This weekend has been pretty nice across the country, with little in the way of watches or warnings or intrusions of cold air or wet weather. Unfortunately, it is only late November, and winter is not yet cancelled.
In fact, there maybe a couple of features that bring wet weather and less pleasant conditions to the country this week. First, early this week a feature will come out of the Rockies and move into the Plains, bringing rain, snow and cooler air to the middle of the country.
The feature will shift towards the Great Lakes, with showers and thunderstorms south from the Ohio River, and a real possibility of lake enhanced snow mid week before shifting out through New England late in the week.
A couple of other surges of wet weather will be possible with a feature arriving in the Pacific Northwest on Tuesday, which might lead to some significant problems in the mountains for casual travelers, but probably not those that are used to it.
Late in the week, a system will develop in the Lower Mississippi Valley with cold air driving in from the northwest. It will predominantly be a rain maker, initially in Mississippi and Louisiana, but shifting northeast before clobbering the Ohio Valley again, and eventually the entirety of the Eastern Seaboard. Again, it should all be rain at least through next Sunday, with some thunder further south.
Now, as for the beginning of December. A developing area of low pressure in the mid-Atlantic might make things a bit more wintry. But we’ll talk about that again at a different time.
