DISCUSSION

Currently, weak quasi-zonal flow is in place aloft with the upper jet well to our north. A trough/closed low is also approaching the Pacific Coast. High pressure still remains in place but has shifted further to the east. With this setup, another dry day is expected today with RH values in the 20s and recent height rises pushing highs well into the 70s. Thankfully, low-level flow/MSLP gradient remains weak. By Saturday, the trough/closed low will be moving into the western U.S. with another area of high pressure tracking to our north. This will provide dry northerly flow with more substantial height rises as ridging expands in the east. Winds will remain light overall, but highs will start rising further into the 80s. By Sunday, high pressure will be off to our northeast with 500mb heights rising to near mid-summer normals of 5,850m. This will increase broad southerly flow and make a case for highs well into the 80s. Conditions will also be breezier due to broad southerly flow and stronger MSLP gradient.
An initial system will track along the northern Great Lakes early in the week with another by the second half of the week. The frontal boundary associated with these systems will somewhat approach from the northwest, but much of the moisture and lift will remain well to our north and west. While some rain chances do move in later in the week, trends suggest this will be nowhere near what's needed to help the expanding drought. Near-record heat is likely into next week with the values listed below:
