The overnight temperature didn’t drop as much as I expected. The early arrival of clouds was responsible for that. Right now we are around 30 degrees in southern warren county. Other locations are in the mid to upper 20’s to the north.
Temperatures 8 am Thursday morning
Many school districts have early dismissals today.
Radar 8:30 am
The radar show the approach of the wintry precipitation. Take note that the light snow just to our SW is not yet reaching the ground. This is common in the winter time when the atmosphere is cold and dry before a storm. It takes a little bit for it to moisten up enough for the precipitation to reach the ground.
Once the snow changes to rain, we expect the total liquid from this storm to be over 1″ and possibly even 1.5″ in some spots. So a lot of the frozen precipitation on the ground will get washed away in some spots
Timing: Look for snow to arrive in western New Jersey between 10 am and 1 pm from SW to NE. Don’t be surprised to see the snow go to sleet after it starts and then back to snow. This is due to the warmer temperatures before the snow. ONce the snow starts it will cool off the temperature.
Sleet will start mixing in and even change over starting as early as 4pm to around 7 pm.
Rain will start mixing in and then changeover around dinner time in the southern areas to 10 pm further north
NWS snow forecast
How Much: The NWS has maintained their snow forecast of 2-3″ for most of western New Jersey with a bit more further north. My thinking is the sleet will arrive sooner and keep totals down to a coating to 2″ with more to the north.
Don’t be surprised if the rain ends as some wet snow early Friday morning as colder air comes in behind the departing storm. Quieter weather is expected for the next several days
