Synopsis for massachusetts and rhode island coastal waters.. High pres centered over the great lakes late this evening will build east over quebec and northern new england overnight and Sat. The high will shift east toward the canadian maritimes Sun and linger there through mid week. A tropical depression is likely to form off the coast of florida early next week. This system may track close enough to effect the coastal waters by mid week with elevated seas. For information on possible hazardous weather beyond the 24-36 hour forecast period, please visit www.weather.gov/boston and follow the current hazards link above the map on the left.

Area Discussion for - Boston, MA
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kbox 240149 afdbox area forecast discussion national weather service boston norton ma 949 pm edt Fri aug 23 2019 Synopsis Canadian high pressure will bring drier and less humid air to new england and eventually a fall-like airmass this weekend. Expect mild afternoons and cool nights with dry weather Saturday followed by possibly a few showers Sunday especially eastern ma into ri, but a washout is not expected. High pressure settles over the canadian maritimes early next week supporting dry cool weather here along with breezy conditions across CAPE cod and the islands. Meanwhile we'll be watching a potential tropical system tracking from the bahamas to well south of new england early to middle of next week. Near term until 6 am Saturday morning At 930 pm, satellite showed thicker mid and high clouds over ri and SE mass, shifting east and offshore. Thinner clouds over the interior were also shifting to the east. 9 pm observations showed north winds at 10 mph or less, mostly less. Dew points in the comfortable 50s along north of a boston-hartford line and 60-65 over southern ri and SE mass. Trend for the rest of the night will be for clear or clearing skies. With light winds and clear clearing skies, expect min sfc temps to reach the 50s in the interior and 60-65 along the coast. Short term 6 am Saturday morning through Saturday night 350 pm update ... Saturday ... 1025+ mb high over ontario advects eastward into quebec, providing a dry nne flow into southern new england. Expect highs in the 70s and dew pts in the upper 40s to lower 50s. Definitely a touch of early fall in the air. Cross sections reveal some cirrus and diurnal CU scu so expect a mix of Sun and clouds Saturday. Overall a real nice day by late aug standards. Saturday night ... northeast pressure gradient increases as frontal wave develops well south of new england but combines with 1030 mb high (yeah a sign of early fall) over the maritimes. Thus becoming breezy and with a surge of wind and moisture off the atlantic expecting scattered showers to come onshore especially toward Sunday morning and over eastern ma into ri. Remainder of the region should remain dry until Sunday. Long term Sunday through Friday 350 pm update ... highlights... * expect much cooler than normal temperatures Sunday and Monday especially along the east coast * onshore winds will bring spotty light rain or showers at times into mid week * temperatures return to near normal levels around mid week * another chance for showers late Wednesday into Thursday details... Sunday through Tuesday... this period of the forecast will feature mostly dry conditions with cooler than average temperatures throughout and comfortable humidity. Sunday we see the high over northern new england shift east a bit, bringing northerly winds around to the northeast. While most of the column is very dry, below 850mb moisture advection off the ocean will bring some low level cloud cover and light showers or drizzle. The only locations that should deal with this would be eastern ma into ri with clearer skies to further west. Not a washout by any means, but could see scattered drizzle. A tightening pressure gradient on the south end of the high will bring increasingly gusty northeast winds, especially on the southern waters and along the south coast where gusts will reach 25-30 mph. Those on the water will likely see increased seas as well. Temperatures are quite a bit below normal given h85 temps of 8c and onshore flow... Those along the east coast may not make it out of the 60s. Monday and Tuesday the inverted ridge of high pressure lingers over sne helping keep things dry while the mid level low moves out replaced by weak ridging. Mid level height rises and some drying at the low levels should keep us mostly precip free, but with lingering low mid level clouds each day. Onshore E NE flow continues throughout keeping the immediate east coast cooler. Highs remain in the low 70s, 5-10 degrees below average for late august. Comfortable humidity sticks around too, with dewpoints in the 50s to low 60s. As the high moves away the gradient relaxes and the gusty winds along the south coast should subside through the day Monday. Wednesday through Friday... high degree of uncertainty with how mid-late week plays out, dependent on the trajectory of two low pressure systems, including one potential tropical system currently in the early stages of development off the coast of florida which may pass sne somewhere off the coast around mid week. At this point confidence is increasing that we'll see temperatures moderating back toward normal by Wed thur into the 70s and 80s as a warm frontal boundary moves north. This, associated with a large low pressure system moving into the hudson bay area. Ahead of its cold front warm moist air is pulled up over the east coast Wednesday Thursday bringing rain and thunderstorm chances back to the forecast late Wednesday and Thursday. At this point the system off of florida looks to stay well offshore of sne, phasing with the passing trough over the maritimes |
by late week. This should limit any impacts in southern new england to potentially some higher surf and rough seas, but given that this is still 5-6 days out, much too soon to get into any details... Something we will be monitoring over the next week. Aviation 02z Saturday 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 ... Moderate confidence. Tonight ... VFR and dry weather with light nnw winds. Saturday ... VFR with nnw winds becoming nne.

High - greater than 60 percent. Short term through Saturday night ... High confidence. Tonight ... large high pressure moves from the northern great lakes into ontario providing dry weather across the southern new england waters along with a modest nnw wind. Observed seas at 9 pm were 3 feet or less. All of this continues overnight. Saturday ... large high pressure moves from ontario to quebec with modest nne winds but dry weather continues. Saturday night ... a series of weak waves of low pres develop off the mid atlc coast. This combines with strong 1030+ mb high pres over the maritimes to yield NE 20-30 kt across the southern new england waters. Strongest winds likely south of CAPE cod and the islands. Scattered showers may lower vsby at times. Outlook Sunday through Wednesday ... Moderate confidence. Sunday: low risk for small craft advisory winds with gusts up to 30 kt. Seas up to 5 ft. Slight chance of rain showers. Sunday night: low risk for small craft advisory winds with gusts up to 25 kt. Seas up to 5 ft. Monday: low risk for small craft advisory winds with gusts up to 25 kt.
