640 FXUS01 KWBC 060748 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 346 AM EDT Mon Oct 06 2025 Valid 12Z Mon Oct 06 2025 - 12Z Wed Oct 08 2025 ...Heavy rain and flooding potential across parts of the Mid-South and Ohio Valley... ...Above average warmth for the Great Lakes and Northeast today with possible record high temperatures in New England... A strong cold front will stretch across the Midwest to southern Plains ahead of an upper-level trough, and will slowly march eastward over the next couple of days. Above average moisture from the Gulf is expected to stream northward and pool near the front, providing a focus for heavy rainfall across parts of the Lower Mississippi Valley, Mid-South, and Lower Ohio Valley today into tonight. A Slight Risk (level 2/4) of excessive rainfall causing scattered flash flooding is in place for these areas. As the front moves, the risk of heavy rain and flash flooding should shift slightly eastward on Tuesday. The greatest threat will cover Kentucky in particular, with another Slight Risk in place. Areas of 3 to 5 inches of rain are possible. Some rain is forecast to stretch northward into the Great Lakes today and Northeast and Mid-Atlantic on Tuesday, but not quite as heavy as farther south. Elsewhere, showers and thunderstorms could continue across the central Gulf Coast today and Florida over the next couple of days, with some localized flash flooding particularly in urban areas. Meanwhile, today and especially by Tuesday, scattered thunderstorms could form over New Mexico and lead to isolated flash flooding particularly in sensitive areas like burn scars. The potent cold front will be a dividing line between cooler than average temperatures to its west and warmer than average temperatures to its east. Unseasonably warm temperatures with highs in the 80s will be widespread today across portions of the Midwest into the Great Lakes and Northeast, and a handful of record highs could be tied/set particularly in New England. By Tuesday the Ohio Valley and Great Lakes should cool closer to normal behind the front, but the Northeast is likely to remain warm. Meanwhile, below normal temperatures (especially for highs) are likely across the Intermountain West, and the coolest anomalies of 15 to 25 degrees below normal are forecast for the central High Plains, where highs are forecast to only reach the 50s. On Tuesday the cool air should dive south a bit into the south-central Plains, yielding highs in the 60s. Chilly low temperatures have have prompted Freeze Watches/Warnings and Frost Advisories this morning scattered through the Intermountain West and north-central U.S., and freezing temperatures could remain a concern into Tuesday morning for parts of Wyoming into northwestern Colorado.
