NAM Model's forecast lows tonight

An absolutely gorgeous Monday is wrapping up as we type this evening, and the skies remain relatively clear.  Today featured plenty of sun and warmer temperatures, approaching the upper 60's to 70 in many locations. Although the winds were east, they remained relatively light. Helping the situation, high clouds generally held off for the day and the early evening. Over the next several hours, though, you'll begin to notice their presence. They are moving towards our area in advance of a mid level disturbance in the atmosphere which is currently over the Central United States, but is shifting towards the Northeast US. As it does so, clouds will increase tonight into Tuesday morning, and a warm front near the area on Tuesday will enhance the chances for showers and isolated thunderstorms. More importantly, clouds will be around for much of the day..keeping temperatures again in the middle 60's, and the air generally less comfortable. The lack of sun certainly won't help things. That being said, we'll all try to enjoy the next few hours of pleasant weather through tonight. Low temperatures tonight aren't forecast to be as cool (actually, nearly 10 degrees warmer in the city)..with lows in the 50's to around 60 in the metro.

THE FORECAST...

Through Tonight: Partly cloudy early, then increasing high clouds which will eventually lower and thicken. Low temperatures in the upper 50's to near 60 in the city, and mid 50's elsewhere. There is a chance of a spotty shower after midnight.

Tuesday: Mostly cloudy with showers possible throughout the day. High temperatures only in the mid 60's. With east winds around 10 miles per hour, it certainly won't be the most pleasant day.

LOOKING AHEAD TO MID WEEK...

The forecast takes a highly unsettled turn as a low pressure system over the Central US moves towards our area the middle of the week. Wednesday will be the warmest day, with temperatures rising into the middle 70's. However, clouds and the potential for showers will muddle up the forecast. This will continue through Friday--before the system looks to move out for the weekend.
