weather overnight with dew pts 65- 70. Light SW winds. && .LONG TERM /MONDAY THROUGH SATURDAY/... Highlights * Showers and thunderstorms Monday and into Tuesday. Muggy and warm conditions as highs reach near 90 degrees on both days. * Comfortable and dry mid-week. Becoming cooler than normal and unsettled late weekend into next weekend. Monday afternoon through Tuesday night... Warm and muggy conditions return to southern New England for the start of the week. 850 mb temperatures are forecasted to reach +16C to +19C ... which is between +4C to +5C above normal for late August. Given the anomalous 850 mb temperatures both days, surface high temperatures could make a run for the middle and upper 80; a few location might reach 90 degrees. Additionally, dewpoints will also make a resurgence into the upper 60s to lower 70s. The climatological average for late August are dewpoints in the low 60s for a reference point. Above normal dewpoints combined with warm surface temperatures could make it feel like the mid-90s. Southern New England will lay between a ridge of high pressure to our south and a low pressure trough to the north. Monday afternoon sct'd thunderstorms are likely, surface based CAPE is forecasted between 1,300 J/kg and 1,900 J/kg and modest mid-level lapse rates above +7C/km. Mid-level lapse rates on Tuesday mimic Monday, but, surface based CAPE is forecasted between 800 J/kg and 1,300 J/kg. Additionally, heavy downpours would be likely on Monday as PWAT values range between 1.50" and 2.00". Wednesday through Saturday... A break from the heat and humidity for mid-week with temperatures on either side of 80 degrees and wicked sweet dewpoints in the upper-40s inland and close to lower-60s at the coast. Wednesday appears to be the driest day out of next week as high pressure shifts east. Chances for showers and storms returns on Thursday and Friday. At this point it doesn't appear to be a washout. Temperatures late into next week will remain in the upper-70s to low-80s and dewpoints in the low-60s. Next weekend there remains uncertainty as tropical remnants move off the mid-Atlantic coast. Additionally, the models are also hinting at come cooler conditions with afternoon highs struggling to reach the lower 70s for the final weekend of August. && .AVIATION /21Z SATURDAY THROUGH THURSDAY/... Forecaster Confidence Levels... Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent. 18z update... Thru 00z...high confidence. Scattered T-storms with marginal MVFR/VFR. A few strong storms with wind gusts to 50 kt, large hail and frequent lightning. Otherwise VFR with light WSW winds except local seabreezes. After 00z...High confidence in the evening but low confidence overnight in low cloud potential. Any showers/storms coming to an end. VFR initially, but low risk of MVFR to IFR stratus advecting into eastern MA/RI terminals. LIFR conditions cannot be ruled out at Cape Cod and the Islands. Light S/SW winds. Sunday...High confidence. Any stratus/fog to burn off early to VFR conditions. Iso to Sct afternoon TSRA possible but mixed signals on storm coverage. Storms may be more numerous over northern portions of MA/CT/RI. Regardless less coverage than today and not and intensity less. SW winds 5-10 kt, locally stronger/breezy near the Cape where models show a low-level jet that could produce afternoon gusts in the low 20s kt range. Sunday night...high confidence. Any evening storms diminish shortly after sunset. Otherwise VFR with local MVFR/IFR in patchy fog overnight. Light winds. KBOS Terminal...High confidence in TAF. Scattered storms will threaten the airspace of KBOS thru about 00z with strong winds, large hail and frequent lightning. Improving conditions after 00z. Low clouds over the Gulf of Maine may threaten the airport overnight but more likely impact Cape Cod. KBDL Terminal...High confidence in TAF. Outlook /Monday through Thursday/... Monday: VFR. Chance SHRA, chance TSRA. Monday Night: VFR. Slight chance SHRA. Tuesday: VFR. Breezy. Chance SHRA, chance TSRA. Tuesday Night through Wednesday: VFR. Breezy. Wednesday Night: VFR. Slight chance SHRA. Thursday: VFR. Chance SHRA. && .MARINE... Tonight...light winds with evening storms over the southern MA and RI waters dissipating with sunset. Patchy fog overnight limiting vsby. More widespread fog possible eastern MA waters as stratus/fog currently over western Gulf of Maine advects westward toward MA. Sunday...light winds. Any morning fog burns off by midday. Another round of storms likely but this time probably focused across the northern MA waters. Sunday night...evening storms dissipate with sunset. Patchy fog likely. SW Light winds. Outlook /Monday through Thursday/... Monday: Winds less than 25 kt. Slight chance of rain showers, slight chance of thunderstorms, patchy fog. Monday Night: Winds less than 25 kt.
