&& .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/... Pressure gradient continues to slowly break down as sfc ridging to our NW slowly noses in tonight. This should once again allow for decoupling to occur, probably in more areas than Sunday morning. However, air mass will be a little warmer, so, although it will another cold night, it will be a few degrees warmer than this morning. Monday will again see sunny skies, and lighter winds, but probably still on the order of 10-15 mph. Temps won`t vary much from Sunday, although highs could be a couple degrees warmer. && .LONG TERM /MONDAY NIGHT THROUGH SATURDAY/... A trof of low pres will remain over the maritimes through midweek supplying a continued north to northwest flow of cold temps that will be well below normal along with dry condition`s. Late in the week models continue to indicate a southern stream system will be progressive as it moves off the mid atlantic coast and passes well south and east of the area. This will mean a continued dry and cold regime over the area as Canadian high pres remains anchored to the north through Friday supplying below normal temps. && .AVIATION /12Z SUNDAY THROUGH THURSDAY/... Short Term...VFR today through Monday. Winds will not be as strong as Saturday, but to gusts to 20 kts or so are possible this afternoon. Long Term...VFR. && .MARINE... Short Term...Have dropped the SCA for the bays as winds are below criteria, and will likely stay below through today, there is a chance for a few 25 kts gusts late today and this evening, especially in Penobscot Bay. Have extended the SCA through today outside of the bays, although gusts look borderline through midday, should see a surge of NW wind in the afternoon. Long Term...SCA conditions will be likely over the outer waters Wed into Thu as low pres passes well south and east of the area. && .GYX WATCHES/WARNINGS/ADVISORIES... ME...None. NH...None.
