Last Weekend of 2019 Sunny Saturday Rain Sunday Into Monday
We are winding down an interesting weather year featuring all sorts of adventures. This weekend will be split in two and today is definitely the better of the two weekend days. The satellite picture shows us in a good spot today as high pressure north of the Great Lakes is building southward down the East Coast. The air is not cold with this high so we should respond nicely temperature wise today. Highs will reach into the 50s and we will have nothing more than some passing clouds to deal with.
There are no issues to deal with on the radar today and tonight but there will be on Sunday as low pressure heads to the Northern Plains and then stalls out over Southern Minnesota. This system rather than move wholesale northeastward is going to redevelop to the east. This is going to create two issues. The first is that once the rain moves in Sunday afternoon we will be dealing with it in one form or another probably through Monday and into early Tuesday morning. The other issue is for areas from a small portion of Northeastern Pennsylvania northeastward into the Catskills and points northward upstate and into New England. Freezing rain and sleet will be an issue.
For everyone else from Southern Connecticut southwestward to Southern Pennsylvania and New Jersey of course the issue is going to be rain. It will arrive from west to east during Sunday afternoon and last well into Monday. Note the expanding area of ice depicted on the NAM model and if this verifies we could see a significant ice storm for interior New England and parts of upstate New York.
Rainfall amounts from this system will be in the 1 to 2 inch range over much of Eastern Pennsylvania to Southern New England. This will cap off a very wet December with many areas getting 1/2 foot or more of rain and at least double the average for the month.
The low is forced to redevelop and eventually low pressure forms off the New Jersey coast Monday night and finally early Tuesday morning it will pull away to the northeast. This should bring slow improvement Tuesday and the new year arrives dry with Tuesday temperatures in the 40s and nighttime temperatures in the rather reasonable 30s. New Years Day will feature some sunshine a gusty wind and highs just into the 40s in most places.
If you are travelling north this weekend and early next week, snow forecast maps for all of New England are available on my free weather app.
