After some rain to get out of the way on Friday, a warm St. Patrick's day weekend will be in the cards for most of the region!
Friday will be the worst out of the 3 days this weekend. Rain showers will be spread across the region through most of thee morning and early afternoon Friday. It will not be a washout but the rain will be accompanied by overcast skies and above normal temperatures. Rain should spread from west to east starting around 8am for eastern Pennsylvania and will be light and spotty making its was east through the day. Any leftover rain should clear the coast by about 2-3pm. I would not rule out some heavier rain or thunder for Cape Cod and southern New Jersey after 3pm. High temperatures will be very warm, in the mid 60s from NYC on west with some areas maybe flirting with 70. However, it will not be that nice for everyone as the cold ocean will keep NYC on east in the low to mid 50s with a sharp cutoff of the higher temperatures.
Overnight will likely be dry with a spot sprinkle somewhere. Lows will be in the 30s for all of the region.
Saturday will be seasonably slightly above average with high expected to be in the mid to high 40s along the coast and further south. This is about 2-4 degrees above normal for this time of year. Further inland is more tricky. Some models have cold air sticking around while others open the flood gates for warm air to pour in. Right now I am expecting for inland areas away from the coast to be in the high 30s and low 40s. Saturday will be completly dry besides a spot flurry for points well north west and in higher elevations.
During the nighttime hours on Saturday, expect lows below freezing with temperatures crashing down to the low to mid 20s in areas away from the coast. No rain or snow is expected.
Sunday will be an average day with highs in the low 40s for most of the region. This is right about average for this time of year. Further to the north and west, highs will not vary much and only be a few degrees colder compared to coastal areas. The day will remain completely dry with high pressure dominating our region.
Overnight, there is expected to be a weak low pressure developing that drops some snow across eastern Pennsylvania to Long Island. As f right now it does not look like much maybe an inch or so. It will be a nice look to coast the ground into Monday morning. There is a chance it may be the last snow of the year. Lows will be right around freezing for all.
