The pattern is shifting as we head for the heart of the warm season with a much more El Nino-like upper atmosphere starting to show in the day 6-10.
For those sweating over the Mid-Atlantic and Southeast, hang in there! As the Southwest heat ridge migrates north, a trough will drop over the Great Lakes into the Ohio Valley in response. This will eventually trim heights and those upper 90s, low 100s from South Georgia into southern Virginia. Till mid this week, you may find it even hotter here and anything experienced thus far unfortunately.
The last 7 day temperature anomalies have looked like this.
June so far…
It’s cooler in the Northeast but warmer in the Southeast compared to May.

Here’s where we’re in the 5-day means through the next 15 days.
Upcoming 5 days off the ECMWF.
Significant cool down over the East in the following 5 days INCLUDING the Southeast. Notice the blow torch developing over the Pacific Northwest interior as the 594 height line climbs into eastern Washington.
500mb anomaly perspective.
Day 0-5
5-10
Check out the difference in the 500mb pattern between 24 and 120 hours from now.
A week from now and we may have the same heights that are currently over South Carolina, over northeast Washington state and a challenge to all-time records.
Highs in the Southeast may hold in the low to mid-80s with the trough coming down!
The models are printing out some incredible heat to the east of the Cascades this weekend into early next week.
ECMWF projected highs.
Saturday
Sunday
Monday
Yep both GFS and ECMWF have 110-115F east of the Cascades!
See today’s video for the GFS perspective.
