Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 503 PM EDT Fri Jun 12 2020 Valid 00Z Sat Jun 13 2020 - 00Z Mon Jun 15 2020 ...Flash flooding possible along the Southeast coast tonight due to heavy showers and thunderstorms... ...Cooler in the Northwest, Northeast and Mid-Atlantic this weekend... ...Elevated to critical fire risk continues over the Great Basin and Southern Plains, high winds impact the Intermountain West and Northern Plains... Heavy rainfall and thunderstorms will continue across the Southeast coast tonight along a stationary boundary extending from the Gulf of Mexico up and through the Carolina coast. A Slight Risk of Excessive Rainfall is in effect for this area as a result. This frontal pattern will persist through the weekend and into the beginning of the work week, but most of the heaviest rainfall will remain offshore. We're monitoring a chance for localized heavy rainfall over the Central Appalachians next week. Rain along with cool maritime air will return to the Pacific Northwest this weekend following a low pressure system that is currently moving across the Great Basin and Intermountain West, all underneath a deep upper level trough. Snowfall may fall over higher elevations of the Northern Rockies. Building high pressure over Ontario will continue to push a cold front down through the Northeast and into the Mid-Atlantic bringing with it below average temperatures to those areas this weekend. High pressure will be nestled between the two troughs over the Great Plains. This will generate above average heat for the Rockies and Great Plains this weekend. Temperatures will be particularly higher over the Northern Rockies/Plains on Saturday as highs are likely to be 30 degrees above average in certain places. The Storm Prediction Center continued its issuance of Elevated and Critical Risk of Fire Weather for parts of the Great Basin and Southwest. This, due in-part by the previously mentioned upper-level ridge producing heat and dry conditions over this region. Dry thunderstorms and high winds will also contribute to the risk of fires this weekend. Kebede Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
