Active Wintry Week Ahead…

Busy Winter Pattern…Frigid air is helping usher in the new week and this morning’s snow bursts are setting the tone for potentially “more important” snow events in the days to come.

First things first though and that’s today.  Morning snow showers and heavier squalls will diminish and give way to an absolutely bitter feel for the afternoon.  Highs today took place at midnight and will continue to plummet through the day.  We’ll be in the single digits by dinner.  Wind chill values tonight and Monday will reach 20 degrees below zero.  Ouch!

All eyes will then shift to an approaching mid week snow maker and this should be a “plowable” event for most.  We expect a swath of snow to roll through central IN late Tuesday night into Wednesday morning.

Just as soon as the mid week snow maker moves out, we’ll have to turn our attention to late week.  There are many questions regarding the northward extent of snow with this storm, but the overall set-up from this distance has to put a smile on the faces of Ohio Valley snow lovers.  The blocking high to the north will be sufficient to supply cold air at the surface as moisture is supplied from the Gulf of Mexico, but it will limit how far north the low will track.  Is this an Ohio Valley or TN Valley event?  Ensemble data at the moment leads us to believe this will track far enough north to impact our region.  We’ll have to sort through additional details in the coming days.

Bitter Week Ahead; What About Snow Chances?

January to date is running 2 degrees above normal at IND.  That number will drop significantly this week with the punch of arctic air inbound.

After a snowy week last week, we’ll attempt to make another run this week.  Despite model inconsistencies, we focus on Sunday morning, Tuesday night-Wednesday morning, and late week for accumulating snow prospects.  More on that in a minute.

Note the difference in snow cover, locally, when compared to this time last year.  Can we get things to look similar to image 2 below come late week?  We’re on the playing field, at the very least.

A blast of snow showers and embedded squalls will accompany the arctic surge Sunday morning and may accumulate up to an inch in spots.  Strong and gusty winds will create brief whiteout conditions from time to time.

Things remain very active moving forward.  While the model specifics differ significantly at this juncture (no surprise ;-)), it’s important to look at the overall picture and see the potential of a fairly widespread winter event late next week.f144ps2png-atls13-95e2cf679cd58ee9b4db4dd119a05a8d-AYqVLj

Stay tuned.  There are significant differences between the potential of this event and the reality of the past several more significant precipitation makers.  – Namely a blocking cold high to the north as the more significant moisture arrives.  This will help supply the cold and limit the northward track to a point.  Is it a mostly snow event or do we get into the wintry mix potential?   Many questions will have to be answered in the days ahead.
