It will not be an all day wash out, but isolated rain and thundershowers will be possible during this afternoon and evening. There will be several dry hours embedded throughout the day with otherwise mostly cloudy skies. Temperatures climb into the upper 70s.

Tonight: We’ll drop back near 58° during the overnight with a mostly cloudy sky.

Tomorrow: The rain showers look to stay at bay to the south on Friday. Skies will be mostly to partly cloudy with a tad bit cooler temps in the lower 70s.

Weekend Outlook: This weekend looks relatively dry with the only chance of rain being during the second half of the day Sunday. Highs in the upper 70s.

Today: Once this line of non-severe storms exits this morning, the clouds will thin and the atmosphere will become unstable. The higher the instability, the better the chances of pop-up storms to develop (very similar to yesterday). Below is Futurecast at 2 and 6 p.m.

Once storms fire-up, they’re capable of reaching severe limits with the primary threat being damaging winds. Hail and heavy rain leading to localized flooding is also a concern. The Storm Prediction Center placed the entire Wabash Valley under a ‘slight risk’ for severe storms for both today and tomorrow.

Tonight: An upper level wave will prompt another round of storms during the overnight. Temperatures will drop back into the upper 60s, close to 70°. Here’s 2 a.m. on Futurecast:

Saturday: Thunderstorms will fire Saturday around midday with an approaching cold front. Again, storms will be strong to severe. The threat for these stronger storms continues through sunset Saturday. Here’s noon and 7 p.m. on Futurecast:

Extended Outlook: Severe threat comes to an end shortly before midnight and conditions improve by Sunday. Temps will be a tad cooler with highs in the lower 70s to end the weekend and start next week.

The MCV (mesoscale convective vortex) or ‘ group of storms’ that is back to our west has the potential to redevelop and intensify this afternoon with the current conditions outside. (Warmer air/unstable atmosphere). This will bring the chance for severe storms into the Wabash Valley later this afternoon into tonight. Below is Futurecast’s prediction of the storm location around 8 p.m. EDT.

Multiple lines or clusters of storms could develop during the second half of the day today. Should storms reach severe limits, the main threats are damaging winds and large hail. Frequent lightning is a  threat in any thunderstorm.

Be ‘weather aware’ throughout the next few days as severe storms are possible through Wednesday. Storm Team 10 will be giving continuous updates with the changing weather situation and will keep you posted should threatening weather arise. Stay tuned both on-air and online at www.wthitv.com

One inch of rain was measured by an automated weather station in Washington.  Radar estimates up to three inches of rainfall at some locations in Daviess County.

There has also been radar estimated rainfall totals in an upwards of  three inches in portions of Lawrence County, IL where there is also an urban and small stream flood advisory in effect until 1:30 p.m. CDT.

A Flash Flood Warning remains in effect for southern Knox-Daviess-Martin counties until 4:30 p.m. EDT. Several reports of heavy rain and flooded roadways have come in from those locations including the cities of Vincennes, Shoals and Washington.

No other severe weather warnings are in effect at this time.

Tonight: Thundershowers will become less numerous during the overnight. Temperatures stay mild with overnight lows near 60°.

Tomorrow: Scattered rain and thundershowers will be around again on Friday, but temps will be a bit cooler with highs in the lower 70s.

Extended Outlook: Dry and cooler conditions move in for Mother’s Day weekend. Highs will be near 68 Saturday, only 60 on Sunday with overnight lows in the upper 30s Sunday night into Monday morning.

Tomorrow:  By tomorrow morning, the rain will subside to the south and west. The best chance for rain stays across southwestern portions of the Valley. Temperatures turn much cooler, highs will only be in the lower 60s.

Headed to Indy for the 500 Festival Mini Marathon tomorrow? Tiny chance for rain, but otherwise looks cloudy and mild.

Sunday: We’ll continue to see lingering rain showers through the second half of the weekend. Again, not looking for an all day wash out, but there will be periods of rain around on Sunday. Highs rebound slightly into the mid 60s.

Extended Outlook: Drying out by Monday. Next week is looking relatively dry and mild. Temperatures return to the lower 70s to start off our work week and will rebound to the mid to upper 70s by the end of the week.

The most recent example is the flooding that has painted a calamitous picture across the Valley. I can talk about Flood Warnings, river levels and see pictures of flooding from the weather center at WTHI, but the impact of flooding was really put into perspective when I  and other News 10 staffers joined the sandbagging efforts of a local community yesterday.

Not only did I meet and have good conversations with members of this community, but I also met people from out of the area who heard about the flooding on the news and wanted to come help out. By the time the sun started to set (around 8:30 eastern time), I heard a familiar story by so many. “I’ve been out here since 10 a.m.,” ….”I heard about this and came as soon as I got off work,” …”I’ve been out here working all day”. It was phenomenal, and nightfall didn’t seem pose a stopping point for these folks.

Covered in dirt, tired with achy hands, arms and backs, men and women of all ages continued shoveling sand into white bags and tossing them into the backs of donated pick-up trucks. All that doesn’t seem so bad when you know your efforts could save homes, businesses or the property of others.

So I just want to say thanks again to everyone who took time out of their day to help “a community”, whether it be your own or someone else’s.

Timing & Amounts… Rain looks to move in mostly after midday today and become more widespread through this evening. Up to a quarter inch of rain is possible with locally higher amounts within storms. Severe storms are not expected. However, the rain showers and storms will continue through the overnight hours adding three quarters to one inch of additional rainfall.

Tomorrow: Highs will only be in the lower 50s Wednesday, rain showers come to an end early and skies turn partly cloudy.

Extended Outlook: We’ll stay dry and cool through the end of the week with highs in the mid 50s Thursday and back into the lower 60s by Friday. Rain showers return Saturday.
