US July 2017 Outlook

Written by on June 23, 2017 in Summer 2017, United States of America with 0 Comments

June has proved cool in the Pacific Northwest while wet and therefore cool across the South from Texas to Florida. Warm from California to Great Lakes, near average in Northeast, slightly above in Middle Atlantic.

Frequent plumes of Caribbean moisture has really taken southern Florida out of a serious drought and Tropical Storm Cindy has brought significant rainfall into Texas, Louisiana, Mississippi up into the Tennessee and Ohio Valleys and Northeast this weekend.

Let’s not forget the ongoing Southwest heatwave and recent temperatures exceeding June records and even tying all-time records.

How’s the rest of June looking?

Significant trough core centred over the Great Lakes will deliver unseasonably cool conditions into the Plains and Midwest.

Record low daytime highs and lows could be broken this weekend while staying hot in California.

How’s July looking?

Looks like the cool lingers over the Northern Tier into the Midwest in the wake of the current cold trough ending June but reversal in upper height field means a cooler Southwest but warmer Northeast.

Precipitation starts plentiful over South, Midwest and East but expect heights to build over much of the Lower 48 mid to late month with potential of building heat as precipitation eases. Always looks less hot of the wet soils of the South but heat wave conditions are possibly going to expand over the Northern Tier.
