BLWhat forecasters said that day
The local office's own words before this special weather 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 special weather statement went out at Jul 7, 10:05 PM EDT, 1 hour 38 minutes earlier.
Area forecast discussion, Jul 7, 10:05 PM EDT, 1 hour 38 minutes before
Area Forecast Discussion National Weather Service Boston/Norton MA 1005 PM EDT Wed Jul 7 2021 .SYNOPSIS... A front will stall near southern New England Thursday, resulting in cooler weather along with more showers and thunderstorms. Heavy rainfall Thursday night through Friday night will introduce the potential for localized flooding across southern New England as Elsa, or its remnants, moves over southern New England. Unsettled weather through the weekend and early next week with a chance for showers/isolated thunderstorms each afternoon. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... 10 AM update... Short wave trough moving across southeast Quebec is dragging its surface boundary/cool front into northern MA as of 10 pm. This boundary will continue sagging south into CT/RI and southeast MA overnight. Convection along and near this front will dissipate overnight, as best shear tracks across northern New England and higher instability remains south-southwest of New England. Thus diminishing trend in showers/T-storms overnight, with storms no longer a severe threat. Only issue will be some heavy downpours yielding areas of minor street/highway flooding. Given the front will not drive south of New England, despite a wind shift to the N-NE later tonight, not expecting a big airmass change. Therefore, remaining warm and humid overnight with lows in the 60s along with dew pts in the same range. However northern-northeast MA may see dew pts dip into the upper 50s toward daybreak, providing some relief to that region. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/... Nearly stationary front remains draped across the region, with cooler air across northern MA, especially northeast MA with NE winds off the Gulf of ME. As this boundary lifts north, warm sector airmass surges back across the region from south to north. Lots of timing issues remain, with a big bust potential on temperatures near this front. at this time, thinking this front will not make it much farther north than the Mass Pike, so have the highest temperatures south of there. A subtle shift of only 20-50 miles could boost temperatures 5-10 degrees higher in Boston and Worcester. Thinking yet another round of showers for our region, with a lower risk for thunderstorms. Probably will not be able to generate much instability to fuel them. && .LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/... Thursday Night Through Friday Night * Heavy rain Thursday night ahead of Elsa * Elsa moves over southern New England Friday with heavy rain and gusty winds * Unsettled weather through the weekend and early next week. A warm front will lift north through southern New England Thursday night into Friday morning ahead of Elsa. With rich moisture in place to the tune of nearly 2 inches of PWATs there will be the potential for heavy rainfall and flash flooding. Additionally with 30 knots of bulk-shear and close to 1000 J/Kg of MLCAPE, there will be a thunderstorm threat as well. WPC currently has the areas west of I- 495 in as slight risk for excessive rainfall for the Thursday morning through Friday morning time frame. Anywhere from 1-2 inches of rain are expected during that period with locally higher amounts possible. Elsa continues to be the highlight of the extended forecast. Latest guidance takes Elsa over southern New England sometime early Friday morning. Confidence is becoming high that we will see at least some impacts from this system as both deterministic and ensemble guidance are in strong agreement for a closed low passing over southern New England sometime Friday morning. There remains some uncertainty however in whether or not the forecast region will see tropical storm force winds with this system. NHC currently has the southeastern zones in a 10-20 percent probability of tropical storm force winds as the system moves through the area. While ensemble guidance from the ECMWF and GFS are in agreement with the general track of Elsa, there is significant disagreement with respect to the potential for tropical storm force winds (>34 knots). The EC currently has a 30-50 percent probability for winds >34 knots over the South Coast, Cape, and Islands. The GFS on the other hand has less than a 10 percent chance. Thus, the 10-20 percent chance NHC currently has is more than reasonable. Confidence is higher that we'll see substantial precipitation from Elsa. Ensemble means from the GEFS/ECMWF are suggesting widespread areas of 2-3 inches of rainfall in the period from Thursday night through Friday night with locally higher amounts likely. This will again introduce the possibility of flash flooding, especially in urban areas and areas with poor drainage. WPC currently has the southeastern zones minus the Cape and Islands in a slight risk for excessive rainfall for the Friday morning trough Saturday morning period with areas elsewhere at a marginal risk. This may be adjusted in future outlooks. What is important to note is that all of southern New England will have the potential to see some localized flooding between Thursday night and Friday night as tropical downpours are a certainty. Elsa is expected to be clear of the region sometime late Friday. Saturday through Wednesday Seasonable temperatures and unsettled conditions forecast through the weekend and early next week. A persistent Bermuda high continues to pump warm moist air into southern New England from the southwest. Meanwhile an upper-level trough at 500 hPa will be digging into the Midwest early next week. Latest model guidance suggests that embedded short-waves downstream the trough axis will produce the forcing necessary for some isolated to scattered showers each afternoon through Wednesday. There will also be the potential for some diurnal thunderstorm activity as there should at lest be some instability to work with during the afternoon hours. Daily low/high temperatures in the 60s/ upper 70s-lower 80s respectively each day. && .AVIATION /02Z THURSDAY THROUGH MONDAY/... Forecaster Confidence Levels. Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent. 02z update... Thunderstorms will continue to weaken late this evening and overnight. Frontal boundary over northern MA at 02z will continue to sag south overnight into CT/RI and southeast MA, with a wind shift to the N-NE. VFR all terminals at the moment, but IFR/LIFR conditions at KACK may spread inland into southeast MA/RI and the CT River Valley overnight, although confidence is below average. Previous discussion below. =================================================================== Thursday...Moderate confidence. IFR/MVFR in the morning in patchy fog and showers, eventually improves to VFR during the afternoon. Showers in the morning, trending drier in the afternoon but showers and storms could invade the region late in the day. Thursday Night...Moderate Confidence Ceilings come down to MVFR and IFR late tomorrow as heavy rainfall associated with Tropical Storm Elsa begins to overspread southern New England. Heavy rainfall may result in IFR visibilities of 2SM. KBOS TAF...High confidence in TAF. Sea breeze looks to hold just offshore of the terminal until perhaps right before the evening push. Chance of thunderstorms from 22Z-01Z. Strongest storms likely in western and central MA. KBDL TAF...High confidence in TAF. Chance of T-storms through 00Z. A few storms may contain gusts 50+ kt. Outlook /Thursday Night through Monday/... Thursday Night: Mainly MVFR, with areas IFR possible. Breezy. RA, chance TSRA. Friday: Mainly MVFR, with areas IFR possible. Windy with gusts up to 35 kt. RA likely, TSRA likely. Friday Night: Mainly VFR, with areas MVFR possible. Breezy. Chance RA, chance SHRA, chance TSRA. Saturday: Mainly MVFR, with areas VFR possible. Chance SHRA, isolated TSRA. Saturday Night: Mainly VFR, with local MVFR possible. Slight chance SHRA. Sunday: Mainly VFR, with local MVFR possible. Chance SHRA, isolated TSRA. Sunday Night: Mainly VFR, with local MVFR possible. Chance SHRA. Monday: Mainly VFR, with areas MVFR possible. Chance SHRA. && .MARINE... Forecaster Confidence Levels. Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent. Through Tonight... Isolated/Scattered storms early this evening, then moving offshore and giving way to a drying trend. Frontal boundary moves across southern New England and then stalls near the southern waters, with a wind shift to the NE. Poor visibility at times around Nantucket in fog. Thursday... Stationary front draped across the southern waters slowly lifts northward as a warm front. Showers in the morning with isolated thunderstorms, then tapering off in the afternoon before picking back up again in the evening. Outlook /Thursday Night through Monday/... Thursday Night: Winds less than 25 kt. Areas of seas approaching 5 ft. Rain likely, isolated thunderstorms. Friday: Low risk for gale force winds with gusts up to 35 kt. Local rough seas. Rain likely. Local visibility 1 to 3 nm. Friday Night: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Areas of rough seas. Chance of rain, chance of rain showers, isolated thunderstorms. Local visibility 1 to 3 nm. Saturday: Winds less than 25 kt. Areas of seas approaching 5 ft. Chance of rain showers, isolated thunderstorms. Saturday Night: Winds less than 25 kt. Seas locally approaching 5 ft. Slight chance of rain showers. Sunday: Winds less than 25 kt.
