Issued at 934 PM EDT Mon Jun 24 2024

Sfc high pressure overhead will retreat east into the Appalachians overnight, but we`ll maintain seasonal temps and less muggy dewpoints into Tuesday morning. Look for hot return flow to set up out of the SW mid/late morning. Convection will develop over northern Illinois and Indiana in the late morning or early afternoon hours, but that will struggle to advance southward into quite a capped atmosphere. Will need another source of lift which won`t come until at least Tue evening. Current forecast remains well on track.

Issued at 310 PM EDT Mon Jun 24 2024

High pressure over the upper Ohio Valley and a mostly dry atmosphere will lead to clear skies and light winds for southern Indiana and central Kentucky tonight. Low temperatures should once again be in the 60s, and some valley fog will again be possible in the Lake Cumberland region by dawn.

The heat and humidity will turn back on tomorrow as return flow brings warmth and moisture to the region. Highs are expected to be in the lower and middle 90s. Dew points west of I-65 will climb back up to around 70 degrees, creating peak afternoon heat index values around 100.

Can`t rule out isolated thunderstorms by late Tuesday afternoon, possibly on outflow from earlier convection to our north. Synoptic scale deep layer shear will be very weak, but there will be plenty of instability and enough moisture to support storms if any can get going, especially in southern Indiana.

Issued at 310 PM EDT Mon Jun 24 2024

The cold front will approach from the northwest Tuesday night and move through the region sometime around Wednesday afternoon, though there will likely be myriad convectively induced boundaries in the area Tuesday night and Wednesday as well. There will be plenty of moisture available to support multiple rounds of showers and storms.
How much instability will be present is tough to nail down given the presence of widespread clouds and occasional rain, but the SPC Day 3 MRGL looks good for some storms producing locally gusty winds with the heavier downpours. Models have been quite consistent with this system and there is reason to be cautiously optimistic that many spots can receive beneficial rainfall with it mid-week.

Thursday and Friday look dry and very warm as high pressure advances from the Great Lakes to New England. A large upper ridge is expected to develop over much of the southern half of the country by late week, with afternoon temperature readings into the lower and middle 90s by Friday.

Shower and storm chances return to the forecast this weekend as the next cold front pushes through, with the best chances of rain Saturday night into Sunday morning. While some stronger storms can`t be ruled out, the main impact of this system appears to be another chance for beneficial summertime rains. It will be interesting, though, to see just how far south the front can make it given the moderately strong 5H ridge that is progged to set up for the southeast U.S. Friday-Tuesday. Speaking of which, after a hot day on Friday another hot one is expected for Saturday ahead of the front and under the edge of the upper ridge, with afternoon readings currently pegged in the middle 90s.

Issued at 127 AM EDT Tue Jun 25 2024

VFR conditions are expected to mainly prevail through this TAF cycle. The only caveat to this will be for some scattered t-storm activity at the I-64 corridor sites later tomorrow evening. Included a Prob30 mention with this issuance to account for that. Otherwise, look for a quiet early morning and much of the day with only a few afternoon cu and upper clouds to speak of at times. Light SE winds early this morning will give way to more steady SSW winds tomorrow.
A few gusts up around 15 to 20 mph are possible as we get into the afternoon hours, especially at SDF/LEX.
