Flurries tonight, Monday night is still a possibility

We’ve had some very light flurries early this morning, after sunrise, and again this afternoon.  Still, nothing to show for the effort.  But, this evening’s clipper may give us at least a dusting.

The weak clipper has be producing very light snow across southwestern Indiana this afternoon and is moving eastward.  It’s also weakening.  Very little snow (if any) will drop south of I-64 tonight, so this system will be mostly north of Louisville.  We’ll probably see some flurries twice this evening – centered around 6 and 11 P.M.  No more than a dusting is expected anywhere near Louisville.  Low tonight in the upper 20’s and not much increase tomorrow with highs about the mid 30’s.

Monday into Tuesday

For the past several  posts, I’ve been pointing toward a strong Alberta Clipper expected to move into the western Great Lakes early next week.  Models are now projecting the primary snow chance for us Monday evening.  South of Clipper Monday, we’ll see see strong southwesterly winds and a quick warming into the 40’s.  The cold front trailing the clipper will push across central IN/KY Monday evening.  That will bring us the coldest air mass of the season Tuesday through Thursday.  Temperatures should drop to the lower single digits a couple of days.

What about snow?

Yesterday I mentioned the (to me) unusually high amount of precipitation the GFS was projecting with that front.  The weather south of clippers is usually quite dry.  Today, the GFS forecast reduces the rain/snow totals considerably.  The NAM is also low.  That seems much more reasonable to me.  But, it also reduces the snow potential to less than an inch.  It’s early, things could change.
