WPC 500 MB FORECAST; MEDIUM-RANGE OUTLOOK

Based upon the latest ensemble and global model forecasts, it appears that a relatively active weather pattern will continue through at least the end of June. The jet-stream will remain relatively zonal and progressive, allowing for fast moving systems to move through occasionally. On the flip-side, temperatures will likely remain near or above normal, especially with every surge of heat from the Desert Southwest. No major heat waves or ridging is expected over the next few weeks [outside of tomorrow, Wednesday and Thursday], but there is the possibility of the Southeast ridge building into the United States by the end of June and early July which could contribute to the first heat wave we've had all summer. An active thunderstorm pattern will also remain in place, continuing the possibility of periodic heavy rain and even severe weather.
