After starting off with dense fog(freezing fog in the suburbs) we broke out in sunshine before clouds rolled back in by the late afternoon; the high at Philly International Airport was 48(set at 3:49pm) after a low of 35(at 6:42). I hate the be the bearer of bad news, but today's high will be the warmest high out of the next seven....
You knew it couldn't last forever!
Overnight on Wednesday there will be a frontal boundary pushing through providing some rain showers(snow north and west where temperatures will be below freezing) with lows in the middle and upper 30s. Behind the front there is no real cold air so this will lead to Thursday being overcast with snow showers to the north. Highs elsewhere will be in the middle 40s.
Friday will start off sunny with highs in the upper 40s, but then we cloud up in advance of another cold front; overnight Friday into Saturday morning temperatures will be around the freezing mark so we'll have some rain to snow showers with little accumulation on the grass and colder surfaces with highs eventually reaching the upper 30s by Saturday afternoon.
Sunday will be sunny and seasonable with highs in the lower 40s, but then on Martin Luther King, Jr. Day we'll cloud up once again with another system on tap for Tuesday; behind this system will be very cold Arctic air with highs dropping on Wednesday and even some snow showers.
That's it for now and remember you can check out the rest of the seven day forecast (any time) at www.scottderekwx.com/forecast.html.
