U.S. Week 2-4 Outlook

Highlight: East Slowly Regains Hot Pattern Chart of the day: Last week’s temperature anomalies/rain amount Discussion: Last week was warmer than normal in much of the East just-prior to this week’s building heat wave. The West has struggled to gain hot weather despite widespread dryness. Last week wet weather dominated the Gulf region thanks to Hurricane Barry. Week 2 Ahead: July 28-August 3, 2019 Comment: Primary feature is a mid-summer polar vortex over Hudson Bay forcing cool weather into the Great Plains and causing wet conditions across Quebec. The upper ridge is weak but brings heat to the West Coast. Week 3 Ahead: August 4-10, 2019 Comment: Key to the forecast is across Texas where subtropical (and possibly tropical) rains are likely. The wet weather pattern extends to Florida. The East trends warmer while western heat backs off the coast. Week 4 Ahead: August 11-17, 2019 Comment: Heat returns to the East although not as extreme as the July heatwave. A cool air mass dips south out of Canada into the northwest Great Plains. Texas turns drier and the West is dry but avoids any important heat.
