304 FXUS01 KWBC 120801 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 401 AM EDT Mon Oct 12 2026 Valid 12Z Mon Oct 12 2026 - 12Z Wed Oct 14 2026 ...Heavy rainfall continues over the Great Basin and Southwest today; wet weather moves into the Plains this week... Unsettled weather will continue over the Great Basin and Desert Southwest to begin the work week as a slow moving cold front and lingering tropical moisture remain overhead. Much of the region can expect downpours throughout today, with a general focus over favorable terrain from Utah to Arizona. Scattered flash flooding is possible as today's round overlaps with areas impacted from heavy rainfall over the last few days. The approach of a closed upper-low from the Northwest will also lower snow levels enough to support snow in the peaks of the Shoshone and Monitor Range in Nevada and Utah Wasatch. This upper-low will maintain the wet pattern in the West tomorrow, which could lead to isolated flash flooding in Utah. By then, however, the focus for showers and thunderstorms will begin to move toward the Central and Southern Plains as another slug of moisture interacts with a slow moving cold front and sharpening dryline. Scattered severe weather is possible from Kansas City to Lubbock tomorrow ahead of the cold front, and on Wednesday, rainfall amounts upwards of 2-3" are possible from western Missouri to the Texas Big Bend, where a Slight Risk of excessive rainfall is highlighted. Meanwhile, to the east, a developing frontal wave will spread showers and thunderstorms across the Northern Tier from the Upper Midwest to New England tomorrow and Wednesday. No excessive rainfall threat is anticipated with this activity, although accumulating snows are possible in the Boundary and Blue Mountains of Maine. A temperature dichotomy will remain across the country through mid-week. Well above average temperatures are forecast to develop over much of the Central and Eastern U.S., with highs into the 80s and even lower 90s for portions of the Plains and Midwest. There will likely be some daily record highs that will be tied or broken. Much colder temperatures are expected across the West under the upper-low, with highs generally in the 40s and 50s across the Intermountain West. Eventually, portions of the Northern Plains, Upper-Midwest, and New England can expect a notable temperature change over the next 48 hours as the front moves southward through the area.
