Client Brief: Time To Gas Up The Snow Plows…

Type: Impactful Wintry Weather

A winter storm will impact the Ohio Valley through the 2nd half of the work week.

What: Accumulating snow and sleet

When: Wednesday afternoon through Thursday evening

Temperatures: Lower 30s falling into the 10s by Thursday evening

Wind: Southeast 10-15 MPH Wednesday afternoon shifting to the north Wednesday night and northwest Thursday. Winds will gust 20-30 MPH Thursday evening.

Blowing/ Drifting: Light to moderate by Thursday evening

Pavement Impacts: Salting and plowing will be required

A busy 48 hours awaits for central Indiana as a winter storm begins to impact the region. Mid and high level cloudiness will continue spreading over the region this evening and give way to a lowering and thickening cloud deck overnight and Wednesday morning. This is all thanks to a developing area of low pressure over the Ark-la-tex region. This surface low will track northeast into the TN Valley Wednesday and into the central Appalachians Wednesday night into Thursday morning. Long time residents of the Hoosier state know this is a favorable track for impactful wintry weather across these parts and this will be no exception.

Moisture will begin to lift northeast during the day Wednesday and reach the I-70 corridor around or just after lunchtime. Across the southern half of Indiana, this moisture should primarily fall in the form of a cold rain (perhaps a bit of sleet initially as the precipitation moves in). However, further north, trouble will ensue. The air won’t only be colder at the surface, but the depth of cold air will be much deeper. This will result in precipitation that should predominantly fall in the form of a sleet-snow “concoction” along and north of the I-70 corridor where we think an axis of 2″ to 4″ of snow/ sleet will accumulate with this storm- including Indianapolis. Further north, less sleet is anticipated and will result in heavier snowfall totals. The northern Indianapolis ‘burbs and points north to include Lafayette, Kokomo, Logansport, Ft. Wayne, and Muncie can expect 4″ to 6″ of snow with this storm system. Most of that will fall Wednesday afternoon into Wednesday night with additional lighter snowfall accumulation occurring with “wrap around” snow showers and embedded squalls Thursday afternoon into evening. (The Indiana Snowbelt (you know who you are :-)) can expect additional heavier snow accumulation, courtesy of lake effect).

A brief, but potent shot of arctic air will pour into the region Thursday afternoon and set us up for widespread single digits by Friday morning, including the threat of some sub-zero temperatures where the heaviest snowpack is laid down.

Confidence: High

Next Update: Wednesday morning

Burst Of Snow This Afternoon; Storms And “Rumors” Of Storms This Upcoming Week…

The day is starting off on a cold note with some fog and low clouds around, but at least we’re dry (for now). That will begin to change here in a few hours as a burst of snow moves into the city around lunchtime. A brief period of moderate to heavy snow may whiten the ground just north of the city before a transition to a cold rain for the better part of the afternoon.

Further north, cold air will hang on longer and a more significant period of snow is expected through the afternoon and early evening. In fact, periods of heavy snow can be expected, including snowfall rates up to 1″ per hour at times. If you have travel plans to places such as Ft. Wayne, South Bend, or Logansport, we’d recommend preparing for slick travel and snow covered roads can be expected. This will be a wet and heavy snow. Pavement impacts will require salting and plowing across the northern 1/3 of the state this afternoon into the evening.

Here’s our snowfall forecast today:

The attention will then shift to a period of moderate to heavy rain through the evening and into the overnight across the I-70 corridor. By the time all is said and done Monday morning, widespread 1″ to 1.5″ is expected with the passage of this storm system. Good news? Most of the rain should be south of our area by the morning rush Monday.

High pressure will then settle into the Ohio Valley as we move into Monday evening and Tuesday, allowing a briefly quieter period of weather to arrive on the scene.

By this time, however, all eyes will shift to the southwest and our next storm system that should be brewing. While models differ on the specifics with this storm, the overall upper pattern suggests we need to remain on our toes with respect for the potential of additional winter weather stretching from the mid-MS Valley Wednesday, Ohio Valley Wednesday night into Thursday, and interior Northeast Thursday into Thursday night. A brief, but potent shot of arctic air would follow to close the work week- especially if we can get some snow down.

Should snow get laid down with this system across the OHV region, a cold arctic high would be capable of sending temperatures into the single digits to close the work week.

Stay tuned…
