6/30 - 9am - Slight Storm Chance

Looks like this northwest flow due to an area of low pressure in the Great Lakes could bring us a very small chance for some storms this afternoon. Most places around the area will not receive rain, so the rain-free week continues for a majority of the area. Another slight chance for storms exists tomorrow, but that will be it until Saturday(July 4th). This northwest flow will really take down temperatures over the next few days, with a possibility of highs dipping into the upper 70's tomorrow. We'll recover back into the mid 80's for the rest of the week, but the northwest flow will take us in to unseasonably cool territory. Our average high for this time of year is 86 degrees.

6/29 - 4pm - Rain-Free for Nearly a Week!

We're getting ready to close out the second wettest June on record in Louisville, but you'd never know it by looking at the forecast. This pattern where we have the ridge to our west is keeping all precipitation to our north, and that should continue until at least Saturday with highs in the mid 80's. By then, a low passing to our south may generate some showers and storms up this way. According to the long-range GFS, it looks like we'll pick up our dry pattern right where we left off by then.

6/28 - 10:30am - Dry and Cooler

This should be the last day in the 90's for a little while and we should remain dry this week. A cold front that moved through this morning, accompanied by no rain, will lower temperatures into the mid 80's this week. Any disturbances will stay just to our north thanks to ridging in the west, so we should see clear skies until at least next weekend.

There may be a stray shower this morning or early afternoon due to this cold front still being in the area, but chances look slim.

6/27 - 3:30pm - New Video Forecast

Today will be a scorcher, but next week looks a bit tamer in terms of temperature. After a few scattered storms on Sunday morning, the rest of the week will see dry weather and temperatures in the mid 80's.

6/26 - 10am - A Temporary Reprieve

A line of storms that went through last night gave us a soaking and a good lightning show. There could be some pop-up scattered storms later this morning and this afternoon, but the main action is well to our south now. Some of these storms could get severe, so the SPC has put us in a SLIGHT Risk for severe weather today:



Dry and clear conditions are expected until Sunday, when we'll have another line of storms come through during the late afternoon or evening. The dry and clear weather will resume after Sunday, but luckily temperatures will dip down into the 80's next week.

6/25 - 1:30pm - Scattered Strong Storms

More heat is on the way with a high somewhere between 92 and 93 today. Looks like we're going to see some scattered strong storms this evening as a cold front comes through. West surface winds and light shear should prevent them from becoming too bad, but there could be a few severe storms with wind and hail.

More showers and storms will roll through tomorrow, but none are expected to be severe. Saturday looks dry and very hot (mid 90's), but scattered showers and storms will make another appearance on Sunday. Once the rain on Sunday is finished, we should stay clear and dry with highs in the mid to upper 80's next week.

6/24 - 3pm - Storms Tomorrow, Maybe Severe?

We've yet to break 90 today, but we're almost there at 88 degrees. Temperatures around the area should top off at around 92 this afternoon. The SPC has issued a SLIGHT Risk (15%) for severe weather tomorrow for us and areas to our north:


Instability will be a little higher than usual tomorrow and there will be ample moisture to support thunderstorm development. I'm not impressed with winds coming off the models right now, so a tornado threat looks unlikely at this time. A bit of the jet stream will be coming down from the north tomorrow, so we'll have to see exactly what this does in the morning. If a line of storms forms and comes through here in the morning, our severe threat will be limited or nonexistent. If not, and we maintain clear skies throughout the morning and afternoon, then the severe threat would be elevated quite a bit. It should become clear by early tomorrow how bad the storms will be.

Friday and Saturday will be steamy again, but at least there won't be any rain. Thunderstorms could return to the area on Sunday, but the rest of next week looks pretty dry!
