.SHORT TERM... (Rest of today through Sunday) Issued at 1145 AM CDT Sat Oct 4 2025
A surface and upper level ridge centered along the Mid Atlantic coast will keep our wx nice and dry through the rest of the weekend. Daytimes will be sunny and very warm, perhaps touching 90 in some spots Sunday. Tonight will be clear and seasonably cool with lows mostly from 55 to 60. A few patches of late night fog will be possible.

.LONG TERM... (Sunday Night through next Saturday) Issued at 1145 AM CDT Sat Oct 4 2025
Departure of high pressure to the east will allow southerly flow to increase, bringing a surge of Gulf moisture Sunday night and Monday. Scattered showers will develop, especially west of I-65. Models vary with how vigorous lift will be during this time, thus models vary considerably with rainfall coverage and amounts. Generally, the rain looks scattered with amounts mostly less than one quarter inch. However, a few ensemble members are showing pockets of 1 inch rainfall amounts in our far west counties. This potential for 1 inch of rain through Monday is less than 20 percent.
Rain chances will increase Monday night through Tuesday as a trough approaches from the west and atmospheric instability increases. Precipitable water values will climb over 1.7" which is above the 90th percentile for the date. Lift does not look very strong or focused, but with good moisture depth and instability through the column, some areas, especially west of I-65, could have decent amounts of rain approaching one inch on Tuesday. Some embedded thunder will be possible, but the severe threat is low.
Over the past few days, models have been inconsistent with the upcoming rain chances, but the latest trends have been wetter. The large-scale pattern suggests some spots will have decent rainfall amounts while others do not receive as much. To all those who want significant relief from the dryness, may the odds be ever in your favor.
After the front, cooler air will move in for pleasant conditions late week. The pattern looks mostly quiet, but a disturbance will bring low chances for scattered showers Thursday into Friday.
