Extended Forecast Discussion NWS Weather Prediction Center College Park MD 216 PM EDT Mon Jun 08 2020 Valid 12Z Thu Jun 11 2020 - 12Z Mon Jun 15 2020 ...Overview and Guidance/Predictability Assessment... Over the course of this coming week/weekend, the mid-to-upper level pattern will transition to a trough over the West, ridge over the Plains and a trough over the East; amplifying with time as well once the remnant energy of Cristobal exits to the East. In general, model guidance and the ensemble means remain in decent agreement with typical spread in specific details by the end of the extended period, particularly with the trough moving into the West. Maintained continuity for the evolution of this pattern by primarily using the 00Z ECWMF, 00Z/06Z GFS and their respective ensemble means. The evolution of the system near the Bermuda continues to be uncertain. NHC will continue to monitor this system in their outlooks. ...Weather/Hazard Highlights... With ridging in place over the Rockies and High Plains, temperatures will be averaging 5 to 15 degrees warmer than usual for mid-June. Cooler temperatures will be brought into the region as a slow-moving cold front tracks eastward. Behind the front, temperatures will be 5 to 15 degrees cooler than average across the Pacific Northwest and surrounding area this weekend. With the pattern switch mentioned above, a large portion of the country will have little to no precipitation. This will be helpful for soil saturation recoveries after several inches of rain dumped in association with tropical cyclone Cristobal. Some modest rain may accompany the front over the East and into the Southeast with perhaps a surge on Sunday along the East Coast as the front slumps eastward. Precipitation will increase across the Pacific Northwest was the leading Pacific front approaches and pushes inland toward the Great Basin and Intermountain West, especially in the areas of higher terrain where enhanced precipitation is favored. Once this front exits the Rockies late in the extended period, coverage of precipitation over the Plains may increase.
