In addition to any precipitation overnight, there could be some dense fog over SE CT and parts of eastern LI - this will need to be watched as well. Lows tonight will be mostly in the middle to upper 60s.
Short Term - 6am Tuesday Morning Through Tuesday Night
The cold front passes through Tuesday with showers likely through much of the day. Some of these showers have the potential to be briefly moderate at times with an isolated embedded thunderstorm especially in the morning. Showers should persist much of the day as it moves eastward. With overcast skies, highs will likely only get into the low to middle 70s with some warmer spots in the eastern portion of the CWA, especially if there is clearing in the morning.
Conditions will be improving and drying into the afternoon with only a slight chance of isolated showers after 8PM. Afterwards skies become clear for Tuesday night and dew points and temperatures drop behind the frontal passage. Lows will be in the upper 40s and lower 50s for the Lower Hudson Valley and portions of far interior CT. Near the coastline, lows will be in the middle to upper 50s.
Long Term - Wednesday Through Monday
Fair weather Wednesday and Thu as high pressure builds over the region. Temps close to or a few degrees below normal with a Canadian airmass transitioning thru.

Most likely still dry, but some slight chances for showers and tstms have been included per the NBM with some waa aloft beginning. A warming trend can be expected for the weekend as the sw flow strengthens. Humidity will increase on Sun, resulting in higher apparent temps. The warm and humid weather will continue into Monday with little change in the airmass. Shwrs and tstms possible Sun- Mon. Best chances during the peak heating hours each day. The sw flow pattern is usually best for the nw interior zones. Much of LI and CT, especially eastern portions, could be completely dry thru the period. The NBM was generally followed.

SCA (Small Craft Advisory) east of FII is through 22Z Tuesday as seas will be 5-6 feet much of the day. This may have to be extended again into Tuesday night as seas are slow to fall.

Seas may touch 5 ft on the ocean Fri, but the prob is low attm. Conditions otherwise below advy criteria.
