Most of us are waking up to (actually Mainers are super early risers so more like "having a second cup of coffee to..") cloudy skies on this Sunday; but the day will turn out to be decent for the vast majority of the state.

The current low level clouds will start to burn off by late morning and after that a mixture of sun and clouds will dominate. The general rule will be: the farther north you head, the more sunshine. As such, York and Cumberland counties may struggle with the low cloud cover through much of the day...with only "breaks" of sunshine. From Lewiston north the afternoon will be fairly pleasant with partly sunny skies and temperatures in the low to mid 60s. However southern Maine will deal with a warm front late in the afternoon which will spread showers into Portland by about 3 PM and into the Midcoast by 5-6 PM. By the way, with a strong onshore flow the coastline will only reach highs in the upper 50s.

Showers will spread from southwest to northeast overnight as the warm front travels through Maine. Most of the shower activity will be fairly light, but it WILL be widespread by late evening/early morning. With high relative humidity values I wouldn't be shocked to see some fairly thick fog developing.

Monday will be a dreary and wet day as the aforementioned warm front will park itself right over central Maine. As a result look for mostly cloudy skies, some coastal drizzle and off and on showers through the day. High temperatures will be surprisingly mild due to the airmass in place, in the low to mid 60s in most spots...some isolated upper 60s.

The warm front will sag (doesn't sag have such a negative connotation? When has "sag" ever been used in a positive sense? BAM it's about to happen...) to the south on Tuesday, bringing the clouds and showers with it. Partly sunny skies will be the rule through the day and temperatures will push into the low 70s in many spots. Probably the best day of the week.

Back to some showers on Wednesday as the warm front pushes back into our hood.

We will deal with the wiggle of this warm front all the way through the end of the work week, so I expect generally unsettled conditions.

At this point Memorial Day weekend looks MIGHTY cool to me.

And not in a James Dean kinda way.
