A wet and active weather pattern will persist across central and south-central sections of the country through early next week. A stationary boundary extending from the central Rockies through the central Plains and into the Ohio/Tennessee valleys will be the focus for multiple rounds of showers and thunderstorms. This evening and overnight, a few thunderstorms may turn severe across the central and southern High Plains. Damaging wind gusts and large hail are the main concern, with isolated tornadoes possible throughout the central High Plains and southwest Texas. Downpours could lead to isolated flash flooding across central and eastern Kansas, as well as south-central Texas tonight. Sunday and Monday will feature similar weather hazards across the same region. The Storm Prediction Center has issued a Slight Risk of severe weather on both Sunday and Monday that includes portions of the central High Plains and southern Plains. With the ongoing thunderstorms, flash flooding will remain a possibility across these regions while also extending into the Middle Mississippi Valley as well. WPC has issued a Slight Risk of Excessive Rainfall for Sunday that stretches from central Missouri to north-central Texas. Elsewhere, scattered showers and thunderstorms will also be found across southern Florida, the Ohio Valley, Mid-Atlantic, and Northeast between tonight and Monday. High temperatures are forecast to run well above normal across the Northern Plains, Upper Midwest, and northern Great Basin. Highs into the upper-70s and 80s will make it feel more like June and potentially worsen extreme drought conditions throughout in the Northern Plains. Meanwhile, gusty winds and low relative humidity will create critical fire weather this evening across southern Nevada, southwest Utah, and northwest Arizona. Red Flag Warnings have also been issued for this area. Snell Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
