Here are some images I put together, explaining out severe weather threat for tomorrow and tomorrow night.





A violent severe weather outbreak is looming for a large portion of the nation including the Plains, Midwest and Ohio Valley. A strong low pressure system will develop and move into Iowa and Wisconsin by late Monday Night.
Initially a warm front will lift northward across the Oho Valley on Sunday Evening. Some elevated thunderstorms will likely develop along the warm front and some of those could become strong or severe by Sunday Evening and Sunday Night. The main threat with any thunderstorms on Sunday Evening and Sunday Night will be some isolated large hail and heavy rainfall. To our Southwest and West a major and violent tornado outbreak is possible across Missouri, Western Illinois, Arkansas and Oklahoma.
Current forecast guidance is pointing towards the violent severe weather outbreak contining on Monday Afternoon and Evening across the Midwest and Ohio Valley. The latest forecast guidance shows the low deepening and moving into Northern Wisconsin with a cold front trailing into Missouri by Monday Evening. That will leave all of Indiana and Western Ohio in the warm sector.
The Triple Point will pass over far Northern Indiana and that could enhance the tornado threat. Also with temperatures climbing into the 60's and lower 70's and dewpoints climbing to near 60, the storm system will have plenty of instability to work with. Large hail and tornadoes will be a threat with any discrete storms/supercells early Monday Evening. But as the upper-level winds strengthen, I feel that the storms will likely congeal into a MCS or squall line. The storms will still pack a punch Monday Night with damaging winds and if the updrafts in the squall line can continue to rotate, then hail and isolated tornadoes will continue to be a threat.
Finally, with PWATS over 1.25 inches, heavy rain is a distinct possibility and thus more flooding could occur. 2-4 inches of rain will be possible by Tuesday Morning.

With Winter officially coming to an end, Spring will be welcomed with renewed heavy rainfall and thunderstorms. Warmer temperatures will arrive early next week with temperatures climbing above-normal on Sunday and Monday.
The main weather concern early next week will be the possibility of additional heavy rainfall. The first three months of this year have brought Eastern Indiana and Western Ohio over 200% more precipitation than normal, explaining why we are experiencing constant flooding problems. The soil remains 150% saturated and many streams and rivers remain in a flood stage.
Rain will likely begin Sunday Night and will continue into Monday and Tuesday. Rainfall amounts will likely exceed three inches by Tuesday, and the possibility is there for quite a bit more than that. Thunderstorms will also be possible on Monday and Tuesday and with above-normal temperatures and a strengthening weather system, some strong thunderstorms are not out of the question.
Looking ahead to the rest of the Spring weather season, it appears that our weather is going to continue to be influenced by the weather phenomena called La Niña. The term La Niña means that ocean temperatures in the Eastern Pacific off the coast of South America are colder than normal. This affects the weather across the United States in many ways, primarily by causing storms that form to be stronger. Here in the Ohio Valley, we typically experience much wetter Springs when the weather pattern is affected by La Niña, and that will almost definitely be the case this Spring.
With that in mind, flooding and over-saturated soils will continue to plague Eastern Indiana and Western Ohio through at least June.
So while the phrase "April showers bring May flowers" often is true in most Spring weather seasons, this year we will probably have to change that phrase to say "April showers bring more May flooding."

Yet another stormy pattern is looming. Storm systems are lining up across the Pacific.
The first storm will impact the region Wednesday Night through Friday. The storm will dig into the Ohio Valley and a warm front will stretch from Springfield, Missouri to Cleveland, Ohio. The exact placement of this low will divide the colder part of this system from the warm sector where heavy rain rain and strong thunderstorms will be possible. In fact, I am leaning toward the idea of a winter weather event for the Northern third of Indiana on Thursday Night and Friday. Simply amazing, stating that it is almost April! The rest of Indiana and all of West Central Ohio will experience warmer air and the potential for heavy rainfall. In fact, our latest model guidance points towards the possibility of 2-3 inches of rainfall. While I am not confident at this point on this aspect of the storm, strong and severe storms could be possible Thursday Afternoon.
Storm Number 2 will arrive here on the last day of the month. That storm system looks to be a widespread severe weather maker, but more on that later.
Just Take A Look At How Large This Storm Is! This is a picture via Google Earth showing just how large this storm is and how much precipitation is out there! JUST AMAZING!
Heavy rainfall is currently overspreading the state of Indiana and will continue to plague Indiana and Western Ohio through tomorrow night. Total rainfall accumulations could exceed 5 inches in some locations. With an already over-saturated ground, river and aereal flooding is likely tonight and tomorrow and flash flooding is not out of the realm of possibilities.
This is a dangerous situation. To our Southwest, portions of Southern Illinois and Southeastern Missouri have already experienced almost 12 inches of rain and are reporting record flooding. In fact we have gotten several reports of fatalities across the area.

THUNDERSNOW REPORTED.
First of all, thundersnow being reported all over Northern Montgomery County and in the Dayton area.
Second of all, there are two primary bands of snowfall. The first from Louisville to Dayton which is alowly retrograding to the Northwest. The second extends from Evansville to Fort Wayne and is moving East. Both bands are currently producing snowfall rates of over an inch per hour, and as the bands merge over Southern and Eastern Indiana and Western Ohio, extremely intense snowfall rates will be possible as the band will become stationary for several hours. The heaviest snow will fall from Louisville through Celina, Ohio through 4:00 AM.
Snow is redeveloping across the area and will become heavy at times. The heaviest snow will fall just East of a line from Evansville to Indianapolis to Fort Wayne. I am noticing some convective elements developing, and some lightning strikes and thundersnow are possible.
Winds are howling here as of 9:00 PM and will create full-blown blizzard conditions overnight and on Saturday. Blowing and drifting will create extremely hazardous road conditions and many roads will become impassible.


The radar image above shows where the heaviest snow is currently falling and where it will move during the next 2-3 hours. Snowfall rates will continue to increase and road conditions will continue to worsen.

IndianaWeatherOnline.com has once again added yet another feature, our brand new Winter Mosaic Precision StormTracker Doppler Radar.
This radar is still in testing, and we are looking for comments as to whether you like the new radar!

It still appears a considerable snow event is on the way. The most likely areas for heavy snow will be East and South of Indianapolis and across all of Western Ohio.
Winter precipitation is already developing across parts of Arkansas and Southern Missouri. This area will continue to expand and move Northeast towards the Ohio Valley. Snow will likely be falling by as early as 9:00 AM tomorrow morning across the area and will become heavier as the day progresses. There will likely be a brief break tomorrow evening before round number 2 of the heavy snowfall arrives by late tomorrow night and into the day on Tuesday.
Winds will also be strong across the area, with winds gusting as high as 40 mph. This will create considerable blowing and drifting along with whiteout/blizzard conditions.
Total snowfall accumulations will arrive in the double-digits by Saturday Evening for areas East and South of Indianapolis and across Western Ohio.
The largest snow event of the season is likely across the Eastern and Southern parts of Indiana and Western Ohio on Friday and Saturday. A strong low pressure system will ride Northeast along a stalled frontal boundary that will extend through Northern Kentucky.
Heavy snow will develop by early Friday Morning across the area and continue through the day on Friday and into Saturday. Some sleet may mix in aross far Southeastern Indiana south of Decatur County. Snowfall rates could be quite high at times, with as much as 1-2 inches falling per hour.
As the system strengthens and approaches the Ohio Valley, significant winds will also accompany the snow, and significant blowing and drifting is likely. Blizzard Conditions will be possible.
Total snowfall accumulations will be in the double-digits across a large portion of the area.

Yes, if you haven't already heard yet, I am predicting a major snow storm across the Eastern and Southern parts of Indiana and Western Ohio on Friday. A boundary will stall out across portions of Kentucky and extend Southwest into Oklahoma. It appears that several areas of low pressure will travel along the front and provide the area with some very heavy snowfall beginning early Friday Morning and continuing into early Saturday.
With temperatures being colder than we've seen with any other storm, the "fluff factor" or liquid to snow ratios could be much higher, which will just enhance snowfall totals.
I think as much as a foot of snow if not more could fall across areas East of a line from Evansville to Indianapolis to Fort Wayne. West of that line, 2-4 inches will be possible across the Northwestern and Western parts of Indiana.
As far as tonight goes, I still feel like conditions as far as utility lines goes will get worse before it gets better. Snow is rapidly developing across Central Indiana with 2-3 inches of snow possible across Central Indiana and 3-6 inches of snow possible farther North. This combined with winds which will pick up and gust to 40 mph overnight will add extra burden and weight on utility lines, so more downed lines are possible.
We are watching another storm system that could affect the area on Thursday and a larger one for Saturday, but more on those tomorrow, for now lets get through this storm!
It appears the back end of the precipitation may be getting a little closer. It looks like we will see another 1-2 hours of this heavy freezing rain and sleet before the precipitation begins to lighten across the area.
Another batch of precipitation will likely develop later this evening and could bring another round of freezing rain, sleet and snow to the area with snowfall accumulations possible North of Interstate 70.
There are numerous reports of power outages, powerlines and trees down and transformers on fire across the area. This is a dangerous situation, so if you can just stay home tonight!
Getting widespread reports of power lines and trees down across the area. Heavy freezing rain will continue across the area for the next several hours, and with thunder and lightning embedded in this area of precipitation, precipitation rates will be enhanced across the area.
It looks like there will be a brief break across the area later this evening before snow fills back in across the area.

Also now have powerlines down and arching on State Route 227 at 600 South in Randolph County.
As of 2:00 PM, I am getting reports of power outages in Northwestern Wayne County and in Northeastern Henry County. Precipitation is really intensitying across the Southern half of the state, and I believe conditions will only get worse across the area! Temperatures are down to 29 here and 28 in Muncie, also the lower 30's across portions of Northern Wayne County.
As far as road conditions, am getting reports of numerous accidents across Delaware, Madison and Darke County, Ohio. Also am getting reports of roads under water in Darke County due to the flooding.
Yes Thunderstorms, an area of widespread thunderstorms have developed South of I-70 with plenty of lightning and even some small hail! This will only enhance the freezing rain and sleet as the thunderstorms move into the colder air North of I-70!

Each one of those lightning strikes, indicates a lightning strike in the last 5 minutes!
We continue to get freezing rain here with temperatures hovering right around 30. We have gotten multiple reports of widespread power outages in Hamilton County in the Fishers area and also some in Southeastern Randolph County. Precipitation continues to back-build across Southern Indiana and in fact we have severe thunderstorm warnings and flash flood warnings in effect for areas just North of Louisville.
Here is a link that you can visit to view the latest power outages across Central Indiana. They definitely have continued to increase over the past several hours.

Temperatures are looking colder and colder across the area, and much colder than earlier forecast models predicted. Temperatures are already down to 35 in Muncie, 34 in Lafayette and 36 in Indianapolis. Here at IndianaWeatherOnline.com we are down to 35.6 degrees and the temperatures have fallen over 6 degrees in the last 3 hours!
I still fully expect a major ice storm across the Northern half of the state of Indiana and still expect the heaviest ice to fall from Noblesville to Muncie to Greenville, Ohio. As much as an inch of ice may accumulate, and that may be on the conservative side!
Farther South along Interstate 70 and areas such as Indianapolis and Richmond, the colder air is moving farther South much quicker, and I definitely expect freezing rain to develop by tomorrow morning in your areas. Between a quarter and a half inch of ice is expected.
The far Northern parts of the state will see a sleet and snow mix and could see 3-6 inches of a combined sleet/snow accumulation.
Flooding will continue with plenty more precipitation on the way! Flooding could be extreme across parts of the Central and Southern aprt of the state.
Precipitation will change to all snow by Tuesday Afternoon for areas along and North of Interstate 70 and in fact, our latest forecast models are indicating the potential for several more inches by Tuesday Evening!
Stay tuned and definitely stay safe!
