North Atlantic Tropics Starting To Look More Favorable

We now have 3 tropical waves in the outer tropical North Atlantic basin. Each tropical wave is located over 80-81F water which is marginally supportive for development. The upper shear axis stretches across the southern Caribbean Sea and northwest of the tropical waves. However, the shear axis is not particularly strong. Meanwhile upper shear is very light across the northern Caribbean Sea and Bahamas (where surface water is generally warmer than normal).

The Stubborn Western Russia Trough

The most impressive upper level feature in the northern hemisphere since springtime has been the persistent and vigorous upper level cool and showery trough over Western Russia. Occasionally, upstream from the deep trough an amplified ridge forms to bring heat wave conditions to Europe centered on France. Otherwise the trough takes over and squashes heat and this time leads to wet weather over France next week after the torrid heat this week.
