Battle Developing Mid/ Late June

As we progress into another weekend, weather conditions simply couldn’t be any better for this time of year.  The back half of the weekend will transition to one that’s more unsettled and feature showers and thunderstorms for Sunday.  Modeling today is backing off on the heavy rain event Sunday and hitting another system coming through the pipeline Tuesday into Wednesday with heavy rain.  We’ll keep an eye on things and update our forecast Friday morning.  Regardless, let us worry about Sunday and you be sure to enjoy Friday and Saturday!

The pool of cool will keep things feeling might nice through the first half of the weekend, along with low humidity and plenty of sunshine!

As we look into the long range, there are some questions that arise.  The questions don’t have to do with warming that’s likely to take place late week 2 (90s within reach), but just how long that ridge and associated dome of heat hangs around.  The European ensembles would imply the bubbling heat ridge will stick around for a few days.

Meanwhile, it should be noted that the European weeklies disagree with its own ensemble package as they bring a cooler pattern and associated trough back into the Great Lakes and northeast region as we get set to head into the last week of June.  Due to licensing issues we can’t show the European weeklies here, but they deliver quite the trough and cooler than normal air mass around, or just after, the 23rd.

Additionally, the PSD agrees and delivers a cool pattern around June 20th.

So, while we’re likely to see the hottest weather of the season so far towards Day 10, confidence of this hot weather sticking and holding is very low.  Timing will have to be resolved as it always does in long range weather.  Overall, what’s more likely to happen is that this will be a transient hot pattern and we flip the script to one that’s cooler than average as we go into the last week of the month.

Saturday Morning Weather Chit-Chat!

A beautiful weekend is underway.  Stepping out on the deck this morning for my morning coffee was much more refreshing when compared to the past few days.  Dew points in the 40s along with temperatures around 60 made for a very nice feel this morning.

This morning’s visible satellite shows clear skies continue.  Definitely plan to get outside today, but with that sun screen!

Most of Sunday will be nice, as well, but clouds and humidity levels will increase Sunday afternoon and evening and a couple of showers and thunderstorms will be possible as early as Sunday night.

Future radar shows scattered thunderstorms around the region Sunday night.

Warmth and humidity will return to oppressive levels for the better part of next week and this will help add fuel to the fire for heavy rain and potentially strong thunderstorms.  Model data handles the timing differently with next week’s storm system (as is usual at this stage), but agrees on the heavy rain potential.  Widespread 1.5″ to 2″ rainfall appears to be a good bet at this point next week.

Upcoming 10 day rainfall potential, per the Canadian forecast model, shows the wet pattern unfolding, including excessive rains for some locales.

The GFS (below) pushes the front south a bit quicker and in return delivers drier air next weekend.  The European forecast model doesn’t agree.

Also of interest, the GFS continues to spin up Gulf of Mexico “mischief” late next week…

Custom IndyWx.com Forecast Updated 04.09.14 @ 8:31a

Sunshine Returns; Warming Up. . .Instability-driven thundershowers developed Tuesday afternoon across central Indiana and even produced small hail in a few locations, especially east of the city.  Thankfully though the sunshine we experienced Tuesday evening is a sign of things to come for the mid week stretch.  We forecast a mostly sunny to partly cloudy sky both today and Thursday, along with moderating temperatures.

A strong southwest breeze will help usher in potentially the first 70 degree day of the year Thursday.  We also note winds may gust upwards of 30 MPH (especially in the open country) Thursday afternoon.

Late Week Front. . .A cold front will move through the region during the day Friday.  Latest model data suggests a little more moisture will be available than we thought earlier this week and as a result we’ll hit the shower and potential thundershower chance a little harder Friday.  Anywhere from 0.25-0.50 of rain will be possible with this system as it moves through the area.

Watching The Weekend. . .While Friday’s front will only make it so far south, we’re still thinking Saturday will be rain-free for the majority of central Indiana.  We’ll note the threat of a shower down state and keep a close eye on things, but for now we’ll keep Saturday’s forecast dry and warm.  Get out there and enjoy a beautiful day!

Our next storm system will take aim on the region Sunday.  As such, clouds will increase and shower and thunderstorm chances will be on the rise as we go through the day.  We do note a rather large range in model forecast temperatures Sunday between the middle 70s per the European data to the lower 60s per the GFS.  For now, we’ll split the difference and forecast upper 60s Sunday with increasing rain chances as we progress through the day.  Stay tuned.

Brief, But Potent Blast Of Winter Chill. . .Another significant rain maker will blow through the region Sunday night into Monday.  At this early stage in the game, there’s a rather high probability of moderate to heavy rainfall (greater than 1″), but the bigger story will likely be the blast of winter-like chill that will invade next Monday night into Tuesday.  In fact, there may be just enough moisture lingering to result in some light snow or flurries Tuesday as the cold air pours in.

Upcoming 7-Day Precipitation Forecast:

  • 7-Day Rainfall Forecast: 1″ – 1.5″
  • 7-Day Snowfall Forecast: 0.00″
