Marine Weather and Tide Forecast for Rockland, ME

NEAR TERM /UNTIL 6 PM THIS EVENING/
Light onshore flow and cool temps this morning have allowed areas of radiation fog/stratus to form across the interior. This will scatter out after sunrise and lead to a mostly clear day with warmer temps than yesterday.

That shallow moisture should lead to some cumulus development across the interior this afternoon. An isolated shower is possible in the mtns...but widespread precip is not anticipated.



SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/
Based on little change in overall flow pattern and areas of fog/stratus this morning...I am expecting fog to form again tonight. I have added fog to the coastal waters and nearshore areas...but I could see this expanding inland as well. For now I have this mainly just a stratus deck.

Much like today...isolated showers will be possible in the higher terrain Mon but otherwise it will be a dry day. Temps will also be a little bit warmer as well.

LONG TERM /MONDAY THROUGH FRIDAY/
Evening Update...No significant changes to the long term period with the inclusion of the latest long range NBM. A warming trend with chances for afternoon thunderstorms continues to be the story for the coming week.

Previous Discussion...
No big changes to the going forecast as the 12z deterministic and ensemble suite are in reasonable agreement and showing decent run to run continuity. The main theme will be high pressure hanging out just offshore early next week which will mean southeasterly winds over the land with the potential for a good amount of clouds. The onshore flow will keep temperatures somewhat down as well. The high is modeled to move farther out to sea mid week, allowing for more of a southwesterly flow regime to take shape. This should allow for more summery weather with temperatures well into the 80s by Thurs along with increasing chances of afternoon thunderstorms.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/



AVIATION /07Z SUNDAY THROUGH THURSDAY/
Short Term...Light onshore flow and cool temps have allowed some local fog and areas of stratus to develop this morning. LIFR conditions will linger thru sunrise before scattering out to VFR. Another round of low CIGs and patchy fog is possible again tonight near the coast.

Long Term...VFR likely prevails through midweek next week, with nighttime valley fog possible each night. Marine fog is possible at RKD by midweek as the airmass moistens. Chances for scattered afternoon showers and storms increase across interior terminals starting Wednesday and continue through late week.
More widespread showers and storms are possible late Thursday or Friday.

MARINE
Short Term...High pressure will build over the coastal waters thru the early part of the week. Light onshore flow will promote the gradual increase in low level moisture and areas of fog.
While confined mainly to the land areas near the coast this morning...fog over the waters will become more likely starting this evening.

Long Term...High pressure gradually moves eastward across the North Atlantic through midweek next week with generally fair conditions. However, fog will be possible. A cold front approaches late in the week, with SCA conditions possible in southwesterly flow ahead of the front by late Wednesday.
