KEY MESSAGES

- Dry conditions continue through Friday along with above normal temperatures in the 80s. A few locations may approach 90 degrees on Friday, threatening daily record highs. Low relative humidity may produce an elevated wildfire danger risk.

- The remnants from Hurricane Isaias will impact our region this weekend. Widespread soaking rains appear to be the greatest impact, but gusty gradient winds are also possible. Peak timing for rain is Saturday into Saturday night, possibly lingering into Sunday morning.

DISCUSSION

Issued at 1250 PM CDT Thu Oct 8 2026

For today and into tomorrow our weather remains mostly dictated by an upper level ridge over the plains and surface high pressure over the Appalachians. Tomrorow's conditions look similar to today with temperatures perhaps slightly warmer and a moderate east to southeast wind as the surface pressure gradient slowly starts to react to the presence of Hurricane Isaias. Relative humidity values are forecast to fall to 20 to 30 percent in the afternoon with east winds at about 5 to 8 mph. These are elevated fire danger conditions from a purely meteorological standpoint although fuels are not quite yet fully receptive. Highs on Friday look to approach daily records.

Hurricane Isaias is on-track this afternoon. Hurricane Hunter aircraft show a steady increase in intensity, in line with previous forecasts and the storm is projected to cross the AL/FL coastline Friday night. A shortwave trough presently over the Texas Big Bend interacts with the cyclone as it moves onshore helping it accelerate and max a quick extra-tropical transition. Favorable jet-level lift ahead of the system should lead to rainfall starting Saturday morning across most of the area with the center of the cyclone pulling northwestward into west Tennessee by midday. The peak of any stronger winds should be Saturday afternoon mainly across western Kentucky with gusts 25-30 mph currently forecast. Storm total rain of 1 to 1.5 inches across western Kentucky decreasing to 0.5 to 0.75 inches further north and west remains on track. This should not be enough to cause flooding issues given the antecedent conditions. Hodographs/shear are favorable for tornadoes but for now instability appears very limited with surface temperatures in the lower 60s and dewpoints in the upper 50s.

The more benign passage that only results in impacts to planned outdoor events with a steady most of the day rain is about the 80-85% confidence scenario. The contingency would be if the storm were to rapidly intensify well-beyond the current forecast intensity prior to landfall, which can happen with these semi- sheared storms that end up utilizing the favorable outflow channel rather than be sheared apart by the southwesterly winds aloft north of the storm. This seems less likely as time progresses but we will remain alert to the possibility. If the storm were to end up being stronger at landfall then the risk of flooding rains, stronger winds, and at least some tornado threat would be higher.

Ridging builds back in behind the departing tropical remnants with dry and relatively warm conditions forecast through at least Tuesday. Wednesday-Thursday a trough begins to approach from the west and may lead to increased shower and storm chances but the upper ridge that establishes over Georgia looks like it could be strong enough to hold everything back through the end of the work week.
