Pre-Christmas Weather Rambles…

I. While we certainly aren’t talking about significant weather events between now and Christmas Day, there will be a couple of impulses of upper level energy that may be just strong enough to produce snow showers and flurries at times.  We’re tracking (2) weak disturbances that stand a chance to get a couple of snow showers going Sunday evening and again Christmas Day.  The one on Christmas, itself, will be a bit stronger and may have a shield of more organized precipitation- likely that would start as wet snow before transitioning to rain before ending.

II. A much stronger storm system will wrap up to our northwest Wednesday night and Thursday.  We’ll notice an increasingly strong southerly breeze during this time period and rain will be on the increase as we progress through the day Thursday.  The trade-off?  Highs between 55° and 60° to close the week- though those temperatures may actually come Thursday evening before cooler air begins to slip in here during the day Friday.

As things stand now, both the GFS and European models, courtesy of Weathermodels.com, aren’t overly excited on rainfall amounts with this storm system, but I think they’ll trend wetter as time goes on.  We’ll continue to forecast amounts between 0.50″ and 1″.

III. All attention is squarely focused on a significant pattern change that takes shape as we head into the new year.  As mentioned in previous posts and discussions, the transition is likely to be a stormy one, but it’s far too early to talk precipitation types.  A combination of ingredients appears to be aligning to create a colder than normal (and potentially significantly so) pattern at the traditionally coldest time of year (mid-Jan).

In the more immediate term, we note the latest GEFS showcases a classic “horse shoe” block that will favor a wintry regime across the east to open the new year- thanks to Tropicaltidbits.com.

Cold And Quiet; Big Winter Storm To Our Southeast…

Highlights:

  • Prolonged stretch of cold, quiet weather
  • Major winter storm for the southern Appalachians
  • Next storm delivers rain late next week

Brrrrrrr…It’s another frigid early December morning across central Indiana, but there really isn’t any “exciting” weather to discuss through the early part of next week.  High pressure will supply quiet conditions through the daytime Wednesday.  We’ll notice some mid and high level cloudiness today from a winter storm that will drop historic snow amounts across the southern Appalachians tonight into Monday.  Otherwise, plentiful sunshine can be expected with slowly moderating temperatures into the new work week.

Clouds will lower and thicken Wednesday afternoon and light rain will likely arrive after dark.  Our next storm system will deliver rain and gusty winds in here late week.  Though we haven’t “taken the bait” just yet, there’s the chance of some wind-whipped wrap-around snow Friday.  We’ll give it another couple model runs before building that into the forecast…

Cold, But A Good Supply Of Vitamin D…

Highlights:

  • Frigid start
  • Prolonged stretch of sunny weather
  • Next storm holds off until mid to late next week

Bundle Up…“Number-busting” cold has settled into many Mid West communities this morning as just enough snow cover combined with clearing overnight skies.  The result is a 5º to as much as a 10º difference in actual low temperatures this morning when compared to the majority of guidance yesterday.  Bundle up, as many across central Indiana are waking up to temperatures in the upper single digits to middle 10s.  Thankfully, dry conditions are expected not only today, but straight through the weekend and on into early next week- along with plentiful sunshine!

Temperatures will gradually turn “less cold” early next week and we’re eyeing our next storm system for a Wednesday night to Thursday arrival.

Snow’s On The Lunchtime Menu; Cold, But Quiet Stretch Of Weather Ahead…

Highlights:

  • Snow arrives around lunchtime
  • Cold weekend ahead
  • Increasing sunshine

Messy Afternoon Commute For Some…The day is starting quiet, but a fast moving arctic cold front will push through the state this afternoon.  Ahead of the boundary, an expanding area of precipitation will break out late morning into the early afternoon hours.  From the city and points north, most of this should fall as wet snow.  South of the city, a mixture of rain and snow is expected.  A quick 1″ of snow is likely for areas north of Indianapolis and as temperatures fall this afternoon and evening, a slick evening commute is possible.  Allow yourself extra time.

Cold air will reinforce itself behind the front tonight and through the weekend, BUT sunshine will return!  All eyes will be off to our south as a major winter storm impacts our friends across the TN Valley into the Southern Appalachians.  If you’re one of our viewers from the east TN/ western NC mountains, get to the grocery store today and plan to hunker down.  You’ll need the yardstick to measure this one when all is said and done Monday night…
