Forget the fiscal cliff...our temps just jumped off the meteorological cliff. Yowza---when you factor in the wind chill this morning, it feels nearly 40 degrees colder right now compared to yesterday at this time (5am).
The good thing about all the new-found cold air is the fact that it is dry so you have sunshine for the day. Despite all that sunshine, temps will crawl to 40 by afternoon. A fiesty northwest wind this morning will fade by afternoon--all in all, a nice early winter day. Skies remain mostly clear this evening before more clouds arrive after midnight. Evening temps into the 20s.
Friday offers more seasonable temps with afternoon highs reaching the mid & upper 40s. The reason for the milder day is our next storm approaching as it will push slightly warmer air into New England. This storm will also push clouds into our skies throughout the day and eventually some rain showers late in the day.
The weekend....everybody works for it and hopes for sunshine too. Outta luck here kids as a slow moving storm lolly-gags through the northeast both weekend days. That means each day offers clouds and a few showers each day---Saturday's chance of rain is a little higher than Sunday's (70% versus 40%). Sorry snow-lovers, no cold air for this weekend storm so just raindrops...no snowflakes. Hang in there.
Although my forecast was busted today, there was one good thing that came out of it.
That gray overcast that hung over the eastern half of the Commonwealth provided a stablizing influence to our atmosphere. The cool air blowing in from the ocean kept the temperatures in the upper 50s and low 60s all the way back to Metrowest. While that makes for lousy short-and-t-shirt weather, it is poison to thunderstorms.
Wild temperatures yesterday---from the 80s down into the low 60s in just an hour AND some heavy duty thunderstorms. The reason was a cool front that dropped in from Maine. That front is in western New England this morning and it's a chameleon as it will become a warm front and try to warm things back up during the day.
You have another warm & humid day with many towns repeating yesterday's weather. That means we start with clouds & fog for a bit before hazy sun gets going. That hazy sunshine will boost temps up into the low 80s by early to mid afternoon across much of the region. At the same time a cool front will begin dropping out of Maine (backdoor front) which will quickly send temps from the 70s/80s down into the 50s/60s by late afternoon & evening. Also, when this front rams into the warmth & humidity it will spark a few showers & thunderstorms during the afternoon.
