Looking Ahead To Christmas Week: Quiet; Warmer Than Average…

It’s been a whirlwind of a few days around these parts, but, thankfully for those with Christmas travel plans, that’s all about to change- at least from a weather stand point.

A cold front will sweep through the state Wednesday morning and we’ll get a glancing blow of arctic air midweek.

The brunt of the arctic air midweek will be aimed at the Northeast, but central Indiana will feel a glancing blow.

This, combined with a fresh snowpack, will result in many neighborhoods waking up Thursday morning to 10s, and a few single digit reports.

With us being on the “outer fringe” of this arctic airmass, we’ll quickly moderate back to “normal” mid-December cold late week and into the weekend. This will be a harbinger of things to come as Christmas week, itself, kicks off.

Note the expanding upper ridge from the Plains into the Ohio Valley and Great Lakes region.

This will do a couple of things: shove the energy that could have led to a weekend East Coast storm south and result in an unusually quiet and mild time of things, locally for the Christmas holiday.

In fact, with the exception of a couple light snow showers in association with Wednesday cold frontal passage, we’re talking about a precipitation-free stretch through Christmas Day. Not only will the active pattern come to an abrupt halt, but temperatures will begin to moderate to well above average levels by Christmas Eve and Christmas Day. Highs around the 50° mark are likely.

The next chance of meaningful precipitation just come just after Christmas and likely take the form of rain.

Client Brief: Heavy Snow Bands Return Into The Overnight…

Type: Impactful Wintry Weather

This evening’s mesoscale analysis reflects a blossoming area of snow across MO into IL that will move east across central Indiana during the overnight.

What: Accumulating snow; mixed wintry precipitation

When: This evening into Tuesday morning

Temperatures: Lower to middle 30s, falling into the middle 20s Tuesday morning

Wind: Northeast shifting to the northwest Tuesday morning

Blowing/ Drifting: Minimal

Pavement Impacts: Plowing and salting will be required.

Our ongoing snowfall forecast from last night remains unchanged. Please note these are storm total snowfall amounts by Tuesday morning.

“Round 2″ is underway and we actually believe the overall snow shield will become more expansive with time through the late evening and overnight hours. Within this growing snow shield, embedded banding is expected that will include moderate to heavy snowfall rates. This continues to look like an I-70 special with respect to heaviest totals (7″ to 11″ range for storm totals). On either side of that heaviest snow zone, 4″ to 7” can be expected. On the north side, this is due to lighter intensity of snow (both with Part 1 and Part 2) and mixing issues on the south side.

Snow will exit the city just before daybreak, and southeast Indiana between 8a and 9a. Winds will shift to the northwest and an overall colder day is expected Tuesday, but at least we won’t have to worry about additional snow once past daybreak.

Cold air reinforcements will blow into town Wednesday with a couple snow showers across east-central Indiana. The bigger deal will be the cold, including temperatures that will remain stuck in the middle 20s through the daytime hours. Add in a stiff breeze and wind chill values will be in the 10s.

Confidence: High

Next Update: Tuesday morning

Time For The Heavy Equipment: Localized Storm Totals Approach One Foot By The Time All Is Said And Done…

High resolution guidance started to show the snowier solutions earlier this evening and that trend has continued this evening. The consistency is great to see, but we also notice a couple of interesting elements “upstream” that will likely ultimately end up producing a memorable mid-December snow storm across central Indiana by the time all is said and done.

Before we talk specifics, here’s our updated snowfall forecast. Please note, this is expected total snowfall by daybreak Tuesday morning. We wouldn’t be shocked to hear of localized one foot amounts along the I-70 corridor.

Periods of heavy snow will come to an end during the overnight. We think by 3a to 4a, most of the snow from “round 1″ will be to our east and we’ll be left with clean up duties before a Monday morning rush that will likely still be heavily impacted. By the time the 1st round is finished, most of the I-70 corridor will be shoveling and plowing away 4″ to 6” of wet snow.

We’ll then get into the expected lull in the action through a good chunk of the daytime Monday. That said, curious eyes will be focused in on south-central MO mid-to-late morning as precipitation blossoms in response to a strengthening surface wave that will move northeast out of the Ark-la-tex and into the TN Valley tomorrow night.

Precipitation will expand in coverage and intensity yet again tomorrow morning to our southwest.

This will promote an expanding shield of moderate to heavy precipitation moving northeast and overspreading central Indiana by mid afternoon Monday. For us here across central Indiana, this will fall as snow.

Heavy snow will return to the I-70 corridor Monday afternoon.

If you don’t have to travel tomorrow, we’d recommend staying home and off the roads. While conditions will improve late morning into early afternoon, travel conditions will go downhill in significant fashion by 3p to 4p Monday across central Indiana- including the metro.

Periods of snow, heavy at times, will continue into the overnight before pushing off to the east before sunrise Tuesday. By that time, the heart of central Indiana will be cleaning up from a double digit and most memorable mid-December snow storm.

Periods of snow will continue into the overnight Monday.

We’ll be left with colder, but generally dry conditions Tuesday. Temperatures will remain below freezing through the day, but the majority of the region won’t be dealing with any additional snowfall after sunrise…

Gas up that snowblower! Next update will come early in the AM.

Heavy Snow Tonight: Timing Out “Part 2” Monday And Looking Closer At The Late Month Pattern…

Client Brief: Updated Snowfall Forecast; Conditions Go Downhill Quickly This Evening…

Type: Impactful Wintry Weather

Forecast radar 9p Sunday

What: Accumulating snow; mixed wintry precipitation

When: This evening and Monday afternoon – Tuesday morning

Temperatures: Lower to middle 30s, falling into the middle 20s Tuesday morning

Wind: East northeast 10 to 15 MPH, shifting to the northwest Monday night with gusts to 25 MPH

Blowing/ Drifting: Minimal

Pavement Impacts: Plowing and salting will be required.

Right out of the gate, let’s talk accumulation: While we don’t need to make significant changes to the snowfall forecast, we did “tighten” the 3″ to 6″ band up a bit and scaled the 1″ to 3″ zones closer into central Indiana on both the north and south sides. This continues to be a central Indiana event- at least as far as heaviest snowfall totals go.

This event will still come in 2 waves, but it now appears as if the initial surge of moisture this evening and tonight will feature the heaviest snowfall rates. Snow will overspread the region this evening (arriving into Indianapolis, itself, between 6p and 7p) and come down heavily at times through the overnight hours. Part 1 will end before daybreak, but the damage will have been done by that point and the morning commute will be significantly impacted as central Indiana digs out from 3″ to 5″ of wet snow.

We’ll get a break through the bulk of the daytime Monday, but precipitation will once again overspread the region from southwest to northeast Monday evening, continuing into the predawn hours Tuesday. This will take the form of snow across central Indiana with a wintry mix and/ or a cold rain across southern and southeastern Indiana. An additional coating to 1″ of snow is possible with this 2nd wave of moisture.

Finally, winds will shift to the northwest and drive colder air into the state Monday night behind the departing storm. Everyone (including southeastern Indiana) will be below freezing Tuesday morning with additional travel impacts likely.

Confidence: High

Next Update: This evening

Client Brief: Snow Storm Inbound Sunday Evening – Monday…

Type: Impactful Wintry Weather

What: Accumulating snow; mixed wintry precipitation

When: Sunday evening through Monday

Temperatures: Lower to middle 30s, falling into the lower to middle 20s Monday night

Wind: East 10 to 15 MPH, shifting to the north Monday night with gusts to 25 MPH

Blowing/ Drifting: Minimal

Pavement Impacts: Plowing and salting will be required.

Sunday will feature a thickening and lowering cloud deck through the afternoon hours and this foretells what’s to come by evening. An expanding area of snow will overspread southern Indiana early evening and push into central/ north-central Indiana by mid-to-late evening, continuing into Sunday night. This will be the 1st of 2 rounds of wintry precipitation that will likely result in “plowable” accumulations for a good chunk of central Indiana come Monday evening. There will likely be a “lull” in the wintry precipitation Monday morning, but we anticipate widespread wintry precipitation to return late morning through the afternoon and into the evening hours Monday. In and around Indianapolis and points north, this 2nd round of precipitation should also primarily take the form of snow, but we think southern Indiana will have a period of sleet and potentially a cold rain across far southern Indiana before transitioning back to snow before ending. Because of this, we think southern Indiana will fall into the 1″ to 3″ range for storm totals. Much colder air will pour into the state Monday evening as winds shift to the north/ northwest and gust up to 25 MPH. Snow will pull out of the state from west to east late Monday night. Due to the timing of this storm, big impacts are expected to the morning and evening rush hours Monday.

Confidence: High

Next Update: 2:30p Saturday
