  • Severe Weather Sunday; Much Colder Next Week…


    • Clouds more bark than bite today
    • Stormy setup Sunday
    • Trending colder next week

    All Eyes On Sunday…The cold front that passed through the region Thursday night and setup the gorgeous close to the work week is lifting back north this morning as a warm front.  This will result in overcast conditions today, areas of sprinkles or drizzle later in the day, and rising nighttime temperatures.  Scattered thunderstorms will develop across central Indiana late tonight with a warmer and increasingly moist environment.

    Sunday will certainly be a day to remain weather-aware.  The overall setup hasn’t changed from what was discussed yesterday with a warm and moist southwesterly air flow in place ahead of an approaching cold front and associated area of low pressure.  Additional ingredients in play suggest we need to monitor the threat of large hail, damaging straight line winds, and potentially tornadoes.  Individual storms (potential super cells) are expected to fire across central and northern portions of the state Sunday afternoon into early evening.  These will be capable of quickly pulsing to severe levels and include potential of large hail, as well as tornadoes (particularly in the vicinity of the warm front which is expected to be draped across north-central parts of the state).  Individual cells are anticipated to “morph” into a squall line Sunday evening, including potential of a quick spin-up tornado, as well as damaging straight line winds.  With a moisture-rich air mass in place (precipitable water values are expected to approach 2″ Sunday evening), locally heavy rainfall is also expected.

    All of our “excitement” will come to an end overnight Sunday and we’ll trend much colder (and calmer) during the new work week ahead.  Our next storm system will pass by to our south Tuesday, but may be close enough to spark a light shower across central portions of the state.  Drier and colder conditions build in later in the week.

    Upcoming 7-Day Precipitation Forecast:

    • Snowfall: 0.00″
    • Rainfall: 1.50″ – 2.50″

  • Latest Thoughts On Memorial Day And Race Weekend…

    As the race weekend and Memorial Day draw ever-closer, data is able to pick up on some of the specifics associated with our weather for the all-important long weekend.

    After scrolling through the data this evening, it appears as if we need to bracket late Friday night-Saturday morning and again late Saturday into Sunday morning for the potential of two rounds of gusty storms.  Some of these storms could reach strong to severe levels, and the Storm Prediction Center continues to outline central Indiana for a Slight Risk Saturday (large hail and damaging straight line winds are of greatest concern, locally).

    Despite having to dodge a couple rounds of gusty storms this weekend, we want to stress that the majority of the holiday weekend should feature rain-free hours, and certainly isn’t worth cancelling any outdoor plans.  In fact, after a beautiful Carb Day, most of the daytime hours both Saturday and Sunday should be rain and storm free.  Have a means of getting the latest weather information, but plan to enjoy long stretches of rain-free hours this weekend.

    Much more later!

  • Thursday Morning Rambles…

    1.)  Morning showers and thunderstorms continue to impact north-central Indiana this morning and given the look to downstream trends on radar and satellite, it would seem like it’s going to be tough to get into any sort of significant sunshine this afternoon. This is great news as it’ll limit severe potential.  That said, we still can’t rule out a severe thunderstorm this evening with large hail and damaging straight line winds of greatest concern.  The updated (9a eastern) outlook from the Storm Prediction Center continues the “enhanced risk” for the southern half of Indiana.

    2.)  We bracket the hours of 2p-8p (couple hours earlier from yesterday’s thinking) as the period of potential most widespread strong to severe thunderstorms across central Indiana, and the HRRR forecast radar shows what the radar may look like this evening. Have a means of getting the latest warnings.

    3.)  Scattered showers will continue into Friday morning before drier air arrives during the evening hours.

    4.)  This drier trend Friday PM is one that will continue into the weekend.  High pressure will supply mostly dry weather through the entire weekend (small shower chances return Sunday evening), including sunshine.

    5.)  Another active period of weather awaits next week, including multiple rain chances early and late week.  The latter storm looks to be the bigger event with heavy rain and thunderstorm potential Wednesday into Thursday.  7-day rain numbers check in between 1.5″-2″ with locally heavier amounts.

    6.)  The story becomes a chilly one next weekend, and models suggest central Indiana may be dealing with frost and freeze conditions by next Saturday or Sunday morning.

  • Timing Thursday Storms…

    Happy Wednesday!  Today’s sunshine sure was nice and I hope you had an opportunity to get outside and enjoy it.  Unfortunately, the pleasant weather won’t last as a storm system begins to impact central Indiana as early as the overnight period.  Clouds will continue to thicken tonight and showers and thunderstorms (non-severe) will arrive during the predawn hours.

    We note short-term, high resolution, forecast radar data brings the initial wave of thunderstorms through the city during the 2a-3a time frame early Thursday morning.

    Multiple rounds of showers and thunderstorms will likely impact central Indiana through the mid and late morning hours Thursday.

    As we press into the early afternoon hours, model data suggests we see a “lull” in the stormy weather and potentially even a few breaks in the cloud cover.  This would serve to “up the ante” in regards to the prospects of severe weather potential Thursday afternoon, particularly mid and late afternoon through the evening hours.  Accordingly, the Storm Prediction Center continues to highlight central Indiana for the risk of severe weather Thursday.

    In fact, given a look at the most recent data, I wouldn’t be surprised to see the “enhanced” risk area expand further north in future updates.  This would also include all modes of severe weather (large hail, damaging straight line winds, and potentially a tornado). As things stand this evening, we bracket the hours of 4p and 10p Thursday for the greatest potential of severe weather.

    Forecast radar paints a stormy picture Thursday evening and, as mentioned above, a few of these storms could become severe.

    As we push into the overnight hours Thursday into Friday, unsettled weather will continue, but we’ll get rid of the severe potential.  “Nuisance” type showers will continue into the first half of Friday before drier air arrives Friday afternoon and evening.  This drier theme will settle in for the weekend and provide a very pleasant open to April.

    Ensure you remain weather-aware Thursday and have a means of getting the latest warnings.

  • Bumpy Start To The Work Week…


    • Stormy open to the work week
    • Colder midweek
    • Storms return this weekend

    Couple Rounds Of Storms Possible Today…Radar this morning is showing widespread showers and thunderstorms sinking south out of northern Indiana.  Expect to get wet in, and around, the city as the rush hour gets into full swing.  We’ll monitor this evening for the potential of another round of thunderstorms that’ll, once again, originate across northern IN before tracking southeast.  We don’t anticipate widespread severe weather with these rounds of storms, but small hail is certainly possible in some of the storms.

    Tuesday will be an overall quieter day, but a cold front will pass with a shower chance Tuesday evening.  We’ll then note a northerly wind shift and a much colder air mass Tuesday night through Thursday morning.  Highs Wednesday will run 10°-15º below average.  If you’re not a fan of the cold, no need to fret as a warmer southerly flow will develop Thursday afternoon and put us in position to return to seasonable levels for highs Thursday after the chilly start.  We’ll then run much warmer than average this weekend, but it comes with a wet and stormy trade off.  Periods of heavy rain are possible Saturday into Sunday.

    Upcoming 7-Day Precipitation Forecast:

    • Snowfall: 0.00″
    • Rainfall: 1.25″ – 1.75″

  • Active Severe Weather Night Ahead…

    The updated outlook from the Storm Prediction Center shows an expanded “Enhanced Risk” to encompass all of central Indiana.

    This morning’s showers and thunderstorms were the first of (3) rounds of storms expected today.  Ironically, most of the daytime hours should be rain and storm-free.  We’ll note scattered showers and thunderstorms across northern portions of the state this afternoon, as a warm front continues to lift north.

    As we progress into the overnight hours tonight into Wednesday morning, that’s when we’re most concerned for potential severe weather impacts to central Indiana.  Short-term, high resolution, modeling continues to suggest individual storms (perhaps super cells) will develop around midnight across the region.  These would include all modes of severe weather, including the potential of large hail and a tornado.

    Finally, our severe weather threat will come to an end with the passage of a squall line during the pre-dawn hours Wednesday morning.  The biggest threat with this line of storms will be damaging wind, but a quick spin-up tornado can’t be ruled out either.

    With the majority of this event occurring when most are sleeping, please have a way to get the latest information on watches and warnings that are sure to come tonight.  We highly encourage everyone to have a weather radio, and be sure to set the alert mode to “on” before bedtime tonight.

    We’ll be back this evening with a fresh 7-day update!  Make it a great Tuesday!

  • Unseasonably Warm And Stormy Weather Gives Way To Late Week Chill…

    Monday evening is running much warmer than this time Sunday across most of the central, including right here in Indiana.

    This warmer regime is the sign of stormy times that will develop as we move into Tuesday.  An initial round of showers and thunderstorms will impact central Indiana Tuesday morning and the HRRR forecast radar is picking up on this nicely, especially during the predawn hours.

    The wet, stormy start to the day will give way to a mostly dry time of things through the majority of the daylight hours Tuesday, but our concentration will be on the Tuesday night-Wednesday morning period, as the potential exists for some rather turbulent weather.

    We note the National Weather Service’s Storm Prediction Center outlines all of the region for the chance of severe weather Tuesday night and also note the possibility the “enhanced” risk area may expand in future updates.  Additionally, given some of the ingredients we’re observing this evening, there’s also the possibility we may see an upgrade to a “moderate” risk for portions of the region.  It’ll be particularly important to pay attention to weather updates Tuesday night.  Primary concerns are for large hail and damaging winds in a possible squall line that develops ahead of an approaching cold front.  Additionally, if storms develop ahead of the primary line of storms, the potential exists for a couple of tornadoes.  Have a means of getting the latest watches and warnings Tuesday night.

    Modeled radar suggests things may begin to get “busy” around these parts late evening and during the overnight.  The latest high resolution NAM (hot off the press as of this update) paints a rather ominous look as midnight nears Wednesday morning.

    We then note modeling bringing the squall line through central Indiana during the overnight and predawn hours.  We’ll have to fine tune timing as we move through the day Tuesday, but we bracket the hours of 2a and 6a when a concentrated line of strong to severe storms rumbles through the state (northwest to southeast).  Hail and damaging straight line winds are of greatest concern, but a quick spin-up tornado can’t be ruled out.

    Our weather will turn quieter, but colder, as Wednesday progresses into Wednesday evening, including blustery conditions with falling temperatures.

    A fast-moving clipper system will dive southeast Thursday evening into early Friday morning and this could produce a snow shower, or two, across the region, but shouldn’t amount to much from a snow perspective (keeping true to the tune of the winter, heh?).  The bigger story will be the “rude” feel to the air mass as we wrap up the work week, as highs only reach the upper 30s with a gusty wind.

    That said, the chilly late week conditions won’t last long, and a gusty southwesterly air flow will develop as early as Saturday.  This will help give temperatures a significant boost Saturday afternoon after a cold start to the day.  60° is possible Saturday afternoon and the mercury may approach 70° Sunday!

    More updates in the AM!  Have a great night, friends!
