Monitoring Severe Potential Tuesday Night…

We have scattered showers and embedded thunderstorms to deal with today and Monday (along with plenty of dry time, too), but our attention is beginning to shift to the potential of strong to severe thunderstorms Tuesday- particularly Tuesday night.

The SPC has outlined most of the state for a *Slight Risk* of severe thunderstorms Tuesday.

We note surface dew points surge into the upper 50s and lower 60s Tuesday.

SfcDPThis should be sufficient enough to help fuel a developing thunderstorm cluster in IL Tuesday afternoon/ evening that will likely race eastward with time Tuesday night.  We note a strong area of low pressure over the upper Mid West that will “bull-whip” a cold front through the region Tuesday night.  This will tap into the available moisture and relative warmth (lower to middle 70s a good bet for highs Tuesday) to continue the storm threat through IN and into western OH during the late evening/ overnight.

3All modes of severe weather appear to be in play right now, but we’re particularly concerned about the potential of damaging straight line winds within any thunderstorm complex that develops Tuesday afternoon/ evening.  We’ll also have to monitor the potential of discrete cells that develop away from the primary storm complex.

We turn cooler and windy Wednesday.

Stormy Evening…

  • Strong to severe storms this evening
  • Rain and snow showers Wednesday
  • Dry and chilly to wrap up the work week
  • Nice weekend ahead
  • MUCH colder next week

Stormy Evening…Tuesday is dawning nice and quiet with dry and chilly conditions in place.  A bit of fog has been reported just west and north of the city.  The quiet times will give way to a bumpy ride by this evening as a warm front passes, allowing a strong SW breeze to boost temperatures close to 60 (after dark high).

Scattered showers will develop this afternoon, but it’s the evening hours that we bracket (between 4-10p west to east) for the potential of strong to severe storms.  Some of these storms will be capable of damaging winds, and even a quick spin-up tornado can’t be ruled out.  Have a way to get the latest weather information this evening.

We turn cooler Wednesday with lingering moisture falling in the form of mixed rain and snow showers.  This won’t be a big deal.

Dry times will be with us to end the week and rumble into the Super Bowl weekend, with moderating temperatures.  The moderating trend won’t last long as models continue to suggest an arctic blast looms next week.  To go along with that cold, snow chances will also come.

Strong To Severe Storms Tuesday PM…

  • Morning fog in spots
  • Strong Tuesday storms
  • Mid week snow showers
  • Quiet end to the week

Strong To Severe Storms Tuesday Afternoon-Evening…Today is a day in between storm systems. We’ll deal with morning fog in spots (some freezing fog is being reported north and northwest of Indy this morning) and mostly cloudy skies.  It’ll be colder when compared to the weekend, but still warmer than average.

All eyes for this forecast package remain locked on Tuesday.  It’s still shaping up to be an active day, with strong to severe thunderstorms likely.  We bracket 3p-11p for the most likely time frame of thunderstorms across central IN.  Damaging straight line winds are of greatest concern, but caution a few embedded cells will be capable of producing a tornado.

Things turn much colder Wednesday and with lingering moisture, a few snow showers will be a good bet.

We turn much quieter to wrap up the week and head into Super Bowl Sunday.
