what do the temps look like for this weekend in nw nj my national weather forecast says upper 50's do you think that's low considering strong sun this time of year

10 degrees too light in the day. Temps mainly 65-70 during the day and 70-71 in the hotter spots. Cool nights though as this is a cool Canadian high that may promote frost in cold spots. Big swings in temps from morning lows to 4-5PM high temps this weekend. Then look out because Canadian highs as strong as this one sail SE and anchor off the coast at this time of year and that cool high (you judge cool highs by night temps in May) will then becoms a heat pump and could easily push temps to the 90's mid and late next week.
