Marine Weather and Tide Forecast for Kittery, ME

KEY MESSAGES
1. Temperatures again rise into the mid 80s to around 90 for much of the coast and areas downwind of the mountains, but highs are not expected to be as hot as Tuesday. A cold front moves through during the day with the potential for a few gusty showers or thunderstorms.

2. Potential for frost Thursday night away from the coast.

3. The second-half of the week will feature cooler temperatures and drier conditions. This weekend looks to stay mostly dry with more unsettled weather potentially incoming for early next week.

DISCUSSION
KEY MESSAGE 1 DESCRIPTION...

A cold front will move across the forecast area today. However timing will not be optimal for widespread strong to severe thunderstorms. Nevertheless, given high temperatures well into the 80s to near 90 on the coastal plain and across southern NH (with attendant steep low level lapse rates), a few strong wind gusts with isolated storms will be possible. Gradient winds will also be gusty, with gusts outside of any showers and storms 25 to 30 MPH. Timing of any convective activity will be late morning through early-mid afternoon for most zones.

A much cooler air mass arrives for tonight and Thursday with dry weather expected.

KEY MESSAGE 2 DESCRIPTION...

Lowered min temperatures closer to MET/MAV consensus for Thursday night with dry high pressure moving overhead. This should set up an ideal night for radiational cooling with frost advisories likely needed for many interior zones away from the coast.

KEY MESSAGE 3 DESCRIPTION...

High pressure moves in from the west, bringing cooler and drier conditions. This high pressure will keep more active weather to the south and west of the region. Over the weekend, a low may move into the area and bring meaningful rain to the area. However, high pressure does look to be strong enough to keep any precipitation out of the area until early next week. High pressure starts to slide to the southeast by Sunday and into Monday, with some showery weather possible early next week. High temperatures over the weekend will generally be in the 60s with lows in the lower 40s.

Gusty westerly winds around 25 kt nearshore today is the reasoning for a SCA for today. Offshore winds will be lesser.

Strong high pressure then moves over the region for late week, resulting in mainly conditions below SCA over the waters. Seas of 2-4ft and light, variable winds are expected over the weekend and to start next week.
