Mostly Dry Weekend Before Storm Chances Return…

Screen Shot 2016-06-18 at 7.53.29 AMHighlights:

  • Mostly dry and hot weekend
  • Humidity levels on the rise Sunday
  • Storm chances return

Put On That Sunscreen…High pressure will supply a beautiful open to the weekend, including mostly sunny to partly cloudy skies, low humidity levels, and warm temperatures.

Our airflow will shift to the SW Sunday and help push a more humid air mass back into the state as the day progresses.  An isolated thunderstorm could accompany the return of the humid air, but for now we’ll maintain a mostly dry forecast.

Better thunderstorm chances arrive Monday evening into Tuesday as a cold front pushes in from the north.  A locally strong to severe storm is possible.  As we move forward into the middle and latter parts of next week, models suggest a rather unsettled time of things.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 1″-2″

Video Update: Stormy For Some This Afternoon…

Do we rid the morning convection and cloudiness to allow strong to severe thunderstorms to develop this afternoon and evening?  This morning’s video has more.

Strong Storm Threat Wednesday…

Screen Shot 2016-06-14 at 9.27.06 PMHighlights:

  • Scattered strong-severe storm threat Wednesday
  • Drier close to the week
  • Next front arrives Monday PM

Keeping An Eye On Wednesday’s Storm Threat…Today’s rain numbers weren’t uniform in the least, but several neighborhoods picked up beneficial rains of over 1.5″.  Wednesday will also feature the threat of showers and thunderstorms (again, some with locally heavy downpours).  Some of these storms could also reach strong to severe levels during the afternoon/ evening, particularly if morning rain doesn’t “get in the way.”  We’ll watch data overnight and update accordingly come morning.

We’ll turn drier and slightly cooler to close the work week and head on into the weekend.  The heat will begin to crank again early next week, with highs around 90 Sunday and Monday.  Our next weather maker looks to arrive Monday evening as a cold front pushes in from the north.  We’ll feature shower and thunderstorm chances in our Monday PM forecast.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 0.50″-1.00 (locally heavier totals)

Some Thoughts Into Late June…

The first (12) days of June are in the books and we’re running drier and warmer than average, month-to-date.  Officially, IND reports a temperature departure of 3 degrees above normal and a rainfall deficit approaching 1″.

As we look ahead, the pattern is one that seems to favor the most sustained hot dome (mean ridge) position across the 4 Corners region and Southwest states.  This morning’s European ensemble data shows this well:

Ck1DCVXWsAEGcde.jpg-largeThe teleconnections aren’t much help in trying to generate longer term thoughts.  They would favor more of a “normal” period temperature-wise, locally.  (BTW, thanks to the fine folks at MAD US Weather and ESRL for the data below).

On another note, there are different times through the year when the respected positive and negative phases of the teleconnections below have more of an impact on our weather, particularly during the fall through spring months.

JuneTellesLooking at some of the model data, the general consensus is for a warm look to go through the back half of the month, but we caution that we can’t simply “broad brush” the forecast through the EOM as warm and relatively quiet (a note on that in a moment).

gem-ens_T2maMean_us_7

gfs-ens_T2maMean_us_7As mentioned above, despite an overall warm look on the models there will likely be periods of cooler “jabs” and it sure looks like a rather transient pattern to us across the Mid West and Ohio Valley, featuring more of the sustained heat across the Southwest region.  Transient patterns usually also yield for potential wetness and we note the GFS Ensembles trending in that direction to wrap up the month.

gfs-ens_apcpna_us_10In the shorter term, there will also be localized heavy downpours, but it’s a continued case of “haves and have nots.”  There won’t be any particular rhyme or reason to the specific placement of heavy, gully-washer type showers and storms mid week.

Finally, to close, perhaps the MJO shows the pattern best over the next couple weeks.  Best word to describe the MJO’s idea?  Transient.  🙂
