Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 AM EDT Mon Oct 20 2025 Valid 12Z Mon Oct 20 2025 - 12Z Wed Oct 22 2025 ...Low pressure system to bring locally heavy rain and gusty winds for the Northeast today... ...Windy, colder, and unsettled weather to spread across the northern tier states for the next couple of days... ...Unseasonable October warmth cross the southern Plains to start the week with highs climbing well into the 80s and 90s... An active weather pattern is in progress across the nation to start the new week. This active weather pattern is spearheaded by an intensifying low pressure system that is moving swiftly north of the Great Lakes into southern Canada this morning. Meanwhile, a potent cold front trailing south from the cyclone center will interact with an upper trough that is dipping into the Appalachians, leading to the development of another low pressure system. This new system is forecast to bring a round of rain, locally heavy at times, and possibly embedded with a few thunderstorms across New England today. In the wake of this system, breezy, cooler, and drier conditions will be filtering into the eastern U.S. through tonight before temperatures quickly rebound on Tuesday ahead of the next low pressure system approaching from the northern Plains. The aforementioned low pressure system over the northern Plains is currently in the developmental stage. This system is forecast to expand in size and move eastward to reach the Great Lakes on Tuesday. Mountain snow across the northern Rockies on the backside of this system is expected to taper off today. Meanwhile, areas from the northern High Plains eastward to the Great Lakes can expect a period of rain to accompany the passage of the low, followed by colder and windy conditions especially across the northern Plains through tonight. The windy conditions will spread east into the upper Midwest and Ohio Valley Tuesday into Wednesday along with a cold rain falling throughout the Great Lakes. Scattered areas of rain will also reach the Mid-Atlantic and especially New England overnight Tuesday into Wednesday morning. To the south of this system, brisk winds descending the southern Rockies will make for a very warm afternoon across the southern Plains on today where highs are forecast to reach well into the 80s and 90s, which is roughly 10 to 20 degrees above normal for mid to late October. These temperatures will also be high enough to challenge some daily records. Dry weather will remain the rule across the Southwest and the Four Corners with a gradual warming trend spreading further northward into the Rockies through midweek. Meanwhile, chance of showers and thunderstorms will gradually decrease across the Sunshine State as the trailing cold front weakens with time.
