Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 329 AM EDT Mon Jun 9 2025 Valid 12Z Mon Jun 9 2025 - 12Z Wed Jun 11 2025 ...Active severe weather setup from the southern Plains to the Mid-Atlantic through Tuesday... ...Stifling heat dome to build in throughout much of the West and the western Gulf Coast; hottest temperatures compared to normal centered over the Northwest... The main thing making weather headlines over the next couple of days will be the potential for strong to severe thunderstorms to develop across portions of the Deep South and extending northward to the central Appalachians on Monday. The Storm Prediction Center has a Slight Risk of severe thunderstorms from near New Orleans to western New York. There will likely be scattered multi-cell clusters and some supercells, with damaging winds and large hail the primary threats, and some tornadoes are also a possibility. An approaching cold front from the northwest will intercept a warm and unstable environment ahead of it, and fuel the development of intense convection going into the afternoon and evening hours. In addition to the severe weather threat, periods of heavy rainfall may lead to some instances of flash flooding across portions of Pennsylvania and New York, as well as portions of the Gulf Coast region, with some areas potentially getting 1 to 3 inches of rain. Another area of stormy weather is expected to be across western Texas and eastern New Mexico on Monday, where a broad Marginal Risk and embedded Slight Risk of severe weather is valid, but not as widespread as what happened Sunday evening across Texas. Additional areas of strong thunderstorms and heavy rainfall can be expected across southern Texas to Louisiana on Tuesday, and also near the East Coast as the cold front slowly approaches and then exits the coast by Wednesday morning, followed by drier and slightly cooler conditions for the middle of the week. Elsewhere across the Continental U.S., widespread anomalous heat will continue to affect interior portions of the Pacific Northwest through Tuesday with heat advisories in effect from northern California to eastern Washington and northern Idaho, and daily record highs are likely for some areas. It will also continue to be uncomfortably hot and humid from Texas and extending east across the Gulf Coast, with high dewpoints and temperatures in the upper 80s to middle 90s making it feel over 100 degrees at times during the afternoon hours, and remaining quite humid overnight. Air quality alerts are in effect across portions of the Northeast as wildfire smoke from distant Canadian wildfires continues to infiltrate those areas.
