Getting Colder...
The last time we saw rain was last Thursday...nearly a week ago and this time around it was another soaking with many towns gathering around or even over .5". The rain isn't quite through but later tonight a coldfront will pass...shutting off the rain and delivering much colder air by morning. In fact, tonight's low temps will be tomorrow's high temps and the air will be getting colder throughout the day. This will present an interesting scenario tomorrow evening.
While the front will have cleared the coast, it won't get that far in fact light rain showers may actually fall over the Cape most of the day while the rest of us will be cloudy but raw. Along that front, there is going to be some surface low pressure development spawned by and approaching shortwave this will bring some of that backlash rain westward and as the upper level feature passes overhead later in the evening will also create an unstable atmosphere for showers to develop. The thing is, the air will be much colder when this happens and wet snowflakes may actually mix in with the cold rain drops. It's kind of a race between the cold and precip but if they line up...snowflakes may be in the air tomorrow evening. Of course, no accumulation will occur.
The core of this brief blast of cold will move through on Friday and highs will only be in the mid 40s with windchills in the 30s. But just like all other cold airmasses this Autumn, it won't last and a warm up will ensue over the weekend with highs in the 50s on Saturday and 60s on Sunday!
