Summer Forecast



La Nina will remain intact throughout the summer, although weakening above a -.6C anomally. This is following a moderate to strong Nina winter. QBO is neutral nearing positive phase and should last at least through October. March AMO is the 6th highest on record which will be a major factor.

Analogs for this summer: 1999, mid 1950's, and mid 1930's.

West should be near to below normal. Midwest and Ohio Valley will see significant heat waves especially June to July. Heat will shift east for August with main focus on the Mid Atlantic region.

West: -1 to +1
Midwest and Ohio Valley: +2 to +5
South: -1 to +1
Mid Atlantic: +1 to +3
Great Lakes and Northeast: 0 to +2
