Thursday Morning Rambles…

A wintry mix of sleet and freezing rain continues to advance slowly northeast this morning. Thankfully, most of the rush hour should be over by the time any of this wintry precipitation arrives and we have a couple things going for us this morning: 1.) Drier air is giving this precipitation a tough time advancing northeast and 2.) by the time the precipitation arrives, temperatures will be marginal for many road problems, if any.  By far the more concerning issues are off to the southwest of Indianapolis, including places like Terre Haute (where moderate snow was reported at 9am).

The HRRR slowly pushes the wintry mix along the I-70 corridor this morning.

Attention then turns to a heavy rain event Friday into Saturday morning. Widespread 1-2″ amounts are expected.

Another Bout Of Rush Hour Wintry Mix; Longer Range Talk…

We think we’re dealing with another round of light freezing drizzle and a wintry mix for the Thursday morning commute.  Plan to allow extra travel time.

Forecast radar Thursday morning suggests freezing drizzle and a light wintry mix is in play across central Indiana.

There’s some longer term data that’s in stark contrast from what a positive PNA should produce (yet alone a strong positive PNA).  Typical positive PNA pattern should promote an eastern trough and associated colder than normal pattern as drawn below:

Needless to say, we disagree strongly with the NAEFS and GFS ensembles:

Regardless, the future will tell!

Changeable Monday; Note On Thanksgiving; Warm Open To December…

We wanted to touch on a few items of business this evening.  There’s a lot of weather going on this week…

Monday will feature drastic changes in the weather department across central Indiana:

  • Day starts mild and with lingering showers.
  • Strong and gusty winds will reach speeds of 45-50 MPH.  Batten down the hatches!
  • Temperatures crash late morning into the afternoon.  We start in the lower 50s, but fall to the freezing mark for the drive home across western parts of the state.  Eastern Indiana will see 32 degree air by 7-8 o’clock.
  • Scattered snow showers and flurries will fly across central Indiana Monday evening.

Thanksgiving Cold And Snow:

Temperatures will be much colder than average (low to mid 30s for highs and middle 20s for lows).  We’re still tracking a weak disturbance that could distribute light snow across central Indiana Thanksgiving Day.  Accumulations, if any, would fall in the dusting to less than 1″ range.

Opening December Warm:

We’ve been talking about how this exceptionally cold and wintry early season pattern would have to “relax” at some point and that appears to be the case as we open December.  The potential is there for well above normal warmth for the first week to ten days of December before we reload the pattern and introduce colder, more wintry times for mid and late month (anyone dreaming of a White Christmas)?
