Awesome Weekend Weather Continues; Changes Ahead Next Week…

Highlights:

  • Spring-like weather rolls along
  • Shower chances return
  • Strong t-storm potential
  • Different tune next weekend

Is This February?  Our stretch of unseasonably pleasant, spring-like, weather will continue for the second half of the weekend and as we progress into the early stages of the work week.  Find a way to get outside the next couple of days (that’s an order ;-)).

A weak weather system will scoot through here Tuesday and serve to increase our cloud cover, along with a few scattered showers.  Dry conditions return Wednesday, but by then all eyes will be on an approaching stronger storm system that will provide increased shower coverage by Thursday and strong to severe thunderstorm potential Friday.  Speaking of severe weather, we think this spring will offer up a busy severe weather season.  We’ll have additional updates on the severe potential as time gets closer, but just keep a mental note Friday could be a busy weather day.

We’ll abruptly transition back to winter Friday night and the air will grow cold enough a week from today to allow scattered snow showers to fly in a gusty northwesterly breeze next Saturday.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: Trace – Dusting
  • Rainfall: 0.50″ – 1.00″

Thoughts Shift Towards Severe Weather Season…

With the unseasonable warmth this week, our thoughts begin to shift to the coming spring months ahead.  Of course with spring comes the potential of storms- some of which include severe weather outbreaks.

Already, 2017 has wasted no time in the tornado department, year-to-date- more than double the (10) year average across the United States.

The Gulf of Mexico is boiling warm (running 1°-3° C above normal) and this will aid in transporting moisture-rich air north.  As storms eject out of the Rockies and Plains, one would tend to believe anomalously warm dew points and precipitable water values will be available.

The JMA Weeklies show an active stretch developing as we progress through the next few weeks.

As we rumble deeper into the spring months, the mean trough position should be located across the west.  The end result should be a mean storm track that runs into the Ohio Valley- courtesy of resistance from an eastern ridge (that warm water in the Gulf and East Coast screams the mean ridge position should be located across the east coast).  Confidence is greater than normal on a busy severe weather season.

Much more later as spring evolves.

Buckle Up: Spring, Winter, Spring…

Screen Shot 2017-02-07 at 7.04.56 AMHighlights:

  • Periods of storms Tuesday
  • Snowy Wednesday for some
  • Warming back up this weekend with storms

Dramamine Required…The “tug of war” weather pattern will continue through the forecast period with winter and spring each having difficulty taking control for any length of time…

Walking out the door this morning will have you checking the calendar to see if it, indeed, is early February.  As we type this Tuesday morning, temperatures are in the lower 60s across many central IN neighborhoods.  That unseasonably warm air mass will help fuel t-storm development through the mid afternoon hours and a couple of these storms could reach severe levels, including damaging winds.

The cold front will sweep through the state this afternoon putting an end to the storminess and resulting in colder air spilling into the region tonight.  A disturbance will quickly move into the colder air mass Wednesday and this will result in an area of snow developing during the day.  This is a tricky system as the recent warm, wet ground would argue against much, if any, accumulation.  However, localized banding features likely will lead to more intense snowfall rates across portions of north-central IN Wednesday afternoon-evening and this would overcome the warm surface temperatures and lead to local slushy accumulations.  We feel at this time, the best bet for a potential 1″-2″ slushy snowfall will be just north of the city and we’ll have a snowfall forecast map out this evening (want to give the 12z modeling a good look).

We’ll turn much colder Thursday before wrapping up the work week with a windy, milder feel Friday.

The next storm will arrive over the weekend and serve to give the thermometer another spring-like look, but, similar to today, storms will follow Sunday…

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 1″ – 2″
  • Rainfall: 0.75″ – 1.25″

Touching Base Monday Evening…

That sunshine sure was nice…while it lasted. Clouds lowered and thickened through the afternoon and a wind-driven mist is falling across most of central Indiana this evening. That mist will…

Nice Today; Busy Weather Week Ahead…

Screen Shot 2017-02-05 at 8.48.07 AMHighlights:

  • Lots of sunshine for Super Bowl Sunday
  • Rain and storms early week
  • Mid week snow

Beautiful Super Bowl Sunday; Changes Await…We suggest taking your pregame Super Bowl parties outside today to enjoy what’ll be a rare sunny day!  Temperatures will also be milder today, topping out in the upper 40s.

Unfortunately, the sunny skies won’t last as clouds increase Monday morning and showers move in by afternoon.  As surface low pressure tracks into the Great Lakes, heavier rains and embedded thunderstorms will increase Monday night into Tuesday morning.  A couple of these storms could become strong to severe, and include strong and damaging winds and hail.  Colder air will pour into Indiana on gusty northwest winds Tuesday night behind the frontal passage.

Our attention will then shift to a colder regime for mid week.  We have to iron out the details, but forecast models suggest an area of low pressure will scoot across the central Plains to the East Coast Wednesday into Thursday.  This will spread moisture north into the colder air mass and the result may be a swath of accumulating snow north of the low’s track, including central Indiana.  We’ll be left with very cold air to wrap up the work week.

Next weekend, the “tug of war” regime will continue.  Southwest winds will usher in milder conditions Saturday with showers.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 1″ – 2″
  • Rainfall: 0.75″ – 1.25″

Friday Morning Rambles; Looking Ahead…

1.) A cold close to the work week can be expected with highs today only topping out in the upper 20s (average highs are in the upper 30s).

gefs_t2ma_1d_noram_52.) What at one time looked to be a significant weekend storm now may not even deliver any precipitation at all to the region.  A flurry is possible, but most should remain precipitation-free this weekend. Expect a gusty southwest wind developing SB Sunday.  Highs around freezing Saturday will zoom into the middle 40s Sunday.  Lows Saturday morning in the middle 10s will rise into the upper 20s to around 30 Sunday morning.

gfs_ptype_slp_conus2_93.) A more significant storm system will cut for the Great Lakes early next week and this will deliver gusty showers and embedded thunderstorms.  A couple of stronger storms aren’t out of the question.  Locally heavy rains can be expected, including amounts of 1″-1.5″ (locally heavier totals).

gfs_ptype_slp_conus2_19

gfs_tprecip_indy_224.)  Cold air will rush back into the region behind the storm and snow showers and squalls are likely by Wednesday.

gfs_ptype_slp_conus2_22

gfs_t2m_a_f_conus2_245.) Longer-term, a real fight is developing on the overall direction we’re heading as February evolves.  Analog methods and teleconnections (shown below) would yield bullish cold signals and give hope to winter enthusiasts.  However, modeling isn’t in agreement on the wintry ideas.  In fact, some modeling is very spring-like as mid-Feb nears.  Stay tuned as we try and iron out the details this weekend. Updates will come.
