Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 502 PM EDT Fri Jun 12 2020 Valid 00Z Sat Jun 13 2020 - 00Z Mon Jun 15 2020 ...Flash flooding possible along the Southeast coast today due to heavy showers and thunderstorms... ...Stormy and cooler conditions in the Northwest, hot conditions in the Plains... ...Elevated to critical fire threat continues over the Great Basin and southern Plains, high winds in the Intermountain West... Much of the Lower 48 can expect a mostly dry end to work-week and start to the weekend. A couple regions will still need the umbrella handy, however, with the coastal Southeast at risk for the heaviest rainfall totals. The active setup along the Southeast coast is due to a quasi-stationary frontal boundary that will act to trigger showers and thunderstorms. Rainfall could be very heavy at times today and with overly saturated soil in place, a Slight Risk for flash flooding has been issued for the Southeast coast. Showers and thunderstorms look to remain in the forecast throughout the weekend along the Southeast coast with localized flash flooding possible. Rainfall chances increase in the southern Appalachians the second half of the weekend as an upper level disturbance deepens over the region starting Sunday. Wet conditions are also anticipated from the Sierra Nevada to the Northwest today thanks to a potent upper level trough tracking over the West Coast. Scattered showers and storms will pass through the Northwest with some severe storms possible in the northern Rockies this afternoon and evening. A strong cold front will usher in below normal temperatures along the West Coast today followed by the Great Basin and northern Rockies on Saturday. While the West cools down this weekend, the Plains are likely to be mired in hot temperatures today and Saturday as high temperatures exceeding 90 degrees stretch from Texas on north to the high plains of Montana. The combination of an intensifying low pressure system over the Northwest and strong high pressure over the Great Lakes will make for a windy Friday and weekend over the Great Basin, the southern Rockies, and the southern High Plains. The combination of dry thunderstorms along with low humidity and windy conditions over parts of the Great Basin and these regions will aid in producing favorable fire weather conditions today into the weekend. Some winds could be quite strong as high wind warnings and watches have been posted for parts of the Great Basin today and northern Rockies on Saturday where wind gusts could reach as high as 60 miles per hour.
