Today Is The Pick Of The Week; Wet And Stormy Pattern Looms…

Screen Shot 2015-06-13 at 9.02.37 AMHighlights:

  • Best weather of the week is today
  • Strong to severe storm potential Sunday and Monday
  • Widespread heavy rain threat mid week
  • Unsettled pattern continues

We’re opening the weekend with dry skies across central IN, along with a very tropical feel.  The combination of a nearby weak boundary and the humid air mass will help fuel isolated to widely scattered storms this afternoon.  That said, overall coverage of storms will be reduced from what we saw Friday.  Most of the day will feature dry conditions.

We’ll begin to increase storm chances as we rumble into the second half of the weekend and on into the new work week.  Some of these may be strong to severe Sunday-Monday, including strong damaging winds and large hail.

Attention will then shift to mid week and the potential of an excessive rainfall event.  Modeling is leaning towards tracking a tropical disturbance north out of the western GOM (Gulf of Mexico) before shifting northeast around the periphery of a southeastern ridge.  Very heavy rainfall would result if this idea pans out.  Stay tuned.

Upcoming 7-Day Rainfall Potential: 2″-4″ (locally heavier totals)

Storms Tonight; Heat Builds This Week…

Screen Shot 2015-06-08 at 5.57.06 PMHighlights:

  • Stormy tonight for some
  • Heat builds this week
  • Better storm chances return for the weekend

A cold front remains off to our northwest as we type this and big storms are firing across northern portions of the state.  We’ll keep a close eye on those as they move southeast tonight and begin to pick up more forward momentum in the coming hours.  They’ve had a history of producing damaging hail.  Remain weather-aware this evening.

Thankfully we’ll begin to inject a drier air mass (briefly) into the region Tuesday.  A nice day is coming with lower humidity.  Most of the second half of the work week will also remain dry, but as humidity increases we have to mention the threat of an isolated to widely scattered storm.  The big story will be the heat as highs push into the 90 degree territory.  Prepare to sweat!

Better chances of showers and thunderstorms will push back into the region over the upcoming weekend.  We’re not forecast a complete washout either Saturday or Sunday, but with a very humid air mass in place, any shower or storm that develops will have the capability of producing torrential downpours.

Upcoming 7-Day Rainfall Potential: 1.5″ – 2.5″

Very Active Night Ahead…

An active and noisy night is on tap, friends, as multiple storm clusters move through central Indiana.  Initially, the concern is hoisted for severe weather, including damaging winds and hail. As the night progresses, the growing concern will be flash flooding as storms train over the same area, potentially leading to 3″+ rains in localized areas.

We’re currently eyeing convection firing to our northwest and these storms will push southeast this evening.  They will move into a very warm, humid, and unstable environment and will likely strengthen as they ride into north-central IN later this evening.  Here’s a snap shot of the radar valid at 8p:

8pNote as we progress into the overnight, additional storms are likely and flooding concerns are on the rise due to this. Radar valid at 3a:

3aRainfall totals of 1″-2″ will be common tonight across central IN, but some localized reports of 3″-4″ can’t be ruled out where storms train.  Here’s a look at potential rainfall numbers through 5a:

hrrr_t_precip_indy_16We note PWATs (precipitable water values) pushing close to 2″ overnight and this increases our confidence on the heavy rainfall potential, as well:

hires_pwat_indy_20Stay weather-aware tonight, friends!

A Much Cooler, Drier Trend…

Screen Shot 2015-05-11 at 8.51.04 PMHighlights:

  • Much cooler and drier through Thursday
  • Moisture increases this weekend
  • Stormy early next week

A cold front swept through the state this evening and a much drier and cooler brand of air is filtering into IN as we type this.  That cooler and drier regime will carry us into late week before moisture slowly begins to return.  High pressure will shift east and allow a moist return flow Friday into the weekend.  Add in a couple of disturbances and the associated forcing, combined with the increasing warmth and humidity, and the stage is set for periods of showers and thunderstorms over the weekend.  It certainly won’t rain the entire time, but plan on localized heavy downpours.

hrrr_t2m_indy_14A MUCH cooler air mass will greet Hoosiers out the door Tuesday morning.  Even cooler air will be with us Wednesday and Thursday mornings.

gfs_ptype_slp_conus2_9High pressure will supply plentiful sunshine and cooler than normal air through mid week.

gfs_ptype_slp_conus2_16A southwesterly return flow will lead to increasing chances for showers and thunderstorms across not only our local area, but across a widespread portion of the Plains and Ohio Valley.  Furthermore, a significant severe weather outbreak appears to be a good bet across the Plains.

cmc_total_precip_indy_33After a dry mid week stretch, active times return over the weekend into early next week.  Localized torrential downpours are likely.  Most of the 1″ to 2″ of rain forecast shown above (courtesy of the GEM model off the Weatherbell.com suite) is expected to fall early next week.

Lots Of Dry Time This Weekend, But Scattered Storms Will Be Around…

Screen Shot 2015-05-09 at 10.38.36 AMHighlights:

  • More dry time than not this weekend
  • Strong storm potential Monday
  • Cooler and much drier air moves in Monday night

The region remains in a very warm and moist air mass this weekend and this could help promote a scattered shower or thunderstorm really at any point over the next couple of days.  That said, best concentration of rain and storms will come during the afternoon and evening hours.  All-in-all, the weekend will feature many more dry hours than not.  A final push of showers and thunderstorms will blow through Monday and some of these could reach strong to severe levels.  We’ll keep a close eye out.  A much cooler and drier air mass arrives Monday night and that will carry us through Thursday.

hrrr_ref_indy_10Most of today will be dry, but forecast radar (courtesy of Weatherbell.com) suggests showers and thunderstorms build into central IN this afternoon and evening.  Plan on taking rain gear with you if you have outdoor plans and have a means of getting inside should a storm be nearby.

day3otlk_0730The SPC has highlighted a large portion of the Ohio Valley for the threat of severe weather Monday.  Large hail and damaging winds appear to be of greatest concern at this time.  While this doesn’t look like a significant widespread severe weather outbreak for our immediate region, let’s remember it only takes one severe storm impacting a community to be significant in that particular neighborhood.

Summer-like Turns Much Cooler Next Week; Storms In Between…

Screen Shot 2015-05-06 at 10.29.34 PMHighlights:

  • Feeling like summer
  • Storm chances ramp up going into the weekend
  • Best chances of widespread rain arrives Monday
  • Much cooler next week

As we get set to put a wrap on another busy work week, near record warmth is the big weather story.  Those unseasonably warm conditions we’ve dealt with over the past few days will continue into the weekend, but we’ll also add rain and storm chances.  Coverage of thunderstorms will be categorized as “isolated” Friday, “scattered” Saturday and Sunday, and “widespread” Monday.  As moisture continues to surge into the region, locally heavy downpours can be expected, and a downright muggy feel.  A severe storm is certainly possible, but the more widespread severe outbreak will remain to our west across the central Plains region.  Much cooler air will pour into the region behind a Monday night frontal passage.

2As we type this (around 10p Wednesday evening), temperatures are still in the middle 70s and a whopping 15-20 degrees above average this hour across the area.

1Think it’s humid now?  Just wait until the weekend.  A strong southwest flow will pull moisture-rich air northward, courtesy of a Gulf of Mexico connection.  Dew points will approach 70 degrees across many southern and central IN communities and help fuel locally heavy rainfall with any storm that develops Friday night through Monday.

3A MUCH cooler air mass will filter into the region behind the cold frontal passage Monday night/ early Tuesday.  After a week of summer-like heat, upper 50s for highs will feel downright chilly.

Wet Today; Much Better Sunday!

Screen Shot 2015-04-25 at 9.33.34 AMHighlights:

  • Wet, at times, today
  • Increasing Sunday sunshine
  • Small rain chance mid week
  • Warming trend late week

SAT_EUS_WVENH_ANIThis morning’s water vapor loop, courtesy of Weathertap.com, shows low pressure and the associated “big spin” over the mid section.  This will continue to slowly track east, southeast as we go through today and will provide the chance of showers and embedded thunderstorms at any point today into the evening hours.  Severe weather is possible across southern IN on south into KY and TN.  Heads up if your travels take you that direction today and have a way to get the latest weather information.  A much brighter Sunday is ahead and this will set the stage for a calmer week overall when compared to this past week.

hires_ref_indy_11Forecast radar, courtesy of Weatherbell.com, shows heavier and more widespread rains lifting into the region early this afternoon.  Today’s rainfall totals, however, don’t look as heavy as what was expected earlier this week.  Now we’re thinking most will fall in the 0.50″ range, with locally heavier totals under spots that see a thunderstorm.
