Busy, Busy, Busy…

Highlights:

  • Messy wintry mix arrives tonight
  • Briefly milder midweek
  • Potential storm brewing Friday

Snow And Ice Arrive Tonight…Clouds will lower and thicken across the state as we progress through the day.  We’ll also note a stiff easterly breeze as an approaching storm system inches ever so much closer.  This storm system will spread a wintry mix through the state tonight into early Monday morning.  Initially, we think most of central Indiana will deal with snow before a transition to freezing rain during the overnight, continuing into Monday morning.  Before the transition, 1″ to 2″ of snow seems to be the best idea before an icy glaze develops atop the freshly fallen snow.  Based on the expected transition to freezing rain, there’s an opportunity for up to a tenth of an inch of freezing rain.  That said, we’ll have to keep a very close eye on temperature profiles this evening as even the difference of a couple of degrees aloft can make all the difference in a faster or slower transition to freezing rain.  Expect the Monday morning commute to be heavily impacted.

Colder air will push back in here Monday evening into Tuesday with considerable cloudiness remaining.  A milder southerly flow will overtake the region Wednesday into Thursday.  Low clouds and fog along with drizzle will develop Wednesday and we may have to deal with a touch of freezing drizzle early in the day before temperatures rise.  A spike in temperatures will take place Thursday, briefly sending central Indiana into the 50s before a cold front slides through the state Thursday evening.

An area of low pressure will develop along the southern end of the frontal boundary and lift northeast into the TN Valley and eastern Ohio Valley Friday.  As colder air presses into the region, precipitation will change from a wintry mix of sleet and freezing rain to all snow through the day Friday.  It’s far too early to get specifics around accumulation ideas, but this storm has potential to be significant.  Much colder air will whip in here next weekend.

Frigid Saturday Gives Way To A Messy Sunday Evening…

Highlights:

  • Bitter cold eases
  • Mix of snow and ice
  • Milder midweek

Bitter Today; Wintry Mix By Sunday Evening…Most central Indiana reporting sites are checking in this morning between 6° and 10° below zero, but we note a couple of spots are even colder.  Arctic high pressure will remain in control of our weather today, leading to sunny and bitter conditions.

An approaching storm system Sunday will help increase our cloud cover through the morning and we expect snow to develop by evening.  As warmer air aloft works into the region, a transition to freezing rain is expected during the overnight into early Monday morning.  The morning commute looks very messy Monday.

Moderating temperatures will develop by midweek and as the milder air moves over the cold surface, thick fog and areas of drizzle and light rain will develop Wednesday.  A cold front will sweep through the state Thursday with showers and we’re keeping close tabs on a secondary piece of energy that will lead to a wintry close to the work week for portions of the Ohio Valley.  In fact, a significant winter event should develop out of this pattern Friday into Saturday.  The early call for now is that this is east of our region, but stay tuned.  Snow showers will fly in the colder air to close the week regardless.

Friday Morning Rambles…

I. Bitter Cold: We’re adding another morning below zero to an already impressive (and growing) list of frigid lows this winter.  Take a look at these morning lows in the…

Welcome Back Winter!

Highlights:

  • Mild open to winter
  • Christmas weekend snow
  • Cold returns

Pleasant Open To Winter…It’s a state divided today as clouds dominate across northern portions while the majority of central and southern IN will enjoy plenty of Vitamin D!  It’ll also be unseasonably mild today and Friday as a southerly air flow returns in advance of an approaching cold front.  That cold front will deliver spotty showers Friday and an area of low pressure will track along the boundary Saturday.  This will result in more widespread rain overspreading the region Friday night into the day Saturday. As colder air begins to filter into the region, we’re still thinking a narrow band of wet snow will develop along the northern shield of precipitation Saturday morning.

Turning our attention to Christmas Eve shows upper level energy moving across the Ohio Valley and this will likely result in an expanding area of snow across the region.  If trends continue, we’ll have to bust out the first snowfall map of the season Friday morning.  Are you dreaming of a White Christmas?

A cold pattern will engulf the region next week and we’ll await the middle and latter portions of the week for the potential of additional wintry mischief.  From this distance, it appears this very well may be a significant event.

Mild Air On Borrowed Time; Turning Wintry…

Highlights:

  • Dry midweek
  • Rain changes to snow
  • Turning bitter

Changes Await…The midweek stretch will feature dry and unseasonably mild conditions.  A storm system will deluge the Tennessee Valley today, but will be too far south to impact our weather.  We’ll shift our air flow around from the northeast today to more of a southerly direction Thursday afternoon.  This is in advance of our next storm system that will deliver showers as we wrap up the last work week before Christmas.

While confidence is beginning to increase in the evolution of things as we head into Christmas weekend, important details are still a bit “iffy” and will require additional fine tuning over the next day, or so.  With that disclaimer, here’s how we see things playing out:

A cold front will slip southeast Friday night and a surface low will move northeast along the boundary Saturday.  The general consensus this morning is that this wave of low pressure will track further southeast when compared to yesterday’s data.  This would yield a colder solution, locally, and subsequent faster changeover to a period of wet snow Saturday.  In fact, if trends continue, we may have to bust out the first snowfall map of the season for Saturday.  Hope for a White Christmas is very much alive and kicking.

MUCH colder air will drill southeast Christmas Eve and with enough upper level energy in place, we forecast an additional period of snow and snow showers Christmas Eve.  Bitterly cold temperatures will take control for Christmas and into early next week.
