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!

Watch For Slick Spots This Morning…A light wintry mix of freezing drizzle, snow, and sleet fell across central Indiana during the overnight.  Most roads have been treated, but still leave extra time to reach your destination and travel safely.  We think we’ll get rid of the low clouds, fog, and pesky light wintry precipitation during the afternoon and introduce at least a look or two of sun into your forecast!  It’ll be a chilly day as highs struggle to reach 40.

Tricky Thursday…Another fast moving disturbance will deliver light precipitation to central Indiana as early as Thursday morning.  With temperatures below freezing during the onset of precipitation, much of this may fall in the “frozen” or “freezing” form.  We’re concerned about light freezing rain and light sleet arriving during the morning commute Thursday and we’ll fine tune timing and precipitation type with tonight’s update.  Temperatures should slowly “warm” above freezing during the afternoon switching wintry precipitation over to just plain ole rain.  Stay tuned.

Wet Open To The Weekend…This morning’s model data is in much better agreement in regards to our wet weather maker slated for the opening to the weekend.  A slug of widespread moderate to heavy rain will push in here Friday and continue into early Saturday.  We think the back half of Saturday will feature drier air moving into the region which will set up a dry, but cold Sunday.

Cold Push Early Next Week…We’re siding with the colder solution early next week for now.  We forecast a cold front to blow through the area Monday afternoon with a quick shower possible (not a big deal).  Tuesday will feature colder northwest breezes and a scattered snow shower, or two.

Upcoming 7-Day Precipitation Forecast:

  • 7-Day Rainfall Forecast: 1.00″ – 1.50″
  • 7-Day Snowfall Forecast: Dusting to less than 1″

Milder Air, But Rain Chances Increase…Many will welcome a milder southwesterly air flow this weekend.  While this will serve to help give temperatures a significant boost from what we’ve dealt with practically the whole month of November, it’ll also provide increasingly cloudy skies and the chance of sprinkles/ light rain showers by afternoon and evening.

Sunday will be even milder as highs reach towards the 60 degree mark.  A cold front will approach the area Sunday afternoon and evening and provide a better chance of showers and colder air to open the new work week.

Have The Dramamine Handy…We’re in the beginning stages of a pattern change that’ll promote at least “attempts” of milder air in the coming 7-10 days.  That said, cold highs will remain across the northern tier and present challenges in both the temperature forecast, but also precipitation timing in the back half of this forecast period.  In the longer term we want to be very clear that signals suggest mid and late December feature a cold and wintry pattern returning.

As we move into the mid and late week stretch plan for possible changes.  There are challenges that abound, but for now our best meteorological take will feature increasing clouds Wednesday with light showers arriving by evening.  This would be followed by steadier rains Thursday before drier and colder air returns to wrap up the work week.  Stay tuned; it’s a tough pattern, as is usually the case during the transitional seasons.

News And Notes: Bill will be on WIBC with Ray Steele this morning around 7:30.  Be sure and tune in to hear a little weather chit-chat and a lot of talk about tonight’s Iron Bowl… War Eagle!

Upcoming 7-Day Precipitation Forecast:

  • 7-Day Rainfall Forecast: 0.50″ – 1″
  • 7-Day Snowfall Forecast: 0.00″
