Night Report
Just a quick follow up on the little winter event Monday in our region. I have heard from a lot of people thinking this will not happen, simply because we have had two days in the 60s. There have been many times I’ve seen a quick turn of weather like this which is why I wanted to let you know and avoid a surprise.
Notes:
- I also want to reiterate that most of our region will likely have roads remain wet, but there could be some slushy coating on the grass west and north of Baltimore.Especially with a burst of snow for at least an hour or two.
- Onset time between 7 to 10 AM.
- Frontogenesis: We will be watching rapid development of the precipitation forming over our region as a warm front takes form.
- Our temps may drop as it begins, then remain steady into the early afternoon. It will be warm air at cloud level that does all the work.
- This may begin as rain or sleet, then turn to slushy snow burst, then back to mix and rain.
