130 AM Update: Mid to upper level cloud cover continues to clear out from north to south tonight as the previous low pressure system presses further east into the Canadian Maritimes. Current Nighttime Microphysics RGB satellite product shows low level fog development in river valleys across the North Woods, and current trends from the KPQI ASOS indicate that fog is building into the valleys over eastern Aroostook county as well. The previous forecast remains largely on track with only minor adjustments based on current observations and trends. Previous Discussion: Sfc low continues to sit and spin over the Downeast coast. Low clouds are very slowly clearing acrs the north and will likely continue to do so this evening as lopres sinks south over the waters. Expecting skies to clear over the north right around daybreak with patchy fog developing as winds become light and variable. Light stratiform rain over the north, though honestly hard to believe much is reaching the ground, will continue to sink south this evening. Further to the south convective showers have developed along boundary over interior Downeast and will continue to pivot over this area remainder of the afternoon and into the early evening hours. Have included isolated thunder with locally heavy rainfall in areas that continue to receive rainfall but overall threat for this is very low. Temps will remain above normal mins for tonight, although the North Woods may be able to drop into the upper 40s depending on timing of clearing skies. Most of the western zones will see sunny skies at daybreak tomorrow while southeastern areas will see showers initially before clearing by noon. High temps over the area likely to top out in the lwr 80s though the shore will only rise to around 70 degrees.
