(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kbox 161820 afdbox area forecast discussion national weather service boston norton ma 120 pm est Fri nov 16 2018 Synopsis Dry and chilly weather continues into Sunday morning. Weak low pressure may bring patchy light rain and or snow late Sunday into Monday. Another shot of colder air moves in by the middle of next week, though it should be mainly dry. Near term until 6 pm this evening 120 pm update... a cold and blustery day with considerable cloudiness was the main story early this afternoon behind the departing low pressure system. A few left over light rain snow showers across central and northeast ma will come to an end shortly. It was still breezy in many locations and rather windy across the cape islands with cold NW low level flow mixing quite well over the milder sst. Temperatures will generally be in the 30s for the remainder of the afternoon. Short term 6 pm this evening through Saturday night A broad upper trough lingers over hudson bay through Saturday night. Several shortwaves move through this flow and over southern new england. 500-mb heights remain near to below normal through the period. Normal values are 557 to 563 decameters, while forecast values are in the 540s today and 550-555 Saturday. One shortwave moves across southern new england early tonight. This may be enough to generate scattered snow showers, especially across northern massachusetts. These snow showers should move out of state before midnight. Cold advection will maintain some level of mixing tonight and Saturday. Low level winds will be 30-35 kts tonight and 20-25 kts Saturday. Expect most or all of this wind to mix to the surface in gusts tonight and Saturday. Moisture cross sections show diminishing moisture aloft on Saturday. This suggests a dry day, allowing for sunshine. Temperatures upstream are in the upper 20s and lower 30s... This should suffice for tonight's min temps. Mixing on Saturday should reach 925 mb, where temps will support MAX surface temps in the 40s. Min temps farther upstream point to Saturday night mins in the mid 20s to lower 30s. Long term Sunday through Thursday Highlights... * no changes to Thursday afternoon long term forecast for this period. * below average temperatures persist * weak low pressure brings periods of rain and snow late Sun into mon * dry and cold mid week overview... the extended forecast features a few high pressure systems sandwiched around a relatively weak low pressure disturbance or two in the Sunday night Monday time frame which will bring the return of both rain and snow chances. Model consensus is good that the flow pattern becomes much less amplified and more zonal behind Friday's system, persisting through late weekend. By then a mid level shortwave digs south, crossing the region Sunday Monday which will generate a weak surface low in the vicinity of sne with another round of light snow rain. Beyond this, models diverge a bit, with the GFS keeping things unsettled into Tuesday before the high returns, while the euro returns a dry high pressure more quickly. Either way, by mid to late week heights begin to rise ever so slightly and a cold and dry pattern returns. Details... Sunday and Monday... Sunday high pressure sits over the northeast with light winds and highs in the upper 30s-40s under a cold airmass; should be a mostly dry day before snow rain chances increase from the west by the evening overnight hours. The upper trough over canada digs south helping to generate a surface low in the vicinity of sne which brings weak fronts through in quick succession Sunday night Monday. Still expecting mainly snow outside the coastal plain, with rain along the coasts. QPF amounts are lackluster; a few hundredths to a few tenths of liquid equivalent. Tuesday through Thursday... after the system exits zonal flow returns at the base of a large 500 mb trough over the eastern us Tuesday early Wednesday. Some disagreement on slight precip chances Tuesday, but overall looks dry; maybe some showers over the high terrain. By mid week a |
surface high returns bringing dry weather. Given the overall weak longwave trough pattern, cold temperatures will persist with highs in the 30s and low 40s. Aviation 18z Friday through Wednesday Forecaster confidence levels... low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent. Short term through Saturday night ... this afternoon... Moderate to high confidence. Mainly MVFR ceilings early this afternoon with ifr conditions focused across the CAPE islands. We should see conditions improve through the afternoon to mainly MVFR with even someVFR conditions at times. NW wind gusts of 20 to 25 knots in most locations, with some 30 to 40 knots on the CAPE islands should gradually diminish through early evening. Tonight... Moderate to high confidence. MainlyVFR but some marginal MVFR CIGS possible at times especially across the interior. Westerly wind gusts diminish to between 15 and 20 knots. Saturday and Saturday night... High confidence. MainlyVFR but some marginal MVFR CIGS are possible generally during the daylight hours across the interior. Westerly wind gusts up to around 20 knots are expected Saturday afternoon. Kbos terminal...

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
