(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kgyx 260650 afdgyx area forecast discussion national weather service gray me 250 am edt Mon aug 26 2019 Synopsis High pressure will remain across region through the first half of the week. This will provide dry weather and seasonably cool temperatures. A cold front will move in Wednesday night and cross the area Thursday with a chance of showers. High pressure builds quickly by on Friday with another front arriving by Saturday morning. Near term through today Sfc high pressure will stay put across new england today providing for another fair weather day with temperatures mainly in the 70s. Strengthening upper level low pressure just off to our east will continue to move northeastward as well, keeping us on the dry side of it. This will allow for mostly sunny skies, although a period or two of bkn clouds may occur. A seabreeze is expected to move onshore this afternoon. Short term tonight through 6 pm Tuesday High pressure at the sfc remains across the region tonight. This will set the stage for another radiational cooling night with valley fog expected late. Not much change for Tuesday as high pressure very slowly slips off to the southeast. Aside from some increasing cirrus, mostly sunny conditions are expected. Highs will be a bit warmer than today's, reaching the mid 70s to around 80 at many locations. Long term Tuesday night through Sunday Broad upper trough over central north america will gradually shift eastward with time. The core of the upper low tracks northeast well north in canada while the lower trough axis moves into new england Wednesday night into Thursday along with a surface cold front. Another spoke of energy rotates through the upper trough sending another cold front into new england Friday night. Tuesday night could be another good radiational cooling night, though there is the potential for increasing clouds to put a cap on the cooling overnight. Wednesday sees a southerly flow ahead of the approaching cold front. Moisture return with this front is rather paltry by summer standards and the best lift will be well to the north. In fact, the front loses some of its push as it arrives Wednesday night and takes through Thursday to finally clear the area. We should expect scattered showers |
mainly in northern areas, but it will not amount to much total rainfall. One complicating factor is tropical low that gets pulled up the east coast on Thursday. When this moisture gets pulled into the frontal boundary it will provide a more significant rainfall, but this looks like it will happen to our east. Surface high pressure axis crosses the area on Friday with the next cold front arriving quickly from the northwest Friday night. Again the moisture return with the front is quite lacking, so don't expect much precipitation other than a stray shower. Dry high pressure builds in behind it. In fact, if gfs materializes dewpoints could be falling into the 30s which could set up some cool nights for the first few days of september. Aviation 06z Monday through Friday Short term through Tuesday ...VFR. Localized ifr conditions are likely between 08-12z at kleb and khie Monday and Tuesday morning in stratus and fog. Otherwise clear withVFR conditions. Afternoon seabreezes at the coast. Long term... Should stayVFR through Wednesday, though some morning fog is possible in the valleys. A cold front crosses the area Wednesday night into Thursday with a few showers as it does so. Marine Short term through Tuesday ... Onshore flow continues through Monday with gradually building seas. Winds should stay below 25 kt but seas will likely reach 5 ft tonight into Tuesday morning for the open waters south of casco bay. SCA for seas around 5 ft remains in effect. Long term... High pressure over the gulf of maine Tuesday gives way as a cold front approaches from the west and tropical low pressure moves north through the western atlantic on Wednesday. The low should pass to the east of the gulf of maine on Thursday. High pressure quickly crests over the east coast on Friday with another cold front arriving by Saturday morning. Gyx watches warnings advisories Me... None. Nh... None. Marine... Small craft advisory for hazardous seas from 11 pm this evening to 8 am edt Tuesday for anz150-152-154. |
