605 FXUS01 KWBC 012029 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 427 PM EDT Thu Oct 01 2026 Valid 00Z Fri Oct 02 2026 - 00Z Sun Oct 04 2026 ...Excessive rainfall potential lingers over the Southern Plains through Friday before shifting into the Southeast and Gulf Coast this weekend... A slow moving cold front will focus showers and thunderstorms along its boundary from South Texas up through the Midwest and into the Lower Great Lakes tonight. Storms will persist over the southern and eastern Texas on Friday due to the quasi-stationary nature of the aforementioned front, though, the northern section of it continues to move east spreading scattered showers and thunderstorms into the Ohio Valley, Northeast and Mid-Atlantic. Subtropical moisture originating from the Caribbean will flow northward and interact with a weak convergence zone along the Gulf Coast. This will lead to some thunderstorm and heavy rainfall potential on Friday. The slow moving front finally arrives over the Southeast and Gulf Coast by Saturday, when it will combine with the aforementioned moisture to generate heavy to excessive rainfall from South Texas to the Carolinas. Elsewhere, another low pressure system will swing south into the northern tier states on Saturday, generating additional showers across the Dakotas and Upper Midwest/Great Lakes. Persistent ridging over the West will promote above average temperatures for much of the region through early next week. Minimum temperatures in the low to mid 70s will provide little to no overnight relief to those without adequate cooling or hydration. Extreme heat warnings are in effect for parts of SoCal from the San Diego Metro to the Los Angeles Metro for the next several days. Heat advisories are in effect for much of Central California west of the Sierra this weekend. Kebede Graphics available at https://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php $$
