Tuesday Evening: Cold Pattern…

Quick couple updates this evening:

Virtually all of today’s model data has jumped on a stronger storm system for the weekend as opposed to a flatter wave.  This leads to a more northwest track and would imply more “wet than white” for local precipitation types for the weekend.  One important difference between this upcoming event and those of recent past is that arctic air is now on the playing field and this can create all sorts of “havoc” in mid range modeling.  We’ll keep a close eye on things.

The other HUGE item of business we want to get across is the prolonged and rather impressive cold pattern.  A series of arctic highs will come down the Plains and spread southeast the upcoming 7-10 days.  Despite a potential brief spike in temperatures Saturday, it’s a MUCH colder than normal pattern.  Eventually, we’ll have to closely monitor the potential of a couple of snow-producing clipper systems.  Sometimes these can be overachievers, depending on track and intensity and one of two clippers next week may be just that…

More later!  Have a great evening!

Fresh Arctic Air…Arctic air is on the move this morning and will result in a bitterly cold close to 2014.  This arctic air may be accompanied by a snow flurry or scattered snow shower later this afternoon (especially across northeast and east-central Indiana).  The bigger story will be the bitter feel to the air as wind chills fall to around zero tonight and Wednesday morning.

Dry, but frigid conditions remain New Year’s Eve and New Year’s Day.  If you plan on ringing 2015 in downtown Wednesday night, be sure to be prepared for the cold and dress warmly!

Weekend Storm System…We continue to track a storm system for the weekend, but more questions than answers remain on precise track and timing and will have a huge impact on precipitation types and amounts.  For now we forecast a wintry “potpourri” of rain, sleet, and snow Friday night into Saturday, tapering to backlash flurries Sunday.  Stay tuned.

Eyes On Clippers…Indications are that we may get into a rather busy clipper pattern next week.  The first of possibly two clippers may deliver snow Monday night into Tuesday.  Cold weather continues.
