BLWhat forecasters said that day
The local office's own words before this river 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 river flood warning went out at Jul 10, 9:44 AM EDT, 3 hours 8 minutes earlier.
Area forecast discussion, Jul 10, 9:44 AM EDT, 3 hours 8 minutes before
Area Forecast Discussion National Weather Service Boston/Norton MA 944 AM EDT Mon Jul 10 2023 .SYNOPSIS... Widespread showers and scattered thunderstorms with heavy rainfall will move across the region today. The highest risk for significant flooding will be across far western New England. Showers will be lifting to the north tonight. Drier weather Tuesday, then hot and humid conditions return Wednesday. The dry weather pattern is brief, with rain chances increasing through the end of the workweek. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... 940 am update... going forecast in pretty good shape. Made minor tweaks to the hourly PoP progression based on current radar trends. Folded in the HREF and Hi-ResARW which seemed to be the two models doing the "better" job compared to current precipitation coverage. Concern the next few hours revolves around the batch of moderate to heavy rain that is moving into eastern CT as I type. Saw a CoCoRaHS report out of New London county CT of over 4" in 90 minutes a little bit ago. Goes to show how efficient the rainfall is even if the reflectivities aren't super high. Very tropical/warm rain processes going on. This batch of rain should continue to push NNE, so concerns for flooding will move along with that. Particularly for the urban areas around PVD. Could also be problems in Fall River as well as that area has problems with just 1" of rain in a short time. We are closely monitoring radar trends and MRMS/FLASH outputs to help with flooding potential. Currently some breaks in the clouds across CT, but given the very tropical atmosphere (precipitable water values ranging from 1.9" to 2.1"), the little extra instability will lead to more showers developing. Instability parameters not overly high, but marginal enough that a few t-storms are possible especially across CT, RI and into SE MA for the afternoon. 630 AM Update Forecast remains on track. KBOX radar beginning to reveal moderate to heavy rainfall across western MA and CT this morning. Expect moderate to heavy rainfall to continue into the afternoon. Radar reflectivity over Rhode Island is more of the light to moderate category at this hour, but more intense rainfall rates are forecast to develop over this area over the next couple of hours. No flash flood warnings have been issued at this time, but special weather statements are in effect for most of Hartford county and the areas west of I-91 to the east slopes of The Berkshires. We'll continue to monitor trends and may issue flash flood warnings where appropriate. No changes have been made to the forecast for today, see further details in the previous discussion. Previous Discussion Highlights... * Highest risk for flash flooding through the morning will be from the Berkshires to western CT * Secondary maximum of heavy rainfall possible across RI * Low risk for a few strong/severe storms Quite an anomalous system for mid July with amplifying mid level trough moving east from the Gt Lakes and closing off as it lifts into central/northern New Eng tonight. Strong forcing for ascent acting on tropical moisture plume will bring heavy rainfall to portions of SNE today. Hi-res and global guidance is in excellent agreement that the most prolific rainfall from this storm will be across VT. However, will see heavy rainfall amounts extending south across western New Eng. Surface low off the mid Atlc coast with an inverted trough extending to the north into SE NY. It appears this boundary will be a focus for heavy rainfall through the morning as it moves slowly E into western CT/MA. This is where the greatest risk for possible flash flooding will be this morning, especially from the Berkshires to western CT, mainly west of I-91 as heavy showers and embedded t- storms blossom and move north across this area. HREF indicating moderate probs of greater than 1"/hr rainfall rates in this region. Numerous showers and embedded t-storms will be moving east across rest of SNE today as shortwave energy rotates around the base of the trough and approaches from the SW and sfc low and boundary move eastward. Multiple CAMs are suggesting a secondary heavy rainfall max across RI today, which could produce street flooding and bring about rapid rises of creeks and streams and fast responding rivers. Locally heavy rainfall also expected in portions of eastern MA but not expecting significant impacts in this area. Regarding rainfall amounts, we expect the heaviest rain with potential for storm total amounts of 2-4 inches and locally higher amounts across the Berkshires to far western CT. Elsewhere, generally 1 to 2 inches expected with less across SE MA and especially Cape Cod, but locally 2+ inches possible across portions of RI. The other concern for today is the potential for a few strong to severe t-storms. 0-6km shear is increasing to 30-35 kt but instability may be a limiting factor. CAPES of 500-1000 J/kg are expected, possibly a bit higher in western New Eng. If the higher instability can be realized the potential exists for a few strong to severe storms with wind the main concern. However, always have to be watchful for spinups in tropical environments with increasing shear, especially near boundaries. Low level wind field is weak and helicity values are unimpressive, but 0-3km CAPE is decent and we have a boundary which could locally enhance low level shear. CSU machine learning probs are highlighting a very low TOR risk so will have to closely monitor radar for rotation. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 AM TUESDAY/... Tonight... Dry slot will be overspreading SNE from the south tonight leading to showers tapering off from south to north this evening. Mid level low lifts across central/northern New Eng and southern edge of the comma head could keep showers going into the overnight across northern and especially NW MA. Lows will be mostly in the 60s. && .LONG TERM /TUESDAY THROUGH SUNDAY/... Highlights... * Mainly and very warm Tue * Hot and sunny on Wednesday with somewhat drier conditions * Unsettled weather and humidity returns on Thursday Wednesday A brief period of dry weather for southern New England on Wednesday as a relatively dry air mass characterized by PWATs ranging from 1 to 1.25 inches which is relatively low for mid-July. This will support abundant sunshine across southern New England on Wednesday with the exception of some diurnal cu. 925 hPa temps near 25 Celsius will support hot temperatures in the low 90s at the surface. With dewpoints only in the mid to upper 60s, the heat index will only be a degree or two higher on Wednesday afternoon. Wednesday definitely looks to be the pick of the week for those who prefer sunshine. Thursday and Friday The dry spell is very short-lived as a moisture and humidity return to southern New England on Thursday. Deep southwest flow will advect of a plume of 1.75+ inch PWATs over the region. This will result in increasing cloud cover Thursday morning into Thursday afternoon. As an upper-level disturbance approaches from the west we may see some showers and thunderstorms by the mid-afternoon across the western areas before spreading east Thursday night into Friday. As short- wave energy associated with this disturbance lifts northeast over The Hudson River Valley Thursday night through Friday, southern New England is likely to receive another round of substantial rainfall. Won't dive into the where and how much just yet, but given soils are likely to be saturated from tonight and tomorrows heavy rainfall threat, we'll have to be on the lookout for flood/flash flood potential as we approach the end of the week. Given favorable antecedent conditions, WPC has placed portions of western MA and CT in a marginal risk for excessive rainfall for the Thursday/Friday time frame and a slight risk for the Friday/Saturday time frame. Next Weekend Broad cyclonic flow aloft with embedded short-waves will continue to support shower/thunderstorm chances over The Northeast next weekend. Details are vague at this time, so have leaned on NBM for guidance which appropriately places chance PoPs across the region. && .AVIATION /14Z MONDAY THROUGH FRIDAY/...

Thursday Night through Friday: Winds less than 25 kt. Seas locally approaching 5 ft. Scattered rain showers, isolated thunderstorms. && .HYDROLOGY... Rivers: For the latest river stage levels and forecasts, see the forecasts from the Northeast River Forecast. Larger rivers and smaller streams are expected to rise through today in the face of heavy rains. NERFC forecasts call for rises into the Minor Flood Category on most of the Connecticut River basins later Monday into Tuesday. We are most concerned about the Connecticut, Deerfield, Westfield, and Farmington Rivers to experience rises to near or over bankfull. Besides just local rainfall amounts reaching the rivers, rains falling upriver in the CT River basin in VT and NH will likely lead to additional rises even after heavy rains have ended. && .BOX WATCHES/WARNINGS/ADVISORIES...
