A frontal boundary extends from the Rockies through the southern Plains and eastward into the Southeast. This will act as a focus for rain/thunderstorms over the next couple of days as it separates a warm/humid air mass closer to the Gulf Coast from a more temperate air mass over the Mid-South. Rounds of rainfall over already soggy areas may lead to flooded roads and/or rivers -- Turn around. Don`t drown! There is a Moderate Risk (level 3 of 4) for excessive rainfall and flash flooding over northeastern Oklahoma into southwestern Missouri and northwestern Arkansas (Ozarks region) on Sunday. In addition, severe weather is possible along and south of the frontal boundary, especially over Oklahoma into north Texas. The Storm Prediction Center has issued an Enhanced Risk (level 3 of 5) for severe weather there, with large hail and strong, damaging winds the main threat. Tornadoes are also possible. Over the Northeast, a slowly departing system will maintain a cool pattern over the region for the Holiday weekend, but temperatures will moderate into Monday. Still, highs will only be in the 50s/60s to the north and low-mid 70s over most of the Mid-Atlantic (south of I-76). Isolated afternoon showers Sunday will decrease further on Monday as high pressure approaches from the Great Lakes. Over the West, a generally dry and warm Sunday will lead to increasing clouds, rain showers, and cooler temperatures by Monday west of the Continental Divide. Temperatures will rise well into the 80s over the interior West on Sunday but will remain much cooler along the coast. The approaching cold front will come ashore Sunday evening with some showers for the lowlands that clear areas west of the Cascades by Monday afternoon.
