Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 337 AM EDT Sat Jul 03 2021 Valid 12Z Sat Jul 03 2021 - 12Z Mon Jul 05 2021 ...Excessive heat to continue across the Northwest and Northern Plains... ...Showers and thunderstorms likely along a frontal boundary draped across the Gulf Coast with monsoonal moisture likely across the Southwest and southern High Plains... ...Slight risk for severe thunderstorms from northeast Colorado into western Nebraska... Excessive heat is expected to continue through the Holiday weekend across the Northwest and Northern parts of the country. Saturday should be the hottest, with daytime highs well into the 90s or low 100s for many from the northern Great Basin into the Northern Plains and Upper Midwest. A handful of daily record highs are possible across these regions as well on Saturday. By Sunday and Monday, the heat should subside somewhat, however temperatures are still expected to be well above normal for some locations which would only prolong the heat stress. Excessive heat warnings and heat advisories remain in effect for parts of the Northwest and eastern Montana. Showers and thunderstorms are likely along a nearly stationary frontal boundary which should settle along the Gulf Coast through much of the period. Moderate to locally heavy to excessive rainfall is possible from northern Florida to eastern Texas. Farther west, monsoonal moisture will bring diurnally driven showers and storms into parts of the Southwest and southern High Plains each day. Again, there is a threat for moderate to locally heavy rainfall and isolated flash flooding. Elsewhere, scattered showers and storms will extend northward into the central High Plains and the Dakotas along a slow moving warm front and ahead of a cold front dropping into the Northern tier states. SPC highlights a small area from northeast Colorado into Western Nebraska within a slight risk for severe weather. Across the Northeast, unsettled weather will continue as a surface low deepens offshore. While the Northern and Western parts of the country continue to bake, the remainder of the U.S. should be more comfortably near or below normal through the weekend. The greatest below normal anomalies should center across parts of the southern High Plains, and especially the Northeast on Saturday where daytime highs 10 to 20 degrees below normal are possible with daily record low max temps challenged. The southern and eastern states should warm up by the Fourth of July holiday with much above normal temperatures seeping into the Midwest/Ohio Valley and Mid-Atlantic states by Monday.
