HUMID AIR ACROSS THE REGION HAS ALLOWED DENSE FOG TO FORM IN MANY

LIKELY PERSIST ALONG THE COAST. SKIES WILL REMAIN MOSTLY CLOUDY
TODAY WITH STRATUS TO THE SOUTH AND STRATOCUMULUS ACROSS THE
NORTH. A WEAK WEATHER DISTURBANCE TRACKING ALONG THE BOUNDARY TO
OUR SOUTH WILL BRING SHOWERS TO DOWNEAST AREAS TODAY. THIS WILL
GIVE WAY TO A MOSTLY CLOUDY NIGHT TONIGHT. A LARGER WAVE OF LOW
PRESSURE WILL APPROACH LATE TONIGHT SPREADING RAIN INTO THE AREA
AFTER MIDNIGHT. MOST OF THE RAIN IS EXPECTED ACROSS CENTRAL AREAS
WITH MODELS DIFFERING ON HOW MUCH RAIN WILL MAKE IT TO THE NORTH.
