Alberto's Impacts Start TODAY: Memorial Day Hour By Hour

All is quiet, for now, in Kentuckiana. It is warm and humid again with a mix of sun and clouds. However, once again, we have a chance for showers and storms. But these are being brought to us courtesy of Subtropical Storm Alberto. If you look below, you can see there is a lot of moisture of ahead of the main circulation and that outermost band will make it to our neck of the woods today. That means our shower and storm chance is not just heat driven and will not wrap up when the sun sets. It actually increases.

Our shower and storms chances only increase this week from the remnants of Alberto.

Memorial Day Hour By Hour: 

For any of your outdoor plans and events, the first half of the day looks to be dry. Showers and storms return by mid afternoon. I have about a 20% chance for showers and storms by 5 pm, but increase that to 40% by 8 pm and 50% by 11 pm. Highs will be in the mid to upper 80s, but with sticky dew points, it will feel even warmer, in the low to mid 90s.

The rest of this morning and early afternoon look dry.

By mid to late afternoon (2-4 pm), we will introduce more shower and storm chances. Starting off isolated to scattered at first. Also, the more south you go, the better chance you have for showers and storms. Heavy downpours are once again likely. There are also some flooding concerns (especially in areas that saw heavy rain yesterday). Gusty winds and frequent lightning are also on the table.

Showers and storms become more numerous with time and move more north. They will be moving from east to west as Alberto churns in a counter clockwise rotation. I have increased our rain chance for tonight (since this weekend and this morning) as the latest data came in, but the good news is that most of our events will be over at this time. It appears we could have decent coverage in the southern half of our viewing area this evening and tonight from the northern edge of this outer band associated with Alberto.

This looks like it could continue through tonight and through a portion of the overnight, before tapering off tomorrow morning. Another round of showers and storms will arrive on Tuesday, as Alberto's remnants heads toward Kentuckiana and more of the area will feel impacts.

Speaking of Tuesday, heavy rain is likely to fall and severe weather is also possible. The heaviest rain will be along and west of Interstate 65 in central Kentucky and southern Indiana. 1 to 2 inches of rain is expected Tuesday through early Wednesday with locally higher amounts possible. Flash flooding is a concern. Severe weather is also a possibility because we will be on the NE side of the low when it passes through, which is notorious for spin ups.
