Forecast Updated 02.12.14 @ 7:50a

Midweek Moderation…While still cold (and still below normal), temperatures will begin to moderate from the frigid readings of the past few days. Additionally, we’ll continue to enjoy sunny skies both today and Thursday, though we’ll add a gusty southwest breeze into the mix Thursday.

Accumulating Late Week Snow…We’re eyeing two fast moving clipper systems that will deliver accumulating snow for late week. The first snow event moves in Friday followed by a second snow maker Saturday. Both have the potential to produce a couple inches of snow across the region and we’ll be able to fine tune these amounts over the next day, or so.

Rainy And Milder…A push of milder air will move in early next week. Unfortunately, the milder air will come at a cost. With the heavy snow pack on the ground combined with the warmer air moving in from the southwest we’ll be looking at a gloomy period, including a couple waves of rain.

A push of colder air will swoosh back in here Tuesday night and could lead to a wintry mix before precipitation end. Looking longer term, we’re still expecting a “taste of spring” late next week!

Bitterly Cold Start…Take a look at the 8a central Indiana weather roundup, courtesy of the National Weather Service:

INZ030>032-037>040-046>048-054>057-064-065-111400-
CENTRAL INDIANA

CITY           SKY/WX    TMP DP  RH WIND       PRES   REMARKS
INDIANAPOLIS   MOCLDY    -4 -10  75 N3        30.46R

KOKOMO *+      PTCLDY   -20 -26  76 CALM      30.46R
MARION +       MOCLDY   N/A N/A N/A CALM      30.47S
MT COMFORT *+  PTCLDY   -17 -20  83 CALM      30.46R
SHELBYVILLE    PTCLDY    -9 -15  75 CALM      30.47R
ZIONSVILLE +   PTCLDY   -15 -22  71 CALM      30.46R

This just makes me shiver! We note temperatures as low as 16 degrees below zero reported at Zionsville this morning just after 7 o’clock. Today will be another brutally cold day, but sunshine will prevail. Arctic high pressure will remain anchored over our region and result in another bitterly cold night tonight, but not as cold as it was last night/ this morning.

Midweek Moderation…We’ll begin to get into a westerly and southwesterly air flow Wednesday into Thursday in advance of our next snow maker. While temperatures will remain below average levels, it’ll feel nice to go above freezing Thursday, albeit briefly. Gusty southwest winds could offset the relatively milder feel Thursday, as gusts may approach 25-30 MPH by afternoon.

Meanwhile, a major winter storm will impact the Deep South and result in heavy snow and ice accumulations. My old stomping ground of Johnson County, TN will likely accumulate 7-10″ of heavy, wet snow Wednesday into Thursday morning.

Tracking Two Snow Systems…We continue to have a couple questions around two snow makers Friday and Saturday. The Canadian forecast model remains most aggressive in snow production, delivering a full-blown snow storm Friday with 4-6″ totals while the GFS suggests we struggle to accumulate 1″ Friday. We’re continuing to go with a blend between the two, and side with the European model for now. This would suggest 1-2″ of snow Friday followed by another fast moving clipper system Saturday that could deposit another 1″, or so. Stay tuned as we continue to fine tune the Friday-Saturday forecast.

Milder Air, But Wet…Our next storm system will move in Monday and looks to primarily be a rain maker. Who thought highs approaching 40 (seasonal levels) would feel warm?! After this brutally cold winter, it’ll feel just that!

ANOTHER Bitterly Cold Air Mass

Forecast Updated: 02.10.14 @ 5:05p

Bitterly Cold Air To Begin The New Work Week…A fresh batch of bitterly cold air settled into the Hoosier state overnight and is ready to greet us “smack dab in the face” on the way out the door. We call this “ouch cold.” Additionally, winds will remain gusty this morning and result in wind chill values as cold as 20-30 degrees below zero Monday. Normally, this would be a huge deal, but seems to be “just another day” during the snowy and bitterly cold winter of 2013-2014.

As the arctic high moves overhead tonight into Tuesday morning, we’ll experience the coldest air of the week, bottoming out anywhere from 7 to 14 degrees below zero across the snowy central Indiana landscape. Officially, we’re forecasting 9 below to begin the day Tuesday for Indianapolis.

Midweek Moderation…Though we’ll remain below seasonal levels straight through the forecast period, we’ll notice a moderating feel to the air mass by the middle of the week. The relatively milder air may be offset by strong and gusty winds blowing from the southwest Thursday in advance of our next weather maker. Some concern will be there for blowing and drifting snow of the existing snow pack Thursday for the open country.

Monitoring Late Week…Forecast models continue to suggest we’ll deal with our next winter weather maker towards late week, but we caution timing and the precise track of the low pressure system will have to be fine tuned as we go through the week. At this extremely early stage in the game, it does appear as if an accumulating snow will occur with this system in the Friday-Saturday time period. Stay tuned.

Forecast Updated 02.08.14 @ 8:49a

Weekend Snow…While we’re not looking at a significant storm system this weekend, we’ll deal with waves of accumulating snow through the period. A period of light snow will continue today, especially through early afternoon and then we’ll note renewed snow developing to our west this evening. This area of snow is in response to additional upper level energy moving off the Rockies and will slide into central Indiana late tonight into Sunday. Finally, there’s the chance portions of central and south-central Indiana see a third wave of light snow Sunday night into early Monday morning. By the time all is said and done, we’re anticipating 1.5″ to 2″ of snow this weekend for most, with a few 3″ reports where snow persists. It’ll be a cold weekend, but nothing as bitter as the past few days have been.

Another Arctic Blast…A sprawling arctic high will settle into the Ohio Valley to open the work week. This will supply dry weather, but yet another bitterly cold air mass. We’ll note below zero overnight lows and highs only in the teens under mostly clear conditions.

Some Questions Around Late Week…Model data is in disagreement with the handling of the southern and northern streams of the jet late next week. As of now, we’re siding with a “middle of the road” approach and introducing snow showers into your forecast Thursday into Friday. The possibilities range anywhere from an accumulating snow event to dry skies with moderating temperatures. Stay tuned.

Bitterly Cold And Snowy Pattern Rolls Along…

Forecast Updated: 02.07.14 @ 8:07a

Frigid Close To The Work Week…Arctic high pressure will be centered over the Ohio Valley as we close out the work week. While this will lead to a mostly sunny sky, downright frigid conditions can be expected. The day will dawn with temperatures solidly below zero and include wind chill values as cold as 30 degrees below- a painfully cold start to the day, needless to say.

Watching A Weekend Snow Maker…We continue to keep a close eye on the weekend as another round of accumulating snow waits on deck. Questions remain as to just how much snow accumulates and while model data continues to suggest we’re only looking at a light, 1-3″, weekend snow event at the moment, the chance is still there that modeling begins to trend a little more “robust” with upper level energy as it crosses the Ohio Valley. High snow ratios will be at play here, meaning we’ll squeeze out more than the usual 1″ of snow for every 10th of an inch of liquid. We bracket Saturday afternoon into Sunday morning as the best chance of accumulating snow, but note this timing could change as we move through the next 24 hours. Stay tuned.

Weekend Snow Bookended By A Bitter Feel…A fresh blast of bitterly cold air will pour into the Ohio Valley and Mid West region to kick off the new work week. Temperatures will average more than 20 degrees colder than seasonal levels to begin the new work week and feature at least one, if not two, night(s) below zero. The brutally cold, snowy winter of 2013-2014 just keeps on keeping on…

Watching The Southern Stream…Model data is really struggling in the longer term and it has to do with how each respected model set handles energy in the southern and northern branch of the jet stream. We’re taking a “middle of the line” approach for now, including chances of snow the middle of next week.
