7/18 - 12pm - Heat, Storms on the Way this Week
Many areas across Louisville saw heavy rain yesterday as scattered storms slowly made their way through the area. A setup like that will likely happen this afternoon as well with storms again coming from the north. Any chance of severe storms will stay to our north as the ingredients for this will be in better supply. Look for a high just over 90 degrees this afternoon in the city and a degree or two lower in the suburbs.
Tomorrow will be a different story. A small upper-level disturbance will be swinging our direction around a high centered in the Midwest. This should spawn an MCS (Mesoscale Convective System - a big complex of storms) in the afternoon that will move our way from the northwest. The whole evolution of the MCS and exactly who it will affect most is still murky at this point, but it seems the parameters for severe weather will be in place and the SPC has issued a 15% Slight Risk for the region. Damaging winds from bowing segments and even a few spin-up tornadoes are possible with this MCS tomorrow, so be on the lookout for warnings as they're issued.
