We continue to monitor a line of strong to marginally severe storms in Central Illinois that’s moving toward Indiana between 35-40mph. Thus far wind gust reports have been in the 40-55mph range. While widespread severe wind is not anticipated… a localized severe gust is possible in western Indiana before the line weakens.
The weakened leftovers impact the Indy metro area between 11pm-1am and quickly depart by 4am. Additional showers and heavy storms are possible by sunrise Monday. The entire WTHR viewing area is under a risk for severe weather Monday… with the main timing expected to be 2pm to 7pm. It remains unclear where storm initiation will occur tomorrow, and it’s possible initiation may be just east of Indy. Stay tuned for updates as it could impact practice at the Indianapolis Motor Speedway.
Happy Mother’s Day and the sixth straight day in the 80s! This marks only the 7th time on record with a six day or more streak in the 80s during May 1-10 for Indianapolis… and the first occurrence since 2001.
Despite isolated downpours we ‘ve enjoyed a lot of dry weather today, though cloud cover has been ominous due to high levels of moisture and low cloud bases.
Scattered heavy showers and storms increase in the southern half of Indiana the next few hours and this area may prove to be the wettest this evening. Elsewhere should be mostly dry for evening plans with Mom.
We’ll monitor upstream storms over Missouri as they’ll approach the Illinois/Indiana state line around 10pm with gusty wind and downpours. Additional showers and locally heavy storms may redevelop by sunrise Monday. So areas of heavy rain and thunder are very possible during the morning commute.
Another round of storms, possibly severe, will impact the region Monday afternoon including the opening day of practice at the Indianapolis Motor Speedway. All of Central Indiana is under a 15% probability of severe weather Monday. Though damaging wind will be the primary severe threat tomorrow… there is a non-severe tornado risk. Stay weather aware Monday and check back frequently as the forecast may change depending on how much morning cloud cover/rain/storms we see. The longer clouds and rain hold, the less unstable the atmosphere becomes. This could limit severe potential.
The passage of cold front Monday night delivers a refreshing change of pace for mid-week. Less humid, much cooler and breezy conditions are the story Tuesday with highs in the mid-60s. Wednesday may be the pick-of-the-week with morning lows in the 40s, highs in the upper 60s, sunshine a light wind.
Rain/storm chances return Friday and linger into next weekend. It’s too early to narrow down timing and coverage, but impacts to Saturday qualifying and Pole Day Sunday are possible. Check back during the week – Sean Ash
Unseasonably warm air continues to claim real estate over a good portion of the eastern United States… including Central Indiana. Highs soared back into the mid and upper 80s for the third straight day. We’ll remain some 15 degrees above average through the weekend, but chances of showers and storms do increase tomorrow night.
Unfortunately a multi-day severe weather event unfolds in the Central Plains with high chances of tornadoes (some possibly significant and long-track) Friday and especially Saturday. Here in Indiana we’ll be far removed from the more substantial jet stream energy and wind shear for organized severe weather. But a locally strong or severe storm is in play Saturday and Sunday afternoon with heavy rain likely in anything that does develop.
A few leftover showers from overnight upstream storms may sneak across the IL/IN state line Friday morning. Isolated showers and storms are also possible Friday afternoon, but much of tomorrow will be similar to the past three days… warm and mainly dry. However storms may increase from west to east toward sunset Friday and then play a role in how Saturday begins.
While we don’t envision washouts, at this point, but you’ll definitely need to monitor the radar closely if you plan to attend the 500 Festival Kid’s Day and Rookie Run… or the Grand Prix of Indianapolis on Saturday. Mother’s Day remains unsettled but unseasonably warm. Scattered showers and storms occur and especially during peak heating. We’ll need to monitor Monday for severe storm potential as the upper low approaches the Ohio Valley.
This will also mark the transition from unseasonably warm to near normal conditions next week… albeit significantly cooler and less humid than this week. Please check back for updates to the weekend forecast – Sean Ash
Afternoon temperatures soared into the middle and upper 80s across Central Indiana. This is a good 15 degrees above normal and good for the warmest day in Indianapolis since September 5th when it was 90 degrees.
If you’re a fan of summer warmth then you’ll love the continued June-like pattern that continues into the weekend. If not then you’re going to have to endure lows in the 60s and highs in the 80s until early next week.
Expect a hazy, warm evening with sunset not until 8:44pm. So plenty of time to get out and enjoy. Thursday will be a carbon copy of today with morning temperatures in the 60s and afternoon highs back in the mid-80s. Don’t forget the Indianapolis Indians wrap up their latest home stand tomorrow with a late morning first pitch at 11:05am. Pack the sunglasses and dress in light clothing to stay comfortable.
The morning and early afternoon will be mainly sunny with fair weather cumulus developing during the heating of the afternoon. Rain chances remain very isolated until after sunset Friday. Unfortunately this coincides with several events this weekend. It’s possible that the remnants of overnight showers and storms may linger around early Saturday morning when the gates open at the Indianapolis Motor Speedway. 500 Festival Kid’s Day/Rookie Run festivities begin on Monument Circle at 10am. Take some rain gear and dress for warm, humid conditions.
The higher storm chances will be during the afternoon and evening of Saturday and these could impact the 2nd Annual Grand Prix of Indianapolis. Though the race is rain or shine… lightning could cause some delays. Weather for Mother’s Day will be unsettled with the potential for multiple rounds of showers and storms… some possibly strong.
Monday remains active with a good chance of heavy storms and possibly some severe weather too. This marks the transition from unseasonably warm conditions to cooler, albeit closer to average, air Tuesday and Wednesday of next week. Please check back for updates on timing and coverage of storms this weekend – Sean Ash
Can you feel the increased humidity today? We had to dust off the Muggy Meter with dew points near or above 60 degrees for the first time in awhile.
This low-level moisture teams up with a weak cool front, daytime heating and strengthening low-level jet stream to trigger some heavy storms this evening and into Tuesday morning.
While organized severe weather isn’t anticipated… some gusty storms with hail are possible. But heavy rain and lightning will remain the main storm threats until further notice. The focal point for storm coverage will be along and north of a warm front draped along the I-74 corridor.
The warm front lifts into northern Indiana by Tuesday afternoon and stall along the Michiana border. This area becomes the focal point for storm coverage for a few days, and south of this front becomes mainly dry and much warmer as highs climb into the 80s.
This stretch of unseasonably warm air carries into the upcoming weekend, but storm chances return Saturday and Sunday. As of now the greatest coverage of storms Saturday will most likely be in the afternoon and evening. So it’s conceivable that much of the 500 Festival Kid’s Day & Rookie Run festivities may remain dry.
However we’ll need to radar watch later that day for potential impacts to the Angie’s List Grand Prix of Indianapolis. Mother’s Day looks unsettled in the Ohio Valley and includes heavy storm potential. Check back for updates on timing and coverage as we get closer to the weekend – Sean Ash
We’re enjoying a rather warm start to the month of May. Highs Sunday hit the upper 70s and lower 80s… which is a good 10 degrees above normal. The warmest air is yet to come and we’re staring down a prolonged stretch of highs in the lower to mid 80s this week.
Expect a very pleasant evening with comfortable conditions and refreshing breeze. Showers and storms to our west serve notice of rain chances returning to Central Indiana tomorrow. Tonight and the early morning hours of Monday should be dry, but by late morning it’s fair game for scattered showers.
While we don’t anticipate organized severe weather, there will be locally heavy storms that develop along an approaching front and within maximum heating. Lightning and downpours are main threats with storms tomorrow.
This front retreats back to the north after Tuesday morning and will be the focal point of storm coverage along the Michiana border. South of this boundary Central Indiana will be mostly dry until next weekend, with summer-like heat building into the Ohio Valley.
Temperatures will be consistently 10-15 degrees warmer than normal into next weekend. It appears will have to dodging showers and storms next weekend, though it’s too early to determine timing and coverage. Stay tuned and this could possibly impact the Angie’s List Grand Prix of Indianapolis next Saturday afternoon. Have a great evening – Sean Ash
Widely scattered showers and storms over southeastern Indiana should quickly depart by 5pm. It appears some showers will wrap westward around the center of an upper low as it dives toward the Ohio River this evening. With the cold-core overhead we can’t completely rule out cold air funnels… though admittedly it’s a slim chance.
The departure of this upper low sets up the much advertised weekend warm up. However, we’ll have to endure another seasonably chilly night in the 30s and lower 40s
But we’re back to mostly sunny conditions Friday with highs nearing 70 around 5pm. If you’re in town the the Mini-Marathon you should make it over to Victory Field Friday evening. It will perfect weather for the Indianapolis Indians to get back on the winning track at Victory Field.
There are no significant changes to the our 500 Festival Mini-Marathon forecast. It still appears there will be some residual cloud cover from a weakening upper system arriving predawn Saturday. This may limit sun at the beginning of the race but expect mostly sunny conditions for the later waves of runners.
Otherwise it’s ideal conditions for the race with temperatures near 50 degrees at 8am with a calm to light wind. Temperatures quickly warm into the mid-60s by 11am and upper 60s by 1pm. Highs top out in the lower 70s and get ready for a fabulous Saturday evening for the Rev Indy Event at IMS.
Opening Day at the track looks spectacular as well. Morning temps in the 50s when the gates open at 9:30am and highs in the mid-70s with a good deal of sunshine. All long range guidance points toward an above to much above normal first week of May with highs mainly in the 80s! At this point it appears the greatest rain/storm chances next week may be in the northern third of Indiana. We’ll update as needed – Sean Ash
We’ve had this is in our forecast since Monday, and now have had reports of small hail with lightning in stronger cells that have developed within the past hour. The much colder air aloft combined with spin around an upper level low overhead may produce some cold-air funnels too. This rarely ever reach the ground but can be a bit alarming to the untrained eye. The best chance of seeing one will likely be on the eastern and southeastern half of the state today.
Showers and storms diminish quickly toward sunset as the upper low pivots south of the Ohio River. This paves the way for a pleasant weekend warm up that will see temperatures rise into the 70s for highs. We’ll post an updated long range forecast shortly as it appears the first week of May will be in the 80s!
