Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 358 AM EDT Wed Jun 17 2020 Valid 12Z Wed Jun 17 2020 - 12Z Fri Jun 19 2020 ...Cool, wet, and dreary weather continues over the Mid-Atlantic and Carolinas, showers and storms likely in central and southern Florida... ...Cool and rainy weather in the northern Rockies along with another round of late-season high-elevation snowfall... ...Hot conditions through the North-Central U.S.; severe storms in the northern Plains and Upper Midwest; fire weather danger in the Southwest and central High Plains... The upper-level low responsible for the soaking rainfall in the Carolinas the last several days will inch its way north today. The axis of heavy rainfall also pushes north into the Mid-Atlantic today. Rainfall totals in western and central Virginia can expect between 1 to 2 inches of rainfall through Friday morning, with localized amounts as high as 3 inches in the Blue Ridge mountains. As the upper low gradually weakens on Thursday, showers and storms should become more scattered in nature and cover more real estate as the threat for showers and portions reaches the eastern Ohio Valley and northern Mid-Atlantic. Considerably cooler temperatures look to stick around from Georgia to Maryland today with a slight warming trend taking shape by Thursday. Farther south, showers and thunderstorms will fire over much of central and southern Florida on Thursday and persist into Friday morning. The summer solstice is this Saturday but someone forgot to tell that to Old Man Winter as heavy mountain snow piles up over portions of the northern Rockies this morning. This is due to an intense upper low swinging through the region today that is accompanied by temperature anomalies ranging between 15 to 20 degrees below normal throughout the region. Winter Storm Warnings have been issued for parts of north-central Idaho and southwest Montana along with some frost advisories in northern Nevada, far northern California, and south-central Oregon. The valleys and lower elevations of the northern Rockies and High Plains can expect rain to be the primary precipitation type. While seasonally cool temperatures look to stick around in the northern Rockies, the Pacific Northwest along with northern and central California should see temperatures rebound to more seasonal levels today, then become above normal the second half of the week. Elsewhere across the nation, the northern Plains and Upper Midwest will be in the warm sector ahead of an approaching cold front with high temperatures soaring into 90s today. Some parts of the central High Plains could also make a run at triple digits for high temps this afternoon. Cooler conditions arrive in the northern Plains on Thursday in wake of the cold frontal passage. Severe weather is possible across the Dakotas into northern Minnesota today, then into the Midwest on Thursday as the front slowly progresses eastward. In the Southwest, elevated to critical fire weather conditions continue today due to prolonged breezy and very dry conditions. Red Flag warnings are in effect from California's Sacramento Valley to the high plains of eastern Colorado and western Kansas.
