.DISCUSSION...
Issued at 226 AM EDT Fri Apr 10 2026

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:
