SHORT TERM
(Today through Sunday)
Issued at 1235 AM CDT Sat Jul 27 2024
Water vapor imagery this morning shows the broad upper-level trough axis finally shifting to the east as ridging begins to build to our south. Still plenty of moisture out there though with the PWAT on yesterday evening's sounding coming in at 1.76 inches.
Would expect that to decrease on today's soundings though.
Meanwhile, closer to the surface, dewpoint depressions are once again small at or less than 2 degrees. This is again leading to the development of patchy fog across the area as has been the case the past several mornings.
Thanks to the ridging building overhead today, storm chances will decrease today. They won't be zero as there's nothing to completely get rid of our moisture, but coverage should be less compared to previous days. The ridge will be short lived though as a trough moves across the Midwest. This trough will bring more storm coverage as we head into the new work week. Localized flooding will continue to be a concern, especially in heavier downpours.
LONG TERM
(Sunday Night through next Saturday)
Issued at 1235 AM CDT Sat Jul 27 2024
Troughing over Middle TN will continue to impact the area on Monday. PWAT values ranging from 1.5 to to 2 inches are possible during this and moving forward for the rest of the week. The troughing won't last long as a high pressure develops over the southern plains. With this ridging, summertime pop-ups are likely each day. Heat and dewpoints will continue to climb through out the week, leading to heat indices nudging into the 100-110F range. Another upper-level trough may move into the area late next week, but confidence is low in timing and strength of this system.
