PHILADELPHIA (WPVI) --A lot of instability clouds developed today in the cold airmass overhead. Those clouds, along with northwest winds gusting to 30mph. made for a chilly Tuesday with temperatures only reaching the low to mid 50's across the area.
TONIGHT: Any clouds will dissipate and we'll see clear and cold conditions with winds diminishing. This will allow temps to drop into the upper 20's in the northwest suburbs to mid 30's along the I-95 corridor. As a result, most of the viewing area is under a freeze warning from midnight to 9AM on Wednesday. In Philadelphia and the highly urbanized areas around it we are under a frost advisory during that same time. People in the freeze warning area need to bring in any potted plants they want to save and its also a good idea to drain hoses and shut off outdoor water spigots.
WEDNESDAY: With high pressure nudging down from the north, we'll start off with sunshine, but high clouds will increase as we head through the afternoon into the evening as our next storm approaches. The high dips to 53.
THURSDAY: As that frontal system heads toward us from the Ohio Valley, light precipitation could begin near dawn on Thursday, mainly for areas north of Philadelphia. This could for a brief time be a wintry mix or light snow for areas of the Poconos on northward before changing to rain, so keep that in mind if driving that way. For the rest of us, Thursday will be a wet and dreary day with highs stuck in the 50's and periods of rain throughout the day. None of it looks exceptionally heavy with just a 1/4" to 1/2" expected. Definite signs of winter well to our north, where the Catskills could see a few inches of snow! Winter is not very far away. The high rebounds to 58.
FRIDAY: As that storm exits into New England, we'll get a gusty breeze on its back side under partly sunny skies. The high is a relatively cool 57.
SATURDAY: The track of the weak system passing through on Saturday has shifted to our north instead of coming right over us. This means a diminished threat for showers and more in the way of sun with temperatures climbing to 65.
SUNDAY: Late October warmth moves in, with a high soaring to 75. Some late showers are possible ahead of a cold front.
MONDAY (HALLOWEEN): We have clouds mixing with occasional sunshine and a high around 64. Evening conditions for trick-or-treating look dry and seasonably cool for now, with temperatures in the mid to upper 50's.
TUESDAY: We have a nice, partly sunny day with an afternoon high of 66.
