Synopsis for stonington me to merrimack river ma out to 25 nm.. A cold front will cross the region today and will be followed by high pressure building in from the west overnight. High pressure will crest over the region on Tuesday before shifting offshore to the southeast. A weak disturbance will push east through southern new england late Tuesday night and early Wednesday. Weak low pressure will slowly move northeast through southern quebec Wednesday night and will drive a trailing cold front through the region after midnight. A secondary trough of low pressure will drop southeast through the region Thursday night and Friday. High pressure will gradually build in from the west over the weekend. &&

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kcar 191406 afdcar area forecast discussion national weather service caribou me 1006 am edt Mon aug 19 2019 Synopsis A warm front will lift northward across the area today. A cold front will cross the region tonight. High pressure will move across the region Tuesday. A cold front will approach later Wednesday then cross the region Thursday. Another cold front is possible Friday. Near term through tonight 10 am update: upgraded thunderstorms coverage for coastal zones and coastal waters for the complex moving along the coast this morning. Added damaging winds to the forecast for northern somerset, piscataquis and much of penobscot counties. Southern piscataquis county still seems like the area where severe parameter line up best. Metsat imagery showing clearing in large portions of nh vt southern quebec where SBCAPE can develop this afternoon. Mode appears to be a line that will move across southern piscataquis and into southern central penobscot. Thus damaging winds would appear to be a potential consequence. The line will weaken as it enters a more stable environment in the penobscot river valley and points eastward. Prev disc: low st cld cvr and patchy to areas of fog have moved into all of the fa xcpt the far NW from nb very erly this morn. Meanwhile, a left ovr area of shwrs associated with a weak S wv from the great lks is about to cross into downeast and cntrl highlands areas, with most of this activity xpctd to weaken if not dissipate before crossing into nb prov. Skies will be slow to exhibit much in the way of prtl sunshine this aftn due to the amt of moisture in the lower wx atmos. Another S WV and associated cold front xpctd to arrive from cntrl can will bring another round of shwrs tstms to mostly wrn ptns of the fa later this aftn into erly eve. Decent 0-6km bulk shear vectors alg with MAX sbcapes of 1000 to 1500 j kg ovr the initiation zone near the ERN qb WRN me border could result in a couple of bowing ln segments as stms enter WRN me mid to late aftn with brief torrential rnfl rates and strong gusty winds. Any TSTM gaining mid lvl rotation could also produce hail despite relatively high fzls. Although rnfl will be lcly hvy, tstms should cove with the faster forward corfidi vector motion, lmtg the potential of prolonged hvy rnfl. Tstms should weaken some as the move into ERN and downeast ptns of the fa toward erly eve due to stabilization of the lower atmos due to marine or modified marine air ovr these areas. Otherwise, shwrs and tstms will end wnw to ese behind a cold front late this eve into the ovrngt as a cold front crosses the rgn with late ngt clrg as slightly drier air moves into the rgn on NW winds. Short term Tuesday through Wednesday night Drier on Tuesday, but warm as high pres settles across the region. Daytime temps are forecast to reach into the 80s. The high will remain in control of the region's wx right into early Wednesday. It will become more humid on Wednesday as a return flow of southerly winds will bring in higher dewpoints and increasing clouds. Daytime temps will be warmer across the northern and central areas W lower 80s, while the south wind keeps the bangor region and downeast a tad cooler. The latest set guidance including the gfs,ecmwf and NAM have pushed back the timing of the showers light rain W the apchg warm front til Wednesday evening. The canadian guidance was faster and wetter showing the potential for some heavy rainfall into the eastern areas. At first, the thought was that this could due to some convective feedback, but looking further into it, there appears to be a nose of warmer that pushes up into the region Wednesday night W the warm front. The GFS does show a jetstreak of 30 kts at 925-850 mbs W some elevated cape, but it puts the heavier rainfall over the western areas. The ECMWF has its jet dynamics well to the east and does line up W the heavy rainfall potential. Tstms were kept in the forecast given the elevated CAPE and that warm nose, but given the discrepancy on the placement and amounts of the rainfall, confidence is low on adding any enhanced wording for heavy rainfall attm. The daycrew will need to assess this further today W the later guidance. Fog was added as well due to the southerly flow and moist llvls. Long term Thursday through Sunday |
The associated cold front is forecast to move across the region during the day on Thursday. Showers and fog in the morning will limit instability. There could be a window of opportunity however by late Thursday morning as a pre-frontal could move out ahead of the cold front W some warming noted by the GFS and ecmwf. This will allow for rapid destabilization W decent cape potential. There is good shear ahead of the front W some difluence aloft. This should be enough to get some tstms going. Another thing to note is the strong upper jet helping enhance development. Stayed W the daycrew's thinking of tstms W the best potential ATTM being across the northern and western areas. It will be interesting to see how things move as the new guidance comes in. The cold front is expected to clear the region Thursday night w much cooler air on the way for Friday right into the weekend. The long range guidance including the GFS and ECMWF show the upper trof remaining across the region into Saturday. This will allow for clouds to develop during the day. A disturbance moving through the trof on Friday has the potential to produce some showers mainly across the N and w. Decided to go W 20-30% for precip chances. There could be a few showers still around on Saturday as we remain under the trof. Used a blend apch and have a slight chance(20%) for a shower or two. Aviation 14z Monday through Friday Near term: another early morn of vlifr to lifr clgs vsbys in st cld cvr and fog across our TAF sites. Clgs and vsbys will again slowly rise back to MVFR and even lowVFR by erly to mid aftn as the dwpt depression increases. Clgs and vsbys will briefly lower to MVFR or even ifr at TAF sites experiencing tstms and or heavier shwrs later this aftn into erly eve. Otherwise conditions will become unlmtdVFR by late tngt, after perhaps a brief pd of low st and patchy fog ovr downeast mid to late evening before llvl cool advcn behind the cold front drives out remaining llvl trop moisture. Short term: Tuesday...VFR all terminals. Wednesday... GenerallyVFR W low clouds moving into bgr and bhb by the evening. Wednesday night... MVFR to ifr W some showers and fog setting. Tstms are possible. Thursday... Ifr W fog and leftover showers drizzle for all terminals. Improvement by late morning to MVFR andVFR as the cold front apchs from the w. Showers and tstms expected by the afternoon which could drop conditions briefly to MVFR and perhaps ifr. Friday...VFR W occasional MVFR possible across the northern terminals. Marine Near term: locally dense marine fog will continue tdy and a good ptn of the ngt until offshore winds behind a weak cold front dries the bl by erly morn tue. Went with about an 80 percent of ww3 nwps guidance blend for fcst WV hts, with recent obsvd buoy wv hts a little less than guidance. Most sig spectral WV pd groups still include a 6 to 7 sec nwrd propagating regional short wind fetch group and a 10 sec nwwrd propagating background swell group from the open N atlc ocean. Short term: wsw winds around 10 kts will back to the ssw on Wednesday. Seas will average around 3 ft W a gradual buildup to 4 ft by Wednesday night. Visibilities will be reduced in fog Wednesday night. SW winds will increase to 10-15 kt on Thursday ahead of the apchg cold front W wind veering to the W later Thursday night into Friday. Gusts could apch 20 kts especially for the outer zones. Car watches warnings advisories Me... None. Marine... None. Near term... Vjn short term... Hewitt long term... Hewitt aviation...
