Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 352 PM EDT Sun Jun 14 2020 Valid 00Z Mon Jun 15 2020 - 00Z Wed Jun 17 2020 ...Rain and thunderstorms expected across the Southern/Central Appalachians and Carolinas, and flash flooding is possible... ...Cool and damp conditions forecast for the Northwest... ...Severe weather possible in the Northern Plains today along with continuing heat... ...Critical Risks of fire weather continue in the Four Corners and High Plains... High pressure in control over much of the eastern U.S. makes for a cooler and mostly dry Sunday and Monday from the Great Lakes to the Northeast. Farther south, however, a stalled frontal boundary draped along the Carolina coast and an upper-level low over the Ohio Valley should generate wet weather across the Central/Southern Appalachians through tomorrow and the Carolinas through the first half of the week. 1 to 2 inches of rain are possible in portions of the Appalachians along with potentially strong thunderstorms before rain chances wind down late Monday there. Rainfall totals through Tuesday evening are forecast to be highest along the coastal Carolinas, where 3 to 5 inches of rain are expected. Rainfall rates could become intense at times, and flooding and flash flooding are possible through Tuesday. South Florida could also see some showers and thunderstorms with this system. In addition to the rain, very cool temperatures for mid-June are expected to persist into the first half of the week, with highs in the 70s and even 60s as far south as North Carolina. The Northwest will also contend with its own stretch of cool and dreary weather thanks to a pair of upper-level disturbances tracking overhead. Precipitation will fall primarily in the form of rain, but some snow could fall in the Northern Rockies and Cascades due to cooler temperatures than normal. Precipitation totals should be 1 to 2 inches in favored upslope areas. Meanwhile, ahead of the upper-level trough, ridging is forecast to persist over the Plains and build into the Midwest through the first half of the week, causing much above normal temperatures. Severe thunderstorms are possible through tonight along a cold front, and there is a Slight Risk of severe weather in place over portions of the Dakotas, with potential for another round of strong storms on Tuesday. Ahead of the western trough, gusty winds and low humidity levels are forecast across the Southwest, Rockies, and Plains. Isolated diurnal thunderstorms are possible over the Southern Rockies, but little in the way of beneficial rainfall is expected. Critical Risks of fire weather are indicated for portions of the Four Corners states and the Southern/Central High Plains today as Red Flag Warnings are in effect. Elevated to critical fire weather conditions are likely to continue into the first half of the upcoming week due to the continual presence of upper-level troughing over the Northwest.
