July Outlook and Analogs

June departures so far have the mean ridge across the rockies and southwestern u.s and well as more ridging across the arctic/hudson bay area. We can see more troughiness in the pacific northwest as well as the great lakes, northeastern u.s, ontario and quebec.

Surface temperature anomalies show near normal in ontario and quebec, slightly below normal in B.C and above normal anamolies in the rockies and northern quebec where ridging showed up.

My analogs for june match up nicely with the current pattern showing pretty much the same signals at the surface and 500mb. I double weighted 2001 because it was the most similar to this year. These years are all neutral years that share similarities to the current pattern.

This is what my analogs have for july which mimics my thoughts for july. Core of heat in the rockies and could migrate slightly to the east and west. We may be exposed to shots of heat but not long lasting ones. Also we will see some fronts and cool shots coming down causing complexes of t-storms. Overall near normal.:
