Icy Morning…

Screen Shot 2015-03-03 at 7.58.16 AMRough Travel Conditions This Morning…Freezing rain and freezing drizzle is making a mess of the morning commute.  Thankfully, eventually we’ll climb above freezing around, or just after, noon.  Before then, icy travel conditions can be expected.  Take it slow or postpone travel until the afternoon if possible.  By this afternoon, temperatures will climb above freezing and plain ole rain can be expected into tonight.  We don’t anticipate flooding issues locally as rain won’t be heavy enough and temperatures won’t be warm enough to result in significant melting.

Much colder air will blow into town late tonight and Wednesday morning and as a second area of low pressure tracks along the front, widespread accumulating snow is a good bet across the southern half of the state Wednesday afternoon into Thursday morning.  As of now, we still target areas along and south of I-70 most at risk for snow accumulation Wednesday afternoon.

A much drier, but cold, pattern will be with us to wrap up the work week, including more record cold a good bet.  Dry and slightly milder conditions are ahead over the weekend before a weak system may deliver a light snow or rain shower early next week.

Looking ahead, it appears as if we finally may deal with a much milder, spring-like pattern around mid March.  60s for highs anyone?!  That said, concerns remain that we reverse this and go colder than normal late March.

Upcoming 7-Day Precipitation Forecast:

  • 7-Day Snowfall Forecast: 1″ – 3″ (south)
  • 7-Day Rainfall Forecast: 0.50″

A Lot To Discuss…

Good evening, friends!  As promised, there’s a lot on the weather menu over the course of the upcoming several days.  Let’s get right into the details.

The National Weather Service has issued a Winter Weather Advisory from 3a-12p for all of the region to account for the sleet and freezing rain situation we’ll deal with late tonight into the first half of Tuesday.  We still expect significant travel issues and overall impacts to the Tuesday morning commute.

Forecast radar shows freezing rain spreading into the region between 3 and 4am.

1Light freezing rain and freezing drizzle will continue for the better part of the morning hours as temperatures likely won’t climb above freezing until early Tuesday afternoon, especially from Indianapolis and points northeast.

Forecast temperatures at 12p Tuesday.

hires_t2m_indy_24We still don’t anticipate many big time flooding concerns as a.) temperatures won’t warm all that much (we MAY reach 40 Tuesday evening, but that’s a big question mark) and b.) most of the heavy rain will remain south of central Indiana.

Here’s expected liquid-equivalent totals through Wednesday morning.

2The next concern is the threat of accumulating snow for central and southern portions of the state Wednesday afternoon through Thursday morning. Arctic high pressure will limit the northern extent of significant precipitation, but, as mentioned previously, energy rounding the base of the trough will ignite another wave of low pressure to move along the pressing arctic front.  As of now, we target areas along and south of the I-70 corridor most under the gun for a potentially impactful snow storm Wednesday afternoon into early Thursday morning.

3The individual GFS ensemble members have also been trending north and overall more excited about snow prospects, as well.

7The other item on the agenda is a shot of record cold in here for late week.  Sub-zero lows are a good bet by Friday morning.  Highs Thursday will push for a new record low maximum temperature.

Icy Tuesday Morning…

We continue to be very concerned about the likelihood of an icing event across central Indiana late tonight into early Tuesday afternoon. A significant snowpack in place won’t allow temperatures…

More On This Week…

It was a record snowfall officially at IND where a storm total of 7.9″ was recorded (5.9″ accumulated since midnight). Many other 8″ type amounts are common throughout the heart of central Indiana- including right here at the IndyWx.com HQ.  Yours truly ventured out through the village of Zionsville this afternoon.  Simply beautiful!

We have a busy weather week upcoming and wanted to touch base on a few items of note:

1.) Freezing rain and potential slick travel will be possible very late Monday night into Tuesday morning.  Moisture will attack from the southwest and run into an impressive snowpack currently in place across central Indiana.  Despite warmer air moving in aloft, surface temperatures will remain cold enough through late Tuesday morning to allow precipitation to fall in the form of sleet and freezing rain Tuesday morning.  It appears as if enough freezing rain could accumulate to result in slick travel throughout the region.  While temperatures will “warm” into the lower 40s Tuesday afternoon, this is a far cry from the lower 50s modeling tried to suggest a few days ago.  Furthermore, cold air will quickly rush back in here Tuesday night into Wednesday morning.

2.) Accumulating snow threat for the southern half of the state Wednesday into Thursday. Additional “energy” will round the base of a digging trough over the southern and central Plains states Wednesday. This will help ignite a surface low along the front and temporarily lead to the front stalling out just to our south and east.  It’ll be close as to just how far north the accumulating snow shield makes it across southern and central Indiana, but will require  a close eye in the coming day or two.  We note some of our more reliable modeling placing central and southern portions of the state “under fire” for additional accumulating snow.

3.) Serious and potentially record cold returns this week.  Yet ANOTHER blast of bitterly cold air will plunge into the area Wednesday night into Thursday.  With snow on the ground, it’s possible this direct discharge of arctic air is even colder than what some data might suggest at this time.  As it is already, we think some central Hoosier neighborhoods deal with sub-zero air in the Thursday/ Friday morning time frame.  Thursday’s high will only manage to climb into the teens across the region.  (Keep in mind the average low is 28 and average high is 45).  Just amazing stuff!

Snow Storm Brewing Saturday Night-Sunday…
