What forecasters said that day
The local office's own words before this flood watch 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 flood watch went out at Jan 10, 1:32 PM EST, 1 hour 45 minutes earlier.
Area forecast discussion, Jan 10, 1:32 PM EST, 1 hour 45 minutes before
Area Forecast Discussion National Weather Service Taunton MA 132 PM EST Wed Jan 10 2018 .SYNOPSIS... High pressure moves east of the region today and tonight bringing milder weather on Thursday. Unseasonably mild temperatures are anticipated Friday into Friday night along with periods of heavy rain, gusty winds along with the potential for some flooding. The rain may end as some ice across the interior on Saturday if the much colder air arrives before the precipitation ends. Dry and very cold weather is favored Sunday into Monday. && .NEAR TERM /THROUGH TONIGHT/... Large high pressure will continue to move east of our region today. Light and variable winds will eventually become light south winds by late today. Only minor tweaks to the forecast early this afternoon to reflect observed trends. Strong warm air advection in the lower level begins in earnest tonight. Increasing clouds mid and high level clouds, especially across the western two-thirds of southern New England. With 925 mb winds expected to increase to 35-45 kt toward midnight, expecting minimum temperatures to be rather early tonight, then remain nearly steady or slowly rise after midnight. Minimum temperatures currently forecast to be about 10 degrees above normal. The other issue with the strong warm air advection will be the possibility for some overrunning precipitation this evening and overnight. There is a window this evening towards NW MA for period of spotty freezing drizzle. The majority of the forcing and deeper moisture appear to be just to the NW of our area. Thinking coverage is not going to be widespread enough to issue a Winter Weather Advisory at this time. && .SHORT TERM /THURSDAY THROUGH THURSDAY NIGHT/... Very mild weather by mid January standards expected Thursday and Thursday night, with readings at least 15 degrees above normal through this period. Expecting continual snowmelt during this time, which will begin to set the stage for a flooding threat later this week. Areas of fog also expected, some of which may be fairly dense, especially Thursday night. Expecting mainly dry weather Thursday, with an increasing risk for rain from west to east Thursday night, especially from Worcester county and RI, west. && .LONG TERM /FRIDAY THROUGH TUESDAY/... Highlights... * Heavy rain yields a flooding risk Fri and Sat. * Rapid freezing possible late Sat. * A return of colder than normal conditions early next week. Overview and model preferences... A gradual transition in a slight positive NAO/AO regime as subtropical high begins to form block in the W Atlantic, allowing the trof over SoCal phases with a weaker N stream wave, leading to a draw of tropical moisture and high latent heat through a mean SW-NE oriented jet. Two waves will traverse the attendant sfc front Fri and Sat which looks to lead to periods of heavy rainfall. Thereafter, as the ridge continues to form a block offshore, the longwave will phase with arctic wave and allow another round of arctic air to follow the wet/unsettled period. 10.00Z model guidance suite continues to show generally good synoptic scale agreement through the weekend. While there continues to be meso-scale and thermal profile disagreements, these will slowly become resolved now that the initiating wave (the cutoff currently impacting SoCal) is onshore and being better sampled. Given the agreement at this level, will continue to lean most heavily on ensembles. This is mainly due to the anomalous tropical moisture event expected during this period, and the low risk for the influence of low lvl cold air on Sat (something that at least a few members reflect). Details... Fri... Deepening longwave reaches the Gulf of Mexico, allowing the advection of high PWAT air (nearly 1.5 inches, which is almost 5 std deviations above January normals) toward New England. While the first in a series of frontal waves moving along a slow moving baroclinic zone to the NW is expected to shift through the Great Lakes into Quebec, a 60+ kt LLJ with strong front end convergence will yield a period of mod-heavy rain early Fri morning into the daytime on Fri. This will be the shorter lived and generally weaker of the two waves, but still, QPF values could approach 1.00-1.50 until dry air filters in aloft, leading to diminishing rainfall rates through the late afternoon and evening. This is in advance of stronger latent heat release upstream near the S tail of the Appalachians which will form a stronger frontal wave moving through on Sat. More on this below, along with the potential impacts of heavy rain both Fri and Sat. Temps remain mild thanks to H92 temps near +10C, yielding highs in the low-mid 50s. Fri night into Sat night... Secondary frontal wave, this one associated with a nearly 70+ LLJ (even as low as H92) will pass along the front as it moves across S New England. The timing is critical here, as this low could ultimately pass directly over, to the W or to the E of New England. Ensembles still yield a lot of spread at this time, but this will need to be watched. A W or direct track would allow for heavier rain with convective elements as K-values shift well above 30 and conditionally unstable soundings yield modest MU CAPE. These tracks could also be the means by which some of the momentum from this strong LLJ is able to mix to the sfc, however with some lingering snowpack and an implied inversion on soundings, a lack of near sfc mixing may be able to keep it aloft. Still something to watch. Otherwise, a further E track could allow for shallow, near sfc cold air in fast enough (thanks to isallobaric north and northwesterlies) before the main precip shield dissipates, allowing for some wintry mix (most likely FZRA) across the interior. As mentioned above, these are mesoscale features which will gradually evolve. In any case, another round of heavy rain is likely with convective the help. The heavy rain, will combine with high dwpts to yield snowmelt beginning Fri and continuing on Sat. With full QPF from both waves yielding a potential between 1.50-4.00 inches (even more in specific runs), the additional snowmelt, combined with a potential for snow clogged drains could yield some urban and poor drainage flooding, as well as some flooding specifically in flashier small streams. Following the flooding risk, the influence of cold air timing will be important, as a freeze is possible immediately following heavy rain. Overnight mins are likely to dip below freezing before Sun morning. Sun... As low pres shifts into the Maritimes, colder air begins to filter in from the W, although arctic high pres remains across the Great Lakes. Temps aloft, nearly isothermal through H85, hover between -10C and -12C. This is near the standard for mid January, so expect highs Sun to remain near seasonal normals, but colder than previous 48 hours. Sun night mins however will be dependent on center of high pres, but there is a possibility for radiational cooling, with lows in the single digits or low teens. Early next week... Arctic influenced airmass remains in place with high pres especially through Tue. However, will need to watch waves rotating through the longwave trof, which could bring about a snowfall event. Confidence is low in timing or details at this time. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... Forecaster Confidence Levels... Low - less than 30 percent. Moderate - 30 to 60 percent.
