060 FXUS01 KWBC 131856 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 255 PM EDT Mon Jul 13 2026 Valid 00Z Tue Jul 14 2026 - 00Z Thu Jul 16 2026 ...Anomalous heat and humidity continue across the northern Plains to the upper Midwest, spreading into the Northeast by Tuesday... ...Threat of heavy rain abates across the southern Appalachians to the Carolinas; significant heavy rainfall likely over the Hill Country and Big Bend regions of Texas... A strong upper-level high, responsible for several all-time high temperature records in the West yesterday, is forecast to build eastward across the northern tier states over the next few days. This will yield record-breaking high temperatures of 95 to 105 across the northern Plains and Midwest through midweek, which also spreads over the Great Lakes and Northeast on Tuesday. Extreme Heat Warnings remain in effect across a large portion of the Great Basin through the northern Plains as Heat Advisories are posted for areas farther east into New England. If you will be situated within any of these areas forecast to experience extreme heat, stay hydrated, take frequent breaks, and limit outdoor activities if possible. A cold front will draw slightly cooler air eastward from the Pacific Northwest into Montana and North Dakota over the next couple of days, dropping high temperatures into the upper 80s and 90s. South of this anomalous upper high, a front is forecast to remain nearly stationary through the southern Plains, the Deep South and the Southeast. Upper-level disturbances will then interact with the wavy stationary front to produce repeated rounds of showers and thunderstorms across this corridor of the southern U.S. Meanwhile, the heavy rain threat across the southern Appalachians and Southeast will gradually abate as drier air filters in from the north. Near the western end of the front, a significant heavy rainfall event is expected across the Texas Hill Country and Big Bend over the next three days as thunderstorms repeatedly focus over this region. The latest rainfall forecast calls for storm total rainfall amounts of 6-8" through Wednesday evening, which could lead to dangerous flash flooding as soils in the area become increasingly inundated. Meanwhile, the forecast remains on track for an influx of monsoonal moisture to drive an uptick in daytime thunderstorms over portions of the Great Basin and Intermountain West. A few instances of flash flooding and severe weather are possible in the strongest storms through midweek. Asherman/Kong Graphics available at https://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php $$
