“Less Harsh;” Weekend Rain…

Highlights:

  • Turning “less cold”
  • Weekend rain
  • Chilly early next week

Sunny And Not As Cold…The arctic high that delivered the bitterly cold conditions over the past few days is scooting off to the southeast.  This will put the state under a milder (all relative :-)) southwesterly flow and temperatures will become “less harsh” as we wrap up the work week!

An approaching storm system will lead to increasing clouds during the afternoon and evening Saturday and drizzle will follow Sunday morning.  As the cold front draws closer, steadier rains will arrive Sunday night into Monday.  Colder times will sweep in behind the front and allow left over precipitation to end as snow showers Monday (not a big deal).

Tuesday and Wednesday will feature dry and chilly conditions.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall:  Dusting
  • Rainfall:  0.25″ to 0.75″

Frigid Air Relaxes; What Awaits?

2018 has opened on an absolutely frigid note.  Indianapolis is running an amazing 11° below average through mid-month.

Eight mornings so far this winter have plunged below zero.  We’ll see if we can add another to that list this morning (IND is officially at 0° as we write this).

52% of the country is covered in snow.  In fact, my old stomping grounds of Auburn, AL received 3″ of the white stuff overnight!

If you’re sick and tired of the cold, wintry conditions relief is on the way.  We’ll turn “less cold” through late-week and above normal over the weekend (around 40° Saturday and into the upper 40s Sunday).

A storm system will cut into the ridge Sunday with showers (image 1) followed by “backlash” snow showers and gusty winds Monday (image 2).

Thereafter, models see another storm that will approach the region late next week.  Since cold air won’t be readily available, it’ll take the perfect track to get impactful wintry conditions from this next event.  We’ll monitor things closely next week.  With this near Day 10, models will continue to struggle with timing, track, and intensity over the next few days.

As a whole, the second half of January should run milder than average.  However, as we all know, that doesn’t mean we won’t have wintry challenges to deal with.  The upcoming (10) days illustrates that nicely.  Looking ahead, we note the MJO is forecast to rumble through the warmer phases (especially if you’re reading this from the eastern regions of the country- where we expect warmth to be most anomalous into early February).

Other teleconnections also support a relaxation of the cold, and warmer times, overall, with the exception of the Arctic Oscillation which remains negative through the period.

It should be noted that the longer range data and overall trends, supported by our analogs, suggest winter roars back with authority as we get into February.  In fact, winter might not be so quick to leave this year either.  Data paints a cold, wintry open to meteorological spring this year, but we’re getting way ahead of ourselves.  It is only mid-January, after all.  🙂

Frigid Times; Moderating This Weekend…

Highlights:

  • Dangerously cold
  • Dry times return
  • Moderating this weekend

Bitter, Bitter…Arctic high pressure will dominate our weather through the early and mid week stretch.  We note high resolution modeling trying to swing a couple bands of light lake effect snow through north-central Indiana later this afternoon and evening and we’ll continue to keep snow showers in our forecast for this reason.  Otherwise, cold is the story today.  We’re starting our Tuesday adding yet another sub-zero low to the already impressive list this winter.  Cold continues Wednesday before beginning to turn “less cold” through late week.

Our next storm system will approach this weekend.  As low pressure tracks into the Great Lakes, a milder southwesterly flow will allow temperatures to zoom all the way up close to 50° by Sunday.  Fog and drizzle will develop Saturday before “showery” and breezy conditions build in ahead of the front Sunday.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall:  Dusting
  • Rainfall: 0.40″ to 0.50″

Monday Morning Notes…

Bursts of moderate to heavy snow will work across the metro during the next couple hours. This will lead to significant drops in visibility and serve to mess up roadways even more than they currently are. If you don’t have to travel through the morning hours we recommend staying home and allowing road crews time to get things cleaned up.

Most of the steady accumulating snow will be over with by late morning and we’ll just be left with scattered snow showers through the afternoon hours. Perhaps the bigger story by then will be significant blowing and drifting snow as gusty westerly winds help usher in colder air. If your travels include country roads, or north-south oriented highways, plan on considerable blowing and drifting snow this afternoon and evening.

We have no changes to our going snowfall forecast with this system.

Finally, as the arctic front sweeps through the state this afternoon, it’ll likely kick up some intense, blinding snow bursts.  While these won’t last long, they’ll blast through during the evening rush and will serve to dramatically lower visibility.  We note high resolution models are picking up on these snow bursts on forecast radar products.

We’re left tonight with bitterly cold conditions that will continue to grip the region through midweek. Most of us Tuesday morning will be below zero. A moderating trend will develop by late week, continuing through the weekend!
